84 is 35% of which of the following value

Answer:

$22

Step-by-step explanation:

There are two lines, which is less than 3, so the total cost is (11)(2) = $22.

Answer:

B

Step-by-step explanation:

On a coordinate plane, parallel lines have the same slope as geometric figures are true. Thus option B is correct.

Marks, splines, spheres, and curved are used to build enclosed geometric shapes. We can see these shapes all around us. Illustrations of geometric shapes include circles, rectangles, triangles, and others. Any configuration of points, columns, or angles is a geometry figure.

A point is the most fundamental algebraic concept because it has no boundaries. Simply put, a point upon that plane is a location. A dot is used to symbolize it. A plane can be identified by three non-straight-line points.

As two or much more vectors seldom cross each other and are located on the same dimension, these are said to be parallel. The slope of these lines is constant. Coplanar lines that seem to be parallel are the ones that don't cross. Therefore, option B is the correct option.

The approximate probability that all four seniors will be chosen at random is 0.48%.

To calculate the approximate probability that all four seniors will be chosen at random out of four seniors and six juniors competing for four places on a quiz bowl team, we need to consider the total number of ways to choose four students out of the ten, as well as the specific number of ways to choose all four seniors.

The total number of ways to choose four students out of the ten is given by the combination formula:

C(n, r) = n! / (r!(n - r)!)

Where n is the total number of students (10 in this case) and r is the number of students to be chosen (4 in this case).

So, the total number of ways to choose four students out of ten is:

C(10, 4) = 10! / (4!(10 - 4)!) = 210

Now, we need to determine the number of ways to choose all four seniors out of the four available senior spots. Since we are choosing all four seniors, there is only one way to do so.

Therefore, the probability of choosing all four seniors is:

Probability = (Number of ways to choose all four seniors) / (Total number of ways to choose four students)

Probability = 1 / 210

Approximately, the probability is 0.0048 or 0.48%.

Answer: y = -3/5x - 6

Step-by-step explanation:

There are a few equations that can be used for this, but the simplest one would be y = mx + b

We are given:

y = -3

m = -3/5 (slope)

x = -5

b = ?

Our equation is this, we are solving for b

==> -3 = -3/5 ( -5) + b

==> -3 = -3/5 ( -5) + b ( multiply the brackets)

==> -3 = 3 + b ( subtract 3 to both sides)

==> -6 = b

Now we can make the desired equation in slope intercept form;

y = -3/5x - 6

After answering the provided question, we can conclude that t = 1.833 is standard deviation the critical value for a one-tailed t-test with 9 degrees of freedom and a significance level of 0.05.

A statistic that communicates the fluctuation or variance of a number set is the standard deviation. A high standard deviation indicates that the values seem to be more dispersed, whereas a low standard deviation indicates that the values are closer to the established mean. The standard deviation is a measure of how far the data varies from the mean (or ). So when standard deviation is small, the data tends to cluster around the mean; when it is huge, the data is more dispersed. The standard deviation represents the average variability of something like the data set. It displays the average deviation from the mean of each score.

To decide whether the new manufacturing technique should be used, we must first determine whether the standard deviation of the drug concentration in the new process is less than 4 g/l. A hypothesis test can be used with the following null and alternative hypotheses:

H0 (null hypothesis): In the new process, the standard deviation of drug concentration is 4 g/l.

Alternative hypothesis (Ha): In the new process, the standard deviation of drug concentration is less than 4 g/l.

For the standard deviation, we can use a one-tailed t-test with a

\(t = (n - 1) * s^2 / \sigma^2\\s = \sqrt(1/(n-1) * \sum(xi - x\bar)^2) = 0.004 g/l\\t = (n - 1) * s^2 / \sigma^2 = (10 - 1) * 0.004^2 / 4^2 = 0.0007\)

t = 1.833 is the critical value for a one-tailed t-test with 9 degrees of freedom and a significance level of 0.05.

20x -1500 > 3500

company charges $20 per shirt

$1500 = fixed cost

x Is the number of T-shirts. that needed to be sold for the company to meet its goal.

Since x is multiplied by 20 which is the charge per shirt, it is the number of t-shirts ( not profit )

Step-by-step explanation:

I am not sure I understand the numbers in the description, but I assume you meant that

the baseline is x/2 meter,

the height to the baseline is also x/2 meter.

the area is 32 m².

the area of a triangle is

baseline × height / 2.

so, here we have

32 = x/2 × x/2 / 2 = x²/4 / 2 = x²/8

x² = 32×8 = 256

x = 16 m

so the base and the height are both 16/2 = 8 m long.

The rate constants are measured in units of 1/s. The temperatures range from 310 K to 350 K, and the corresponding rate constants increase as the temperature increases.

The rate constant of a reaction is a measure of how fast the reaction proceeds. It is influenced by temperature and is typically determined experimentally. The table provides data on the rate constant at different temperatures.

Upon examining the data, we observe that as the temperature increases from 310 K to 350 K, the rate constant values also increase. This trend suggests that the reaction proceeds at a faster rate at higher temperatures.

The rate constant's dependence on temperature can be explained by the Arrhenius equation, which states that the rate constant is exponentially related to the temperature. As the temperature rises, more reactant molecules possess sufficient energy to overcome the activation energy barrier, leading to an increase in the reaction rate.

The data in the table support this concept, as the rate constants progressively increase with higher temperatures. This information can be utilized to study the reaction kinetics, predict reaction rates at different temperatures, and assess the effect of temperature on the reaction's progress.

Answer:

x = 2 or -2

Step-by-step explanation:

This is a regular hexagon

To find the value of x we will have to find the sum of interior angles first and to do that:

(n-2)*180 (n is the number of angles)

(6-2)*180 = 720 is the sum of all six angles

since this is a regular hexagon, all angles has equal measures so

720/6 = 120 now

30x^2 = 120 divide both sides by 30

x^2 = 4 find the root of both sides

x = 2 or -2

The labeled angle is what's called an inscribed angle. There's a theorem (fittingly called the inscribed angle theorem) that says the measure of this angle is half the measure of the circular arc that it subtends.

In this case, the angle is subtended by an arc measuring 180°. So

(4x + 6)° = 1/2 • 180°

4x + 6 = 90

4x = 84

x = 21

We will divide by 11 and multiply by 9.

The first number is 110 and the second number is 90.

Here we have to go from the first number to the second number.

So for this, we will divide the first number by 11, so we get

110/11= 10

Now we will multiply it by 9, so we get

10 × 9 = 90

So by multiplying the first number by 11 and then multiplying it by 9 we will get the second number.

Answer:

a. To write a system of equations with exactly 1 solution, we need to find two equations that intersect at a single point. We can choose any two of the given equations and solve for x and y to find their point of intersection:

From y = 4x + 2 and y = 9x + 2, we have:

4x + 2 = 9x + 2

-5x = 0

x = 0

Substituting x = 0 into either equation gives us y = 2. Therefore, the system of equations with exactly 1 solution is:

y = 4x + 2

y = 9x + 2

b. To write a system of equations with exactly no solutions, we need to find two equations that are parallel and never intersect. We can choose any two of the given equations that have different slopes (since parallel lines have the same slope) and different y-intercepts.

From y = 4x + 2 and y = 9x + 2, we see that they have the same y-intercept (2), so they cannot be parallel.

However, if we choose y = 4x + 2 and y = 9x + 5, we have:

4x + 2 = 9x + 5

-5x = 3

x = -3/5

Substituting x = -3/5 into either equation gives us y = -8/5. Therefore, the system of equations with exactly no solutions is:

y = 4x + 2

y = 9x + 5

Answer:

the answer to the first question is B.

Step-by-step explanation:

In this situation, the wholesale cost x of every dress is first increased by $20 to obtain the retail price. This is represented by the function f(x) = x + 20.

Then, during a sale, every dress is sold for 75% of the retail price. This is represented by the function g(x) = 0.75x.

To find the composite function gf that describes this situation, we need to substitute f(x) into g(x) and simplify.

gf = g(f(x)) = g(x + 20) = 0.75(x + 20) = 0.75x + 0.75(20) = 0.75x + 15

Therefore, gf = 0.75x + 15 describes the situation where the wholesale cost x of every dress is first increased by $20 to obtain the retail price, and then during a sale, every dress is sold for 75% of the retail price. So, the final cost of the dress is (0.75x + 15)

So, the composite function gf = 0.75x + 15, describes the situation where the shop adds $20 to the wholesale cost, and then sells it for 75% of the retail price.

To calculate the cash balance at the end of the period, we need to consider the cash inflows and outflows.

Starting cash balance: $4,520

Cash inflows: $1,654 (receivables collected)

Cash outflows: $1,961 (payments to suppliers) + $500 (cash expenses)

Total cash inflows: $1,654

Total cash outflows: $1,961 + $500 = $2,461

To calculate the cash balance at the end of the period, we subtract the total cash outflows from the starting cash balance and add the total cash inflows:

Cash balance at the end of the period = Starting cash balance + Total cash inflows - Total cash outflows

Cash balance at the end of the period = $4,520 + $1,654 - $2,461

Cash balance at the end of the period = $4,520 - $807

Cash balance at the end of the period = $3,713

Step-by-step explanation:

i divided 7.5 by 12.5 and got 0.6 and added 4.2 and got 4.8

Equation is formed of two expressions. The amount of water that is used by Sofia to make the slime is 4.8 fl oz.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the amount of salt solution used by Sofia be x, and the amount of water used by Sofia be y.

As it is given that the amount of glue used is 12.5 times the amount of salt solution used, and the amount of glue used is 7.5 fl oz. Therefore, the equation can be written as,

Amount of glue = 12.5 x Amount of salt solution

\(7.5 = 12.5 \times x\\\\x = \dfrac{7.5}{12.5}\\\\x = 0.6\)

Also, it is given that the amount of water used is 4.2 fl oz. less than the amount of salt solution used, since we know the amount of salt solution used, therefore, the equation can be written as,

Amount of salt solution = Amount of water - 4.2 oz

\(x = y -4.2\\\\(0.6)=y-4.2\\\\y = 4.8\)

Hence, the amount of water that is used by Sofia to make the slime is 4.8 fl oz.

The relation 2 represents a function.

In order to determine which relation in the below table represents a function, we need to first understand what a function is.A function is a relationship in which each input value corresponds to exactly one output value.

To put it another way, each x-value has one and only one y-value. The most typical method to determine whether a relation is a function is to use the vertical line test.

The vertical line test is a way to determine if a relation is a function graphically. To test if a graph is a function, we draw a vertical line through each x-value on the graph. If a vertical line crosses the graph more than once, it is not a function.

If, on the other hand, the graph passes the vertical line test and no vertical line crosses the graph more than once, it is a function.Now let's look at the table below to determine which relation is a function.

We will first plot the x and y values of each relation on a coordinate system and then apply the vertical line test to each relation.

Relation 1: x | y0 | 10 | 11 | 22 | 23 | 34 | 35 | 4Relation 1 does not represent a function since we can draw a vertical line through x = 3 and the line will cross the graph more than once.

Relation 2: x | y2 | 33 | 34 | 45 | 46 | 57 | 5Relation 2 represents a function since we can draw a vertical line through each x-value on the graph and it will only cross the graph once.

I hope this helps you

:)

Answer:

∠ABC = 72°

Step-by-step explanation:

When we look at the triangle carefully, we can see a bar on AC and AB. Those bars define that AC and AB are equivalent. This also means that the triangle is isosceles. Since this triangle is isosceles, the base angles of the triangle are equivalent.

⇒ AB = AC

We also know that the sum of its interior angles must be 180°.

⇒ ∠A + ∠B + ∠C = 180

Let's substitute their angle measures.

⇒ 3x + 6x + 6x = 180                                         [∠BAC = 3x; ∠ABC = ∠ACB = 6x]

Now, let's solve for x.

⇒ 3x + 6x + 6x = 180

⇒ 15x = 180

⇒ 15x/15 = 180/15

⇒ x = 12

Now, substitute the value of x into "6x" to find ∠ABC.

∠ABC = 6x

⇒ ∠ABC = 6(12)

⇒ ∠ABC = 72°
