find the total cost 35$ with 50% discount

Answer: B)

Step-by-step explanation:

By checking which graph is satisfied, we choose points that the function has pass through.

First, we know that y = mx + b, where m is the slope, how the line change; and b is the y-intercept. In this equation, the slope is 24 which the line is increased. So we can eliminate the choice D, the line in D decreased.

Then we find where the first point and second point this graph will be.

When x = 0, y = 24x = 24(0) = 0, (0,24)

When x = 1, y = 24x = 24(1) = 24, (1,24)

1 package can have 24 cookies, only B have 24 cookies in 1 package.

After performing the operation, the simplified expression is (192 + 5x)/8.is (192 + 5x)/8.

To perform the indicated operation, 3x8+5x/8, we follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). Let's break down the given expression step by step:

Step 1. Multiply: 3 multiplied by 8 equals 24.

Step 2. Divide: Divide 5x by 8. This can be written as 5x/8. Now, we have simplified the expression to 24 + 5x/8. To further simplify, we need a common denominator. Since 8 is the denominator for 5x/8, we can rewrite 24 as 24/1.

Step 3. Add: Now we can add the two fractions together. The common denominator is 8, so we multiply the numerator and denominator of 24/1 by 8 to make it 192/8. Adding the fractions gives us: (192 + 5x)/8.

12. D)11

Step-by-step explanation:

11. We substitute x with 12 in 3(x)-11.

3(12)-11=

36-11= 25

We substitute x with 12 for the second equation (x+13).

12+13=25

Both answers match so the answer for #11 is 12.

12.We substitute x with 11 in 4(x)-4.

4(11)-4=

44-4=40

We substitute x with 11 for the second equation (2(x)+18)

2(11)+18=

Both answers match so the answer for #12 is 11.

The equation of the following graph in vertex form is y = (x + 1)².  This equation represents a parabola with its vertex at the point (-1, 0) and opening upwards.

The equation of a quadratic function in vertex form. The vertex form of a quadratic function is given by the equation:

y = a(x - h)² + k

In this equation, (h, k) represents the vertex of the parabola, and 'a' determines the direction and shape of the parabola. The points given are (0, 1), (-1, 0), and the term (x + 1)² is also mentioned.

Using these details, the vertex of the parabola can be identified as (-1, 0), since the term (x + 1)² is present, which corresponds to h = -1. The point (0, 1) can be used to determine the value of 'a'. Plugging in the coordinates (0, 1) into the vertex form equation:

1 = a(0 - (-1))² + 0

1 = a(1²)

a = 1

With these values, the equation of the graph in vertex form is:

y = (x + 1)²

This equation represents a parabola with its vertex at the point (-1, 0) and opening upwards.

Let us assume donuts should be represented as ’D’. And the four donuts can be represented as ‘DDDD’.

Now, as per the question, there are three types of donuts and they are glazed, chocolate and powdered. Divide the donut into two parts as first one is glazed, second is chocolate and third is powdered. And the quantity of glazed is one, chocolate is two and powdered is one. And the total object is six. Therefore, the probability can be written as:

\(P(E) = \frac{6P2}{2} = 15 ways.\)

Each part of the question is answered above and the angles are given below.

Given are the angles as mentioned in the question.

[1] -

Since, angle [1] and angle [4] are vertically opposite angles, we can write-

3x + 14 = 5x - 52

14 + 52 = 5x - 3x

2x = 66

x = 33

∠1 = 3x + 14 = 3 x 33 + 14 = 99 + 14 = 113°

∠1 = 113°

[2] -

Since, angle [A] and angle [B] are supplementary angles, we can write-

(3x + 8) + {(2/3)x + 62} = 180

3x + 8 + 62 + (2/3)x = 180

3x + (2/3)x = 110

x{3 + 2/3} = 110

x{(9 + 2)/3} = 110

(11/3)x = 110

x = (110 x 3)/11

x = 30

∠A = 3x + 8 = 3 x 30 + 8 = 98°

∠A = 98°

∠A = (2/3)x + 62 = 2/3 x 30 + 62 = 82°

∠B = 82°

[3] -

Since, angle [2] and angle [3] are  vertically opposite angles, we can write -

13x + 27 = 9x + 59

13x - 9x = 59 - 27

4x = 32

x = 8

∠2 = 13x + 27 = 13 x 8 + 27 = 104 + 27 = 131°

∠2 = 131°

∠3 = 9x + 59 = 9 x 8 + 59 = 72 + 59 = 131°

∠3 = 131°

To determine if it is appropriate to use the given sample of 120 individuals, with 7 of them having a college degree, to calculate a 95% confidence interval for the percent of all California residents with a college degree, we can apply the rule of thumb for sample size.

The rule of thumb states that for estimating proportions, a sample size should be large enough so that both the number of successes (in this case, individuals with a college degree) and failures (individuals without a college degree) are at least 10.

In the given sample, there are 7 individuals with a college degree. To determine if this meets the rule of thumb, we need to ensure that both the number of successes and failures are at least 10. Since the sample size is 120, the number of failures can be calculated as 120 - 7 = 113.

Since both the number of successes (7) and failures (113) are above 10, the rule of thumb is satisfied. Therefore, it is acceptable to use these numbers to calculate a 95% confidence interval for the percentage of all California residents with a college degree.

Answer:

D. x^2-x-9-12/x-2

Step-by-step explanation:

We can use synthetic division to divide (x^3 - 3x^2 - 7x + 6) by (x - 2). First, we set up the division as follows:

    2 |   1   -3   -7    6

       |______2___-2__-18

       | 1   -1   -9  -12

The numbers on the bottom row of the synthetic division table represent the coefficients of the quotient polynomial. Therefore, the quotient is x^2 - x - 9, and the remainder is -12.

So, we have:

(x^3 - 3x^2 - 7x + 6) / (x - 2) = x^2 - x - 9 + (-12 / x - 2)

Therefore, the correct option is D: x^2 - x - 9 - 12/(x - 2).

Step-by-step explanation:

Given equation:

\(y=256-16x^2\)

where:

The penny reaches the ground when the height is zero, so when y = 0.

Substitute y = 0 into the given equation and solve for x:

\(\begin{aligned}y&=256-16x^2\\y=0 \implies 0&=256-16x^2\\0+16x^2&=256-16x^2+16x^2\\16x^2&=256\\\dfrac{16x^2}{16}&=\dfrac{256}{16}\\x^2&=16\\\sqrt{x^2}&=\sqrt{16}\\x&=\pm4\end{aligned}\)

As time is positive, x = 4 only.

Therefore, it takes 4 seconds for the penny to reach the ground.

Answer:

Kelly is 19; Brandon is 13

Step-by-step explanation:

k + b = 32.  Also:  k = b + 6.

Substituting b + 6 for k in the first equation, we get b + 6 + b = 32, or

2b = 26.  Then b must be 13, and k must be 13 + 6, or 19.

Kelly is 19; Brandon is 13.

Answer:

Brandon is 13, Kelly is 19.

Step-by-step explanation:

Let's set up our equations.

Kelly and Brandon have a combined age of 32.

K + B = 32

They have an age difference of 6. Kelly is older.

K - B = 6

Let's shift the equation around a little.

K - B = 6

Add B to both sides.

K = B + 6

Now let's plug K into our first equation.

K + B = 32

(B + 6) + B = 32

Combine like terms.

2B + 6 = 32

2B = 26

Divide both sides by 2.

B = 13

Now that we know Brandon is 13, we can find Kelly's age.

K + B = 32

K + 13 = 32

K = 19

Kelly is 19.

if OPQR is a rectangle, rhombus, or square. However, we can say that it is a parallelogram.

A parallelogram is a quadrilateral (a polygon with four sides) in which opposite sides are parallel and have the same length. It can also be defined as a flat shape with four straight sides where opposite sides are parallel and opposite angles are equal. The two pairs of parallel sides are referred to as bases and heights can be measured as the perpendicular distance between the two parallel sides. The area of a parallelogram can be found by multiplying the length of the base by the height. Parallelograms can have different shapes and sizes, but they always have opposite sides that are parallel and congruent angles across from each other.

we can draw a rough sketch of quadrilateral OPQR and label the slopes of its sides as follows:

     Q

     |    \

     |      \

   8 |       \ 4/7

     |          \

     |            \

     O-   -   - -P

       4/7

We can see that OP and QR have the same slope of 4/7, which means they are parallel. Similarly, PQ and RO have the same slope of 8, which means they are also parallel. Therefore, quadrilateral OPQR is a parallelogram.

To further classify the type of parallelogram, we can use the fact that opposite sides of a parallelogram are equal in length and parallel. Since we do not have any information about the lengths of the sides, we cannot determine if OPQR is a rectangle, rhombus, or square. However, we can say that it is a parallelogram.
