Answer:

3 red golf balls

Step-by-step explanation:

There are 2 red golf balls and 6 other golf balls, so there is a total of 8 golf balls. 6 + 2 = 8

Now find the probability of selecting a red golf ball

(p of red) = 2/8

reduce

(p of red) = 1/4

Now multiply the probability by 12 to how many you expect to be red.

1/4 x 12/1

12/4 = 3

3 red golf balls

What was Pam's starting salary?

Pam's current salary for 5 years = $73.500

Her salary went up for 122.5% in 5 years.
a = her starting salary

First, we will make an equation of this problem.

Let's use a as the symbol of her starting salary

equation that we are going to use
73500 = 122.5% x a

Next, we move a to the left and we want to divide 73500 with 122.5%
a = 73500 / (122.5/100)

Next, we want to divide 73500 with 1.225 since we've done dividing 122.5 with 100
a = 73500 / 1.225
a = 60000

Finally, we got the answer of Pam's starting salary was $60.000

Answer:

y = -2x + 9              y =1/9x + 4/9

Step-by-step explanation:

-9/2 = -x -1/2y

-1/2y = x - 9/2

y = -2x + 9

-4 - x = -9y

-9y = -4 - x

y = 1/9x + 4/9

Answer:

- 56

Step-by-step explanation:

First solve the parenthesis,

(6 - 8) = 2

(9 - 10) = -1

(4 + 2) = 6

(6 + 3) = 9

The equation now looks like; (2)(-1) - (6)(9).

Now solve the parenthesis again,

(2 x -1) - (6 x 9)

2 x -1 = -2

6 x 9 = 54

Now, complete the last equation,

-2 - 54 = -56

-56 is the answer!

Step-by-step explanation:

\(b(1) = 4\)

Since this is an arithmetic sequence, notice that if you subtract b(1) (i.e., 4) from b(2)(i.e., 22), you get 18. Likewise, if you subtract b(2) from b(3) you also get 18. Therefore,

\(b(n) = b(n-1) + 18\)

A mathematical statement that has an "equal to" symbol between two expressions with equal values is called an equation.

As in 3x + 5 Equals 15, for instance.

Equations come in a variety of forms, including linear, quadratic, cubic, and others.

So, take dudes as x and ladies as y.

Now, form the required 2 equations as follows:
2x + y = 45 ...(1)

x + y = 35 ...(2)

Work on equation (2):

x + y = 35

x = 35 - y

Now, substitute x = 35 - y in equation (1):

2x + y = 45

2(35-y) + y = 45

70 - 2y + y = 45

-y = -25

y = 25

Since ladies were charged $1 for each ticket, then 25 ladies attended the party.

Therefore, after solving the equations, we know that a total of 25 ladies attended the party.

The image of the point L(-4,0) after a dilation with a center of (0,0) and a scale factor of 7 is the point L'(-28,0).

A dilation with a center of (0,0) and a scale factor of 7 means that every point in the plane will be multiplied by a factor of 7 from the origin.

To find the image of the point L(-4,0) after a dilation with a center of (0,0) and a scale factor of 7, we can simply multiply the coordinates of L by the scale factor.

The coordinates of the image point L' will be:

L' = (-4 × 7, 0 × 7) = (-28, 0)

Step-by-step explanation:

The situation described can be modeled using a linear equation, where the balance of the savings account increases by a fixed amount every month. Specifically, the equation that represents this situation is:

balance = $5000 + $825 * months

where "months" represents the number of months that have passed since the account was opened. The slope of this line is constant at $825, indicating that the balance is increasing by the same amount every month.

Therefore, the model for this situation is linear.

Suppose that the relationship between the tax rate t on imported shoes and the total sales S (in millions of dollars) is given by the function below. The tax rate t that maximizes revenue for the government is 66.992%.

Revenue can be defined as the amount or the income a person or an organization generated from the sales of goods and services.

Given function :

Total sale  = S(t) = 7−6∛t

Hence,

Expression for Revenue rate = r(t) = tS(t)

Now let substitute and solve  expression

r(t) = t (7−6∛t)

= 7t−6(t)^4/3

Differentiate the expression

d[r(t)] dt = r′(t)

r′(t) = 7− (4/ 3) 6(t)^1/3

=7−8(t) ^1/3 ........ expression (1)

Maximum revenue

r′(t) = 0

Substitute and solve expression (1)

0 =7−8(t)^1/3

(t) = (7/8)^3

= 0.66992 × 100

= 66.992%

Therefore we can conclude that the tax rate t that maximizes revenue is 66.992%.

A cylinder has two types of edges: the curved edges and the top and bottom edges.

A cylinder is a three-dimensional geometric shape that consists of two circular bases and a curved surface connecting the bases. The circular bases have a certain number of edges, depending on the number of sides each base has.

Since a circle has no straight edges, the circular bases of a cylinder do not contribute any edges.

The curved surface of a cylinder has no straight edges either, as it consists of a smooth, continuous surface.

Therefore, the curved surface does not contribute any edges to the cylinder.

The only remaining edges are the top and bottom edges of the cylinder. Each base of the cylinder has a single edge that runs along the circumference of the circular base.

Hence, the cylinder has two edges from its top and bottom bases.

Answer:

0.1169

Step-by-step explanation:

We solve the question using the z score formula

z = (x-μ)/σ/√n where

x is the raw score = 4800 miles

μ is the population mean = 4550 miles

σ is the population standard deviation = 1470 miles

n is the random number of samples = 49 drivers

Greater than sign = >

For x > 4800 miles

z = 4800 - 4550/1470/√49

= 4800 - 4550/1470/7

= 4800 - 4550/210

= 1.19048

Probability value from Z-Table:

P(x<4800) = 0.88307

P(x>4800) = 1 - P(x<4800)

P(x>4800) = 1 - 0.88307

P(x>4800) = 0.11693

Approximately to 4 decimal places = 0.1169

Therefore, the probability that these drivers have a sample mean greater than 4800 miles is 0.1169

The minimum payment on Card A is 1.30$ greater than on Card B.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

We are given that Mindy has two credit cards, A and B. Card A has a balance of $721.24 and Card B has a balance of $978.74.

The minimum monthly payment on Card A = 3.64% of the total balance,

The minimum monthly payment on Card B = 2.55% of the total balance.

Then ;

Card A = 3.64% of the total balance,

3.64% x 721.24

= 2625.31/100

Answer:

To locate the number 8 and its opposite on the number line, we can use the given number line:

-8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7

Number 8 is located to the right of zero. Its opposite can be found by moving an equal distance to the left of zero. Since the number line is symmetric about zero, the opposite of 8 would be -8.

-8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7

↑ ↑

So, the opposite of 8 is -8. They are related to zero as equal distances on opposite sides of zero on the number line.

Now, let's address exercises 2-3:

a. To locate the opposite of 9, we need to move an equal distance to the left of zero. The opposite of 9 is -9.

-8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7

Answer:

Step-by-step explanation:

The total cost C of construction as a function of h is:

\(C = \frac{10 + 5\sqrt{2}~ h^2}{h}\)

As the pen is in the shape of an isosceles right angle, one of the

angle must be 90 degrees.

Also, the two sides of the triangle are equal and the base angles

are equal.

Here, x represents the length of legs of isosceles right triangle

and h be the length of hypotenuse of isosceles right triangle

Using Pythagoras theorem,

x² + x² = h²

2x² = h²

x² = h² / 2

x = \(\sqrt{\frac{h^2}{2} }\)

So, x = \(\frac{h}{\sqrt{2} }\)

The fencing costs $5 per feet for the legs and $10 per feet for the hypotenuse.

So, the fencing cost for the legs would be,

= 5 × (2x)

= 10x

= \(10\times \frac{h}{\sqrt{2} }\)

= \(5\sqrt{2}~ h\)

And the fencing cost for the hypotenuse would be,

= 10/ h

So, the total cost of fencing C would be,

\(C = \frac{10}{h} + 5\sqrt{2}~ h\\\\C = \frac{10 + 5\sqrt{2}~ h^2}{h}\)
