As a salesperson at Roaring Waves Beach Supplies, Carissa receives a monthly base pay plus commission on all that she sells. If

babymother [125]

y = her salary,
m = rate of commission,
x = amount of merchandise sold
b = monthly base pay

sets of data to calculate the formula
(500, 405) and (900, 489)

use the slope formula to find m:
(489 - 405) / (900 - 500)
m= 84 / 400 = 0.21 (21% commission)

find the base pay by substituting known values for x,y, and m, then solve for b:
405 = (0.21)(500) + b
405 = 105 + b
b = 300

now we know the equation for her salary is:
y = 0.21x + 300

To find the salary when she sells $1,700 worth of merchandise, put 1700 for x and solve for y:
y = 0.21(1700) + 300 = 657

The table of values shows the height of a car of a Ferris wheel as it travels in a circular motion. Which statements are true? S

Mashutka [201]

Answer:

The true statements are;

The car makes one complete revolution in 12 s

The radius of the Ferris wheel is 25 yd

Step-by-step explanation:

The values of the table of the given Ferris wheel are presented here as follows;

$\begin{array}{cc}Time \ (seconds) &Height \ (yards)\\0&30\\3&55\\6&30\\9&5\\12&30\\15&55\\18&30\\21&5\\24&30\end{array}$

From the table, we have;

The time it takes the Ferris wheel to complete a motion round from a height of 30 yards and back to 30 yards which is one revolution = 12 s

∴ The time it takes the car to complete one revolution = 12 s

The maximum height of the Ferris wheel = 55 yards

The lowest height of the Ferris wheel = 5 yards

The time at which the Ferris wheel is at the lowest height = 9 s, and 21 s

If the car is loaded at 0 s, then people are loaded above the lowest height of the Ferris wheel

The diameter of the Ferris wheel = The maximum height of the Ferris wheel - The minimum height of the Ferris wheel

∴ The diameter of the Ferris wheel = 55 yards - 5 yards = 50 yards

The radius of the Ferris wheel, R = 1/2 × The diameter of the Ferris wheel

∴ The radius of the Ferris wheel, R = 1/2 × 50 yards = 25 yards

Therefore, the true statements are;

The car makes one complete revolution in 12 s

The radius of the Ferris wheel is 25 yd.

1. Mrs. Verner's class has

Dmitrij [34]

Answer:

46.7%

Step-by-step explanation:

Given:

Total number of students in Mrs. Verner's class = 15

Number of girls = 8

To find: percentage are boys

Solution:

Percentage of boys = ( Number of boys / Total number of students ) × 100

Number of boys = Total number of students - Number of girls = 15 - 8 = 7

So,

Percentage of boys = $\frac{7}{15}$ × 100 = 46.7%

The graph of f(x)=3•2^x -3 is shown below. G(x) is a transformation of f(x). How would you write the equation for the function g

Bezzdna [24]

Answer:

C

Step-by-step explanation:

To find the appropriate equation, notice the red graph has shifted up about 6 units. This means that $3*2^x-3$ which is shifted by -3 will move 6 up. -3+6= 3. This means the function will have +3. Only B and C are options. Now test a point. Notice the red function crosses the y-axis at about 5 or 6 when x=0.

$g(x) = 2^x+3\\g(0) = 2^0+3\\g(0)=1+3\\g(0)=4$

This function doesn't match.

$f(0) = 3*2^0+3\\f(0) = 3*1+3\\f(0)=6$

This function matches. Option C is correct.
