Write an equation that relates the number of tennis balls (y), with the number of cans (x). (Do not put spaces between numbers, variables, and operations)

Answers

Answer:

y = 3x

Step-by-step explanation:

Since, line given in the graph passes through origin (0, 0), relation between the number of tennis balls (y) and the number of cans (x) will be proportional.

y ∝ x

y = kx

Here 'k' = proportionality constant

Since the given line is passing through (1, 3),

3 = k(1)

k = 3

Therefore, equation of the line will be,

y = 3x

Answer:

56, 48, 44

Step-by-step explanation:

Since we have the players' probabilities, we simply need to take 80 free throws times their percentages.

80 x 0.7= 56

80 x 0.6 = 48

80 x 0.55 = 44

Find each unknown number.
a. 12 is 150% of what number?
b. 5 is 50% of what number?
c. 10% of what number is 300?
d. 5% of what number is 72?
e. 20 is 80% of what number?

Answers

A. 8
B. 10
C. 3,000
D. 1,440
E. 16

The required solution of the given percentages is as follows,
a.12 is 150% of 8.

b. 5 is 50% of 10.

c. 300 is 10% of 3000.

d.72 is 5% of 144.

e. 20 is 80% of 400.

What is the percentage?

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

here,
a. To find the number that 12 is 150% of, we can set up a proportion:

12 = 150% of x

We can convert 150% to a decimal by dividing by 100:

12 = 1.5x

Dividing both sides by 1.5 gives:

x = 8

Therefore, 12 is 150% of 8.

Similarly,
b. 5 is 50% of 10.

c. 300 is 10% of 3000.

d.72 is 5% of 144.

e. 20 is 80% of 400.

write the equation for the given information slope: -11, point (-1,20)​

Answers

Answer:

y = -11x + 9

Step-by-step explanation:

m = -11

x = -1

y = 20

Plug those values into the equation to find b: y = mx + b

20 = (-11)(-1) + b

---> b = 9

Plus m = -11 and b = 9 into y = mx + b

---> y = -11x + 9
