Answer:

Step-by-step explanation:

1. Cost of each notebook = 3.79

Cost of 8 notebooks = 3.79 x 8 = 30.32

Amount gave to cashier = 50

Change = 50 - 30.32 = 19.68

What’s the distance ?
Aleksandr [31]

Answer:

3

Step-by-step explanation:

This problem asks one to find the length of the given line. Another way to think about this problem is to believe that the problem asks one to find the distance from one point to another. The endpoints on this line are the following,

(4,2), (5, 5)

The formula to find the distance between two points on a 2-dimensional coordinate plane is as follows,

D=\sqrt{(x_1-x_2)^2*(y_1-y_2)^2}

Substitute the endpoints of the line into the formula and solve for the distance between the points,

D=\sqrt{(4-5)^2*(2-5)^2}

Simplify, solve for the distance between the two points,

D=\sqrt{(4-5)^2*(2-5)^2}

D=\sqrt{(-1)^2*(-3)^2}\\\\D=\sqrt{1*9}\\\\D=\sqrt{9}\\\\D=3

stellarik [79]

Answer:

y-intercept is the weight of the animal at birth (when x = 0)

Step-by-step explanation:

y=3.86x+15

The slope (gradient) of the function is 3.86

The y-intercept of the function is 15

Therefore, the y-intercept is the weight of the animal at birth (when x = 0)

Evaluate function f(x) = 5x - 3 f(5) =
zhenek [66]

Answer:

f(5) = 22

Step-by-step explanation:

When we want to solve for f(x) = 5x - 3 when x is 5, all we have to do is plug in 5 as x into the equation.

f(x) = 5x - 3

f(5) = 5(5) - 3

5 * 5 = 25

25 - 3 = 22

f(5) = 22

I hope this helps you!

Answer:

314.159265

Step-by-step explanation:

Area = pi(r)^2

Since radius isn’t identified diameter must be divided in half

radius = 10

Area = pi(10)^2

Multiply 10 x 10

10 x 10 = 100

Area = pi(100)

Multiply 100 by pi

pi x 100 = 314.159265
