Show two ways to multiply 2/15 × 3/20. then tell which way is easier and justify your choice.

Answers

Answer 1

Answer: Well, 1 way is multiply the denominators like this 15×20=300. So use the 15 and multiply it with both of the numerators.

Step-by-step explanation:

x + 3y = 15

4x + 2y = 30

This system of equations can either be solved by elimination method or substitution method or both

We are going to use both method to solve this system of education

First we are gong to use elimination method to find the value of y

x + 3y = 15 -------------(1)

4x + 2y = 30 -----------(2)

Using the elimination method, to eliminate x, we want to make coefficients of x the same, to do that we multiply equation (1) by 4

4x + 12y =60 --------------(3)

subtract equation (2) from equation (3)

(4x-4x =0 12y - 2y = 10y 60 -30=30 )

We will have;

10y = 30

Divide 10 by both-side of the equation

10y/10 = 30/10

y = 3

We will use substitution method to get the value of x,

We will now substitute y=3 in equation (1)

x + 3y = 15

x + 3(3) = 15

x + 9 = 15

Subtract 9 from both-side of the equation

x +9 - 9 = 15 -9

x = 6

The solution to the system of the equations is x=6 and y =3

A movie theater offers popcorn in two different containers for the same price. One container is a trapezoidal prism with a base area of 34 square inches and a height of 5 inches. The other container is a triangular prism with a base area of 35 square inches and a height of 6 inches. Complete the explanation on which is a better deal:The (_trapezoidal or triangular__) prism is a better deal because you get ______ inches cubed for the same price you would pay for _______ inches cubed with a (_trapezoidal or triangular_) prism.

Answers

Given:
Trapezoidal prism: base area = 34 in² ; height = 5 in
Triangular prism: base area = 35 in² ; height = 6 in

Volume of Trapezoidal prism = base area * height
V = 34 in² x 5 in
V = 170 in³

Volume of Triangular prism = base area * height
V = 35 in² x 6 in
V = 210 in³

The TRIANGULAR prism is a better deal because you get 210 inches cubed for the same price you would pay for 170 inches cubed with a TRAPEZOIDAL prism.

What do i do if i have a problem like this x exponent 5 = 1024 and (-1/7) exponent -x = -1/343

Answers

x^5 = 1024 = 4^5
Therefore, x = 4.

Given, (-1/7)^-x = -1/343
(1/7)^-x = 1/343
(1/7)^-x = (1/7)^3
-x = 3
x = -3
