Answer:

Step-by-step explanation:

We are given the expression [tex][(\frac{3}{5})^0]^{-2}[/tex] and are asked to find the value of it.

To solve this, we can use the exponent rule of multiplying the exponent inside of the parenthesis with the one outside of the parenthesis.

[tex](a^b)^c = a^{bc}[/tex]

[tex](\frac{3}{5})^{0*-2}[/tex]

[tex]\frac{3}{5}^0[/tex]

Anything with an exponent of zero equals 1. Therefore :

[tex]\frac{3}{5}^0 = 1[/tex]

60x + 75 :))

Explanation: were disrupting 15 to 4 & 5 so were multiplying because when a number is in  parenthesis like this a(b) we multiply.

Answer:

60x + 75

Step-by-step explanation:

When using distributive property, multiply the number on the outside of the parenthesis by the numbers on the inside of the parenthesis.

Here, the number outside of the parenthesis is 15.

15 (4x + 5)

15 ⋅ 4x = 60x

15 ⋅ 5 = 75

KEEP WHICHEVER SIGN IS IN THE MIDDLE OF THE PARENTHESIS.

15 (4x + 5) = 60x + 75

A. 2

B. 3

C. 4

D. 5

E. 6

Answers

Answer:

E.6, mark the guy above me brainliest, they got it right and answered first.

Jimmy would need 6 cubic blocks with a side length of 1/2 yard to measure the volume of his trunk.

Option E is the correct answer.

What is a prism?

A prism is a three-dimensional object.

There are triangular prism and rectangular prism.

We have,

The volume of the cedar trunk is 3/4 cubic yard.

To find the number of cubic blocks with a side length of 1/2 yard, we can divide the volume of the trunk by the volume of each cubic block:

So,

(3/4 cubic yard) ÷ (1/2 yard)³

= (3/4 cubic yard) ÷ (1/8 cubic yard)

= 6 cubic blocks

Therefore,

Jimmy would need 6 cubic blocks with a side length of 1/2 yard to measure the volume of his trunk.

A tributary joins a river at an angle. Find the value of x.
WhAt this is- just- uGh

Answers

Answer:

x = 53

Step-by-step explanation:

I'm going to assume that this is just a real-life scenario of two lines intersecting to create two adjacent angles that are also a linear pair. So, the following equation can be set up to solve for x.

x + 2x + 21 = 180

3x + 21 = 180

3x = 159

x = 53

Time to check.

53 + 2(53) + 21 = 180

53 + 106 + 21 = 180 It works!

Answer:

x = 53º

Step-by-step explanation:

The two angles form a supplementary angle, telling us that the sum of the two equal 180º, allowing us to form one side of the equation.

2x + 21 + x = 180

+x

3x + 21 = 180

     -21     -21

3x = 159

159/3 = 53

x = 53º

(also I know it doesn't say you have to find the value of each angle but just in case lol)

Now that we have x, the first angle equals 53º. Just plug in 53 to the other side

2(53) + 21

106 + 21 = 127

just to check, 127 + 53 = 180
