Answer:

Perimeter of rectangle is 72 feet.

Step-by-step explanation:

We need to find the perimeter of rectangle where

Length = 21 feet

Width = 15 feet are given.

The formula used will be: Perimeter of rectangle = 2(Length + Width)

So, Perimeter of rectangle is:

Perimeter of rectangle = 2(Length + Width)

                                      = 2 ( 21+15)

                                      = 2(36)

                                      = 72 feet.

So, perimeter of rectangle is 72 feet.

2*(l+b)

So,

2*(21+15)

2*36

=72

Answer:

A. There is no solution. For the inequality to be true, the value of x has to be negative. This is impossible because Wilmer can't have a negative number of Reading Response assignments.

Solve x in the diagram below
zzz [600]

A straight line is 180°, so you add these two angles together because they make a straight line:

3x° + 75° = 180°        

To find "x", isolate/get the variable "x" by itself in the equation. Subtract 75° on both sides

3x° + 75° - 75° = 180° - 75°

3x° = 105°      Divide 3 on both sides to get "x" by itself

x = 35°

PROOF

3x° + 75° = 180°   Substitute/plug in 35 into "x" since x = 35°

3(35)° + 75° = 180°

105° + 75° = 180°

180° = 180°

<u>Since half of the numbers are even, 2, 4, 6</u>

  • P(even) = 3/6 = 1/2

#2

<u>Multiple of 3 are 3 and 6:</u>

  • P(multiple of 3) = 2/6 = 1/3

#3

<u>The numbers ≤ 4 are: 1, 2, 3, 4</u>

  • P(≤4) = 4/6 = 2/3

#4

<u>Prime numbers are 2, 3, 5</u>

  • P(prime) = 3/6 = 1/2

#5

<u>Numbers > 1 are 2, 3, 4, 5, 6</u>

  • P(>1) = 5/6

#6

<u>A four, there is one option</u>

  • P(4) = 1/6
