A Rectangle Has A Perimeter Of 68 Inches.if The Width Of The Rectangle Is 10 Inches,what Is The Length

Answers

Answer 1

Answer:

l=24in

Step-by-step explanation:

P=2(l+w)

l=P

2﹣w=68

2﹣10=24in

Answer 2
24 inches because if you add the two width you get 20 and then do the equation 68-20=48. Divide that by 2 and then you get 24 so then that’s the length

Find the value of x.

Answers

x + 3x + 48 = 180
4x + 48 = 180
subtract 48 from both sides
4x = 132

According to the graph, what is the approximate average rate of change in the radius of the circle as the area increases from 3 square feet to 7 square feet?

Answers

Answer:

0.5

Step-by-step explanation:

At 3, the radius was about 1. At 7 it was about 1.5. Giving us a difference of 0.5.

I might be wrong

The approximate average rate of change in the radius of the circle as the area increases from 3 square feet to 7 square feet is 0.125 foot per square foot

What is rate of change?

The rate of change formula gives the relationship describing how one quantity changes in relation to the change in another quantity. The rate of change from the coordinates of y to coordinates of x can found out as

rate of change =  [tex]\frac{Change in y}{Change in x} =\frac{(y2 - y1 )}{(x2 - x1 )}[/tex]

According to the question

The area increases from 3 square feet to 7 square feet

i.e, Change in x = 7-3

                         = 4 square feet

Between  area increases from 3 square feet to 7 square feet  radius changes form 1 to 1.5 feet

i.e, Change in y = 1.5 - 1

                          =  0.5 feet

As,

rate of change =  [tex]\frac{Change in y}{Change in x} =\frac{(y2 - y1 )}{(x2 - x1 )}[/tex]

substituting the values

rate of change = [tex]\frac{0.5}{4}[/tex]

                          = 0.125 foot per square foot

Hence, the approximate average rate of change in the radius of the circle as the area increases from 3 square feet to 7 square feet is 0.125 foot per square foot

Answers

Answer: I think it is vertical

Step-by-step explanation:

Answer:

vertical, x=25

Step-by-step explanation:

The angles are vertical angles and vertical angles are equal

75 = 4x-25

Add 25 to each side

75+25 = 4x-25+25

100 = 4x

Divide each side by 4

No of total brown = 2 + 1 = 3 .
probability = 3 / 6
= 1 /2 .
no of males = 2
probability
= 2 / 6
= 1 /3
no of person who is both male and brown = 1
probability = 1 /6
Required probability
= probability of being brown + probability of being male - probability of being both
= 1 / 2 + 1 / 3 - 1 /6
= 4 / 6
= 2 / 3 .
