The length of a rectangle is 4 more than the width. If the perimeter is 36 inches, what’s the width and length of the rectangle?

Answers

Answer 1

Answer:

7 inches

Step-by-step explanation:

Answer 2

Answer:

The width and the length of the rectangle is...

Step-by-step explanation:

If we are looking at the total Perimeter of the rectangle, which is 36 inches, then we have to take in the information of the '4 more than the width'. so we need to think of the numbers that would make sense in this scenario. the formula to solve this would be:

w + (l + 4 ) x 2 = 36

So we would need to look at the different scenarios that don't go over 18.

if the width = 7

and the length = 11

7 + 11 = 18

18 x 2 = 36.

In softball, Marissa hits the ball 40% of the time when she is up to bat. Based on this information, how many times will Marissa hit the ball if she goes to bat 30 times?

Answers

Answer:

Marissa hit the ball 12 times if she goes to bat 30 times.

Step-by-step explanation:

Given that:

Marissa hits the ball 40% of the time when she is up to bat.

Marissa gets to bat for 30 times.

Balls hit by Marissa = 40% of the times Marissa goes to bat

Balls hit by Marissa = [tex]\frac{40}{100}*30[/tex]

Balls hit by Marissa = 0.4 * 30

Balls hit by Marissa = 12

Hence,

Marissa hit the ball 12 times if she goes to bat 30 times.

Write an equation in point-slope form of the line that passes through the point (2,−8) and has a slope of 4.

Answers

Answer:

y = 4x - 16

Step-by-step explanation:

Plug in the slope and point into y = mx + b, and solve for b:

y = mx + b

-8 = 4(2) + b

-8 = 8 + b

-16 = b

Then, plug in b and the slope into y = mx + b

y = 4x - 16 is the equation in point slope form

what are some real world limitations to the domain and range of both functions?​

Answers

Answer:

See below

Step-by-step explanation:

Uber$5 pickup fee$0.25 per mile

Equation

y = 0.25x + 5

Cost of 5 miles:

y = 0.25(5) + 5 = $6.25KC yellow Cab Co.$1.75 pickup fee$0.75 per mile

Equation

y = 0.75x + 1.75

Cost of 5 miles:

y = 0.75(5) + 1.75 = $5.5

Comparing the cost we see KC yellow Cab Co. is better value for a 5 mile ride.
