Answer:

706.4ft²

Step-by-step explanation:

This is a prism with a trapezoid base. The total area includes:

1) 2 trapezoids (bases):

A1=2×(19+5)×12.1/2=24×12.1=290.4ft²

2) side area:

A2=base perimeter×prism height=

(19+5+14+14)×8=(24+28)×8=52×8=416ft²

So total area is A1+A2

A=290.4+416=706.4ft²

Terri wrote the equation using slope-intercept form for the line that passes through the points (4, 6) and (–2, 3).
oksano4ka [1.4K]

Answer:

y=0.5x+4

Use y2-y1/x2-x1 to find the slope:

3-6/-2-4

Sub in the x and y-values into y=0.5x+b

6=0.5(4)+b

Solve and b=4

How many natural numbers?<br> from 78 to 234<br> how many whole numbers <br> from 24 to 721
Vinil7 [7]

Answer:

<u>158 natural numbers from 78 to 234, and 699 whole numbers from 24 to 721.</u>

Step-by-step explanation:

Natural numbers are positive integers (whole numbers), so all numbers from the range of 78 to 234 would be included, including 78 and 234 itself. That is 158 natural numbers. Whole numbers are numbers without a fraction or decimal, they are integers. So all numbers from 24 to 721 would be included, as well as 24 and 721 itself. That is 699 whole numbers from 24 to 721. Hope this helps.

Name the slope and one point that is on the line
Alekssandra [29.7K]

Answer: Choice A

m = undefined

point (-2,5)

==================================================

Explanation:

The equation x = -2 describes a vertical line in which every point on this line has x coordinate -2. Two points on this line are (-2,0) and (-2,1)

Another point on this line is (-2,5) since this also has x coordinate -2.

------------------

All vertical lines have undefined slope.

Let's pick two points such as (-2,0) and (-2,1) and find the slope through them

m = (y2-y1)/(x2-x1)

m = (1-0)/(-2-(-2))

m = (1-0)/(-2+2)

m = 1/0

m = undefined, since we cannot divide by zero.
