a) Windows on the International Space Station are shown below. Suppose the long base of the window is 15.2 feet and the short base is 11.2 feet. The perpendicular height from one base to the other base is 8.4 feet. Draw one of the trapezoid-shaped windows on grid paper and label its dimensions. Describe the process you would use to find the area of one trapezoid-shaped window. (2 points)

Area of trapezoids = (base 1 + base 2) × (height ÷ 2)

(15.2 + 11.2) × (8.4 ÷ 2) = 110.88

The area is 110.88 feet²

b) Calculate the area of the window using the dimensions given in Part A. Show your work and explain your reasoning. (4 points)

Answers

Answer 1

Answer:

Step-by-step explanation:

Area of trapezoids = (base 1 + base 2) × (height ÷ 2)

(15.2 + 11.2) × (8.4 ÷ 2) = 110.88

The area is 110.88 feet²

2⅕ ÷ ⅗ = 11/3 or 3⅔

Step-by-step explanation:

2⅕ ÷ ⅗

= 11/5 (2*5+1) ÷ ⅗

= 11/5 × 5/3 (flip the fraction)

= [tex]\frac{11*5}{5*3}[/tex]

= 55/15 → 11/3 (divided by 5) or 3⅔

Which graph shows the solution to the system of linear equations?

y equals one third x

x + 3y = −6

Answers

Answer:So let's start by guesstimating the slopes:

the green line has a slope close to -x, but more negative than that, possibly -2; the pink line has a slope close to +x, but higher towards +2.

Next let's look at the solution: the two lines intersect at the point (1, -1).

**you could just simple plug that x (1) into all the equations, but let's rule out answers anyway. ;)

A) is incorrect because the slopes of -1 and +1 are off from out predicted -2 and +2

B) is incorrect because of a similar reason, the slopes of +3 and +1 don't make any sense

C) Ooh, we do have a +2 and -2 for the slopes, and... violà! plug in 1 for the x's and we get -1 for the y in both equations

D) slopes are closer than in A and B, but plugging in 1 doesn't get us -1

So the correct answer is:

C) y = 2x - 3 and y = −2x + 1

Rewrite the expressions without the absolute value sign.

|x+12| , if x>−11

Answers

If x< -5 then x+5 < 0
but the absolute value of x+5 > 0

X+12 >-11
X> -23
But also you have to write a second equation to get both possible answers for x since it was in absolute value
X+12>11
X>-1
So x > -23, -1

Answer is y=6x

Explanation

When you have a graph, you can find the slope or coefficient next to x, by finding rise over run on the graph or using slope formula.

On the graph, from 0, 0, we go up or rise +6 and go right or run +1. Slope is 6/1 or 6.

Or, you have (0, 0) and (1, 6) as two definite points. Using slope formula
y2 - y1 over x2 - x1

6 - 0 over 1 - 0 = 6/1 or slope of 6.

Y=6x I think. Have a good day
