6. A two-story building measures 21 feet from

Mathematics
1 answer:
Andru [333]2 years ago

Answer:

12 inches

Step-by-step explanation:

To solve you have to set up a ratio. Because both buildings are being shrunk the exact same amount, you just have to account for the size difference from the miniature and real life. The ratio is 21:3 and 84:x. To find x you just have to cross multiply and solve.

The equation comes out to be 252 = 21x

Divide both sides by 21 to get x.

252/21 = 12

The size of the 84 foot building as a model is 12 inches.

If y = kx, what is the value of k if y = 20 and x = 0.4? A) 5 B) 8 C) 9.6 D) 50
Margaret [11]
Answer: D, 50
y = kx          <span>y = 20 and x = 0.4
</span>
What you will do: You will plug in your y and your x.
Your equation should look like: 20=k(0.4)
Next: What you will do is divide each side of your equal sign by 0.4 so you will get your k alone.
You would get: k=50

HOPE THIS HELPS! ^_^

Yes! That's exactly right.

8x-1+58+75=180

8x+132=180

8x=48

x=6 degrees

An isosceles triangle has an angle that measures 92° which other angles could be in that isosceles triangle choose all that appl
nignag [31]

Answer:

44

Step-by-step explanation:

The two base angles cannot both be 92 degrees because they would add up to 184 which is more degrees than any triangle has. The apex angle (the top angle) therefore has 92 degrees.

The base angles are equal and found as follows.

2*b + 92 = 180                 Subtract 92 from both sides

2b +92-92 = 180-92

2b = 88                           divide by 2

2b/2=88/2

b = 44

The only angle measurement that fits is 44
