Answer:

The temperature in degrees Celsius is -48°C .

Step-by-step explanation:

The given equation is:

v = 20√[t + 273]

Therefore, rearranging we get:

(v / 20)² = t + 273

t = (v / 20)² - 273

but the speed of sound, v, is equal to 300 m/s

Therefore,

t = (300 / 20)² - 273

t = -48°C

Therefore, the temperature in degrees Celsius is -48°C .

Answer:

7.3

Step-by-step explanation:

The two triangles are similar, meaning that they have the same angles but the triangles are in different sizes. To solve this, use proportions:

$\frac{3}{5} =\frac{4.5}{x}$

Cross multiply:

$3x=22.5\\x=7.3$

Answer: 3
Step by step explanation: If there are 60 kids and 25% of them went to Floridia, then 1/4 of them went to Floridia, which is 15 (Bc 60/4=15). If 20% of them went to NY, then that’s 1/5 if the the kids, which is 12 (Bc 60/5=12). Finally, you just subtract 15 from 12 and get 3. Hope that helps!

You set up the problem correctly, just keep going.

Expand out your expression:

2x(3x-9) + 4x(x+13)
= 6x^2 -18x + 4x^2 + 52x
= 10x^2 +34x

Remember that the above expression is the area, so it is equal to 24.

10x^2 + 34x = 24
10x^2 + 34x - 24 = 0 (divide by 2)
5x^2 + 17x - 12 = 0

Done.
