The ratio 14:30 does not describe Rita's class.

The ratio that would describe Rita's class can be shown here:

14:16 = 7:8

Step-by-step explanation:

Let alpha be the unknown angle. We can set up our sine law as follows:

$\frac{ \sin( \alpha ) }{5 \: m} = \frac{ \sin(42) }{3.6 \: m }$

$\sin( \alpha ) = \frac{5 \: m}{3.6 \: m} \times \sin(42) = 0.929$

Solving for alpha,

$\alpha = arcsin(0.929) = 68 \: degrees$

Mel received notice that his monthly health care rate will increase 20% next year. If Mel currently pays $150 per month for heal

sveta [45]

It will increase by $30

We need to convert the percentage to a decimal by dividing by 100. Then we multiply by the $150.

150 x 0.20 = 30

Would appreciate some help with this question, I am struggling!

I think you would multiply 14m x 9m which is 126m and then you would multiply 2.4m and 3.8m which is 9.12m. Last you would subtract 9.12m from 126m which is 116.88m...I’m sry if this isn’t correct

Answer:

Step-by-step explanation:

They are the same angle so they must be equal.

So, x+5 = 2x-7

5+7 = 2x-x

12 = x

20/50 = 30/x solve for x

alex41 [277]

Answer:

x = 75

Step-by-step explanation:

20/50 = 30/x

Divide the numbers and find x. If you plug back in 75 for x and simply, you should get the same fraction for each, 4/10.
