Answer:

Step-by-step explanation:

First, we'll need to find the other angle of the triangle. To do this, we'll add 32 and 107 together to get 139.

After this, we'll do 180-139 to get 41, which is our answer.

Remember: A straight line angle is always equal to 180.

Suppose y varies inversely with X, and y = 48 when x = 3. What is the value of x when y = 24?

olganol [36]

Answer:

C. 6

Step-by-step explanation:

Recall that inverse variation is given by:

$\displaystyle y=\frac{k}{x}$

Where k is the constant of variation.

We know that y = 48 when x = 3. Substitute:

$\displaystyle (48)=\frac{k}{(3)}$

Solve for k:

$k=3(48)=144$

Hence, our equation is:

$\displaystyle y=\frac{144}{x}$

We want to find x when y = 24. Substitute:

$\displaystyle \frac{24}{1}=\frac{144}{x}$

Cross-multiply:

$24x=144$

Divide both sides by 24. Hence:

$x=6$

Our answer is C.

A: x/8=3/4 B: 2/5=x/40 C: 1/8=x/40 D:x/10=12/15

Aloiza [94]

I’m assuming you want to figure out what x is in the equation so....

6/8=3/4
2/5=16/40
1/8=5/40
8/10=12/15

I hope this helps.
