Answer:

The answer would be the 1st one.

Step-by-step explanation:

When you use a percentage calculator or look it up, you can shay 40 as a percent of 19 and the answer will be 47.5%. You could also divide and get your answer that way as well.

Hope that helps! If you get it wrong, please tell me so I could check my work.  Have a great rest of your day :)!

Answer:

x =12

Step-by-step explanation:

Since this is an isosceles triangle the angles at the bases of the equal sides are equal

The unmarked angle is 4x

The 3 angles of a triangle total 180 degrees

4x+4x+ 84 =180

Combine like terms

8x +84 = 180

Subtract 84 from each side

8x +84-84 = 180 -84

8x =96

Divide by 8

8x/8 = 96/8

x =12

Answer:

5

Step-by-step explanation:

(0.000064)^5/6 divided by (0.00032)^6/5

(0.00032)^6/5=(0.000064)

and

(0.000064)^6/5=(0.00032)

so now we have (0.00032) divided by (0.000064)

which is 5!

hope this helps!
