answer as soon as possible, please! !algebra! 2¹⁵ x 8¹⁹ x 2⁴ x 8¹⁰ a. 2¹⁹ x 8²⁹ b. 4⁶⁰ x 64¹⁹⁰ c. 2⁶⁰ x 8¹⁹⁰ d. 4¹⁹ x 16²⁹ and the x's are multiplication not variables

The measure of angle B would be 100°

Step-by-step explanation:

Supplementary means two angles add up to 180 degrees. Let's say A+B=180. Since we know what A is, we can substitute that in, B+80=180. Now solve. B=100

Step-by-step explanation:

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
