Answer:
9
Step-by-step explanation:
if z=8 then z^2 would be 64, which is not equal to 80
iz z=9 then z^2 would be 81, which is closer to 80 than 64
therefore, 9 is the whole number than z would be closest to
Answer:
45°
Step-by-step explanation:
The acute angles of a right triangle are complementary. The base angles of an isosceles triangle are congruent. If x is the measure of the base angles, this requires ...
x = 90-x . . . . . the base angle is congruent to the other base angle
2x = 90 . . . . . add x
x = 90/2 = 45 . . . . divide by 2
The measure of a base angle of an isosceles right triangle is 45°.

Solution :
It is given that four different prizes were awarded. So,
a). 4 ways for person 47 to win a prize
99 ways to give out the 2nd prize
98 ways to give the 3rd prize
97 ways to give the last prize
∴ P(99,3) = 99 x 98 x 97
b). 1 way to give person 47 their prize
1 way to give person 19 their prize
98 ways to give out the 3rd prize
97 ways to give out the last prize
So, P(98,2) = 98 x 97
9
Step-by-step explanation:
15x+12=19x-24
15x-19x=-24-12
-4x=-36/÷(-4)
x=9
You first put all the x on one side and numbers on the other and be careful about + and - and then you divide by everything with the x so you have only the x left and you get the aswer.
