Answer:
x = 16.8
Step-by-step explanation:
To get the value of x, we use Pythagoras’ theorem since what we have is a right angled triangle
Mathematically, we have it that;
the square of the hypotenuse (21) equals the sum of the squares of the two other sides
21^2 = 12.6^2 + x^2
x^2 = 21^2 - 12.6^2
x^2 = 282.24
x = √282.24)
x = 16.8
Answer:
120
Step-by-step explanation:
We let N be such that
9N = number pear juice bottles,
1N = number of pineapple juice bottles,
2N = number of grapefruit juice bottles.
Then, 20 = 2N, so that N = 10, and
The total number of juice bottles =
9N+1N+2N =
9(10)+1(10)+2(10)=
90+10+20=120
C, because when you add 45 on both sides, and then after that when you have to subtract 15 in both sides, you get 0 = 120.
C= 2pi
15= diameter. Radius= 15/2. R= 7.5
C= 2 times pi times 7.2
C=15 pi
C= 47.1
