To help u out do this equation and understand it
Step-by-step explanation:
1. 17000 x 0.04 = ?
2. ? x 5 = The answer but not rounded
3. Round it
Just multiply the amount it takes to clean one shower by 5.
5 * 5.22 = 26.1
So it will take 26.1 minutes to clean all 5 showers.
Answer:
Step-by-step explanation:
We have been given that at a zoo, the lion pen has a ring-shaped sidewalk around it. The outer edge of the sidewalk is a circle with a radius of 11 m. The inner edge of the sidewalk is a circle with a radius of 9 m.
To find the area of the side walk we will subtract the area of inner edge of the side walk of lion pen from the area of the outer edge of the lion pen.
, where r represents radius of the circle.
Therefore, the exact area of the side walk is
To find the approximate area of side walk let us substitute pi equals 3.14.
Therefore, the approximate area of the side walk is .
Answer:
g^−1(7) = 6
h^−1(x) = x/2 + 3/2
(h^−1 ∘ h)(3) = 3
Step-by-step explanation:
If
g(6) = 7
Then
g^−1(7) = 6
h(x) = 2x - 3
Isolate x:
2x = h(x) + 3
x = h(x)/2 + 3/2
Replace x with h^−1(x) and h(x) with x:
h^−1(x) = x/2 + 3/2
We know that:
(h^−1 ∘ h)(x) = x
then:
(h^−1 ∘ h)(3) = 3
A similar triangle means it is of a diferent size, but the sides or angles are proportionaly the same.
Use the rule of 3 on each number, to find the equivalent sides:
65 - 39
60 - x
(60 * 39) / 65
2340 / 65
36cm
60 - 36
25 - x
(25*36) / 60
900 / 60
15cm
Original triangle: 65, 60, 25
Similar triangle: 39, 36, 15
