Answer:
a person travel 50 ft from the bottom to the top of the escalator
Step-by-step explanation:
An escalator lifts people to the second floor of a building, 25 ft above the first floor. The escalator rises at a 30 degree angle
The escalator forms a right angle triangle
opposite to 30 degree angle is 25 feet. to find the distance from the bottom to the top of the escalator we find the hypotenuse
let x be the hypotenuse
a person travel 50 ft from the bottom to the top of the escalator
Answer:
Step-by-step explanation:
← Equation 1
By simplifying the above equation we get,
(Simplifying the brackets)
(By subtracting 
from 
) ← Equation 2
Multiply Equation 1 by 5 and Equation 2 by 3 and add them together.
Equation 1 multiplied by 5 will give,
Equation 2 multiplied by 3 will give,
Add those together,
(After simplifying 
values)
Therefor
By substituting to Equation 1 we get,
Therefor we can say,
Answer:
Step-by-step explanation:
-2⁶ = -(2⁶) = -(64) = -64
(-2)×(-2)×(-2)×(-2)×(-2)×(-2) = (-2)⁶ = (-1⋅2)⁶ = (-1)⁶⋅2⁶ = 1⁶⋅2⁶ = 64
I think 100% profit means she got the gloves for free so all her revenue was profit. That can't be right. Let's assume 'profit on the cost' means a 100% markup, meaning she sold the gloves for £8.
That means she sold the skirt for £40.
She made 20% profit on the total cost t so
1.2 t = 48
t = 48/1.2 = 40
Since she spent £4 on the gloves that means she spent £36 on the skirt she sold for £40.
So she made £4 on a cost of £36 for a percentage of 1/9=.11111...
Answer: 11.1%
