It will take her 8 weeks to have enough money for a bike. I made the equation 125+15x=245 and multiplied 15 by 8 to get exactly 245
The third one :) I hope I did it right
So you can you the Pythagorean theorem to solve this problem.
if each side of the square is a certain length x, then the square is made up of two right triangles.
the sides adjacent to the right angle are length x while the hypoteneus is the diagonal whcih measures 36 feet.
a^2 + b^2 = c^2
x^2 + x^2 = 36^2
2x^2 = 1296
x^2 = 648
x = 25.456
area of a square = x^2 = 648 ft^2
Answer:
the answer is 6.75
Step-by-step explanation:
12 x 5 = 60 60 = 1 hour so 1.35 x 5 = 6.75
Answer with Step-by-step explanation:
We are given that
a.Radius =25 m
We have to find rate of change of radius.
We know that
Area of circle,
Differentiate w.r.t time
Substitute the values then we get
b.A=
Substitute the values then we get
Substitute the values then we get
m/s
m/s
