D= difference in height
A= Alex's height (1.6m) N= Noah's height (1.5A)
Step 1:
D=N-A
substitute N= 1.5 A in for N
D= 1.5(1.6) - 1.6
D= 2.4 - 1.6
D= 0.8 m difference in height
Step 2:
Convert meters to centimeters 1 m = 100 centimeters
0.8 x 100-80cm
Noah is 80cm taller than Alex.
Hope this helps! :)
It is D because every time there is a box in the corner it's a right angle and they are always 90°
Answer:
4,800
Step-by-step explanation:
(14,700- 1,500) / 2 h 45 m
= 13,200 / 2.75
= 4,800 L/h
Answer:
The car drove for 1,024 miles.
Step-by-step explanation:
x=miles driven
y=days driven
448.76=29x+0.24y
448.76=29(7)+0.24y
448.76=203+0.24y
245.76=0.24y
y=1,024
Answer:
4*x^4*y^22
Step-by-step explanation:
Your goal here is to REDUCE the given expression to simplest terms.
One way in which to approach this problem would be to rewrite (2x^2y^10)^3 as: (2x^2*y^8)*y^2*(2x^2*y^10)^2.
Dividing this rewritten expression by 2x^2*y^8 results in:
y^2(2x^2*y^10)^2.
We now need to raise (2x^2*y^10) to the power 2. Doing this, we get:
4x^4*y^20.
Multiply this by y^2 (see above):
y^2*4x^4*y^20
The first factor is 4: 4y^2*x^4*y^20. This is followed by the product of y^2 and y^20: 4*y^22*x^4
Finally, this should be re-written as
4*x^4*y^22
Another way of doing this problem would involve expanding the numerator fully and then cancelling out like factors:
8*x^6*y^30 4*x^4*y^22
----------------- = ------------------ = 4*x^4*y^22
2x^2y^8 1
