Answer:
this question is very hard
Step-by-step explanation:
Answer:
If you keep adding a zero and keep getting the same number again and again. Than what you have is a repeating decimal.
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.

Answer:
The area of figure is 420 000 ft².
Step-by-step explanation:
You can seperate the diagram into 2 parts, top is trapezium and bottom is rectangle. Then you have to use the formula for each part :
Trapezium,
Let a = 600 ft,
Let b = 900 ft,
Let height = 200 ft,
Rectangle,
Let base = 900 ft,
Let height = 300 ft,
Lastly, you have add both areas together :
For this equation first you should add +11 on both sides and the add -4/7w so you will have:
3/7w- 4/7w = 11 ⇒ -1/7w = 11 ⇒ w = 11* -7 = -77 so the answer is:
w = -77 :)))
