Answer:
7.
Step-by-step explanation:
7^8 x 7^3 x 7^4 / 7^9 7^5
= 7^(8+3+4) / 7^(9+5)
= 7^15 / 7^14
= 7^(15-14)
= 7.
Answer:
12 x 8 divided by 2 = 48cm
Step-by-step explanation:
0.4^3 = 0.4 · 0.4 · 0.4 = 0.064
Write the formula: A=a+b/2(h). Sub in what you know: 9=a+b/2(1). Divide by the height: 1: 9=a+b/2. Multiply by 2: 18=a+b. Now a is typically smaller than b so my guess would be a=6 b=12 but you could pick any numbers as long as they equal 18 :)
If you have two of the same digit next to each other in a number, such as 11, the digit on the left side is worth 10 times more than the digit on the right. (Therefor, the digit on the right side is worth 10 times less than the digit on the left.)
