2. He can break his strand of 10 blocks into 3 3 times 4. I think it is 74 blocks are needed.
Answer:
823.7 m^2
Step-by-step explanation:
The ratio of the side lengths is 6/5.
The ratio of the areas is the square of the ratio of the side lengths, 36/25.
572 m^2 * 36/25 = 823.7 m^2
Answer:
y = 2x - 7
Step-by-step explanation:
Looks like we already have the slope of this line: It is 2. Working with the point (1, -5), we have x = 1 and y = -5 and can from this info easily find the y-intercept, b:
y = mx + b becomes
y = 2x + b, which in turn becomes
-5 = 2(1) + b, or
b = -7,
and so the desired equation is y = 2x - 7
Answer:
3
Step-by-step explanation:
Again, anything to the 0th power is equal to 1.
The 0th power is attached to the b, so this means that b = 1. Multiply 9 and (1) together to get 9.
Now you can subtract 9 from 12 to get 3 as your final answer.
