Answer:
The value is 2401
Step-by-step explanation:
First we need to understand what's means 7 to the 4th power, or 7^4.
7 is the power base, the power base is the number that we are going to repeat the number of times the exponent says.
4 is the exponent, which will tell us how many times to multiply 7.
So , then we would have
1) 7 x 7 x 7 x 7
2) 49 x 7 x 7
3) 343 x 7
4) finally 2401
Answer:
D = 20H
Step-by-step explanation:
The amount Troy (D, in dollars) charges to mow a lawn is proportional to the time (H, in hours) it takes him to mow the lawn.
Hence, we can write D = kH ......... (1), where k is a constant.
Now, given that Troy charges $30 to mow a lawn that took him 1.5 hours to mow.
So, from equation (1) we get
30 = 1.5k
⇒ k = 20.
Therefore, equation (1) becomes D = 20H (Answer)
