How much money would Madison make if her "proofreading" money was 20% less than what she was making (remember she used to get $1
1 answer:
Step-by-step explanation:
Part (a):
Since new payment amount is 20% less than the original, we can write
New Earning = N = $18 - (20%) ($18)
N = (80%)($18)
N = 0.8 * 18
N = $14.4
Part (b):
New number of errors are one-third () of the initial 15 errors,
Therefore, new number of errors = E =
E =
E = 5
It is given that, earnings per error = n = 15 cents = $0.15
Thus, we can calculate the total earnings for new number of errors as follows,
New Total Earning = N = n * E
N = 0.15 * 5
N = $0.75

Answer:
Step-by-step explanation:
If we have that worded expression, we can convert it into actual mathematical terms.
x to the one sixth power:
That to the power of 3:
Using exponent rules, since we have a power to a power, the powers multiply, so:
If we have a number to a fraction power, the denominator becomes the “find the (denominator) root of x.

Answer:
3.08 km/h.
Step-by-step explanation:
We know that,
Ali traveled at a speed of s km/h for 2.5 hours.
Let d be the distance and t be the time.
...(1)
On his return journey, he increased his speed by 4 km/h and saved 15 minutes. So, distance is d and times is t-15.
...(2)
From (1) and (2), we get
Put t=40 in (1).
So, t=40 and d=100.
Now,
Total distance = d + d = 100 + 100 = 200
Total time = t + t - 15 = 40 + 40 - 15 = 65
So, the average speed is
Therefore, the average speed is 3.08 km/h.
