To find Matthew's hourly rate, you would divide $102 by 8.5. His hourly rate is $12. Then multiply by 19 hours, and the answer is $228.

The number a is smaller than the number b by 1/5 of b. By what part of a is b bigger than a?
Ira Lisetskai [31]

Answer:

The number b is bigger than the number a by \dfrac{1}{4} of a.

Step-by-step explanation:

1. If the number a is smaller than the number b by 1/5 of b, then

a+\dfrac{1}{5}b=b.

Thus,

a=b-\dfrac{1}{5}b=\dfrac{4}{5}b,\\ \\b=\dfrac{5}{4}a.

2. Consider the expression b=\dfrac{5}{4}a:

b=\dfrac{5}{4}a=\dfrac{4}{4}a+\dfrac{1}{4}a=a+\dfrac{1}{4}a.

This gives you that the number b is bigger than the number a by \dfrac{1}{4} of a.

Over which interval are the exponential and linear function approximately the same? from 0.25 to 0.5 from 0.5 to 0.75 from 0.75
ryzh [129]

Answer:

Answer is 0.25 to 0.5

Step-by-step explanation:

Let the linear function be y=x

and exponential function be y=e^x

x          0.25   0.5    0.75    1.0     1.25    1.5

y          0.25   0.5    0.75    1.0     1.25    1.5

Diff             0.25  0.25  0.25   0.25  0.25

e^x      1.29   1.65    2.12     2.72  3.49    4.48

Diff            0.36  0.47     0.60   0.77    0.99

Hence 0.36 to be nearer to 0.25, than other intervals

So answer is 0.25 to 0.5
