suter [353]

Answer: 10%

Explanation:

Given: Previous Hourly pay= $7.00

Current Hourly pay = $7.70

Increase in hourly pay = Current Hourly pay - Previous Hourly pay

= $7.70- $7.00

= $0.70

Now, the percent increase in her hourly rate of pay will be :

$\dfrac{\text{Increase in hourly pay}}{\text{Previous Hourly pay}}\times100\%\\\\=\dfrac{0.70}{7}\times100\%\\\\=\dfrac{1}{10}\times100\%\\\\=10\%$

Hence, the percent increase in her hourly rate of pay = 10%

Is atmospheric pressure the same everywhere on the surface of the earth?

vitfil [10]

Answer:

Atmospheric pressure differs in different parts of the world.

Explanation:

This is because atmospheric pressure depends on the height of a particular location on earth.
A number of locations on the earth are at sea level. The atmospheric pressure at sea level is 14.7 pounds per square inch.
At higher levels (altitudes) the atmospheric pressure is lower since higher places have got less air pushing downwards compared to lower altitudes which have more air pushing down and hence, high atmospheric pressure.

Papessa [141]

The slope means : A.

the increase in the number of pounds a boy gains each year

Explanation:

Given the equation for line of best fit as : y=1.73x +80.13

At the age of 5 the weight will be;

x=5, y= 1.73*5+80.13 =88.75 pounds

At the age of 6, the weight will be;

x=6, y=1.73*6+80.13 = 90.15

Difference in weight after one year increase of age will be;

90.15-88.75=1.73

This means after a year, a boy gains 1.73 pounds
