if a lady chargers $2.00 for gas and $3.00 per 1/2 hour of work . What is the amount of money she makes in 4 hours ?

anastassius [24]

Answer:

$32

Step-by-step explanation:

The lady charges $2.00 for gas which means over a 4 hour period we would do

4 x 2 = 8

She makes a total of 8 dollars

She also gains $3.00 per half hour of work

This means we would do 3 x 8

We add these values to get $32

The area of a circle is 28.26 square centimeters. What is its diameter (use 3.14 for ð)?

horsena [70]

Area for circle is πr² so πr² =28.26 and we can sub 3.14 as pi
3.14*r²=28.26 we can divide by 3.14 to get r² on it's own
r²=28.26/3.14
then we root both sides to get r on it's own
28.26/3.14=9 √9=3
and the diameter is double the radius 3*2=6 so the diameter is 6

A rectangular board has an area of 648 square centimeters. The triangular part of the board has an area of 162 square centimeter

maksim [4K]

Answer:

25%.

Step-by-step explanation:

Let E be the event that the dart lands inside the triangle.

We have been given that a rectangular board has an area of 648 square centimeters. The triangular part of the board has an area of 162 square centimeters.

We know that probability of an event represents the chance that an event will happen.

$\text{Probability}=\frac{\text{Favorable no. of events}}{\text{Total number of possible outcomes}}$
