Answer:

1) 5.75

2) -6.25

3) 3.75

4) -3.5

5) decreased by 3.3 gallons

Step-by-step explanation:

1) 8 - 2.25 = 5.25

2) - 3\frac{1}{2}  + (  - 2\frac{3}{4} )

=  >  \frac{ - 7}{2}   +  \frac{ - 11}{4}

=  >  \frac{ - 25}{4}  =6.25

3) 1 \frac{1}{4}  + 2 \frac{1}{2}

=  >  \frac{5}{4}  +  \frac{5}{2}

=  >  \frac{15}{4}  = 3.75

4) - 9.5 + 6 =  - 3.5

5)

Amount of water collected on a month = 8.4 gallons

Amount of water used in garden = 5.2 gallons

Amount of water used in flowers = 6.5 gallons

Total amount of water used up = 5.2 + 6.5 = 11.7 gallons

Dat gurl saved 8.4 gallons in that month & she used up 11.7 gallons water. So, the rainwater supply was decreased by (11.7 - 8.4) = 3.3 gallons

Answer:

A measure of average is a value that is typical for a set of figures. Finding the average helps you to draw conclusions from data. The main types are mean, median and mode. Data is also often grouped.

Step-by-step explanation:

To find the mean add all the ages together and divide by the total number of children.

If you type all those ages into a calculator it is easy to make an error.

You unfold chicken wire to make a circular pen. The area of the pen is 78.5 square meters. How many meters of chicken wire do yo
Lelu [443]
Circular pen means you are going to use Area = Pi(r^2). 

So 78.5 = pi(r^2). Divide by pi on both sides to get r^2 = 78.5/pi. Take the square root of that to get r or radius = approximately 4.99. If you need an exact answer then use \sqrt{ \frac{78.5}{ \pi } } for the next part because you are not done yet.

Plug whatever R you use into the circumference formula of Circumference = 2(pi)(r).

If you use 4.99, you do 2(pi)(4.99) which is approximately 31.35. If you use the exact answer, you do 2(pi)(\sqrt{ \frac{78.5}{ \pi} }) which gives you approximately 31.41. 

Either way you'll need about 31 meters of chicken wire but the 31.40796 or ~31.41 is closer to the exact answer.

Is the following number negative, positive or neither?<br> -6 1/2
Annette [7]

Answer:

negative.

Step-by-step explanation:

what is half of -6?

=-3, negative.

You owe your friend 6 dollars, and you have 0 dollars.

Your friend told you: you only have to pay half the money

so, instead of owing 6 dollars, you owe 3 dollars, which will still be equal to -3 dollars from your wallet :)
