Answer:

7\frac{1}{2} hours will it take to fill 4 aquarium

Step-by-step explanation:

Unit rate defined as the rates are expressed as a quantity 1, such as 3 feet per second or 6 miles per hour, they are called unit rate

As per the statement: Terrence was filling the new fish aquariums where he works. He was able to fill 1\frac{1}{3}=\frac{4}{3}aquariums in  2\frac{1}{2} = \frac{5}{2} hours.

\text{Unit rate per hour} = \frac{\text{Number of aquariums}}{\text{Number of hours}}

Substitute the given values we get;

\text{Unit rate per hour} = \frac{\frac{4}{3}}{\frac{5}{2}}}

Simplify:

\text{Unit rate per hour} = \frac{8}{15}

Now, to find the number of hours will it take to fill 4 aquarium.

{\frac{8}{15}} = \frac{4}{\text{Number of hours}}

or

\text{Number of hours} = \frac{4}{\frac{8}{15}} = 4 \times \frac{15}{8} = \frac{15}{2} = 7\frac{1}{2}

therefore, it will take to fill aquarium is, 7\frac{1}{2} hours

he U.S. Bureau of Labor Statistics reports that the average annual expenditure on food and drink for all families is $5700. Assu
Papessa [141]

Answer:

87.08% percentage of families spend more than $4000 annually on food and drink

Step-by-step explanation:

Given -

average annual expenditure on food and drink for all families is $5700

Mean  (\nu) = 5700

standard deviation (\sigma ) = 1500

Let X be the no of families spend annually on food and drink

percentage of families spend more than $4000 annually on food and drink =

P(X > 4000)  = P(\frac{X - \nu }{\sigma }> \frac{ 4000 - 5700}{1500})

                      =  P(Z > - 1.13)     Using  (Z = \frac{X - \nu }{\sigma })

                      =  1 - P(Z

                      = 1 - .1292

                      = .8708

                       = 87.08%

If you have 20 coins worth $1.35, and you only have nickels and dimes, how many do you have of each coin?
ankoles [38]
N + d = 20....n = 20 - d
0.05n + 0.10d = 1.35

0.05(20 - d) + 0.10n = 1.35
1 - 0.05d + 0.10d = 1.35
-0.05d + 0.10d = 1.35 - 1
0.05d = 0.35
d = 0.35/0.05
d = 7 <==== 7 dimes

n + d = 20
n + 7 = 20
n = 20 - 7
n = 13 <=== 13 nickels

What is the difference in surface areas, in square feet, of the two boxes?
Katarina [22]
The difference is 3ft since the surface area for the prism is 57, and the surface area for the cube is 54.

You can use the surface area formula
2(wl+hl+hw) = Area
2·(3·4.5+2·4.5+2·3)=57

And a cubes surface area formula
6a^2 = Area
6·32=54
