\frac{40(7)}{5}Answer:

To find out how many can be filled, divide the number of pounds of candy by the number of pounds a single bag can hold.

40 can be considered 40/1.

So,

40/1 ÷ 5/7

Make 5/7 a reciprocal(basically flipping the fraction upside down):

40/1 ÷ 7/5

Convert the division symbol into a multiplication symbol:

40/1 × 7/5

Solve!

\frac{40(7)}{5}

Cancel:

\frac{8(7)}{1}

= <u>56 bags</u> can be filled.

Answer:56 bags

Step-by-step explanation:

you are dividing 40 into 5/7 so its technically 40*7 divided by 5, which equals 56. double check by doing 56*5 divided by 7 and you get 40 pounds,

Elina [12.6K]

Answer:

distance = 1.5 miles(approx.)

Step-by-step explanation:

given,

speed of sound = 1130 ft/s        

1 ft = 0.3048            

1130 ft/s = 0.3048 × 1130 m/s      

              = 344.424 m/s          

time = 7 second                

distance = speed × time                

distance = 344.424 × 7              

distance = 2410.968 m                    

1 m = 0.0006214 miles                    

2410.968 m =  (0.0006214 ×  2410.968) miles    

distance = 1.498 miles                        

distance = 1.5 miles(approx.)

A paper company needs to ship paper to a large printing business. The paper will be shipped in small boxes and large boxes. The
Delvig [45]

10 small boxes and 11 large boxes were shipped.

Step-by-step explanation:

Given,

Total boxes shipped = 21

Total volume of shipped boxes = 342 cubic feet

Volume of each small box = 10 cubic feet

Volume of each large box = 22 cubic feet

Let,

Number of small boxes = x

Number of large boxes = y

According to given statement;

x+y=21     Eqn 1

10x+22y=342    Eqn 2

Multiplying Eqn 1 by 10

10(x+y=21)\\10x+10y=210\ \ \ Eqn\ 3

Subtracting Eqn 3 from Eqn 2

(10x+22y)-(10x+10y)=342-210\\10x+22y-10x-10y=132\\12y=132

Dividing both sides by 12

\frac{12y}{12}=\frac{132}{12}\\y=11

Putting y=11 in Eqn 1

x+11=21\\x=21-11\\x=10

10 small boxes and 11 large boxes were shipped.

SAT verbal scores are normally distributed with a mean of 433 and a standard deviation of 90. Use the Empirical Rule to determin
laila [671]

34% of the scores lie between 433 and 523.

Solution:

Given data:

Mean (μ) = 433

Standard deviation (σ) = 90

<u>Empirical rule to determine the percent:</u>

(1) About 68% of all the values lie within 1 standard deviation of the mean.

(2) About 95% of all the values lie within 2 standard deviations of the mean.

(3) About 99.7% of all the values lie within 3 standard deviations of the mean.

$Z(X)=\frac{x-\mu}{\sigma}

$Z(433)=\frac{433-\ 433}{90}=0

$Z(523)=\frac{523-\ 433}{90}=1

Z lies between o and 1.

P(433 < x < 523) = P(0 < Z < 1)

μ = 433 and μ + σ = 433 + 90 = 523

Using empirical rule, about 68% of all the values lie within 1 standard deviation of the mean.

i. e. ((\mu-\sigma) \ \text{to} \ (\mu+\sigma))=68\%

Here μ to μ + σ = \frac{68\%}{2} =34\%

Hence 34% of the scores lie between 433 and 523.

Terrance made a list of his expenses. He is creating a check-off matrix to organize when his bills are due. A check-off matrix i
valkas [14]

Complete the chart  by marking each of the expenses in the correct cell depending on whether the expense occurs montlhy, quarterly, annually, etc. as shown in the chart.

<h3>What is a check-off matrix?</h3>

This is a type of chart that is completed by adding X to the cells. In the case of expenses, check-off matrixes help you to visualize how often every expense occurs, and therefore it can be useful to control or monitor expenses.

This type of matrix often includes:

-Columns with the months of the year or the initals of these. June = J.

-Rows that show the expenses a person has.

<h3>How to do a check-off matrix?</h3>
  1. List the expenses
  2. Make an X in each of the cells that the each expense should occur.
  3. Verify the information once the chart is finished.

Below you can find the complete chart:
