Solve the proportions. Can you please solve this one problem for me it may not be too hard for you.

Volume of small box :

[tex]v=l\times b\times h\\\\v=2\times 3\times 4\\\\v=24\ units^3[/tex]

Volume of big box :

[tex]V=L\times B\times H\\\\V=12\times 21\times 40\\\\V=10080\ units^3[/tex]

Number of small boxes that can fit into bigger box :

[tex]n=\dfrac{V}{v}\\\\n=\dfrac{10080}{24}\\\\n=420[/tex]

Therefore , 420 such boxes can fit .

Hence , this is the required solution .

Answer:

1085/3 = 361.7

Step-by-step explanation:

 Expand  −8.68/0.024 ≈361.666666667 by multiplying both numerator and the denominator by 1000.

8680/-24 ≈361.666666667

Reduce the fraction  −8680/24≈361.666666667 to lowest terms by extracting and canceling out −8.

1085/3≈361.7

Answer:

Verbal expression; The sum of thirty -two and a number w

Algebraic expression ;32+w

Step-by-step explanation:

Answer:

Michael's present age = p + 5

Michael's present age = 3p + 15

Sum of there ages 6 year age = 5p + 38

Sum of there ages 3 year ago = 5p - 11

Step-by-step explanation:

Assume;

Age of Rui Feng = x

Age of Micheal = x + 5

Age if Vishal = 3[x+5]

Given:

Age of Rui Feng = P

Computation:

Michael's present age = Age of Rui Feng + 5

Michael's present age = p + 5

Vishal's present age = 3[p + 5]

Michael's present age = 3p + 15

Sum of there ages 6 year age = [p + 6] + [p + 5 + 6] + 3[p + 5] + 6

Sum of there ages 6 year age = 5p + 38

Sum of there ages 3 year ago = [p - 3] + [p + 5 - 3] + 3[p + 5] - 3

Sum of there ages 3 year ago = 5p - 11

Given :

Temperature at first period , [tex]T_1=99^oF[/tex] .

Temperature at seventh period , [tex]T_7=102^oF[/tex] .

To Find :

The change in temperature .

Solution :

We know , change in temperature is given by the difference between final and initial temperature .

[tex]\Delta T=T_7-T_1\\\\\Delta=(102-99)^oF\\\\\Delta=3^oF[/tex]

So ,the change in temperature is [tex]3^oF[/tex] .

Now , the average body temperature of human body is [tex]98.6^oF[/tex] and [tex]100.4^oF[/tex] is considered a fever .

Therefore , we should not be in school and take rest .

Hence , this is the required solution .

Answer:

[tex]x = \frac{2}{3} [/tex]

Step-by-step explanation:

[tex]x - 5(x - 1) = x - (2x - 3) \\ x - 5x + 5 = x - 2x + 3 \\ x - 5x + 2x - x= 3 - 5 \\ - 3x = - 2[/tex]

Divide both sides of the equation by -3

[tex] \frac{ - 3x}{ - 3} = \frac{ - 2}{ - 3} \\ x = \frac{2}{3} [/tex]

Answer:

x = 7

Step-by-step explanation:

160+3x=195-2x

Add 2x to each side

160+3x+2x=195-2x+2x

160 +5x = 195

Subtract 160 from each side

160+5x-160 = 195-160

5x = 35

Divide by 5

5x/5 = 35/5

x = 7

Answer:

Table 1

Step-by-step explanation:

Constant of proportionality is simply the ratio of y to x. In each of the given tables, the second column is y and the first is x.

Table 1:

4       32/5

10      16

11       88/5

Let's find the constant of proportionality for each row:

R1: (32/5) / 4 = 8/5

R2: 16/10 = 8/5

R3: (88/5) / 11 = 8/5

Thus, since this matches the requirements and all three rows have the same constant, Table 1 is the answer.

If you check the other two tables in the same way, you'll see that neither has a constant of proportionality of 8/5.

Hope this helps!

Answer:

1/16

Step-by-step explanation:

Probability helps us to know the chances of an event occurring. The probability that all four pennies will be tails is (1/16).

Probability helps us to know the chances of an event occurring.

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

The probability of a penny getting a tail is 0.5 or (1/2), therefore, the probability of four penny getting a tail can be written as,

[tex]\rm Probability = \dfrac14 \times \dfrac14 \times \dfrac14 \times \dfrac14 = \dfrac1{16}[/tex]

Hence, the probability that all four pennies will be tails is (1/16).

The length of the blue ribbon is approximately 8.333 inches

Step-by-step explanation:

The given information are as follows;

The given length of the red ribbon = 2 1/12 inches

The length of the blue ribbon is given as 4 × The length of the red ribbon

Therefore;

The length of the blue ribbon = 4 × 2 1/12 inches = 25/3 inches = 8 1/3 inches

The length of the blue ribbon = 8 1/3 inches ≈ 8.333 inches.

n = -13

Step-by-step explanation:

19 + 10n = 7n - 20

Subtract 7n from each side

19 + 10n-7n = 7n-7n - 20

19+3n = -20

Subtract 19 from each side

19+3n -19 = -20-19

3n = -39

Divide each side by 3

3n/3 = -39/3

n = -13

Answer:

$3.039

Step-by-step explanation:

Step 1

They bought 2 pounds of paper hearts at $ 3.42 per pound

1 pound = $3.42

2 pounds =

2 × $3.42

= $6.84

2 pounds of sparkling stars for $ 3.93 per pound

1 pound of sparking stars = $3.93

2 pounds =

$3.93 × 2

= $7.86

5 pounds of shiny coils for $ 2.53 per pound.

1 pounds of shiny coils = $2.53

5 pounds =

5 × $2.53

= $12.65

Step 2

We find the total cost of the materials

Total cost of Materials that make up the confetti = Cost of paper heart + Cost of sparkling stars + Cost of shiny coils.

= $6.84 + $7.86 + $12.65

= $27.35

Step 3

Total pounds of materials bought = 2 pounds + 2 pounds + 5 pounds

= 9 pounds

Step 4

The cost per pound of confetti = Total cost of the materials bought/ Total pounds of materials

= $27.35/9

= $3.0388888889

Approximately ≈ $3.039

The cost per pound of the confetti = $3.039

The cost per pound of the confetti is  $3.04

Given that, they bought 2 pounds of paper hearts at $ 3.42 per pound.

The cost of 2 pounds of paper hearts is, [tex]=2 *3.42=6.84[/tex]

the 2 pounds of sparkling stars for $ 3.93 per pound

The cost of 2 pounds of sparkling stars is, [tex]=$3.93 * 2=7.86[/tex]

the 5 pounds of shiny coils for $ 2.53 per pound.

The cost of 5 pounds of  shiny coils is, [tex]=5 * $2.53=12.65[/tex]

Total cost of confetti is,

                         [tex]= $6.84 + $7.86 + $12.65=27.35[/tex]

Total pounds of materials bought ,

                          [tex]=2+2+5=9pounds[/tex]

The cost per pound of confetti is,

                         [tex]=\frac{27.35}{9}=3.04[/tex]

The cost per pound of the confetti  is $3.039
