Answer:

The truck travels 40 miles per hour.

Step-by-step explanation:

You can use proportion to solve this.

[tex] \frac{2400 \: miles}{60 \: hours} = \frac{x}{1 \: hour} \\ \\ \frac{60x}{60} = \frac{2400}{60} \\ \\ x = 40[/tex]

Answer:

The answer should be about $81.20

Step-by-step explanation:

$14.50 x 5weeks = $72.50

A school week is usually 5 days.

The middle of the week is Wednesday, so that's 3 whole days.

$14.50 / 5days = $2.90 per day

$2.90 x 3days = $8.70

$72.50 + $8.70 = $81.20

Answer:here are approximately 143 women

Step-by-step explanation:

Step 1

Given that for every 19 women, there are 81 men in the United States Air Force therefore we can say the ratio between the men and women is given as 81:19

such  that the fraction to represent men = ratio of men/ total ratio of men and women

81/(19 + 81)= 81/ 100 =0.81

and the fraction to represent women = ratio of women/ total ratio of men and women

19/(19 + 81)= 19/ 100 = 0.19

Step 2-

To calculate the number of men in a 750 squadron, we have that

fraction of men x number of members

=0.81 x 750= 607.5 ≈ 608

To calculate the number of women in a 750 squadron, we have that

fracton of women x number of members

=0.19 x 750= 142.5 ≈ 143

Therefore there are approximately 143 women .

The correct equation for this given condition is;

⇒ s = $56 + $4w

Where, 's' is amount of savings and 'w' is number of weeks.

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

Given that;

Francisco is saving money in an account.

The savings amount = $56

And, Put in another $4 per week.

Now,

Let number of weeks = w

And. Total amount in saving amount = s

So, We can formulate;

⇒ s = $56 + $4w

Thus, The correct equation for this given condition is;

⇒ s = $56 + $4w

Where, 's' is amount of savings and 'w' is number of weeks.

Answer:

The answer is 3.6

Step-by-step explanation:

Step one:

Singer A is offering his services for an initial $95 in addition to $12.95 per hour

let the number of hours be x and the total charge be y

the expression for the total for singer A is

y=12.95x+95----------2

Singer B is offering her services for an initial $99 in addition to $11.85 per hour

let the number of hours be x and the total charge be y

the expression for the total for singer A is

y=11.85x+99----------2

Step two:

Equating 1 and 2 we have

12.95x+95=11.85x+99

collect liker terms

12.95x-11.85x=99-95

1.1x=4

divide both sides by 1.1

x= 4/1.1

x=3.63

to the nearest tenth it is 3.6

Answer:

The change is increasing with a percentage of change of 64%

Step-by-step explanation:

Since we have the present grater than the original, then the change is increasing

Secondly, we want to calculate the percent of change

Mathematically , that will be ;

(present - original)/original * 100%

= (90-55)/55 * 100%

= 35/55 * 100% = 63.63 which is approximately 64%

Answer:

[tex]y = \frac{1}{5}x +\frac{13}{5}[/tex]

Step-by-step explanation:

Given

[tex](x_1,y_1) = (2,3)[/tex]

[tex](x_2,y_2) = (7,4)[/tex]

Required

Complete the equation y - 4.....

First, we need to determine the slope as follows:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{4 - 3}{7 - 2}[/tex]

[tex]m = \frac{1}{5}[/tex]

The equation is then calculated as thus:

[tex]y - y_1 = m(x - x_1)[/tex]

This gives:

[tex]y - 4 = \frac{1}{5}(x -7)[/tex]

Open bracket

[tex]y - 4 = \frac{1}{5}x -\frac{7}{5}[/tex]

Add 4 to both sides

[tex]y - 4 +4= \frac{1}{5}x -\frac{7}{5} + 4[/tex]

[tex]y = \frac{1}{5}x -\frac{7}{5} + 4[/tex]

[tex]y = \frac{1}{5}x +\frac{-7+20}{5}[/tex]

[tex]y = \frac{1}{5}x +\frac{13}{5}[/tex]

Answer:

B. Baseball cap

Step-by-step explanation:

Given that:

Total money available with Annabeth = $29.00

Amount at which T-shirt was bought = $15.32

Things that Annabeth wants to buy:

Soccer ball for the price of $12.87 or

Baseball cap for the price of $8.39 or

Set of shin guards for the price of $14.98 or

Water bottle for the price of $5.93

The equation that can be used to find the cost of most expensive item with the remaining amount of money:

$15.32 + [tex]c[/tex] = $29.00

[tex]\Rightarrow c = 29 - 15.32\\\Rightarrow c= \$13.68[/tex]

Cost of items that can be bought in the decreasing order is:

Cost of pair of shin guards ( $14.98 ) > Cost of soccer ball ( $12.87 ) > Cost of baseball cap ($8.39) > Cost of water bottle ( $5.93 )

The most expensive item that can be bought is the Soccer ball at $12.87.

Answer is:

B. Soccer ball

Cost of shin guards is more than the amount of money remaining.

The 10th term of the sequence is:

Step-by-step explanation:

Given the number

729, 243, 81, 27...

A geometric sequence has a constant ratio 'r' and is defined by

[tex]a_n=a_0\cdot r^{n-1}[/tex]

Computing the ratio of all the adjacent terms

[tex]\frac{243}{729}=\frac{1}{3},\:\quad \frac{81}{243}=\frac{1}{3},\:\quad \frac{27}{81}=\frac{1}{3}[/tex]

The ratio of all the adjacent terms is the same and equal to

[tex]r=\frac{1}{3}[/tex]

also

[tex]a_1=729[/tex]

Therefore, the nth term is computed by:

[tex]a_n=729\left(\frac{1}{3}\right)^{n-1}[/tex]

Putting n = 10 to find the 10th term

[tex]a_{10}=729\left(\frac{1}{3}\right)^{10-1}[/tex]

     [tex]=729\cdot \frac{1}{3^9}[/tex]

      [tex]=\frac{1\cdot \:729}{3^9}[/tex]

      [tex]=\frac{729}{3^9}[/tex]

      [tex]=\frac{3^6}{3^9}[/tex]

      [tex]=\frac{1}{3^3}[/tex]

[tex]a_{10}=\frac{1}{27}[/tex]

Therefore, the 10th term of the sequence is:

Answer:

35 grams

Step-by-step explanation:

The ratio of zinc to copper is 3 to 11

A jar of chemical contains 385 grams if copper

Therefore the number of grams of zinc it contains can be calculated as follows

3/11= x/385

11x= 385

x= 385/11

= 35 grams

Hence the chemical contains 35 grams of zinc

Answer:

The volume of the resulting cylinder is 385 cm³

Step-by-step explanation:

The formula of the rule of a cylinder is V = π r² h, where

When a rectangular paper folded to form a cylinder, then one of its dimension will be the circumference of the base and the other dimension will be the height of the resulted cylinder

∵ ABCD is a rectangle

∵ It is folded where AB coincides with DC

∴ AB is the height of the resulted cylinder

∴ BC is the circumference of the base of the resulted cylinder

∵ AB = 10 cm

∴ h = 10 cm

∵ BC = 22 cm

∴ The circumfrence  of the base = 22 cm

∵ The circumference of a circle = 2 π r

→ Equate the rule by 22 to find r

∴ 2 π r = 22

∵ π = [tex]\frac{22}{7}[/tex]

∴ 2 × [tex]\frac{22}{7}[/tex] × r = 22

∴ [tex]\frac{44}{7}[/tex] r = 22

→ Divide both sides by [tex]\frac{44}{7}[/tex]

∴ r = 3.5 cm

→ Use the formula of the volume above to find the volume of the cylinder

∵ V = [tex]\frac{22}{7}[/tex] × (3.5)² × (10)

∴ V = 385 cm³

∴ The volume of the resulted cylinder is 385 cm³
