Answer:  1953125

Step-by-step explanation:

Answer:

1 out of 3 or 1/3.

Step-by-step explanation:

to get the equation of any straight line, we simply need two points off of it, let's notice the picture above, the line passes through the origin and (8 , -5), so let's use those two points then

[tex]\stackrel{origin}{(\stackrel{x_1}{0}~,~\stackrel{y_1}{0})}\qquad (\stackrel{x_2}{8}~,~\stackrel{y_2}{-5}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-5}-\stackrel{y1}{0}}}{\underset{run} {\underset{x_2}{8}-\underset{x_1}{0}}} \implies \cfrac{ -5 }{ 8 } \implies - \cfrac{5 }{ 8 }[/tex]

[tex]\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{0}=\stackrel{m}{- \cfrac{5 }{ 8 }}(x-\stackrel{x_1}{0})\implies {\Large \begin{array}{llll} y=-\cfrac{5}{8}x \end{array}}[/tex]

Answer:

The answer is [tex]\frac{13}{30}[/tex].

Step-by-step explanation:

Solve by completing fraction division.

Thus, solve [tex]\frac{5}{6} - \frac{2}{5}[/tex], since [tex]\frac{5}{6}[/tex] is larger than [tex]\frac{2}{5}[/tex].

[tex]\frac{5}{6} - \frac{2}{5}[/tex]

[tex]= \frac{25}{30} - \frac{12}{30}[/tex]

[tex]= \frac{13}{30}[/tex]

Hence, the answer is [tex]\frac{13}{30}[/tex].

The cost for the store to purchase the electric toothbrush will be;

⇒ $22.40

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Given that;

The cost of electric toothbrush = $56

And, The price of markup = 40%

Now,

Since, The cost of electric toothbrush = $56

And, The price of markup = 40%

So, The cost for the store to purchase the electric toothbrush is;

=  (40% of $56)

= (40/100 x 56)

=  $22.4

Thus, The cost for the store to purchase the electric toothbrush will be;

⇒ $22.40

Answer:

Using proportions, it is found that $1,225 is earned from nachos.

This question is solved by proportions, using a rule of three.

The measures have an inverse relationship, hence line multiplication is applied instead of cross multiplication.

When the theater makes $1,540 from popcorn sales, it makes $1,330 from nacho sales. How much is earned from nachos when $1,672 is earned from popcorn?

The rule of three is:

$1,540 - $1,330

$1,672 - $x

Applying line multiplication:

$1,225 is earned from nachos.

Answer: 12 gold, 2 silver and 2 bronze

Step-by-step explanation:

16 is the total number of medals and in the ration 6:1:1 there are 8. To get to 16 total medals you need to double each of them. 6x2, 1x2 and 1x2. Now you have a ratio of 8:2:2. 8+2+2=16.

The number of medals of gold, silver, and bronze will be 12, 2, and 2, respectively.

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

Your group wins 16 decorations at a rivalry. The decorations are gold (G), silver (S), and bronze (B) in a proportion of 6: 1: 1.

G/6 = S/1 = B/1 = x

G = 6x

S = x

B = x

Then the equation is written as,

6x + x + x = 16

8x = 16

x = 16 / 8

x = 2

Then the number of each medal is given as,

G = 6x = 6(2) = 12

S = x = 2

B = x = 2

The number of medals of gold, silver, and bronze will be 12, 2, and 2, respectively.

Answer: Option 4

Step-by-step explanation:

Commutative property is when you change the order of the operands but it does not change the answer like 5 times 6 and 6 times 5 all = 30.

In this case, the fourth answer is correct because 7/15 x -11 x 30 is the same as 7/15 x 30 x -11 but -11 and 30 are switched around.

Answer:

Filling the chart to estimate the amount of each type of food that each family will receive is as follows:

Rounded Food Items and Families:

Food Item Number of Pounds Number of Families Estimated

Rounded Receiving Item Receiving

Chicken rolls 113 10 11.3

Mashed potatoes 7 12 0.6

Corn 28 10 2.8

Green bean 19 11 1.7

Casserole 5 3 1.7

What is an estimate?

An estimate is a rough calculation based on available information or rounded-off data.

Estimates are made to enable quick decisions without knowing complete details.

For this estimate, we used the division operation to obtain the quotients that should be the share of receiving families from each food category.

Original Data:

Food Item Number of Pounds Number of Families

Available Receiving Item

Chicken rolls 113.4 9

Mashed potatoes 6.6 12

Corn 28.5 10

Green bean 18.92 11

Casserole 5.37 3

Thus, as much as possible, some pounds of food items have been rounded to enable the estimate to be produced.

The Complete Table for Rounded Food Items and Families is shown below

An estimate is a rough computation made using information that is currently known or data that has been rounded off.

Estimates are created to help in decision-making quickly without having all the information.

So, In order to determine the quotients that represent the share of receiving households from each food group for this estimate, we employed the division procedure.

Original Data:

Food Item             Number of Pounds     Number of Families

                                    Available                   Receiving Item

Chicken rolls                    113.4                              9
