Answer:

There are 15 girls

Step-by-step explanation:

Given:- Ratio of boys to girls = 5:3

And, the number of boys = 75

let the girls be 5x and boys be 3x

so, 5 × 75 { given }

x = 75/5 = 15

6x= 6 × 15 = 90

6x/6 = 90/6 = 15

The number of the possible combinations from rolling a sixteen-sided and a twenty-sided dice at the same time is 320.

The arrangement of the different things or numbers in a number of ways is called the combination.

The possible outcomes for dice with 16 sides:-

{ 1,2,3,4,5,6,...............16}

The possible outcomes for dice with 20 sides:-

{ 1,2,3,4,5,6,...............20}

So the number of the possible pairs will be:-

=   16   x    20

=   320  pairs.

Therefore the number of the possible combinations from rolling a sixteen-sided and a twenty-sided dice at the same time is 320.

Step-by-step explanation:

The new length, width, and the height of the cuboid are (L+2) inches, (W+2) inches, and (H+2) inches respectively

It is defined as the six-faced shape, a type of hexahedron in geometry. As the old length, width, and height are not given so we are assuming the length of the box is L, width is W, and height is H.

Dave wants to add 2 inches to the minimum length, width, and height of the box. Including the additional space. So the new length = (L+2) inches

New width = (W+2) inches

New height = (H+2) inches

Thus, the new length, width, and height are (L+2) inches, (W+2) inches, and (H+2) inches respectively.

Answer:

General form of a linear equation:  [tex]y=mx+b[/tex]

(where m is the slope and b is the y-intercept)

A linear equation has a constant rate of change which is represented by the slope (m).  It is the rate at which one quantity is changing with respect to another quantity.

Part (a)

Given equation:  [tex]y=-9x+55000[/tex]

where:

The rate of change (slope) is -9 and represents that for every 1 mile driven, the value of the car decreases by $9.

The initial value is the y-intercept (b) as this is the value when x = 0.

Therefore, the initial value of car is $55,000.

Part (b)

To find the number of miles at which the car be valued at $35,002, set the equation to $35,002 and solve for x:

[tex]\implies -9x+55000=35002[/tex]

[tex]\implies -9x=35002-55000[/tex]

[tex]\implies -9x=-19998[/tex]

[tex]\implies x=\dfrac{-19998}{-9}[/tex]

[tex]\implies x=2222[/tex]

Therefore, the car will be valued at $35,002 after 2,222 miles.

Given equation:  [tex]y=0.39x+2.55[/tex]

where:

The rate of change (slope) is 0.39 and represents that for every increase of 1 oz of weight in carrots, the price of the carrots increases by $0.39

The initial value is the y-intercept (b) as this is the value when x = 0.

Therefore, the initial cost of the carrots is $2.55.

Part (b)

To find the weight of carrots you can buy for $6.06, set the equation to $6.06 and solve for x:

[tex]\implies 0.39x+2.55=6.06[/tex]

[tex]\implies 0.39x=6.06-2.55[/tex]

[tex]\implies 0.39x=3.51[/tex]

[tex]\implies x=\dfrac{3.51}{0.39}[/tex]

[tex]\implies x=9[/tex]

Therefore, you can buy 9 oz of carrots for $6.06

Part (c)

To find out how much it costs to buy 21 oz of carrots, substitute x = 21 into the equation and solve for y:

[tex]\implies y=0.39(21)+2.55[/tex]

[tex]\implies y=10.74[/tex]

Therefore, it costs $10.74 to buy 21 oz of carrots.

The division equation that has a quotient of 13 is 1/1/13 = 13

The given parameters are:

A division equation is represented as:

Dividend/Divisor = Quotient

Substitute 13 for the Quotient

Dividend/Divisor = 13

Recall that:

Unit fraction = 1/n

So, we have:

Dividend/1/n = 13

Let n = 13.

So, we have:

Dividend/1/13 = 13

This gives

13 * Dividend = 13

Divide both sides by 13

Dividend = 1

So, we have:

1/1/13 = 13

The time Akeem runs on days must be 9.3 minutes or less than 9.3 minutes if the mean running time for 7 days must be 9 minutes or less.

It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.

We have:

Akeem will record the time it takes him to run 1 mile each day for 7 days. In order to meet his fitness challenge, his mean running time for 7 days must be 9 minutes or less.

Here we are assuming that it is required to find the time Akeem runs on the 7th day.

Let's suppose Akeem runs x minutes on the 7th day.

Mean running time ≤ 9

The mean:

[tex]\dfrac{(9.4+9.0+9.1+8.9+8.5+8.8+x)}{7} \leq 9[/tex]

[tex]\dfrac{(53.7+x)}{7} \leq 9[/tex]

53.7 + x ≤ 63
