Suppose x has a distribution with = 64 and = 8.

Thus the largest length is 15 inches

Size (l) is 14 inches.

Size (w) = 4 inches.

Height is 4 inches (h).

The distance between one bottom corner and the opposite top corner is known as d. Find s, the diagonal across the bottom of the box, first.

[tex]w^2 + l^2 = s^2[/tex]

Replace the prescribed measures.

[tex]4^2 + 14^2 = s^2[/tex]

Simplify.

[tex]16 + 196 = s^2[/tex]

[tex]21^2= s^2[/tex]

To determine d, use the expression for s.

[tex]h^2 + s^2 = d^2[/tex]

Plug in s2 = 212 and h = 4.

4^2 + 21^2 = d^2

Simplify.

16 + 21^2 = d^2

228 = d2

On both sides, take the square root.

√228 = √d2

15.1 ≈ d

Therefore, the part's maximum possible length was 15 inches.

The two equations that can be formed by adding or subtracting is

4x−4y = 16 and  2x − 6y = -8 .

the two equations are : x + y = 12 and 3x − 5y = 4

Adding we get :

x + y = 12

3x − 5y = 4

4x -4y = 16

Subtracting we get:

x + y = 12

3x − 5y = 4

-2x + 6y = 8 or 2x - 6y = -8

The probability that the spinner lands on yellow and the coin toss is tails is 9/10.

What is probability?

Probability shows the likelihood of an event happening.  it can be calculated by dividing the number of outcomes of an event by the total number of possible outcomes or sample space. Probability is equal to '1' when the event is certain to occur. i.e P =1. It is less than '1' when it is not likely to occur. i.e P< 1

Probability P=no. outcomes/total no. of the possible outcomes

From the question;

No of blue=1

No of yellow=9

No. of total possible outcome=10

Therefore the probability that the spinner lands on yellow and the coin toss is tails P= 9/10.

Using a linear equation to solve this problem, the charge for a 3.5 hour job is 85.45 dollar.

To find how much was the bill, we need to write an equation or linear equation for this.

For every linear equation, it takes the form of y = mx + c.

Where m and c are the slope and intercepts of the straight line.

In this case, our linear equation can be written as

y = 18.70x + 20

where x = number of hours worked.

If the job took three and a half hour which is 3.5 hours, we can substitute this into the equation and solve.

y = 18.70(3.5) + 20

y = 85.45

In the question ,

it is given that

in 3/4 hours the the level of chocolate syrup was 9 inch ,

So , the first point is (3/4,9) .

in 5/4 hours the level of chocolate syrup in the dispenser was 7 inch .

So , the second point is (5/4,7)

to find the linear equation we first need to find the slope .

How to find whether line is perpendicular or not?

Perpendicular lines are those that cross at a right angle when two non-vertical lines in the same plane. Vertical and horizontal lines, or the axes of the coordinate plane, are perpendicular to one another. Two parallel lines' slopes have negative reciprocal slopes.

The given line is

y=x-1

the slope of it is 1

As the slopes of perpendicular lines are negative reciprocals

So, the slope of the perpendicular line is -1

As the point is(-6,2)

The smaller tap take 25 hours to fill the tank and the larger tap take 10 hours to fill the tank.

How to calculate time taken to fill the tank for each tap?

Given,

Time taken for two tap together to fill the tank = [tex]9\frac{3}{8}[/tex] hours = [tex]\frac{75}{8}[/tex] hours

Time taken for smaller tap to fill the tank = x hours

Time taken for larger tap to fill the tank = x - 10 hours

So,

Tank filled by two tap together in 1 hour = [tex]\frac{8}{75}[/tex]

Tank filled by smaller tap in 1 hour = [tex]\frac{1}{x}[/tex]

Tank filled by larger tap in 1 hour = [tex]\frac{1}{x-10}[/tex]

Then, tank filled by two tap together is equal to tank filled by smaller tap and larger tap. So,

[tex]\frac{8}{75} = \frac{1}{x} + \frac{1}{x-10}[/tex]

[tex]\frac{8}{75} = \frac{x-10+x}{x(x-10)}[/tex]

[tex]\frac{8}{75} = \frac{2x-10}{x^{2}-10x}[/tex]

[tex]8x^{2}-80x = 150x - 750[/tex]

= [tex]8x^{2} - 230x + 750[/tex]

= [tex]2(4x^2 - 115x + 375)[/tex]

= [tex]4x^2 - 100x - 15x + 375[/tex]

= [tex](4x - 15) (x - 25)[/tex]

If, x = [tex]\frac{15}{4}[/tex] then x - 10 for larger tap equal to [tex]\frac{15}{4}[/tex] - 10 = [tex]- \frac{25}{4}[/tex] < 0 hours, so it is impossible.

Then, x must be 25. So, for larger thank is 25 - 10 = 15.

Smaller tap take 25 hours to fill the tank

Larger tap take 15 hours to fill the tank.

Thus, the smaller tap take 25 hours to fill the tank and the larger tap take 10 hours to fill the tank.

Write the value of x when y is = 7

x = 7

x = -1

x = -4

=====================================================

Work Shown:

x = number of nickels

y = number of dimes

5x = value of the nickels only (cents)

10y = value of the dimes only (cents)

5x+10y = total value of all the coins = 75 cents

One equation we can form is 5x+10y = 75.

"he has twice as many dimes as nickels" tells us that y = 2x. We can replace every copy of y with 2x and solve for x as shown in the steps below.

5x+10y = 75

5x+10(y) = 75

5x+10(2x) = 75 ... plug in y = 2x

5x+20x = 75

25x = 75

x = 75/25

x = 3

This value leads to y = 2x = 2*3 = 6

Johnny has 3 nickels and 6 dimes.

------------------

Check:

1 nickel = 5 cents

3 nickels = 3*5 = 15 cents

1 dime = 10 cents

6 dimes = 6*10 = 60 cents

3 nickels + 6 dimes = 15 cents + 60 cents = 75 cents = $0.75
