Jon makes $15 per hour and works 20 hours per week, giving him weekly earnings of $300. Over a year (52 weeks), this totals to $15,600.

The question is asking about how much Jon will earn in a year. We know that Jon makes $15 per hour and works 20 hours per week. To find out his weekly earnings, we multiply his hourly rate by the number of hours he works per week: $15 * 20 = $300.

There are generally 52 weeks in a year. So, to calculate Jon's annual earnings, we can multiply his weekly earnings by 52: $300 * 52 = $15,600.

So, Jon will earn $15,600 in a year if he continues to work at this same rate.

Divide both sides by 3

x>4

Step-by-step explanation: When you are asked to solve an inequality like the one in this problem, your goal is the same as it is when solving equations which is to get x by itself on one side.

In this problem, since x is being multiplied by 3 on the left side of the inequality, to get x by itself, we divide both sides by 3.

Answer: Angle Q= 123

Step-by-step explanation:

4x+1+9x-3=180

X=14

9(14)-3=123

The measurement of angle Q is 123 degrees if angle P and angle Q are supplementary angles.

When two lines or rays converge at the same point, the measurement between them is called a "Angle."

It is given that:

Angle P and angle Q are supplementary angles. if angle P measures 4x + 1 and angle Q measures 9x -3,

As we know the sum of the supplementary angles is up to 180 degrees

Angle P + Angle Q = 180

4x + 1 + 9x  - 3 = 180

13x - 2 = 180

13x = 180 + 2

13x = 182

x = 182/13

x = 14

The measurement of the angle Q = 9x - 3

The measurement of the angle Q = 9(14) - 3

The measurement of the angle Q = 126 - 3

The measurement of the angle Q = 123 degrees

Thus, the measurement of angle Q is 123 degrees if the angle P and angle Q are supplementary angles.

Answer:

The 3% milk quantity to be mixed is 15 liters and the the 15% cream quantity to be mixed is 5 liters

Step-by-step explanation:

The question is

Milk and cream contain different percents of butterfat. How much 3% milk needs to be mixed with how much 15% cream go give 20 L of 6% cream?

Let

x -----> the 3% milk quantity to be mixed

y -----> the 15% cream quantity to be mixed

we know that

[tex]3\%=3/100=0.03[/tex]

[tex]15\%=15/100=0.15[/tex]

[tex]6\%=6/100=0.06[/tex]

[tex]x+y=20[/tex]

[tex]x=20-y[/tex] -----> equation A

[tex]0.03x+0.15y=0.06(20)[/tex]

Multiply by 100 both sides

[tex]3x+15y=120[/tex] -----> equation B

substitute equation A in equation B and solve for y

[tex]3(20-y)+15y=120[/tex]

[tex]60-3y+15y=120[/tex]

[tex]12y=120-60[/tex]

[tex]y=60/12[/tex]

[tex]y=5\ l[/tex]

Find the value of x (equation A)

[tex]x=20-5=15\ l[/tex]

therefore

The 3% milk quantity to be mixed is 15 liters and the the 15% cream quantity to be mixed is 5 liters

Let 2_1/2 = 5/2.

Let t = time to fill 8 tires

(5/2)/8 = (5/2)/t

8(5/2) = (5/2)t

20 = (5/2)t

20 ÷ 5/2 = t

20 • 2/5 = t

8 seconds = t

Done.

Using the ratio of 1 tire per second, it would take an air compressor 8 seconds to fill 8 tires.

This problem requires you to use a simple ratio or proportion to find the answer. First, we begin with the known fact that it takes 2 1/2 seconds to fill 2 1/2 tires. Therefore, it takes 1 second to fill 1 tire because 2 1/2 divided by 2 1/2 equals 1.

Next, if it takes 1 second to fill 1 tire, then approximately it will take 1 times 8 or 8 seconds to fill 8 tires. So, if we use the same air compressor and assuming the tires are the same, it will take 8 seconds to fill 8 tires.

When simplified, this is -1/4

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (1, 2) and (x₂, y₂ ) = (6, 5)

m = [tex]\frac{5-2}{6-1}[/tex] = [tex]\frac{3}{5}[/tex], thus

y = [tex]\frac{3}{5}[/tex] x + c ← is the partial equation of the line

To find c substitute either of the 2 points into the partial equation

Using (1, 2), then

2 = [tex]\frac{3}{5}[/tex] + c ⇒ c = 2 - [tex]\frac{3}{5}[/tex] = [tex]\frac{7}{5}[/tex]

y = [tex]\frac{3}{5}[/tex] x + [tex]\frac{7}{5}[/tex] ← in slope- intercept form

Answer:

The amount invested at 4% was $600

The amount invested at 7.5%  was $3,600

Step-by-step explanation:

Let

x ----> the amount invested at 4%

$4,200-x -----> amount invested at 7.5%

we know that

The total interest earned is equal to the interest earned by the amount invested at 4% plus the interest earned by the amount invested at 7.5%

Remember that

[tex]4\%=4/100=0.04[/tex]

[tex]7.5\%=7.5/100=0.075[/tex]

[tex]7\%=7/100=0.07[/tex]

so

The linear equation that represent this situation is

[tex]0.04x+0.075(4,200-x)=0.07(4,200)[/tex]

Solve for x

[tex]0.04x+315-0.075x=294[/tex]

[tex]0.075x-0.04x=315-294[/tex]

[tex]0.035x=21[/tex]

[tex]x=\$600[/tex]

[tex]\$4,200-x=\$3,600[/tex]

therefore

The amount invested at 4% was $600

The amount invested at 7.5%  was $3,600

Final answer:

Morgan invested $600 in the account with 4% interest and $3,600 in the account with 7.5% interest by setting up a system of equations and solving for both variables.

Explanation:

Calculating Investment Distribution

To find out how much money Morgan put in each account, we need to set up a system of equations. Let's designate x as the amount put into the account with 4% interest, and y as the amount put into the account with 7.5% interest. We know the total investment is $4,200, so our first equation is x + y = 4200.

Morgan earned 7% interest on the total investment. The interest from each account can be represented as 0.04x for the 4% account and 0.075y for the 7.5% account. The total interest earned is 7% of $4,200, which is $294. This gives us the second equation: 0.04x + 0.075y = 294.

To solve the system, we can use the substitution or elimination method. If we solve the first equation for y, we get y = 4200 - x. Substitute this into the second equation to get: 0.04x + 0.075(4200 - x) = 294. Now solve for x:

So Morgan invested $600 in the 4% account. Now we can find y:

Therefore, Morgan invested $3,600 in the 7.5% account.

x = 2 ± [tex]\sqrt{13}[/tex]

Step-by-step explanation:

To find the zeros let y = 0, that is

x² - 4x - 9 = 0 ( add 9 to both sides )

x² - 4x = 9

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 2) x + 4 = 9 + 4

(x - 2)² = 13 ← take the square root of both sides

x - 2 = ± [tex]\sqrt{13}[/tex] ← add 2 to both sides

x = 2 ± [tex]\sqrt{13}[/tex]

2. [tex]\(\sqrt{0.0256} = 0.16\)[/tex] (taking the square root of 0.0256)

Now, substitute these values back into the original expression:

[tex]\[0.99 - 0.16\][/tex]

Finally, subtract 0.16 from 0.99:

[tex]\[0.99 - 0.16 = 0.83\][/tex]

Final answer:

The integer representing the change in the number of gallons of water in the tank after 7 days is -35, as the tank loses 5 gallons per day.

Explanation:

If a water tank leaks 5 gallons of water each day, the total amount of water it would lose in seven days is calculated by multiplying the daily water loss by the number of days. The calculation steps are:

Determine the daily water leakage: 5 gallons per day.

Multiply the daily leakage by the number of days: 5 gallons/day × 7 days.

Calculate the total leakage over seven days: 35 gallons.

As water is being lost from the tank, the change in the number of gallons in the tank after 7 days would be represented by a negative integer, since it is a decrease in the volume of water. Therefore, the integer representing the change in the water level is -35.
