during the summer you work 30 hours per week at a gas station and earned $8.75 per hour. You also work as a landscaper for $11 per hour and your work as many hours as you want. You want to earn a total of $400 per week. How many hours mostly work as a landscaper?

Answers

a very minimum of 12.5 because 30x8.75= 262.5 and when you subtract that from 400 you get 137.5 and that divided by 11 equals 12.5 
Final answer:

To earn a total of $400 per week, considering you already earn $262.50 working 30 hours a week at a gas station, you need to make up the rest ($137.50) working as a landscaper. This equates to approximately 12.5 hours of work a week at an hourly rate of $11.

Explanation:

The nature of the question is mathematical, specifically relating to linear equations. Initially, we know you're earning $8.75 per hour from your job at the gas station, working 30 hours a week, which gives you a total of $8.75 * 30 = $262.50 per week. Your goal is to earn $400 in total per week. Therefore, your earnings from the landscaping job need to make up the difference, which is $400 - $262.50 = $137.50.

Next, to find out how many hours you need to work as a landscaper, we divide that by the landscaper's hourly wage of $11, so $137.50 / $11 = 12.5 hours approximately. Hence to meet your target of $400 per week, you need to work about 12.5 hours as a landscaper, in addition to your 30 hours at the gas station each week.

In the seventh grade, the ratio of girls to boys is 7:5. If there are 21 girls in the seventh grade, how many boys are there?

Answers

There is 15 boys in the Seventh Grade

So we are given the fraction ratio...

7 girls

---------

5 boys

if we make the fraction

21 girls

----------

x boys

equal each other, we can cross multiply and find x.

Cross multiplying means to multiply 7 times x and 21 by 5.

then we set up a little equation

7x = (21)(5) First lets solve what 21 times 5 is 

7x = 105 Now we have to divide both sides by 7 to get x alone.

÷7 = ÷7  On the left side of the equation the 7 cancels and we solve on the right.

x = 15


So we know that when we have 21 girls in the 7th grade classroom we also have 15 boys.

Solve the equation for 15 points PLEASE HELP!!!!!!!

Answers

Relax! This isn't so hard once you grasp it. In an equation like this, what's the first step? Distributive property, right? Multiply 1/3 by 12, then by -24 v, and apply the same process to the other side. This leaves you with 4-8v=-8v+4. Now you need to isolate that variable. You have the same variable on both sides, so you do inverse of subtraction on either one. I'm going to choose the one on the right. You add 8v to both sides, leaving you with 4-v=4. Subtract 4 from the first side, and get -v=4. You aren't solving for -v, so flip the sign, and your final answer is v=-4. Make sense? (Let me know if it doesn't--I'm always willing to walk you through it some other way. I plugged it back in, and I am 100% sure that this answer is correct.)

what is the area of the science lab table that is 60 by 48 inches in feet?

Answers

2880 is the area in inches and 240 is the area in feet.
Most tables are rectangular so we can use the rectangle area formula:
[tex]A = L * W[/tex]

A = 60 * 48
A = 2880

Convert inches to feet.

2880 inches = 240 feet

So, the answer is 240 square feet.

Final answer:

The density of the brick, calculated by dividing its mass of 100g by its volume of 25cm3, is 4 g/cm³.

Explanation:

The density of a substance can be calculated using the formula density = mass/volume. In this case, the brick has a mass of 100g and a volume of 25cm3. Therefore, its density would be 100g / 25cm3 = 4 g/cm³. This means that the density of the brick is 4 grams per cubic centimeter.

Jim spends 3 1/2 days a month away from home if he does this for 6 1/2 months how many days would Jim be away from home

Answers

Final answer:

Jim would be away from home for approximately 23 days.

Explanation:

To find out how many days Jim would be away from home, we need to multiply the number of days he spends away from home in a month by the number of months he does this for:

3 1/2 days x 6 1/2 months = (7/2) x (13/2) = 91/4 = 22.75 days

Since we can't have a fraction of a day, we round up the decimal to the nearest whole number. So, Jim would be away from home for approximately 23 days.

Answers

I graphed these vertices myself in the attached photo, and it turned out to be a rectangle;  With the thought that you perhaps made a typo and meant rectangle instead of polygon I continued on and found the perimeter of the rectangle.

I counted the units of the long side (K & J) to get the length, which is 7.

Next, I counted the units between J & H to find the width which is 4.  Now we're ready to use the formula.  

First I will add the length plus the width, 7 + 4 = 11.  

Then I will multiply 2 x 11 to get a product of 22.

The grass in the outfield of a professional baseball stadium is trimmed to a height of 5.08 * 10^-5 miles. Which unit of measurement is most appropriate to measure in height?

Answers


The height is given as 5.05 x 10⁻⁵ miles.

Because this is in English units, we should reduce the height to inches.

Note that
1 mile = 5280 ft
           = 5280*12 = 63360 in

Therefore the height is
(5.08 x 10⁻⁵ miles)*(63360 in/mile) = 3.219 in

Answer:
3.2 in (nearest tenth)
The given measurement is in English units, so the conversion stays in English units.
