The length of a rectangle is three times it’s width. It’s area is 75 inches squared. Find the length and width of the rectangle

Answers

Answer 1

The answer is 225 because 75x3 =225



Answer 2

Final answer:

The length of the rectangle is 15 inches and the width is 5 inches, determined by setting up an equation using the given conditions that the area is 75 square inches and the length is three times the width.

Explanation:

The question asks us to find the length and width of a rectangle given that the length is three times the width and the area of the rectangle is 75 square inches. To solve this, let's denote the width of the rectangle as w inches. The length would then be 3w inches since it is three times the width. The area of a rectangle is found by multiplying the length and width, so we can write the equation:

Area = length × width

75 = 3w × w

To find the width (w), we need to solve the quadratic equation:

w² × 3 = 75

w² = 75 / 3

w² = 25

To find w, we take the square root of 25, which gives us:

w = 5 inches

Now that we have the width, we can easily find the length by multiplying the width by 3:

Length = 3 × 5

Length = 15 inches

Therefore, the width of the rectangle is 5 inches and the length is 15 inches.

the cost of 500000 worth of 30 year term life insurance for Edna is $121.04 per month if Edna's employer covers 80% of this cost how much is deducted from Edna's gross income per year for life insurance?

Answers

121.04×.80=96.83
96.83×12=1161.96
Ednas employer pays 1161.96
121.04-96.83=24.21
24.21×12=290.52
Edna pays $290.52 of her gross income

Answer:

$290.50

Step-by-step explanation:

121.04 * 80% = 96.832

121.04 - 96.832 = 24.208

24.208 * 12 = 290.496 ~ 290.50

Greta uses 6 ounces of pasta to make 6 /7 of a serving of pasta. How many ounces of pasta are there per serving?

Answers

Answer:

7

Step-by-step explanation:

We know that since 6 ounces creates 6/7 of a serving, that basically says that 1/7 of a serving is created with 1 ounce of pasta. So if there were 7 ounces of pasta, that would make 7/7 servings and that would be 1 serving

An airplane started at 0 feet. It rose 21000 feet at takeoff. It then descended 4329 feet because of clouds. After the oncoming plane passed, it descended 8453 feet, at what altitude was the plane flying?

Answers

The fact that an oncoming plane passed is irrelevant to what we need to find, so we can ignore that.

The math statement it's asking you to solve is this:

0+21000-(4329+8543)

The reason we are adding 4329 and 8543 is to make it easier on the subtraction. Since both of those terms are being subtracted, we can combine them to make our problem one step shorter.

After simplifying the parentheses, we get:

21000-12872

After this it becomes simple subtraction to find the answer.

8128 is the answer, so your answer would be:

The plane is now flying at an altitude of 8,128 feet.

Answer:

Ur answer is

The plane was flying at 8,218 feet altitude

Step-by-step explanation:

This is easy u start off with 21,000 then subtract as needed

21,000-4329=16,671

16,671-8,453=8,218

So ur answer is 8,218

A new sidewalk will be 5 feet wide, 240 feet long, and filled to a depth of 9 inches (0.75) with concrete. How many cubic yards of concrete are needed?

Answers

In order to build the sidewalk, they would need around 33  yrds^3 of concrete. This is because the problem is asking for the volume of the sidewalk. First, we need to convert everything into yards. The final answers we would get would be (5/3) (80) and (0.25). If we were to use the formula for volume, it would be V=lwh. With that incorporated, the answer would be 33.3333333 yrds^3 of concrete to be exact.

Final answer:

The volume of the sidewalk can be calculated using the formula for the volume of a rectangular prism, V = length x width x depth. The volume in cubic feet is then converted to cubic yards as concrete is sold in cubic yards. Therefore, approximately 33.3 cubic yards of concrete are needed for the sidewalk.

Explanation:

To calculate the amount of concrete needed for a sidewalk, we first need to find the volume of this sidewalk in cubic feet and then convert it to cubic yards because concrete is usually sold in cubic yards. The given dimensions of the sidewalk are 5 feet wide, 240 feet long, and a depth of 0.75 feet (9 inches).

The volume (V) of a rectangular prism (which in this case is the sidewalk) can be calculated using the formula V = length x width x depth. Therefore, V = 5 ft (width) x 240 ft (length) x 0.75 ft (depth) which gives us 900 cubic feet.

Next, we need to convert cubic feet to cubic yards because concrete is sold in cubic yards. One cubic yard is equivalent to 27 cubic feet. Therefore, the volume of concrete in cubic yards is 900 cubic feet ÷ 27 = 33.3 cubic yards. So, you will need approximately 33.3 cubic yards of concrete to build this sidewalk.

A play is performed for a crowd of 400 people. Adult tickets cost $22 each, student tickets cost $15 each, and tickets for children cost $13.50 each. The revenue for the concert is $7840. There are 40 more children at the concert than students. How many of each type of ticket are sold?

Answers

Answer:

280 adult tickets, 40 student tickets and 80 children tickets were sold.

Step-by-step explanation:

To solve this problem let's call:

x = number of tickets for adults

y = number of tickets for students

z = number of tickets for children

The income for the concert is $ 7840

Then we can raise the following equations according to the given conditions:

[tex]x+y+z = 400[/tex]   (i)

[tex]22x+15y +13.50z = 7840[/tex] (ii)

 There are 40 more children in the concert than students:

So:

[tex]z=40+y[/tex]  (iii)

We then have 3 equations and 3 unknowns:

To solve the system we multiply the equation (i) by -22 and add it to the equation (ii)

So:

[tex]-22x-22y-22z=-8800[/tex]

       +

[tex]22x+15y +13.5z =7840 [/tex]

[tex]-7y-8.5z = -960[/tex] (iv)

 Now we multiply (iii) by 7 and add it to (iv)

[tex]7y-7z = -280 [/tex]

   +

[tex]-7y-8.5z = -960[/tex]    

[tex]-15.5z = -1240 [/tex]

[tex]z = 80[/tex] (v)

We substitute (v) in (iv) and we have

[tex]y = 40[/tex] (vi)

We substitute (v) and (vi) into (i) and we have:

[tex]x =280[/tex]

if 14 giant solar power plants generate 2.6 gigawatts of energy to power 1.8 million homes how many homes can 28 solar panels power

Answers

Doubling the number of giant solar power calculation plants from 14 to 28 would theoretically power double the number of homes, which is approximately 257,142 homes.

If 14 giant solar power plants generate 2.6 gigawatts of energy to power 1.8 million homes, we can calculate the number of homes that 28 solar panels can power by first determining the number of homes one plant can supply energy for.

Powering 1.8 million homes with 14 plants means each plant powers 1.8 million / 14 = 128,571 homes approximately.

If we assume a direct scale-up, doubling the number of solar power plants to 28 would theoretically double the number of homes that can be powered, hence 28 plants would power 128,571 homes × 2 = 257,142 homes approximately.

However, the question seems to have a typo because usually power capacity is specified for power plants and not individual solar panels.

So, doubling the number of solar panels, not power plants, wouldn't necessarily mean doubling the total power capacity because individual solar panels have a much smaller capacity than an entire power plant.

Rule 1:

If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40.

Rule 2:

If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down.

We are given the number 13_,644 which rounds off to 130,000.

Now as we can see the number is rounded down, so we can apply rule number 2 here.

There was a beautiful Japanese garden. Within the garden, there is a pond. Since the beginning of summer, lilies have started to cover more and more of it with every passing day. In fact, the quantity of lilies doubles every day. By day 58, the entire pond will be covered. How many days will it take the lilies to cover half the pond?

Answers

Answer:

57 days

Step-by-step explanation:

Given that there was a beautiful Japanese garden.

Also given that within the garden, there is a pond.

Since the beginning of summer, lilies have started to cover more and more of it with every passing day.

In fact, the quantity of lilies doubles every day.

By day 58, the entire pond will be covered.

Since given that every day lilies double, we find that if on 58th day it was full, then exactly one day before it should be 1/2 of pond.  In that case only, on 58th day pond can become full.

Hence half pond is filled with lilies in 57 days.

33 more than the smallest number is written as x+33


Now you have:

x + x+1 + x+2 = x+33

Simplify the left side:

3x +3 = x +33

Subtract 3 from each side:

3x = x +30

Subtract 1x from each side:

2x = 30

Divide both sides by 2:

X = 30/2
