The length of a rectangle is 5 cm longer than its width.
If the perimeter of the rectangle is 30 cm, find its area.

Answers

Equation To write :2 {x+ ( x+5) }=30

Let's solve your equation step-by-step.

2(x+x+5)=30

Step 1: Simplify both sides of the equation.

2(x+x+5)=30

(2)(x)+(2)(x)+(2)(5)=30(Distribute)

2x+2x+10=30

(2x+2x)+(10)=30(Combine Like Terms)

4x+10=30

4x+10=30

Step 2: Subtract 10 from both sides.

4x+10−10=30−10

4x=20

Step 3: Divide both sides by 4.

4x

4

=

20

4

x=5

So... x+5=10.

Area =5x10=50 cm squared.

Answer:

5

Step-by-step explanation:

Okay, so P = perimeter, and the problem says P = 30

 Let's call x the width, and y is the length.

 

In the perimeter formula, 2X + 2Y = P

so 2X + 2Y = 30

The problem also tells us that that x = y+5, so now let's do some substituting and replace X with Y+5

 2(y+5) + 2Y = 30

2y+10 +2Y = 30

4y+10=30

-10. -10

4y=20

Y=5

Which box plot could represent this data?

Answers

Answer:

First box plot

Step-by-step explanation:

In the figure attached, the options are shown.

The left end of the box is the lower quartile (also called quartile 1 or Q1)

The right end of the box is the upper quartile (also called quartile 3 or Q3)}

The interquartile range (IQR) is computed as follows:

IQR = Q3 - Q1

If Q1 = 3 and IQR = 5, then Q3 = 5 + 3 = 8

The first box plot is the only one with a lower quartile of 3 and an interquartile range of 5

The box plot that could represent a data set that has an interquartile range of 5 is the box plot shown in the image attached below (see attachment).

What is Interquartile Range (IQR)?

Interquartile range (IQR) of a data set is the distance between the lower quartile (Q1) and the upper quartile (Q3) on a box plot.

Thus, a box plot that has a lower quartile of 3 and interquartile range of 5 will have a distance of 5 from the lower quartile to the upper quartile.

Therefore, the box plot that could represent a data set that has an interquartile range of 5 is the box plot shown in the image attached below (see attachment).

How many of


age in years

the applicants have ages that fall within the box of the box plot?


Please help!!!!

Answers

Answer:

The number of applicants that have ages that fall within the box of the boxplot = 10.

Step-by-step explanation:

box plot is constructed from five values: the minimum value, the first quartile, the median, the third quartile, and the maximum value.

The boxplot usually consists of a box and a whisker plot.

The whiskers represent data that is less than the first quartile or 25th percentile and data that is more than the third quartile or 75th percentile.

The box of the boxplot is bounded by the first quartile or 25th percentile and the third quartile or 75th percentile.

Hence, the fraction of the distribution that is usually contained in the box of the boxplot is (75 - 25), 50% of the distribution.

The total number of applicants = 20

50% of 20 = 10.

Hence, the number of applicants that have ages that fall within the box of the boxplot = 10

Step-by-step explanation:

it makes sence for the answer to be a because

Answer:

The amount of carbon in the trees and in the deer . . .

A) has increased.

Explanation:

Carbon is the basis for all living cells, it is responsible for the making and storing of energy. So if the number of energy storage molecules increases, the amount of carbon will increase because carbon is used to make those molecules.

Your question on carbon dioxide and photosynthesis having an effect is valid, but the loss of carbon wouldn't be much compared to the energy storage molecules, so we wouldn't consider that a factor in this case.

Answer:

x = 3 1/3

Step-by-step explanation:

Let's go over the order of operations.

P: Parentheses

E: Exponents

M/D: Multiplication/division (in order of appearance)

A/S: Addition/Subtraction (in order of appearance)

100 = 5*(4 + 2)

Since there are values in parentheses, solve those first: 100 .= 5x(6).

Next, multiply 5x by 6. 100 = 30x.

Finally, divide each side by 30 to find the value of x. 3 1/3 = x

Therefore, the value of x is 3 1/3.

A friend bought 2 boxes of pencils and 8 notebooks for school, and it cost him $11. He went back to the store the same day to buy supplies for his younger brother. He spent $11.25 on 3 boxes of pencils and 5 notenooks. How much would 9 notebooks cost?

Answers

Answer:

9 notebooks would cost $6.75

Step-by-step explanation:

How I solved this problem was by taking the data and writing it out first.

During one trip, he got 2 boxes of pencils and 8 notebooks for $11.00

During the second trip, he got 3 boxes of pencils and 5 notebooks for $11.25

This led me to believe that the boxes were definitely more expensive than the notebooks, as there were many notebooks bought during the first trip, yet that trip was cheaper than the second. So, by the process of elimination, I started off the value of the notebooks to be $0.50, and the boxes of pencils to be $3.00, and I continued to experiment with values until I found two values that would work in both scenarios, the values being $2.50 for a box of pencils, and $0.75 for a notebook. (I know there's likely an easier way of doing this, but I haven't done a problem like this in a while, and this method works just fine. It's just a bit more time consuming.)

1st Case: 2(2.50) + 8(0.75) = 11

2 times 2.50 equals 5, and 8 times 0.75 equals 6. 5 added to 6 gives you a sum of 11.

2nd Case: 3(2.50) + 5(0.75) = 11.25

3 times 2.50 equals 7.50, and 5 times 0.75 equals 3.75. 7.50 added to 3.75 gives you a sum of 11.25

Now that it is known how much each notebook costs ($0.75), you would take that value and multiply it by 9, since you're wanting to know how many 9 would cost, and this gives you a product of $6.75.

I hope this helps :)
