1) the equation for finding the perimeter of a rectangle is P=2L+2W. so, P=2(120)+2(53). P=240+106. P=346.

2) The equation is P=2L+2W. P=2(3)+2(2). P=6+4. P=10

3) the equation for finding the perimeter of a square is P=4s. So P=4(15) P=60

the division problem is 7 divided by 15. this can be written as 7/15. to do this, you first know that 15 doesn't go into 7, so you add a decimal point, and make the 7 70. 15 goes into 70 4 times. 15 times 4 is 60. 70-60 is 10. 15 doesn't go into 10, so you add another 0 and bring it down. 15 goes into 100 6 times. 15 times 6 is 90. 100-90 is 10. 15 doesn't go into 10, so you bring down another 0. 15 goes into 100 6 times. 15 times 6 is 90. 100-90 is 10. at this point, you can probably guess that the 6 will go on for a while. this means it is repeating. this means your answer is "a".

C. Two along the x-axis, and one along the y-axis
D. Tel along the x-axis, and two along the y-axis

Answers

The variables displayed in a scatter plot are: (a) one along the x-axis, and one along the y-axis

The variables of a scatter plot are the quantities whose correlation is being determined

In a scatter plot, they are always two variables.

One is placed on the x-axis, while the other is on the y-axis

Hence, the variables displayed in a scatter plot are: (a) one along the x-axis, and one along the y-axis

Two cars are traveling down the highway at the same speed. If the first car increases its speed by 10 kilometers per hour, and the second car decreases its speed by 10 kilometers per hour, then the first car will travel the same distance in two hours that the second car travels in three hours. What is the original speed of the cars?

Answers

Answer:

50mph

Step-by-step explanation:

Say for example car A increases by 10 miles per hour and car B decreases by 10 miles per hour. If car A2 = car B3 then by eliminating a few numbers and finally get to 50 you get the following equation.

A = 50+10

b = 50-10

A = 60

B = 40

A2 = 120

B3 = 120

120 = 120

Answer

50 mph

Step-by-step explanation:

3(s-10)=2(s+10)

A. Are the expressions 3(m−2) + 2(m−2) and 5(m−2) equivalent expressions?

B. In two or more complete sentences, justify your answer to A.

Answers

The answer is yes. If you solve both expressions it would be 5m-10.

Answer: yes, this is because when you solve the first equation then your answer will be 5(m-2). You do this by distributing 3 to m & 2 (multiply), then you will distribute 2 to m & 2 (also multiply).

Step-by-step explanation:

pls help !! will give brainilest

Answers

it’s a linear function so,

y = mx+b

b is 0.

m is rise/run, which is 6/3, which is 2.

so

y=2x

hope this helps!

Answer:

y = 2x

Step-by-step explanation:

the equation of proportional relationships are in the form y = mx, where m is the slope.

this means you need to solve the slope.

to find the slope, find 2 random points and do change in y divided by change in x.

for example, (3, 6) and (0, 0)

this would be (6 - 0)/(3 - 0) = 2

this means m = 2

so the equation is y = 2x

which is shorter 8ft or 95in !?

Answers

95 inches is shorter

Answer: 95 in is shorter

there are 12 in in a foot, so in that case you have to divide 95 in by 12. The answer is 7.91666667 but if you round it up you would get 8, which that is = 8ft but without rounding it up you would get 7.9ft which is less than 8ft. so the answer is 95 in is shorter than 8ft

Find the approximate radius of a circle with an area of 16 cm2.

Answers

Answer:

radius (r)= 2.25

Step-by-step explanation:

√5.09= r

r=2.25

What fraction is represented by Point A?

Point A is at
.

Which point represents 5
6
?

Point
represents 5
6
.

Answers

Answer:

The number line is divided by 6ths.

Step-by-step explanation:

There are 6 equally sized spaces between 0 and 1 on a number line. By definition of a fraction, a quantity is divided upon a number of equal parts in which can be expressed as the number of parts divided by the total number of parts. Therefore, the numerator in this case will be how many of the 6 parts are there at a certain point; the denominator will be 6, since there are 6 total, equal parts. In this case, think of the fraction as a distance traveled from 0 to 1 in 6 parts; the numerator is how far is traveled, and the denominator is the total travel distance. Point A is located at 1/6, since it is 1 out of the 6 pieces traveled. Point D would be at 5/6 because it has traveled 5 out of the 6 distances.

Point A is at

✔ 1/6

Point

✔ D

A washing machine is filling up with water at a constant rate. The rate is Three-fourths of a gallon in 1 over 5 of a minute. Don calculated the unit rate to be 3 over 20 of a gallon per minute. What did he do wrong?

Answers

Answer:

First, you have to see how many gallons fill in a minute, obviously, so take 3/4 and divide it by 1/5, which gives 15/4. so you can see, don multiplied the two numbers instead of dividing, which is what he did wrong.Step-by-step explanation:

Answer from NukeExplosions1

Answer:

What he did wrong is that he multiplied the denominator wrong. it is supposed to be a 15. Don should re-calculate it to 3 over 15 of a gallon per minute.
