The length of a rectangle is three times its width. If the area of the rectangle is 243 m squared, find it’s perimeter

Answers

Answer 1

Answer: 72

Step-by-step explanation:

L= 3W

area of a rectangle  A= LxW

replace L with 3 W

A=3W*W= 3w^2

243=3W^2

243/3=W^2

81=w^2, and W=9

L=3*9=27

P= (L+W)=2(27+9)=72

Answer:

107º

Step-by-step explanation:

Okay, if 135 is adjacent to an ungiven side, then to find that, you subtract 135 from 180.

180 - 135 = 45

So the other side is 45. Now we find the last unknown given side, and since we know 180 degrees is the sum of the degrees in a triangle, we do:

28 + 45 + x = 180

73 + x = 180

Subtract 73 on both sides you get,

x = 107.

Measure DEF is 107.

According to the 2014 national population projections published by the U.S. Census Bureau, the U.S. population is projected to be 334.4 million in 2020 with an estimated growth rate of 0.79% per year. Assuming the growth rate remains constant, find the projected population in 2050.

Answers

Answer:

423,437,744

Step-by-step explanation:

Given that :

Projected population in 2020 = 334.4 million

Estimated growth rate (r) = 0.79%

Projected population in 2050 ;

Using the exponential growth function :

Estimated value = initial value(1 + growth rate)^time

Initial value = i

Time = 2020 - 2014 = 6 years

334.4 = i(1 + 0.0079)^6

334.4 = i(1.0079)^6

334.4 = i2.43087455521E−13

i = 3.189786E8

Initial population = 318. 978 million

Estimated Population in 2050:

2050 - 2014 = 36

Projected population = 3.189786E8(1.0079)^36

Projected population = 3.189786E8*1.3274801

= 423437743.82586

= 423437744 million

Answers

The decay of 277 mg of an isotope is described by the function

A(t)= 277e-0.019t,

where t is time in years.

To find the amount left after 64 years,

We substitute t = 64 in the expression.

A(t=64)= 277e-0.019(64)

or A(t=64) = 277 * e-1.216

                = 277 * 0.29

                = 82 mg

Answer:

Y = 130

X = 20

Z = 110

Answer:

y= 130 degrees  x= 20 degrees  z= 110 degrees

Step-by-step explanation:

I solved top left triangle first. So, we know all triangles add up to 180 degrees and we have two on the angles so 85 + 45 = 130 then 180 - 130 = 50 so the missing angle near y is 50. Now to figure out Y then you just subract your answer (50)  from 180 which you get 130. So y is 130 degrees. Then to figure out X, you just do 180 - 130 = 50, 50 - 30 = 20, so x is equal to 20 degrees. Then lastly to figure out z we know that the missing angle is 50 because its vertical to the other 50 degree so now you do 180 - 20 = 160, 160 - 50 = 110 degrees.

In a small private liberal arts college, 40 percent of the students receive financial aid, and 30 percent of the students that receive financial aid also are first generation college students. In addition, 25 percent of the students in the college own a hybrid car. What is the probability that a randomly selected student receives financial aid and is first generation college student

Answers

Answer:

P(A∩B) = 0.12

Step-by-step explanation:

Given:

Students receive financial aid P(A) = 40% = 0.4

Students receive financial aid and first generation P(B/A) = 30% = 0.3

Find:

Probability [Selected student receives financial aid and is first generation college student] P(A∩B)

Computation:

P(A∩B) = P(A) x P(B/A)

P(A∩B) = 0.4 x 0.3

P(A∩B) = 0.12

We conclude that for 1/2 batch, Faird would require 3/8 cups of sugar.

Step-by-step explanation:

Suger needed for a full batch = 3/4Given that Farid is making 1/2 of batch

We need to determine the expression for the amount of sugar Freed needs to make 1/2 batch.

Let 'x' be the batch and 'y' be the amount of sugar

Suger needed for a full batch = 3/4 cup of a sugar

so

x = 3/4y

But, Farid is making 1/2 of the batch.

Thus, multiply both sides by 1/2

[tex]x\times \frac{1}{2}\:=\:\frac{3}{4}y\times \frac{1}{2}[/tex]

[tex]\frac{x}{2}=\frac{3y}{8}[/tex]

Therefore, we conclude that for 1/2 batch, Faird would require 3/8 cups of sugar.

Steve's bedroom measures 12 feet by 13 feet. Ricardo's bedroom measures 8 feet by 14
feet. Assuming that both bedrooms are rectangular, whose room has the greater area?

Answers

Answer: Steve's bedroom has the greater area.

Step-by-step explanation: The formula for area is Area = Length x Width.

So all you have to do to figure this out is multiply the Width of the rooms by the length.

So Steve's room is 12ft X 13ft = 156ft

Ricardo's room is 8ft X 14ft = 112ft

156ft > 112ft

Steve's room has a greater area.

What is the exact distance from (-5,1) to (3,0).

Answers

Answer:

The distance between the two points is [tex]\sqrt{65} \ \text{units}.[/tex]

Step-by-step explanation:

In order to find the distance between two coordinate pairs, we can use the distance formula:

[tex]\displaystyle \bullet \ \ \ d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Our coordinate pairs need to be labeled accordingly, so we can use this naming system:

[tex]\bullet \ \ \ (x_1, y_1), (x_2, y_2)[/tex]

This assigns a name to our points:

[tex]x_1 = -5[/tex][tex]y_1 = 1[/tex][tex]x_2 = 3[/tex][tex]y_2 = 0[/tex]

Therefore, we can plug these into the formula and solve:

[tex]d=\sqrt{(3-(-5))^2+(0-1)^2}\\\\d=\sqrt{(8)^2+(-1)^2}\\\\d=\sqrt{8^2+1^2}\\\\d=\sqrt{64+1}\\\\d=\sqrt{65}[/tex]

Therefore, the distance between the two points is [tex]\sqrt{65} \ \text{units}[/tex].
