Answer 1

Answer:

1) E

2) D

3) G

4) I

Step-by-step explanation:

P = 2(l + w)

P = 2(3a + 3 + 8a - 12)

P = 2(11a - 9)

P = 22a - 18

P = 22(3) - 18

P = 66 - 18

P = 48

P = a + b + c

P = 3b + 7 + 7b - 2 + 7b - 2

P = 17b + 3

P = 17(6) + 3

P = 102 + 3

P = 105

The current population of Rochester is 211,000 and is decreasing at a rate of 4.1% every ten years. Which function can be used to find the population 30 years from now?

Answers

Answer:

211,000(0.97)t

Step-by-step explanation:

Firstly; Write the exponential decay function for this situation.

y = a(1 – r)t Write the formula.

= 211,000(1 – 0.041)t Substitute 1700 for a and 0.03 for r.

= 211,000(0.97)t Simplify.

Next; Find the population in function.

y = 1700 Substitute 12 for t.

≈ 1180 Use a calculator and round to the nearest whole number.

The population in 30 years function will be approximately 211,000(0.97)t.

Answers

Answer:

The angle of the unknown measure is 27°.

Step-by-step explanation:

When we look at this angle, we can see it is a 90° angle. Since we already have 63° of the angle, we just subtract 90° from 63° and we get 27°. Therefore, 27° is our answer.

HELP NO LINKS Jesse wants to start driving himself to and from school each day his parents want to know how much driving time would be involved so Jesse surveyed for neighbors who live on his block and drive to school data he collected is displayed in the table below

Answers

the answer is B. have a good thanksgiving

175 minutes of driving time would be involved for Jesse according to the survey.

What are the basic rules of surveying?

Some basic rules of surveying are:

Define a clear, attainable goal for your survey.Keep the more personal questions to the end. Don't let your survey get too long. Focus on using closed-ended questions. Consider including a survey incentive. Don't ask leading questions. Keep your answer choices balanced

Given, Jese wants to start driving himself to and from school each day He surveyed neighbors who live on his block and drive to school data.

For better understanding, a picture is attached below.

Add up the 8 different times then divide by 4 to get the average driving time for 1 day:

⇒ 12 + 18 + 13 + 21 + 15 + 22 + 15 + 22 = 138

⇒ 138 ÷ 4 = 34.5 mins

Now multiply the average drive time for 1 day by 5 to determine the time taken to drive to and from school for 5 days:

⇒ 34.5 x 5 = 172.5 minutes

As 172.5 ≈ 175 minutes, the nest response is 175 minutes

Therefore, According to the study, Jesse would require 175 minutes of driving time.

what would I put to show my work?

Answers

Answer:

x = 23

Step-by-step explanation:

These are supplementary angles so the sum of those angles add up to 180:

3x + 16 + 5x - 20 = 180

8x - 4 = 180

8x = 180 + 4

8x = 184

x = 184/8

Answers

Answer:

y=x/3 - 4

Step-by-step explanation:

add x to get x to the other side

3y= x-12

divide by 3 on both sides to get y by itself y= x/3 - 4 is simplest form

Answer:

slope intercept form is y=mx+b

add x to both sides : 3y=x-12

divide by 3 on both sides : y=(1/3)x-4

If a rectangular cross-section with coordinates at (1, 1), (1, 4), (3, 4) and (3, 1) is rotated about the line y = 1, what will be the resulting three-dimensional object?

Answers

Answer:

cylinder

Step-by-step explanation:

Answer

cylinder!!

Step-by-step explanation:

so the points "(1, 1), (1, 4), (3, 4) and (3, 1)" they are all positive so this makes this easier tbh so it looks like this once u put them on a grah

. .

its a rectangle then it says to rotate on y = 1 which u look at the graph u just put this rectangle on its side like this

. .

so then look at the answer options

A.) Cone

B.)Cylinder

C.)Sphere

D.)Pyramid

so it CANT be A bc 1 its a rectangle and if it was a cone it would have 3 points, not 4, bc it would be a triangle

It can be B bc on a graph it will be 2D and a Cylinder has 4 points on a graph(in 2D) which the problem is telling you to make something 2D into something 3D...and is a rectangle in 2D

It CANT be a C bc in 2D it would be a circle and straight up, a square isnt a circle, and the points on the problem is a square ant there would be so many points to put down if it was a circle

It CANT be a D bc once again this would be a triangle and that would have 3 points, or maybe 5(if your looking overhead of the Pyramid where u can see all 4 corners, like a square then the middle point) so a square has all equal sides, rectagle does not, it has 2 and 2 equal sides. 2 sides being small and paralell, and 2 long sides being parallel.

:) have a good day

btw answer is

cylinder!!
