A circular rug has a diameter of 18 ft. What is the area of the rug? Use 3.14 for T.
Record your answer on the grid. Then fill in the bubbles.

Answers

Answer 1
Answer = 254.34 ft squared

Area of a circle = pi x r squared

It says to take pi as 3.14

R = Half of the diameter = 9 ft

R squared = 9 squared = 81 ft

3.14 x 81 = 254.34

By working 8 hours per day, Marley's team can complete a task in 15.5 days. Bill's team works on the same task at the same speed; however, Bill's team works 7 hours and 45 minutes per day. How many days does it take Bill's team to complete the task?

Answers

It will take 16 days.
8 Hours x 15.5 days = 124 Hours

Using this logic, we know 60 minutes in an hour and 45/60= .75. So it is 7.75 Hours.
124/7.75= 16.

Hope this helps :)
The ratio of numbers of days required is the reciprocal of the ratio of the number of hours worked per day. Think of examples with easier numbers: if you work on a project 4 hours a day, it will take you 2 times as long as if you work 8 hours a day.

ratio of hours worked per day: 7 3/4 to 8 = 31 to 32
ratio of number of days required: 32:31
number of days required by Bill's team: 15.5%2A%2832%2F31%29+=+%2831%2F2%29%2A%2832%2F31%29+=+32%2F2+=+16

Diane knows a phone call to a friend costs 25 cents for the first 3 minutes and 10 cents for each additional minute. The number of minutes you call and the cost of the call are related.

Diane knows a phone call to a friend costs 25 cents for the first 3 minutes and 10 cents for each additional

Answers

It should be y=.10x + .25 because for each additional minute you are adding 10 cents to ur total cost and then u add the 25 cents to ur amount because that’s how much it costs to make the call for the first 3 minutes.

The correct equation for total amount is,

y = 10x + 75

We have to given that,

Diane knows a phone call to a friend costs 25 cents for the first 3 minutes and 10 cents for each additional minute.

Here, The number of minutes you call and the cost of the call are related.

Now, Let us assume that,

Number of additional minutes = x

Hence, The correct equation for total amount is,

y = 25 × 3 + 10x

y = 75 + 10x

y = 10x + 75

Hence, The graph of equation shown in figure.

Which pairs of numbers are the same distance apart as 2.9 and 3.8? Select all that apply. A 0 and 0.8 B 0 and 0.9 C 1.0 and 1.9 D 1.8 and 2.9 E 1.9 and 2.8

Answers

Answer:

subtract 2.9 from 3.8 you get 0.9

subtract 1.0 from 1.9 you get 0.9

subtract 1.9 from 2.8 you get 0.9

subtract 1.8 from 2.9 you get 01.1

I would say that your answers are E, C, and B.

Answer:

B, C, and E

Step-by-step explanation:

If you subtract 2.9 from 3.8 you get 0.9 so if u apply that to B, C, and E, you could add 0.9 to 0, 1.0, and 1.9 and get the equations:

0+0.9= 0.9

1.0+0.9= 1.9

1.9+0.9= 2.8

so as you can see it all just increases by 0.9 every time.

The library loans 4 times as many non-fiction books as it does
fiction books. Write a rule for the relationship between the two
variables. Use n for non-fiction and f for fiction.

Answers

N * 4 =f
We know there are 4 times as many non-fiction books as there are fiction books so we would have to multiply non-fiction by 4 to figure out how many fiction books there are

The rule for the relationship between the nonfiction and fiction books as an expression is n = 4f.

We have,

Let's write a rule for the relationship between the number of non-fiction books (n) and the number of fiction books (f) based on the given information.

We are told that the library loans 4 times as many non-fiction books as it does fiction books.

This means that the number of non-fiction books (n) is equal to 4 times the number of fiction books (f).

Mathematically, we can express this relationship as:

n = 4f

Where:

n = Number of non-fiction books

f = Number of fiction books

Thus,

The rule for the relationship between the nonfiction and fiction books as an expression is n = 4f.

How many quadrants plane have a positive x-value?

Answers

Answer:

2

Step-by-step explanation:Quadrant I and Quadrant IV

Two out of the four Quadrant planes have a positive x- value.

The coordinate axis split the plane into four parts called Quadrants or which can also be called Cartesian quadrants. These divided parts of the plane are numbered I, II, III, and IV.

The first quadrant/ quadrant I which lies on the upper axis on the right side of the plane has two positive quadrants, that is one positive x and one positive y because both of them lie in the positive direction of the axis.

The second quadrant/ quadrant II which appears on the upper right side of the plane has one positive and one negative coordinate that is, one positive y and one negative x because the x coordinate lie in the opposite direction of the sign of the numbers.

In quadrant III which lies in the downward direction and the left side of the plane has two negative coordinates both x and y. both the coordinates go towards the opposite direction of the sign convention.

in the last quadrant/ quadrant IV have a positive x- coordinate and one negative y-coordinate. Because the y coordinate goes against the positive sign convention.

75 > 30

what value of x makes this equation true -(x+3)=2(x-3)

A. 0
B. 1
C. 2
D. 3

Answers

Answer:

To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:

Step 1: Distribute the negative sign on the left side of the equation:

-(x + 3) = 2(x - 3)

=> -x - 3 = 2(x - 3) (using the distributive property)

Step 2: Expand the right side of the equation:

-x - 3 = 2x - 6

Step 3: Add x to both sides of the equation to isolate the x term on one side:

-x + x - 3 = 2x + x - 6

=> -3 = 3x - 6

Step 4: Add 6 to both sides of the equation:

-3 + 6 = 3x - 6 + 6

=> 3 = 3x

Step 5: Divide both sides of the equation by 3 to solve for x:

3/3 = 3x/3

=> 1 = x

So, the correct value of x that makes the equation true is B. 1.

PLEASE MARK BRAILYISTT :D

Answer:

B, one

Step-by-step explanation:

In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6. If you make the variables on one side and the constants on the other, you will get -3x-3=-6. This can further simplify to -3x=-6. Divide both sides by -3 to get that x=1. Then, the correct answer is B.

Solve the linear equation 17 - x = ⅓ times 15 + 6. State the property that justifies your first step and why you chose it.

Answer:

The simplified expression is 1/w^6.

Step-by-step explanation:

Using the product of powers exponent rule, we have

w^3 * w^(-9) = w^(3 + (-9)) = w^(-6).

However, the problem says to write the expression using only positive exponents. Here's an example of how to interpret negative exponents as positive exponents:

3^2 = 9

3^1 = 3

3^0 = 1

3^(-1) = 1/3

(and keeps on dividing by three onward)

Here, we see that 3^(-1) = 1/3^1.

Applying the same logic here, we have

w^(-6) = 1/w^6.

Help pls. Also wdym this is to short yk why so long &gt;:/

Answers

Answer:

Y= mx + b

so Y = 1/3x + 2

just substitute

Due to the answer requesting slope intercept form, one shall use the points (3,2) in order to substitute for b. Slope intercept form is formatted in y = mx + b, which m would be your slope, which in this particular problem was given; therefore, y = 1/3x +b.


Now, we shall use points (3,2) as the substitutes for the solution for b, which 3 would be the input and 2 would be y.


Therefore, 2 = 1/3(3) + b
2 = 1 + b, therefore, one would be subtracted from 2 which would give us the answer of b equaling to one. Thus, y = 1/3x + 1

The cost y (in dollars) to rent a lane at the bowling alley is proportional to the number x of hours that you rent the lane. It costs $18 to rent the lane for 2 hours.
a) Write an equation that represents the situation
b) Interpret the slope
c)How much does it cost to rent the lane for 3 hours?

Answers

Answer:

a) y = 9x

b) For every increase of 1 hour the price to rent the lane increases by $9.

c) $27

Step-by-step explanation:

a) Since it costs $18 for 2 hours we can infer that for every 1 hour it costs $9.

So, the equation would look like this:

y = 9x

b) In this context, for every increase of 1 hour the price to rent the lane increases by $9. Like the question gave us, the price for 2 hours cost $18.

c) Plug 3 into the equation:

y = 9(3)

y = 27

Therefore, it costs $27 to rent the lane for 3 hours.

I hope this helps!!

Laurel needs blank feet of fencing.

Answers

Answer:

294.5 Square feet

Step-by-step explanation:

50*4=200, as the garden is a square which has 4 sides. Then we have to add 10.5*3=31.5 for each bed as they will be added in too. so 200+94.5=294.5 square feet

Laurel needs 326 feet of fencing

Explanation:
50×4 = 200 for the square garden Then 5×4 = 42 for one rose bed Then 42×3 = 126 for all 3 rose beds then 200(square garden)+126(all rose beds) = 326(total fencing)
