Answer:

Below in bold.

Step-by-step explanation:

The formula for the number of degrees in a convex polygon of side length n is   S = 180(n - 2)

Solving for n:

n - 2 = S/180

and  n = (S/180) + 2.

1.   n = (900/180) + 2 = 5 + 2 = 7 . This is a heptagon.

2.   n = (1800/180) + 2 =  12.  A duodecagon.

3.   n = (2160/180) + 2 =   14 sided polygon.

4.    n =  (2520/180) + 2 = 16 sided polygon.

5.    n = (3420/180) + 2 =  21 sided polygon.

the total time taken by Mia to complete cleaning is, 47min.

Answer:

[tex]y = -\frac{1}{2} x - 3[/tex]

Step-by-step explanation:

Answer:

f(x) = -1/2x - 3.

Step-by-step explanation:

The slope of the line = ((-7 - -5) / (8 - 4)

= -2/4

= -1/2.

y - y1 = m(x - x1)

m = -1/2, x1 = 8 and y = -7 so:

y - (-7) = -1/2(x - 8)

y + 7 = -1/2x + 4

y = -1/2x - 3.

Answer:

D) (14.10)

Step-by-step explanation:

2x -3y= -2

2. (x-y=4)2

(2x -3y= -2) 1

3. 2x-2y=8 (equation 1)

2x-3y =-2 (equation 2)

4.subtract equation 2 from equation 1 to eliminate x

5. y= 10

6. use either of the initial equations to find x eg.

x-y = 4

x- 10= 4

x = 10 + 4

x= 14

therefore x,y = 14,10

Answer:

12 pints

Step-by-step explanation:

There are 24 students & each one gets 1 cup, so you will need 24 cups total.  There are 2 cups in a pint.  You divided the 24 cups you need by 2 cups in a pint to get the answer of 12 pints.

You can double check:  12 pints converted to cups (2 cups in a pint) is 12 x2 = 24 cups

Answer:

y=4/3x+17

Step-by-step explanation:

y-y1 = m(x-x1)

m is the slope

y-9 = 4/3(x-(-6))

y-9 = 4/3(x+6)

y-9 = 4/3x+8

y-9 = 4/3x+8

y=4/3x+17

Answer:

Sherrie's method will make more money.

Step-by-step explanation:

They both deposit 300 dollars, since Harrison is compounding at 5% quarterly she will be making $15 every quarter and since there are 4 quarters per yr at the end of the year Harrison will be sitting at $360.

Whereas Sherrie is compounding at 3% per month so she will be making $9 per month and multiply that by 12 she will be sitting at $408 by the end of the year hence Sherrie makes more.

Using proportions, it is found that he should collect 80 signatures in each week.

A proportion is a fraction of a total amount.

He currently has 520 signatures, and needs 1000, hence he needs to collect more 1000 - 520 = 480 signatures.

He has six weeks to collect the signatures, hence the number he needs to collect each week is given by:

N = 480/6 = 80.

Answer: True

Step-by-step explanation:

It passes the vertical line test, no two points are on the same x value

Correct option is A .True . The given graph is of a function by vertical line test

The vertical line test is a test that checks whether a  given graph is of a function or not. It states that every vertical line passing through the given graph should intersect the graph at most one point .( which comes from the definition of function that that a function takes every point in the input set to a unique image in the codomain set)

For the given graph whenever we will draw a vertical line passing through any point on the domain then it will cut the graph at one point only this can be seen in the attached figure.

Therefore, its true that the given graph represents a function.

∴Correct option is A. True.

Answer:

Step-by-step explanation:

barrier = parameter, so we add all the sides:

8+3+3+5+5 = 24

24*1.75 = $42.

THEN, we need the area to solve for the mulch.

I would split it up into two parts so the rectangle and then the triangle.

First, 8*3 is 24

now we divide this by four because one bag covers four square feet

so, 6 bags (24/4=6) which is $36 (6*$6).

_______________

Now, the triangle, which a = (hb*b)/2

12 divided by four again so 3

3 * 6 = $18.

Now we add ALL costs up to get

42+36+18 = $96 total for the entire project.

Answer:

17 degrees

Step-by-step explanation:

See attached image.

We conclude that the angle at the top measures 65.8°.

The whole tree measures 117 ft, and it is broken 34 ft above the ground, forming this way a right triangle.

Then one cathetus of the right triangle measures 34ft, and the hypotenuse measures 117ft - 34ft = 83ft

The angle at the top is θ, the adjacent cathetus to it is the one that measures 34 ft, then to get the angle we can use the relation:

cos(θ) = (adjacent cathetus)/(hypotenuse)

Replacing what we know, we get:

cos(θ) = (34 ft)/(83ft) = 34/83

Solving for θ, we get:

θ = Acos( 34/83) = 65.8°

So we conclude that the angle at the top measures 65.8°.

Answer:

x= 1/10

Step-by-step explanation:

First, factor out the common term of 2:

2(4-x)/3 - 2x-3/2 = 4

Multiply both sides by 6(the LCM of 2,3):

4(4-x) - 3(2x-3) = 24

Distribute:

16-4x - 6x + 9 =24

Add like terms:

25-10x=24

Subtract 25 from both sides:

25-10x(-25) = 24-25

-10x=-1

Divide by -10:

-10x/-10 = -1/-10

Solve for x:

x= 1/10
