Answer:

[8] Area is = to 1017.36            Circumference is = to 113.04

[9] Area is = 490.625             Circumference is = 78.5

[10] D  = 16                                R = 8

Step-by-step explanation:

[8]

Area is = to 1017.36

Circumference is = to 113.04

<u>Formula:</u>

Area = πr²

Circumference = 2πr

<u><em>Solve:</em></u>

A =  πr²

A = 3.14(18) ²

A = 3.14(324)

A = 1017.36

C= 2πr

C = 2(3.14)(18)

C = 113.04

Area = 490.625

Circumference is = 78.5

<u>Formula:</u>

Area = πr²

Circumference = 2πr

<u><em>Solve:</em></u>

Area = πr²

A = 3.14(12.5)²

A = 3.14(156.25)

A = 490.625

Circumference = 2πr

C = 2(3.14)(12.5)

C = 78.5

Circle area = π * r² = π * 64 [cm²] ≈ 201.06 [cm²]

π ≈ 3.14159265 ≈ 3.14

d = r * 2 = 8 [cm] * 2 = 16 [cm]

Which point is located at 5_2​
alexdok [17]

Hey there!

Point D is located at point (5, -2)

In coordinates, the first number represents the x-coordinate, and the second number represents the y-coordinate. (TIP: YOU MUST START AT THE ORIGIN, OR (0, 0). In the x-coordinate, you go left/right that number of spaces, left for negative and right for positive. For the y-coordinate, you go up/down that number of spaces, down for negative and up for positive. This means that the point (5, -2) is 5 units right and 2 units down, which lands on point D.

Hope it helps and have an amazing day!

Find the equation of the line passing through the point (4,−1) that is parallel to the line 2x−3y=9.
motikmotik

Hey there!

Line passes through (4, -1) & is parallel to 2x -3y=9

Let's start off by identifying what our slope is. In the slope-intercept form y=mx+b, we know that "m" is our slope.

The given equation needs to be converted into slope-intercept form and we can do this by getting y onto its own side of the equal sign.

Start off by subtracting 2x from both sides.

-3y = -2x + 9

Then, divide both sides by -3.

y = (-2x + 9)/-3

Simplify.

y = 2/3x - 3

"M" is simply a place mat so if we look at our given line, the "m" value is 2/3. Therefore, our slope is 2/3.

We should also note that we're looking for a line that's parallel to the given one. This means that our new line has the same slope as our given line. Therefore, our new line has a slope of 2/3.

Now, we use point-slope form ( y-y₁=m(x-x₁) ) to complete our task of finding a line that passes through (4, -1). Our new slope is 2/3 & it passes through (4, -1).

y-y₁=m(x-x₁)

Let's start by plugging in 2/3 for m (our new slope), 4 for x1 and -1 for y1.

y - (-1) = 2/3(x - 4)

Simplify.

y + 1 = 2/3 + 8/3

Simplify by subtracting 1 from both sides.

y = 2/3x + 8/3 - 1

Simplify.

y = 2/3x + 5/3

~Hope I helped!~

A children's birthday party at a indoor play center cost $50 to rent the space and 6.25 per child. Gina wants to spend no more t
scZoUnD [109]

Answer:

The number of children (n) that can attend the birthday party can be expressed as;

n≤8

Step-by-step explanation:

Step 1

We can use the expression below to calculate the total cost of the party as shown;

C≥F+(V×n)

where;

C=total cost of Gina is willing to spend

F=fixed cost for the rent

V=cost per child

n=number of children at the party

In our case;

C=$100

F=$50

V=$6.25

n=n

replacing;

100≥50+(6.25×n)

6.25 n+50≤100

6.25 n≤100-50

6.25 n≤50

n≤50/6.25

n≤8

The number of children (n) that can attend the birthday party can be expressed as;

n≤8

Aleks [24]

Answer:

No

Step-by-step explanation:

The relationship between the number of pies and the cost is not proportional. This is because the third pie is at half price, meaning it's not consistent with the price of the other two.
