Perimeter = 2 × 3.14 × 9

Perimeter = 56.52

Perimeter = 56.52 ÷ 2

Perimeter = 28.26

Graph the line that passes through the given point and has the given slope m!

Veseljchak [2.6K]

Answer:

The line would be y = -1/4x + 27/4

Step-by-step explanation:

In order to find this, we first need to note that the original slope is -1/4. And since parallel lines have the same slope, we know our new line will have that same slope. Now, we can use that slope and the point in point-slope form and solve for y.

y - y1 = m(x - x1)

y - 6 = -1/4(x - 3)

y - 6 = -1/4x + 3/4

y = -1/4x + 27/4

George has 36 cupcakes he has eight friends coming over to the party if he shares the cupcakes evenly with himself and all the g

Bogdan [553]

Answer:

Each person would get 4 cup cakes if all 8 friends attend the party.

Each person would get 12 cup cakes when 6 friends not attended the party.

Step-by-step explanation:

Given:

Total Number of cup cakes = 36

Number of friends coming to party = 8

Total number of people cakes need to distributed including George = 9

We need to find the number of cup cakes each person would get;

Solution:

Now we can say that;

number of cup cakes each person would get is equal to Total Number of cup cakes divided by Total number of people cakes need to distributed including George.

framing in equation form we get;

number of cup cakes each person would get = $\frac{36}{9}=4$

Hence Each person would get 4 cup cakes if all 8 friends attend the party.

Now Given:

Number of friends not attended the party = 6

So we can say that;

Total number of people cakes need to distributed including George = 9 - 6 = 3

So we can say that;

number of cup cakes each person would get = $\frac{36}{3} =12$

Hence Each person would get 12 cup cakes when 6 friends not attended the party.

Principal: $2600 Rate: 3% Time: 3 years What is the interest made?

Marianna [84]

Answer:

$234

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3%/100 = 0.03 per year,

then, solving our equation

I = 2600 × 0.03 × 3 = 234

I = $ 234.00

The simple interest accumulated

on a principal of $ 2,600.00

at a rate of 3% per year

for 3 years is $ 234.00.
