If you write down your information first it will be easier to visualise a method:

15 rolls of ribbon, each is $5\frac{3}{8}$ yards long. 10 wedding baskets. She takes $\frac{3}{4}$ yards away from every basket.

So, in mathematical terms:

$(15*5\frac{3}{8})-10(\frac{3}{4})\\\\(15*\frac{43}{8})-5(\frac{3}{2})\\\\(\frac{645}{8})-\frac{15}{2}\\\\\frac{645}{8}-\frac{60}{8}\\\\\frac{585}{8}\\\\585/8=73.125$

Your answer is $\frac{585}{8}$ or 73.125 yards.

Answer:

Step-by-step explanation:

Let's find the area of each of the two circles.

First Circle:

The first circle has a diameter of 10 inches. That means the radius is 5 inches. So, its area is:

$A=\pi r^2\\A=\pi (5)^2\\A=25\pi$

Second Circle:

The second circle has a diameter twice that of the first. So, the diameter is 20 inches. This means that the radius is 10 inches. Find the area:

$A=\pi r^2\\A=\pi (10)^2\\A=100\pi$

Now, find the ratio between them by dividing:

$\frac{\text{Smaller}}{\text{Larger}}=\frac{25\pi}{100\pi}$

Simplify:

$\frac{\text{Smaller}}{\text{Larger}}=\frac{1}{4}$

1/4 is the same as 1:4

So, our answer is C :)

Answer:

$29000 with a margin of error of $5000

Step-by-step explanation:

We have that the midpoint between the given values is

(X1+X2) / 2 = ($34000+$24000)/2 = $29000

We have that the midpoint between the given values would be

(X2-X1)/2=($34000-$24000)/2=$10000/2=$5000

So I can write that approach as $29000 with a margin of error of $5000

Done

Let $G$ denote the centroid of triangle $ABC$. If triangle $ABG$ is equilateral with side length 2, then determine the perimeter

belka [17]

Hey there!

You are trying to find the perimeter of triangle ABC. Each side is 2. Since there are 3 sides on a triangle, multiply 2 by 3 to get 6. You do not need the centroid for this problem.

I hope this helps!
