Answer:

r + 1

Step-by-step explanation:

Combine like terms. Add the constants together and add the terms with the variable r together. In order to add fractions, keep the common denominator and add only the numerators together. Then, simplify, and divide the numerator by the denominator if the result is a whole number.

This gives the following answer:

\frac{1}{3} r+\frac{1}{4} +\frac{2}{3} r+\frac{3}{4} \\=\frac{1}{3} r+\frac{2}{3} r+\frac{1}{4} +\frac{3}{4}\\=\frac{3}{3} r+\frac{4}{4} \\=r+1

Circle O is shown. Line segments B O and O C are radii. Point A is on the circle and is not within angle B O C.

The ratio of major to minor arc = 2 : 1

What is a Circle?

A circle is the locus of a point such that its distance from a fixed point (center) is always constant.

Calculation

The length of an arc (L) with center angle θ is given by:

                                          L = (θ/360) * 2πr

where r is the radius.

Putting the values in the above formula.

For the major arc:

L = (240/360) * 2πr

For the major arc:

l = ((360-240)/360) * 2πr

l = (120/360) * 2πr

The ratio of major to minor arc = [(240/360) * 2πr] / [(120/360) *2πr] = 2 : 1

The ratio of major to minor arc = 2 : 1.

Quinn has 6 bottles of water that each weigh \large \frac{3}{5} pound. What is the total weight of the water bottles?_
Art [367]

Answer:

3.6 pounds

Step-by-step explanation:

If 1 bottle weighs 3/5 pounds

the 6 bottles will weigh 6 x 3/5

= 18/5

ratio method :

1:3/5

6:x

since the ratios are direct we can cross multiply

18/5 = 1x

so the 6 bottles weigh 18/5 pounds or 3.6 pounds
