Answer:

7/9

Step-by-step explanation:

First Fractions need to be same so bottom number is 9

So to get 1/3 to nine we need to do 3x3 which equals 9

So we are with 3/9 and 4/9. Add top numbers and u get 7/9

7/9 because you have to have a equal denominator so you multiply 3x3=9. then u do 1x3=3 so it’s 3/9 + 4/9 which is really 7. so mikey ran 7/9

Answer: $1 \frac{3}{16}\ lb$

Step-by-step explanation:

You know that Sara has 8 ounces of vanilla yogurt in her cup and her father’s yogurt weighs 11 ounces. Then, the total ounces of frozen yogurt they buy altogether is:

$total_{(ounces)}=8\ oz+11\ oz\\\\total_{(ounces)}=19\ oz$

The next step is to make the conversion from ounces to pounds.

You need to remember that:

$1\ lb=16\ oz$

Therefore:

$total_{(pounds)}=(19\ oz)(\frac{1\ lb}{16\ oz})=\frac{19}{16}\ lb$

This result expressed as a mixed number, is:

$total_{(pounds)}=1\frac{3}{16}\ lb$

Anettt [7]

Answer:

395.85

Step-by-step explanation:

If the diameter is 12, then the radius must be 6. Following the formula of pi: 2 * pi * radius, our result is 37.7. 37.7 * 10.50 is 395.85

I really hope this helps. My memory of circles and pi isn't the best.

A farmer has 500 acres to plant acres of corn, x, and acres of cotton, y. Corn costs $215 per acre to produce, and cotton costs

hodyreva [135]

Answer:

x + y = 500

215x + 615y = 187,500

Step-by-step explanation:

The first equation can show the amount of land. The farmer has 500 acres to plant corn, x, and cotton, y.

x + y = 500

The second equation can show the cost. The farmer has $187,500 to invest when corn costs $215 per acre and cotton costs $615 per acre.

215x + 615y = 187,500

The system of equations is

x + y = 500

215x + 615y = 187,500

Martin is covering his bathroom floor with square tiles. When he gets to the end of a row of tiles, he needs to cut the length o

kati45 [8]

All squares are equal sides.Let X be the side of a square. $\\$ Area of square,A = x^2

Here a tile is a square of side length 'x'. The following polynomial represents,

(x - 4) represents "the width of the new tile" (because 4 inches cut from the tile)

4x represents "the area removed from the tile" (since one side of removed tile is 'x' and other is 4 inches.)

x2 represents "area of original tile" of side equal to 'x'

x represents "the length of the new tile" (since length of new tile is not reduced. Length =x and breadth is x-4
