Marie has a recipe that calls for 2 cups of flour for 3 dozen cookies. How much flour would she

1 answer:

3 0

So since we know that 2 cups of flour gives us 3 dozens (36 cookies), we can divide both by 2 to see how much 1 cup of flour gives us. That would give us 1.5 dozens (18 cookies) for 1 cup of flour. So 3 cups of flour would make 54 cookies. Then we can divide 1 cup of flour by 3 to see how much 1/3 cup of flour would give us. 1/3 cup makes 6 cookies so 3 1/3 makes 60 cookies.

All you gotta do is add up the two sides and then subtract it from 47.3 .
So 10+17.3= 27.3
47.3-27.3= 20

2 Nine identical circles are cut from a square sheet of paper whose sides are

Ivanshal [37]

Answer:

278.64cm²

Step-by-step explanation:

Area of the sheet left out = Area of the square - Area of the 9 circles

Area of the square = L^2

L is the side length of the square

A = 36^2

Area of the square = 1296cm^2

Diameter of a circle = 38/3 = 12cm

Area of a circle = πr²

r is the radius = 12/2 = 6cm

Area of a circle = 3.14(6)²

Area of a circle = 3.14 * 36

Area of a circle = 113.04cm²

Area of 9 circles = 9 * 113.04

Area of 9 circles = 1,017.36cm²

Area of the left over = 1296 - 1,017.36

Area of the left over = 278.64cm²

Simplify.<br> 4/x^2-35 - 1/x+5

Oksana_A [137]

If I understand your question well, I suppose you mean $\frac{4}{ x^{2} -35} - \frac{1}{x+5}$
$\frac{4}{ x^{2} -35} - \frac{1}{x+5} = \frac{4}{(x+5)(x-7)}- \frac{1}{x+5} \\ = \frac{1}{x+5}( \frac{4}{x-7}-1) \\ = \frac{1}{x+5}( \frac{4}{x-7}- \frac{x-7}{x-7}) \\ = \frac{1}{x+5}( \frac{4-x+7}{x-7}) \\ = \frac{1}{x+5}( \frac{11-x}{x-7}) \\ = \frac{11-x}{ x^{2} -35}$
