Answer:

5/9

Step-by-step explanation:

find the common divisor for both the numerator and denominator.

25 and 45 could be divided by 5, so divide both by 5

$\frac{25}{45}$ ÷ $\frac{5}{5}$ = $\frac{5}{9}$

A recipe calls for a total of 3 2/3 cup flour and sugar.if the recipe calls for 1/4 cups of sugar,how much flour does he need

viva [34]

You'll want to convert 3 2/3 into a common denominator with 1/4.
The nearest common denominator of 3 and 4 is 12.
1/4 * 3/3 = 3/12
2/3 * 4/4 = 8/12
You need 3 and 8/12 in total so subtract 3/12 from 3 8/12 to get the flour
3 8/12 - 3/12 = 3 5/12.
You would need 3 5/12 cups of flour.

For a circle with a radius of 6 feet, what is the measurement of the central angle (in degrees) that intercepts an arc

geniusboy [140]

Answer: The central angle measures 135 degrees

Step-by-step explanation: We have been given an arc with length 9pi/2 feet and a radius of 6 feet. The arc is shown in the attached diagram (please see attachment). The central angle subtended by this arc is at point O and has been labeled angle X.

So if the diagram shows arc AB with length 9pi/2 and radius AO with length 6, we can use the formula to compute “Length of an arc” to arrive at the missing angle.

Length of an arc = X/360 x 2pi x radius

Substituting for the known values, our formula can now be re-written as

9pi/2 = X/360 x 2pi x6

By cross multiplication we now have

9pi/2pi x 6 = 2X/360

We simplify as much as possible by dividing all like terms, hence pi divides pi on the left side of the equation. Also 2 divides 360 on the right side of the equation.We now arrive at,

9/12 = X/180

Simplify even further and we have

3/4 = X/180

By cross multiplication we now have

(3 x 180)/4 = X

540/4 = X

135 = X

Therefore the central angle that intercepts the arc measures 135 degrees.

FIFO does not assume which of the following? sell old inventory first.or sell the new inventory first

pentagon [3]

First In First Out.

FIFO intends to sell the first one that comes through the door first, and that item will be the oldest one in the inventory, so the old one gets sold first.

so it doesn't assume to sell the new one first.
