Answer:

8 3/4 cups of flour

Step-by-step explanation:

So, we know that you need 5 pies and that each pie takes 1 3/4 cup. So basically all you have to do is come up with an equation, mine looks like

5 x 1 3/4 or 5 x 1.75 if you don't like fractions.

5 x 1 3/4 = 8 3/4

5 x 1.75 = 8.75

Answer:

BCE on edunuity

Step-by-step explanation:

Answer:

the answer is 20

Using proportions, it is found that the fraction of players who don't stretch that get injured is: [tex]\frac{5}{6}[/tex]

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

From the data given, there are 50 - 32 = 18 footballers who do not stretch regularly, and of those 19 - 4 = 15 stretched, hence the fraction of players who don't stretch that get injured is:

[tex]f = \frac{15}{18} = \frac{5}{6}[/tex]

Answer:

c is the right one

Step-by-step explanation:

Step-by-step explanation:

We know that,

sum of all angles in a triangle measures 180°

Then,

(2x+6)+(3x-25)+y= 180°

2x+3x+y=180-6+25

5x+y=199°

x+y=199/5

=39.8

Step-by-step explanation:

since all 4 sides are equal in length, the figure is a square.

let the length of the square be lm.

529 = l x l

l = 23m

perimeter = 23 x 4 = 92m

Answer:

Angle A = 97.5º

Step-by-step explanation:

Supplmentary means 2 angles that equal 180º. So we already have 1 angle, so now all we have to do is subtract 82.5 from 180.

180 - 82.5 = 97.5

Angle A and angle B are supplementary. Then the measure of the angle A will be 97.5°.

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360 °.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

Angle A and angle B are supplementary. The measure of angle B is 82.5°.

Then the equation is given as,

∠A + ∠B = 180°

Simplify the equation, then the measure of the angle A will be calculated as,

∠A + 82.5° = 180°

∠A = 180° - 82.5°

∠A = 97.5°

Angle A and angle B are supplementary. Then the measure of the angle A will be 97.5°.
