Answer:

M = 4.33885225095

Step-by-step explanation:

Area of the square ABFE = 10² = 100

M = 100 - (2P + Q)

Let’s calculate 2P + Q :

The area 2P + Q = area ΔABC + area of sector ACE + area of sector BCF

Note :

ΔABC is an equilateral triangle

m∠CBF = m∠CAE = 30°

area ΔABC  = (CG × AB)÷2 = (8.660254037844×10)÷2 = 43.30127018922

CG = √(10^2 - 5^2)=8.660254037844  (Pythagorean theorem)

area of sector BCF = area ΔACE = 100π ÷ 12 = (8.333333333333)π

then

Area 2P + Q = area  ΔABC + area sector ACE + area sector BCF

                      = 43.30127018922+(100÷12)π+(100÷12)π

                      = 43.30127018922+ (8.333333333333)π + (8.333333333333)π

                      = 95.66114774905

Conclusion:

M = 100 - (2P + Q) = 100-95.66114774905 = 4.33885225095

Answer:

Step-by-step explanation:

<u>Expression on the board :</u>

12.2x + 50.6 y + 3(1.4x - 2.6y)\\\\= 12.2x + 50.6y + 4.2x - 7.8y\\\\= 16.4x + 42.8y

<u>Expression by the student </u>:

<em><u> Expression 1 </u></em>:

4 ( 4.1x + 10.7 y ) \\\\=  ( 4 \times 4.1x ) + ( 4 \times 10.7 y)\\\\= 16.4x + 42.8y\\\\

The expression 1 is equivalent to the expression on the board. Because the coefficients of x and y are same on both.

<em><u>Expression 2 :</u></em>

<em><u /></em>2 ( 6.1x + 25.3 y + 2.1x -3.9y)\\\\= 2 ( 8.2x + 21.4y)\\\\=( 2 \times 8.2x ) + (2 \times 21.4y)\\\\= 16.4x + 42.8y<em><u /></em>

The expression 2 is also equivalent to the expression on the board. Because the coefficients of x and y are the same.

Shrek and Donkey are making parfait for an upcoming party.
Goryan [66]

Answer:

Step-by-step explanation:

They'd only make four from what the example shows; (0.01*2)*2=4

I can see where I might go wrong if Donkey was making the parfaits faster than Shrek?

I don't see what it's trying to get you to do, showing minimal info about it. If you're supposed to see either how fast Shrek can make within an hour, how much time they spent on the 5 parfaits-
