L=2W+3, A=LW, using L from the first in the second gives you:
A=(2W+3)W
A=2W^2+3W, and we are told A=90 so
2W^2+3W=90
2W^2+3W-90=0
2W^2-12W+15W-90=0
2W(W-6)+15(W-6)=0
(2W+15)(W-6)=0, since W>0 for all real possibilities,
W=6ft, and since L=2W+3
L=15ft
So the pool will be 6 ft wide by 15 ft long.
Total number of loaves sold = 9360 + 2640 = 12000
Number of loaves of whole wheat bread = 2640
Percentage of loaves of whole wheat sold = 2640/12000 x 100 = 22%
Answer: 22%
Answer:
It would be 9,738.54
Step-by-step explanation: For starters, V= r^2(3.14)h
Make things easier by changing 20 1/2 to 20.5)) and 1 1/2 to 1.2))
Now multiply them to get your diameter. 20.5 * 1.20= 24.6.
You now have a diameter of 24.6. Now, divide 24.6 by 2 to get your radius. So, now you have a radius of 12.3. All you have to do now is plug in your numbers.
V= r^2(3.14)h V= (12.3)^2 (3.14) 20.5
you should get 9738.5373, but rounding by the hundredths place gets you 9738.54
Do well on your tests guys!
Knowing that an optimal shape is a cube is critical to solving this problem. With you now having that in mind, each side of the cube has a length of 4 inches. So the area of 1 face is 16 square units and the total surface area is 96 square units.
C because the coloured in dot means including -2 and above.
