Well, let's first find our rate of bags to meters.
If 12 bags of plaster covers 54m^2, then we need to divide 54 by 12 to figure out how many meters 1 bag of plaster covers. We will then use that rate and divide 36 by it in order to solve for how many bags of plaster is required.
54 / 12 = 4.5.
This means each bag of plaster covers 4.5m^2.
Divide 36 by 4.5;
36 / 4.5 = 8.
This means that we will need 8 bags of plaster to cover 36m^2.
I hope this helps!
Let x = number of tbsp of pure maple syrup 1.00x = maple syrup content of pure syrup0.45(48) = maple syrup content of 45% solution0.60(x+48) = maple syrup content of mixtureThen, 1.00x + 0.45(48) = 0.60(x+48)
x + 21.6 = 0.60x + 28.80.40x = 7.2x = 18 tbsp
Answer:
0.825
Step-by-step explanation:
In order to make the denominator 100, we must multiply both the numerator and denominator by 2.5
33*2.5 = 66 + 16.5 = 82.5
33/40 = 82.5/100
Now we solve, 82.5/100 = 0.825
A trapezoid will always have the maximum area for a given perimeter of a quadrilateral.
X + y = 24....multiply by -3
3x + 5y = 100
---------------
-3x - 3y = - 72 (result of multiplying by -3)
3x + 5y = 100
----------------add
2y = 28
y = 28/2
y = 14 <== 5 pointers
x + y = 24
x + 14 = 24
x = 24 - 14
x = 10 <== 3 pointers
