Put the value of x where x is and do the arithmetic.
-7·9 +6 = -63 +6 = -57
Answer:
7.06 x 10^(-7) ft 3
Step-by-step explanation:
We have the formula to calculate the volume of an octagonal Pyraamid as following:
<em>+) Volume of octagonal pyramid = 1/3 * Area of the base * Height</em>
As given, the base of the pyramid is an octagon with area equal to 15mm2
=> Area of the base = 15 mm2
The height of the pyramid is the length of the line segment which is perpendicular to the base - which is the red line.
=> Height = 4mm
So we have:
<em>Volume of octagonal pyramid = 1/3 * Area of the base * Height</em>
<em>= 1/3 * 15 * 4 = 20 mm3</em>
<em />
As: 1 mm3 = 3.53 x 10^(-8) ft 3
=> 20 mm3 = 7.06x10^(-7) ft 3
So the volume of the pyramid is : 7.06 x 10^(-7) ft 3
Answer:
4 boxes
Step-by-step explanation:
the greatest number that you can divide all these numbers by equally is 4. There will be 9 chocolate, 13 red velvet, and 12 vanilla cupcakes in each box.
Answer:
y = (2.5 + 0.4x) / (10 + x) × 100
Step-by-step explanation:
The total quantity of the trail mix = 10 lb
Dried fruit = 25% of the trail mix
=25% of 10 lb
= 0.25 × 10
= 2.5 lb
Employee adds x lb of Active Mix, which contains 40% dried fruit by weight.
Total trail mix after addition = ( 10 + x ) lb
Total dried fruit = 2.5 lb + 40% of x
= (2.5 + 0.4 * x) lb
= (2.5 + 0.4x) lb
Let
y = percent of dried fruit in the new type of trail mix.
% of dried fruit in the new type of trail mix = ( quantity of dried fruit in the trail mix / total quantity ) × 100
y = (2.5 + 0.4x) / (10 + x) × 100
Option C is the correct answer
