Answer:
156 ft^3
Step-by-step explanation:
1) find the volume of the parallelepiped:
V = side^2 x height = 6^2 x 3 = 108 ft^3
2) find the base area of the pyramid:
base area = side^2 = 6^2 = 36 ft^2
3) find the volume of the pyramid:
V = (base area x height)/3 = (36 x 4)/3 = 48 ft^3
4) find the total volume
V = 108 + 48 = 156 ft^3
* means multiply, sqrt=radical
expand
-10+sqrt2*8i-sqrt2*15+24i
group
(-10-sqrt2*15)+(sqrt2*8+24)i
not exactly sure though
Answer:
56.25%
Step-by-step explanation:
800 - 350 = 450
1% of 800 = 8 (800 divided by 100)
450 divided by 8 = 56.25
Answer:
4/125
Step-by-step explanation:
<em>Answer:</em>
<em>38%</em>
<em>Step-by-step explanation:</em>
<em>60 percent girls</em>
<em>50 percent of girls walk</em>
<em>50 percent take the bus</em>
<em></em>
<em>40 percent boys</em>
<em>20 percent walk</em>
<em>80 percent take the bus</em>
<em></em>
<em>If there are 100 people in the school</em>
<em>60 girls</em>
<em>30 girls take the bus</em>
<em></em>
<em>40 boys</em>
<em>8 boys walk</em>
<em></em>
<em>8+30=38</em>
<em>38% of the people walk to school</em>
