Answer:
228
Step-by-step explanation:
first we will find the area of the triangles on the sides of the prism.
(triangle area formula: (b*h)/2)
(6*5)/2 = 15
we multiply this by 2 since there are 2 sides that contain the same measures:
15*2 = 30
then we find the rectangles that are on the sides (not the base)
(rectangle formula: b*h)
11*6.5 = 71.5
multiply this by 2 since there are two sides:
71.5*2 = 143
finally we find the base using the same formula as we did to find the rectangles:
11*5 = 55
finally we add them all up:
30+143+55 = 228
hope this helps! :)
The value of the 8 is 800000
Answer:
first quartile is 14
Step-by-step explanation:
{13,15,19,25,35}
first quartile = (13+15)/2 = 14
second quartile = 19
third quartile = (25+35)/2 = 30
Probability is favorable outcome to total possibilities.
So, any probability will be x/80
There are 36 seventh graders, and 22 girls in eighth grade (40-18=22). 36+22=58
The probability of drawing either a seventh grader or a girl is 58/80, or 72.5%
Option B has more, if you want to have mathematical work just set each of the square side lengths to 1. In the first figure, you have 4 units square for each square so 2 units sq on the first and 4 on the second. Then since the other shapes are half circles or 1/4 circles we can put them together to get full and partial circles. The first shape had 2 full circles and the second shape has 1.5. SO using 1 as the radius, you get 3.14 units sq per circle. Leaving you with (<em>circles) </em>6.28 + <em>(squares)</em> 2 leaving you with 8.28 units sq for figure 1 and <em>(circles)</em> 4.71 + <em>(squares)</em> 4 leaving you with 8.71 for figure 2. This leaves you with a .43 difference. Hope this helps
