Hey so theirs this thing it gets you a person and all you have to do is take a pic of your problem and they will help you thank me later :)
Answer:
63
Step-by-step explanation:
Because, 100% of 70 would be 7. Now we have that number lets multiply it by 9 because of 90%. 9 x 7 = 63 first-graders
Answer:
38.13 ft squared
Step-by-step explanation:
Since it is half of a circle we first find the area of a normal circle then divide by two.
So to find the area of a circle it is pi times radius squared which in this case it would be 3.14 times 9 = 28.26
Then since it is a half circle we divide by two so
28.26/2 = 14.13
Then to find the area of the triangle we do 4 times 6 which is 24.
now we add the two which is 14.13 + 24 which is
38.13
Answer:
6
Step-by-step explanation:
Find the area of both triangles inside the bigger triangle and add them together.
Use the Pythagorean theorem to find the missing length of the leg in the smallest triangle:
a² + b² = c²
2² + b² = 3²
4 + b² = 9
5 = b²
2.2 ≈ b
Calculate the area of the smaller triangle:
1/2(bxh)
1/2(2 x 2.2)
1/2(4.4)
2.2
Calculate the area of the bigger triangle:
<em>We know that the longer leg is 3.8 units because we were able to subtract the length of the smaller triangle's leg from 6.
</em>
1/2(bxh)
1/2(2 x 3.8)
1/2(7.6)
3.8
Add both areas to find the area of the largest triangle:
3.8 + 2.2 = 6
