The ratio of girls to boys. There will be 18 girls
Pythagorean Therom
a^2 + b^2 = c^2
5^2 +b^2 = 7^2
25=b^2 = 49
49-25=b^2
49-25=14
b^2=24
b=sqrt24
sqrt24=4.89898
Answer:
The medians of a triangle intersect at a point called the
centroid of the triangle
Step-by-step explanation:
The median of a triangle is a segment joining any vertex to the midpoint of the opposite side. The medians of a triangle are concurrent (they intersect in one common point). The point of concurrency of the medians is called the centroid of the triangle.
Let's find the area of the base.
It's a rectangle that's 3.8 by 4.8, so let's multiply.
3.8×4.8=18.24
We have two different triangles.
Triangle one has a height of 2.6 and base of 4.8. But there are two of them.
2.6×4.8×0.5=6.24×2= 12.48; this is the area of two triangles.
Another set of triangles has a height of 2.9 and a base of 3.8.
2.9×3.8×0.5=5.51×2=11.02
Let's add all the areas together.
18.24+12.48+11.02
41.74
The surface area is 41.74 m², so the third option.
He sold 1,350 shares for $27,000
27,000÷1,350=20
So he sold each share for $20
He bought them for $12 and sold them for $20.
$20-$12=$8
He sold each share for $8 more than he bought them for, he made $8 of profit on each share.
