Answer:

Step-by-step explanation:

7 squared + 10 squared = 149

13 squared = 169

As you can see these two products are not equal. They have to be equal to be a right triangle.

So this triangle is not a right triangle.

Hope that helped you and have a great day!

Answer:

No it is not.

Step-by-step explanation:

Let h = 13, p = 10 and b =7

Using pythagoras theorem,

h² = p² + b²

13² = 10² + 7²

169 = 100 + 49

169 = 149

This is false so the triangle is not a right angled triangle.

A) 11c - 2d = -2
B) c + 8d = 8
B) c = 8 - 8d then substitute this into A)

A) 88 -88d - 2d = -2
A) 90 = 90d
d = 1
c = 0

A sphere has a volume of V=900 in cubed. What is the surface area?

ycow [4]

First, we must solve for the radius of the sphere:
V= $\frac{4}{3}$ $\pi$ $r^{3}$
r=(3 $\frac{V}{4 \pi }$ ) $^{ \frac{1}{3} }$
r=(3* $\frac{900}{4 \pi }$ ) $^{ \frac{1}{3} }$
r≈5.99

Second, we must solve for surface area:
A=4 $\pi$ $r^{2}$
A=4* $\pi$ * $5.99^{2}$
A≈450.88 $in^{2}$
