Answer: Choice C) Inverse

Specifically this is the additive inverse. Note how each element adds to its corresponding pair to add to zero (eg: -6+6 = 0 in row1, column1). The additive inverse of x is the number -x. So x+(-x) = 0.

PLZ HELP ME IDK WUT IT IS!

Simora [160]

Answer:

1. c. 628 cubic cm

2. c. 502 cubic inches

Step-by-step explanation:

$V=\pi r^{2} h\\$

1.) 3.14 x 5^2 x 8

3.14 x 25 x 8 = 628

2.) 3.14 x ( 8/2 )^2 x 10

3.14 x 4^2 x 10

3.14 x 16 x 10 = 502.4

Roughly estimate the volume of a tennis ball in cubic cm by using 6 cm for diameter and 3 for pi. round the answer to the neares

galben [10]

The volume of ball is 113.04 cubic centimeter

Solution:

Given that we have to find the volume of tennis ball

Since the ball is of sphere shape, we can use the sphere formula

The volume of sphere is given by formula:

$V = \frac{4}{3} \times \pi \times r^3$

Where, "V" is the volume and "r" is the radius

Given that,

Diameter = 6 cm

Therefore,

$Radius = \frac{diameter}{2}\\\\Radius = \frac{6}{2}=3$

Substituting in formula, we get

$V = \frac{4}{3} \times 3.14 \times 3^3\\\\V = 4 \times 3.14 \times 3^2\\\\V = 12.56 \times 9\\\\V = 113.04$

Thus volume of ball is 113.04 cubic centimeter

Factoring GCF ab^2+20ab

aleksandr82 [10.1K]

Answer:

ab(ab + 20)

Step-by-step explanation:

Because we see both terms have at least one ab in it, we can factor out ab and get ab(ab + 20). However, because ab^2 does not have any coefficient, there is nothing more to factor out. Thus, ab is your greatest common factor, or GCF.
