Answer:

Volume: 366.6

Surface Area: 314.2

Explanation (look at below)

Step-by-step explanation:

Volume:

The radius of this sphere is 5 (half of 10). The equation will be \frac{4}{3} \pi5^3

When you calculate that, it will become: 366.6<-- rounded to the nearest tenth.

Surface Area:

4\pi5^2

=100Π

=314.2<-- rounded to the nearest tenth.

Add the following polynomials, t<br> - 3x2 - 2xy + y2<br> - 4x2 - xy +6y2<br> x2+ 6xy- y2
qaws [65]

Well, it is 3 polynomials so let’s break it down first.

(-3x*2 -2xy +y*2) (-4x*2 -xy + 6y*2)

Let’s add these first. The rule is to drop parentheses and add regularly. Bases stay the same, powers add and coefficients multiply.

Ans: (-7x*4 -3x*2 y*2 + 7y*4)

Now let’s add it with the last one.

The answer is: -6x*6 +3x*3 y*3 -6y*6

Can you use the SSS Postulate to prove QPS≈QRS?
Assoli18 [71]

Answer:

by SAS only

Step-by-step explanation:

based on the diagram we only have one side and one angle explicitly identified as equivalent.

but we have an implicit confirmation of the second side QS to the enclosed angle, because the triangles are presented that this side is the same for both triangles.

so, SAS applies (but no other, as we don't have any information on the 3rd side).

1) Miguel sells a house for $275,000. His commission for the sale is $6,875. What percent commission did he earn? (Make sure to
natulia [17]

Answer: 2.5%

Step-by-step explanation:

Let's use the rule of 3 here.

If the total price is $275,000 or 100% of the sale, then $6,875 is X% of the total sale.

Let's put money on one side and percentages on the other.

\frac{275000}{6875}=\frac{100}{x}

Solve for x;

x=\frac{6875*100}{275000}

x=2.5
