Answer:

$4 \sqrt{2}$

Step-by-step explanation:

Rewrite 32 as the product of 16 and 2:

$\implies \sqrt{32}=\sqrt{16 \cdot 2$

Apply exponent rule $\sqrt{a \cdot b}=\sqrt{a}\sqrt{b}$

$\implies \sqrt{16 \cdot 2}=\sqrt{16}\sqrt{2}$

Rewrite 16 as 4²:

$\implies \sqrt{16}\sqrt{2}=\sqrt{4^2}\sqrt{2}$

Apply exponent rule $\sqrt{a^2}=a$

$\implies \sqrt{4^2}\sqrt{2}=4 \sqrt{2}$

How to find y in angle sum theorem

Svetach [21]

Answer:

y = 90°

Step-by-step explanation:

110° is the measure of exterior angle of bigger triangle.

-> (x + x) + 70° = 110° (By exterior angle theorem)

-> 2x = 110° - 70°

-> 2x = 40°

-> x = 40°/2

-> x = 20°

y is the measure of exterior angle of smaller triangle.

-> y = x + 70° (By exterior angle theorem)

-> y = 20° + 70°

-> y = 90°

Answer:

a = 6

Step-by-step explanation:

-6(2 + a) = -48

it is basically 2 steps

Divide by -6 first

(2 + a) = -48 / -6

2 + a = 8

Suppose you have 3 quizzes and want an average of 7 points. List at least five ways this average can be accomplished. keep in mi

Sunny_sXe [5.5K]

Answer:

4,9,8 = 4+9+8 = 21

9,9,3 = 9+9+3 = 21

6,7,8 = 6+7+8 = 21

8,8,5 = 8+8+5 = 21

5,7,9 = 5+7+9 = 21

Step-by-step explanation:

The question says you get 7 points per quiz out of 3 quizzes.

7+7+7 = 21

Now that we know that we need a total score of 21, we therefore need to distribute it among the three quizzes.

Remember;

None of these scores are to be higher than 10. We need to add up scores below 10.

4,9,8 = 4+9+8 = 21

9,9,3 = 9+9+3 = 21

6,7,8 = 6+7+8 = 21

8,8,5 = 8+8+5 = 21

5,7,9 = 5+7+9 = 21

All of these gives 7 as average.

Somebody please help me with this math question and I’ll give you 26 points please if you are going to submit links do not answe

vampirchik [111]

Answer:

$600

Step-by-step explanation:

Simple Interest Rate: A = P(1 + RT)

A $\longmapsto$ Total Value

P $\longmapsto$ Principle

R $\longmapsto$ Rate

T $\longmapsto$ Time

__________________________________________________________

<h2>Step 1: Insert Values </h2><h2> </h2>

Let's plug the info we have into the formula:

A = 4000(1 + 0.05(3))

A = 4000 + 4000(0.15)

A = 4000 + 600

A = 4600

__________________________________________________________

<h2>Step 2: Finding the Interest</h2><h2 />

So the total value she ends up with $4600, but we want to find the extra value, or interest, she has to pay.

To find this we subtract the principle from the new value:

4600 - 4000 = 600

Liz has to pay $600.
