Since h and 2 together is a sum, and sum is what you get when you add two or more number/variables, add h and 2 for the expression h+2.
Since 12 is being divided by (h + 2), put the 12 above the h+2. This gives you the following expression:
\frac{12}{h+2}

Scott has $500 in the bank. He withdraws the same amount of money each week for 12 weeks, at which point he has $20 left in the
Gre4nikov [31]
Scott knew that the only chance we would have to answer this problem would be if he kept his money in a bank that pays no interest, so that's what he did.  The bank simply stored his money in a mayonnaise jar under a tightly-guarded mattress, and he was allowed to come in and take some out of it each week.

He started with $500. He withdrew (500 - 20) = $480 in 12 weeks.

So he must have come in and picked up 480/12 = $40 each week.

The area of a circle, in terms of π, is 80π m2. Find the value of the radius. Give your answer as a simplified surd.
jolli1 [7]

Answer:

r=4\sqrt{5}\:\: \sf m

Step-by-step explanation:

\textsf{Area of a circle}=\pi r^2 \quad \textsf{(where r is the radius)}

Given:

  • Area = 80π m²

Substitute the given value into the formula and solve for r:

\implies 80 \pi = \pi r^2

\implies \dfrac{80 \pi}{\pi} = \dfrac{\pi r^2}{\pi}

\implies 80=r^2

\implies \sqrt{r^2}=\sqrt{80}

\implies r=\sqrt{80}

\implies r=\sqrt{16 \cdot 5}

\implies r=\sqrt{16}\sqrt{5}

\implies r=\sqrt{4^2}\sqrt{5}

\implies r=4\sqrt{5}

What would D,E, I need help with these questions
Ilia_Sergeevich [38]

Answer:

D - 43°

E - 43°

Step-by-step explanation:

In squares all sides are equal, which means one of these angles are given and neither one leave the square, so 43° would be the degree of each angle inside this square.

For each of the following, select the correct words from the word bank to complete each statement.
Anuta_ua [19.1K]

Answer:

Angles opposite one another that share a vertex are called <u>vertical</u> angles.

When one of these angles undergo a rigid transformation so that it fits exactly over the other, we know that the two angles are <u>congruent</u>

When two parallel lines are crossed by another line called the <u>transversal</u> the angles created inside the parallel lines but on opposite sides of the crossing lines are called <u>alternate</u> <u>interior</u> angles. Angles of this type have the same measurement as one another. Two figures are <u>similar</u> if one can fit exactly over the other after rigid transformations and dilations

Step-by-step explanation:

Vertically opposite angles are always equal (congruent)

The transversal line is the line that crosses two or more parallel lines

Alternate interior angles formed by two parallel lines crossed by a common transversal, are congruent

Two plane geometric figures are similar if they their corresponding interior angles are congruent
