Answer:

D. 140°.

Step-by-step explanation:

We have been given an image of two intersecting lines. We are asked to find the measure of angle 3.

We know that when two line intersect they form two pairs of vertical angles.

Since angle 3 and angle 4 are vertical angle, they will be equal in measure. Using this information, we can set an equation as:

$m\angle 3=m\angle 4$

Upon substituting the expression for angle 3 and angle 4 is our equation we will get:

$x+30=2x-80$

$x-2x+30=2x-2x-80$

$-x+30=-80$

$-x=-110$

Upon dividing both sides of our equation by -1, we will get:

$\frac{-x}{-1}=\frac{-110}{-1}$

$x=110$

Upon substituting $x=110$ in expression for angle 3, we will get:

$m\angle 3=x+30$

$m\angle 3=110+30$

$m\angle 3=140$

Therefore, the measure of angle 3 is 140 degrees and option D is the correct choice.

The cell phone plan from Company C costs $10 per month, plus $15 per gigabyte for data used. The plan from Company D costs $80 p

DaniilM [7]

Answer:

C(g) = 10 + 15g

C'(g) = 80

The monthly charges of Company C for using 2 Gigabyte of data usage.

Step-by-step explanation:

The cell phone plan from Company C costs $10 per month, plus $15 per gigabyte for data used. The plan from Company D costs $80 per month, with unlimited data.

Now, the monthly cost in Company C for using g gigabyte of data will be

C(g) = 10 + 15g ........ (1)

Again, the monthly cost in Company D for using g gigabyte of data will be

C'(g) = 80 ......... (2)

Now, from equation (1), the statement C(2) = 10 + 15 × 2 = 40, means that monthly charges of Company C for using 2 Gigabyte of data usage.

10 times as many as 1 hundred is hundreds or thousand

Paladinen [302]

10 times as many as 1 hundred is 10 hundred or 1 thousand.

<h3>Further explanation</h3>

Consider the following sentence:

X times as many as Y refer to X multiplied by Y

Therefore, the phrase 10 times as many as 1 hundred is - can be rewritten to 10 multiplied by 100 is

We can say this is a simple multiplication operation, which is one of four basic operations, i.e.,

addition,
subtraction,
multiplication, and
division.

However, the case we face is only a multiplication, not accompanied by another operation.

Let's go back to our problem. We think naturally about this multiplication. 10 times 100 means there are two options like the following:

Addition of 10 as many as 100 times (there are 100 terms, this is too much written).
Addition of 100 as many as 10 times (there are 10 terms, still enough to be written).

Actually both are the same.

10 x 1 hundred = 100 + 100 + 100 + 100 + 100 + 100 + 100 + 100 + 100 + 100

We state it quickly.

10 times as many as 1 hundred thousand is

10 x 1 hundred = 1 thousand, or

$\boxed{ \ 10 \times 100 = 1,000 \ }$

Based on present sources, the proper questions are as follows:

10 times as many as 1 hundred is __? __ hundreds or __? __ thousand.

Therefore, we rewrite the results in the unit form as requested.

10 times as many as 1 hundred is 10 hundred or 1 thousand.

Note:

The commutative property of multiplication: $\boxed{a \times b = b \times a}$
