See Below.

Step-by-step explanation:

We are given that ∠1 and ∠7 are supplementary.

And we would like to prove that a is parallel to b.

Statements: Reasons:

$\textbf{\textsf{1. $\angle 1$ and $\angle 7$ are supplementary}}$ Given

$\textsf{2. $m\angle3$ + $m\angle 7$ $= 180$}$ Supplementary Angles

$\textsf{3. $\angle3$ and $\angle7$ are supplementary}$ Definition of Supplementary

$\textsf{4. }\bf{\angle 1 \cong \angle3}$ Congruent Supplements Theorem

$\textsf{5. }a\parallel b$ Corresponding Angles Converse

And we are done!

Describe the relationship between the area of a circle and its circumstances

valentina_108 [34]

Answer:

$A = \frac{r}{2}C$

Step-by-step explanation:

Given

Shape: Circle

Required

The area and the circumference (relationship)

This implies that, we write an expression that relates the area and the circumference.

Circumference is calculated as:

$C = 2\pi r$

Area is calculated as:

$A = \pi r^2$

The area can be rewritten as:

$A = \frac{2\pi r^2}{2}$

Further rewrite as:

$A = \frac{r}{2}*2\pi r$

Recall that: $C = 2\pi r$

So, the expression becomes

$A = \frac{r}{2}*C$

$A = \frac{r}{2}C$

Order these numbers from least to greatest. 11 , 3.30 , 175 , −10

timurjin [86]

If you would like to order the following numbers from least to greatest, you can do this using the following steps:

11, 3.30, 175, - 10
- 10 < 3.30 < 11 < 175

The correct result would be - 10 < 3.30 < 11 < 175.

I have 7200 bags of snickers. If the rest is Hershey’s and Twix is 2/3 of snickers, how many Hershey’s are there?

AveGali [126]

Answer:

Step-by-step explanation:

You have 7,200 bags of snickers

Twix is 2/3 that of snickers

Hershey's is ?

First you need to find out how much Twix you have.

You will need to multiply as a fraction: 2/3*7,200/1 (2 over 3 multiplied by 7,200 over 1)

Next multiply the two numerators together (numerators are the numbers on top of a fraction and the numbers on the bottom of the fraction are called denominators)

2 * 7,200 = 14,400

Next multiply the denominators together:

3 * 1 = 3

So now your fraction is 14,400/3 (14,400 over 3)

Now divide the denominator into the numerator:

14,400 divided by 3 = 4,800

So 2/3 of the 7,200 bags of Snickers equals 4,800 Twix

Now take away the Twix from the Snickers

7,200 - 4,800 = 2,400

So now all up you have:

7,200 bags of snickers

4,800 bags of Twix

2,400 bags of hershey's
