Find the measure of each marked angle.

Answer:

P = 2(5w) + 2 (5L)

Step-by-step explanation:

To write this in standard form we need to multiply the two terms in parenthesis on the right side of the equation.

To multiply these two terms you multiply each individual term in the left parenthesis by each individual term in the right parenthesis.

y

=

−

3

(

x

−

7

)

(

x

+

4

)

becomes:

y

=

−

(

(

+

(

−

(

)

y

=

−

(

x

x

x

)

We can now combine like terms:

y

x

y

We can now multiply each term in parenthesis by

After dilate the figure by a scale factor of 2.5, the orientation of the figure is not change.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The figure is dilated by a a scale factor of 2.5.

Now, We know that;

After dilation we get the pre image of the image which orientation of the figure is not change and both are similar to each other.

Thus, After dilate the figure by a scale factor of 2.5, the orientation of the figure is not change.

Answer:

9/25

Step-by-step explanation:

In this case, 0.36 has two numbers after the decimal, so, we place 100 in the denominator and remove the decimal point.

⇒ 36/100

After reducing this fraction we get

⇒ (36 ÷ 4) / (100 ÷ 4) = 9/25

Answer:

I'm guessing frequency means deposits,

a. 13

b. $50

c. not sure what this means (sorry!)

d. $2,535

Step-by-step explanation:

Can I have brainliest? It would help me out, if not thanks anyways! Hope this helped and have a nice day!

Part A

-------------

Explanation:

Add up all the values in the frequency column. This is because everything in the table represents a deposit of some kind.

3+1+5+2+2 = 13

========================================================

Part B

-------------

Explanation:

Simply list the value that has the highest frequency. This is the mode. It's possible to have more than one mode, and it's also possible to not have any mode at all.

========================================================

Part C

-------------

Explanation:

Let's list out all of the deposits. The repeats aren't typos. The deposits are

125, 125, 125, 300, 50, 50, 50, 50, 50, 205, 205, 100, 100

They sort to

50, 50, 50, 50, 50, 100, 100, 125, 125, 125, 205, 205, 300

Since we have n = 13 items here, the halfway point is n/2 = 13/2 = 6.5 which rounds to 7. The median is in slot 7. We have 6 items below the median and 6 items above the median (giving 6+1+6 = 13 total).

The value in slot 7 is 100, which shows us that 100 is the median.

========================================================

Part D

-------------

Explanation:

Form a third column of values where we multiply each deposit by the corresponding frequency. Check out the table below.

After this third column is formed, add up those values to get the total amount of deposits. Spreadsheet software can make quick work of something like this. I used OpenOffice spreadsheet which is free software.

You should find that 1535 is the total amount deposited. This value is then added onto the $1000 already in there to get 1000+1535 = 2535

Answer:

Of course the percentage is an increase. If it moves from 50ft to 190 ft its an increase. So you can automatically cross out “c” and “d”.

Now just think about it logically. This can save you from a lot of work.

So you have it from 50ft to 190 ft.

Use 100% place holders.

50ft*100 percent is 50

50ft*200 percent is 150

Now your somewhere close near the 190 ft range.

THink about the last two options, you can ignore the 200 percent since thats what we used as the closest possible place holder.

Now use 50% place holders.

50% of 50 is 25.

so 175 is the closest we can get with 250%

Now we still have about a 15 ft space.

250% is obviously greater then 238% so we can elimate that option.

The final answer is (B)

Step-by-step explanation:

If wanted proof

So we discussed this logically but if you want it mathematically below is the explanation:

50ft to 190 ft.

To calculate percentage of change you want to first find the distance.

190-50=140

Theres a 140 ft change.

Now you can use proportions

50/1 = 140/x

The 50/1 represents 50 feet for 100 percent or 1

The 140 represents 140 feet for (x) feet since its unknown

now cross multiply

50*x

140*1

50x=140

Now solve

140/50=2.8

2.8 is the deciaml If you convert it to a percentage you just multiply it by a hundred since percent means out of a hundred.

2.8 out of a hundred it 280%

Answer:

divide both sides by 6

Step-by-step explanation:

3(2x + 10) = 54 ( distribute the parenthesis by 3 )

6x + 30 = 54 ( subtract 30 from both sides )

6x = 24

The last step is to divide both sides by 6

x = 4
