We can write this as a ratio: 11:27 or 11/27

A circle is a total of 360 degrees.

~Multiply

11/27 * 360/1

~Simplify

3,960/27

~Simplify

146 2/3

Best of Luck!

If a rectangle is altered by increasing its length by 20 percent and its width by 10 percent, its area increases by a percent. W
aleksklad [387]

Answer:

D

Step-by-step explanation:

Remember that the formula for the area of a rectangle is:

A=lw

Where l is the our length and w is our width.

If we increase our length by 20%, this means that we add 20% or 0.2 of our old length to our old length. So, our new length will be:

l_{new}=l+.2l

Combine like terms:

l_{new}=1.2l

Similarly, if we increase our width by 10%, this means that we add 10% or 0.1 of our old width to our old width. So, our new width is:

w_{new}=0.1w+w

Combine like terms:

w_{new}=1.1w

Therefore, our new area will be:

A_{new}=(l_{new})(w_{new})

Substitute 1.2l and 1.1w. This yields:

A_{new}=1.2l(1.1w)

Multiply:

A_{new}=1.32lw

Our old area is:

A_{old}=lw

So, our area increased by a factor of 1.32.

This is the same as 32% of our old area.

So, our answer is D.

And we're done!

Add the fraction 1/2+3/18
AURORKA [14]
1/2 + 3/18 = 9/18 + 3/18 = 12/18 = 2/3

3/45 + 6/50 = 1/15 + 3/25 = 5/75 + 9/75 = 14/75
