The Greens want to put an addition on their house 18 months from now. They will need to save $10,620 in order to achieve this go

BARSIC [14]

The easiest of the two options to prove is option A.

To see whether or not option A. is true, we need to find out how much the Greens have been saving every month. We know that the Greens have saved $6120 in the last year, or twelve months. To find out how much they have been saving each month, we need to divide the amount they have saved by the number of months they have been saving.

$6120/12 months

This turns out to be $510 each month.

Now, to find out whether or not option 11
A. is true, we need to find out the amount of money that the Greens would save in eighteen months.

$510 * 18 = $9180

Now that we have the amount of money that the Greens would save over eighteen months, we need to see if an additional month of saving would let them reach $10,620.

$9180 + $510 = $9690

Now, we know that option A is not true because the Greens would not have enough money after only one extra month of saving. Because option A is not true, option B must be true.

Which of the following options have the same value as %5, percent of 35? Choose 2 answers: (Choice A) A 5*35 (Choice B) B 5/100*

nasty-shy [4]

Answer:

B and D

Step-by-step explanation:

5% of 35 can be represented as 5% $\cdot35$ .

To find equations that make this work, we need to find different ways to represent 5%.

5% can be represented as fraction - over 100. The percentage over 100 will be equal to the percent.

So, $\frac{5}{100}$ . Multiplying by 35 gets us $\frac{5}{100}\cdot35$

This means that Choice B is correct.

Another way to represent 5% is as a decimal.

We already know that the fraction form of 5% is $\frac{5}{100}$ . This means that in the decimal, the number 5 will be two place values to the right of the decimal place.

0.<u>0</u><u>5</u>

So the decimal expansion of 5% is 0.05. Multiplyin by 35 get us $0.05\cdot35$ , so choice D works too.

Hope this helped!

Circle L is shown. Line segments K L and M L are radii. The length of K L is 12. Angle M L K is 60 degrees. Sector M L K with a

sergejj [24]

Answer:

$120\pi$ square units

Step-by-step explanation:

We are given that

Radius of circle=12 units

Angle MLK=60 degree

We have to find the area of sector that is not shaded.

Area of shaded sector MLK= $\frac{\theta}{360}\times \pi r^2$

Area of shaded sector MLK= $\frac{60}{360}\times \pi(12)^2=$ 24 square units

Area of whole circle= $\pi r^2=\pi (12)^2=144\pi$ square units

Area of sector that is not shaded =Area of whole circle-Area of shaded sector MLK= $144\pi-24\pi$

Area of sector that is not shaded= $120\pi$ square units
