alekssr [168]

Answer:

The real distance is 260 miles

Step-by-step explanation:

From the question;

1.5 inches in map is 26 miles

Thus;

15 inches will be x miles

To get the value of x, we do a cross-multiplication

we have this as:

15 * 26 = 1.5 * x

x = (15 * 26)/1.5

x = 10 * 26 = 260 miles

The whole sales price for a chair is $165. A certain furniture store marks up the wholesalers price by 15%. Find the price of th
vichka [17]

Answer:

$189.75

Step-by-step explanation:

Whenever you want to find the percent of something, you need to turn the percent into a decimal. In this case, we need to find 115% of the wholesale price because there is a markup, so the cost will be higher.

115% as a decimal is 1.15. Here is how the equation will be set up:

$165 • 1.15 = $189.75

No rounding is necessary for this problem because it is already to the nearest cent.

Select 3 expressions that have a sum or difference of 3 /4 .
cupoosta [38]

Answer:

The Three expressions that have a sum or difference of 3 /4 .

B . 11/12 − 1/6

C. 3/5 + 3/20

E . 2/3 + 1/12

Step-by-step explanation:

The Three expressions that have a sum or difference of 3 /4 .

are

B . 11/12 − 1/6

\dfrac{11}{12}-\dfrac{1}{6}=\dfrac{11}{12}-\dfrac{1\times 2}{6\times 2}\\\\\dfrac{11}{12}-\dfrac{1}{6}=\dfrac{11}{12}-\dfrac{2}{12}=\dfrac{11-2}{12}=\dfrac{9}{12}=\dfrac{3}{4}

Therefore,

\dfrac{11}{12}-\dfrac{1}{6}=\dfrac{3}{4}

C. 3/5 + 3/20

\dfrac{3}{5}+\dfrac{3}{20}=\dfrac{3\times 4}{5\times 4}+\dfrac{3}{20}\\\\\dfrac{3}{5}+\dfrac{3}{20}=\dfrac{12}{20}+\dfrac{3}{20}=\dfrac{15}{20}=\dfrac{3}{4}

Therefore,

\dfrac{3}{5}+\dfrac{3}{20}=\dfrac{3}{4}

E . 2/3 + 1/12

\dfrac{2}{3}+\dfrac{1}{12}=\dfrac{2\times 4}{3\times 4}+\dfrac{1}{12}\\\\\dfrac{3}{5}+\dfrac{3}{20}=\dfrac{8+1}{12}=\dfrac{9}{12}=\dfrac{3}{4}

Therefore,

\dfrac{2}{3}+\dfrac{1}{12}=\dfrac{3}{4}
