Answer:

9.8

Step-by-step explanation:

Using angle bisector theorem,

multiplying both sides by 1.5, the answer is approximately 9.8.

A TV costs $125.67 with a discount of 15% and 8.5% tax. What is the total that you will have to pay?

Usimov [2.4K]

Answer:

The total you have to pay for the TV is $115.9

Step-by-step explanation:

When we have a discount we have to make a substraction, when we have tax we have to sum so:

$125.67 * 15 % = 18.85

125.67 - 18.85 = 106.82

Now we have to add the tax

106.82 * 8.5% = 9.08

106.82 + 9.08 = 115.9

What is the difference of the fractions? Use the number line to help find the answer.

Doss [256]

Answer:

Option 'b' i.e. -11/20 is the correct option.

Thus,

$\frac{1}{5}-\frac{3}{4}=-\frac{11}{20}$

Step-by-step explanation:

Given the expression

$\frac{1}{5}-\frac{3}{4}$

Determining the difference of the fractions

$\frac{1}{5}-\frac{3}{4}$

The Least Common Multiplier of 5, 4 is 20. Thus, adjust the fractions based on the L.C.M.

$\frac{1}{5}-\frac{3}{4}=\frac{4}{20}-\frac{15}{20}$

Apply the fraction rule: $\frac{a}{c}-\frac{b}{c}=\frac{a-b}{c}$

$=\frac{4-15}{20}$

Add the number: 4-15 = -11

$=\frac{-11}{20}$

Apply the fraction rule: $\frac{-a}{b}=-\frac{a}{b}$

$=-\frac{11}{20}$

Please check the attached figure, where the pointing-down arrow is representing the correct answer which is -11/20.

Therefore, option 'b' i.e. -11/20 is the correct option.

Thus,

$\frac{1}{5}-\frac{3}{4}=-\frac{11}{20}$
