For the following exercises, solve each inequality and write the solution in interval notation.
WARRIOR [948]

Answer:

The solution to the inequality |x-2|>10 in interval notation is given by -8<x<12

Step-by-step explanation:

An absolute value inequality |x-2|>10 is given.

It is required to solve the inequality and write the solution in interval form.

To write the solution, first solve the given absolute value inequality algebraically and then write it in interval notation.

Step 1 of 2

The given absolute value inequality is $|x-2|>10$.

The inequality can be written as

x-2<10 and x-2>-10

First solve the inequality, x-2<10.

Add 2 on both sides,

x-2<10

x-2+2<10+2

x<12

Step 2 of 2

Solve the inequality x-2>-10.

Add 2 on both sides,

x-2>-10

x-2+2>-10+2

x>-8

The solution of the inequality in interval notation is given by -8<x<12.

What was the cost of full coverage insurance in female in her 50s as a percentage of the same insurance in a male in his 30s if
ivolga24 [154]

Answer:

68.73%

Step-by-step explanation:

We have the insurance coverage amount for men of 30 years and for women of 50 years. Therefore, to find the percentage that represents the cost of coverage of the 50-year-old woman based on the cost of coverage of the man, we need to perform the following operation:

X_W = \frac{C_W}{C_M}*100\%

Where:

C_W: cost of coverage for a woman of 50 years.

C_M: coverage cost for a 30-year-old man.

X_W = \frac{\$819.73}{\$1192.64}*100\%

X_W = 68.73\%

Finally C_W represents 68.73% of C_W

10. The lengths of two sides of a right triangle are given. Find the length of the third side. Round to the nearest tenth if nec
bogdanovich [222]

Step-by-step explanation:

Length of third side

=  \sqrt{ {24}^{2}  +  {16}^{2} }  \\  =  \sqrt{576 + 256}  \\  =  \sqrt{832}  \\  = 28.84 \\   \approx \: 28.8 \: in

Or

Length of third side

=  \sqrt{ {24}^{2}  -  {16}^{2} }  \\  =  \sqrt{576 - 256}  \\  =  \sqrt{320}  \\  = 17.8885438 \\   \approx \: 17.9 \: in
