Alicia cashed her paycheck and used half her earnings to take three friends to dinner. She spent $42.15 on dinner and she brought home more than $20.00. Write an inequality to represent the situation, using x to represent the amount of Alicia's paycheck

Answers

If you would like to write an inequality to represent the situation, you can do this using the following steps:

x ... the amount of Alicia's paycheck

x/2 - $42.15 >= $20
x/2 >= $20 + $42.15
x/2 >= $62.15 /*2
x >= $62.15 * 2
x >= $124.3

The correct result would be x >= $124.3.

An odd number on a spinner with equal sized sections labeled 1-8A. a number less than 4
B. a number greater than 4
C. a multiple of 3
D. an even number

Answers

probability is
(desired outcomes)/(total possible outcomes)
total possible is 8 since 8 total spaces

A. number les than 4, there are 3 numbers (1,2,3) so
3/8 os probability

B. number greater than 4, ther are 4 (5,6,7,8), so 4/8=1/2 is probability

C. multiplule of 3, there are 2 (3,6) so 2/8=1/4 is probability

D. even number, there are 4 (2,4,6,8) so 4/8=1/2 is probability

A. 3/8
B. 1/2
C. 1/4
D. 1/2

Water boils at different temperatures at different elevations. The boiling temperature of water is 212 degrees * F sea level (0 feet ) but drops about 1.72 degrees * F for every 1,000 feet of elevation. Write a formula for the boiling point at a given elevation. Then solve the formula for the elevation when the boiling point for water is 190 degrees F.

Answers

Answer:

The elevation when the boiling point of water is $190$ ° $F$ is 12790.70 feet

Step-by-step explanation:

Let every 1,000 feet of elevation be $x$ . Hence, we can write

$T = 212$ $- 1.72x$

Where $T$ is the boiling temperature of water at different elevations

Now, to the determine the elevation when the boiling point of water is $190$ ° $F$ .

We will determine $x$ by putting $T = 190$ ° $F$ .

Hence,

$T = 212$ $- 1.72x$

$190$ $= 212$ $- 1.72x$

$190 - 212$ $= - 1.72x$

$- 22$ $= - 1.72x$

$22 = 1.72x\nx = (22)/(1.72) \nx = 12.79070$

Since $x$ represents every 1,000 feet of elevation, then the elevation when the boiling point of water is $190$ ° $F$

$12.79070$ × $1000\n$ $= 12790.70$ feet

Hence, the elevation when the boiling point of water is $190$ ° $F$ is 12790.70 feet

you would do tanƟ = 9/12
tan^-1(9/12) = Ɵ
Ɵ = 36.87 degress
make sure your calculator is in degree mode

The answer is 36.87 degree. I hope it helps!
