The average adult spends 7 to 8 hours sleeping. About 20% of the time you sleep is spent in rapid eye movement (REM) sleep which is associated with dreaming. Write and Solve a compound inequality to determine how much time is spent in REM sleep for the average adult?
Answer:
.20(7) ≤ x .20(8)
Step-by-step explanation:
let 'x' = amount of time in REM sleep
Answer:
1.4[tex]\leq[/tex] x [tex]\leq[/tex] 1.6
Step-by-step explanation:
You can start off by writing the inequality that 7(.20) is less than/equal to x which is less than/equal to 8(.20). Then, you just multiply the numbers and you have the 20% that you spend in REM sleep.

PLEASE HELP!! I’ve got a car with an internal volume of 12,000 L. If I drive my car into the river and it implodes, what will be the volume of the gas when the pressure goes from 760 mmHg to 141.82 kPa?
Answer:
V2 = 8571.43L
Step-by-step explanation:
To solve for the V2, We can use V2 = P1V1 / P2
= 1.0 atm × 12,000 L / 1.4 atm
= 12,000 L / 1.4 atm
= 8571.43 L

Answer:
A
A
Step-by-step explanation:
8) because of the rules of angles we know that all angles found on a line are equal to 180 degrees, and all angles opposite one another are equal. because of this A is not possible. 90 and 40 do not add up to 180 degrees, and are not equivalent to each other.
9) using the same rules as above, we know that the two angles have to add up to 180 degrees (they can't be equal this time). A is not possible.

The population of a city is expected to decrease by 6% next year. If x represents the current population, write an expression that represents the expected population next year.
Given:
Current population = x
The population of a city is expected to decrease by 6% next year.
To find:
The expression that represents the expected population next year.
Solution:
We have,
Current population = x
Decrease rate = 6%.
Expected population next year = Current population - 6% of Current population
=[tex]x-\dfrac{6}{100}x[/tex]
=[tex]x-0.06x[/tex]
=[tex]0.94x[/tex]
Therefore, the expression for the expected population next year is 0.94x.
Three friends go grocery shopping together, and each guys the same kinds of strawberries. Akio buys 2 pounds and pays 1.50. Gordon buys 3 pounds and pays 2.25. Maria buys 4 pounds and pays 3.00.
Answer: Graph B
Step-by-step explanation:
The unit price for the strawberries is:
= 1.5 / 2
= $0.75 per pound
Graph B is the right graph as it uses a unit price of $0.75 per pound for strawberry price. This is why it has points of the graph that mirror the friends purchases such as (2, 1.5) , (3, 2.5) and (4, 3).

PLEASE HELP!!!! On average, Jack can fold his laundry in 30 minutes, but, depending on how much laundry he has, his time can vary from the average by 10 minutes.
Which absolute value equation can be used to calculate Jack's maximum and minimum time to fold his laundry?
Let x represent the maximum and minimum time.
|x−30|=10
|x+10|=30
|x−10|=30
|x+30|=10
Answer:
I think it is the third choice
The absolute value equation can be used to calculate Jack's maximum and minimum time to fold his laundry is, |x−30|=10. So, Option A is correct
What is an Equation ?An equation is a mathematical term, which indicates that the value of two algebraic expressions are equal. There are various parts of an equation which are, coefficients, variables, constants, terms, operators, expressions, and equal to sign.
For example, 3x+2y=0.
Types of equation
1. Linear Equation
2. Quadratic Equation
3. Cubic Equation
Given that,
On average, Jack can fold his laundry in 30 minutes
How much laundry he has, his time can vary from the average by 10 minutes
So, maximum time can be 40 minutes
And minimum time can be 20 minutes
Therefore, The result is |x-30| =10

You plan to go snowboarding this weekend in Colorado. The resort charges $20.75 per hour addition to a $35 deposit to rent a snowboard. Solve linear equation to find the total cost to rent the snowboard from 8:30 a.M. To 12:30 p.M.
Answer:
$160.75
Step-by-step explanation:
Step one:
given data
The resort charges $20.75 per hour in addition to a $35 deposit to rent a snowboard
The time spent from 8:30 am to 12:30 pm = 4hours
Step two:
Let the number of hours be and the total cost be y
Now the expression for the situation can be represented as
y= 20.75+35x
for x= 4
y=20.75+35(4)
y=20.75+140
y=160.75

Sam builds 360 toys in 8 hour. At that rate,how many toys would he build in 4 minutes
Answer:
He can build 3 toys in 4 minutes.
Step-by-step explanation:
Divide 360 by 8 since you are dividing it first to get the number of toys he can build in an hour. As a result, he can build 45 toys in an hour. Divide that number by 15 since 4 times that number equals an hour. You should get 3 toys as your final result.
For easier explanation, multiply 8 and 15 together to get 120 for better understanding. Divide that number from 360 to get the same answer.
Solve the equation. y/8 = 5. y=
Answer:
y = 40
Step-by-step explanation:
Given
[tex]\frac{y}{8}[/tex] = 5 ( multiply both sides by 8 to clear the fraction )
