Answer:
10
Step-by-step explanation:
Using the process PEMDAS I got the answer 10.
168÷2^3+3^3-20
There are no parentheses so you solve the exponents first.
168÷8+9-20
Next, we do not multiply which makes division our second step.
This gives us 21+9-20.
Now we add 21+9 which gives us the sum of 30.
30-20 is equal to 10.

Answers
Answer: The correct answer is - 50.
Step-by-step explanation: :)
Answer:
50
Step-by-step explanation:
To calculate the mean, we do the total divided by the number of values. Therefore, to get 30, with 7 values, we need to have a total of 210. Currently, we have a total of 160, so Saturday needs to be 50, because 210-160=50.

An account with an initial balance of $4000 earns 6.5% interest for 5 years.
What is the ending balance?
Enter your answer in the box. $.
Answers
Answer:
The balance in the bank after 5 years of 6.5% interest is $5,300.
Step-by-step explanation:
*Presuming that this is not a compounding interest the interest would just multiply by the even balance.*
So every 5 years the balance earns 0.065 of 4,000 dollars.
This would make our equation:
4000 + (4000 x .065 x 5 )
= 4000 + (1300)
= 5300
The balance in the bank after 5 years of 6.5% interest is $5,300.

[[Please Explain]] The equation y - 2/3 = -2 (x - 1/4) is written in point-slope form. What is the equation in slope-intercept form? ³
O y = -2x - 1/6
O y = -2x + 7/6
O y = -2x + 5/12
O y = -2x - 11/12
Answers
y - 2/3 = -2 (x - 1/4)
First you distribute the -2 because it is the first order of operation
y - 2/3 = -2x + 1/2
Then you add 2/3 on both sides because we want to isolate y
y = -2x + 1/2 + 2/3
Then we combine like terms
y = -2x + 7/6

Mikey's family is taking a road trip. Their car can travel no more than 260 miles without needing to refill the gas tank. They have traveled 112 miles since they last filled the gas tank.
Mikey knows that the inequality representing this situation is 112 + x ≤ 260.
Select from the drop-down menu to correctly interpret the solution of this inequality.
Mikey's family can drive_____more miles before they need to refill the gas tank.
A. at most 148
B. at least 148
C. more than 372
D. more than 372
Answers
Answer:
A
Step by step:
you subtract 112 from 260 to isolate the variable. Then you get x is less than or equal to 148. Which means that the most miles that can be traveled is 148 miles before filling up.
Mikey's family can drive at most 148 more miles before they need to refill the gas tank. which is the correct answer would be option (A).
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
As per the given situation, the required inequality would be as
⇒ 112 + x ≤ 260
To isolate the variable, remove 112 from 260. The result is that x is less than or equal to 148.
⇒ 112 + x - 112 ≤ 260 - 112
⇒ x ≤ 148
This indicates that the maximum distance that may be traveled before filling up is 148 miles.
Therefore, his family can drive at most 148 more miles before they need to refill the gas tank.

Answer:
length= 35 feet and width= 10 feet
Step-by-step explanation:
You are given the perimeter of the rectangular deck is
90 feet.
2 x length + 2 x width = 90 You are also given that the deck's length is 5 feet less than 4 times it's width. That is length = 4 x width - 5
Those two equations are your system of linear equations. The second equation can be plugged into the first equation. This gives us an equation entirely in terms of width.
2x (4 x width - 5) + 2 x width =90
Distribute the 2 though
8 x width - 10 + 2 x width = 90
Combine like terms with width.
10 x width - 10 = 90
Add 10 to both sides.
10 x width = 100
Divide both sides by 10 width = 100
Now you can plug width into your original equation for length above. Recall: length = 4 x width - 5
Length = 4 x 10 - 5
Length = 40 - 5
Length = 35
Tina was observing the changing heights of a ball as it bounced over time. She graphed the function on this coordinate grid to show f(x), the height of the dropped ball, in feet, after its xth bounce.
Part A: What is f(3)? Explain what this value represents in the given context.
Part B: Tina said that a possible range for the given function is y > 0. Based on the given scenario, do you agree or disagree? If you agree, explain why the range is correct. If you disagree, what values should be the range for the given scenario?
Answers
The range for the given scenario is y≥0.
Given that, Tina graphed the function on the coordinate grid to show f(x), the height of the dropped ball, in feet, after its xth bounce.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Part A:
From the graph we can see that, for f(3) that is for 3 bounces the height is 4 feet.
Part B: Tina said that a possible range for the given function is y > 0.
From the graph we can see that for f(7) and f(8), the ball is almost at rest position. So the range can be y≥0.
Therefore, the range for the given scenario is y≥0.
