Answer:
The missing value is 6!
Step-by-Step Explanation:
First, we know that there are 4 values in total, so we must multiply the mean, 7, by 4 to get the total sum of all the values. (7*4=28)
Now, we can write this as a function, where we can represent the missing value as 'x'.
[tex]4+5+13+x=28[/tex]
In order to get the missing value, we must solve the equation.
Step 1: Simplify.
[tex]4+5+13+x=28\\22+x=28[/tex]
Step 2: Subtract 22 from both sides.
[tex]22+x=28\\22+x-22=28-22\\x=6[/tex]
x is equal to 6, which means the missing volume of gas is 6!

The variable Q varies inversely as the cube of V. FK is the constant of variation, which equation represents this situation?
A. qv^3=k
B. q^3v=k
C. q/v^3=k
D. q^3/v=k
Step-by-step explanation:
When 2 variables are inversely proportional to each other, their product is a constant.
Since Q and V³ are inversely proportional to one another, QV³ = k. (B)

Answer:
3/2 or 1 1/2
Step-by-step explanation:
5÷3 1/3
5/1 ÷ 10/3 because you have to get it into an improper fraction form in order to divide
5/1 × 3/10 because you have to multiply the first number by the reciprocal
5 and 10 cancel out so you would have 2 at the bottom

can someone help simplify the following expression. 7t -3t + 4
A 4t + 4
B 7t - 1
D 10t + 4
C10 + 4
Select the correct answer.
Determine which equation has the same solutions as the given equation.
x2 − 10x − 11 = 0
A.
(x − 5)2 = 21
B.
(x − 10)2 = 21
C.
(x − 10)2 = 36
D.
(x − 5)2 = 36
Answer:
D. [tex]\displaystyle (x - 5)^2 = 36[/tex]
Step-by-step explanation:
All you are doing is converting this Quadratic Equation to a Vertex Equation in Vertex Form by completing the square:
[tex]\displaystyle [\frac{b}{2}]^2 \\ \\ x^2 - 10x - 11 = 0 → x^2 - 10x + 25 - 36 = 0→ (x - 5)^2 - 36 = 0 \\ \\ (x - 5)^2 = 36[/tex]

Teresa is going with her family to watch
professional barrel racers. Her family
buys 6 tickets. They have a coupon for
$1.50 off each ticket. They pay $52.50
altogether for their tickets. Write an
equation that you could use to represent
the situation. What is the price of a ticket
before using the coupon?
Answer:
6 * (x - 1.50) = 52.50 ; 10.25
Step-by-step explanation:
Given that :
Number of tickets purchased = 6
Coupon off per ticket = 1.50
Total Amount paid for tickets = $52.50
Let x = initial price of ticket :
Number of tickets purchased * (Initial ticket price - coupon) = total amount paid
6 * (x - 1.50) = 52.50
6x - 9 = 52.50
6x = 52.50 + 9
6x = 61.50
x = 61.50 / 6
x = 10.25
Hence, initial price of ticket = $10.25

Amanda buys 4 tickets to the baseball game for $24 each. Which equation
shows the closest estimate of the total amount Amanda spends?
Which equation shows the closest estimate of the total amount Amanda spends
Answer:
$96
Step-by-step explanation:
Given that,
The total number of tickets = 4
Cost of each baseball = $24
We need to find the equation that shows the closest estimate of the total amount Amanda spends.
Total cost = No. of tickets × Cost of each baseball
= 4×24
= $96
Hence, the total cost is $96.

A stack of books is 5 feet 5 inches high. How high is it in inches?
Well first, you have to know that there are 12 inches in a foot so, that's 12 / 3 = 4, so that means that for every foot, there are 4 books. The books are 5 feet tall so 4 x 5 = 20. Your answer is: 20 books are in a stack.
Answer:
Step-by-step explanation: I would do 5x12 because there are 12 inches in one foot so 5x12 is 60 so there is 60 inches

Step-by-step explanation:
let x be the unknown volume
5/7=50/x
x=70
Answer:
137.2 m³
Step-by-step explanation:
Given the ratio of sides a : b , then
ratio of volumes = a³ : b³
Here ratio of sides = 5 : 7 , then
ratio of volumes = 5³ : 7³ = 125 : 343
let x be the volume of the larger prism then by proportion
[tex]\frac{50}{125}[/tex] = [tex]\frac{x}{343}[/tex] ( cross- multiply )
125x = 17150 ( divide both sides by 125 )
x = 137.2
That is volume of larger prism is 137.2 m³
Seema is travelling to Kenya. She travels a distance of 8,300 km by plane to Lagos and then another 5,500 km to Nairobi. Both planes fly at an average speed of 1,200 kmh-1. What is her total flight time in hours and minutes, to the nearest minute?
Answer: 11 hours 30 minutes
Step-by-step explanation:
Total flight distance:
= 8,300 + 5,500
= 13,800 km
Flight time = Distance / Speed
= 13,800 / 1,200
= 11.5 hours
= 11 hours 30 minutes

Step-by-step explanation:
Pythagorean theorem converse
Answer:
The value of x is 13.7.
Step-by-step explanation:
☆We are going to use the Pythagorean theorem to solve this.
☆Pythagorean Theorem:
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
☆Remmeber: a = leg, b = leg, c = hypotenuse or the diagonal.
☆Let's plug in according to the pythagorean theorem and solve!
[tex] {a}^{2} + {b}^{2} = {c}^{2} \\ {x}^{2} + {9.2}^{2} = {16.5}^{2} \\ {x}^{2} + 84.64 = 272.25 \\ \frac{ \: \: \: \: \: \: \: \: - 84.64 = - 84.64}{ {x}^{2} = \sqrt{187.61} } \\ x = 13.7[/tex]
