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!

Jasmine is taking out a small business loan for her floral shop. She plans to apply for a $30,000 loan with a 5-year term and a 3.75% interest rate. She is unsure of her expected monthly profits, so she wants to know the benefit of a smaller loan. Using the loan amortization formula, how much money would Jasmine save over the life of the loan if she were to borrow $10,000 less?
Answer:
Monthly pay = int. rate / 12 months * cost of car after downpayment / (1-(1+ int. rate/12 months)^( - term length of loan )
Step-by-step explanation:
Just plug in your numbers:
M = 0.0375/12 * 30000/(1-(1+.0375/12)^60)
since 5 years is 60 months

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.
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

Complete the pairs of corresponding parts if △RST ≅ △TXY.
∠STR =
∠ XYT
∠ TXY
∠ XTY
Answer:
∠STR is associated with ∠ XYT
Therefore, we conclude that:
∠STR = ∠ XYTStep-by-step explanation:
Given
△RST ≅ △TXY
To determine:
∠STR = ?
As
△RST ≅ △TXY
So the triangles △RST and △TXY are congruent to each other.
We know that congruent triangles have equal corresponding parts.Please check the attached graph.
From the graph, it is clear that:
∠STR is associated with ∠ XYT
so
∠STR = ∠ XYT
Therefore, we conclude that:
∠STR = ∠ XYTcan someone help simplify the following expression. 7t -3t + 4

The soccer team is planning to sell health bars for a fundraiser. The prices of purchasing health bars from two different companies are represented by the system of equations shown, where x is the number of bars purchased and y is the total cost in dollars. Company A: y=0.75x Company B: y=10+0.50x How many bars would the team need to purchase from each company in order for the total cost to be equal?
Answer:
40 bars
Step-by-step explanation:
Where x = Number of bars purchased by each team
We solve this question by equating both Equations from Company A to Company B
Company A = Company B
0.75x = 10 + 0.50x
Collect like terms
0.75x - 0.50x = 10
0.25x = 10
x = 10/0.25
x = 40 bars
Hence, each team need to purchase 40 bars from each company
Answer:
Step-by-step explanation:
40

What is the surface area of a rectangular prism with measurements of 5, 7, and 4?
Answer:
166
Step-by-step explanation:
A cube is a rectangular prism where all its sides are the same. The formula to find the surface area of a rectangular prism is A = 2wl + 2lh + 2hw, where w is the width, the l is the length, and the h is the height.
A=2(wl+hl+hw)=2·(7·5+4·5+4·7)=166
A = 166

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

Point S lies between points R and T on Line segment R T. A line contains points R, S, T. The space between R and S is 2 x. The space between S and T is 3 x. If RT is 10 centimeters long, what is ST? 2 centimeters 4 centimeters 6 centimeters 8 centimeters
Answer:
6 cm
Step-by-step explanation:
Given that:
A line that contains the points R, S and T.
Distance between R and S = [tex]2x[/tex]
Distance between S and T = [tex]3x[/tex]
To find:
The distance between S and T = ?
Solution:
The given situation and dimensions can be represented in the form of a diagram as shown in the attached diagram.
As per given statement and in the diagram, we can deduce that the sum of distance between R and S, S and T is equal to distance between R and T.
i.e. RS + ST = RT
[tex]2x + 3x = 10\\\Rightarrow 5x=10\\\Rightarrow x = 2[/tex]
ST = 3[tex]x[/tex] = 3 [tex]\times[/tex] 2 = 6 cm
Therefore, the answer is:
Distance between S and T is 6 cm.
If the space between R and S is 2x, the space between S and T is 3x, and RT is 10 centimeters long, then ST is 6 centimeters
Point S lies between points R and T on Line segment RT
RT = RS + ST
The space between R and S is 2x
That is, RS = 2x
The space between S and T is 3x
That is, ST = 3x
RT is 10 centimeters long
RT = 10cm
Substitute RT = 10, ST = 3x and RS = 2x into the equation RT = RS + ST
10 = 2x + 3x
10 = 5x
x = 10/5
x = 2
If x = 2, then
ST = 3x
ST = 3(2)
ST = 6 centimeters

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
