Answer:
9.6 cm
Step-by-step explanation:
Since the shapes are similar, we can write a proportion. Let x be the length of MN.
9/12 = 7.2/x Write a proportion.
9x = 12(7.2) Use cross products.
9x = 86.4 Multiply.
x = 9.6 Divide both sides by 9.
Side MN is 9.6 cm.
What is the domain of this function?
Domain = inputs = x = { 1 , 2 , 3 }
Range = outputs = y = { 2 , -1 }

Step-by-step explanation:
The management of Hartman Rent-A-Car has allocated $2.52 million to buy a fleet of new automobiles consisting of compact, intermediate-size, and full-size cars. Compacts cost $18,000 each, intermediate-size cars cost $27,000 each, and full-size cars cost $36,000 each. If Hartman purchases twice as many compacts as intermediate-size cars and the total number of cars to be purchased is 100, determine how many cars of each type will be purchased. (Assume that the entire budget will be used. Let x, y, and z denote the number of compact, intermediate-sized, and full-size cars purchased, respectively.)
Answer:
The number of compact cars = x = 30 cars
The number of intermediate-sized car = y = 60 cars
The number of full-size cars purchased = z = 10 cars
Step-by-step explanation:
Let us denote:
the number of compact car = x
the number of intermediate-sized car = y
the number of full-size cars purchased = z
The total number of cars to be purchased is 100.
Hence:
x + y + z = 100...........Equation 1
If Hartman purchases twice as many compacts as intermediate-size cars
y = 2x
So: x + 2x + z = 100..........Equation 2
= 3x + z = 100
z = 100 - 3x
Compacts cost $18,000 each, Intermediate-size cars cost $27,000
Full-size cars cost $36,000 each.
Assume that the entire budget will be used.
Hence,
x × $18,000 + y × $27,000 + z × $36,000 = $2,520,000.
18000x + 27000y + 36,000z = $2,520,000.....Equation 4
Substitute 100 - 3x for z and y = 2x in Equation 4
18000x + 27000(2x) + 36,000(100 - 3x) = $2520000
18000x + 54000x + 3,600,000 -108000x = $2520000
72000x -108000x + 3,600,000 = $2,520,000
= $3,600,000 - $2,520,000 = 108000x - 72,000x
$1,080,000 = 36,000x
Divide both sides by $36,000
x = $1080000/36000
x = 30
From the above:
y = 2x
y = 2 × 30
= 60
z = 100 - 3x
= 100 - 3 × 30
= 100 - 90
= 10
Therefore,
The number of compact cars = x = 30 cars
The number of intermediate-sized car = y = 60 cars
The number of full-size cars purchased = z = 10 cars

Which expression represents the total volume of the two storage spaces
Answer:
S^3+12
Step-by-step explanation:
The big block shows three s then you have to simplify that with 12ft^3
The expression that represents the total volume of the two storage spaces is s³+ 12
What is the total volume?The total volume of the two storage spaces is the sum of the smaller storage space and the larger storage space.
Volume = width x height x length.
Volume of the larger storage space = s x s x s = s³
The total volume of the two storage spaces = s³+ 12

The record low temperature in Pittsburgh, PA is -22°F. The record high is 103°F. What is the difference in the record high and the record low temperatures?
Answer:
The difference in the record high and the record low temperatures is 125°F
Step-by-step explanation:
Given a quantity T that varies in time, say T1 and T2, being T1 the initial value and T2 the final value.
The change or difference between the final and the initial values is:
T=T2-T1
The record low temperature in Pittsburgh, PA is T1=-22°F while its record high is T2=103°F
The difference is:
T=103°F - (-22°F)
Note both negative signs multiply to produce a positive sign, and a sum instead of a subtraction:
T=103°F + 22°F = 125°F
The difference in the record high and the record low temperatures is 125°F
solve equation with variable on both sides

Answer: Converse: If the candy has 350 calories, the candy is chocolate, False. There is another 350 calorie candy.
Inverse: If the candy does not have 350 calories, the candy is not chocolate. True In this case, the evidence in the chart supports this. The inverse is not always true.
Contrapositive: If the candy does not have 350 calories, the candy is not chocolate. True The evidence in the chart supports this statement, and the Contrapositive is generally considered a logical equivalent of the original.
Step-by-step explanation:
You need to have a basic frame for converting the original statement to the other forms such as
Original: If P, then Q
Converse: If Q, then P Just reverse the parts
Inverse: If not P then not Q In the same order, make both negative, add "not"
Contrapositive: If not Q then not P Reverse the order of the original and make both negative.

The actual volumes of quart-size jars of Hellmann's mayonnaise are uniformly distributed from 31.58 to 32.51 fluid ounces. Find the standard deviation in volumes of quart-size Hellmann's mayonnaise jars (in fluid ounces). NOTE: There are 32 fluid ounces in a quart.
Answer:
0.27
Step-by-step explanation:
The standard deviation of a uniform distribution is:
σ² = (b − a)² / 12
σ² = (32.51 − 31.58)² / 12
σ² = 0.0721
σ = 0.268
Rounded to the hundredths place, the standard deviation is 0.27.
To solve this question, we use concepts of the uniform probability distribution.
Using this, we get that the standard deviation in volumes of quart-size Hellmann's mayonnaise jars is of 0.2685 fluid ounces.
Uniform probability distribution:
An uniform distribution has two bounds, a and b.
The standard deviation is:
[tex]S = \sqrt{\frac{(b-a)^2}{12}}[/tex]
The actual volumes of quart-size jars of Hellmann's mayonnaise are uniformly distributed from 31.58 to 32.51 fluid ounces.
This means that [tex]a = 31.58, b = 32.51[/tex]
Find the standard deviation in volumes of quart-size Hellmann's mayonnaise jars (in fluid ounces).
[tex]S = \sqrt{\frac{(32.51 - 31.58)^2}{12}} = 0.2685[/tex]
Thus, the standard deviation is of 0.2685 fluid ounces.

what are the coordinates of (4,-3) after a translation 3 units right and 6 units up
Answer:
(7,3)
Step-by-step explanation:
what is the answer? pls help
Answer:
for the line to have a constant slope, the difference of every y- ordinate with the last ordinate has to be equal
to check this, we will use the following formula
y4 - y3 = y2 - y1
if both the LHS and the RHS are equal, the slope is constant and is irregular otherwise
5 - 8 = 7 - 3
-3 = 4
LHS ≠ RHS
Since LHS is not equal to RHS, the slope is NOT constant and hence keeps increasing or decreasing irregularly
Therefore, option 4 (Not a line) is correct
Answer:
it is not a constant line
Step-by-step explanation:
each x value increases by 1, but the y values are all over the place and are in no order.
