$457.54 total
The required total monthly cost of owning and maintaining a car, given the information shown, is $457.54.
What is arithmetic?In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
Here,
To find the total monthly cost of owning and maintaining a car, we need to add up the monthly car payment, the monthly insurance cost, the average cost of gasoline per month, and the average maintenance cost per month.
Adding these values, we get:
Total monthly cost = Monthly car payment + Monthly insurance cost + Average cost of gasoline per month + Average maintenance cost per month
= $274.96 + $77.00 + $89.20 + $16.38
= $457.54
Therefore, the total monthly cost of owning and maintaining a car, given the information shown, is $457.54.

Why does the inequality sign have to be flipped when multiplying and dividing by a negative number like in −2x > 10?
Answer:
When you multiply both sides by a negative value you make the side that is greater have a "bigger" negative number, which actually means it is now less than the other side! This is why you must flip the sign whenever you multiply by a negative number.

1. Mr. Miller is building a dollhouse
for his daughter Juanita. He is
designing the dollhouse after a
colonial home with a height of
10 yards. If he wants the
dollhouse to be 4 feet tall, what
scale should he use?
A. 1 foot:2-yards
25
B. 2 feet:15 yards
1
C. 2 feet:7- yards
2
et 7
D. 1 foot:5 yards
Answer:
1 ft : 2.5 yd or 1 ft : 2 1/2 yd
Step-by-step explanation:
He wants a real dimension of 10 yards to be represented by a scale dimension of 4 ft.
4 ft : 10 yd
Divide both sides by 4.
1 ft : 2.5 yd or 1 ft : 2 1/2 yd
A monument is made in the form of a pyramid with a regular pentagon as a base. Each side of the base is 3 m long and has a slant height of 24 m. If the monument is to be covered by a metal, how many square meters of metal is needed to cover the faces of the pyramid?
Answer:
180m²
Step-by-step explanation:
In order to solve this question, we have to find the area of the pyramid with a pentagonal base.
This pyramid has slant height = 24m
Since the base is a pentagon, it means it is 5 sided.
Each side of the base = 3m
The area of the pyramid = 1/2 × 5(side length) × slant height
= 1/2 × 5(3) × 24
= 180m²
Therefore, the square meters of metal needed to cover the faces of the pyramid = 180m²

4(8x + 4) – 20 = -20
Answer:
x = -1/2
Step-by-step explanation:
4 (8x + 4) -20 = -20
=> 32x + 16 -20 = -20
=> 32x - 4 = -20
=> 32x = -20 + 4
=> 32x = -16
=> 32x/32 = -16/32
=> x = -1/2
So, x is -1/2 or -0.5
To simplify 4(8x+4), multiply 4 by 8x and 4.
(4×8x) + (4×4) = 32x and 16
32x + 16 - 20 = -20
Subtract 16 from both sides.
You should end up with 32x - 20 = -36
Add 20 to both sides.
You should end up with 32x = -16
-16 ÷32 = -1/2
x = -1/2

The mean score for a math test taken by Class A is 84, with the scores ranging from 78 to 94. The mean score for the same math test taken by Class B is 76, with the scores ranging from 68 to 88. Which BEST compares the scores of the two classes?
A) The highest score for the test was in Class B.
B) On average, the scores of Class A are lower than Class B.
C) On average, the scores of Class B are lower than Class A.
D) The scores of Class A vary more than the scores of Class B.
D) 22
Answer:
C
Step-by-step explanation:
mean score class A= 84
mean score class B= 76
the average/mean scores of class B< average/mean scores of class A
76<84
by process of elimination,
B is false- the mean scores class A are not lower than class B
A is false- the highest score is in class A with a score of 94 (highest score in class B=88)
D- not enough information is provided to determine coefficient of variation

Nia and Trey both had a sore throat so their mom told them to gargle with warm salt water.
Nia mixed 1 teaspoon salt with 3 cups of water.
Trey mixed 12 teaspoon salt with 112 cups of water.
Nia tasted Trey’s salt water. She said,
“I added more salt so I expected that mine would be more salty, but they
taste the same.”
Explain why the salt water mixtures taste the same.
Answer:
both mixes used the same ratio of salt to water.
Step-by-step explanation:
Nia used double Trey's recipe, doubling both the salt and the water. So, the ratio of salt to water was the same in each mix.
__
Trey's recipe: (1/2 tsp salt : 1.5 cups water)
Nia's recipe: 2(1/2 tsp salt : 1.5 cups water) = 1 tsp salt : 3 cups water

Write an equation of the line containing the point (6,-4) and perpendicular to.the line y=-2x-3
Answer:
[tex]\displaystyle y = \frac{1}{2} x - 7[/tex]
Step-by-step explanation:
We want to determine the equation of the line that passes through the point (6, -4) and is perpendicular to the line:
[tex]\displaystyle y = -2x - 3[/tex]
Recall that the slopes of perpendicular lines are negative reciprocals of each other.
The slope of the given line is -2.
Hence, the slope of the perpendicular line is 1/2.
Therefore, the slope of our new line is 1/2. We also know that it passes through the point (6, -4). Since we are given the slope and a point, we can consider using point-slope form:
[tex]\displaystyle y - y_1 = m(x - x_1)[/tex]
Where m is the slope and (x₁, y₁) is a point.
Let (6, -4) be (x₁, y₁). Substitute:
[tex]\displaystyle y - (-4) = \frac{1}{2}(x - (6))[/tex]
Simplify. Distribute:
[tex]\displaystyle y + 4 = \frac{1}{2} x - 3[/tex]
And subtract 4 from both sides:
[tex]\displaystyle y = \frac{1}{2} x - 7[/tex]
In conclusion, the equation of our line is:
[tex]\displaystyle y = \frac{1}{2} x - 7[/tex]

64 = x3
what value of x makes this equation true ?
Answer:
x = 4.
Step-by-step explanation:
64 = x^3
x^3 = 64
[tex]\sqrt[3]{x^3} = \sqrt[3]{64}[/tex]
[tex]\sqrt[3]{x^3} = \sqrt[3]{4 * 4 * 4}[/tex]
[tex]\sqrt[3]{x^3} = \sqrt[3]{4^3}[/tex]
x = 4.
Hope this helps!
Answer:
x = 3
The cube root of 64 is 4 because 4 x 4 x 4 = 64.
Cube roots have 3 identical factors, while square roots have 2 identical factors.

Let's say she does the absolute minimum and buys 4 bags
Each bag has 7 servings, so there are 7*4 = 28 servings total.
I'm assuming each of the 30 guests gets one serving only. If so, then there wouldn't be enough food to go around (30-28 = 2 people are left out).
This means she cannot round x = 4.3 to x = 4. Instead, she must round up to get x = 5 as the lowest x value possible.
7x = 7*5 = 35 servings clears the hurdle.
So in short, x = 4 does not work in [tex]7x \ge 30[/tex] but x = 5 does work in

Alternatively, you could plug in x = 4 into [tex]x \ge 4.3[/tex] to get [tex]4 \ge 4.3[/tex] which is not a true statement. So x = 4 is not a solution to
