Jon drove 365 on 20 gallons of gas. How many miles did he get per gallon?
Answer:
18.25
Step-by-step explanation:
365 ÷ 20 = 18.25
Jon drove 365 miles on 20 gallons of gas, so to find out how many miles he got per gallon, you divide 365 miles by 20 gallons. The result is 18.25 miles per gallon.
Explanation:To solve this problem, you need to divide the total number of miles that Jon drove by the number of gallons of gas he used. This is because the miles per gallon is calculated by dividing the total miles driven by the amount of gas used.
So, in this case, you would do the following calculation: 365 miles ÷ 20 gallons = 18.25 miles per gallon
This means that Jon got 18.25 miles per gallon of gas.

What is the midpoint between (-2, -3) and (1, 0.5)
Answer:
(-1/2,-1.25)
Step-by-step explanation:
Once you plot the points, you should be able to find the midpoint formula.
The midpoint between the points (-2, -3) and (1, 0.5) is (-0.5, -1.25).
To find the midpoint between two points, you average the x-values and the y-values of the given points separately. The formula for the midpoint M between two points P1(x1, y1) and P2(x2, y2) is
M = ((x1 + x2) / 2, (y1 + y2) / 2)
Applying this to the given points (-2, -3) and (1, 0.5), we calculate the midpoint as follows:
Average the x-values:
(-2 + 1) / 2 = -0.5
Average the y-values:
(-3 + 0.5) / 2 = -1.25
Please answer right away
Answer:
$29000 with a margin of error of $5000
Step-by-step explanation:
We have that the midpoint between the given values is
(X1+X2) / 2 = ($34000+$24000)/2 = $29000
We have that the midpoint between the given values would be
(X2-X1)/2=($34000-$24000)/2=$10000/2=$5000
So I can write that approach as $29000 with a margin of error of $5000

The Roosevelts and the Jaspers live in the same city and pay the same sales
tax rate, and both families made $16,000 in taxable purchases last year, if the
Roosevelts made $91.000 and the Jaspers made 37000 last year, is the
sales tax in their city an example of a regressive tax?
Answer:
Yes, because the Jaspers paid a higher percentage of their income in sales tax than the Roosevelts did.
Step-by-step explanation:
Regressive tax is a constant, instead of a percentage of income. Those with a lower income would pay a higher percentage of their income. Both families, irregardless of income, paid $16,000 in taxes.
APEX
Answer:
Yes, because the Jaspers paid a higher percentage of their income in sales tax than the Roosevelts did.
Step-by-step explanation:
A regressive tax is one that collects a smaller percentage of the income as the person earns more. That is to say that at higher profit or higher income, the percentage of taxes that must be paid on the total tax base is lower.
In this way the poor are relatively more affected than the rich.
The Roosevelts made $91.000 (high income)
The Jaspers made $37.000 (low income)
But both paid the same sales tax rate of $16,000.
This type of tax does not have a redistribution effect of wealth. On the contrary, if it is a very high tax, it can accentuate inequality in a society.

5 * 20 = 100
100 - 10 = 90 which equals a angle in a right angle triangle
Answer:
The value of x is 11 ⇒ answer B
Step-by-step explanation:
* lets check the properties of the square
- Its four aides are equal
- Its four angles are equal and the measure of each one is 90°
- Its diagonals bisect its vertices
∵ BD is a diagonal of the square
∴ BD bisects angle B
∴ m∠ABD = m∠CBD
∵ B is a vertex of the square
∴ m∠B = 90°
∴ m∠ABD = m∠CBD = 90 ÷ 2 = 45°
∵ m∠ABD = (5x - 10)°
∴ (5x - 10)° = 45° ⇒ add 10 to each side
∴ 5x = 55 ⇒ divide both sides by 5
∴ x = 11
* The value of x is 11

A dilation produces a smaller figure. Which is a possible scale factor?
A dilation producing a smaller figure requires a scale factor less than 1. If the scale factor is 1/2, the model size is half the actual size. By setting up and solving a proportion, actual dimensions can be calculated.
Explanation:When a dilation results in a smaller figure, the scale factor used is less than 1. Think of the scale factor as a fraction where the actual size is the denominator and the model size is the numerator. For instance, a scale factor of 1/2 would mean that the model is half the size of the actual figure.
For a practical example: if we have a scale factor of 1:4 and the scale measurement is 4, the actual dimension can be found by setting up a proportion as 1/4=4/x, solving for x would give us the actual dimension, which in this case would be 16.

Find area of a cone
Show work
Answer: 138.16 in²
Step-by-step explanation:
You need to use this formula to calculate the surface area of the cone:
[tex]SA = \pi r^2 + \pi rl[/tex]
Where "r" is the radius, "h" is the height and "l" is the slant height.
To find the height you need to use the Pythagorean Theorem:
[tex]a^2=b^2+c^2[/tex]
Where "a" is the hypotenuse and "b" and "c" are the legs of the triangle.
In this case:
[tex]a=l=7in\\\\b=r=\frac{8in}{2}=4in\\\\c=h[/tex]
("r" is the radius and "h" is the height and "l" is the slant height.)
You need to find "h". Then, solving for "h", you get:
[tex]h=\sqrt{(7in)^2-(4in)^2}\\h=5.74in[/tex]
Then, substituting values into the formula, you get:
[tex]SA = (3.14)(4in)^2 + (3.14) (4in)(7in)=138.16in^2[/tex]

a fish tank is shaped like a rectangular prism. It has a length of 5 feet, a width of 2 feet, and a height of 3 feet. what is the volume of the fish tank?
Answer:
30 ft
Step-by-step explanation:
It is 30 because to find the volume of a rectangular prism, you do
length x width x height.
So, 5 x 2 x 3 = 30.
To find the volume of a rectangular prism, multiply its length, width, and height. Thus, the volume of the fish tank measuring 5 feet in length, 2 feet in width, and 3 feet in height is 30 cubic feet.
Explanation:The volume of a rectangular prism such as a fish tank can be calculated by multiplying its length, width, and height together. For a fish tank with a length of 5 feet, a width of 2 feet, and a height of 3 feet, the volume calculation would look like this:
Volume = Length × Width × Height
Volume = 5 ft × 2 ft × 3 ft
Volume = 10 ft × 3 ft
Volume = 30 ft³
Therefore, the volume of the fish tank is 30 cubic feet.

Answer:
A: 700
B: 6400
C: 50
Step-by-step explanation:
A: You can multiply by 5
B: You can just multiply by 20.
C: Every 10% is 5, because 15(30%)/3 is 5. 5 times 10 is 50.
Answer:
a. h = 700
b. j = 6400
c. g = 50
Step-by-step explanation:
Translate each statement into an equation and solve the equation. Remember that to change a percent to a decimal, you divide the percent by 100, which is the same as moving the decimal point two places to the left. Also, a percent of a number means a percent times the number.
a. 20% of h is 140
20% * h = 140
0.2h = 140
Divide both sides by 0.2
h = 700
b. 5% of j is 320
5% * j = 320
0.05j = 320
Divide both sides by 0.05
j = 6400
c. 30% of g is 15
30% * g = 15
0.3g = 15
Divide both sides by 0.3
g = 50

Q₂ is the median
The median is the middle value in the data set. If there is no exact middle value then it is the average of the 2 values either side of the middle
Q₂ = [tex]\frac{67+68}{2}[/tex] = 67.5
Q₁ is the lower quartile and is the middle value of the data to the left of the median
Q₁ = 54
Q₃ is the upper quartile and is the middle value of the data to the right of the median
Q₃ = 77
