Miranda and Jean are planning a trip together. They want to drive, but they're not sure whose car to take. Jean's car uses 5/12 gallons of gasoline to travel 12 1/2 miles. Miranda's car can go 20 5/7 miles on 5/7 gallons of gasoline. Whose car is more fuel efficient, and what is the car’s fuel efficiency in miles per gallon?
Answer:
most fuel efficient is Jean's car....it gets 30 miles per gallon
Step-by-step explanation:
Jean's car :
(12 1/2) / (5/12) =
(25/2) / (5/12) =
25/2 * 12/5 =
150/5 =
30 miles per gallon
Miranda's car :
(20 5/7) / (5/7) =
(145/7) / (5/7) =
145/7 * 7/5 =
145/5 =
29 miles per gallon
what's 1/8 plus 5/12 as a common denominator simplified

Answer: The triangles' corresponding angles are congruent, and their corresponding sides are proportional; therefore, the triangles are similar.
Step-by-step explanation:
If all the corresponding sides and angles of two triangles are congruent then, the two triangles are said to be congruent..
If the corresponding angles of two triangles are congruent and their corresponding sides are proportional then triangles are similar (not congruent).
Complete statement: The triangles' corresponding angles are congruent, and their corresponding sides are proportional; therefore, the triangles are similar.

A line passes through the point (8,-1) and has a slope of -3/2
Answer:
y = -3/2 x +11Step-by-step explanation:
[tex](8,-1) = (x_1,y_1)\\\\m = -\frac{3}{2}[/tex]
Substitute values into point-slope form
[tex]y-y_1=m(x-x_1)\\\\y -(-1)=-\frac{3}{2} (x -8)\\\\y+1 = -\frac{3}{2}x+12\\\\y = -\frac{3}{2}x +12-1\\\\y =-\frac{3}{2}x +11[/tex]
The equation of line passes through the point (8, -1) will be;
⇒ y = - 3/2x + 11
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The point on the line are (8, - 1).
And, The slope of the line is,
⇒ m = - 3/2
Now,
Since, The equation of line passes through the point (8, -1).
And, Slope of the line is,
⇒ m = - 3/2
Thus, The equation of line with slope - 3/2 is,
⇒ y - (-1) = - 3/2 (x - 8)
⇒ y + 1 = - 3/2 (x - 8)
⇒ y + 1 = - 3/2x + 12
⇒ y = - 3/2x + 12 - 1
⇒ y = - 3/2x + 11
Therefore, The equation of line passes through the point (8, -1) with slope - 3/2 is,
⇒ y = - 3/2x + 11

Answer:
Step-by-step explanation:
"A rectangular room measures 3.8 meters in length and 4.9 meters in width. Jana multiplies both numbers together. Which expression would be best for her to use to check the reasonableness of her decimal multiplication?"
given that
the length is 3.8m long and,
width is 4.9m wide
The expression for the area is
Area= length * width
Area= 3.8*4.9
Area= 18.62 m^2
Therefore the expression best for her to use to check the reasonableness of her decimal multiplication is the area which is 18.62 m^2

I am really confused on how to do this.
Step-by-step explanation:
Ok, so in a standard equation, there can’t be any fractions, so you would have to multiply everything by 3, making the equation 3y+3=2(x-8) (p.s. don’t multiply the parentheses, leave the numbers in them alone for now). Then, you would go through with the equation process: 3y+3=2x-16. You move the 3 over to the right to make 3y=2x-19. Move the x to the left, -2x+3y=-19. But, there is a problem. The first term of this equation can’t be negative(yes, in standard form, x has to come first). So, you have to multiply everything by -1, resulting in the answer 2x-3y=19. I hope this helps!(The format for a standard form equation is: Ax+By=C).

What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
Tristan and two of his friends purchased tickets to a school play. Tristan paid for all the tickets with a $50.00 bill and received $23.00 in change.
Then the cost of the ticket will be
Cost = ($50 - $23) / 2
Cost = $27
If Tristan used a coupon for 25% off. Then the original price for all tickets will be
Original cost = $27 / 0.75
Original cost = $36
Then the cost of each ticket will be
Cost of each ticket = $36 / 2
Cost of each ticket = $18

4x+2=4 if x satisfies the equation above, what is the value of 2x+1
Answer:
2
Step-by-step explanation:
4x + 2 =4 => 4x = 2 => x = 0,5
if x =0,5 => 2x + 1 = 0,5.2 + 1 = 2
The values of "2x+1" will be "2".
The expression,
→ [tex]4x+2=4[/tex]
By subtracting "2" from both sides, we get
→ [tex]4x+2-2=4-2[/tex]
→ [tex]4x=2[/tex]
→ [tex]x = \frac{2}{4}[/tex]
→ [tex]x = 0.5[/tex]
By putting the value of "x" in the expression "2x+1", we get
→ [tex]2x+1 = 2(0.5)+1[/tex]
→ [tex]= 1+1[/tex]
→ [tex]= 2[/tex]

Suppose that you decide to buy a car for $57,000, including taxes and license fees. You saved $10,000 for a down payment. The dealer is offering you a choice between two incentives. Incentive A is $5000 off the price of the car, followed by a four-year loan at 6.06%. Incentive B does not have a cash rebate, but provides free financing (no interest) over four years. What is the difference in monthly payments between the two offers? Which incentive is the better deal? Use PMT= P r n 1−1+ r n−nt. The difference in monthly payments between the two offers is $nothing. (Round to the nearest cent as needed.)
Answer:
Following are the solution to this question:
Step-by-step explanation:
For incentive A
The car value = 57000
Calculating debt[tex]= 57000 - 10000[/tex]
[tex]= 47000[/tex]
Calculating the debt value after incentive [tex]= 47000 - 5000[/tex]
[tex]= 42000[/tex]
[tex]PMT = \frac{P(\frac{r}{n})}{(1 - (1 + (\frac{r}{n}))^(-nt))}[/tex]
[tex]= \frac{42000 \times (\frac{6.06 \%}{12})}{(1-(1+(\frac{6.06 \%}{12}))^{(-12 \times 4)})}[/tex]
[tex]= \frac{42000 \times (0.00505)}{(1-(1+(0.00505))^{(-48)})}\\\\= \frac{212.1}{(1-(1+(0.00505))^{(-48)})}\\\\=\frac{212.1}{-1.74}\\\\= - 121.89 \ \ or \ \ 121.89[/tex]
For incentive B
The car value = 57000
Calculating the debt value [tex]= 57000 - 10000[/tex]
[tex]= 47000[/tex]
Calculating the monthly payment =[tex]\frac{47000}{(12*4)}[/tex]
[tex]= \frac{47000}{(48)}\\\\= \frac{47000}{(48)}\\\\=979.166[/tex]
difference:
