Olivia takes a trip to visit her aunt who lives 120 mi. away. Olivia's car can travel 24 miles per gallon of gasoline. If gasoline costs 03 per gallon, how much will Olivia pay for the gasoline for this trip? Show or explain your reasoning.
Answer:
$15
Step-by-step explanation:
Given that :
Aunt's distance = 120 miles
Miles per gallon of Olivia's car = 24 miles per gallon
Cost of gasoline = 3 per gallon
Cost of gasoline for the trip :
(Aunt's distance / miles per gallon) * cost of gasoline per gallon
(120 miles / 24 miles per gallon) * 3
5 * 3 = $15
Cost of gasoline for the trip = $15

Answer: Choice H (upper right corner)
====================================================
Explanation:
Refer to the diagram below.
I started with the set of five circles you were given. Then I cut each of them in half. This results in 2*5 = 10 sections (each section is numbered in blue). If you shade 9 of those 10 sections, then you'll represent the fraction 9/10. This is what choice H represents, so that's why it's the answer
9/10 = 0.90 in decimal form
0.90 = 90% in percent form

The Reiter family uses three different-sized scoops to serve mashed potatoes : blobs, globs and gobs (these names are so weird aren't they). 2 blobs are equal to 1 glob, and 5 globs equal 3 gobs of mashed potatoes. A bowl holds 12 gobs of potatoes. How many blobs are there in the bowl? RATIO PROBLEM!!! DUH, DUH, DUHHHHHHH.
Answer: 30 blobs
Step-by-step explanation:
The ratios are:
2 blobs: 1 glob
5 globs: 3 gobs
If the bowl can hold 12 gobs, then we can multiply the 5:3 ratio by 4, to make solving easier. We get the ratio 15:12 and then we need to multiply the 2:1 ratio by 15 to get the answer 30 blobs

West direction. What is the distance Bubly has to cover to reach Bunty?
the ans is:700km
plz explain me
Answer:
700 km
Step-by-step explanation:
Distance covered by Bunty = 500 km
Distance covered by Bubbly = 200 km
Displacement between them = 500 + 200 km = 700 km
This means Bubbly has to cover a distance of 700 km to reach Bunty.

y = -f(x) – 3 describes the graphed function.
When f is negative it is reflected over the x-axis.
-3 means to translate 3 units down.

Answer:
(-1,-2)
Step-by-step explanation:
D's original postion/location is at (1,-2)
You basically take the point D and keep your y coordinate, -2, the same /constant and change your x coordinate (flip the sign)
So keeping the y-coordinate constant, -2 changing positive 1 to negative 1
So.. D's location reflected on the y axis is (-1,-2)
*Let's Say: D was reflected on the x-axis you would do the opposite by keeping the x coordinate constant and flipping the y-coordinate sign (to positive)
So...
D's location reflected on the x-axis is (1,2)

how to solve using Substitution or Elimination?
y=3x-1
y=2x+2
By elimination:
y = 3x - 1
y = 2x + 2
Subtract the second equation from the first
0 = x - 1
y = 2x + 2
Subtract the first equation from the second
0 = x - 1
y = x + 3
Subtract the first equation from the second again
0 = x - 1
y = 4
Subtract x from both sides of the first equation
- x = - 1
y = 4
Divide the first equation by (-1)
x = 1
y = 4
So, the solution is x = 1 and y = 4 {or: (1, 4)}Harriet Cutter’s gross pay for this week is $555. She is single and claims 1 allowances. What amount will be withheld from Harriet’s pay for federal income tax?

Answer:
B. The student multiplied 380 by [tex]\frac{19}{20}[/tex].
Step-by-step explanation:
In the equation -[tex]\frac{3}{4}[/tex]y - [tex]\frac{1}{5}[/tex]y = 380, we can further evaluate the equation into:
-[tex]\frac{19}{20}[/tex]y = 380
To find y, we need to multiply 380 by the inverse of the fraction on the other side, which is -[tex]\frac{20}{19}[/tex]. However, the students multiplied 380 by [tex]\frac{19}{20}[/tex] to get 361. Thus, this was the mistake.

1. Greg bought a huge Christmas tree. He had to pay a
25% advance to reserve the tree. How much did he pay
to reserve the tree if the cost of the tree is $300?
Answer:
Answer: $1,200
Step-by-step explanation:
Since multiplying 25% would take off 25% from 300, do the opposite (aka divide .25 from 300).
300/.25 = 1,200
A plumber charges his customers $25.70 per hour, h, plus a $54.50 service fee.On Tuesday,he earns $118.75 for fixing Mrs.Goodwill's sink. How long does it take the plumber to fix Mrs.Goodwill's sink
Answer:
2.5 hours
Step-by-step explanation:
Given that :
Charge per hour = 25.70
Service fee = $54.50
If total earning = 118.75 ; how many hours did it take to fix the sink?
Let number of hours = x
Total earning = service fee + (charge per hour * number of hours)
118.75 = $54.50 + (25.70x)
118.75 - 54.50 = 25.70x
64.25 = 25.70x
x = 64.25 / 25.70
x = 2.5
Hence, it took 2.5 hours to fix the sink
