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.
Answers
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

can someone please help me factor and write the equations for these two problems ?
Answers
Answer:
Step-by-step explanation:
Asymptotes 3
g(x) = [tex]\frac{3x}{x^2-3x-10}[/tex]
Factors of denominator will be,
x² - 3x - 10 = x² - 5x + 2x - 10
= x(x - 5) + 2(x - 5)
= (x + 2)(x - 5)
Therefore, factored form of g(x) will be,
g(x) = [tex]\frac{3x}{(x + 2)(x - 5)}[/tex]
Asymptotes 4
h(x) = [tex]\frac{(x-5)}{x^{2} + 14x + 40}[/tex]
= [tex]\frac{x-5}{x^{2}+10x+4x+40}[/tex]
= [tex]\frac{x-5}{x(x+10)+4(x+10)}[/tex]
= [tex]\frac{x-5}{(x+10)(x+4)}[/tex]

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.
Answers
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

Answers
Answer:
y=-f(x)-3
Step-by-step explanation:
when f is negative it is reflected over the x-axis and -3 means to translate 3 units down
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)

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.
