Step-by-step explanation:
A gas station sells 1600 gallons of gasoline per hour if it charges $ 2.70 per gallon but only 900 gallons per hour if it charges $ 2.95
per gallon. Assuming a linear model
(a) How many gallons would be sold per hour of the price is $ 2.90 per gallon?
Answer:
(b) What must the gasoline price be in order to sell 1300 gallons per hour?
Answer:
Answer:
Look just at finding the linear model. Two points. Use price per gallon for x and gallons per hour sold for y. Your two points (x,y) are (2.15,1600) and (2.55,800).
Slope m=%281600-800%29%2F%280.15-0.55%29
m=800%2F0.40
m=2000
Using point-slope form for a line, and the lower-y point,
y-800=2000%28x-2.55%29
highlight%28y=2000%28x-2.55%29%2B800%29
Write an expression to show k less than 10
Step-by-step explanation:
"Write an expression to show k less than 10"
"less than" means that the number is being subtracted from a different number.
This means that "10" is being subtracted from "k"
Thus,
k - 10 is the appropriate expression for the statement, "k less than 10"
ANSWER: k - 10
answer and show work and ill give brainliest, Steven has one bag that contains three table-tennis balls numbered 1, 2, and 3. He also has a second bag that contains four table-tennis balls lettered A, B, C, and D.
Answer:
B
Step-by-step explanation:
Assuming Part A is the situation where the bags aren't merged, the probability of drawing a "1" followed by a "B" is (1/3)(1/4) or 1/12. This is because you have a 1/3 chance of getting a "1" and a 1/4 chance of getting a "B".
Now if we merge the bags, we have a 1/7 chance of getting a "1". We then have a 1/6 chance of getting a "B". This is because after we complete the first draw, the bag only has 6 remaining not 7. This gives us a probability of (1/7)(1/6) or 1/42.
So we know the probability will change so C is wrong. In both scenarios, we draw two balls anyways so A is wrong.
This leaves B, which is supported by the reasoning presented above.

the distance between two cities on a map is 3.5 centimeters. The map uses a scale in which 1 centimeter reprecents 20 kilometers. what is the actual distance between these two cities in kilometers?
Answer:
70 kilometers
Step-by-step explanation:
Set up a proportion where x is the actual distance
[tex]\frac{1}{20}[/tex] = [tex]\frac{3.5}{x}[/tex]
Cross multiply:
x = (20)(3.5)
x = 70
So, the actual distance is 70 km
The net of a rectangular prism and its dimensions are shown in the
diagram.What is the total surface area of the rectangular prism in square
inches?
PLEASE
Answer:
286.5 in.²
Step-by-step explanation:
The surface area of the prism = sum of the area of each surface
= (7.5*3) + (11.5*3) + (7.5*3) + (11.5*3) + (11.5*7.5) + (11.5*7.5)
= 22.5 + 34.5 + 22.5 + 34.5 + 86.25 + 86.25
Surface area = 286.5 in.²

Answer:
Step-by-step explanation:
The sum of adjacent angles traversed by a line must equal 180 degrees.
128+x=180
x=52
Answer:
x=52 degrees
Step-by-step explanation:
x=180-128=52 degrees because x is supplementary to 128 degrees.

Answer:
BD=13
(This must not be drawn to scale)
Step-by-step explanation:
You have to use the Angle Bisector Theorem to get a ratio.
12/x=27/(x+5)
cross multiply
12(x+5)=27x
12x+60=27x

There are formulas to solve cubics, but that probably is not the way you are expected to go. Here is a trial and error approach that works in this case.
Assume that the cubic can be factored and that the roots are r1, r2, and r3. Then the factored form is
(x-r1)(x-r2)(x-r3)=0
This shows that the constant must equal the product of the roots.
(r1)(r2)(r3)=-33
One possibility is that the roots are integers. In this case, a factor of 33 might work. Prime factorization of 33 gives 3 and 11. Try 3. Then (x-3) is a factor.
Divide the cubic by (x-3). It works. the result is
x^2+12x+11
This has factors of (x+11) and (x+1). Therefore, the roots are 3, -1, and -11

In 1985, there were 20 students
In 2005, there were 45 students
This is a change of 45-20 = 25 students.
This amount of change is divided by the original amount 20 to get 25/20 = 1.25 and converts to 125% when you move the decimal point 2 spots to the right.
-------------
If you want, you can use the formula below
x = old value = 20
y = new value = 45
z = percent change
z = [ (y-x)/x ] * 100%
z = [ (45-20)/20 ] * 100%
z = (25/20) * 100%
z = 1.25*100%
z = 125%
The z value being positive means we have a percent increase.
It's possible to have over 100% increase since 100% of 20 is 20. Having a 100% increase means we increased by 20. Since we increased by more than 20, this means the increase must be over 100%.

I) Substitute equation to find the area
a = hb (area = height x base)
a = 2.5(5.5)
II) Solve:
a = 2.5(5.5)
a = 13.75
The area is 13.75 ft^2.

Answer:
these are the equivalwnt expressions 4/5×15=4×5/15; 5×3=3×15/5
The expression equivalent to 4/5 × 15 is 4×3
What is the BODMAS rule?According to the BODMAS rule, the brackets have to be solved first followed by powers or roots (i.e. of), then Division, Multiplication, Addition, and at the end Subtraction. Solving any expression is considered correct only if the BODMAS rule or the PEMDAS rule is followed to solve it.
Given here the expression 4/5×15 thus simplifying it we get
4/5×15= 4×3
= 12
Hence, The expression equivalent to 4/5 × 15 is 4×3

Dan invests £18790 into his bank account. He receives 5,3% per year simple
interest. How much will Dan have after 7 years? Give your answer to the nearest
penny where appropriate,
Answer:
697109 pennies
Step-by-step explanation:
First, you use the formula A = P (1 + rt).
R= rate which is 5.3%
T= time which is 7 years.
P is the principle which is 18790
A= is the answer
so first you multiply 7*5.3% which you get 0.371
then you multiply that with 18790 which then you get 6971.09
if you want pennies you multiply it with 100 to get 697109

Answer:
$76.32
Step-by-step explanation:
First, add up all the costs for everything:
17 + 30 + 25 = 72
Now, we need to add the sales tax. To do this we multiply 72 by 1.06. This is because the sales tax is 6% (the decimal form of 6% is 0.06), and we add it on to the 100% cost (which is 1 in decimal form).
(72)(1.06) = 76.32
Therefore the total cost of everything Walter bought plus the tax rate is $76.32.
I hope this helps!!
