The sum of two positive integers is 12. When the smaller integer is subtracted from five times the larger, the result is 36. Find the two integers.
Answer:
The smaller integer is 4 and larger integer is 8 .
Step-by-step explanation:
First we have to form own variables and expression. So we let the smaller integer be x and the larger integer be y. Next using the information given to form expressions :
[tex]x + y = 12 \\ 5y - x = 36[/tex]
Lastly, we can solve the simultaneous equation using Elimination :
[tex]x + y = 12 - - - (1)[/tex]
[tex] - x + 5y = 36 - - - (2)[/tex]
[tex](1) + (2)[/tex]
[tex]x + ( - x) + y + 5y = 12 + 36[/tex]
[tex]6y = 48[/tex]
[tex]y = 8[/tex]
[tex]sub \: y = 8 \: into \: (1)[/tex]
[tex]x + 8 = 12[/tex]
[tex]x = 4[/tex]
If your car gets 22 miles per gallon, how much does it cost to drive 360 miles when gasoline costs $2.80 per gallon?
Answer:
45.6
Step-by-step explanation:
the way you find this would be
22/360 = 16.32.80 x 16.3 = 45.64But to get 45.6 you would have to round this answer to the nearest tenth 45.64 rounded to the nearest tenth would be 45.6Therefore your answer would be $45.6 per gallon14. Which set of data is qualitative?

"Suppose that 5% of bags contain forbidden items."
Forbidden
0.05
Not forbidden
What is the probability that a randomly chosen bag does NOT contain a
forbidden item?
P(not forbidden) =
Answer:
.95 is the correct answer. See screenshot below
Step-by-step explanation:
The probability that a randomly chosen bag does NOT contain a forbidden item is 0.95
What is probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.
Given that, 5% of bags contain forbidden items.
We know that, the probability of an event not happening is 1 minus the probability of the event happening,
Therefore, the probability that a randomly chosen bag does NOT contain a forbidden item = 1-0.05 = 0.95
Hence, the probability that a randomly chosen bag does NOT contain a forbidden item is 0.95

A cylinder has a radius of 14 m and a height of 6 m. What is the exact volume of the cylinder? 84π m³ 168π m³ 504π m³ 1176π m³
Answer:
1176π m³
Step-by-step explanation:
The formula for the volume of a cylinder is:
V = πr²h
Let's substitute the values given into this equation:
V = πr²h
V = (π)(14²)(6)
Solve:
V = (π)(14²)(6)
V = (π)(196)(6)
V = 1,176π
Therefore, the volume of the cylinder is 1176π cubic meters.
Answer:
1176
Step-by-step explanation:
r (radius) = 14 m
h (height) = 6 m
v (volume) = ?
Formula: V=πr2h
We are looking for the volume of the cylinder. We know that the Radius is 14 and the height is 6.
So we need to
1: Radius * 14 * 6
2: Radius * 196* 6
Answer: 1176

1/3
1/4
Answer:
there are 12 sections in total and 3 green sections
3 wanted sections /12 total sections = 1/4 chance to get green
hope this helps
Step-by-step explanation:
Probability of spinning green on the spinner is equals to [tex]\frac{1}{4}[/tex] .
What is probability?" Probability is defined as the mathematical statement which represents the ratio of number of favourable outcomes to the total number of outcomes."
Formula used
Probability = [tex]\frac{Number of favourable outcomes}{Total number of outcomes}[/tex]
According to the question,
Total number of spinning colour in a spinner = 12
Number of green spinner = 3
Substitute the value in the formula to get the probability we get,
Probability of spinning green = [tex]\frac{3}{12}[/tex]
= [tex]\frac{1}{4}[/tex]
Hence, probability of spinning green on the spinner is equals to [tex]\frac{1}{4}[/tex] .

Sam is eating a Big Hamburger. The first bite was 20% of the Hamburger, the second bite was 20% of what is left and so every next bite is 20% of what is left.
a) How much did the Hamburger weigh originally, if after the second bite there was 160g of it left?
Answer:
250g
Step-by-step explanation:
To calculate the original weight, you just have to find how much was left of the hamburger after the second bite.
Say that the hamburger is x grams.
0.64x = 160
x = 250

An item is priced at $13.42. If the sales tax is 4%, what does the item cost including sales tax? If necessary, round to the nearest cent
Answer:
Total cost = $13.96
Step-by-step explanation:
The total to be paid for the item is the addition of its price plus the taxes. That is:
[tex]Total\,\,cost=13.42+0.04\,*\,13.42\\Total\,\,cost=13.42+0.5368\\Total\,\,cost==13.9568[/tex]
Which can be rounded to $13.96
A new car sells for $27,500. The value of the car decreases by 14% annually. You want to sell the car when it's worth about $4000. Explain how many years you will keep the car, when you will sell it, and how you determined your answer.
Answer:
The formula would be:
27500 x (1 - 14/100)^year = 4000
=> (86/100)^year = 4000/27500
=> 0.86^year = 0.145
=> year = log(0.145)/log(0.86) = 12.8
Hope this helps!
:)
Answer:
13 years
Step-by-step explanation:
4000 = 27500 × (1 - 14/100)^t
4000 = 27500 × 0.86^t
0.86^t = 8/55
t ln(0.86) = ln(8/55)
t = 12.78248711
