The distance that a person drives at a constant speed varies directly with the amount of time they have been
driving. If, at a particular speed, a person drives 107 miles in two hours, then how far will they drive, at the
same speed, in 14 hours?
Answers
Answer:
749 miles
Step-by-step explanation:
I divided 107 by 2 and then multiplied that by 14
a person drives 53.5 at that particular speed so they keep driving that amount of miles each hour so it's 749
The distance they will drive, at the same speed, in 14 hours is 749 miles.
Given the following data:
Distance A = 107 milesTime A = 2 hoursTime B = 14 hoursTo find how far (distance) will they drive, at the same speed, in 14 hours, we would apply direct proportion:
By using direct proportion:
107 miles = 2 hours
X miles = 14 hours
Cross-multiplying, we have:
[tex]2X = 107 \times 14\\\\2X = 1498\\\\X = \frac{1498}{2}[/tex]
X = 749 miles

a party rental company has chairs and tables for rent. the total cost to rent three chairs and five tables is $52. The total cost to rent 9 chairs and 7 tables is$86. what is the cost to rent each chair and each table?
Answers
Answer:
The cost for 1 chair is $2.75 and the cost for 1 table is $8.75.
Step-by-step explanation:
Use the elimination method of linear equations to find your answer.
Our equations for this problem are:
3c+5t=52 and 9c+7t=86
Multiply the entire first equation by -3.
-3(3c+5t=52)
Simplify the equation from above:
-9c-15t=-156
Stack the two equations on top of each other and add/subtract:
-9c-15t=-156
9c+7t=86
You should be left with -8t=-70. Simplify this to find the value of t:
t=8.75
Plug the value of t into any of the original equations and solve for c.
3c+5(8.75)=52
Simplify the equation above:
3c+43.75=52
Subtract 43.75 from both sides of the equation:
3c=8.25
Divide both sides by 3 to get your c value:
c=2.75

the value of y is 20% more than the value of x. the ratio of x:y = 5
Answers
Answer:
x:y = 5:6
Step-by-step explanation:
y = x(20/100) + x
y = x (1/5) + x
Factorize X
y = x (1/5 + 1)
y = x (6/5)
5y = 6x
-----------------------------
ratio x:y = 5:6
The ratio is x:y = 5:6.
What is ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same sort and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is expressed as a: b.
Given:
value of y is 20% more than the value of x
So,
y = x(20/100) + x
y = x (1/5) + x
y = x (1/5 + 1)
y = x (6/5)
5y = 6x
Hence, the ratio is x:y = 5:6.

Use the formula for simple interest to find the interest rate if a deposit of $1400 earned $490 of interest after 5 years,
Answers
I = P•R•T
where:
I = interest
P = principal
R = interest rate
T = time (in years)
We can isolate R algebraically to find out the interest rate:
I = P•R•T
Divide both sides by P•T:
I / (P•T) = (P•R•T)/(P•T)
The formula for the interest rate is:
R = I / (P•T)
Substitute the given values into this formula to solve for the interest rate (R):
R = I / (P•T)
R = $490/ ($1,400 • 5 years)
R = $490 / $7,000
R = 0.07 or 7%
Therefore, the interest rate is 7%.

For f(x) = px +q and g(x) =
X-9), p70, find (fog)(x) and (g of)(x). Then determine whether (fog)(x) = (gof)(x).
Answers
Answer: f(x) = 2x
g(x) = x + 3
First let us find (fog)(x)
(fog)(x) = f(g(x)
= f(x+3)
= 2(x+3)
= 2x + 6
==> (fog)(x) = 2x + 6
Now let us find (gof)(x):
(gof)(x) = g(f(x)
= g(2x)
= 2x + 3
==> (gof)(x) = 2x + 3
