Answer:
2 miles per hour
Step-by-step explanation:
We use the distance formula. D = r * t
45/3 = 15 mph | Trip 1 |
44/4= 11mph | Trip 2 |
15-11 = 4 mph difference traveling upstream or downstream. Thus the speed of the current is 2 miles per hour.
Which relation is also a function?
The answer is A
I put D bc someone said it was D and i got it wrong and it showed the answer was A so yeah ;-;

Answer:
(f o g) = -5x+22
Step-by-step explanation:
f o g basically means f(g(x))
So:
f(g(x)) = -5(x-4)+2
f(g(x)) = -5x+20+2
f(g(x)) = -5x+22
Therefore: (f o g) = -5x+22
This is called function composition. Basically, the output of g(x) goes into the input of f(x).

A scientist studied the migration patterns of two types of whales. The humpback whale traveled 2,000 miles in 25 days. The gray whale traveled 2,250 miles in 30 days. Assuming the humpback whale travels the same distance each day, what is the unit rate for the humpback whale in miles per day?
Answer:
it is 80 miles
Step-by-step explanation:
2000 divided by 25 is 80 therefore you multiply 80 x 30

Inspectors for a hospital chain with multiple locations randomly select some of their locations for a cleanliness check of their operating rooms. The inspectors check every operating room in the hospitals that were chosen. What sampling method was used?
Answer:
Cluster Random Sample
Step-by-step explanation:
The operating rooms were divided into (hospital locations) and inspectors sampled every operating room from some of the groups.
Sampling method is the method where the subset of an overall population is selected.
The sampling method used was cluster sampling
From the question, we understand that:
The inspectors select some locationsThen all selected locations was checkedThe above illustrates cluster sampling.
This is so because, cluster sampling involves breaking down a population into smaller size.
In this case, the smaller size are the locations that were selected.

The price of a car has been reduced from $22,500 to $16,650. What is the percentage decrease of the price of the car?
Answer:
26%
Step-by-step explanation:
$22,500-$16,650= $5,850
I started by multiplying buy 0.20 from $22,500 and then Jumped to 0.25% and when I realized i was close I multiplied $22,500 *0.26 and matched the decreasing price of $5,850.
$22,500*0.20 = $4,500 off
$22,500*0.25 = $5,625 off
$22,500*0.26 = $5,850 off

The Quik-Clean Car Wash charges $15 for a car wash plus $2.50 per gallon for unleaded gasoline. The Mighty Clean Car Wash charges $10 for a carwash plus $2.75 per gallon for unleaded gasoline. Josh is comparing the cost of having his car wash plus filling up his tank with gas at each business. How many gallons of gas would he need to purchase for the cost to be the same at each car wash?
Answer:
Josh would need to purchase 20 gallons of gas for the cost to be the same at each car wash
Step-by-step explanation:
We need to model both car wash's costs. The Quik-Clean Car Wash charges $15 for a car wash plus $2.50 per gallon for unleaded gasoline. If x is the number of gallons of unleaded gasoline. the total charges of this store are:
C1=15+2.5*x
The Mighty Clean Car Wash charges $10 for a carwash plus $2.75 per gallon for unleaded gasoline. Following the same procedure, their costs are:
C2=10+2.75*x
Josh wants to know how many gallons of gas will make both businesses charge the same. Equating both equations:
15+2.5*x=10+2.75*x
Simplifying:
-0.25x=-5
Solving:
x=-5/(-0.25)=20
Josh would need to purchase 20 gallons of gas for the cost to be the same at each car wash
Hannah wants to buy a $540 camera. She can save $40 each week from her paycheck. However, before Hannah can buy the camera, she must give her brother $60 that she owes him. For how many weeks will Hannah need to save before she can pay back her brother and buy the camera?
Answer:
w = 12
Step-by-step explanation:
Create formula:
540 = 40w - 60 where 540 is the cost of the camera, 40 is the amount saved, w is the number of weeks, 60 is the amount owed
Solve for w
540 = 40w - 60: subtract 60
480 = 40w: divide by 40
w = 12

At the beginning of the business day, a bank's vault held $575,900. By the end of the day, $(3.5 103) had been added to the vault. How much money did the banks vault hold at the end of the business day write ur answer in standard form
3.5*10^3=3,500
3,500+ 575,900=579,400
The bank vault will hold $575,900 + $3.5 x 10^3 = $579,400 at the end of the business day.
What are integers?An integer is a number with no decimal or fractional part and it includes negative and positive numbers, including zero.
Now it is given that,
Money in the bank vault at the beginning of the day = $575,900
Money added in the vault at the end of the day = $3.5 x 10^3 = $3,500
Since money is added in the vault thus it is gain.
So, Money added in the vault at the end of the day = + $3,500
Thus, Money at the end of the business day = $575,900 + $3,500 = $579,400
Thus, the bank vault will hold $575,900 + $3.5 x 10^3 = $579,400 at the end of the business day.

reduce [tex]\frac{54}{81}[/tex]
Answer:
[tex]\text{The reduced fraction is } \frac{2}{3}[/tex]
Step-by-step explanation:
Fraction Reduction
To reduce a fraction, we try to divide both the numerator and denominator by the very same number until no more numbers can be found.
The fraction to reduce is:
[tex]\displaystyle \frac{54}{81}[/tex]
Since the denominator is odd, we cannot divide by 2, but we can divide by 3:
[tex]\displaystyle \frac{54}{81}=\frac{18}{27}[/tex]
We divide by 3 again:
[tex]\displaystyle \frac{18}{27}=\frac{6}{9}[/tex]
We divide by 3 one last time:
[tex]\displaystyle \frac{6}{9}=\frac{2}{3}[/tex]
[tex]\text{The reduced fraction is } \frac{2}{3}[/tex]
Convert the fraction into a decimal by dividing

Find two consecutive odd numbers such that the sum of the larger number and twice the smaller number is 27 less then foir times the smaller number
Answer:
29 and 31Step-by-step explanation:
x - some integer
2x+1 - an odd integer (the smaller one)
2x+1+2=2x+3 - the next odd integer consecutive to 2x+1 (the larger)
2×(2x+1) - twice the smaller number
2x+3+2•(2x+1) -the sum of the larger number and twice the smaller number
4•(2x+1) - four times the smaller number
4•(2x+1)-27 - 27 less then four times the smaller number
2x + 3 + 2•(2x + 1) = 4•(2x + 1) - 27
2x + 3 + 4x + 2 = 8x + 4 - 27
6x + 5 = 8x - 23
-5 -5
6x = 8x - 28
-8x -8x
-2x = - 28
÷(-2) ÷(-2)
x = 14
2x+1 = 2•14 + 1 = 29
2x+3 = 2•14 + 3 = 31
Check: 31+2•29=31+58=89; 4•29-27=116-27=89

Suppose that the volume of water in the rain barrel
decreased by 4 5/8 gallons in four minutes. What will be
the change in the volume of water after one minute?
Answer:
Step-by-step explanation:
A unit rate is a rate for one of something.
It is written as a ratio with a denominator of one.
The change in the volume of water in one minute is 1 5/32 gallons.
What is a unit rate?A unit rate is a rate for one of something.
It is written as a ratio with a denominator of one.
We have,
4 5/8 gallons decrease in 4 minutes.
This can be written as:
4 5/8 gallons = 4 minutes
37/8 gallons = 4 minutes
Dividing both sides by 4 we get,
(37/8) / 4 = 4/4 minutes
37/(8x4) = 1 minute
37/32 = 1 minute
1 5/32 gallons = 1 minute
Thus the change in the volume of water in one minute is 1 5/32 gallons.
