Car A travels 18 miles every 20 minutes. Car B travels 13 miles every 12 minutes. Which statement best compares how far the two cars can travel in an hour?
Answer:
The answer is C) car b travels 11 more miles than car a in one hour
Step-by-step explanation:
Car A: 18/20(60)=54 mph
Car B: 13/12(60) = 65 mph
So car b travels 11 more miles than car a in one hour
Which expression has a greater value, 3/8 x 5:6 or 3/8 divided by 5/6? Explain
Answer:
3/8 divided by 5/6
Step-by-step explanation:
To divide a fraction by a fraction, you multiply the first fraction by the reciprocal (aka the fraction flipped upside down, in this case the reciprocal of 5/6 is 6/5). Since 6/5 is greater than 5/6, 3/8 divided by 5/6 is greater than 3/8 times 5/6.
Answer:
[tex]\frac{3}{8}[/tex] ÷ [tex]\frac{5}{6}[/tex]

Answer:
5.66
Step-by-step explanation:
This is a 45 – 45 – 90 triangle. What this means is that the two legs are both congruent and the hypotenuse is the length of the legs times [tex]\sqrt{2}[/tex].
So in order to find this, we have to divide 8 by the square root of 2.
Putting this in to a calculator, we get 5.6568542. When rounded to the nearest hundredth, it is 5.66, which is the first answer.

Find
Sin 2 (30degrees)
Answer:
Sin 2 (30)°= [tex]\frac{\sqrt{3} }{2}[/tex]
Step-by-step explanation:
Explanation:-
Given that Sin 2 (30)°
we know that the formula sin2θ = 2sinθ cosθ
Given that θ = 30°
Now
sin2(30)° = 2sin30° cos30°
[tex]= 2 ( \frac{1}{2} X \frac{\sqrt{3} }{2} )[/tex]
After cancellation, we get
Sin 2 (30)° = [tex]\frac{\sqrt{3} }{2}[/tex]
Final answer:-
Sin 2 (30)° = [tex]\frac{\sqrt{3} }{2}[/tex]

If a quadrilateral has these known angle degrees: 35, 35 and 145, what are the degrees of the fourth angle?
Answer:
145
Step-by-step explanation:
The total sum of all the angles is 360 degrees. If we add up 35, 35, and 145 we get 215. 360-215=145.
If an x-coordinate repeats, can a relation still be a function?
I need help right now
Answer:
No
Step-by-step explanation:
if you see any duplicates or repetitions in the x-values, the relation is not a function.
Given the following table of values for f(x), find f(2).
x −1 0 1 2 3 9
f(x) 5 10 8 5 7 14
The value of the function at x = 2 will be 5.
What is a function?A function is a statement, tenet, or rule that establishes a connection between two variables. Mathematics is replete with functions, which are necessary for the construction of intricate relationships.
The result of the calculation that the mathematical model depicts is the expression's result when the necessary parameters and natural laws are given values.
The table represents a function.
x f(x)
-1 5
0 10
2 8
9 14
In the above table, we can see that at the value of x = 2 in the function the value of the whole function is 5.

Residents in a city are charged for water usage every three months. The water bill is computed from a common fee, along with the amount of water the customers use. The last water bills for 40 neighborhood residents are displayed in the histogram below.
A histogram titled Neighborhood Monthly water bill has monthly water bill (dollars) on the x-axis and frequency on the y-axis. 100 to 125, 1; 125 to 150, 2; 150 to 175, 5; 175 to 200, 10; 200 to 225, 13; 225 to 250, 8.
Which interval contains the median water bill?
$150–$175
$175–$200
$200–$225
$225–$250
The interval which contains the median water bill is $200 - $225
The tabulated data :
Class interval ____ Frequency ___ Cummulative frequency
100 to 125, ________ 1 ___________ 1
125 to 150, 2 ______ 2 ___________3
150 to 175, 5 _______5 ___________8
175 to 200, 10 ______10 __________18
200 to 225, 13 _____13 __________ 31
225 to 250, _______ 8 __________40
The median class = Cummulative frequency / 2
The median class = 40 / 2
The class interval which contains the 20th frequency.
This is the 200 - 225 class
The interval which contains the median water bill is $200 - $225

A merry go around has a radius of 18 ft. If a passenger gets on a horse located at the edge of the wheel and travels 38ft, find the angle of rotation to the nearest degree
Answer:
121 degrees
Step-by-step explanation:
Given
Radius r = 18ft
Length of the arc = 38ft
Required
angle of rotation
Using the formula
Length of an arc = theta/360 * 2πr
Substitute the given data
38 = theta/360 * 2π(18)
38 = theta/360 * 113.04
theta/360 = 38/113.04
theta/360 = 0.33616
theta = 0.33616 * 360
theta = 121.02
Hence the angle of rotation to the nearest degree is 121 degrees

Bianca bought a pack of rechargeable batteries for
$9.99. If the sales tax on the batteries is 3% and Bianca
pays with $11 cash, how much change will she get back?
Answer:
$0.71
Step-by-step explanation:
9.99 + (3% of 9.99) = 10.2897
11 - 10.2897 = 0.7103, so $0.7103 is our answer. However, this isn't a real amount of money that can be handed from a clerk to a customer. So, we will round it to the nearest cent, bringing us to $0.71, our final answer.

A swimming team from East High School is participating in a swim meet with, with three swimmers competing in the
butterfly stroke race.
There are 15 total swimmers competing in the butterfly stroke race.
What is the probability that two East High School swimmers finish first and second in the race?
Enter your answer as a simplified fraction.
Answer:
1/35
Step-by-step explanation:
P= 6 *13! / 15! = 1/35
The probability of two east high school swimmers to come first and second is 1/35.
How to calculate probability?
First, let us calculate the number of desired outcomes:
The first position has 3 possibilities and 2nd position has 2 possibilities and 3rd position has 13 possibilities (leaving people of 1st and 2nd position).
Total=2.3.13
Now, calculate the total outcome:
1st position has 15 possibilities, 2nd has 14 and 3rd has 13.
Total=15.14.13
Probability=desired outcome/total outcome
=2.3.13/15.14.13
=1/35
Therefore, probability of the given situation is 1/35.
