Bill cut a cake into 14 pieces and ate 3 of them. Carol cut a same size cake into 16
pieces and ate 5 of them who ate more?
How much cake did they eat altogether?
Answer:
Bill ate more.
Step-by-step explanation:
Bill 14/3=4.66
Carol 16/5=3.2
then multiply the answer by 100 to get the percentage of how much they ate. After you get that, you add it together to figure out the percentage of cake they ate together.

In how many different ways can a badminton team with 2 members, be chosen from a group of 6 people?
Answer:
15 ways
Step-by-step explanation:
We need 2 people from a group of 6.
Pick a random person from the 6, then group them with another person. We have 5 ways to do so.
Now, we will pick a person to group with the person who got grouped with the first person, except the first person themself. We have 4 ways to do so
Keep repeating, we will have 5 + 4 + 3 + 2 + 1 = 15 ways to choose 2 people out of 6.

Probability, help, please
Problem 1
Answer: Choice A) 1/3-------------------
Explanation:
The notation "P(tune-ups | AC repair)" is the same as saying "P(tune-ups given AC repair)".
The "given" means we only focus on the "AC repair" circle.
Add up the numbers in that circle to get: 1+3+2+0 = 6
There are 6 ASE certified mechanics that can do AC repair.
Of those 6 people, only 2+0 = 2 can do engine tune-ups. Note I added the values in the "AC repair" and "tune-ups" overlapped region.
Therefore, we get the probability 2/6 = 1/3
==========================================================
Problem 2
Answer: B) 2/3-------------------
Explanation:
First, we'll add the numbers found in either the "brakes" or "tune-ups" circles.
4+1+2+2+3+0 = 12
There are 12 mechanics that can handle brakes or tune-ups or both.
Now add up all of the numbers shown regardless of their location. We have 4+1+3+2+2+0+3+3 = 18 mechanics total.
So,
m = number who can do brakes or tune-ups or both
m = 12
n = number of mechanics total
n = 18
And,
P(brakes or tune-ups) = m/n
P(brakes or tune-ups) = 12/18
P(brakes or tune-ups) = (6*2)/(6*3)
P(brakes or tune-ups) = 2/3

the figure shows a circle within a square. Find the circumference of the circle let π = 3.14.
The side of the square = 16 in
When a circle is inscribed in a square, the length of each side of the square is equal to the diameter of the circle.
So, the diameter of the circle is equal to 16 in => radius = 8 in
Circumference = 2πr = 2π8 = 16π = 50.24
a cone and a cylinder with their dimensions are shown in the diagram

which measurement is the closest to the difference between the volumes of these figures in cubic inches?
A: 75 in.^3
B: 226 in.^3
C: 101 in.^3
D: 151 in.^3
The difference between the volumes of these figures is 25.1 in³
Volume
Volume is the amount of space occupied by a three dimensional object or figure.
The volume of a cone is given by:
Volume = (1/3) * π * radius² * height = (1/3) * π * (4²) * 12 = 201.1 in³
The volume of a cylinder is given by:
Volume = π * radius² * height = π * (3²) * 8 = 226.2 in³
The difference in volume = 226.2 - 201.1 = 25.1 in³
The difference between the volumes of these figures is 25.1 in³
Find out more on Volume at: https://brainly.com/question/1972490
Answer:
A. 75 inches
Step-by-step explanation:
Assuming that the attached picture is the question you are referring to, the answer is 75.
For the volume of the cone, [tex]\frac{1}{3}[/tex] of the bh = 16
For the cylinder, the volume is 48.
48 - 16 = 32
75 is the closest to 32 from all the options.
The value of r2 for a relationship between distance (in miles) and the cost (in dollars) of a shuttle bus from a hotel to
an airport is calculated using computer software. Identify and interpret the value of r2 by completing the sentence.
The value of r2=___ tells us that about___ of the variation in the ___ of the shuttle bus is accounted for by the linear relationship created with the ____ of the shuttle bus.
Answer:
96.80%
97%
cost
distance in miles
Step-by-step explanation:
The first number is given in the data, you have to round up the percentage for the second answer, and for the last two its given in the directions.
The complete statement is: the value of r2 = 96.80% tells us that about 97% of the variation in the cost of the shuttle bus is accounted for by the linear relationship created with the distance of the shuttle bus.
How to identify and interpret r^2From the table, we have the following parameter;
R-Sq = 96.80%
The above value represents the coefficient of determination, r^2.
So, we have:
r^2 = 96.80%
Approximate
r^2 = about 97%
From the question, the dependent variable (y) is cost, while the independent variable (x) is distance.
Since the coefficient of determination (r^2) measures the variation between the dependent and the independent variables, the blanks would be completed with 96.80%, 97%, cost and distance, in that order

The speed of light is approximately
1.86 x 10^5 miles per second. How
many miles will light travel in a
24-hour day?
Answer:
16,070,400,000 miles per day
Step-by-step explanation:
Starting off, there are 60 seconds in a minute and 60 minutes in an hour. In total, there are 3600 seconds in an hour. We still need to multiply that number by 24 because the question asks for a full day. 3,600 multiplied by 24 is 86,400. Now that we know there are 86,400 seconds in a day, we can finally get down and dirty.
1.86 × 10^5 × 8.64 × 10^4
Combine the two powers of ten and get
1.86 × 8.64 × 10^9
This will give you
16.0704 × 10^9 or 16,070,400,000

There is a spinner with 15 equal areas, numbered 1 through 15. If the spinner is spun one time, what is the probability that the result is a multiple of 5 and a multiple of 3?
Answer:
6.67%
Step-by-step explanation:
Find the amount of numbers that are multiples of 3 and 5
multiples of 3 = 3, 6, 9, 12, 15
multiples of 5 = 5, 10, 15
only 15 overlaps between these two groups, so it is one number
the total number of available numbers is 15
1/15 = 0.0667
multiply this by 100 to get a percentage
0.0667 * 100 = 6.67%

x = 3.133
Step-by-step explanation:
15x + 3 = 50
15x = 50 - 3
15x = 47
x = 47/15
x = 3.133
Hope it helps you!!Hello.
First, let's subtract 3 from both sides.
15x+3-3=50-3
15x=47
Now, in order to figure out what x equals, we need to divide both sides by 15:
[tex]\displaystyle\frac{15x}{15} =\frac{47}{15}[/tex]
[tex]x=\displaystyle\frac{47}{15}[/tex]

Simplify 81p6q2÷3p2q5 HELPPP
Answer:
[tex]\displaystyle \frac{81\, p^{6}\, q^{2}}{3\, p^{2} \, q^{5}} = \frac{27\, p^{4}}{q^{3}}[/tex].
Step-by-step explanation:
Make use of the fact that for any [tex]x \ne 0[/tex] and integer [tex]n[/tex]:
[tex]\displaystyle \frac{1}{x^{n}} = x^{-n}[/tex].
For example, in this question:
[tex]\displaystyle \frac{1}{p^{2}} = p^{-2}[/tex].
[tex]\displaystyle \frac{1}{q^{5}} = q^{-5}[/tex].
Thus, the original expression would be equivalent to:
[tex]\begin{aligned}& \frac{81\, p^{6}\, q^{2}}{3\, p^{2} \, q^{5}} \\ =\; & \frac{81}{3}\, (p^{6}\, p^{-2})\, (q^{2}\, q^{-5}) \\ =\; & 27\, (p^{6}\, p^{-2})\, (q^{2}\, q^{-5})\end{aligned}[/tex].
Also make use of the fact that for any [tex]x \ne 0[/tex], integer [tex]m[/tex], and integer [tex]n[/tex]:
[tex]x^{m}\, x^{n} = x^{m + n}[/tex].
Thus:
[tex]\begin{aligned}& 27\, (p^{6}\, p^{-2})\, (q^{2}\, q^{-5}) \\=\; & 27\, p^{6 + (-2)}\, q^{2 + (-5)} \\ =\; & 27\, p^{4}\, q^{-3} \\ =\; & \frac{27\, p^{4}}{q^{3}}\end{aligned}[/tex].
