The number of lime-flavored candies in a candy machine is 85. If this is
17% of the number of candies in the machine. How many candies are in the
machine?
Answers
the answer is:500
step by step explanation: i don't know if i'm right by the way
500
Percent means per hundred.
Therefore,
17% = 17/100 = 0.17
Let the total number of gumballs be n. Then
17% of n = 85 means that
0.17 x n = 85
n = 85/0.17 = 500

a committee consisting of 4 faculty members and 5 students is to be formed. every committee position has the same duties and voting rights. there are 7 faculty members and 13 students eligible to serve on the committee. in how many ways can the committee be formed?
Answers
and
C(13, 5) = 13! / (5!(13-5)!) = (13 * 12 * 11 * 10 * 9) / (5 * 4 * 3 * 2 * 1) = 1287
Multiply these two combinations since the faculty members and students are selected independently:
Total number of ways to form the committee = C(7, 4) * C(13, 5) = 35 * 1287 = 45,045
Therefore, there are 45,045 ways to form the committee consisting of 4 faculty members and 5 students.
For faculty members:
There are 7 eligible faculty members, and we need to select 4 of them for the committee. This can be done using the combination formula:
C(7, 4) = 7! / (4!(7 - 4)!) = 35.
So, there are 35 ways to select 4 faculty members from the 7 eligible ones.
For students:
There are 13 eligible students, and we need to select 5 of them for the committee. Using the combination formula again:
C(13, 5) = 13! / (5!(13 - 5)!) = 1287.
Therefore, there are 1287 ways to select 5 students from the 13 eligible ones.
To form the committee, we multiply the number of ways to select faculty members by the number of ways to select students:
35 * 1287 = 44,895.
Hence, there are 44,895 ways to form the committee consisting of 4 faculty members and 5 students from the eligible candidates.
I'm not sure how to solve these types of questions, I need help. Thank you!

Answer:
The x-intercept is (-5, 0).
The y-intercept is (0, 5).
Step-by-step explanation:
To find the x-intercept, we set y = 0 and solve for x:
0 = 5 + x
x = -5
Therefore, the x-intercept is (-5, 0).
To find the y-intercept, we set x = 0 and solve for y:
y = 5 + 0
y = 5
Therefore, the y-intercept is (0, 5).
Answer:
x-intercept is (-5,0)
y-intercept is (0,5)
Step-by-step explanation:
We are given a linear equation and are asked to find the x- and y-intercepts of the equation.
\(\Huge{y=5+x\)
\(\hrulefill\)
What are x- and y-intercepts?In mathematics, the terms "x-intercept" and "y-intercept" refer to points where a graph intersects the x-axis and y-axis. They are important concepts in the study of functions and graphs.
The x-intercept is the point at which a graph crosses or intersects the x-axis. It represents the value of x when y is equal to zero. In other words, it is the value of x when the function or equation is satisfied with y = 0. The x-intercept is often denoted as (x, 0), where "x" is the x-coordinate of the point.
Similarly, the y-intercept is the point at which a graph crosses or intersects the y-axis. It represents the value of y when x is equal to zero. Geometrically, it is the point on the graph where x = 0. The y-intercept is often denoted as (0, y), where "y" is the y-coordinate of the point.\(\hrulefill\)
(1) - Finding the x-intercept
To find the x-intercept, you set y equal to zero and solve the equation for x.
\(y=5+x\\\\\\\text{Let y=0}\\\\\\\Longrightarrow 0=5+x\\\\\\\Longrightarrow \boxed{x=-5}\)
Thus, the x-intercept is (-5,0).
(2) - Finding the y-intercept
To find the y-intercept, you set x equal to zero and solve the equation for y.
\(y=5+x\\\\\\\text{Let x=0}\\\\\\\Longrightarrow y=5+0\\\\\\\Longrightarrow \boxed{y=5}\)
Thus, the y-intercept is (0,5).\(\hrulefill\)
We can check this answer using a graphing calculator. Simply type in the given function and see were the function crosses each axis. Refer to the attached image.
Write and then solve the proportion.
8 is to 12 as p is to 18.
Write and then solve the proportion.
8 is to 12 as p is to 18.
Answers
Answer:
p = 12
Step-by-step explanation:
if you're trying to solve for p in 8/12 = p/18,
First, you cross multiply so
(8*18) = (p * 12)
144 = 12p;
divide both sides by 12,
12 = p;
there fore p = 12
Answer:
It would be answer 8/12 = p/18 ; 12.
Step-by-step explanation:
if you do 18/12 = 1.5, and 1.5 x 8 = 12.

the temperature at 2 pm is 27° at 2 am the temperature has fallen to -4° what is the total difference in temperature from 2:00 pm to 2:00 am???
Answers
Answer:
The temperature difference is equal to 27-(-4)=31.
Step-by-step explanation:
Answer:
31° .
Step-by-step explanation:
we need to calculate the temperature difference between 2 pm and 2 am we can get the difference by subtracting the temperature at 2 am from the temperature at 2 pm
the temperature at 2 pm is 27°
the temperature at 2 am is -4°
the temperature difference between 2 pm and 2 am is:
27° - (-4)° = 31°

Step by step explanation:
Add up all of the numbers, so here it would be 70+30+40+110 and you would get 250 so then you divide each number by 250. 70 divided by 250 is .28 so u make that into a percentage which is 28%, 30 divided by 250 is .12 so 12%, 40 divided by 250 is .16 so 16%, and lastly, 110 divided by 250 is .44 so 44%

Let's solve....
Isolate for x first which is
\(x = \frac{3 + 3y}{4} \\ \)
\(substitute \: x = \frac{3 + 3y}{4} \\ \\ \brack \: 5 \times \frac{3 + 3y}{4} - 4y = 3 \\ \\ \)
Now simplify...
\( \brack \: \frac{15 - y}{4} = 3 \\ \\ = y = \frac{15 - 3}{4} \\ \\ = \frac{12}{4} \\ simplify \\ \\ \frac{ \cancel{12} ^{3} }{ \cancel{4}^{1} } \\ x = 3\)
Y=3
We need to find value of y first... now x
\(x = \frac{3 + 3 \times 3}{4} \\ \\ =x = \frac{3 + 9}{4} \\ \\ = x = \frac{12}{4} \\ simplify \: \frac{ \cancel{12}^{3} }{ \cancel{4} ^{1} } \\ \\ value \: of \: x = 3 \)

x = -1.3
I hope this is right, and I am sorry if this is wrong if it is! I rlly hope this helps you out and you can understand my method and the way I typed this!!
Step-by-step explanation:
We are going to use one of my fav methods! The substitution method!
Set this aside for now: 4x - 3y = 3 We gonna use this one: 5x - 4y = 3
5x - 4y = 3
= 5x - 3 = 4y
( also, the subtraction is with the 4y as a negative, so 4y would be positive if you moved it!)
Divide all of the equation by 4!
y = \(y = \frac{5x - 3}{4}\)
Now, you take take the other equation and substitute the y with what you have above!
\(4x - 3 times \frac{5x - 3}{4} = 3\)
you cross multiply 4( the denominator) with the other side that has only a three!
4x - 3 \(times 5x - 3\) = 12
4x - 15x - 3 = 12
-11x - 3= 12
Move the three to the other side become positive!
-11x = 15
divide both sides by -11
x = -1.3

Sula designs greeting cards for her friends. Each friend has a 30% chance to get a musical greeting card. Design a simulation that can be used to estimate the probability that a friend will receive a musical greeting card.
Answers
Here's a simple Python code that simulates the process:
```python
import random
num_friends = 1000 # the number of friends
num_musical_cards = 0 # the number of friends who received musical cards
# simulate the card distribution for each friend
for friend in range(num_friends):
if random.random() < 0.3:
num_musical_cards += 1
# calculate the probability of a friend receiving a musical card
prob = num_musical_cards / num_friends
print("Probability of a friend receiving a musical card:", prob)
```
In this simulation, we create a loop that simulates the card distribution for each friend. We randomly assign a musical card to each friend with a 30% chance. Then, we calculate the probability of a friend receiving a musical card by dividing the number of friends who received musical cards by the total number of friends.
You can adjust the `num_friends` and `random.random() < 0.3` parameters to match your specific scenario.

What is volume of a cylinder?
A cylinder is a three-dimensional solid that holds two parallel bases joined by a curved surface, at a fixed distance. These bases are normally circular in shape (like a circle) and the center of the two bases are joined by a line segment, which is called the axis.
The volume of a cylinder = πr²h
there are 7.48 liquid gallons in a cubic foot.
therefore in 1100 liquid gallons there will be 1300/7.48 = 173.7 ft³
147.1 = 3.14 × 2.6² ×h
147.1 = 21.2h
h = 173.7/21.2
h = 8.2ft(nearest tenth)
therefore the height of the tank is 8.2ft
