Add an apple orchard, small bags contain 7 apples. Alexa and her family bought 91 apples for a party. How many small bags did they buy? I need the problem solved out thanks
In this problem, we'll need to divide the number of apples by the amount of apples in a small bag. This will leave us with the number of small bags needed for the amount of apples.
91 / 7 = 13
Therefore, Alexa and her family bought 13 small bags of apples.
A message can follow different paths through servers on a network. The sender’s message can go to one of five servers for the first step; each of them can send to five servers at the second step; each of those can send to four servers at the third step; and then the message goes to the recipient’s server.
a. How many paths are possible?
b. If all paths are equally likely, what is the probability that a message passes through the first of four servers at the third step?
Answer:
Number of way s= N=100
The probability that it passes through first of four servers at the third step is 0.25
Step-by-step explanation:
The total number of possible ways can be found out by multiplying the possibilities so the possibilities at the
1st stage is 5
2nd stage is 5
3rd stage is 4
4th stage is 1
So Number of way s= N= 5*5*4= 100
This can be solved by drawing a tree diagram as well.
Now the probability of finding the that a message passes through the first of four servers at the third step.
There are five paths
And we have to find the probability of four
So 5C1*5C4/100= 0.25
The probability that it passes through first of four servers at the third step is 0.25

(4x - 2) + (6x - 2). Please help brainly
Answer:
2 (5 x - 2) = 10 x - 4 or x = 2/5 (if you need to solve for x)
Step-by-step explanation:
Simplify the following:
4 x - 2 + 6 x - 2
Hint: | Group like terms in 4 x - 2 + 6 x - 2.
Grouping like terms, 4 x - 2 + 6 x - 2 = (4 x + 6 x) + (-2 - 2):
(4 x + 6 x) + (-2 - 2)
Hint: | Add like terms in 4 x + 6 x.
4 x + 6 x = 10 x:
10 x + (-2 - 2)
Hint: | Group the negative terms in -2 - 2 together and factor out the minus sign.
-2 - 2 = -(2 + 2):
10 x + -(2 + 2)
Hint: | Evaluate 2 + 2.
2 + 2 = 4:
10 x - 4
Hint: | Factor out the greatest common divisor of the coefficients of 10 x - 4.
Factor 2 out of 10 x - 4:
Answer: 2 (5 x - 2)
________________________________
if you need to solve for x then:
Solve for x:
10 x - 4 = 0
Add 4 to both sides:
10 x + (4 - 4) = 4
4 - 4 = 0:
10 x = 4
Divide both sides of 10 x = 4 by 10:
(10 x)/10 = 4/10
10/10 = 1:
x = 4/10
The gcd of 4 and 10 is 2, so 4/10 = (2×2)/(2×5) = 2/2×2/5 = 2/5:
Answer: x = 2/5
The US courts are reviewing a case to see whether a work has been refused fairly. What is an example of something they might consider when trying to decide whether the use was fair?
Answer:
The Purpose and Character of the usage of the work.
Step-by-step explanation:
In the United States of America, there is a terminology used in court called Fair use. This is a law in the USA that permits a limited use of one or more copyrighted materials without the need to first acquire permission from the holder of the copyright.
Thus, an example of something they might consider when trying to decide whether the use was fair is:
The Purpose and Character of the usage of the work.
This is because the original purpose of the work may have been altered to mean something new or different or it was just copied exactly into another work.
So knowing the purpose and character of usage of the work or material in question would be something they would consider

For an apartment complex, the association collects $158,000 from all of its 211 residents. What is the average rent per capita for this apartment complex?
Answer:
$748.42
Step-by-step explanation:
The average rent per capita is used to measure the average rent paid by a group of people in an apartment or an area. The rent per capita estimates the average rent charged for each resident. It is ratio of the total rent paid by the people in the area to the number of residents. Hence:
The average rent per capita = Total rent / number of residents = $158000 / 211 residents = $748.42
A bag contains three types of candy (gumdrops, jelly beans, and jawbreakers). If
chosen at random, the probability of getting a gumdrop is, and the probability
of getting a jellybean is 3. What is the probability of getting a jawbreaker?
Answer:
1/2
Step-by-step explanation:
First, I added the two numbers tat we had already.
1/6+1/3=1/6+2/6=3/6=1/2
Then, I subtracted the sum (1/2) from the total (1).
1-1/2=1/2
So, the probability of getting a jawbreaker is 1/2.

Simplify 3 + (b + 8) = 3 + (8 + b)
Answer:
−3b /8
Step-by-step explanation:
Answer:
b + 11 = 11 + b
Step-by-step explanation:
Combine like terms. Note that because you are adding for all terms, you can technically disregard the parenthesis:
3 + (b + 8) = b + 3 + 8 = b + 11
3 + (8 + b) = 3 + 8 + b = 11 + b
b + 11 = 11 + b (True).
I need help with example 4 plz
Answer:
a) [tex]y=1[/tex]
b) [tex]x=-3[/tex]
Step-by-step explanation:
Recall the forms of vertical and horizontal lines
Horizontal lines come in the form of [tex]y=0x+b[/tex], so the slope of the equation is zero. The value of b will be the y-value of the point that you're given.
This means that the equation for a would be y=1
Vertical lines come in the form of [tex]x=a[/tex]. For this line, the value of a would be equivalent to the x-value of the given point. Therefore, b. would be [tex]x=-3[/tex]

An equivalent fraction to 5/16 is
a. 5/32
b. 10/32
c.1/2
d. 10/16
Answer:
B is the answer..................
==================================================
Explanation:
Multiply top and bottom of the original fraction by 2
[tex]\frac{5}{16} = \frac{5*2}{16*2} = \frac{10}{32}[/tex]
Or you could go in reverse to divide each part of 10/32 by the GCF 2
[tex]\frac{10}{32} = \frac{10\div 2}{32\div 2} = \frac{5}{16}[/tex]
-------------------
Another alternative is to use your calculator to find the decimal version of each answer choice
5/32 = 0.15625
10/32 = 0.3125
1/2 = 0.5
10/16 = 0.625
And compare these results with 5/16 = 0.3125
Both 5/16 and 10/32 have the same decimal value 0.3125, which makes them equal.

what's the solution of the equation 4[x+2(3x-7)]=22x-65
Answer:
x = -3/2
Step-by-step explanation:
Let's solve your equation step-by-step.
4(x+2(3x−7))=22x−65
Step 1: Simplify both sides of the equation.
4(x+2(3x−7))=22x−65
(4)(x)+(4)(2(3x−7))=22x+−65(Distribute)
4x+24x+−56=22x+−65
(4x+24x)+(−56)=22x−65(Combine Like Terms)
28x+−56=22x−65
28x−56=22x−65
Step 2: Subtract 22x from both sides.
28x−56−22x=22x−65−22x
6x−56=−65
Step 3: Add 56 to both sides.
6x−56+56=−65+56
6x=−9
Step 4: Divide both sides by 6.
6x = -9
