Answer:
BC = 8
Step-by-step explanation:
AB + BC = AC
4x + 8 + 3x - 4 = 32
7x + 4 = 32
7x = 32 - 4
7x = 28
x = 28/7
x = 4
BC = 3x - 4 = 3*4 - 4 = 12 - 4 = 8
Answer:
B) 8
Step-by-step explanation:
The Segment Addition Postulate basically states that the sum of the segments of a line will equal the length of the entire line.
Thus, AB+BC=AC, and we can substitute:
AB+BC=AC
(4x+8)+(3x-4)=32
4x+8+3x-4=32
7x+4=32
7x=28
x=4
Now that we have x, we can plug it in for segment BC:
BC=3x-4
3(4)-4
12-4
8
Therefore, choice B is correct

Jenny James has score of 78 89 90 and 96 on her first four test what score should she make out of 100 points in order to have at least an average of 90
Answers
Answer:
Jenny James would need to have a score of 97 out of 100 points in order to have an average of 90.
Step-by-step explanation:
Given that:
Scores of four tests
78, 89, 90 and 96
Let,
x be the score on fifth test.
Average is the sum of quantities divided by total number of quantities.
Average = 90
Average = [tex]\frac{Sum\ of\ scores}{No.\ of scores}[/tex]
Putting the values in the formula;
[tex]90=\frac{78+89+90+96+x}{5}\\90=\frac{353+x}{5}\\90*5=353+x\\450=353+x\\450-353=x\\x=97[/tex]
Hence,
Jenny James would need to have a score of 97 out of 100 points in order to have an average of 90.

3. A certain 50 cm spring will stretch (in

kg weight is attached to it?
Answers
Complete Question
A certain 50 cm spring will stretch (in cm) one fifth the weight (in kg) attached to it. How long will the spring be if a 35 kg weight is attached to it
Answer:
The value is [tex]L_w = 57 \ cm[/tex]
Step-by-step explanation:
The length of the spring is [tex]L = 50 \ cm = 0.5 \ m[/tex]
The mass attached to it is [tex]w = 35 \ kg[/tex]
Generally given from that the spring will stretch one fifth of the weight (in kg)attached to it , it then means that the new length of the spring whenever a weight is attached to it is mathematically represented as
[tex]L_w = L + \frac{W}{5}[/tex]
=> [tex]L_w = 50 + \frac{35}{5}[/tex]
=> [tex]L_w = 57 \ cm[/tex]

outlier = 69
range = 53
Step-by-step explanation:
Mean: add all values and divide by number of values 234 ÷ 8
Median: middle value if there are an odd number of data values, or the average of the two middle values if there are an even number of data values
Mode: data item seen most often
Outlier = data value that is extreme

They will rest after they hike `2` miles. Then they will hike the remaining `1.75` miles to the lookout. The trail the hikers will use to return from the lookout is `0.5` miles shorter than the trail they will use to go to the lookout. Each hiker will bring `0.25` gallons of water for each mile to and from the lookout. What is the total amount of water each hiker will need to carry?
Answers
Answer:
1.75 gallons
Step-by-step explanation:
First, we need to calculate how far the hike is going up the trail. They first hike 2 miles and then another 1.75 miles after resting so...
2 + 1.75 = 3.75 miles
The trail is 3.75 miles long, the question states that the return path is 0.5 miles shorter, therefore...
3.75 - 0.5 = 3.25 miles
Leaving us with a total hiking distance of
3.75 + 3.25 = 7 miles.
Since each hiker will carry 0.25 gallons for each mile we simply need to multiply this amount by the total number of miles in the hike.
7 * 0.25 = 1.75 gallons
Finally, we can see that each hiker will carry a total of 1.75 gallons of water for the entire hike.

Cory is a bird watcher he estimates that 30% of the birds he sees are american robins, 20% are dark eyed juncos and 20% are slnc sparrows. he designs a simulation.
Answers
Answer:
I think C. 0.75
Step-by-step explanation:
The probability of seeing at least one robin in the next 5 birds is 0.75
How to determine the probability?The representations are given as:
American robins = 0 to 2Dark eye juncos = 3 and 4Song sparrows = 5 and 6Others = 7 to 9Using the above representations, the numbers that represent an occurrence of seeing at least one robin in the next 5 birds are:
05716 16803 32177 92290 72794 14333 79019 05943 77510 74051 87238 86481 94036 12749 24005
The number of occurrence is:
Number = 15
The number of simulation is 20
So, the probability of seeing at least one robin is:
P = 15/20
Divide
P = 0.75
Hence, the probability of seeing at least one robin is 0.75

N is the term #
D is the common difference
First, let's find the common difference.
13 - (-15) = 28
Let's see if that checks out.
31-13 = 18
49 - 31 = 18
18 is not equal to 28
Since there is no common difference you cannot find the equation.

What are mathematics operations?
A mathematical operation is a function that converts a set of zero or more input values (also called "b" or "arguments") into a defined output value. The number of operands determines the operation's arity. Most commonly studied operations are binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive and multiplicative inverses.
• Zero-arity operations, or nullary operations, are constants, and mixed products are arity three operations, or ternary operations.
Calculating time of Betsy total work for getting paid :
Betsy Working from 6:00 AM to 12:00 PM = 6 hour
Betsy takes an unpaid lunch break from 12:00 PM to 1:00pm = 1 hour
Betsy Working from 1:00 PM to 3:30 PM = 2.5 hour
Now adding-up all the time = 6 + 1 + 2.5 hour = 9.5 hours or 9 hours 30 minutes.
Therefore, Betsy works for about 9 hours 30 minutes daily.
