128 pieces can be made after cutting the chain
Solution:
Given that, Amy cut 32 ft of chain into pieces that were each 1/4 ft long
To find: Number of pieces after cutting the chain
From given,
[tex]\text{Total length of chain } = 32 \text{ feet }\\\\\text{Length of 1 piece } = \frac{1}{4} \text{ feet }[/tex]
Thus the number of pieces after cutting the chain can be found by dividing the total length of chain by length of 1 piece
[tex]\text{Number of pieces} = \frac{\text{Total length of chain}}{\text{Length of 1 piece }}[/tex]
Substituting the values, we get
[tex]\text{Number of pieces} = \frac{32}{\frac{1}{4}}\\\\\text{Number of pieces} = 32 \times 4 = 128[/tex]
Thus 128 pieces can be made after cutting the chain

Answer:
tan(F) = z/(2y)
Step-by-step explanation:
Make use of the similarity relationship to find the side necessary to compute the tangent. Then make use of the tangent definition.*
__
The two triangles are given as being similar. That means corresponding sides have the same ratios:
EF/AC = ED/AB
ED = AB·(EF/AC) = 4z(x/(8x)) = (4/8)z = z/2
The mnemonic SOH CAH TOA reminds you that the tangent relationship is ...
Tan = Opposite/Adjacent
tan(F) = ED/DF = (z/2)/y
tan(F) = z/(2y)
_____
* Actually, you need to do this in reverse order: first you need to determine if you have all the necessary information to answer the question. You don't.
You need to know the length of side ED in terms of z. You notice that the corresponding side in similar triangle ABC has its length marked as a function of z, so all you need to find ED is the scale factor between the two triangles.
Since both hypotenuses are marked in terms of x, the scale factor is easily found.

Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]k=\frac{y}{x}[/tex] or [tex]y=kx[/tex]
Let
y ----> the price
x ----> the weight
Find the value of the proportionality constant for each ordered pair in each table
[tex]k=\frac{y}{x}[/tex]
If all the values of k are equal, then the table represents a proportional relationship between the variable x and the variable y
Table 1
For x=1.5 lb, y=$4.50 ----> [tex]k=\frac{4.5}{1.50}=3[/tex]
For x=2 lb, y=$9.00 ----> [tex]k=\frac{9.00}{2}=4.5[/tex]
The values of k are different
therefore
The table not represent a proportional relationship
Table 2
For x=10 g, y=$0.50 ----> [tex]k=\frac{0.50}{10}=0.05[/tex]
For x=15 g, y=$0.55 ----> [tex]k=\frac{0.55}{15}=0.04[/tex]
The values of k are different
therefore
The table not represent a proportional relationship
Table 3
For x=0.5 Kg, y=$0.75 ----> [tex]k=\frac{0.75}{0.5}=1.5[/tex]
For x=5 g, y=$7.50 ----> [tex]k=\frac{7.50}{5}=1.5[/tex]
The values of k are equal
therefore
The table represent a proportional relationship
Table 4
For x=1 oz, y=$2.00 ----> [tex]k=\frac{2}{1}=2[/tex]
For x=2 lb, y=$4.00
Convert lb to oz
Remember that
1 lb=16 oz
so
2 lb=2(16)=32 oz
For x=32 lb, y=$4.00 ----> [tex]k=\frac{4}{32}=0.125[/tex]
The values of k are different

P.S: we have set [tex]b=0[/tex] by default, because we are not given any information for it.
The line that represents a proportional relationship between y and x where the unit rate of change (or slope) is 0.4 can be plotted on a graph. Start from the origin and for each increase of 1 in x, y increases by 0.4. Plot these points and draw a straight line which represents this proportional relationship.
Explanation:To graph the line that represents a proportional relationship between y and x where the unit rate of change of y with respect to x is 0.4, you can start by creating a plot with an x- and y-axis. The y-axis represents the dependent variable and the x-axis represents the independent variable.
In this case, we're looking at a linear relationship, which means the line produced on the graph will be straight. This kind of straight-line graph typically uses the equation y = mx, where m is the slope (or unit rate of change) and x is the independent variable.
For this graph, the slope or unit rate of change is 0.4. This means that with every increase of 1 in x, y increases by 0.4. Plot some points on the graph starting from the origin (0,0). If x is 1, y will be 0.4 (1*0.4). If x is 2, y will be 0.8 (2*0.4). Keep plotting these points and connect them to draw the line. This line demonstrates the proportional relationship between x and y.

What is 25% of 37?
a. x/37 = 25/100
b. p = (0.25)37
c. 37/0.25 = w
d. 25/100 x 37
SELECT ALL THAT APPLY.
Answer:
A, B, D
Step-by-step explanation:
25% of 37
= 25/100 × 37
= 1/4 × 37
= 0.25 × 37
= 9.25
To find 25% of 37, you can use the equations: 'x/37 = 25/100', 'p = (0.25)37', and '25/100 x 37'. Option '37/0.25 = w' is not appropriate for finding 25% of 37.
Explanation:To find 25% of 37, you can use the following methods: a), b), and d).
These three options essentially represent how percentages can be calculated:
a) This represents 25% as a fraction (25/100) with 37 as the total (x/37). Solving for x gives you the answer. b) This signifies that 25% is converted to a decimal (0.25), and then multiplied by 37 to get the answer. d) It's similar to option a, but this time the fraction is multiplied by the total amount (25/100 * 37) directly making it a single step process.
Option c) is not suitable here because by dividing 37 by 0.25, you are finding out how many times 25% can fit into 37, not 25% of 37.

A horse walks around a circular track while its trainer stands in the center. The trainer is 14 feet from the horse at all times. About how far had the horse traveled after walking around the track 5 times? Explain
The horse traveled 439.6 feet after walking around the track 5 times
Solution:
Given that, horse walks around a circular track while its trainer stands in the center
The trainer is 14 feet from the horse at all times
Therefore, radius of circular track = 14 feet
The circumference of circle is the distance traveled by horse for 1 lap
The circumference of circle is given as:
[tex]C = 2 \pi r[/tex]
Where, "r" is the radius and [tex]\pi[/tex] is a constant equal to 3.14
[tex]C = 2 \times 3.14 \times 14\\\\C = 87.92[/tex]
Thus the distance traveled by horse for one time in circular track is 87.92 feet
About how far had the horse traveled after walking around the track 5 times?
Multiply the circumference by 5
[tex]distance = 5 \times 87.92\\\\distance = 439.6[/tex]
Thus the horse traveled 439.6 feet after walking around the track 5 times
If f(x)=2/3x+14, then find the value of f(12)
[tex]\dotfill[/tex]
To find the value of the given function, substitute x = 12 instead of x and evaluate.
Given function:
[tex]\sf f(x)=\cfrac{2}{3} x+14[/tex]
Substitute 12 for x:
[tex]\sf f(12)=\cfrac{2}{3}\times12+14[/tex]
Convert 12 to a fraction to make multiplying easier:
[tex]\sf f(12)=\cfrac{2}{3}\times\cfrac{12}{1}+14[/tex]
[tex]\sf f(12)=\cfrac{2\times12}{3\times1}+14[/tex]
[tex]\sf f(12)=\cfrac{24}{3}[/tex]
[tex]\sf f(12)=8[/tex]
>>> Therefore, the value of the function is 8.
The value of [tex]\( f(x) = \frac{2}{3}x + 14 \)[/tex] is 22.
To find the value of f(12), you simply need to substitute (x = 12) into the function f(x) and evaluate it:
Given: [tex]\( f(x) = \frac{2}{3}x + 14 \)[/tex]
Substituting x = 12:
[tex]\[ f(12) = \frac{2}{3} \times 12 + 14 \][/tex]
Now, let's calculate:
[tex]\[ f(12) = \frac{2}{3} \times 12 + 14 \]\[ = \frac{2}{3} \times 12 + 14 \]\[ = 8 + 14 \]\[ = 22 \][/tex]
So, [tex]\( f(12) = 22 \)[/tex].

$50 is invested biweekly in an
ordinary simple annuity, earning
3.5% interest per annum,
compounded biweekly. What will the
value of the annuity be in 10 years?
Answer:
The value of the annuity in 10 years will be US$ 15,552.90
Step-by-step explanation:
Let's use the ordinary simple annuity formula to calculate the value of the annuity in 10 years, this way:
FV = Future value of an annuity stream
PMT = Dollar amount of each annuity payment = US% 50
r = Interest rate = 3.5% compounded biweekly = 0.035/26
n = Number of periods in which payments will be made = 26 * 10 = 260
FV = PMT * [(1 + r)ⁿ − 1]/r
Now, replacing with the real values, we have:
FV = 50 * [(1 + 0.035/26)²⁶⁰ − 1]/(0.035/26)
FV = 50 * [(1.001346154)²⁶⁰ − 1]/0.001346154
FV = 50 * 0.41873217/0.001346154
FV = 50 * 311.058148
FV = 15,552.90

M and N are independent events. P(M | N) = 0.71. Find P(M)
Since M and N are independent events, [tex]P(M)=P(M|N)=0.71[/tex]
Step-by-step explanation:
Two events A and B are said to be independent when the probability of A happening does not depend on whether B has happened or not.
In other word, this condition can be rewrite as follows:
[tex]P(A|B)=P(A)[/tex]
where
[tex]P(A|B)[/tex] is the probability of A happening given that B has happened
[tex]P(A)[/tex] is the probability of A happening
In this problem, we have:
- M and N are independent events: so M does not depend on whether N occurs or not
Therefore,
[tex]P(M)=P(M|N)[/tex]
- Also, we know that
[tex]P(M|N)=0.71[/tex]
Therefore, it follows that

To find the total length of the wall, calculate the length built in 40 minutes (1200 cm) and divide by 3/4 to get the full length of 1600 cm, which is equivalent to 16 meters.
Explanation:
The question is asking us to determine the total length of the wall that a construction company is building, given that 3/4 of the wall is built in 40 minutes at a rate of 30 cm per minute. First, let's calculate the length of the wall built in 40 minutes:
Length built in 40 minutes = 40 minutes × 30 cm/minute = 1200 cmSince 1200 cm represents 3/4 of the wall, the full wall is:Full length = 1200 cm ÷ (3/4) = 1200 cm ÷ 0.75 = 1600 cmTo convert centimeters to meters: 1600 cm × (1 meter / 100 cm) = 16 metersThe total length of the wall is 16 meters.

1. Let's review the information given to us to answer the question correctly:
Current ratio of assets/liabilities = 2.9
Current assets = $ 377,000
Current liabilities = Currents assets/Ratio = 377,000/2.9 = $ 130,000
2. The board of directors determines that the current ratio must never be below 2.6. What is the maximum amount that the company can borrow?
Desired ratio of assets/liabilities = 2.6
Current assets = $ 377,000
Desired liabilities = $ Current assets/Ratio = 377,000/2.6 = $ 145,000
The maximum amount that the company X can borrow is $ 145,000
