What is fraction ?Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many components of a particular size there are when stated in ordinary English.
An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a correct fraction is smaller than the denominator.
The three main sorts of fractions are as follows. Proper fractions, improper fractions, and mixed fractions are these three types. The expressions with a numerator and a denominator are called fractions. We categorize its kinds based on these two parameters.

The following loan is discounted. Find (a) the discount, (b) the amount of money received, and (c) the true interest rate. P=$13,300.0, r=3 1/2%, t=4 years
a) The discount on the loan is $1,862.
b) The amount of money the borrower received on the discount loan is $11,438.
c) The true interest rate paid on the discounted loan is 4.1%.
What is a discount loan?A discount loan is a type of loan in which the interest (cost of borrowing) is deducted upfront or at the time the loan is granted.
The implication of getting a discount loan is that the amount received is less than the principal amount because the grantor has reduced it by interest and other fees (finance charges).
The principal = $13,300
Discount rate = 3¹/₂%
Time = 4 years
Discount = $1,862 ($13,300 x 3.5% x 4)
Amount received = $11,438 ($13,300 - $1,862)

Insurance cost is to be distributed among manufacturing, selling and administration in the ratio of 1/10 to 1/3 to 1/9. If the total cost was $12,005 how should it be distributed to these departments
Manufacturing should pay $2206.80, Selling should pay $7356.0and Administration should pay $2452.00
What is the distribution?Generally, To find out how much each department should pay, you can use the proportion of the cost that corresponds to their respective ratio.
First, calculate the total ratio by adding the three ratios together:
1/10 + 1/3 + 1/9 = 0.544
Then, divide the total cost by the total ratio to find the unit cost:
$12,005 / 0.544 = $22068.01
Next, multiply the unit cost by the ratio for each department to find out how much they should pay:
Manufacturing: $22068.01 x 1/10 = $2206.80
Selling: $22068.01 x 1/3 = $7356.0
Administration: $22068.01 x 1/9 = $2452.00

1. If m angle ABD = 60°, find m angle
BDC.
Answer:
If angle ABD = 60°, then angle BDC can be found using the fact that the measures of the angles in a triangle add up to 180°.
So, m(angle BDC) = 180 - (m(angle ABD) + m(angle BDA))
Therefore, m(angle BDC) = 180 - (60 + m(angle BDA))
So the measure of angle BDC is not fixed, it depends on the measure of angle BDA.

Quincy and Celine have to move 16 small boxes and 10 large boxes. the chart indicates the time that each person takes to move each type of box. they start moving the boxes at 9.00 a.m. the earliest time at which they can be finished moving all of the boxes is:
a. 9:41 a.m
b. 9:42 a.m
c. 9:43 a.m
d. 9:44 a.m
e. 9:45 a.m
The earliest time at which they can be finished moving all of the boxes is: d. 9:44 a.m
Quincy and Celine the earliest timeTo determine the earliest time at which Quincy and Celine can finish moving all of the boxes, we need to determine the maximum amount of time it will take for them to move all of the boxes. We can do this by calculating the time it will take for each person to move each type of box individually, and then adding those times together.
Quincy takes 1 minute to move a small box and 2 minutes to move a large box. Celine takes 2 minutes to move a small box and 3 minutes to move a large box.
So, for Quincy:Time to move 16 small boxes: 16 boxes * 1 minute/box = 16 minutes
Time to move 10 large boxes: 10 boxes * 2 minutes/box = 20 minutes
Total time for Quincy: 16 minutes + 20 minutes = 36 minutes
For Celine:Time to move 16 small boxes: 16 boxes * 2 minutes/box = 32 minutes
Time to move 10 large boxes: 10 boxes * 3 minutes/box = 30 minutes
Total time for Celine: 32 minutes + 30 minutes = 62 minutes
To get the earliest time they can finish moving all the boxes, we take the maximum of the two times:
Max(36 minutes, 62 minutes) = 62 minutes
Start time: 9:00 a.m.
End time: 9:00 a.m. + 62 minutes = 9:62 a.m.
So the earliest time they can finish moving all the boxes is 9:62 a.m.

Take the original data and divide it by the standard deviation to determine the z-scores. X is a symbol for the relevant data point. For the population from which you selected your sample, mu and sigma stand in for the mean and standard deviation.
What are z-scores?In terms of standard deviations above or below the mean, a data point's z-score quantifies this exact distance.

data point = mean standard deviation
Data point means with standard deviation equal to z
The same equation is given below in symbol form:
z= x−μ / σ
Some significant z-score details are as follows:
An elevated z-score indicates that the data point is.
When a data point has a negative z-score, it is below average.
The data point is considered to be roughly average if the z-score is near to 0.00.
If a data point's z-score is higher or lower than 3 33 or 3 3minus, the data point is deemed uncommon.

please help me :)
The Pinewoods Trail is longer than the Outlook Trail.
What are fractions?The definition of a fraction is a portion of a whole. A single object or a collection of objects might be entire. When we cut a piece of cake in real life from the entire cake, the part represents the percent of the cake. The word "fraction" is derived from Latin. "Fractus" means "broken" in Latin.
Given the length of Lake Trail = 4 and 3/5 mile
length of Lake Trail = 23/5 miles
length of Outlook Trail = 5 and 5/6 mile
length of Outlook Trail = 35/6 miles
length of Pinewoods Trail = 1 and 3/10 miles longer than Lake Trail
length of Pinewoods Trail = 33/10 + 23/5
length of Pinewoods Trail = (33 + 46)/10
length of Pinewoods Trail = 79/10 miles
comparing the length of Outlook Trail and Pinewoods Trail,
which is 35/6 and 79/10 miles respectively,
the common denominator for both is 30,
35/6 = (35*5)/(6*5)
35/6 = 175/30
and 79/10 = (79*3)/(10*3)

For what positive integers $c$, with $c < 100$, does the following quadratic have rational roots?
\[ 3x^2 + 20x + c \]
If you find more than one, then list the values separated by commas.
Answer: A quadratic of the form $ax^2 + bx + c$ has rational roots if and only if its discriminant, $b^2 - 4ac$, is a perfect square. In this case, the discriminant is $(20)^2 - 4(3)(c) = 400 - 12c$. So, we need to find the positive integers $c < 100$ that make $12c$ a perfect square.
The perfect squares that are less than $100$ are $1,4,9,16,25,36,49,64,81$, so the possible values for $c$ are $33,44,55,66,77,88$.

We can conclude that the division property of equality was done between step 4 and step 5.
What is linear equation ?
Linear equation can be defined as the equation in which the highest degree is one.
The Division Property of Equality states that when both sides of an equation are divided by the same nonzero number, both sides remain equal.
That is, if a, b, and c are real numbers such that a = b and c ≠0, then
a/c = b/c
At step 4: The equation was -6x = 57
To move to step 5, Paula had to divide both sides by the co-efficient of x (-6) in order to get the value of x. See below
-6x = 57
---- Divide both sides by -6 (Step 4)
-6x / -6 = 57 / -6
---- (Intermediary between step 4 and 5)
x = -9.5

less than it was at the start of last year.
Work out what the area of the glacier was
at the start of last year.
2
Give your answer in km² to 2 d.p.
The area of the glacier at the start of last year was 56.31 km², based on a percentage reduction of 0.2%.
What is a percentage decrease?A percentage decrease represents the difference between the starting and ending values, expressed as a percentage of the starting value.
In working out the percentage reduction, we determine the difference between the ending and starting values. This difference is divided by the starting value and multiplied by 100.
The current area of the glacier = 56.20 km²
The percentage reduction = 0.2%
Proportionately, the current area, in percentage terms = 99.8% (1 - 0.2%)
99.8% = 56.20 km²
100% = 56.31 km²
Thus, to 2 decimal points, the area of the glacier at the start of last year was 56.31 km².
