3 1/2 - 3/4 =
3/4 is just a fraction, but you can think of 3/4 as a mixed numeral by writing 3/4 as 0 3/4. The whole part is 0 and the fractional part is 3/4.
= 3 1/2 - 0 3/4
Now we are subtracting two mixed numerals. You need to subtract the whole part, 0, from the whole part, 3, and the fractional part, 3/4, from the fractional part, 1/2.
For the fractional parts, we need a common denominator of 4.
= 3 2/4 - 0 3/4
Now we have both fractions with a common denominator of 4, but since we cannot subtract 3/4 from 2/4, we borrow 1 from 3 as 4/4.
3 goes down 1 to 2, and the 1 which is borrowed as 4/4 is added to the 2/4 to give you 2 6/4. 2 6/4 has the same value as 3 2/4. Now we have:
= 2 6/4 - 0 3/4
We subtract 0 from 2, and we subtract 3/4 from 6/4.
= 2 3/4

Gershon Smudgenick had 4 pounds of broccoli sprouts. He
went to Joe's Discount Bonanza and got some more. He ended up
with 11 pounds of broccoli sprouts. What is the fractional increase
in Gershon's broccoli sprouts? What is the percent increase in
Gershon's broccoli sprouts?
Answer: The fractional increase in Gershon's broccoli sprouts is 7/4 and the percent increase in Gershon's broccoli sprouts is 175%.
Step-by-step explanation:
The fractional increase in Gershon's broccoli sprouts is the difference between the final amount and the initial amount divided by the initial amount.
So in this case, it would be (11 - 4) / 4 = 7 / 4.
The percent increase in Gershon's broccoli sprouts is the fractional increase multiplied by 100.
So, it would be (7 / 4) * 100 = 175%.
It means Gershon's broccoli sprouts increased by 175% from 4 pounds to 11 pounds.

What is literacy rate?The proportion of people in a given age group who are reading and writing proficiently is known as the literacy rate. A person must be at least 15 years old to be considered an adult, 15 to 24 years old to be considered a young person, and 65 years old or older to be considered an elder. The ability to understand a brief, simple statement about daily life is typically used to measure it.
Most of the time, literacy includes numeracy as well, and measurements sometimes include a quick evaluation of arithmetic proficiency. It is important to distinguish between the literacy rate and the total number of literates and functional literacy, a more thorough assessment of literacy conducted over time and allowing for the determination of multiple proficiency levels.

One aircraft has a capacity of 64 more seats than a second aircraft. A third aircraft has 152 seats less than twice the seating capacity of the second aircraft. If their total number of seats is 1900, find the number of seats for each aircraft.
The number of seats in the first, second and third aircraft are 561 seats, 497 seats and 842 seats respectively
How to find the number of seats for each aircraft?A word problem is a mathematical exercise where significant background information on the problem is presented in ordinary language rather than in mathematical notation
Let F, S and T represent number of seats in the first, second and third aircraft respectively
We can set up three equations to represent the situation:
F = 64 + S --- (1)
T = 2S - 152 --- (2)
F + S + T = 1900 --- (3)
Put (1) and (2) in (3):
F + S + T = 1900
(64 + S) + S + (2S - 152) = 1900
64 + S + S + 2S - 152 = 1900
4S - 88 = 1900
4S = 1900 + 88
4S = 1988
S = 1988/4
S = 497 seats
F = 64 + S
F = 64 + 497 = 561 seats
F + S + T = 1900
561 + 497 + T = 1900
1058 + T = 1900
T = 1900 -1058 = 842 seats

Jordan has 8 coins in his pocket. They are a combination of dimes and quarters. If they total to $1.25, how many of each coin does he have
Answer:
q=quarters, d=dimes
q+d=8
.25q+.1d=1.25
Let's set the first equation to equal d.
d=8-q
.25q+.1(8-q)=1.25
Distribute.
.25q+.8-.1q=1.25
Combine Like Terms
.15q+.8=1.25
Subtract .8
.15q=.45
Divide by .15
q=3
Now, let's solve for d in the first equation.
d+3=8
Subtract 3, and you get d=5
So, there are 5 dimes and 3 quarters in Maribel's pocket.
Check: .25(3)+.1(5)=1.25
.75+.5=1.25
1.25=1.25 which is true.
Pls mark me as brainliest!Jordan has 3 quarters and 5 dimes in his pocket that total to $1.25.
Explanation:Let's assume Jordan has x number of quarters and 8 - x number of dimes in his pocket.
Each quarter is worth 25 cents, so the value of the quarters is 25x cents.
Each dime is worth 10 cents, so the value of the dimes is 10(8-x) cents.
The sum of the values of the quarters and dimes should be equal to $1.25, which is 125 cents. So, we can set up the equation: 25x + 10(8-x) = 125.
Simplifying the equation, we get 25x + 80 - 10x = 125. Combining like terms, 15x + 80 = 125. Subtracting 80 from both sides, 15x = 45. Finally, dividing both sides by 15, we find x = 3.
Therefore, Jordan has 3 quarters and 8 - 3 = 5 dimes in his pocket.

What does the word function refer to?Mathematics includes the study of numbers and their variations, equations and associated structures, and the regions and potential uses of geometry. A "function" is the connection between a collection of inputs that individually produce a related output. An output-input relationship known as a function is one in which each input leads to a single, identifiable outcome.
Here,
Because there are no restrictions on the kind of rational function, it is possible to build one from each of the 3 asymptotes.

Davis has $5.40 in his bank account on his fourth birthday. If his parents add $0.40 to his bank account every week, when will he have enough to buy the new Smokin' Derby race car set which retails for $24.99
Answer:
49 weeks
Step-by-step explanation:
y = mx + b
y is the total amount saved
x is the number of weeks
24.99 = .4x + 5.40 Solve for the number of months Subtract 5.40 from both sides
24.99 - 5.40 = .4x + 5.40 -5.40
19.59 = .4x Divide both sides by .4

A study shows that 80% of the population of a city have brown eyes and 20% do not. The study also shows that 30% of the people who do not have brown eyes do not have brown hair, while 90% of the people who have brown eyes have brown hair. A relative frequency table was constructed for this data. What is the largest marginal relative frequency and its interpretation?
0.72; Individuals with brown eyes
0.80; Individuals with brown eyes
0.86; Individuals with brown hair
0.90; Individuals with brown hair
Answer: I believe the answer is A; 0.72
Answer: The largest marginal relative frequency is 0.90 and it represents the probability of an individual having brown hair given that they have brown eyes.
Step-by-step explanation:
The reason why 0.90 represents the probability of an individual having brown hair given that they have brown eyes is because the study shows that 90% of the people who have brown eyes also have brown hair. This is a conditional probability, which means that it is the probability of one event happening given that another event has already happened. In this case, the event of having brown hair is conditional on the event of having brown eyes. The probability of 0.90 is calculated by taking the total number of individuals with brown eyes and brown hair and dividing it by the total number of individuals with brown eyes. The number is large because 90% of the individuals with brown eyes have brown hair, it is the largest because it is the highest probability among the other marginal relative frequencies. This indicates that the majority of people with brown eyes also have brown hair
Trigonometry (Law of Sines)
The measures, using the Law of Sines, are given as follows:
m < B = 119º. BC = 20.13.AC = 41.62.What is the law of sines?The law of sines states that the ratio between the sine of each angle and the side length opposite to this angle has to be equal for all the angles in the problem.
The sum of the measures of the internal angles of a triangle is of 180º, hence the measure of angle B is given as follows:
m < B + 25 + 36 = 180
m < B = 180 - (25 + 36)
m < B = 119º.
Then the length BC is obtained as follows:
sin(25º)/BC = sin(36º)/28
BC = 28 x sin(25º)/sin(36º)
BC = 20.13.
The length AC is obtained as follows:
sin(119º)/AC = sin(36º)/28
AC = 28 x sin(119º)/sin(36º)
AC = 41.62.
