The three ways that in which the sum 7/4 is found are -
1/4 + 6/4 = 7/45/4 + 2/4 = 7/43/4 + 4/4 = 7/4What is the definition of the fraction?Fractions are categorized as a mathematical value that represents a portion of a whole. A fraction is a portion or segment of any quantity taken from the whole, which can be such a number, a fixed number, or a thing.Proper fractions are those whose numerator is less than the denominator. Proper fractions include 5/7, 3/8, and so on.An improper fraction is one where the numerator is greater than or equal to the denominator. It is always equal to or greater than that of the total. For instance, 4/3, 5/2, and so on.For the given question, the given number is 7/4.
This number can be formed in ways as;
1/4 + 6/4 = 7/45/4 + 2/4 = 7/43/4 + 4/4 = 7/4Thus, three ways that in which the sum 7/4 is found are made.

In a coin jar the ratio of dimes to pennies is 3 to 8. The number of pennies in the jar is 32. Answer the following questions based on this ratio. (Show ALL work.) *a) Why can’t the number of dimes be 10? Justify your answer by setting up & solving a proportion.
this is Solving Proportions
Answer:
Step-by-step explanation:
3 is to 8 as x is to 32
3/8=x/32
x=12
The number of dimes cannot be 10 because the number of dimes in the jar will be equal to 12.
What is the ratio?The ratio notion is used in mathematics when evaluating two or more numbers. It works as a comparison tool to demonstrate how big or small a particular number is. A ratio divides two quantities to compare them.
As per the data in the question,
The ratio of Dimes to pennies: 3 : 8
Number of Pennies in jar = 32
Assume that the number of Dimes in the jar is x.
So, the number of dimes will be,
x = (32 × 3)/8
x = 12 Dimes.

Answer:
x = 23.33333
y = 35
Step-by-step explanation:
3x+2y=70
Geometric figure: Straight Line
Slope = -3.000/2.000 = -1.500
x-intercept = 70/3 = 23.33333
y-intercept = 70/2 = 35
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 35/1 so this line "cuts" the y axis at y=35.00000
y-intercept = 70/2 = 35
Calculate the X-Intercept :
When y = 0 the value of x is 70/3 Our line therefore "cuts" the x axis at x=23.33333
x-intercept = 70/3 = 23.33333
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 35.000 and for x=2.000, the value of y is 32.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 32.000 - 35.000 = -3.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = -3.000/2.000 = -1.500
Geometric figure: Straight Line
Slope = -3.000/2.000 = -1.500
x-intercept = 70/3 = 23.33333
y-intercept = 70/2 = 35

Problem 3: The elevator at a business center has a weight limit of 1800 pounds. Assume the
average person weighs 160 pounds and has 3 pounds of items with them. What is the greatest
number of people that can ride the elevator at one time?
Answer
10
11
12
13
Weight limit of an elevator = 1800 pounds
Average weight of each person who comes in the elevator = 160 pounds
Quantity of items with them = 3 pounds
Let the number of people who can ride the elevator at one time be x.
Which means :
[tex] =\tt 160x + 3 = 1800[/tex]
[tex] = \tt160x = 1800 - 3[/tex]
[tex] = \tt160x = 1797[/tex]
[tex] =\tt x = \frac{1797}{160} [/tex]
[tex] =\tt x = 11[/tex]
Thus, number of people who can enter the elevator is 11.
▪︎Therefore, the correct option is (b) 11.

Answer:
6.75
Step-by-step explanation:
We are given that function
[tex]f(x)=\frac{9x-18}{4}[/tex]
5 is an element in the domain of f(x)
i.e
x=5
We have to find the corresponding element of 5 in the range of f(x).
Substitute x=5 in the given function
[tex]f(5)=\frac{9\times 5-18}{4}[/tex]
[tex]f(5)=6.75[/tex]
Hence, the corresponding element of 5 is 6.75 in the range.
When a biased coin is thrown 4 times, the probability of getting 4 heads is
16
81
Work out the probability of getting 4 tails when the coin is thrown 4 times.
Answer:
1/81
Step-by-step explanation:
P(H,H,H,H)=16/81
fourth root of 16/81= 2/3
so the probability of getting tails would be 1/3
probability of getting 4 tails would be:
P(T,T,T,T)=(1/3)^4
=1/81
The probability of getting 4 tails when the coin is thrown 4 times is 1/81
How to determine the probability?We have:
P(Head 4 times) = 16/81
This means that:
P(Head)^4 = 16/81
Take the 4th root of both sides
P(head) = 2/3
The probability of a tail is calculated as:
P(tail) = 1 - P(Head)
This gives
P(tail) = 1 - 2/3
P(tail) = 1/3
When thrown 4 times, we have:
P(tail)^4 = (1/3)^4
P(tail) = 1/81
Hence, the probability of getting 4 tails when the coin is thrown 4 times is 1/81

Angie is working on solving the exponential equation 23^x=6,; however she is not quite sure where to start. Using complete sentences, describe to Angie how to solve this equation.
And please don’t copy paste this and call it an answer
When you have problems like this you simply ask yourself what number do I have to multiply by 23 to get 6? This is how you might read this mathematical expression. So how do we solve the problem?
Well if x is the number that we have to multiply by 23 to get 6 that means that if we divide 6, 26 times we get x. So, x would be 6/23.
0.26
you would divide 23 on both sides

Jasmine buys 3 T-Shirts and 3 Hats for $11.25. The next day, he buys 4 T-Shirts and 2 Hats for $10. How much does each T-Shirt and each Hat cost? Write a system of equations that can be used to solve the problem. Then solve the problem.
Answer: Each shirt costs $1.25, and each hat costs $2.5.
Step-by-step explanation:
Let x= Cost per T-shirt, y = Cost per Hat.
As per given,
3x+3y=11.25 (i)
4x+2y=10 (ii)
Multiply 4 to equation (i)
12x+12y=45 (iii)
12x+6y= 30 (iv)
Eliminate (iv) from (iii), we get
6y= 15
⇒ y = 2.5
Put value of y in (i)
3x+3(2.5)=11.25
⇒3x+7.5=11.25
⇒3x= 3.75
⇒x= 1.25
Hence, each shirt costs $1.25, and each hat costs $2.5.
