To find equivalent fractions, multiply the numerator and denominator of a given fraction by the same number to achieve the desired denominator. For example, 3/4 becomes 9/12 and 1/2 becomes 3/6 when transformed to have denominators of 12 and 3 respectively.
Explanation:To solve the question of completing each equation so that it shows equivalent fractions, we will use the concept of multiplying the numerator and denominator of a fraction by the same number to find an equivalent.
Examples:For the fraction 3/4, to find its equivalent with a denominator of 12, we would multiply both the numerator and denominator by 3, because 4 times 3 equals 12. Thus, we get the equivalent fraction: 3/4 = 9/12.
To find an equivalent fraction for 1/2 with a denominator of 3, we multiply both the numerator and denominator by 3/6 because 2 times 3 equals 6. The equivalent fraction is 1/2 = 3/6.
If we need an equivalent for 2/1 with a denominator of 4, we multiply both the numerator and denominator by 4 because the common denominator we are aiming for is 4. The equivalent fraction is then 2/1 = 8/4.
Note that we always ensure the multiplication factor makes the denominators equal, since that is the requirement for fractions to be equivalent.
The equivalent fractions are:
1. [tex]\( \frac{1}{4} = \frac{3}{12} \)[/tex]
2. [tex]\( \frac{4}{5} = \frac{8}{10} \)[/tex]
3. [tex]\( \frac{1}{6} = \frac{2}{12} \)[/tex]
To complete each equation and show equivalent fractions, we need to find the missing numerator or denominator that, when filled in, will make the fractions equivalent.
1. [tex]\( \frac{1}{4} = \frac{3}{12} \)[/tex]
Explanation: To find an equivalent fraction for [tex]\( \frac{1}{4} \)[/tex] with a denominator of 12, we notice that we can get from 4 to 12 by multiplying 4 by 3 (4 * 3 = 12). So, to make the fractions equivalent, we also multiply the numerator by 3 (1 * 3 = 3). This gives us [tex]\( \frac{3}{12} \)[/tex], which is equivalent to [tex]\( \frac{1}{4} \)[/tex].
2. [tex]\( \frac{4}{5} = \frac{8}{10} \)[/tex]
Explanation: To find an equivalent fraction for [tex]\( \frac{4}{5} \)[/tex] with a denominator of 10, we notice that we can get from 5 to 10 by multiplying 5 by 2 (5 * 2 = 10). So, to make the fractions equivalent, we also multiply the numerator by 2 (4 * 2 = 8). This gives us [tex]\( \frac{8}{10} \)[/tex], which is equivalent to [tex]\( \frac{4}{5} \)[/tex].
3. [tex]\( \frac{1}{6} = \frac{2}{12} \)[/tex]
Explanation: To find an equivalent fraction for [tex]\( \frac{1}{6} \)[/tex], we want the denominator to be 12. To do this, we notice that we can get from 6 to 12 by multiplying 6 by 2 (6 * 2 = 12). So, to make the fractions equivalent, we also multiply the numerator by 2 (1 * 2 = 2). This gives us [tex]\( \frac{2}{12} \)[/tex], which is equivalent to [tex]\( \frac{1}{6} \)[/tex].

kiaria is 7 years alder tham jay . martha is twice as old as kiaria , the sum of their three ares is 7u , find the ratio of jay,s age to kiatias age to marhas age
Answer:
The ratio of Jay's age to Kiaria's age to Martha's age is 1: 2 : 4.
Step-by-step explanation:
Here, let us assume the age of jay = u years
So, the age of Kiaria = Age of Jay + 7 = u + 7
And, the age of Martha = 2 x ( age of Kiaria) = 2 ( u + 7)
Now, the sum of the ages = 7 u
⇒ (u) + (u + 7) + 2 ( u + 7) = 7 u
or, u + u + 7 + 2 u + 14 = 7 u
or, 4 u + 21 = 7 u
⇒ 3 u = 21 or u = 21/3 = 7
⇒ u = 7 years
Hence, the age of Jay = m = 7 years
Age of Kiaria = m + 7 = 7 + 7 = 14 years
Age of Martha =2 ( m+7) = 2 ( 7 +7) = 28 years
So, the ratio of Jay's age to Kiaria's age to Martha's age
is 7: 14: 28 = 1: 2 : 4
Hence, the final ratio of the ages is 1: 2 : 4.

the functions have the same domains
Step-by-step explanation:
because since the functions f(x) and g(x) have the same (x)
The only value that is in the domains of both functions is 0.
and the range of g(x) is all values less than or equal to 0 are correct.
What is a function?A relation is a function if it has only One y-value for each x-value.
The original function is f(x)=√x
As this is condition for √x function, x≥ 0
Domain= [0, infinity)
Range= [0, infinity)
After the reflection across x-axis and y-axis, we get a function,
g(x)=-√-x

Melanie took out a 20-year loan for $50,000 at an APR of 3.3%, compounded
monthly. Approximately how much would she save if she paid it off 6 years
early?
To calculate Melanie's savings from paying off a 20-year loan early, we compare total payments over 20 years to total payments made if the loan is finished 6 years early, focusing on the saved interest.
Without the monthly payment, we can't provide the exact savings figure, but it certainly would be less interest paid over 14 years versus 20 years.
Explanation:To calculate the savings from paying off a loan early, we need to compare the total amount paid under the original loan terms with the total amount paid if the loan is paid off early.
For Melanie's 20-year loan of $50,000 at an APR of 3.3% compounded monthly, we can use financial formulas or a calculator to determine the monthly payment and the total amount paid over the terms of the loan.
If the loan is paid off 6 years early, we would compare the interest paid over 14 years with the interest paid over 20 years.
However, without the exact formula being used or the provided calculator, we can't give an exact figure for the amount saved.
You will typically find that by paying off a loan early, you save money on interest that would have accrued over the remaining term of the loan.
To answer the question, Melanie would need to calculate or look up the monthly payment, multiply by the number of payments she would make in the two scenarios, and then subtract the smaller total from the larger one to determine her savings.

Pam goes skydiving and falls at a constant rate toward the ground. The equation y = -32x + 13,500 represents the situation where y is the height of Pam in feet above the ground and x is the seconds since she jumped.
Which statement describes the situation?
From a starting position of 13,500 feet above the ground, she is ascending at 32 feet per second.
From a starting position of 32 feet above the ground, she is descending at 13,500 feet per second.
From a starting position of 32 feet above the ground, she is ascending at 13,500 feet per second.
From a starting position of 13,500 feet above the ground, she is descending at 32 feet per second.
Answer:
From a starting position of 13,500 feet above the ground, she is descending at 32 feet per second.
Step-by-step explanation:
The equation is in slope intercept form. [tex]y=mx+b[/tex]
The slope (m) is -32. This can be used as a unit rate: -32 ft per second.
The y-intercept (b) is 13,500. It would make most sense if she started at 13,500 ft in height.
From a starting position of 13,500 feet above the ground, Pam is descending at 32 feet per second.
Answer:
The answer is B) From a starting position of 13,500 feet above the ground, she is descending at 32 feet per second.
Step-by-step explanation:
D does not make since because if you start at 32ft you can't fall 13,500ft. There is nowhere for you to go.
A and C don't make since because you can't fall upward.
A tv cost $450. During a special sale, its marked 1/3 off. What's the sale price of the tv
1/3 off means it is selling for 2/3 the original price.
Multiply the price by 2/3:
450 x 2/3 = (450 x 2) /3 = 900/3 = 300
The sale price is $300
Answer:
$300
Step-by-step explanation:
The TV's regular price is 450 dollars, and we are looking for the sale price after a third of it gets marked off.
We first need to find 1/3 of 450.
[tex]\frac{1}{3}* 450 = \frac{450}{3}=150[/tex]
One third of the original price is $150.
Now, we need to subtract 150 from 450.
[tex]450-150=300[/tex]
So, the sales price of the TV would be $300.

Kaitlin's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Kaitlin $5.50 per pound, and type B coffee costs $4.25 per
pound. This month's blend used twice as many pounds of type B coffee as type A, for a total cost of $448.00. How many pounds of type A coffee were used?
Answer:
The quantity of Type A coffee were used is 32 pounds .
Step-by-step explanation:
Given as :
The cost of type A coffee = $ 5.50 per pound
The cost of type b coffee = $ 4.25 per pound
The total cost of coffee = $ 448.00
The quantity of coffee of type B is twice than type A
Let The quantity of type A coffee = x pound
So, The quantity of type B coffee = 2 × x pound
Now, According to question
x × $ 5.50 + 2 x × $ 4.25 = $ 448
Or, x × $ 5.50 + x × $ 8.5 = $ 448
Or, 14 x = 448
∴ x = [tex]\frac{448}{14}[/tex]
I.e x = 32
∴ The quantity of type A coffee = 32 pound
And, The quantity of type B coffee = 2 × 32 = 64 pound
Hence The quantity of Type A coffee were used is 32 pounds . Answer
Final answer:
By setting up an equation based on the costs per pound and the relationship between quantities of coffee types A and B, we find that Kaitlin used 32 pounds of type A coffee for her blend.
Explanation:
We need to determine how many pounds of type A coffee were used in the blend, given that twice as many pounds of type B were used and that the total cost was $448.00. Let x be the pounds of type A coffee. Then, 2x will represent the pounds of type B coffee since twice as much type B is used compared to type A.
The cost equation can be represented as:
5.50x + 4.25(2x) = 448
Solving for x:
5.50x + 8.50x = 448
14x = 448
x = 448 / 14
x = 32
Therefore, Kaitlin used 32 pounds of type A coffee for her blend.
Each day Julian gives his dog, Banjo, 3 liters of water and 500 grams of food. Julian wants to track the total amount of the food and water he gives Banjo for 1 week. Julian plots a point at (3, 500) to represent the first day on a coordinate grid.
Then Julian uses a pattern to plot 6 more points. What are the coordinates and significance of the fifth point Julian plots?
A coordinate plane has a x-axis labeled
A.
(12, 2,500); In 5 days, Julian gave Banjo a total of 12 liters of water and 2,500 grams of food.
B.
(15, 2,500); In 5 days, Julian gave Banjo a total of 15 liters of water and 2,500 grams of food.
C.
(15, 2,500); On the fifth day, Julian gave Banjo 15 liters of water and 2,500 grams of food.
D.
(18, 3,000); In 5 days, Julian gave Banjo a total of 18 liters of water and 3,000 grams of food.
Answer:
The correct answer would be option C.
Step-by-step explanation:
Since he gives the dog 3 liters of water and 500 grams of food a day we know that on the fifth day the dog will have gotten 15 liters of water and 2,500 grams of food.
The required coordinate will be (15, 2,500)
Given that the coordinates of the point at (3,500) represent the first day on a coordinate grid if Julie uses a pattern to plot 6 more points, the pattern used can be geometric in nature.We can scale the coordinate point up by five units since we need to get the significance of the fifth point Julie plots.Hence the required coordinate will be (15, 2,500) which is interpreted as the fifth day, Julie gave Banjo 15 liters of water and 2,500 grams of food.

Let the cruise ship travel x hours before the container ship caught up and the container ship starts y hour after the cruise ship starts.
So, the distance traveled by the cruise ship in x hours = distance traveled by the container ship in (x - y) hours.
So, x - y = 10 ........ (1) (Given)
And 5x = 6(x - y)
⇒ x = 6y .......... (2)
Now, solving equations (1) and (2, we get 5y = 10, ⇒ y = 2 hours.
And x = 6y = 12 hours.
So, the cruise ship travels for 12 hours before the container ship caught up. (Answer)

Raffle tickets are sold and 6 prizes are available for the lucky draw. A total of 1,356 raffle tickets are sold for 4/5 dollars each and the 6 prizes cost 8 3/10 each. How much money was raise from the raffle tickets?
Answer:
US$ 1,084.80 were raised from the raffle tickets and US$ 1,035 are the profits after paying the prizes.
Step-by-step explanation:
1. Let's review the data given to us for solving the question:
Number of raffle tickets sold = 1,356
Cost of each raffle ticket = US$ 4/5
Number of prizes = 6
Cost of each prize = US$ 8 3/10
2. How much money was raised from the raffle tickets?
For easier calculation, let's convert the fraction numbers to decimal numbers:
Cost of each raffle ticket = US$ 4/5 = US$ 0.80
Cost of each prize = US$ 8 3/10 = US$ 8 + 0.30 = US$ 8.30
Now, we use this formula to calculate how much money was raised and the profits:
Profits = (Number of tickets sold * Cost of each ticket) - (Number of prizes * Cost of each prize)
Replacing with the real values, we have:
Profits = 1,356 * 0.80 - 6 * 8.30
Profits = 1,084.80 - 49.80
Profits = 1,035
US$ 1,084.80 were raised from the raffle tickets and US$ 1,035 are the profits after paying the prizes.
Final answer:
The total amount of money raised from the sale of 1,356 raffle tickets, priced at 4/5 dollars each, is $1,084.8.
Explanation:
To determine how much money was raised from the raffle tickets, we first need to calculate the total cost of each ticket and then multiply it by the total number of tickets sold. The question states that each raffle ticket is sold for 4/5 dollars. Since a total of 1,356 raffle tickets were sold, the total amount raised can be calculated as follows:
Total amount raised = Price per ticket × Total number of tickets
