Can someone help me I got these three questions wrong

Answers

Answer 1

Answer: We know that Frank is 1/4 Dana's age, so if Frank is represented by f, and Dana is represented by d, then the equation would be

1/4d = f

Secondly, we know that Neil's age is one-half the difference between Dana's and Frank's ages. Because of we learned that Frank is a fraction of Dana's age, we can infer that he is younger than Dana. So, if Neil's age is represented by the variable n, then the equation would be

1/2(d - f) = n

Finally, if we know that Dana is 16 years old, we can find out the other siblings ages using the equations we made above.

d=16
1/4d = f
1/4(16) = f
4 =f

1/2(d - f) = n
1/2(16-4) = n
1/2(12) = n
6=n

Therefore, Frank is 4 years old and Neil is 6 years old.

Manuel says that you can use one of the denominators of 5 / 6 and 11/30 when renaming these fractions using a common denominator. Why is this true?

Answers

It is true because 5/6 and 11/30 have a common denominator of 30. a common denominator is the bottom number of the fraction that will make it easy to add the two fractions.
example: 2/7 and 3/14 have a common denominator of 14 because you can multiple 2/7 by 2 to get an equivalent fraction of 4/14. now the denominator is the same and you can add the two fractions

Yasmine bought 6 gallons of apple juice. After filling up 4 bottles of the same size with apple juice, she had 0.3 gallon of apple juice left.

Answers

1.425 gallons/bottle.

Further explanation

Given:

Yasmine bought 6 gallons of apple juice.
After filling up 4 bottles of the same juice, she had 0.3 gallons of apple juice left.

Question:

What is the amount of apple juice in each container (or bottle)?

The Process:

Let the amount of apple juice in each bottle as X.

The two steps for obtaining X are as follows:

Step-1: the total amount of apple juice is the initial gallon amount subtracted by the remaining gallon amount.

$\boxed{ \ 6 \ gallons - 0.3 \ gallons = 5.7 \ gallons \ }$

Step-2: the total amount of apple juice divided by the number of bottles is the amount of apple juice in each bottle.

$\boxed{ \ X = 5.7 \ gallons / 4 \ bottles = \boxed{ \ 1.425 \ gallons/bottle \ } \ }$

Let's also consider the following quick steps.

Quick steps:

$\boxed{ \ X = ((6 - 0.3) \ gallons)/(4 \ bottles) = \boxed{ \ 1.425 \ gallons/bottle \ } \ }$

Therefore, the amount of apple juice in each container (or bottle) is 1.425 gallons.

Keyword: Yasmine bought 6 gallons of apple juice, after filling up 4 bottles, she had 0.3 gallons, what's the amount, in each bottle, subtracted by, divide, container

The size of each bottle that is filled by apple juice is $\boxed{\bf 1.425}$ .

Further explanation:

Given:

Yasmine bought $6$ gallons of apple juice.

She filled up $4$ bottles of same size.

She had $0.3$ gallon of apple juice left.

Calculation:

Consider the size of each bottle is $x$ gallons.

Total size of each bottle is $4x$ gallons.

Total amount of apple juice used in these $4$ gallons can be obtained by subtracting total amount of apple juice to remaining apple juice.

$\boxed{6-0.3=5.7}$

Therefore, total size of the $4$ bottles is $5.7\text{ gallon}$ .

Write the equation for the total size of the bottles.

$\boxed{4x=5.7}$

Now find the value of $x$ which gives the size of the bottles.

$\begin{aligned}4x&=5.7\nx&=(5.7)/(4)\nx&=1.425\end{aligned}$

Therefore, the size of each bottle that is filled by apple juice is $\boxed{\bf 1.425}$ .

Simple method:

First find the total size of bottle and then divide by $4$ .

The total size of each bottle can be obtained as follows:

$6-0.3=5.7$

The size of each bottle can be obtained as follows:

$(5.7)/(4)=1.425$

The size of each bottle that is filled by apple juice is $\boxed{\bf 1.425}$ .

1. The area of a rectangle is calculated by multiplying its width and lengh (which you can also understand by looking at the figures in table, column 3 is clearly column 2 times column 1) so we can write it Area = 8w
2.
A. y=0,8x+3
B. x is the number of miles driven by the taxi - y is the total cost of the ride

3. You can see that y=3x-5 in each of the case. Which means that y=37 for x=14
4. For each x in the table we can see that y is 3 times higher reduced by 2 units so we can write it y=3x-2
