mandle is making 15 cups of fruit salad . what ration of grapes to blueberries should she use?
Answer:
12:3
Step-by-step explanation:
The first thing you should do for this case is to graph the data you have in the statement to see the relationship between grapes and blueberries.
The function represented by the table is
y = 0.25x
Then, as Mandie is making 15 glasses of fruit salad, we have:
y + x = 15
We have two equations and two unknowns that we must solve.
y = 0.25x
y + x = 15
Resolving
For x:
0.25x + x = 15
1.25x = 15
x = 15 / 1.25 = 12
For y:
y = 0.25x = 0.25 (12) = 3
Answer
The ratio of grapes to blueberries she should use is 12: 3

If
f(x) = x - 5
and
g(x) = 4x – 2
-
Find
f(g(x)) = 4x – [?]
-
Answer:
4x - 7
Step-by-step explanation:
To evaluate f(g(x)) substitute x = g(x) into f(x)
f(g(x)
= f(4x - 2)
= 4x - 2 - 5
= 4x - 7

The sum of ages of 3 siblings, Alice, Bruce and Chuck is 27. The sum of ages of Alice and Bruce is 14 and the sum of ages of Bruce and Chuck is 22. Find each sibling's age by using system of linear equations.
Answer:
Alice = 5
Bruce = 9
Chuck = 13
Step-by-step explanation:
alice= x
Bruce = y
Chuck = z
x+y+z= 27
x+y= 14
therefore z= 27-14= 13
Chuck = 13
y+13 (z) = 22
therefore y = 22-13= 9
Bruce = 9
9+13= 22
therefore x= 27 - 22= 5
Alice = 5
confirmation
5 + 9 + 13 = 27
5+9= 14
9 + 13 = 22
Each sibling's age i..e Alice be 5 years, Bruce be 9 years, and Chuck be 3 years.
Given that,
The sum of ages of 3 siblings, Alice, Bruce, and Chuck is 27. The sum of ages of Alice and Bruce is 14 and the sum of ages of Bruce and Chuck is 22.Here we assume Alice be x, Bruce be y, and Chuck be z.Based on the above information, the calculation is as follows:
x + y + z = 27
x + y = 14
So,
z = 27 - 14
= 13
i.e. Chuck = 13
Now
y + 13 (z) = 22
So,
y = 22 - 13
= 9
i.e. Bruce = 9
Now
9+13= 22
So,
x = 27 - 22
= 5
i.e. Alice = 5
Therefore we can conclude that each sibling's age i..e Alice be 5 years, Bruce be 9 years, and Chuck be 3 years.

Step-by-step explanation:
If the student has already read 2525 of the pages, how long will it take them to read the rest of the book? _____ minutes Your answer should be written as a decimal rounded to the nearest tenth if necessary.
The number of pages the student can read in a minute is an illustration of rates.
The time left to complete the whole book is 90 minutes
From the complete question, the student's rate is:
[tex]\mathbf{Rate = 50\ pages/hr}[/tex]
The number of pages is:
[tex]\mathbf{Total = 100\ pages}[/tex]
First, we calculate the time to read the whole book
[tex]\mathbf{Total\ Time = \frac{Total\ pages}{Rate}}[/tex]
[tex]\mathbf{Total\ Time = \frac{100\ pages}{50\ pages/ hr}}[/tex]
[tex]\mathbf{Total\ Time = 2\ hours}[/tex]
The number of the student has read is:
[tex]\mathbf{Pages = 25}[/tex]
Next, we calculate the time spent on the 25 pages
[tex]\mathbf{Time\ Spent = \frac{Pages}{Rate}}[/tex]
[tex]\mathbf{Time\ Spent = \frac{25\ pages}{50\ pages/hr}}[/tex]
[tex]\mathbf{Time\ Spent = 0.5\ hr}[/tex]
Convert to minutes
[tex]\mathbf{Time\ Spent = 30\ minutes}[/tex]
So, the time left is:
[tex]\mathbf{Time\ Left = Total\ Time - Time\ Spent}[/tex]
This gives
[tex]\mathbf{Time\ Left = 2\ hours- 30\ minutes}[/tex]
[tex]\mathbf{Time\ Left = 1\ hour, 30\ minutes}[/tex]
Convert to minutes
[tex]\mathbf{Time\ Left = 90\ minutes}[/tex]
Hence, the time left is 90 minutes

Answer:
It lets me add one now! The answer is 3.75
Step-by-step explanation:
1/4 of a unit is 25%
When converted to a decimal, 25% = .25
4 - .25 = 3.75
We can check this by using reversive property:
4 - .25 = 3.75
3.75 + .25 = 4

Step-by-step explanation:
The value of y varies directly with x. If x = 3, then y = 18. What is the value
of x when y = 84
The value of x when y = 84 is 14
From the question,
The value of y varies directly with x
That is,
y ∝ x
Introducing the constant of proportionality, k
We get,
y = kx
Also, from the question
If x = 3, then y = 18
Putting these values into the equation, we can determine the value of k
[tex]y = kx[/tex]
[tex]18 = k \times 3[/tex]
Now, divide both sides by 3
[tex]\frac{18}{3}=\frac{k \times 3}{3}[/tex]
[tex]6 = k[/tex]
∴ k = 6
Now, to determine the value of x when y = 84
We will put y = 84 and the value of k =6 into the equation
[tex]y = kx[/tex]
[tex]84 = 6 x[/tex]
Divide both sides by 6
[tex]\frac{84}{6} = \frac{6x}{6}[/tex]
[tex]14 = x[/tex]
∴ [tex]x = 14[/tex]
Hence, the value of x when y = 84 is 14

Step-by-step explanation:
Leila puts an integer into the "In" box of each machine.
She finds that the answer that appears in the "Out" box of Machine A is the same as the
answer that appears in the "Out" box of Machine B.
What was the answer produced by both machines?
Show how you figured it out
The machines represent equivalent expressions.
The output produced by both machines is 372
The equation represented on machine A is:
[tex]\mathbf{y = 2(5x + 3) - 24}[/tex]
The equation represented on machine B is:
[tex]\mathbf{y = 4(2(x + 11) - 7)}[/tex]
Where: x and y represent the inputs and the outputs, respectively
When the outputs are the same, it means:
[tex]\mathbf{y = y}[/tex]
So, we have:
[tex]\mathbf{2(5x + 3) - 24 = 4(2(x + 11) - 7)}[/tex]
Open brackets
[tex]\mathbf{10x + 6 - 24 = 8x + 88 - 28}[/tex]
[tex]\mathbf{10x - 18 = 8x + 60}[/tex]
Collect like terms
[tex]\mathbf{10x - 8x = 18 + 60}[/tex]
[tex]\mathbf{2x = 78 }[/tex]
Divide both sides by 2
[tex]\mathbf{x = 39 }[/tex]
Substitute 39 for x in [tex]\mathbf{y = 2(5x + 3) - 24}[/tex]
[tex]\mathbf{y = 2 \times (5 \times 39 + 3) - 24}[/tex]
[tex]\mathbf{y = 372}[/tex]
Hence, the output produced by both machines is 372

Answer:
[tex]x=\pm \sqrt{21}/7[/tex]
Step-by-step explanation:
We can add 9 to both sides of the equation to get [tex]21x^2=9[/tex].
We can divide both sides of the equation by 21 to get [tex]x^2=9/21[/tex].
We take the square root of both sides of the equation to get [tex]x=\pm \sqrt{9/21}[/tex].
However, that isn't in the form we need.
We know that [tex]\sqrt{9/21}=\sqrt{9}/\sqrt{21}=3/\sqrt{21}=3\sqrt{21}/(\sqrt{21}*\sqrt{21})=3\sqrt{21}/21=\sqrt{21}/7[/tex]
so the answer is really [tex]x=\pm \sqrt{21}/7[/tex] and we're done!
