Answer:
11
Step-by-step explanation:
1+red/3=4/1 so 1+red=12 so red=11. we should add 11 red counters
Answer:
Add 15 red counters
Step-by-step explanation:
Number of red counter is 1
Number of blue counter is 3
1:3⇒4:1
Now to make ratio reverse you need to add 11 (12-1) more red counters so that ratio becomes
12:3=4:1

a graph passes through the points (0,2),(1,3), and (2,4). Does this graph represent a linear function or a non linear function?
9514 1404 393
Answer:
linear
Step-by-step explanation:
The slope of the line between the first pair of points is ...
m = (y2 -y1)/(x2 -x1)
m = (3 -2)/(1 -0) = 1/1 = 1
The slope of the line between the second pair of points is ...
m = (4 -3)/(2 -1) = 1/1 = 1
The slopes are the same, so the points are on the same line. The graph is that of a linear function.
Elise is making punch for the party that requires 2 parts of fruit juice for every 5 parts of ginger ale. To make the punch, she uses 18 ounces of fruit juice and 3 containers of ginger ale. How many ounces are in each container of ginger ale?
Given:
Elise is making punch for the party that requires 2 parts of fruit juice for every 5 parts of ginger ale.
To make the punch, she uses 18 ounces of fruit juice and 3 containers of ginger ale.
To find:
The number of ounces in each container of ginger ale.
Solution:
Let n be the number of ounces in each container of ginger ale.
According to the question, the ratio of fruit juice and ginger ale is 2:5. it means,
[tex]\dfrac{\text{Fruit juice}}{\text{Ginger}}=\dfrac{2}{5}[/tex]
[tex]\dfrac{18}{\text{Ginger}}=\dfrac{2}{5}[/tex]
[tex]5\times 18=2\times \text{Ginger}[/tex]
[tex]90=2\times \text{Ginger}[/tex]
Divide both sides by 2.
[tex]45=\text{Ginger}[/tex]
So, ginger required for punch is 45 ounces.
Number of containers = 3
Number of ounces in each container of ginger ale = n
Number of ounces in 3 containers of ginger ale = 3n
Now,
[tex]3n=45[/tex]
Divide both sides by 3.
[tex]n=15[/tex]
Therefore, 15 ounces are in each container of ginger ale.

Answer:
the answer is b
Step-by-step explanation:
in word for, 5.004 is ____. five thousand, four five and four hundredths five and four thousandths five, four hundredths
Answer:
In word form, 5.004 is five and four thousandths.
Step-by-step explanation:
The part to the left of the decimal is simple - it's just five.
The part to the right of the decimal is a bit more complicated. The digit one place to the right of the decimal is the tenths place. The digit to the right of the tenths place is the hundredths place. The digit to the right of the hundredths place is the thousandths.
With that in mind, you should find that the number 4 is in the thousandths place. So, your answer is five and four thousandths.
Hope this helped!
Which of the following expressions is equal to 2x^2 +8?
A. (2x - 4i)(x-2i)
B. (2x-4i)(x+2i)
C. (2x-2i)(x+6i)
D. (2x +4i)(x+2i)
Answer:
i think of
Step-by-step explanation:
c is your answer
Answer:
B
Step-by-step explanation:
Expanding the products using FOIL , noting that i² = - 1
A
(2x - 4i)(x - 2i)
= 2x² - 4ix - 4ix + 8i²
= 2x² - 8ix - 8 ≠ 2x² + 8
B
(2x - 4i)(x + 2i)
= 2x² + 4ix - 4ix - 8i²
= 2x² + 8 ← True
C
(2x - 2i)(x + 6i)
= 2x² + 12ix - 2ix - 12i²
= 2x² + 10ix + 12 ≠ 2x² + 8
D
(2x + 4i)(x + 2i)
= 2x² + 4ix + 4ix + 8i²
= 2x² + 8ix - 8 ≠ 2x² + 8
Thus
(2x - 4i)(x + 2i) = 2x² + 8 → B

Please help! if abcd is dilated by a factor of 3, the coordinate of b would be
Answer:
(-6, 6)
Step-by-step explanation:
The coordinates of B to start with is
(-2, 2)
To dilate this by a factor of 3....
-2 * 3 = -6
2 * 3 = 6
The new coordinates of B' would be
(-6, 6)
A few things to know:
- The number 3 is called a "scale factor"
- Dilation means we are multiplying all the (X, Y)'s by the scale factor
- If the scale factor is greater than 1, the size of the shape overall increases
- If the scale factor is less than 1, the size of the shape overall decreases
- If the scale factor is negative, the shape size stays the same. The shape just rotates 180 degrees and moves to the opposite quadrant.
Answer:
-9,-1
Step-by-step explanation:
this is for A
I was looking for it so here you go
you multiply your x and Y by 2

Which input value produces the same output value for the two functions on the graph?
f)--x1
ot) -x-2
3
g(x)
9514 1404 393
Answer:
x = 3
Step-by-step explanation:
Each line shows you the output value for a given input value. If you want a particular input value to give the same output for both functions, then you need to find the point where the lines cross. This question asks for the input value at that point, the x-coordinate.
The lines cross at (x, y) = (3, -1), so x = 3 produces the same output from both functions.

If he walks at a constant rate, what is the total amount of time he will spend walking to the library? Step 1: StartFraction 5 Over 16 EndFraction divided by one-third = h Step 2: StartFraction 16 Over 5 EndFraction times StartFraction 3 Over 1 EndFraction = h Step 3: StartFraction 48 Over 5 EndFraction = h Answer: 9 and three-fifths = h What was Joylin's first error?
Answer:
She replaced both the divisor and the dividend with their reciprocals when changing division to multiplication in step 2.
Step-by-step explanation:
She switched the divisor and the dividend when creating an equation to model the problem in step 1.
She replaced both the divisor and the dividend with their reciprocals when changing division to multiplication in step 2.
She multiplied the two numerators and the two denominators to generate her product in step 3.
She reduced the improper fraction incorrectly when getting her final answer.
5/16 = 1/3h
Correct steps
Step 1:
h = 5/16 ÷ 1/3
Step 2:
h = 5/16 × 3/1
Step 3:
h = (5*3) / (16*1)
= 15/16
h = 15/16
Incorrect steps:
Step 1: StartFraction 5 Over 16 EndFraction divided by one-third = h
5/16 ÷ 1/3 = h
Step 2: StartFraction 16 Over 5 EndFraction times StartFraction 3 Over 1 EndFraction = h
16/5 × 3/1 = h
Step 3: StartFraction 48 Over 5 EndFraction = h Answer: 9 and three-fifths = h
48/5 = h
9 3/5 = h

Brian buys a computer for £3600. It depreciates at a rate of 5% per year. How much will it be worth in 2 years? Give your answer to the nearest penny where appropriate.
Answer:
£3591
Step-by-step explanation:
Brian buys a computer for £3600. It depreciates at a rate of 5% per year. How much will it be worth in 2 years? Give your answer to the nearest penny where appropriate.
The formula for Depreciation rate =
P = Po × e^-rt
P = Amount after depreciation
Po = Initial amount = £ 3600
r = depreciation rate = 5% = 0.05
t = time in years = 2
Hence:
P = £3600 × e ^ -0.05 × 2
P =£ 3600 × e-0.0025
P = £ 3591.0112406
Approximately = £3591

9 added to twice a number is the same as 27 reduced by 4 times the number
Answer:
x = 12
Step-by-step explanation:
Let the number be x.
9 added to twice a number is the same as 27 reduced by 4 times the number
If we add 9 to the number = (9+x)
If 27 reduced by 4 times the number = (4x-27)
ATQ,
(9+x) = (4x-27)
Taking like terms together,
x-4x = -27-9
-3x = -36
x = 12
Hence, the number be 12.

20 balloons have to be devided between a group A and Group B in the ratio 2:3. How many balloons will each group receive?
Answer:
There are 8 and 12 balloons for groups A and B, respectively.
Step-by-step explanation:
The ratio 2 : 3 means that there are 2 balloons in group A for each 3 balloons in the group B. The amounts of balloons asigned to each groups are determined by the following formulas:
Group A
[tex]n_{A} = \frac{2}{2+3}\cdot (20)[/tex]
[tex]n_{A} = 8[/tex]
Group B
[tex]n_{B} = \frac{3}{2+3}\cdot (20)[/tex]
[tex]n_{B} = 12[/tex]
There are 8 and 12 balloons for groups A and B, respectively.

school lunches cost $14.50 per week. About how much would 5.5 weeks cost of lunches
Answer:
The answer should be about $81.20
Step-by-step explanation:
$14.50 x 5weeks = $72.50
A school week is usually 5 days.
The middle of the week is Wednesday, so that's 3 whole days.
$14.50 / 5days = $2.90 per day
$2.90 x 3days = $8.70
$72.50 + $8.70 = $81.20
