how much of an 80% orange juice drink must be mized with 20 gallons of a 20% orange juice drink to obtain a mixture that is 50% orange juice
Answer by mananth(16075) (Show Source): You can put this solution on YOUR website!
--------percent ---------------- quantity
Orange juice 20 ---------------- 20 gal
Orange juice 80 ---------------- x gal
Mixture 50 ---------------- 20 + x gal
20 * 20 + 80 x = 50 ( 20 + x )
400 + 80 x = 1000 + 50 x
80 x + -50 x = 1000 - -400
30 x = 600
/ 30
x = 20
20 gal of 80 % Orange juice

The school ask you to determine the number scale of the drawing if the map length
actual 20 m boundary measurCs 16 cm on the diawing.
(Remember that both units must be the same
9514 1404 393
Answer:
1/125
Step-by-step explanation:
The map scale is usually shown as the ratio of the map distance to real-world distance. Here, that is ...
16 cm : 20 m = 16 cm : 2000 cm = 16 : 2000 = 1 : 125
The map scale is 1/125.

Find the median number of calls.
??? calls
Help please :)
The median number of calls is 235.
What are mean and median?The mean is the average value which can be calculated by dividing the sum of observations by the number of observations
Mean = Sum of observations/the number of observations
Median represents the middle value of the given data when arranged in a particular order.
Given;
The data;363, 311, 276, 222, 253, 235, 244

Answer:
v=-14.4
Step-by-step explanation:
Isolate v.
add - 3.1 to the other side
-7.9+3.1=-4.8
Now the problem is: -4.8 = v/3
Next, multiply both sides by 3
-4.8 times 3 = -14.4
v = -14.4
Answer:
-14.4
Step-by-step explanation:
-7.9 = -3.1 + (v/3)
- 4.8 = v/3
v = -14.4

Step-by-step explanation:
Given that:
f(x) = x²
Put x = 4x + 5
f(4x + 5) = (4x + 5)²
f(4x + 5) = (4x + 5)(4x + 5)
f(4x + 5) = 4x(4x + 5) + 5(4x + 5)
f(4x + 5) = 16x² + 20x + 20x + 25
f(4x + 5) = 16x² + 40x + 25

Answer:
A triangular prism
Explanation:

please help, i do not get this.
Answer:
k(x) = |x - 4| - 2
Step-by-step explanation:
So we know that k(x) is shifted 4 untis to the right and 2 units down. In an absolute value function, the value you move to the left will be positive and the value you move to the right will be negative. Since we are moving to the right, our value will be negative.
When you shift the function up or down, you will either subtract or add that value out side the absolute value. Since we are shifting down 2 units, that means we will be subtracting by 2.

15-(4m - 5) = 32 please help me
Answer:
m = -3
Step-by-step explanation:
15 - (4m - 5) = 32 (Given)
15 - 4m + 5 = 32 (Distributed)
20 - 4m = 32 (Added like terms)
20 - 4m - 20 = 32 - 20 (Subtract 20 on both sides)
-4m = 12 (Simplify)
-4m/-4 = 12/-4 (Divide -4 on both sides)
m = -3 (Simplify)

Create an example of a rational value between -8 and -9 and show the work
Answer:
-8.75
Step-by-step explanation:
Rational: a number that can be expressed as an integer or the quotient of an integer divided by a nonzero integer.
A rational number is a number that can be expressed as a fraction with an integer numerator and a positive integer denominator. Two different fractions may correspond to the same rational number. 1/2 = 2/4. Every whole number is a rational number. These can be written as N/1 = N, so they are rational numbers.
Using formula:
[tex]\to \bold{rational\ value =\frac{a+b}{2}}[/tex]
Given:
a=-8
b=-9
Calculating the rational number:
[tex]\to \bold{rational\ number=\frac{-8+(-9)}{2}}[/tex]
[tex]\bold{=\frac{-8-9}{2}}\\\\ \bold{=\frac{-17}{2}}\\\\ \bold{=- 8.5}\\\\[/tex]
