Booster Juice needs to combine three different juices to make a smoothie, and one cup of smoothie needs one pound of three different juices combined. Assume one pound of apple juice costs $1, one pound of orange juice costs $2, and one pound of peach juice costs $4.
a. What would be the price of the smoothie if Booster Juice makes the smoothie by combining 30% of apple juice, 20% orange juice and 50% of the peach juice.
b. What would be the price of the smoothie if the Booster Juice makes the smoothie by using all three equally.
Answer:
A.) $2.70
B.) $2.33
Step-by-step explanation:
Given that:
Smoothie is made from 3 different juice ;
1 cup of smoothie requires 1 pound combination of 3 different juices.
Cost of 1 pound of apple juice = $1
Cost of 1 pound of orange juice = $2
Cost of 1 pound of peach juice = $4
A.) What would be the price of the smoothie if Booster Juice makes the smoothie by combining 30% of apple juice, 20% orange juice and 50% of the peach juice.
30% of 1 pound apple juice :
(30/100) * $1 = $0.3
20% of 1 pound orange :
(20/100) * $2 = $0.4
50% of 1 pound peach :
(50/100) * $4 = $2
Hence, price of smoothie = $(0.3 + 0.4 + 2) = $2.70
b. What would be the price of the smoothie if the Booster Juice makes the smoothie by using all three equally.
If all three juice are used equally:
100% / 3 = 33.333% = 0.3333
0.3333 * $1 = $0.333
0.333 * $2 = $0.667
0.333 * $4 = $1.332
Hence, price of smoothie :
$(0.333 + 0.667 + 1.332) = $2.332

2(3x – 5) = 8
Solve using distributive property
Answer:
x = 3
Step-by-step explanation:
Step 1: Write equation
2(3x - 5) = 8
Step 2: Solve for x
Distribute 2: 6x - 10 = 8Add 10 to both sides: 6x = 18Divide both sides by 6: x = 3Step 3: Check
Plug in x to verify it's a solution.

Please help me with this question step by step. A rectangle has a width of 2x exponent 2 +4x+1) and a length of (8-x). What is the function for the area of the rectangle?
Answer:
A = (2x² + 4x + 1) (8 − x)
A = -2x³ + 12x² + 31x + 8
Step-by-step explanation:
W = 2x² + 4x + 1
L = 8 − x
Area is width times length.
A = (2x² + 4x + 1) (8 − x)
If you wish, you can simplify with distribution.
A = 8 (2x² + 4x + 1) − x (2x² + 4x + 1)
A = 16x² + 32x + 8 − 2x³ − 4x² − x
A = -2x³ + 12x² + 31x + 8

Convert the measurement as indicated.
31 pt=__ gal __ qt __ pt
HELPPP PLEASEEEE
Answer:
31pt=3875gal
Step-by-step explanation:
To convert a pint measurement to a gallon measurement, divide the volume by the conversion ratio. One gallon is equal to 8 pints, so use this simple formula to convert:
gallons = pints ÷ 8
The volume in gallons is equal to the pints divided by 8.
For example, here's how to convert 5 pints to gallons using the formula above.
5 pt = (5 ÷ 8) = 0.625 gal
Pints and gallons are both units used to measure volume. Keep reading to learn more about each unit of measure.
Pints
The US liquid pint is a unit of fluid volume equal to one-eighth of a gallon, one-half of a quart, or two cups. The liquid pint should not be confused with the dry pint (US) or the imperial pint, which are different units.
The pint is a US customary unit of volume. Pints can be abbreviated as pt; for example, 1 pint can be written as 1 pt.
Gallons
The US liquid gallon is a unit of fluid volume equal to four quarts, eight pints, or sixteen cups.[1] The US liquid gallon should not be confused with the US dry gallon or the imperial gallon, which are different units of measure.
The gallon is a US customary unit of volume. Gallons can be abbreviated as gal; for example, 1 gallon can be written as 1 gal.

Find the x and y intercepts of the graph
of the equation 13x + 5y = 65.
Answer:
x-intercept: (5,0)
y-intercept: (0,13)
Step-by-step explanation:
x-intercepts are when y=0, so plug it into the equation
[tex]13x+5\cdot 0=65[/tex]
[tex]x=5[/tex] so (5,0)
y-intercepts are when x=0, so plug it into the equation
[tex]13\cdot 0 + 5y=65[/tex]
[tex]y=13[/tex] so (0,13)

[tex]x = \frac{32}{3}[/tex]
Step-by-step explanation:
Simplify: 6x - 11 = 53Add 11 to each side, so it now looks like this: 6x = 64Divide each side by 6 to cancel out the 6 next to x. It should now look like this: x = 32/3I hope this helps!
6,397 x 349 ≈ __________ x __________ = 1,800,000
i need help really bad
6,397 x 349 = 6000 x 300 = 1,800,000
I rounded 6,397 to 6,000
I rounded 349 to 300
Multiplying 6,000 and 300 is the same as multiplying 6 and 3 to get 18, then we tack on five zeros to the result. The five zeros come from the total number of zeroes in 6000 and 300
We have 3 zeros in 6000 and 2 zeros in 300, so 3+2 = 5 zeros total.
So this estimation technique allows you to multiply large numbers like this very quickly without needing a calculator or pencil/paper.
Since 6397 rounded down, and 349 rounded down too, this means the result of 1,800,000 is an underestimate of the true value which is
6,397 x 349 = 2,232,553
The estimate isn't too far off.
Find the value of p and q such that 2x² - 4x + 3 = 2(x-p)²+q
Answer:
q= 4xp - 2p² - 4x + 3
p=
Step-by-step explanation:
2x² - 4x + 3 = (x -p) + q
OPEN BRACKET:
2x² - 4x + 3 = 2(x² - 2xp + p²) + q
2x² - 4x + 3 = 2x² - 4xp + 2p² + q
-4x + 3= 4xp + 2p² + q
-q = -4xp + 2p² + 4x - 3
q = 4xp - 2p² - 4x + 3
Based only on the information given in the diagram, which congruence
theorems or postulates could be given as reasons why Hij is congruent to klm
Answer:
C. HA
D. AAS
Step-by-step explanation:
∆HIJ is a right triangle with a given labelled acute angle and a given hypotenuse, which are congruent to the acute angle and hypotenuse length of ∆KLM, by on the Hypotenuse-Acute Angle Theorem (HA), ∆HIJ and ∆KLM are congruent.
Also, the two triangles have two given angles that are congruent, and a non-included side (hypotenuse), which are congruent in both triangles, by definition of the AAS congruency theorem, both triangles can be said to be congruent.
Therefore, the congruency theorems that could be given as reasons why both triangles are congruent to each other are the HA and AAS theorems.
Answer:
The correct answer is HA and AAS.
Step-by-step explanation:
The HA (hypotenuse angle) states "if the hypotenuse and one acute angle of a right triangle are congruent to the hypotenuse an done acute angle of another triangle, then the triangles are congruent.
The AAS (angle-angle-side) theorem states "If two angles and a non-included side of one triangle are congruent to two angles and a non-included side of a second triangle, then the triangles are congruent.
