Answer:
Lemon juice / water = 12,5 / 47,5 or 26,31 %
Step-by-step explanation:
First step:
We got 60 liters. of water and we replace 15 liters. of water and add 15 liters of lemon juice, then our mixture is:
60 lts. of mixture ⇒ with 45 lts. is water and 15 lts. is lemon juice
The proportion of the mixture
each liter of the mixture is 0,75 lts. of water and 0,25 of lemon juice
2 step
Removing 10 lts. of mixture implies
10 lts of mixture means 7,5 lts. of water and 2,5 lts. of lemon juice
then we have
50 lts. of mixture with (45 - 7,5 = 37,5 lts.) of water and (15 - 2,5 = 12,5 ) lts. of lemon juice
third step
Addind 10 lts. of water:
60 lts. of mixture with ( 37,5 + 10 = 47,5) lts. of water and 12,5 lts. of lemon juice
Final mixture is
60 lts. of mixture with 47,5 lts. of water and 12,5 lts. of lemon juice
Proportion
Lemon juice / water = 12,5 / 47,5 or 26,32 %
If one penny, two dimes, and one quarter are added to the bag, what is the new probability that Marissa will draw a nickel? Write your answer as a fraction, as a decimal, and as a percent. 25% chance. (I gave all info please answer this:
In which situation is it more likely that Marissa will draw a nickel
Answer:
As a fraction it's ¼, as a decimal it's 0.25 and as a percentage it's 25%
Answer:
= 1/5
.2
20%
Step-by-step explanation:
In the bag there are 5 pennies, 4 nickels , 5 dimes, 2 quarters
We add 1 penny 2 dimes and 1 quarter
Now in the bag
6 pennies, 4 nickels, 7 dimes, 3 quarters
for a total of 20 coins
P ( nickel) = number of nickels / total
= 4/20 = 1/5
.2
20%
She is more likely to draw a nickel before the 1 penny 2 dimes and 1 quarter because there are fewer coins in the bag that are not nickels

To rent a certain vehicle, Rent-A-Ride charges $55.00 per day with unlimited miles. The cost of renting a similar vehicle at We Got Wheels is $38.00 per day plus $0.20 per mile. For what number of miles is the cost at Rent-A-Ride less than the cost at We Got Wheels?
Given :
Rent-A-Ride charges $55.00 per day with unlimited miles. The cost of renting a similar vehicle at We Got Wheels is $38.00 per day plus $0.20 per mile.
To Find :
For what number of miles is the cost at Rent-A-Ride less than the cost at We Got Wheels.
Solution :
Let, after x miles Rent-A-Ride charges is less than the cost at We Got Wheels.
Price at Got Wheels > Price at Rent-A-Ride
38 + 0.20x > 50
0.20x > 12
x > 60
Therefore, after 60 days cost at Rent-A-Ride less than the cost at We Got Wheels.
Hence, this is the required solution.

4 cachorros se terminan un paquete de croquetas en 6 días, si tuviéramos 3 cachorros ¿cuantos días duraría el paquete ?
Answer:
4 1/2 días.
Step-by-step explanation:
En la pregunta se nos dice que:
4 cachorros terminarán un paquete de croquetas en 6 días, si tuviéramos 3 cachorros, ¿cuántos días duraría el paquete?
4 cachorros = 6 días
3 cachorros = y días
Cruz multiplicar
4 cachorros × y = 3 cachorros × 6 días
y = 3 cachorros × 6 días / 4 cachorros
y = 18/4
y = 4 2/4
y = 4 1/2 días
Por lo tanto, el paquete de croquetas para 3 cachorros tendrá una duración de 4 1/2 días.
What is the arc measure for WX
X=10 btw
Answer:
106°
Step-by-step explanation:
The intercepted arc is double the measure of the inscribed angle intercepting it. Each of the angles V and Y is 53°, so arc WX is 2×53° = 106°.

triangle abc with vertices a(-3 2) b(-1 7) and c(6 1) in the x-axis
Answer:
A'(-3, -2), B'(-1, -7), C'(6, -1)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. If an object is transformed, all its points are also transformed. Types of transformation are reflection, rotation, dilation and translation
If a point X(x, y) is reflected across the x axis, the new location is X'(x, -y).
If triangle ABC is reflected across the x axis, the new vertices are A'(-3, -2), B'(-1, -7), C'(6, -1)

What is the image point of (4,5) after a translation left 5 units and down 3 units?
Answer:
(-1,2)
Step-by-step explanation:
Going left means the x value goes down. In this case, it went to the left 5 spaces. so, all you have to do is subtract 5 from 4 which is -1. When going down on a graph, the y value goes down as well. Subtract 3 from 5 and you get 2. Therefore, the answer is (-1, 2).

Alina is 6 years older than Greg. Amy’s age is 2.5 times Alina's age. Amy is 40. How old is Greg?
A. 16
B.10
C. 15
D.10
Answer:
Hi friend! The answer is D. 10
I hope this helps!
Answer:
B) 10
Step-by-step explanation:
Assign variables to each person:
A=Alina's Age
M=Amy's Age
G=Greg's Age
Set up a system of equations given the information:
A=6+G
M=2.5A
M=40
Notice that M is already given, so we can plug that into the second equation:
40=2.5A
16=A
So Alina is 16 years old, but the problem asks for Greg's age, so we plug Alina's age in the first equation:
16=6+G
10=G
So Greg is 10 years old, therefore B is the correct answer.

what solution does the equation |4x+7|=-3 have
The result of an absolute value function is never negative. This is because absolute value represents distance on a number line, and negative distance is not possible. Negative distance doesn't make sense.
So we don't have solutions to something like |x| = -5 or the given equation. The right hand side must be 0 or a positive number if you want to have at least one solution.
