For Pool A, the water level is dropping 2.5 inches per hour. For Pool B, the water level increases 2.5 inches per hour. Starting water levels are shown. Pool A: 60 inches Pool B: 20 inches When will the pools have the same water level? Write an equation and solve. Enter the correct answers in the boxes. Equation: h=what. The pools will have the same water level after hours. Σ
Answer:
8 hours
Step-by-step explanation:
60 - 2.5x = 20 + 2.5x
40 = 5x
8 = x
60 - (2.5 x 8) = 40
20 + (2.5 x 8) = 40

and please be quick
Answer:
steps below
Step-by-step explanation:
3+2y = 2+4y
2y = 1
y = 1/2
Is it correct?
Answer:
On the left side, there are two large weights of mass y and three small weights of mass 1. Represent this side with the expression 2y + 3.
On the right side, there are four large weights of mass y and two small weights of mass 1. Represent this side with the expression 4y + 2.
The scale is balanced, so there is equal weight on each side. We can describe the relationship between the weight on each side of the scale using the equation 2y + 3 = 4y + 2.

2. How many circles of radius 1 unit can you fit inside a circle of radius 3 units so that they
do not overlap?
3 circles of radius 1 unit can you fit inside a circle of radius 3 units so that they do not overlap
What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
Given,
A circle of radius 3 units.
We need to find how many circles of radius 1 unit can you fit inside a circle of radius 3 units.
A radius of 1 unit means that the diameter is 2 units.
A radius of 3 units means that the diameter is 6 units.
To find this we have to divide 6 by 2
Six divided by 2 which is equal to three
6/2 = 3
So 3 circles can fit inside a circle with a radius of 3 units
Hence, 3 circles can fit inside a circle with a radius of 3 units

Solve the equation p^2 - 4p = 10 by completing the square
Answer:
Step-by-step explanation:
p² - 4p = 10
add the square of half of the "b" value to each side of the equation
b/2 = -4/2 = -2
-2² = 4
p² - 4p + 4 = 10 + 4
p² - 4p + 4 = 14
(p - 2)(p - 2) = 14
(p - 2)² = 14
p - 2 = √14
p = 2 + √14

Which statement describes the graph
Answer:
D. The graph crosses the y-axis at (0, 5), increasing from x = -10 to x = 2 and remaining constant from x = 2 to x = 10.
Step-by-step explanation:
For this case, the first thing you should observe is that you have a different function in two distinct intervals.
We have then:
For [-10, 2]:
The linear function has a positive slope, therefore it grows and cuts the y-axis at the point (0, 5)
For [2, 10]:
We have a constant function whose equation is:
y = 5

Please solve and give answer
Answer:
y=-2x+2
Step-by-step explanation:
slope intercept formula: y=mx+b
if were finding the slope intercept form we need to take 4x to the other side making the equation:

we cant have a coefficient with y so we divide the whole inequality by 2 to eliminate 2 making our answer:
y=-2x+2

Find the value of x that makes m ∥ n.
Answer:
x = 60Step-by-step explanation:
Corresponding angles must be same to make the lines m and n parallel.
2x + 15 = 1352x = 120x = 60Answer:
x = 60
Step-by-step explanation:
1. First of all, we must know that these angles are corresponding. That means they're congruent in angle measures.
2. Given the information above, 2x + 15 = 135.
3. (Solving)
Step 1: Subtract 15 from both sides.
[tex]2x + 15 - 15 = 135 - 15[/tex] [tex]2x = 120[/tex]Step 2: Divide both sides by 2.
[tex]\frac{2x}{2} = \frac{120}{2}[/tex] [tex]x = 60[/tex]Step 3: Check if solution is correct.
[tex]2(60)+15=135[/tex] [tex]120 + 15 = 135[/tex] [tex]135 = 135[/tex]Therefore, x = 60.
A certain group of women has a 0.94% rate of red/green color blindness. If a woman is randomly selected, what is the probability that she does not have red/green
color blindness?
Answer:
99.06%
Step-by-step explanation:
100.00% - 0.94% = 99.06%
Probability that a randomly selected woman does not have red/green color blindness: 99.06%
Color blindness is a condition that affects the ability to distinguish certain colors, most commonly red and green. In this problem, we are given that a certain group of women has a 0.94% rate of red/green color blindness.
Let's define the probability of having red/green color blindness as P(R), and the probability of not having red/green color blindness as P(~R). The sum of these two probabilities should equal 1, as a woman either has the condition or does not.
Step 1: Calculate the probability of having red/green color blindness (P(R)):
P(R) = 0.94% = 0.0094 (as a decimal)
Step 2: Calculate the probability of not having red/green color blindness (P(~R)):
P(~R) = 1 - P(R)
P(~R) = 1 - 0.0094
P(~R) = 0.9906 (as a decimal)
Step 3: Convert the probability to a percentage:
P(~R) = 0.9906 * 100%
P(~R) ≈ 99.06%
So, the probability that a randomly selected woman does not have red/green color blindness is approximately 99.06%.
In summary, this means that in the given group of women, about 99.06% of them do not have red/green color blindness, while approximately 0.94% do have this condition.

This claim seems a bit fast and you want to put him to the test, so you make him run a mile. He runs the mile in 5.8 minutes, which is slower than his claim. However, if he is telling the truth, there is about a 0.31 probability, of having a time at least as high as 5.8 minutes.

En la fabricación de un automóvil, se requiere pintarlo, secarlo y pulirlo. La compañía Motores Épsilon produce tres tipos de automóviles: el Delta, el Beta y el Sigma. Cada Delta necesita 10 horas de pintado, 3 horas de secado y 2 horas de pulido. Un Beta necesita 16 horas de pintado, 5 horas de secado y 3 horas de pulido, mientras que un Sigma necesita 8 horas de pintado, 2 horas de secado y 1 hora de pulido. Si la compañía dispone de 240 horas para pintado, 69 horas para secado y 41 horas para pulido al mes ¿Cuántos automóviles de cada tipo produce?
Answer: s=10 b=5 d=8
Step-by-step explanation:Sus tres variables son d, b, s que representan respectivamente el número de Deltas, Betas y Sigmas.
Para configurar el sistema de ecuaciones, sume el número de horas tarea por tarea. La primera ecuación será solo para la cantidad de horas dedicadas a pintar, la segunda para secar y la tercera para pulir.
La primera ecuación: cada modelo tiene una cantidad diferente de horas dedicadas a la pintura. Multiplique esa cantidad de horas por la cantidad de autos de ese modelo (sus variables d, bo c) para obtener la cantidad total de horas dedicadas a pintar todos los autos de ese modelo. Luego, ajústelo al número total de horas que la empresa pasó pintando.
10d + 16b + 8s = 240
Repita para la segunda y tercera ecuaciones y debería obtener:
10d + 16b + 8s = 240
3d + 5b + 2s = 69
2d + 3b + 1s = 41
