Step-by-step explanation:
La piscina llena tendra 600.000 litros de agua.Para el tratamiento inicial hay que añadir 10 gramos de cloro por cada 1.000 litros de agua.Si el cloro se vende en botes de 1 kilo.¿cuantos botes necesitaran Sara y sus abuelos?
Answer:
Sara y sus abuelos necesitarán 6 botes.
Step-by-step explanation:
Primero, tienes que encontrar los gramos de cloro que necesitas para 600.000 litros de agua usando una regla de tres dado que sabes que se debe añadir 10 gr de cloro por cada 1.000 litros de agua:
1.000 litros → 10 gr
600.000 litros → x
x=(600.000*10)/1.000=6.000 gr de cloro
Ahora, tienes que encontrar a cuántos kg equivalen los 6.000 gr de cloro que necesitas teniendo en cuenta que 1 kg son 1.000 gr:
1 kg → 1.000 gr
x ← 6.000 gr
x=(6.000*1)/1.000= 6 kg
Finalmente, para saber cuántos botes se necesitan tienes que dividir los 6 kg entre 1 kg porque el cloro se vende en botes 1 kg:
6/1=6
De acuerdo a esto, Sara y sus abuelos necesitarán 6 botes.

The shoes were $175. They are now 10% off. How much are they now?
Sale Price = $157.5 (answer). This means the cost of the item to you is $157.5. You will pay $157.5 for a item with original price of $175 when discounted 10%. In this example, if you buy an item at $175 with 10% discount, you will pay 175 - 17.5 = 157.50 dollars.
Hope this helps!
Evaluate 4 cubed. I will mark brainlest.
Answer:
64
Step-by-step explanation:
4 cubed is 64 because 4 cubed can be written as an exponentiation, where the base is 4 and the exponent is 3, like this: 43. For future reference, note that cubed means that the exponent is 3 regardless of what the base is. When the exponent is 3 (aka cubed) and the base is 4 you simply multiply 4 by 4 by 4 to get the answer 64

Step-by-step explanation:
Answer: y = 50; x = 34
ABCD is a quadrilateral inscribed in the circle
=> ∠ABD = ∠ACD
⇔ x = 34°
and ∠ADB = ∠ACB
we also have:
∠DCE + ∠ DCB = 180°
⇔ 96° + x + ∠ACB = 180°
⇔ ∠ACB = 180 - 96 - x = 180 - 96 - 34 = 50
because ∠ADB = ∠ACB => y = 50°

Polygon MNP shown on the coordinate planeA dilation centered about the origin will be performed on the polygon with vertices M(- 18, 12) forall(8,10),8(-6,8) and Q(- 8, - 8)
Answer:
N'(4, 5)
Step-by-step explanation:
The correct question is attached.
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, dilation and translation.
Dilation is a transformation that changes the size of a figure (i.e. it increases or reduces the size).
If a point A(x, y) is dilated by a factor k, the new point is at A'(kx, ky).
The location of the polygon vertex is at M(-16, 12), N(8, 10), P(-6, 8) and Q(-8, -8).
After dilation, the new location of M is at M'(-8, 6)
M(-16, 12) ⇒ M'(-8, 6)
M(-16, 12) ⇒ M'[1/2(-16), 1/2(12)]
Hence the dilation factor is 1/2. This means that the new vertex is at:
N'(4, 5), P'(-3, 4) and Q'(-4, -4).

A linear regression equation is computed for a sample of n = 13 pairs of X and Y scores. For the analysis of regression testing the significance of the equation, what are the df values for the F-ratio?
Answer:
The degrees of freedom are
ν₁ = n₁ -1 = 13 -1 = 12
ν₂= n₂-1 = 13 -1 =12
Step-by-step explanation:
Step(i):-
Given size 'n' = 13
size of sample of X score n₁ = 13
size of sample of Y score n₂ = 13
The degrees of freedom are
ν₁ = n₁ -1 = 13 -1 = 12
ν₂= n₂-1 = 13 -1 =12

How many solutions does the equation below have.
*The answer choices are below*
==========================================
Work Shown:
2(b+3)-17 = 3b-7+b
2b+6-17 = 4b-7
2b-11 = 4b-7
-11+7 = 4b-2b
-4 = 2b
2b = -4
b = -4/2
b = -2
There is one solution and it is b = -2
A quick way to tell we have one solution is to note that both sides are a linear expression, and that the slopes of each linear expression are different values. If you had two lines with the same slope, then you'd have either parallel lines or coinciding lines (leading to no solutions and infinitely many solutions respectively). When you have two lines with two different slopes, then they are guaranteed to intersect only once. That intersection point is the solution.
Answer:
The answer is one solution
Step-by-step explanation:
1)2(b+3)-17 = 3b-7+b
2)2b+6-17 = 4b-7
3)2b-11 = 4b-7
4)-11+7 = 4b-2b
5)-4 = 2b
6)2b = -4
7)b = -4/2
Final your answer is b = -2

Answer:
I mean we don’t have to use the net becuase there is a shape right there already so the answer is 280 m for SA
Step-by-step explanation:
So find 5*6 first aAnd you’d get 30
30*2 becuase there are 2 sides, 60
10*6 is 60
60*2 is 120
5*10 is 50
50*2 is 100
now add them all up
you’d get 280 inches :)

Alexus is modeling the growth of bacteria for an experiment in science. She assumes that there are B bacteria in a Petri dish at 12:00 noon. In reality, each bacterium in the Petri dish subdivides into two new bacteria approximately every 20 minutes. However, for the purposes of the model, Alexus assumes that each bacterium subdivides into two new bacteria exactly every 20 minutes.
2a. Create a table that shows the total number of bacteria in the Petri dish at 1/3 hour intervals for 2 hours starting with time 0 to represent 12:00 noon.
2b. Write an equation that describes the relationship between total number of bacteria T and time h in hours, assuming there are B bacteria in the Petri dish at h=0.
2c.If Alexus starts with 100 bacteria in the Petri dish, draw a graph that displays the total number of bacteria with respect to time from 12:00 noon (h=0) to 4:00 p.m. (h=4). Label points on your graph at time h=0,1,2,3,4.
2d. For her experiment, Alexus plans to add an anti-bacterial chemical to the Petri dish at 4:00 p.m. that is supposed to kill 99.9% of the bacteria instantaneously. If she started with 100 bacteria at 12:00 noon, how many live bacteria might Alexus expect to find in the Petri dish right after she adds the anti-bacterial chemical?
