it in a closed container. Mrs. Smith draws a card in the morning and replaces it and repeats the process at the end of
the day. What is the probability that the same student will have his/her name drawn both times in the same day?

Answer:

Answer:

B.1,536

Explanation:

length x width x height = v

12 x 8 x height = 96 x height

12 x 8 x 16 = 1536 or v

Answer:

y=3x

Step-by-step explanation:

if you look 3*3=9   5*3=15 8*3=24 and 10*3=30 so they are taking x*3

Answer:

Y=3x

Step-by-step explanation:

The way a function table works is how x has something done to it to equal y. So if x =4, and y=16

You could formulate the equation y= 4x.

So if we look at the patterns

3 to 9

5 to 15

8 to 24

10 to 30

Y is equal to x times 3.

3(x)·3=9(y)

3(x)=y

3x=y

The equation would be 3x=y

The expression represent the value of v is :[tex]v=\sqrt{z(w+z)}[/tex]

The correct option is D

We have the attachment.

As shown, when deconstructing the largest right triangle, we got two similar triangles.

The corresponding sides of similar are proportional. Therefore, we can write the following proportion:

v/ w+ z = z/v

By Cross - multiply, we get:

z(w + z) = [tex]v^2[/tex]

And taking the square root of both sides, we get:

[tex]v=\sqrt{z(w+z)}[/tex]

So, The correct option is D

The storage tank requires an additional 4,640 gallons of water to be filled to the top, calculated by finding the total tank capacity using the 20% already filled and subtracting the current water volume.

The student asks about the amount of water needed to fill a storage tank to the top given that the tank is already 20% full with 1,160 gallons of water. To find out how much more water is required, we first need to establish the total capacity of the tank.

Since 1,160 gallons represent 20% of the tank's capacity, we can calculate the full capacity by dividing the amount of water currently in the tank by 0.2. After finding that number, we need to subtract 1,160 from the total capacity to find the amount of water needed to fill the tank.

Calculation:

1. Calculate the full capacity of the tank:
Total capacity = 1,160 gallons / 0.20 = 5,800 gallons.

2. Calculate the gallons of water needed to fill the tank:
Gallons needed = Total capacity - Current amount of water
Gallons needed = 5,800 gallons - 1,160 gallons = 4,640 gallons.

Therefore, 4,640 gallons of water are needed to fill the storage tank to the top.

Answer:

22

Step-by-step explanation:

f(x)=5x-3

f(x)=5(5)-3

f(x)=25-3

f(x)=22

Answer:

[tex]f(5)=22[/tex]

Step-by-step explanation:

since the function is f(x), then you would plug in the 5 since that is x value that is being given then it would be [tex]f(5)=5(5)-3[/tex]. from there multiply 5 and 5 to get 25 then subtract 3 to get 22.

Answer:

40 milliliters of the 10% solution and 80 milliliters of the 25% solution the scientist should mix to make the 20% solution.

Step-by-step explanation:

Given:

A scientist needs 120 ML of a 20% acid solution for an experiment. The lab has available at 10% solution and a 25% solution.

Now, to find the milliliters of 10% solution and 25% solution to make 20% solution:

Let the 10% solution be [tex]x.[/tex]

And let the 25% solution be [tex]y.[/tex]

So, total milliliters of solution are:

[tex]x+y=120\\\\x=120-y\ \ \ \ .....(1)[/tex]

Now, to get the milliliters of 10% solution and 25% solution to make 20% solution we solve the equation:

[tex]10\%\ of\ x+25\%\ of\ y=20\%\ of\ 120\\\\\frac{10}{100} \times x+\frac{25}{100} \times y=\frac{20}{100} \times 120\\\\0.10x+0.25y=24[/tex]

Substituting the value of [tex]x[/tex] from equation (1) we get:

[tex]0.10(120-y)+0.25y=24\\\\12-0.10y+0.25y=24\\\\12+0.15y=24[/tex]

Subtracting both sides by 12 we get:

[tex]0.15y=12[/tex]

Dividing both sides by 0.15 we get:

[tex]y=80.[/tex]

Thus, the 25% solution is 80 ml.

Now, substituting the value of [tex]y[/tex] in equation (1) we get:

[tex]x=120-y\\\\x=120-80\\\\x=40\ ml.[/tex]

Hence, the 10% solution is 40 ml.

Therefore, 40 milliliters of the 10% solution and 80 milliliters of the 25% solution the scientist should mix to make the 20% solution.

Answer:

-2/9

Step-by-step explanation:

The slope is found by

m= (y2-y1)/(x2-x1)

   = (-12- -14)/(3-12)

    =(-12+14)/(3-12)

    =2/-9

   = -2/9

Answer: x= -2,y=6

Step-by-step explanation:

4x+y= -2......equation 1

3x+2y=6.....equ2

Y= -2-4x........equation 3

Substitute equation 3 into 2

3x+2(-2-4x)=6

Open the bracket

3x+(-4-8x)=6

3x-4-8x=6

3x-8x=6+4

-5x=10

X= 10/-5

X= -2

Substitute for x in equation 1

4x+y= -2

4(-2)+y= -2

-8+y= -2

Y= -2+8

Y=6

Therefore, x= -2 & y=6

Answer:

9/25x

Step-by-step explanation:

3/5/x ×12/20

3/5×1/x ×12/20

36/100x

Divide both by 4

9/25x

The exact value of x cannot be determined because we don't know what the equation is equated to

So we will have to leave the answer as 9/25x

 4/5 X 10=8 because

[tex]\frac{4}{5}[/tex]  X [tex]\frac{10}{1}[/tex]  -->we do the denominator first so 5 x 1 = 5 so now it's

[tex]\frac{4}{5}[/tex] [tex]\frac{10}{5}[/tex] so 4 X 10= 2 x 5(we replace 10 with that ) over 5  and the you will be left with 4 x 2 over 5  that is because 5 and 5 canceled out so

now  you're left with this 4 x 2 = 8 so 8 is you final answer without the fraction :) hope this helps

Answer:

Step-by-step explanation:

Answer:

30 = 9x + 7

Step-by-step explanation:

The total weight of the bundle = 30 pounds

The weight of the bricks = x pounds

But he carried 9 bricks = 9x pounds

He also carried additional 7 pounds of concrete block.

An equation to show the total weight he carried is

30 pounds = (9x + 7) pounds

Since 9x represents the total weight of the bricks he carried

7 represents the weight of the concrete block

And 30 pounds represents the total weight of everything he carried.

Answer:

D

Step-by-step explanation:

I did the work its D on edge.

To simplify the given expression, we first simplify the fraction within the square root, performing the division of similar bases by subtracting exponents. Then, we take the square root of 64 to get 8 and obtain the final simplified expression: 8/x^2y.

To solve the specific expression, equivalent to StartRoot StartFraction 128 x Superscript 5 Baseline y Superscript 6 Baseline Over 2 x Superscript 7 Baseline y Superscript 5 Baseline EndFraction EndRoot, we will start by simplification inside the square root bracket. Perform the division with the fractions first. As a general rule, when dividing powers with the same base, we subtract the powers.

We'll start by simplifying 128/2, which is 64. For x Superscript 5 Baseline / x Superscript 7 Baseline, subtract the exponents, which gives us x to the power of -2 (since 5-7 is -2). For y Superscript 6 Baseline / y Superscript 5 Baseline, we also subtract the exponents, which results in y to the power of 1, or simply y.

Hence, the simplified version of the fraction inside the square root is 64x^-2y. Finally, since the square root of 64 is 8, and the square root of any variable raised to the negative power is the reciprocal of the variable, our final simplified expression is 8/x^2y.
