Answer:

Step-by-step explanation:

Acid present in the solution = 10 L

Required volume concentration of acid = 8/100

Let x amount of water be added to achieve the required %.

In the new solution, proportion of acid= 10/(50+x)

Therefore,

10/(50+x) = 8/100

x=75

Ans: 75 L of water must be added to the solution

Answer:

| - 19 - (- 8) |

Step-by-step explanation:

Given that the 2 points have the same x- coordinate, then the distance between the 2 points is the difference in the y- coordinates, that is

distance = | - 19 - (- 8) | = | - 19 + 8 | = | - 11 | = 11

Or

distance = | - 8 - (- 19) | = | - 8 + 19 | = | 11 | = 11

Answer:

C

Step-by-step explanation:

The slope is 1400. And the y intercept is 5000 because when x=0 y=5000. And if you multiply 1400 by 4 and then add 5000 you get 10,600 lbs for the weight at 4 weeks.

The slope is 1400 and the y-intercept is 5000 of the linear equation which is the correct answer would be option (C) y = 1400x + 5000; 10,600 lbs.

The slope of the line is defined as the angle of the line. It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

Consider two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)

We have to determine the slope and y-intercept of the linear equation that models this data,

Week       Weight (lbs)

0                 5000

1                 6400

2                 7800

3                 9200

Slope  = (7800 - 6400)/(2 - 1) = 1400

There is a 1400 slope.

And since y=5000 for x=0, the y-intercept is 5000.

So the equation of a baby whale’s weight at 4 weeks is y = 1400x + 5000

Hence, the correct answer would be option (C)

Answer:

Step-by-step explanation:

f(x) = - 4x - 6

g(x)=3x+5

To find (f o g)(-3) we must first find

(f o g)(x)

To find (f o g)(x) substitute g(x) into f(x) that's for every x in f (x) replace it with g (x)

That's

(f o g)(x) = - 4( 3x + 5) - 6

= - 12x - 20 - 6

(f o g)(x)= - 12x - 26

Now to find (f o g)(-3) substitute the value of x that's - 3 into (f o g)(x) and solve

We have

(f o g)(-3) = - 12(-3) - 26

= 36 - 26

We have the final answer as

(f o g)(-3) = 10

Answer:

You are 11.5  feet off the floor are you in 5 minutes

You are 23  feet off the floor are you in 10 minutes

it will take 13.91 minutes to reach the ground

Step-by-step explanation:

If   you are top , height will keep decreasing as you move downward.

Given

top height 32 feet

Descending speed = -2.3 feet /minute

Here negative sign implies that height is decreasing.

concept used

distance = speed * time

How many feet off the floor are you in 5 minutes?

time = 5 minutes

distance descended = -2.3 feet /minute*5 minutes = - 11.5 feet

Hence ,

I would have moved 11.5 feet from the top.

Distance from ground will be = Top height - distance descended

Distance from ground will be = 32 - 11.5 = 20.5 feet

____________________________________________

How many feet off the floor are you in 10 minutes

distance descended = -2.3 feet /minute*10 minutes = - 23 feet

Hence ,

I would have moved 23 feet from the top.

Distance from ground will be = Top height - distance descended

Distance from ground will be = 32 - 23= 9 feet

______________________________________________

When you reach the ground distance descended will be 32 feet.

Since its a descend distance off the floor has to be taken as negative value

Thus, distance descend in this case will be -32 feet

-32 feet= -2.3 feet /minute*Time

Time = -32/-2.3 = 13. 91 minutes.

Thus, it will take 13.91 minutes to reach the ground.

Hey there! I'm happy to help!

If something is symmetrical you can cut a line through it and it will be the same on both sides. If you have a perfect circle you can cut it in half and it will be the same on both sides, so it is symmetrical.

We see that W looks the same on both sides if you cut it in half at the 3. It is the same on both sides, so the answer is W.

Answer:

Y

Step-by-step explanation:

The option that results in the largest sample size using systematic sampling is;  Surveying every 25,000th number

If the numbers of people are assigned in order of 1 to 1,000,000 then the smallest sample would be obtained by conducting surveys every 25 000th numbers.

The calculation of the sample size would be made by dividing 1, 000,000 by 25000.

1,000,000/25000 = 40

Therefore, the smallest sample selected would be 40 people.

If the surveys were made every 25th numbers, then the sample size would be:
