Step-by-step explanation:
The distributive property is as follows :
[tex]a(b+c)=ab+ac[/tex] ....(1)
We need to solve [tex]24(\dfrac{d}{4}-5)=156[/tex] using distributive property
Applying property (1) on the LHS of given equation
Taking a = 24, b = d/4 and c = -5
So,
[tex]24(\dfrac{d}{4}+(-5))=156\\\\24\times \dfrac{d}{4}+24\times (-5)=156\\\\6d-120=156\\\\6d=156+120\\\\6d=276\\\\d=\dfrac{276}{6}\\\\d=46[/tex]
So, we get the value of d as 6 using distributive property.

A 50 litre solution of acid and water contains 10 litres of acid. How much water must be added to make the solution 8 % acidic. Will mark brainest to whoever answers.
Answer:
Your welcome!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
You are descending from the top of a 32-foot tall rock climbing wall at an average rate of -2.3 feet per minute. How many feet off the floor are you in 5 minutes? How many feet off the floor are you in 10 minutes? Approximately when will you reach the ground?
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.

f(x)=-4x-6 and g(x)=3x+5. Find (f o g)(-3) plzzzzzzzzzzz helpppppppp
Answer:
(f o g)(-3) = 10Step-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

Suppose a social networking site has roughly 1,000,000 users, and as each
member signs up for an account, he or she is assigned a number. Which of these would result in the largest sample size using systematic sampling?
A. Surveying every 25,000th number
B. Surveying every 25th number
C. Surveying every 250th number
D. Surveying every 2,500th number.
The option that results in the largest sample size using systematic sampling is; Surveying every 25,000th number
How to find the Sample Size?
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:

Student’s Answer
A. y= 9200x+1400; 10,600 lbs
B. y= 5000x+1400; 21,400 lbs
C. y= 1400x+ 5000; 10,600 lbs
D. y= 5000 +41400; 21,400 lbs
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.
What is the slope of the line?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)

|3 - 3|
|-19 - (-8)|
|3 + (-19)|
|3 - (-8)|
| 3 + (-19) |
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

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.
