Sam wants to know how long it will take to fill his baby pool that holds 24 gallons. After 1 minute, there are 2 gallons of water in the pool. He plots the points (0,0) and (1,2) on his coordinate plane. What is the x-value of the point (x, 24)?
Answer:
(12,24)Step-by-step explanation:
Givens
The pool holds 24 gallons.The rate is 2 gallons of water per minute.The line that represents the problem passes through points (0,0) and (1,2).We can deduct the equation that represents this problem using the point-slope formula
[tex]y-y_{1} =m(x-x_{1} )\\y-2=2(x-1)\\y=2x-2+2\\y=2x[/tex]
So, for [tex]y=24[/tex], we have
[tex]y=2x\\24=2x\\x=\frac{24}{2}\\ x=12[/tex]
Therefore, after 12 minutes there were 24 gallons of water in the pool. The right answer is (12,24).

Find the percent of the total area under the standard normal curve between the given z-scores. z= -1.10 and z= -0.36
To find the percent between two z-scores under the standard normal curve, subtract the individual areas. In this case, the percentage between z = -1.10 and z = -0.36 is 1.72%.
To find the percent of the total area under the standard normal curve between z-scores, you need to first calculate the difference between the two areas to the left of each z-score. Given that the area to the left of z = -1.10 is 0.3446 and the area to the left of z = -0.36 is 0.3618, you can find the percent between them by subtracting these values: 0.3618 - 0.3446 = 0.0172 or 1.72%.

Answer:
y-5=-1/2(x+3)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(4-5)/(-1-(-3))
m=-1/(-1+3)
m=-1/2
y-y1=m(x-x1)
y-5=-1/2(x-(-3))
y-5=-1/2(x+3)

The height of four boys measured 152.0 cm. 150.75 cm,149.5 cm, and 149.25 cm. Bradley is the tallest, Calvin is taller than Josh, but shorter than Mark. Josh is the shortest. What is Mark's height
Answer:
150.75 cm
Step-by-step explanation:
Given heights,
152.0 cm, 150.75 cm, 149.5 cm, and 149.25,
∵ Calvin is taller than Josh, but shorter than Mark,
The increasing order of heights,
Josh < Calvin < Mark,
Also, Bradley is the tallest,
That is, the height of Bradley is the greater than Josh, Calvin and Mark,
So, the final increasing order of heights,
Josh < Calvin < Mark < Bradley
∵ 149.25 < 149.5 < 150.75 < 152.0
Hence, the height of Mark is 150.75.
Drag the numbers to order them from least to greatest.
Answer:
-4 1/2, -1/2, 1/4, 2/3, 2 1/3
Step-by-step explanation:
Given the numbers in the order below;
-1/2, 1/4,2/3,-4 1/2, 2 1/3
Firstly we will convert this fractions to percentage.
For -1/2;
-1/2×100 = -50%
For 1/4;
1/4×100 = 25%
For 2/3;
2/3×100 = 66.7%
For -4 1/2 = -9/2
-9/2×100 = -450%
For 2 1/3 = 7/3
7/3×100 = 233.1%
Ordering the numbers from least to greatest means arranging from lowest to highest(ascending order of magnitude)
During arrangement, the negative values are the least and that come first followed by the positive values. The arrangements gives;
-450%, -50%, 25%, 66.7%, 233.1%
According to their fractions will give us;
-4 1/2, -1/2, 1/4, 2/3, 2 1/3 (From lowest to greatest)
After a car is purchased, the value of a new car decreases $4000 each year. After 3 years, the car is worth $18000.
Write an equation that represents the value V (in dollars) of the car x years after it is purchased.
Answer:
Original - 4000x
so, after 3 years we have:
Original - 12000 = 18000

Solve for y in terms of x 2/3y-4=x
Answer:
y = 3/2x + 6
Step-by-step explanation:

2/3y = x + 4
y = 3/2(x) + 4*3/2
y = 3/2x + 6
hence the answer is y = 3/2x + 6

How do you find and use the greatest common factor of two whole numbers
The greatest common factor of two whole numbers can be found by an example given.
How to find Greatest common factor?Greatest common factor, as the name implies, is greatest among all common factors among the quantities given.
We can factorize the quantities in smallest relative factors possible (one level of factors over which all quantities can form themselves), and collect as many common factors as we could. Those would be together compose as GCF(Greatest common factor).
For example;
we have the 52, and 24, for a number that can go into both that is the largest possible for my example
That would be 4 since, no number greater can go into both, while 2 would be a option it would not be the greatest.

Brittany had 7 rolls of quarters and four extra quarters. She use the equation n = 7q + 4 to n, the number of quarter she had all together. What equation could she use to find q, the number of quarters in each roll?
Brittany can use the equation q = (n - 4) / 7 to find the number of quarters in each roll, based on the total number of quarters she has.
To find the equation that Brittany could use to determine the number of quarters in each roll (q), we can rearrange the original equation to solve for q. Given the equation n = 7q + 4, where n represents the total number of quarters she had, we can solve for q as follows:
n - 4 = 7q, by subtracting 4 from both sides of the equation.
Then, we divide both sides by 7 to isolate q:
q = (n - 4) / 7.
This equation can be used by Brittany to determine the number of quarters in each roll based on the total number of quarters she possesses. It essentially divides the total number of quarters minus the extra quarters by the number of rolls to give the quantity of quarters in each roll.

The cubs won 87 games in 2013 and 75 games in 2014. Find the percent decrease?
To find the percent decrease between the number of games won by the Cubs in 2013 and 2014, subtract the two numbers and calculate the percentage.
Explanation:To find the percent decrease, we need to calculate the difference between the two numbers and then calculate what percentage that difference is of the original number. In this case, the initial number of games won by the Cubs in 2013 was 87, and the number of games won in 2014 was 75. The difference is 87 - 75 = 12. To calculate the percent decrease, divide the difference by the original number and multiply by 100: (12 / 87) * 100 = 13.79%. Therefore, the percent decrease is approximately 13.79%.
