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)?
Answers
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).
Round 0.955 inches to the nearest tenth of an inch

_____________________________________________________
"1.0 inch" ; (or, write as: "1.0 in." ; or even: "1.0 inches" .) .
____________________________________________________
Given: "0.995 inches" ; round to the nearest TENTH of an inch.
(which means; round to the nearest "first decimal point" ; and to include the actual first decimal point (and that decimal point only, the "tenths place").
We are given the number: "0.955" . This is given to the nearest THOUSANDS.
We examine the "tenths place": "0.9" . So we know our choices are:
"0.9" (round down to the nearest tenths place); or, "1.0" (round up to the nearest tenths place).

The answer is: 1.0 inches.
______________________________________________________
The nearest tenth is the first digit after the decimal point. The round 0.955 inches to the nearest tenth of an inch is 1.0 inches.
Given 0.995 inches
round to the nearest tenth of an inch.
This means round to the nearest first decimal point and to include the actual first decimal point (and that decimal point only, the tenth place).

We examine the tenth place at 0.9.
So we know our choices are
What is the nearest tenth?The nearest tenth is the first digit after the decimal point.
0.9 (round down to the nearest tenths place) or 1.0 (round up to the nearest tenths place).
We examine the number 0.955 and look to the next value, the hundredths place
If that digit is 5 or greater we round up and the correct answer is 1.0.
If that number is 4 or less (i.e. 0 to 4), we round down and the correct answer is 0.9.
In the case of our give value: 0.955.
The digit to the right of 9 is 5 so, as previously mentioned,
we round up to 1.0.
Therefore, The round 0.955 inches to the nearest tenth of an inch is 1.0 inches.
The answer is 1.0 inches.

Marcus sorts his 85 baseballs cards into stacks of 9 cards each. How many stacks of 9 cards Marcus make
Answers
To get your answer, you must divide:
85/9 = 9.4
So, Marcus made 9.4 stacks of cards.
I really hope you found this helpful! :)
Marcus can make 9 full stacks.
To determine how many stacks Marcus can make, we need to perform a division of the total number of baseball cards by the number of cards per stack.
Total number of baseball cards: 85.
85 ÷ 9.
= 9 (with a remainder of 4.)
This means Marcus can make 9 full stacks of 9 cards each with 4 cards left over.

At 2:30 am the temperature in Joelle is 3 F. The temperature drops 3/4 of a degree in 30 min. What is the temperature on Joelle at 3:00am?
Answers
Answer: B. [tex]=2.25^{\circ}F[/tex]
Step-by-step explanation:
Given: At 2:30 am the temperature in Joelle is 3 F.
The temperature drops 3/4 of a degree in 30 min.
3/4 of a degree= [tex]\frac{3}{4}\times1^{\circ}F=\frac{3}{4}=0.75^{\circ}F[/tex]
Therefore, the temperature on Joelle after 30 min= [tex]3^{\circ}F-\frac{3}{4}\ of\ 1^{\circ}F[/tex]
[tex]=3^{\circ}F-0.75^{\circ}F[/tex]
[tex]=2.25^{\circ}F[/tex]
Thus, the temperature on Joelle at 3:00am=[tex]=2.25^{\circ}F[/tex]

OF bisects EOF. EOF=y+30 and FOG=3y-50. solve for y.
Answers
It always helps to draw a picture. Given the information, Segment OF is the center line that is bisecting this angle.
Since it's bisecting (cutting in half)... we can simply set the two angles equal to each other.
y+30=3y-50
-2y+30=-50
-2y=-80
y = 40
C)40.
Setting the given equations equal to each other, we can solve for y and determine that y equals 40.
Explanation:The question states that OF bisects EOF, which means that EOF and FOG are equal. Hence, you can set the two equations equal to each other to solve for y.
EOF = y + 30FOG = 3y - 50Set EOF equal to FOG:
y + 30 = 3y - 50
To solve for y, first simplify the equation by subtracting y from both sides:
30 = 2y - 50
Then add 50 to both sides to isolate the y variable on one side:
80 = 2y
Finally, divide both sides by 2 to solve for y:
y = 40

Find the percent of the total area under the standard normal curve between the given z-scores. z= -1.10 and z= -0.36
Answers
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%.

Answers
Independent variable = age
Dependent variable = height
"depends on age" indicates that age is independent.
-----------------------------------
Part (b)
Independent variable = amount of sleep
Dependent variable = mood
The key word is "determines". The stuff before this word is the independent variable which affects the dependent variable.
-----------------------------------
Part (c)
Independent variable = time water has been running
dependent variable = amount of water in the tub
Time is usually the independent variable
-----------------------------------
Part (d)
Independent variable = speed
dependent variable = distance from home
-----------------------------------
Part (e)
Independent variable = amount of homework done
dependent variable = speed
This seems like an odd pairing of homework and speed. Could there be a typo? I noticed that part (f) is very similar
-----------------------------------
Part (f)
Independent variable = amount of hw that is assigned
dependent variable = amount of homework done
