Mimi uses a 7.5-gal bucket to fill a wading pool. She pours 12 buckets full of water into the pool, which can hold up to 138 gal of water. She wants to solve for n, the number of additional full buckets of water she can pour into the pool.
Answers
Answer: 6 full buckets.
Step-by-step explanation:
138(pool)/7.5(a bucket)=18.4
18-12=6 full buckets.
A community swimming pool has a deep end and a shallow end. The volume of water in the deep end can be represented by (2x2+12x+10) ft3 and the volume of the water in the shallow end can be represented by (4x2−100)ft3.
Write the equivalent expression ("simplified") that represents the total volume of the water in the pool in ft3.
Answers
Answer:
The total volume of water in the pool = ( 6x^3 + 12x^2 - 90x ) ft^3
Step-by-step explanation:
The volume of water in the deep end = (2x^3 + 12x2 + 10x) ft^3
The volume of water in the shallow = (4x^3 -100x) ft^3
The total volume of water in the pool = (2x^3 + 12x2 + 10x) + 4x^3 -100x)
= ( 6x^3 + 12x^2 - 90x ) ft^3

2.)
6y = -36
y = -6
-4x+12 = -12

x = 6
solution: (6,-6)
Answer:
Top: x=1, y= -2
Bottom: x= 6, y= -6
Step-by-step explanation:
Top:
Isolate x for y: 2(3+y) + y = 0
Simplify: 6+3y=0
Isolate y for 6+3y=0: y = -2
For x= 3 + y: x = 1
Bottom:
Isolate x for : -4x - 2y= -12: x= [tex]\frac{-6 + y}{2}[/tex]
Simplify: 6y+ 12 = -24
Isolate y for 6y+ 12 = -24: y = -6
For x= [tex]-\frac{-6 -6 }{2} = 6[/tex] : x = 6

The mean absolute deviation of this data set is 1.25 which is nearest to the 1.1 option third is correct.
What is mean absolute deviation?It is defined as the measure to show the variation in data set in other words between the mean and every data value, the distance known as the MAD.
We have data as shown in the picture in the form of frequency graph.
The mean = 11/4 = 2.75
The difference between each value and mean is shown in the attached table.
MAD = 5/4 = 1.25
The nearest value is 1.1.
Thus, the mean absolute deviation of this data set is 1.25 which is nearest to the 1.1 option third is correct.

The representation of Brian's situation in slope intercept form is:
y= 15x +70
Step-by-step explanation:
Let x be the number of weeks Brian started his collection.
y be the number of cards Brian has at present.
y= 45+25+ 15 x
