Step-by-step explanation:
The new dolphin tank at the city aquarium is in the shape of a rectangular prism. It is long by wide by deep. To make the tank livable for the dolphins, the aquarium workers treat the water using bags of salt. The amount of water a bag of salt can treat is known in cubic feet.
(a) Find the volume of water in the tank in cubic feet.
(b) To make the tank livable for the dolphins, a bag of salt must be added for each 19.4ft$ of water. The aquarium doesn't have any salt on hand and the salt can only be purchased in whole bags. How many bags of salt must be purchased to treat the water?
(c) If each bag of salt costs $4.85, how much must the aquarium pay for salt to treat all the water in the new dolphin tank?
answer quickly
The volume of water in the tank is 35,100 cubic feet.
What is the volume of the rectangular prism?Volume = length × width × height
We have the following parameters based on the information provided;
Length = 20 meters
Width = 13 meters
Height = 5 meters
Substitute the values into the formula to get
Volume = 20 × 13 × 5
Volume = 1300 cubic meters
Convert the cubic yard into cubic feet
1 cubic yard = 27 cubic foot
⇒ 1300 yards = x
⇒ x = 27 × 1300
⇒ x = 35,100 cubic feet
Therefore, the amount of water a bag of salt can treat is 35,100 cubic feet

10x÷8=18
plz helppppppppppppppppppppppppppppppppppp
Hey there!
10x ÷ 8 = 18
MULTIPLY 8 to BOTH SIDES
10x ÷ 8 * 8 = 18 * 8
SIMPLIFY IT
NEW EQUATION: 10x = 144
DIVIDE 10 to BOTH SIDES
10x/10 = 144/10
CANCEL out: 10/10 because it gives you 1
KEEP: 144/10 because it helps simplify for the x-value
x = 144/10
x = 144 ÷ 2/10 ÷ 2
x = 72/5
Therefore, your answer is: x = 72/5
Good luck on your assignment and enjoy your day!

Write the equation of the line that has a slope of 4/5 and a y-intercept of -8.
The equation of any staright line can be written as y = mx + c , where m is its slope and c is its y - intercept . hence, equation of line with slope = 4/5 and y - intercept = -8 is,
→ y = 4/5x - 8
→ m - c = 4/5 + 8 = 12/5

The value of 2√5 x 5√5 is 50.
What is Radical?The √ symbol that is used to denote square root or nth roots. Radical Expression - A radical expression is an expression containing a square root.
An expression that uses a root, such as a square root, cube root is known as a radical notation.
Given:
2√5 x 5√5
So, Multiplying the roots
= 2√5 x 5√5
= ( 2x 5) ( √5 x √5)
= 10 x 5
= 50
hence, the multiplication of Radical gives 50.

find the intersection of the two lines by solving the system of equations please help I will give brainliest
Answer:
(-3, -5)
Step-by-step explanation:
We can add the two equations together so the x's cancel out:
x + y = -8
-x + y = -2
2y = -10
y = -5
We can substitute y in to get x:
x - 5 = -8
x = -3
This means the intersection is (-3, -5).

Ralph painted 1/6 of a wall in 2/3 hour. At this rate how many hours will it take Ralph to paint the whole wall?
Answer:
4 hours
Step-by-step explanation:
1/6 is one segment
6 segments make a whole
6/6 = 1
2/3 is equal to one segment
2/3 * 6 = 4
Answer:
It will take 4 hours.
Step-by-step explanation:
Let the size of whole wall be x.
Given that
Ralph painted 1/6 of a wall in 2/3 hours
thus, writing it in mathematical form we have,
time taken to pain 1/6 of x = 2/3 hours
=time taken to pain x/6 wall = 2/3 hours
since, we have taken size as x so to find time to pain x size of wall ,
we divide both side by 6
=time taken to pain x/6 * 6 wall = 2/3 *6 hours
= time taken to paint x wall = 4 hours

The difference between twice one number and a lesser number is 32. The sum of the lesser number and twice the greater is 60. Find the numbers
Answer:
The numbers are 23 , 14
Step-by-step explanation:
Let the greater number = x
The smaller number = y
2x - y = 32 ------------(I)
2x + y = 60 ----------------(II)
Add the two equations. Thus y will be eliminated and we can find the value of x
(I) 2x - y = 32
(II) 2x + y = 60 {Now, add}
4x = 92
x = 92/4
x = 23
Plugin x = 23 in equation (II)
2*23 + y = 60
46 + y = 60
y = 60 - 46
y = 14
The numbers are 23 , 14

P'(-2,5) is the image of P after a dilation centered at the origin with a
scale factor of 1/3. What are the coordinates of P?
Explanation:
When going from the preimage P to its image P', we multiply each coordinate by the scale factor 1/3.
To go in reverse (image to preimage), we multiply by the reciprocal of that scale factor. The reciprocal of 1/3 is 3/1 or simply 3.
Triple the coordinates of (-2, 5) to end up with (-6, 15)
We can check the answer by multiplying each coordinate of (-6, 15) by the original scale factor 1/3 and you should end up with (-2, 5) again.

D.x>-1
Answer:
D.
Step-by-step explanation:
We are given
9(x/3 + 1) >= 6
Divide 9 on both sides
x/3 + 1 >= 2/3
Subtract 1 on both sides
x/3 >= -1/3
Multiply 3 on both sides
x >= -1
