The three Miller boys were calculating the volume of their new fish tank to determine how many gallons of water the tank can hold. Each brother measured a different dimension of the tank. Their measurements were 1 yard in length, 1 foot in width, and 18 inches in height.

1. There are approximately 7.5 gallons per cubic foot. If you want to know how many gallons of water the tank can hold, what unit of measure would you use to calculate the volume of the fish tank? Explain why

2. Determine how many gallons of water the fish tank can hold. Carefully show your work and include units of measure.

Answer:

ft33.75 gal

Step-by-step explanation:

1. The conversion factor is given in gallons per cubic foot. So, to avoid more conversion factors than necessary, it is convenient to use feet as the unit of measure.

2. The dimensions are ...

1 yd × 3 ft/yd = 3 ft . . . . length

18 in × 1 ft/(12 in) = 1.5 ft . . . . height

So, the volume is ...

V = LWH = (3 ft)(1 ft)(1.5 f) = 4.5 ft³

Then the number of gallons is ...

(4.5 ft³)×(7.5 gal/ft³) = 33.75 gal

PLEASE HELP ,,,,1. If AMNP is an equilateral triangle, find the values of x
and y.

Answers

An equilateral triangle is a triangle in which all three sides have the same length[tex].[/tex]

⭆ 14 = 3x - 4

⭆ 3x = 14 + 4

⭆ 3x = 18

⭆ x = 18/3

⭆ x = 6

In equilateral triangle, all three internal angles are also same and each are of 60°.

⭆ 5y - 5 = 60

⭆ 5y = 60 + 5

⭆ 5y = 65

⭆ y = 65/5

⭆ y = 13

★ Final answer :

x = 6y = 13Hope It Helps!

Answer:

x = 6y = 13

Step-by-step explanation:

equilateral triangle, all sides are equal,

MN = MP

14 = 3x - 4

x = 18/3

x = 6

internal angles are also equal.

5y - 5 = 60 (180/3 = 60)

5y = 65

y = 13

I need help finding the values of x and y!!

Answers

Answer:

x= 22

y = 35

Step-by-step explanation:

The base angles of a isosceles triangle are equal

3x-11 = 2x+11

Subtract 2x from each side

3x-2x -11 = 2x-2x+11

x-11 = 11

Add 11 to each side

x-11+11 = 11+11

x = 22

The sum of all the angles in a triangle is 180

3x -11 + 2x+11 + 2y = 180

Combine like terms

5x +2y = 180

5*22 + 2y = 180

110 + 2y = 180

Subtract 110 from each side

110+2y-110 = 180-110

2y = 70

Divide by 2

2y/2 =70/2

y = 35

To round 35.367 to the nearest tenth consider the hundredths’ value of 35.367, which is 6 and equal or more than 5. Therefore, the tenths value of 35.367 increases by 1 to 4.

35.367 rounded to the nearest tenth = 35.4

What in slope-intercept form, can go through the line ( a, 2a) and (-5a, 6a)

Answers

Answer:

y = -2/3x + 8/3a

Step-by-step explanation:

Given points

(a, 2a) and (-5a, 6a)

Slope-intercept form

y = mx + b

Slope of the line is

m = (6a - 2a)/( -5a - a) = 4a/(-6a) = - 2/3

The y-intercept is:

2a = -2/3*a + bb = 2a + 2/3ab= 8/3a

So the line is:

y = -2/3x + 8/3a

Answer:

y = -2/3 - 8/3a

Step-by-step explanation:

Find the slope using [ y2-y1/x2-x1 ]

6a-2a/-5a-a

4a/-6a

-2/3

Find the y-intercept.

y = mx + b

y = -2/3x + b

2a = -2/3(a) + b

-8/3a = b

y = -2/3 - 8/3a
