Answer:

To drain the water tower it will take 36 hours.

Step-by-step explanation:

Given:

A 72,000 water tower is being drained, and in an hour 2000 gallons are drained.

Now, to calculate the hours it would take to drain total 72,000 gallons of water, we should divide the gallons of water drained in one hour by total gallons of water in the tower.

Gallons of total water in the tower ÷ Gallons of water drained per hour

72000\div 2000

=\ 36

Therefore, to drain the water tower it will take 36 hours.

Which of the following functions is graphed below?
dalvyx [7]

Answer:

The function graphed is y = Ix - 5I - 4 ⇒ answer D

Step-by-step explanation:

* Lets explain how to solve this problem

- From the graph

# The graph intersects the x-axis at x = 1 and x = 9

∴ The x-intercepts are 1 and 9

- We can find x-intercept by equate y by 0

* Lets equate the answers by zero to find the x-intercept

# y = Ix + 5I - 4

∵ Ix + 5I - 4 = 0

- Add 4 to both sides

∴ Ix + 5I = 4

- Remember in Ia + bI = c, then we have two answers :

 a + b = c  <em>OR </em> a + b = -c

∵ Ix + 5I = 4

∴ x + 5 = 4 ⇒ subtract 5 from both sides

∴ x = -1

- OR

∴ x + 5 = -4 ⇒ subtract 5 from both sides

∴ x = -9

∴ The x-intercepts are -1 and -9 not the same with figure

# y = Ix - 5I + 4

∵ Ix - 5I + 4 = 0

- Subtract 4 from both sides

∴ Ix - 5I = -4

- Remember in Ia + bI = c , c can't be negative because the absolute

 value is always positive

∴ We can't solve this equation

# y = Ix + 5I + 4

∵ Ix + 5I + 4 = 0

- Subtract 4 from both sides

∴ Ix + 5I = -4

- Remember in Ia + bI = c , c can't be negative because the absolute

 value is always positive

∴ We can't solve this equation

# y = Ix - 5I - 4

∵ Ix - 5I - 4 = 0

- Add 4 to both sides

∴ Ix - 5I = 4

- Remember in Ia + bI = c, then we have two answers :

 a + b = c  <em>OR </em> a + b = -c

∵ Ix - 5I = 4

∴ x - 5 = 4 ⇒ add 5 to both sides

∴ x = 9

- OR

∴ x - 5 = -4 ⇒ add 5 to both sides

∴ x = 1

∴ The x-intercepts are 1 and 9 the same with figure

* The function graphed is y = Ix - 5I - 4

Charlie is watching hot air balloons. Balloon A has risen at a 60° angle. Balloon B has risen at an 82° angle. If the distance f
babymother [125]

Answer:

(B)1005 feet

Step-by-step explanation:

In the attached diagram

\angle y =82^\circ\\\angle x =60^\circ

|AG|=1400 feet

Distance from point C to point G=|CG|

Using Trigonometry in Triangle ACG

\tan 60^\circ=\dfrac{1400}{CG}\\ CG=\dfrac{1400}{\tan 60^\circ}\\\approx 808$ feet

Using Trigonometry in Triangle BCG'

\tan 82^\circ=\dfrac{1400}{CG'}\\ CG'=\dfrac{1400}{\tan 82^\circ}\\\approx 197$ feet

Therefore, the distance from balloon B from balloon A

=CG+CG'

=808+197

=1005 feet

sergey [27]

9514 1404 393

Answer:

  2r(20r +60) = 80r^2

Step-by-step explanation:

Anna's first investment:

  20

Anna's first return:

  20r

Anna's second investment:

  20r +60

Anna's second return:

  r(20r +60)

__

Hannah's first investment:

  80

Hannah's first return, and her second investment:

  80r

Hannah's second return:

  80r^2

__

Twice Anna's return was equal to Hannah's return:

  2r(20r +60) = 80r^2

June made a design with 6 equal tiles.One tile is yellow 2 tiles are blue and 3 tiles are purple. what fraction of the tiles are
lana66690 [7]

we know that

The fraction of each tile color can be found by dividing the number of tiles for each tile by the total number of tiles, then simplifying the fraction if possible.

Let

N----------> total number of tiles

Y---------> number of yellow tiles

B--------> number of blue tiles

P--------> number of purple tiles

we have

N=6\\ Y=1\\ B=2\\ P=3

<u>1) Find the fraction of yellow tiles</u>

we know that

the fraction of yellow tiles is equal to

Y/N

substitute the values

1/6

<u>2) Find the fraction of purple tiles</u>

we know that

the fraction of purple tiles is equal to

P/N

substitute the values

3/6

<u>3) Find the fraction of yellow tiles or purple tiles</u>

we know that

the fraction of yellow tiles or purple tiles is equal to

(Y/N)+(P/N)=(1/6)+(3/6)=4/6=2/3

therefore

<u>the answer is</u>

2/3

Maria has already written 2/5 of her 1,000 word essay. If she continues writing at the same pace of 6One-half words per minute,
ella [17]

Answer:

~ 92.31 minutes

Step-by-step explanation:

Given:

Length of essay = 1000

Essay already written = \frac{2}{5} of the total essay

OR

Essay already written = \frac{2}{5} \times 1000  =400\ words

Essay remaining = Length of essay - Essay already written

Essay remaining = 1000 - 400 = 600 words

i.e. \frac{3}{5} of the total essay is remaining which is actually equal to 600 words.

6.5 words are written in = 1 minute

1 word is written in = \frac{1}{6.5} minutes

600 words are written in = \frac{1}{6.5}\times 600\ minutes   = \bold{92.31}\ minutes
