Jada walks up to a tank of water that can hold up to 15 gallons. When it is active, a drain empties water from the tank at a constant rate. When Jada first sees the tank, it contains 12 gallons of water. Five minutes later, the tank contains 10 gallons of water.

Type your answers in the blanks below.

At what rate is the amount of water in the tank changing? Use a signed number, and include the unit of measurement in your answer.


How many more minutes will it take for the tank to drain completely?

________minutes

How many minutes before Jada arrived was the water take completely full?

_________ minutes

Answers

Answer 1

Answer:

A) -2/5 gal/min

B) 25 minutes

C) 7.5 minutes

Step-by-step explanation:

A) We are told that the tank contains 12 gallons of water when Jada first sees it.

5 minutes later, it loses two gallons to become 10 gallons.

Thus, rate at which the amount of water in the tank changing = -2/5 gal/min

B) After 5 minutes it contains 10 gallons. Since it drains at 2/5 gal/min, let us say the time to finish draining all is x, thus;

2/5 • x = 10

x = 10 × 5/2

x = 25 minutes

C) When full, it can hold up to 15 gallons. This is 3 more than the 12 she saw when she arrived.

Thus;

2/5 • y = 3

y = 5 × 3/2

y = 7.5 minutes

Isaac finished eight of the ten homework problems. Phil has finished of the homework. How many more problems did Isaac finish?​

Answers

Answer:

-2

Step-by-step explanation:

If Issac has finished 8/10 problems in the homework, and Phil has completed all of it, it can be concluded that Phil completed 10/10. 10/10 would equal a whole, or in this case, the entire homework. If Issac completed 8 problems, and Phil completed 10, subtract both values to find that Issac completed -2 more problems than Phil.

__m²
Composite made up of a rectangular prism surmounted by a triangular prism. The rectangular prism has dimensions of 16 meters wide by 20 meters long by 12 meters high. The triangular prism has dimensions of 16 meters wide by 20 meters long with a triangular altitude of 8 meters high.

Answers

SEE THE IMAGE BELOW (I REALLY HOPE THIS IS CORRECT!!!)

Answer:

1764 m²

Step-by-step explanation:

Refer to attached picture.

All given dimensions are given on the picture (not to scale).

Since altitude of the triangle and slant height is given, we can find the base of the triangle using Pythagorean:

[tex]b/2 = \sqrt{11.3^2-8^2} = \sqrt{64} = 8m, \\b = 16 m[/tex]

It has 9 faces and the total surface area is:

S = 16*20 + 2(20*12) + 2(20*11.3) + 2(16*12) + 2(1/2*8*16)  = 1764 m²

Answers

Answer:

The answers are A, B and C.

Step-by-step explanation:

To solve the inequality you first have to use Distributive Property. You should get -3k + (-21) > -57

Next Divide 21 on both sides. -57/21 is -36

You should have -3k > -57

Divide -3 on both sides. -57/-3 is 12

You should end up with k > 12

And you never used -5, 0 or 8 in the equation and the question asks to choose the following that isn't included in the solution so your answers are A, B and C.

Answer:

x=6

Step-by-step explanation:

x+54+5x=90

6x+54=90

6x=36

x=6

Answer:

x=6

Step-by-step explanation:

So, lets go over what we know.

Angle 5x and angle x+54 make up 90 degrees.

We know its 90 degrees since there is a square like symbol on the side of the line.

To sovle for x, we must add the two angles together. This will make them equivelent to 90 degrees.

So:

5x+x+54=90

=

6x+54

Now that we combined our two angles, we can solve it like a normal equation:

6x+54=90

subtract 54 from both sides to get 6x alone:

6x=36

Now divide both sides by 6 so x is alone:

x=6

So now we know that x=6.

If you wan to check your answer, just look at the orginal graph, plug in 8 for x, and see if the two angles add up to 90:

Angle 5x:

5*6

=

30

Angle x+54

6+54

=

60

Add the two angles together:

30+60

=

90

So we have checked and the answer is still correct!

Hope this helps! :D

You roll a six-sided number cube and flip a coin what is the probability of rolling a number greater than 3 and flipping heads? Write your answer as a fraction in simplest form.​

Answers

Answer:

1/4

Step-by-step explanation:

Possible outcomes from rolling the cube that satisfy the "greater than 3" criterion are {4, 5, 6}  out of a total of six possibilities {1, 2, 3, 4, 5, 6}.  Thus, the probability of rolling a number greater than 3 is 3/6, or 1/2.

Probability of flipping heads is 1/2.

These are entirely independent events.  Thus, the joint probability is (1/2)(1/2), or 1/4.

Area  = πr²

By putting the value, we get

Area = (22/7) × 4²

=  22/7 × 16

= 352÷16

Area = 22in²

In a right triangle, the hypotenuse has endpoints P(–3, 2) and Q(1, –3). If R represents the third vertex in the triangle and R is located in the third quadrant, what is the length of PR?

Answers

Answer:

PR = 5 units.

Step-by-step explanation:

Given:

Right triangle

Hypotenuse = P(–3, 2), Q(1, –3)

R = located in the third quadrant.

To calculate the length of PR,

(i) First make a sketch of the points P and Q. The diagram is attached to this response.

(ii) As shown in the diagram, the point R is located in the third quadrant and its distance from P is from point -3 to 2 on the y-axis.

There are 5 points between -3 and 2. Therefore, the length PR = 5 units

Answers

Answer:

d

Step-by-step explanation:

not a bc it has to be negative

not c bc its has to be negative

not b bc the slope is -1/2

IT'S D

Answer:

D

Step-by-step explanation:

from the picture, we know that the slope is negative to begin, since the line is going on a downward direction from left to right. this eliminated A and C instantly.

Now we also can see the graph crossed at 3 for the y intercept, which is another reason to eliminate A and C.

we must then find the show of the line.

let us use to point (0,3) since this is the y intercept and (6,0) since this is the x intercept. to find the slope, m, at must use the equation

[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]

so, let's label (0,3) as point 1 and (6,0) as point two. then,

x1 = 0

y1= 3

and

x2= 6

y2=0

Now we just plug in and simplify.

[tex] m = \frac{0 - 3}{6 - 0} = \frac{ - 3}{6} = - \frac{1}{2} [/tex]

we now have our slope and y intercept, so we can plug them into our equation

[tex]y = mx + b[/tex]

where m is the slope and b is the y intercept.

our equation is thus

[tex]y = - \frac{1}{2} x + 3[/tex]

so, the answer is D

Sally can paint a room in 9 hours while it takes Steve 5 hours to paint the same room. How long would it take them to paint the room if they worked​ together?

Answers

Answer: About 3 hours and 5 minutes to paint the room together.

Step-by-step explanation:

Sally can paint 1/5 of the room in an hour and Steve can paint 1/8 of the room in an hour.

Room/Hour

1/5 ± 1/8 =8/40  

8/40+5/40=13/40

How long to paint the room?

13/40 x 1= 40/13

40÷13=3.0777

So the answer will be Sally and Steve can paint the room in about 3 hours and 5 minutes

Greg uses a triangular area of his back yard as a garden.If the area if his garden 1.248 square feet,whats the area of the garden?

Answers

Answer:

192 ft²

Step-by-step explanation:

Area of rectangular backyard = 1248 ft²

Width of backyard = 52 ft

Length = x

Area of rectangular backyard = Length * width

1248 = x * 52

x = 1248 / 52

x = 24 feets

Hence, x = height of triangular garden

Area of triangle = 1/2 base * height

Area = 1/2 * 16 * 24

Area = 192 ft²

Alice is searching online for tickets to a knicks game. Two weeks ago, the cost was $30. Now the cost is $39. What is the percent increase

Answers

Given:

Two weeks ago, the cost of tickets = $30

Now, the cost of tickets = $39

To find:

The percent increase.

Solution:

We have,

Initial value = $30

New value = $39

Formula for percentage increase is:

[tex]\%\text{increase}=\dfrac{\text{New value - Initial value}}{\text{Initial value}}\times 100[/tex]

Using this formula, we get

[tex]\%\text{increase}=\dfrac{39-30}{30}\times 100[/tex]

[tex]\%\text{increase}=\dfrac{9}{3}\times 10[/tex]

[tex]\%\text{increase}=3\times 10[/tex]

[tex]\%\text{increase}=30[/tex]

Therefore, the percent increase in the cost of tickets is 30%.

Answers

Answer:

$37500

Step-by-step explanation:

Given data

Width of side walk= 5ft

Lenght= 250ft

Cost per square foot= $30

Hence the area of the side walk= 5*250

                                                     = 1250ft^2

Hence the cost = 30*1250

                            =$37500
