(50 points) Here are descriptions of four situations in which the volume of water in a tank is
a function of time. Match each description to a corresponding graph. Each graph
is used only once.

Situation A: An empty 20-gallon water tank is filled at a constant rate for 3
minutes until it is half full. Then, it is emptied at a constant rate for 3 minutes.
Situation B: A full 10-gallon water tank is drained for 30 seconds, until it is half
full. Afterwards, it gets refilled.
Situation C: A 2,000-gallon water tank starts out empty. It is being filled for 5
hours, slowly at first, and faster later.
Situation D: An empty 100-gallon water tank is filled in 50 minutes. Then, a dog
jumps in and splashes around for 10 minutes, letting 7 gallons of water out. The
tank is refilled afterwards.

c = 5

therefore the solpe = 5

Answer:

5/6

Step-by-step explanation:

Answer:

The answer is 113.

Answer:

141

Step-by-step explanation:

There are 8 nines: 9×8=72

There are 3 sevens: 7×3=21

There are 4 eights: 8×4=32

6×2=12

2×2=4

All together you get

Step-by-step explanation:

Solution

(s) = 100m

(t) = 72.54s

(v) = ??

We have,

v = s÷t

v = 100 ÷ 72.54

v = 1.37 m/s

Hence, the velocity of the swimmer is 1.37 m/s

Answer:

62 cm²

Step-by-step explanation:

The surface area (SA) is the sum of the areas of the 6 faces.

The opposite faces are congruent, then

SA = area of front/ back + area of top/ bottom + area of 2 sides

     = 2(5 × 3) + 2(5 × 2) + 2(3 × 2)

     = 2(15) + 2(10) + 2(6)

     = 30 + 20 + 12

     = 62 cm²

Answer:

1. -1/2

2. Graph attached below:

Step-by-step explanation:

1) To find to slope of the line with two points would be the following equation:

[tex]y_{2} - y_{1} / x_{2} - x_{1}[/tex]

So let’s assume our variables and subsitute them to see that the Carma’s Working out is an error.

Form: [tex](x_{2}, y_{2}), (x_{1}, y_{1})[/tex]

[tex]y_{2} = 3[/tex]

[tex]y_{1} = 1[/tex]

[tex]x_{2} = 7[/tex]

[tex]x_{1} = 11[/tex]

[tex]3 - 1 / 7 - 11 = -1/2[/tex]

1. Error one: The point values of the slope aren‘t correctly labeled and are not the same form as in the formula.

2. Error two: The slope output is not correct, it is 2 but the slope is -1/2.

Now let’s get on the graph of Carma’s workout, I can spot that the point (-4, 5) is not plotted correctly. Instead it is plotted (4, -5). To understand clearly I will label these points on a graph, image attached below:

3. Error three: The point (-4, 5) is not plotted correctly, x should be negative and y should be positive.

4. Error four: The slope is not correct, instead the slope of the graph is negative but we need a positive slope.

Now it is time to fix Carma’s mistakes:

1) Slope: -1/2

2) Graph attached below

77.82 $ will be paid at physical Store

Step-by-step explanation:

Item                 Quantity          Physical Store Online Store

Headphones 1 pair                 $14.99/ea             $13.50/ea

DVDs             4 DVDs             $13.95/ea             $14.99/ea

CDs               2 CDs                $9.85/ea              $10.99/ea

Cost Price = 14.99 + 4 * 13.95  + 2 * 9.85

= 90.49 $

20% off Coupon = (20/100)90.49  = 18.1 $

Amount after Coupon = 72.39 $

7.5% sales Tax = (7.5/100)72.39 =  5.43$

Amount with Tax = 72.39 + 5.43  = 77.82 $

77.82 $ will be paid at physical Store

Answer:

y = - 3x + 7

Step-by-step explanation:

( 2 , 1 )

( 5 , - 8 )

m = ( - 8 - 1 ) / ( 5 - 2 ) = - 3

y - 1 = - 3 ( x - 2 )

y = - 3x + 7

Answer: (-1, 7) should be the answer

Step-by-step explanation:

why did you copy my profile picture hello......

y = -2x + 24

hope this is helpful!

Answer:

y+2x=24

Step-by-step explanation:

the equation of the line: y=1/2x -9

Get the slope by using derivative:

dy/dx= 1/2

dy/dx= slope of the normal line

Since we are looking for slope of the tangent line:

Use Mn=-1/Mt

The slope of the tangent line is -2

Using point slope form:

(y-y1)=m(x-x1) ; where x1=7, y1=10, and m=-2

y-10=-2(x-7)

y-10=-2x+14

ANSWER: y+2x=24

Answer:

C. 2:5

Step-by-step explanation:

You can divide both side of the ratio 20:50 by 5 which leaves you with 4:10. You can simplify it again by dividing it by 2 and get 2:5

Answer:

Distributive Property

Step-by-step explanation:

5(x - 7) = 55   ⇒   5x - 35 = 55

The 5 was distributed in 5(x-7) to get 5x - 35.

Answer:

it's AAS is my opinion

Step-by-step explanation:

Answer:

AAS

Step-by-step explanation:

we can eliminate two of the answer choices from the start. AA and SSA do not prove triangle congruence. we are then left with SAS and AAS. we can see that there is one pair of sides and one pair of angles marked congruent on the triangles. the triangles are formed by intersecting lines which form vertical angles. according to the vertical angles theorem, those two angles will be congruent. therefore, these triangles are proven congruent by AAS. hope this helps!
