Jada walks up to a tank of water that can hold up to 15 gallons. When It is activated, a drain empties water from the tank at a constant rate. When Jada first sees the tank it contains 12 gallons of water. Four minutes later, the tank contains 9 gallons of water.

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


B.) How many more minutes will it take for this tank to drain completely? Explain or show your reasoning


C.) How many minutes before Jada arrived was the tank completely full? Explain or show you reasoning.

Answer:

No, Noah's method does not always work.

Step-by-step explanation:

Let's say we're trying to find 40% of 80 instead of 20% of 60.

If we divide 80 by 5, like Noah says, we get 16, which is not 40% of 80.

The proper solution would be to multiply the number by the percentage converted to a decimal.

In this case, it would be 80 × 0.4, which is 32.

When you try to solve 20% of 60, you can say 60 × 0.2, which also gets 16.

Answer:

No it doesn't

Step-by-step explanation:

His method never works because multiplying by does not give the same result as dividing by 5. AI Recommended Answer: To find 20% of a number, divide the number by 5. For example, 20% of 60 is 12.

Answer:

The sum of the angles in a triangle must be 180°, while 80+40+40 only gives us 160°.

Answer:

(1/30π) x 6 cm = 0.06283185 x 6 cm = 0.376 cm.

Step-by-step explanation:

The distance travelled by the tip of the second hand of a clock in 1 minute, if the hand is 6 cm long, is approximately 3.6 degrees or approximately 0.06283185 radians. This is because the circumference of a complete circle is equal to 2π radians, and a clock face is divided into 60 equal parts, so each part is equal to 1/60 of 2π or 1/30π radians. To convert this to cm, you can multiply by the length of the second hand, which is 6 cm. Therefore, the distance travelled is (1/30π) x 6 cm = 0.06283185 x 6 cm = 0.376 cm.

Answer:

2.25

Step-by-step explanation:

15.00

-12.75

-----------

2.25

The simplest way to subtract 15 - 12.75 is (14 + 1) - (12 + 0.75) and it will be 2.25.

To subtract in mathematics is to take something away from a group or a number of objects.

In other meaning, subtraction is a mathematical operation such that two values are going to subtract and give a resultant value.

As per the given,

15 - 12.75

⇒ (14 + 1) - (12 + 0.75)

Open bracket

14 + 1 - 12 - 0.75

14 - 12 + 1 - 0.75

2 + 0.25 = 2.25

Hence "The simplest way to subtract 15 - 12.75 is (14 + 1) - (12 + 0.75) and it will be 2.25".

Answer:

5/6 more meters

Step-by-step explanation:

Find the perimeter of the wardrobe (Add all the sides together) and you get 4 5/6 m.

Subtract 4 meters because she already has 4 meters of ribbon.

4 5/6 - 4 = 5/6

Answer:

Step-by-step explanation:

P = (2/3)*2 + (7/4)*2                      (1 3/4 = 7/4)

4/3 + 14/4

= 16/12 + 42/12

= 58/12

= 29/6

= 4 5/6

She already has 4 m of ribbon

4 5/6 - 4 = 5/6 m or ribbon needed

Assign the numbers to the number line in the following order:

2.15=2.15

220%=2.2

9/4=2.25

*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:

2.15, 2.2, 2.25

Answer:

y=-4/3+3

Step-by-step explanation:

To find this equation in slope-intercept form you must first put it into point-slope form. Remember point-slope is \(y-y_{2}=m(x-x_{2})\) so plugin the points and slope to get \(y-7=-4/3(x+3)\). Then solve the equation for y.

First, distribute the -4/3

y-7= -4/3x-4

Then, add 7 to both sides

y=-4/3+3

Answer:

y=-4/3x+3

Step-by-step explanation:

y-7=-4/3(x-(-3))

y-7=-4/3x-4

y=-4/3x+3

Answer:

-17

Step-by-step explanation:

I will represent the question mark with the variable \(x\).

\(x - 11 + 12 = -16\)

To solve for \(x\), we need to isolate it.

To do this, subtract 12 from both sides.

\(x - 11 + 12= -16\\\underline{\textrm{ } \ \ \ \ \ \ \ \, -12} \ \, \, \, \, \ \underline{-12}\\x - 11 \ \ \ \ \ \: \ = -28\)

Then, add 11 to both sides.

\(x - 11 = -28\\\underline{\ \ \: + \, 11} \ \ \ \, \underline{+ \, 11}\\x \ \ \ \ \ \ \: = -17\)

\(x = -17\)

So, the integer that makes the equation true is -17.

The figure created with the points (-2, -3), (-2, 5), (1, -3) and (1, 5) is a rectangle.

A rectangle is oblong. It has two pairs of parallel sides and four right angles. A rectangle can also be known as an equiangular quadrilateral. This is because a rectangle is a quadrilateral shape (4-sided shape) that has parallel sides, equal to one another, and all 4 corners have angles that are 90º.
