A washing machine is filling up with water at a constant rate. The rate is 3/4 of a gallon in 1/5 of a minute. Don calculated the unit rate to be 3/20 of a gallon per minute. what did he do wrong?​

Answers

Answer 1

Answer: you have to see how many gallons fill the container per minute, so take 3/4 and divide it by 1/5, which gives 15/4. So he multiplied the two numbers instead of dividing.

Step-by-step explanation:

Answer 2

Answer:

[tex]\frac{15}{4}[/tex] gallon per minute

Step-by-step explanation:

Given parameters:

Quantity of gallon = [tex]\frac{3}{4}[/tex] gallon

Time taken  = [tex]\frac{1}{5}[/tex] min

Unknown:

The solution is [tex]\frac{3}{20}[/tex] gallon per minute, what did he do wrong = ?

Solution:

To find the rate:

   Rate  = [tex]\frac{Quantity of gallon}{time }[/tex]

 Input the parameters and solve

  Rate  = [tex]\frac{\frac{3}{4} }{\frac{1}{5} }[/tex]   = [tex]\frac{3}{4}[/tex]  ÷ [tex]\frac{1}{5}[/tex]

                       Invert the [tex]\frac{1}{5}[/tex]  to give 5

                  =  [tex]\frac{3}{4}[/tex] x 5

                  = [tex]\frac{15}{4}[/tex] gallon per minute

The student failed to invert the [tex]\frac{1}{5}[/tex] before multiplying with  [tex]\frac{3}{4}[/tex]

Answer:

D.  Multiply/divide both sides by the same variable expression.No

Step-by-step explanation:

1) Comparing the two equations, we see that the multiplier 'x' is missing from both sides in equation B. That is, it has been divided out:

  (5x)/x = (3x)/x   ⇒   5 = 3

Both sides have been divided by x.

__

2) The equations are equivalent if and only if x ≠ 0. Unfortunately, in equation A, the only solution is x = 0. For equations like the one in A, it is better to subtract one side from both:

  5x -3x = 3x -3x   ⇒   2x = 0

Now, dividing by 2, it is clear that the solution is x = 0.

Equations A and B are not equivalent, because the condition on the division property of equality was violated (you cannot divide by 0).

Tonya's class planted sunflowers and the students are tracking the growth of their individual plants. The table
shows the height of
Tonya's plant t days after she planted her sunflower seed

Based on the data in the table, what function h(t) represents the height, h, in inches, at time t?

Answers

Answer:

Here's what i did

Step-by-step explanation:

The answer is h = 0.4t

A linear function is a function in the form of:

y = mx + b;

where y, x are variables, m is the slope of the line and b is the y intercept.

We can use the data in the table to find the relationship between the time (t) and height (h)

Let us use the format (height, time). Hence from the table, we have the points:

(4, 10), (8, 20), (12, 30) and (16,40). Using any two points, in this case (4, 10) and (16,40), we can apply the formula:

[tex]h-h_1=\frac{h_2-h_1}{t_2-t_1} (t-t_1)\\\\h-4=\frac{16-4}{40-10} (t-10)\\\\h-4=0.4(t-10)\\\\h-4=0.4t-4\\\\h = 0.4t[/tex]

Was wondering what it meant byexpress as a power of 2?​

Answers

Answer:

Expressing a number in a power of 2 means that you have to figure out how many times you should multiply 2 by itself so the product will be that number.

The number is expressed as 2^n

For example:

Express 16 as a power of 2:

To get 16, you have to multiply 2 by 4 times.

2 × 2 × 2 × 2 = 16

16 = 2^4

Then the answer is 2^4

Answers

Answer:

yes

Step-by-step explanation:

By the converse of Pythagoras' identity.

If the longest side squared is equal to the sum of the squares of the other 2 sides, then the triangle is right.

longest side = 50.5

50.5² = 2550.25

10² + 49.5² = 100 + 2450.25 = 2550.25

The perimeter of a rectangle is 130 cm. If the breadth of the rectangle is 30

cm, find its length. Also find the area of the rectangle.​

Answers

Answer:

The length is 35cm and the area is 1050cm^2

Step-by-step explanation:

The perimeter of a rectangle is all of the side lengths added together. "Breadth" is your width. So 2 x 30 + 2 x some length is your perimeter. Mathematically this can be represented as:

[tex]60+ 2x=130[/tex]

[tex]2x=70[/tex]

[tex]x=35[/tex]

For the area multiply 30 by 35

[tex]30*35=1050[/tex]

And your answer for the area is in cm^2
