In the diagram below, what is the ratio of unshaded parts to shaded parts?

4 shaded triangles and 12 unshaded triangles.
4 unshaded to 9 shaded
9 unshaded to 4 shaded
3 unshaded to 1 shaded
1 unshaded to 3 shaded

Answers

9514 1404 393

Answer:

  (c) 3 unshaded to 1 shaded

Step-by-step explanation:

If your description of the diagram is correct that there are 12 unshaded and 4 shaded triangles, then the desired ratio is ...

  unshaded : shaded = (12 unshaded) : (4 shaded) = 12 : 4 = 3 : 1

__

The ratio is reduced to lowest terms by dividing both numbers by the greatest common factor, 4. The order of parts of the ratio needs to match the requested order: unshaded to shaded. The given numbers are in reverse order, requiring that you actually read and understand the question.

Answer:

the answer is 3 unshaded to 1 shaded

Answer:

slope= 3/4

y=mx+b

Step-by-step explanation:

Answer:

3/4

Step-by-step explanation:

The rate of change is referring to the slope, which can be calculated by rise/run.  There are two points we can use to find the slope: (0,3) an (4,6), but feel free to use any points on the graph that you want to.  Between those two points, the function's y value ("rise") increases by 3, while the function's x-value ("run") increases by 4.  Divide 3 (rise) by 4 (run) in order to calculate the rate of change.

Ms. Romero runs a house cleaning business. To save money, she bought a 1-gallon container of concentrated cleaner. She mixed the cleaner with 10 gallons of water. Then, she filled as many 1-pint spray bottles as she could. How many spray bottles did she fill?

Answers

Answer:

88

Step-by-step explanation:

The number of 1-pint spray bottles she can fill with 11 gallons is 88.

What is unit conversion?

It is the conversion of one unit to another unit with its standard conversion.

Example:

1 km = 1000 m

1 hour = 60 minutes

We have,

The quantity of cleaner and water mixed.

= 1 gallon + 10 gallons

= 11 gallons

Now,

1 gallon = 8 pint

Multiply 11 on both sides.

11 gallon = 88 pints

Thus,

The number of 1-pint spray bottles is 88.
