Mr. Demers is making a drink by adding flavor drops to his water. If he puts 3 drops in a 12 ounce glass of water, how many ounces does he use PER DROP?

Answers

Answer:

Step-by-step explanation: if he puts 3 drops in a 12 ounce glass of water he should be using 4 ounces per drop 12 ounces divided by 3 drops gives you 4 ounces per drop

Answer: 4 ounces per drop

=======================================================

Explanation:

"Per drop" means "per 1 drop" or "for each 1 drop".

We start off with the ratio of

3 drops: 12 ounces

Divide both parts of that ratio by 3 so that "3 drops" turns into "1 drop"

Doing so gets us the new ratio of

1 drop: 4 ounces

So he uses 4 ounces per drop.

Martha estimated there were 91 marbles in a jar for a contest. The actual number of marbles in the jar was 113. What was the percent error of Martha's estimation?
A. 24.18%
B. 80.53%
C. 22%
D. 19.47%

Answers

Answer:

D. 19.47

Step-by-step explanation:

91/113 = 80.53

100.00-80.53 = 19.47

Answer:

19.47% to the nearest hundredth.

Step-by-step explanation:

Value of the error = 113 - 91 = 22.

Percent error = (22/113) * 100

= 19.47.

Which is the most accurate way to estimate 52% of 63

Answers

You can put 63 in the calculator and multiply is by .52 which will give you 32.76

How would you solve this?

Answers

Answer:

For the equation, you should subtract 2x on both sides to get -y = -2x - 4.  Flip the y's negative sign to get a proper function which is y = 2x + 4.  The y-intercept is at (0, 4) and each unit will move two units up along the x-axis.

A wheel makes 35 revolutions per min. How many revolutions does it make per second?
The wheel makes revolutions per second.
(Type an integer or a simplified fraction.)

Answers

Answer:

7/12 revolutions per second

The wheel makes revolutions per second is 7/12.

What is the unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, a wheel makes 35 revolutions per min.

Here,

35/1 minute × 1 minute/60 seconds

= 35/60

= 7/12 revolution per second

Therefore, the wheel makes revolutions per second is 7/12.
