What number could be added to 0.40 mL for the level pf precision to be 0.01mL?

Mathematics
1 answer:
Mila [183]3 years ago
4 0

Answer:

-0.39mL

Step-by-step explanation:

Let x be the number.

The expression would be: 0.40 + x = 0.01

Apply algebra to the equation to solve for x. You can subtract 0.40 from each side to simplify the expression. Here's what it should look like after applying algebra: x = -0.39

Therefore the answer is -0.39mL

For 12 days, Keisha keeps track of how much water she drinks per day. her results are shown below
mezya [45]

The total amount of water that Kiesha drinks in 12 days is 20 quarts

The average amount of water she drinks per day is 1 2/3 quarts

The number of days that Keshia drinks at least the average amount of water is 6 days

If she drinks 1 quart of day 13, the average reduces.

<h3>What is the average ?</h3>

The total amount of water drank in the 12 days can be determined by adding the quarts for each day together. When they are added together, the number is 20 quarts.

Average = total amount drank / number of days 1 2/3 quarts

New average = 20 + 1 / 13 = 21 / 13 = 1 7/13 quarts

The average reduces because the quart drank on the 13th day is less than the amount of water drank on the other days.

Line m includes the points (-3, 3) and (-4,-6). Line n has the same slope as line m and
Sveta_85 [38]

For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cut-off point with the y axis

The slope of a line is given by:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}

We have that the line m passes through the following points:

(x_ {1}, y_ {1}): (-3,3)\\(x_ {2}, y_ {2}): (-4, -6)

So, the slope of the line m is:

m = \frac {-6-3} {- 4 - (- 3)} = \frac {-9} {- 4 + 3} = \frac {-9} {- 1} = 9

Line n has the same slope so the equation is of the form:

y = 9x + b

We have as data that the y-intercept is -\frac{2} {3}. Thus, we have that the equation of line n is:

y = 9x- \frac {2} {3}

ANswer:

y = 9x-\frac {2} {3}

Elenna [48]

Answer:

100% increase

Step-by-step explanation:

well first let's find out how much a 100% increase would be. 6,540 + 6,540(when trying to find a 100% change add the number to itself) = 13,080. that gets the answer, so there is no need to continue.
