How would you round off .002353 to two significant figure please?

1 answer:

4 0

The answer is 0.024.

Let's round decimal by decimal until we get two significant figures.
When the successor number is smaller than 5 then the predecessor number remains the same.
When the successor number is greater than 5 then the predecessor number rounds to the first greater number.
If the successor number is 5 then the even predecessor number remains the same and the odd predecessor number rounds to the first greater number.
0.002353 ≈ 0.00235
0.00235 ≈ 0.0024

Now, we have two significant figures: 2 and 4

Answer:

B=45

Step-by-step explanation:

let the supplamentary angle of <A is <d

180-A=d

180-135=d

45=d

90+d+B=180

90+45+B=180

135+B=180

B=180-135

B=45

A baby weights 18 pounds at her four month appointment. Six months later she weights 24 pounds. By what percentage did the baby’

Anna11 [10]

Answer: 25%

Step-by-step explanation:

Given : Previous baby's weight = 18 pounds

New baby's weight = 24 pounds.

Increase in weight = New weight -Previews weight

=24 pounds - 18 pounds =6 pounds

Percentage increase in baby's weight = $=\dfrac{\text{Increase in baby's weight}}{\text{previous weight}}\times100$

$\\\\=\dfrac{6}{24}\times100=25\%$

Hence, the percentage increase in baby's weight = 25%

A 50-gallon rain barrel is filled to capacity. It drains at a rate of 10 gallons per minute. Write an equation to show how much

makvit [3.9K]

Answer:

The quantity of water drain after x min is 50 $(0.9)^{x}$

Step-by-step explanation:

Given as :

Total capacity of rain barrel = 50 gallon

The rate of drain = 10 gallon per minutes

Let The quantity of water drain after x min = y

Now, according to question

The quantity of water drain after x min = Initial quantity of water × $(1-\dfrac{\textrm rate}{100})^{\textrm time}$

I.e The quantity of water drain after x min = 50 gallon × $(1-\dfrac{\textrm 10}{100})^{\textrm x}$

or, The quantity of water drain after x min = 50 gallon × $(0.9)^{x}$

Hence the quantity of water drain after x min is 50 $(0.9)^{x}$ Answer

Find the value of x that makes ABCD a parallelogram.

olganol [36]

The angle 5x will be 50⁰. Then the correct option is D.

<h3>What is a parallelogram?</h3>

It is a polygon with four sides. The total interior angle is 360 degrees. A parallelogram's opposite sides are parallel and equal.

The diagram is given below.

We know the sum of internal angles is 360 degrees.

Then we have

5x + 130 + 5x + 130 = 360

10x = 100

x = 10

Then the angle 5x will be

5x = 5(10)

5x = 50⁰

Then the correct option is D.

A boutique prices merchandise by adding 80%. It later decreases by 25% the price of items that do not sell quickly. Does the ord

k0ka [10]

The order you apply the adjustments does make a difference because the percents that are applied will be applied to different amount.

For example, 80% of 100 = $80. The price would be $180.

Decreasing this by 25% 25% of 180 = $45; 180-45 = $135.

25% of 100 is not the same as 25% of 180.
