<u>Answer:</u> The given statement is true.
<u>Step-by-step explanation:</u>
Significant figures are defined as the figures that are present in a number. It expresses the magnitude of a quantity to a specific degree of accuracy.
There are some rules to detect the significant figures in a number:
- All digits ranging from 1 to 9 are always considered significant.
- Every non-zero number is always considered significant. For example, 274, 2.74, and 27.4 all have three significant figures.
- All zero’s that are present between the integers is always considered significant. For example, 5007, 5.007, and 50.07 all have four significant figures.
- All zero’s preceding the first integer is never considered significant. For example, 0.0089 has two significant figures.
- All zeros that are present after the decimal point are always significant. For example, 4.800, 48.00, and 480.0 all have four significant figures.
<u>Rule applied when numbers are added or subtracted:</u>
The number having less number of significant figures after the decimal point will determine the number of significant figures in the final answer.
Hence, the given statement is true.
Answer:< B = 15°
Step-by-step explanation:
If m\angle A=(x+16)^{\circ}∠A=(x+16) and m\angle B=(3x-14)^{\circ}∠B=(3x−14), then find the measure of \angle A∠A.
$34 is a proper 20% tip on a $171.81 dinner. Move the decimal point twice to the left, then multiply that twice.
There is 23.6 gallons in a 100 lb propane tank
Answer:
The correct answer is 54.76 years.
Step-by-step explanation:
The national health care expenditure (H) , in billion of dollars is modeled by
H = 29.57 × 
.
To measure the time before which national health expenditure reach 6000 billion dollars.
Thus putting the value of H = 6000 in the above modeled equation we get,
⇒ 6000 = 29.57 ×
⇒ 
=
⇒ 202.908 =
Taking logarithm with the base of e (㏑) both sides we get,
⇒ ㏑ 202.908 = ㏑
⇒ ㏑ 202.908 = 0.0970 × t
⇒ 0.0970 × t = 5.312
⇒ t = 
⇒ t = 54.76.
Thus the total time required before which national health expenditure reach 6000 billion dollars is 54.76 years.
