Round off 0.043 to one significant figure

aniked [119]

Hey there :)

0.043
The first 0 before the decimal point is not significant since it is used for cosmetic purpose
The 0 after the decimal is not significant as the 0 is used to locate the decimal point
The 4 is the first nonzero integer and it counts as a significant figure

Therefore, 0.04 will be your answer rounded to 1 s.f

An angle measures 8.2° more than the measure of its complementary angle. What is the

nikitadnepr [17]

9514 1404 393

Answer:

49.1°, 40.9°

Step-by-step explanation:

Let x represent the smaller angle. Then the larger is x+8.2 and the total of the two angles is ...

x + (x +8.2) = 90

2x +8.2 = 90 . . . . . collect terms

x + 4.1 = 45 . . . . . . .divide by 2

x = 40.9

x +8.2 = 49.1

The two angles are 49.1° and 40.9°.

Hunter invested $750 in an account paying an interest rate of 6\tfrac{5}{8}6 8 5 % compounded continuously. London invested $7

kompoz [17]

Answer: $ 55

Step-by-step explanation:

When interest is compounded continuously, the final amount will be

$A=Pe^{rt}$

When interest is compounded daily, the final amount will be

$A=P(1+\dfrac{r}{365})^{365t}$

, where P= Principal , r = rate of interest , t = time

For Hunter , P= $750, r = $6\dfrac{5}{8}\%=\dfrac{53}{8}\%=\dfrac{53}{800}=0.06625$

t = 18 years

$A=750e^{0.06625(18)}=\$2471.48$

For London , P= $750, r = $6\dfrac{1}{2}\%=\dfrac{13}{2}\%=\neq \dfrac{13}{200}=0.065$

t = 18 years

$A=750(1+\dfrac{0.065}{365})^{18(365)}=\$2416.24$

Difference = $ 2471.48 - $ 2416.24 =$ 55.24≈$ 55

Hence, Hunter would have $ 55 more than London in his account .
