Which of the following decimal numbers equals 4 thousands, 9 hundreds, 2 tens, and 6 ones?

1 answer:

7 0

4,926 is the answer since of the expanded form written, 4,000 + 900 + 20 + 6, but there is no decimal since nothing says tenths or hundredths or thousandths.

Hope this helped!

Find the value of b that will make the equation sin 62°= cos B true when 0°

KiRa [710]

Hello from MrBillDoesMath!

Answer:

b = 28 degrees

Discussion:

In general,

sin (90 - @) = cos(@)

Set 90 [email protected] = 62 => @ = 28 so

sin (90-28) = sin(62) = cos(28) => b = 28

Thank you,

Proof:

$8\div\frac{1}{6}=\frac{8}{1}\div \frac{1}{6}=\frac{8}{1}\times\frac{6}{1}=\frac{8\times6}{1}=\frac{48}{1}=48 \\$

Assume ABC Company deposits $90,000 with First National Bank in an account earning interest at 6% per annum, compounded semi-ann

maw [93]

Answer:

Step-by-step explanation:

I'm goig to assume that the formula we need here is the following:

$A(t)=P(1+\frac{r}{n})^{(n)(t)$

where A(t) is the amount in the account after the compounding is done, n is the number of times per year the compounding occurs, r is the rate in decimal form, and t is the time in years. Filling in accordingly,

$A(t)=90000(1+\frac{.06}{2})^{(2)(5)}$ and simplifying a bit,

$A(t)=90000(1.03)^{10}$ and simplifying a bit more,

A(t) = 90000(1.343916379) so

the amount in the account after 5 years is

A(t) = 120,952.47
