What is 65% of 47? Please help me fast.

liubo4ka [24]

'of' in math implies that the values are being multiplied together, so multiply 47 and 65%;
47 * 65% = 47 * .65 = 30.55

(8.08×10^-10)÷(4.0×10^-3) in scientific notation?

saw5 [17]

Answer:

$\large\boxed{2.02\times10^{-7}}$

Step-by-step explanation:

The scientific notation:

$a\cdot10^k\\\\1\leq a$

We have:

$(8.08\times10^{-10})\div(4.0\times10^{-3})\\\\=\dfrac{8.08\times10^{-10}}{4.0\times10^{-3}}\\\\=\dfrac{8.08}{4}\times\dfrac{10^{-10}}{10^{-3}}\qquad\text{use}\ \dfrac{a^n}{a^m}=a^{n-m}\\\\=2.02\times10^{-10-(-3)}\\\\=2.02\times10^{-7}$

. Find the measure of an angle which is 46° less than its complement

OLEGan [10]

Answer:

Complementt angle = 44°

Step-by-step explanation:

Given:

One angle = 46°

Find:

Complementt angle

Computation:

In complement angle

∠A + ∠B = 90°

46° + ∠B = 90°

∠B = 90° - 46°

∠B = 44°

Complementt angle = 44°
