8 0

Answer:

1/4, 25%, or 0.25

Step-by-step explanation:

Therefore, as each suit contains 13 cards, and the deck is split up into 4 suits, that leaves us with a 13/52 chance to pick a spade.

That fraction is equivalent to 1/4, so that leaves us with a probability of picking a spade at:

1/4, 25%, or 0.25

Answer:

C. 0.23°

Step-by-step explanation:

We are given

$r=\frac{1}{32}v^{2}sin(2\theta)$

Re-arranging this equation (multiply by 32 on both sides and divide by $v^{2}$ on both sides gives us:

$\frac{32r}{v^{2}}=sin(2\theta)$ or

$sin(2\theta)=\frac{32r}{v^{2}}$

Substituting for, r and v we get

$sin(2\theta)=\frac{(32)5000}{4500^{2}}=0.00792\\\\\theta=sin^{-1}(0.0079)=0.4527\\\\\theta=\frac{{0.4527}}{2}=0.2263\approx0.23$

What number is 344% of 107

olga55 [171]

Answer:

368.08

So I turn the numbers into fractions so 344% would be 344/100 because percentages are out of 100. Since it is 344% OF 107, you'd put 107 on the bottom of the fraction and the answer will go on top. I multiply the IS with the OF (IS is the top number and OF is the bottom) so you'd multiply 107x344 to get 36808. Since 344 is a percent (out of 100) you have to do divide the answer by 100 to get 368.08

I hope that helps!
