The answer is b:
First change the operation to multiplication, and then change the last fraction to it's reciprocal (7/15 / 5/3)
Then, you can simplify 15 and 5 to 3 and 1 (divide each by 3)
Finally u multiply (7*1 / 3*3)

Answer:

Approximately 1.9 seconds (correct to nearest tenth)

Step-by-step explanation:

Looks like the function is d = -16t^2 + 55 ( you left out the t)

The answer is the value of t when d = 0 so we have the equation:-

0 = -16t^2 + 55

16t^2 = 55

t^2 = 55/16

t = sqrt (55/16)

= 1.85 seconds

Lostsunrise [7]

Answer:

$\frac{2}{5}*\frac{3}{5} +\frac{2}{5}*\frac{2}{5}+\frac{3}{5} *\frac{3}{5} = \frac{19}{25}$

Step-by-step explanation:

We must remember that in order to get one even number we need to multiply one even number times one odd number or two even numbers. So, the first term tells the probability of having an even number from A and an even number from B, the next would be even from A and odd from B and the last one tells the likelihood of having odd from A and even from B
