Sí un solo cristal obstruye el 10% de la luz pasa por él, entonces el porcentaje de luz que pasa a través de n cristales consecutivos está dado aproximadamente por la ecuación p=100e^-0.1n

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
