The\: missing\: length\: is\: 5

leonid [27]3 years ago

Answer:

? = 5

Step-by-step explanation:

Since the figures are similar then the ratios of corresponding sides are equal, that is

\frac{21}{7} = \frac{15}{x} ( cross- multiply )

21x = 105 ( divide both sides by 21 )

x = 5

That is ? = 5

Tom plants 3 seeds.
Rasek [7]

Answer:

A. 64/125

B. 124/125.

Step-by-step explanation:

A).  As the events ( germinate or not germinate) are independent we multiply the probabilities.

Prob(All seeds germinate) = 4/5*4/5*4/5 =  64/125.

B). Probability of at least one germinating =  1 - probability that none germinate

Probability of  1 seed not germinating = 1 -45 = 1/5.

So Prob(at least one germinating)

= 1 - (1/5 * 1/5 * 1/5)

= 1 - 1/125

= 124/125.

Plz answer all SHOW WORK
Andrews [41]
Okay, so if it leaks out a pint every hour, and a gallon is 8 pints, it will take 8 hours to leak out 1 gallon. Since there are 24 hours in a day, it would leak out 3 gallons every day. Now, assuming the month we are talking about is 31 days, then we multiply 31 with 3, giving us 93 gallons in a month. 
Do you need help with the third too?
