The unknown side is 9. Because 9 x 5= 45, 45 being the perimeter, that is 5 times the unknown side. And 45 is the sum of 9, 16, and 20.

Two cards are drawn one at a time from a full deck of cards. a) What’s the probability they are an ace or a heart? b) What’s the
nika2105 [10]

Probability of ace drawn is: 4/52

Probability of heart drawn is: 13/52

For question (a)

P(ace or heart)=p(ace) + p(heart)

P(ace or heart)=4/52 + 13/52

P(ace or heart)=17/52

For question (b)

P(ace)' =1 - 4/52 = 48/52

P(heart) =1 - 13/52 = 39/52

P(neither ace nor heart) = 48/52 × 39/52

School meeting was attended only by sophomores, juniors, and seniors. 5/12 of those who attended were juniors, and 1/3 were seni
Veronika [31]
If \frac{9}{12} of students were juniors and seniors that leaves the 36 sophomores to be \frac{3}{12} or \frac{1}{4} of attendees. I got \frac{9}{12} by converting \frac{1}{3} to \frac{4}{12} by multiplying it by 4 and adding it to \frac{5}{12}.

Now if 36 is \frac{3}{12} of the equation that means theirs at least 36 juniors and seniors.

Lets start with seniors. there should be just over 36 of them there. Lets start by multiplying 36 by \frac{3}{12} to figure out how many \frac{1}{12} is.
The equation would look like this 36*(3/12)
start with 3/12. this equals .25 or \frac{1}{4}.
Now multiply 36 by .25. this equals 9.

We have 9 students per \frac{1}{12} of the attendees.

To get the amount of seniors add 9 to 36 \frac{4}{12} because we already stated \frac{3}{12} is 36.
36+9=45

Now to find the juniors add another 9 to create \frac{5}{12}.
45+9=54

In total you have:
36 sophomores
54 juniors
45 seniors

Victor had 15-kilometers start on Chase. How long will it take Chase to catch Victor if Victor travels at 65 kilometers per hour
BigorU [14]

Answer:

  1/2 hour

Step-by-step explanation:

The head start distance is being reduced at the rate of (95-65) = 30 km/h. Chase will catch Victor after ...

  time = distance/speed = (15 km)/(30 km/h) = 1/2 h

It will take Chase 1/2 hour to catch Victor.

An Native American tepee is a conical tent. Find the number of cubic feet of air in a teepee 10 ft. in diameter and 12 ft. high.
marta [7]
For this case what you should know is that by definition the volume of the cone is given by:
 V = ((pi) * (r ^ 2) * (h)) / (3)
 Remembering that:
 r = d / 2
 Substituting the values:
 V = ((pi) * ((d / 2) ^ 2) * (h)) / (3)
 V = ((pi) * (((10) / 2) ^ 2) * (12)) / (3)
 V = 314.16 ft ^ 3
 Answer:
 V = 314.16 ft ^ 3
 The nearest option is:
 300 cu. ft
