Answer:
Area of floor = 21.6m2
area of tile = 576cm2=0.0576m2
now,
number of tiles = 21.6/0.0576
= 375
Answer:
Kindly check explanation
Step-by-step explanation:
To compare the number of apples to oranges
Number of apples = 12
Number of oranges = 10
Number of apples in terms of oranges :
12 /10 = 1.2
Number of apples = 1.2(number of oranges)
If number of apples = x
Number of oranges = y
x = 1.2y
There are 1.2 times the number of apples than number of oranges.
Answer:
The probability of 1 or less children from that group to learn how to swim before 6 years of age is 0.072
Step-by-step explanation:
In this case we need to compute the probability of none of these 12 children learns to swim before 6 years of age. This is given by:
p(0) = (1 - 0.312)^(12) = 0.688^(12) = 0.01124
We now need to calculate the probability that one child learns to swim before 6 years of age.
p(1) = 12*0.312*(1 - 0.312)^(11) = 3.744*(0.688)^(11)
p(1) = 3.744*0.01634
p(1) = 0.0612
The probability of 1 or less children from that group to learn how to swim before 6 years of age is:
p = p(0) + p(1) = 0.01124 + 0.0612 = 0.07244
Use distributive
3f - 15 - 9 = -3
Combine like terms
3f - 24 = -3
Add 24
3f = 21
Divide by 3
f = 7
![v = \frac{1}{3} \pi {r}^{2} h \\ r = 8 \: cm \\ h = 15 \: cm](https://tex.z-dn.net/?f=v%20%3D%20%20%5Cfrac%7B1%7D%7B3%7D%20%5Cpi%20%7Br%7D%5E%7B2%7D%20h%20%5C%5C%20r%20%3D%208%20%5C%3A%20cm%20%5C%5C%20h%20%3D%2015%20%5C%3A%20cm)
From the diagram, we can see that the radius of the cone is 8cm and the height of the cone is 15cm. We then just plug these numbers into the formula and simplify:
![v = \frac{1}{3} \pi {r}^{2} h \\ v = \frac{1}{3} \pi {(8)}^{2} (15) \\ v = 320\pi](https://tex.z-dn.net/?f=v%20%3D%20%20%5Cfrac%7B1%7D%7B3%7D%20%5Cpi%20%7Br%7D%5E%7B2%7D%20h%20%5C%5C%20v%20%3D%20%20%5Cfrac%7B1%7D%7B3%7D%20%5Cpi%20%7B%288%29%7D%5E%7B2%7D%20%2815%29%20%5C%5C%20v%20%3D%20320%5Cpi)
The volume of the cone is approximately 1005.3096 cm^3. With 3 sig figs, this is 1010 cm^3.
