Answer:
d, 1/6
Step-by-step explanation:
so i did a diagram of some sorts to do this and got around six possible outcomes.
h is heads, t is tails.
h-h-h
t-t-t
h-t-h
t-h-t
t-t-h
h-h-t
feel free to correct me if any of this is wrong.
Answer:
105:175
Step-by-step explanation:
3+5 = 8
3/8 of 280 is 105.
5/8 of 280 is 175.
the ratio is 105:175
next we have to simplify it:
divide both sides by 5:
21:35 divide both sides by 7=
3:5
A = π r²
A = (3.14) (1.2)²
A = 4.52 m²
Answer:
The fith number is 80.
Step-by-step explanation:
A geometric sequence is a group of numbers that are related to it's neighbours by a product of a constant ratio. In order to calculate a certain number in such sequences we can use the formula:
an = a1*q^(n-1)
Where "n" is the position of the number we wish to know and q is the ratio. To use the formula we need to know the first number and we were given the third, so we first need to find that. We have:
a3 = a1*q^(3 - 1)
20 = a1*2^(2)
a1*4 = 20
a1 = 20/4 = 5
So the 5th number is:
a5 = a1*q^(5-1)
a5 = 5*2^(4)
a5 = 5*16 = 80
The fith number is 80.
