Step-by-step explanation:
I think your question should be what is the probability that the second card is a spade given that the first one was a club
3/2 = 1.5
Let the value of the 1945 coin = x.
Then, the value of the 1950 coin = 1.5x
Together, they are worth $40. This gives us the equation:
x + 1.5x = 40
2.5x = 40
x = 40/2.5
x = 16
1.5x = 1.5 * 16 = 24
Answer: The 1945 coin is worth $16. The 1950 coin is worth $24.
Answer:
a = - 13
Step-by-step explanation:
Giv en
- 7 +
= - 11 ( add 7 to both sides )
= - 4
Multiply both sides by a
52 = - 4a ( divide both sides by - 4 )
a = - 13
Answer:
440cm³
.45
1.49538 ft
43.6
Step-by-step explanation:
1.
Start by finding the area of the base
.5*(a+b)*h
.5*(8+14)*4= 44
Then just multiply this by distance between the ends
44*10=440
2.)
To get from 2.7 to 9 we muiltply by 9/2.7= 3.33333333
which means that
3.333333333x=1.5
x=.45
3.)
Height:shadow
6.5:1.8
5.4:x
To get from 6.5 to 5.4 we multiply it by (5.4/6.5) or .8307
which means to get from 1.8 to x we muiltply 1.8*.8307= 1.49538
4.)
Same kind of deal as the last one
to get from 13 to 27 we mulitply by (27/13) or 2.076923 which means to get from 21 to x we multuply 21*2.076923=43.6
Answer:
i think it is 100.53125 !! hope i helped :)
