Answer:
The total amount of Jolly Ranchers in the container is 60 Jolly Ranchers
Step-by-step explanation:
We have a ratio of
Red Jolly Ranchers : Green Jolly Ranchers
3:7
Sum of the proportion = 3 + 7 = 10
Hence:
Let the total number of jolly ranchers = x
7/10 of x = 42 Green Jolly Ranchers
Hence:
7/10 × x = 42
7x /10 = 42
Cross Multiply
7x = 420
x = 420/7
x = 60 Jolly Ranchers
The total amount of Jolly Ranchers in the container is 60 Jolly Ranchers
Since the standard card deck has 52 cards, the correct answer is A. 1/52
We are going to calculate D=b²-4ac , if it less than 0 , the equation will not have real solutions
1. D=4²+4*2*12 positive 2 real solutions
2. 2x²-x-12=0
D=1²+4*1*12 positive 2 real solutions
3. 2x²+4x+12=0
D=16-4*2*12=16-96=-80 no real solutions , correct answer C
4. D=16-4*2*0=16 two real solutions
Answer:
18
Step-by-step explanation:
mack has 18cats because she has 2×9 cats as Wayne 2×9 is 18
The total number of vegetables in there are 118, 13 of them being carrots, the possibility is 13/118, or decimal form would be about 11.02%
