Answer:
21 / 400
Step-by-step explanation:
Given 8 cherry, 5 grape, and 7 orange gummy vitamins out of the multivitamin container.
The probability that Julio will select an orange multivitamin is
7 ÷ 8 + 5 + 7 = 7/20
Also, given 11 berry, 3 lemon, and 6 pineapple gummy vitamins out of the calcium container
The probability that Julio will select a lemon calcium is
3 ÷ 11 + 3 + 6 = 3/20
Therefore, since the event of selecting are independent of each other
probability that Julio will select an orange multivitamin and a lemon calcium vitamin is
7/20 × 3/20
= 21 / 400
Answer:
6 hours
Step-by-step explanation:
Let both of them plan for t hours to plant 111 trees n t hours
Melissa can plants 10 trees in 1 hour
in t hours she can plant 10 t trees
Jane plants 17 tree in 2 hours
in one hour Jane can plant 17/2 trees
in t hours she can plant (17/2)t trees.
Total trees planted by both of them in t hours in terms of t will be
10t + (17/2)t
= (10t*2 + 17t)/2
= (20t + 17t)/2
= 37t/2
but it is given that they planted 111 trees together
so 37t/2 should be equal to 111
37t/2 = 111
=> 37t = 111*2 = 222
=> t = 222/37 = 6.
Thus, it takes 6 hours for both of them to plant 111 trees together.
Answer:
The of depression between the cliff and the boat is 48.74 degrees.
Step-by-step explanation:
We have,
Height of the cliff is 200 foot
Distance of boat from the cliff is 175 feet
It is required to find the angle of depression between the cliff and the boat.
Here, 200 foot is perpendicular distance and 175 is base.
Using trigonometry :

So, the of depression between the cliff and the boat is 48.74 degrees.
Answer:
100 kobo
Step-by-step explanation:
100%-55%=45% 45%=67 and 1/2 what about 100%=? You cross multiply= <u>100%× 67</u><u>1/2</u>
45% = = <u>100%× 135 ×1 </u> = 2 45% = = 50× 2 = 100 100 ÷2=50 135÷45=2 % cancelled % So the final answer = 100
