At a zoo in a butterfly enclosure, 5 drops of nectar is sufficient for 2 butterflies. How many butterflies could be fed with 59 drops of nectar?
Answers
Answer:
111 can i get brailyist for replying so fast.
Answer:
23
Step-by-step explanation:
[tex] \frac{2}{5} \times \frac{x}{59} [/tex]
the number of drops of nectar goes on the bottom, and the number of butterflies goes on the top
then you cross multiply to get 5x= 118
solve for × and you get 23.6
for this situation, 0.6 of a butterfly doesn't make sense, so we need to round down.
we round down because it's okay if there's extra nectar, but there can't be less than enough.
you can be 23 butterflies with 59 drops of nectar

TRIGONOMETRY REVIEW RATIOS FINDING SIDES & ANGLES PLEASE DUE TOMORROW !!!!

Using the Trigonometry ratios, the missing sides and angles are:
1. sin R = 5/13
2. sin T = 12/13
3. cos R = 12/13
4. cos T = 5/13
5. tan R = 5/12
6. tan T = 12/5
7. x = 16.5
8. x = 58.9
9. x = 9.2
10. x = 35.9
11. x = 40.7°
12. x = 77.8°
What are the Trigonometry Ratios?The Trigonometry ratios that can be used to solve any right triangle are given as: SOH CAH TOA.
SOH is: sin ∅ = opp/hyp
CAH is: cos ∅ = adj/hyp
TOA is: tan ∅ = opp/adj.
1. sin R = opp/hyp = 15/39
sin R = 5/13
2. sin T = 36/39
sin T = 12/13
3. cos R = adj/hyp = 36/39
cos R = 12/13
4. cos T = 15/39
cos T = 5/13
5. tan R = opp/adj = 15/36
tan R = 5/12
6. tan T = 36/15
tan T = 12/5
7. Apply CAH:
cos 38 = x/21
x = (cos 38)(21)
x = 16.5
8. Apply TOA:
tan 23 = 25/x
x = 25/tan 23
x = 58.9
9. Apply TOA:
tan 57 = x/6
x = (tan 57)(6)
x = 9.2
10. Apply SOH:
sin 32 = 19/x
x = 19/sin 32
x = 35.9
11. Apply SOH:
sin x = 15/23
x = sin^-1(15/23)
x = 40.7°
12. Apply TOA:
tan x = 37/8
x = tan^-1(37/8)
x = 77.8°

A random number generator is set to generate integer random numbers between 1 and 10 inclusive following a uniform distribution. What is the probability of the random number generator generating a 7
Answers
Answer:
1/10 or 10%.
Step-by-step explanation:
If the generator includes the numbers 1 and 10 then there are a total number of 10 possible number outcomes that the number generator can generate. Out of all of these outcomes, only one of those would be generating a 7. Therefore, the probability of the generator generating a 7 would be 1/10 or 10%. This is assuming that it only generates 1 number.

Mrs. Rogers sold 49 out of 78 crafts at the fair. What percent of her crafts did she sell? Please show work!
Answers
Answer:
62 32/39%
Step-by-step explanation:
[tex]\frac{49}{78}*\frac{100}{1}=\frac{4900}{78}=\frac{2450}{39}=62\frac{32}{39}%[/tex]%
The percentage of Mrs. Rogers crafts sold is 62.82%.
Given that, Mrs. Rogers sold 49 out of 78 crafts at the fair.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Percent of crafts sold =Number of crafts sold/Total number of crafts ×100
= 49/78 ×100
= 0.6282×100
= 62.82%
Therefor, the percentage of Mrs. Rogers crafts sold is 62.82%.
