Step-by-step explanation:
The probability that you will choose a lemon-lime for your friend is the number of lemon-limes divided by the total number of drinks, 4/11.
The probability that you will subsequently choose one for yourself is the same ratio with different numbers (because a lemon-lime has already been selected), 3/10.
The probability of both of these events occurring is the product of their individual probabilities: (4/11)·(3/10) = 6/55
Answer:
24 minutes
Step-by-step explanation:
Distance = speed x time
12 mi = 30 mi/h x time
time = 12/30 = 4/10 hours
since 1 hour has 60 minutes
4/10 hours x 60 = 24 minutes
Answer:
It will take her 24 minutes to get there.

Answer:
50
Step-by-step explanation:
difference of ratio=7-3=4
sum of ratio=3+7=10
if difference 4 total=10
if difference 20 total=10/4×20=50
Answer:
sin(A-B) = 24/25
Step-by-step explanation:
The trig identity for the differnce of angles tells you ...
sin(A -B) = sin(A)cos(B) -sin(B)cos(A)
We are given that sin(A) = 4/5 in quadrant II, so cos(A) = -√(1-(4/5)^2) = -3/5.
And we are given that cos(B) = 3/5 in quadrant I, so sin(B) = 4/5.
Then ...
sin(A-B) = (4/5)(3/5) -(4/5)(-3/5) = 12/25 + 12/25 = 24/25
The desired sine is 24/25.
Answer:
Anurak has 15 pennies, 6 nickels and 3 dimes.
Step-by-step explanation:
We must have these informations in mind:
1) A penny is a 1-cent coin.
2) A dime is a 10-cent coin.
3) A nickel is a 5-cent coin.
Let be , , the quantities of pennies, nickels and dimes, respectively. From statement we get that to value in Anurak's pocket is represented by this mathematical expression:
(Eq. 1)
In addition, we get the following identities:
i)He has three more nickels than dimes
(Eq. 2)
ii)And five times as many pennies as dimes
(Eq. 3)
The system of linear equations is now reduced: (Eqs. 2, 3) in (Eq. 1)
The remaining variables are and .
Anurak has 15 pennies, 6 nickels and 3 dimes.
Answer:
Anurak has 15 pennies, 6 nickels and 3 dimes.
Step-by-step explanation:
Answer:
2. 180-115 = 65
3. angle = 90-37 = 53
4. angle = 90 - 15 = 75
5. angle = 90-43 = 47
6. 109+71 = 180 = S
7. 19+71 = 90 = C
8. 89+1 = 90 = C
9. 34+56 = 90 = C
10. 75+75 = 150 = N
11. 16+74 = 90 = C
12. 90+90 = 180 = S
13. 65+115 = 180 = S
Hope this helps
