Answer:
adult tickets 6.9
children tickets 3.9
Step-by-step explanation:
3x + y = 24.60 L1
5x + 4y = 50.10 L2
5L1 - 3L2
15x + 5y = 123
-15x - 12y = -150.3
-7y = -27,3
y = -27,3/-7
y = 3.9
3x + y = 24.60
3x + 3.9 = 24.60
3x = 24.60 - 3.9
3x = 20.7
x = 20.7 / 3
x = 6.9
Answer: 4/8
Step-by-step explanation:
Equation: 1/8+x=5/18
-1/8 -1/8
x=4/8
Double Check: 4/8+1/8=5/8
Answer:
b. 75 days
Step-by-step explanation:
Answer:
16.66%
Step-by-step explanation:
The probability would be the multiplication of the different events.
First event, take out a white rose and plant it, the probability of that is 2/4 = 1/2
Second event, take out a red rose and plant it, the probability is 2/3.
Third event, take out another red rose and plant it, the probability is 1/2.
Now, the probability of everything is:
(1/2) * (2/3) * (1/2) = 0.166
that is to say, the probability of what the statement asks us to happen is 16.66%
Answer:
The answer to the question is
The probability that the 2 rosebushes in the middle of the row will be the red rosebushes = 1/6
Step-by-step explanation:
To solve the question we note that the required permutation is WRRW
Therefore the total number of ways to plant the four rose bushes given that two white rose bushes are in the middle is given by
4!/(2!2!) = 6 Therefore the probability that the 2 rosebushes in the middle of the row will be the red rosebushes = 1/6
Answer:
lhs = (5+2√3)/(7+4√3)
= [(5+2√3)(7-4√3)]/[(7-4√3)(7+4√3)]
=[35-20√3+14√3-24]/[7²-(4√3)²]
=[11-6√3]/[49-48]
=11-6√3
therefore
11-6√3 = a+b√3
compare both sides
a= 11, b= -6
Step-by-step explanation:
Hope this answer helps you :)
Have a great day

Answer:
a = 11, b = 6
Step-by-step explanation:
Given
Rationalise the denominator by multiplying numerator/ denominator by the conjugate of the denominator.
The conjugate of 7 + 4 is 7 - 4
= ← expand numerator/ denominator using FOIL
=
=
= 11 - 6
with a = 11 and b = 6
