Answer:
B= 15 adults tickets
C= 35 student tickets
Step-by-step explanation:
x+y=50
solve for y
y=50-x
5x+3y=180
5x+3(50-x)=180
5x+150-3x=180
2x=30
x=15
y=50-15
y=35
Answer:
25.
Step-by-step explanation:
I am assuming you only mean the small triangles, not the composite ones.
The second triangle set has 3 triangles on bottom row and 1 on the top - total 4.
The 3rd triangle set has 5 triangles on the bottom , 3 on the next up and 1 on the top - total 9
Following the pattern 4th set will have the number of triaNGLES
7 + 5 + 3 + 1 = 16.
So the 5th will have 9 + 7 + 5 + 3 +1 = 25 triangles.
Answer: 0.4302
Step-by-step explanation:
Given : Mean : 
Standard deviation : 
Sample size : 
Also, these distances are normally distributed.
Then , the formula to calculate the z-score is given by :-

For x=32.5

For x=40.5

The p-value = 

Hence, the required probability :-0.4302

Answer:
333.67 miles
Step-by-step explanation:
She drives her car 91 mi on 3 gal of gas
That’s 91 mi = 3 gal
How many miles can she drive on 11 gal of gas .
Let the mile she can drive by 11 gal of gas be A
At the same rate ,
91 mi = 3 gall
A mi = 11 gal
Cross multiply
A x 3 = 91 x 11
A x 3 = 1001
Divide both sides by 3
A x 3/3 = 1001/3
A = 333.67 miles
At the same rate she’ll drive 333.67 miles on 11 gal of gas
