Answer:
1/8 or 0.125
Step-by-step explanation:
Let x be the length of the sides of the square ABCD.
Therefore, the length of CN and CM is x/2.
The area of the triangle MCN is:

The area of the square ABCD is:

Thus, the probability that a random point lies in the triangle MCN is:

The probability that the point will lie in the triangle MCN is 1/8 or 0.125.
Given:
Cost of two donuts and three cookies = $3.30
Cost of five donuts and two cookies = $4.95
To find:
The cost of each donut.
Solution:
Let x be the cost of each donut and y be the cost of each cookie.
Cost of two donuts and three cookies = $3.30
...(i)
Cost of five donuts and two cookies = $4.95
...(ii)
Multiply equation (i) by 2.
...(iii)
Multiply equation (ii) by 3.
...(iv)
Subtracting (iii) from (iv), we get


Divide both sides by 11.


Therefore, the cost of each donut is $0.75.
Answer:
The correct option is C
Step-by-step explanation:
Lets find the linear equations:
For Hours
Let
Number of hours in bookstore per week = x
Number of hours for babysitting per week = y
Total number of hours ≤ 16
So the first equation us:
x + y ≤ 16
y ≤ 16 - x
For Money
Let
Amount earned per hour from bookstore = $4
Total Amount earned from bookstore = 4x
Amount earned per hour from babysitting = $8
Total Amount earned from babysitting = 8y
Total Amount earned ≥ $56
So the second equation is:
4x + 8y ≥ 56
8y ≥ -4x + 56
y ≥ -(1/2)x + 7
Answer:
sorry for such a late answer but the correct option is the second table
