Answer: plan A lasts for 0.5 hour. Plan B lasts for 0.75 hour.
Step-by-step explanation:
Let x represent the duration of plan A.
Let y represent the duration of plan B.
On Friday there were 3 clients who did plan A and 2 who did Plan B.
Joe trained his Friday clients for a total of 3. It means that
3x + 2y = 3- - - - - - - - - -1
On Saturday there were 5 clients who did plan A and 6 who did plan B. Joe trained his Saturday clients for a total of 7 hours. It means that
5x + 6y = 7- - - - - - - - - 2
Multiplying equation 1 by 5 and equation 2 by 3, it becomes
15x + 10y = 15
15x + 18y = 21
Subtracting, it becomes
- 8y = - 6
y = - 6/-8
y = 0.75
Substituting y = 0.75 into equation 1, it becomes
3x + 2 × 0.75 = 3
3x + 1.5 = 3
3x = 3 - 1.5 = 1.5
x = 1.5/3
x = 0.5
Answer:
the answer to your problem is 15
Step-by-step explanation:
Answer:
5. They are not the same
6. They are the same
Step-by-step explanation:
5. The triangles internal angles are not the same, for triangle efg the 2 angles add to 133, leaving a third angle of 47, which is not the same as the angle in the other triangle of 57
6. If the two angles in triangle wxq are add, they add to 147, thereforw the last angle is 33, which is the same as the other triangle. The sides are also paralell so the sides are the same
Answer:
Step-by-step explanation:
So we have a rectangle and a triangle.
The height you can find for the triangle is 12ft
And for the rectangle it is 6ft
Formula for area on triangle is 1/2(b*h)
Or for the given picture
A = .5(15 * 12)
= 90ft^2 ( The area of the triangle)
Next for the rectangle
C = length * width
= (3 * 6)
= 18ft^2 (area of rectangle)
Boom that is it no Pi needed
Step-by-step explanation:
1/2 on the first round, then 1 on the second. When you have 2 juice boxes on the first round, there is a 50/50 (reduce to 1/2) chance that you will get one or the other. But after one is chosen, there is one left, because there is no replacement, and it is guarantied that the one will be picked. 100/100 or 1.
