Answer: n=37
Step-by-step explanation:
0.05n+0.10x2n=9.25
0.25n=9.25
n=9.25/0.25
n=37
Answer:
A: 6 triangles with height 10.4 inches each and base 12 inche
B: 62.4 square inches
C: 374.4 square inches
Step-by-step explanation:
Part A: You can form a triangle by connecting E to the top of the segment and connecting the top of the segment to D. Recreating this with each section will create 6 triangles with height 10.4 inches each and base 12 inches.
Part B: The area of a triangle is A = 1/2b*h. Substitute h = 10.4 and b = 12.
A = 1/2*10.4*12 = 62.4
Part C: There are 6 triangles each with area 62.4. So the area of the whole figure will be 6*62.4 = 374.4.
180cm. The square is 6 x 6 = 36 and the triangles = 12 x 6 = 72 and then divide it by 2 = 36 multiply that by 5 and you get 180cm

Correct choice is A
Answer:
4,000 L/h
Step-by-step explanation:
First we'll find the amount of the change.
18,000 - 6,000 = 12,000 L
The time of the volume change was 3 hours: 0230 - 0530
Since we're looking for liters per hour, we will divide the liters (12,000) by the hours (3)
12,000/3 = 4,000 L/h
