Answer:
915
Step-by-step explanation:
V=l*w*h V=1/2*b*h*l
V of the rectangular block: 15*5*8 = 600
V of the triangular prism--it's easiest to solve half of it, then just multiply that answer by 2: 1/2*5*7*9 = 157.5
When you double it, it cancels out the 1/2
157.5*2=315
315+600=915
Answer:480 pounds
Step-by-step explanation: 30 pounds a day equals 210 a week and 30 days equals 2 weeks and 2 days. 210 pounds of fish every week for 2 weeks equals 420 pounds plus 60 from the other 2 days equals 480
Answer:
The flow rate is 138.95 mL per hour.
Step-by-step explanation:
We are given the following in the question:
Volume of solution = 2.64 L
1 L = 1000 mL
Volume of solution in mL =
Time period = 19 hour
Unit rate of flow =
Thus, the flow rate is 138.95 mL per hour.
Xy is the number
A) x + y = 7
B) 10y + x = 10x + y + 9
collecting terms of equation B
B) -9x + 9y = 9
multiplying A) by 9
A) 9x + 9y = 63 then adding it to equation B)
B) -9x + 9y = 9
18y = 72
y = 4
x = 3
The number is 34
