First we write the kinematics equations:
a
v = a * t + vo
r = a * (t ^ 2/2) + vo * t + ro
For Wanda we have: a = 0
v = 5
r = 5 * t
For Dave we have: v = 10
r = 10 * (t-120)
To solve the system of equations, we graph both functions and see where
they intersect.
We have to intersect in the ordered pair:
(t, r) = (240, 1200)
answer If they continue walking at these rates, Dave catch up to Wanda in 240s (1200 ft)
The answer is 53. You just need to find the magnitude
Answer:
The total cost of the cylindrical tank is $226.28
Step-by-step explanation:
Dimensions of the tank are: radius = 3 ft , height = 2 ft
Cost per cubic foot = $4
Now, total volume of the cylindrical tank = 
Here, take π = 22/7
So, Volume = 
So, the <u>volume of the tank = 56.57 cubic feet. </u>
Now, cost per cubic foot = $4
Hence, the total cost of the tank = Total Volume of the tank x cost per foot
= 56.57 x 4 = $226.28
So, the total cost of the cylindrical tank is $226.28
<span>We can quickly calculate a ten percent tip by moving the decimal place one to the left. So a 10% tip on $85.00 would be $8.50. We can then take half of that tip to calculate the remaining 5%. $8.50 / 2 = $4.25. The sum of these two results is equal to a 15% tip. $8.50 + $4.25 = $12.75. The correct answer is D.</span>
Answer:
AB =24
Step-by-step explanation:
So, since all the sides are equal, you can just take two of the sides and set em equal to each other to find x and then, solve for AB
4x+8 =6x
8= 6x-4x
8=2x
8/2 =x
x= 4
Now, find AB, which is 4x+8
4(4) + 8
16+8 = 24
