Answer:
Constants
We call them constants because their value never change. Since there are no variables in the term that can change its value.
Answer:
dV/dt = 3×10^2 × 0.5 = 150 in^3/sec
the volume of the cube is increasing at 150in^3/sec
Step-by-step explanation:
Volume V = length l^3
V = x^3
Differentiating both sides;
dV/dt = 3x^2 dv/dt
Given;
x = 10 in
dx/dt = 0.5 in/sec
dV/dt = 3×10^2 × 0.5 = 150 in^3/sec
the volume of the cube is increasing at 150in^3/sec
Answer:
106
Step-by-step explanation:
You divide to find the quotient, the actual answer is 105.7, but I rounded it up for simplicity's sake.
Answer:
Ca(OH)2 + 2 HBr = CaBr2 + 2 H2O
Step-by-step explanation:
Is it H2O2 on the right side and HBr2 on the left side?
Then there is no solution.
I think the formula must look like
Ca(OH)2 + HBr = CaBr2 + H2O
You have 2 Br on the right side then it must be 2 HBr on the left side.
Ca(OH)2 + 2 HBr = CaBr2 + H2O
You have 4 Hs and 2 Os on the left side then it must be 2 H2O on the right side.
Ca(OH)2 + 2 HBr = CaBr2 + 2 H2O
Now everything looks fine.
Answer:
256 pretzels and a total of 15 snack bags.
Step-by-step explanation:
14 * 2 = 28
+
15* 2= 30
+
4 * 16 = 64
+
2 * 18 = 36
+
1 * 19 = 19
+
3 * 20 = 60
+
1 * 21 = 21
28 + 30 + 64 + 36 + 19 + 60 + 20 = 256
256 pretzels
To find the number of bags, count the dots.
There are a total of 15 dots
There are a total of 15 snack bags.
I hope I helped!
