The equation for volume of a sphere is:
Volume = 4/3 * PI * r^3
r is the radius = 1 inch
Volume is given as 4 cubic inches per second increase.
Given: dv/dt = 4 cubic inches per second.
Need to find dr/dt
Formula for volume of a sphere is: V = 4/3 * π * r^3
so now we have:
4 in^3 = 4 * π *1^2
Divide both sides by 4 * π *1^2
4 in^3 / 4π = 1/π inch per second.
The answer is 1/π inch per second ( exact answer)
or as a decimal: 0.3183 ( round as needed).
Answer:
$(x - 1425)/3
Step-by-step explanation:
Let total monthly budget be x
Amount spent on mortgage = $1425
Remaining balance after spending on mortgage = x - $1425
Amount spent on recreational activities = one-third of the balance
Expressing amount spent on recreational activities as an equation will give;
Amount spent on recreational activities = 1/3 of x - $1425
= 1/3 × ( x - $1425)
= ( x - $1425)/3
Hence the required equation is;
R = $(x - 1425)/3
R means recreational activities
Answer:
1) 35+5w=110
2) the starting heart rate is 73 beats per minute
3)B
4) 6mins
Step-by-step explanation:
1) since she deposits 5 dollars each week we can multiply 5 and w to find out how much money hes depositing after all the weeks are done. We need to add that with 35 to get the TOTAL money in the bank account.
2) 73 is the y intercept. The y intercept is the number when "x" is 0. So when hes just starting out/not excersizing his heart beats 73 beats per min.
3) we know that 10% of her tips is given back to her hence x(number of tips) is multiplied by 0.1, and added to 50 to find the total amount of money she receives
4) 6 mins for 1 order
