All you have to do is multiply 10 x 407.7 = 40.77 which is the answer.
But if you want to do it an a easier way you just move the decimal point one time to the left to get your answer so you wont need to use a calculator to figure that out.
Hope that helped!!

The answer is 4077. All we have to do to find the answer is do inverse operations. Since the opposite of division is multiplication we would have to multiply 407.7*10 which equals 4077. To check our answer we simply divide 4077/10 =407.7 and we find that it matches! Hope this helps!
Answer:
V=4/3πr^3;S=4πr^10;dV/dt=dV/dr×dr/dt=4πr^10×dr/dt;dS/dt=dS/dr×dr/dt=8πr×dr/dt=2/r×dV/dt;当r=10cm时,dS/dt=50cm^2/s
Step-by-step explanation:
The expression w/4 + 12.5 - 7z comprises three terms - w/4, 12.5, and -7z, which are separate values in the expression.
The expression you provided, w/4+12.5-7z, has three terms. In algebra, terms are the separate values in a word that are added or subtracted. Here, w/4, 12.5, and -7z are all different terms. Each term may be a number, a variable, or a combination of numbers and variables multiplied together, like -7z.
