A12= 708588
Formula: a1 * r^n-1
a12= -4 * (-3) ^12-1
a12= -4 * (-177147)
a12= 708588
The grocer prepared total 110 samples.
<em><u>Explanation</u></em>
Suppose, the total number of samples the grocer prepared is
By lunchtime, the grocer has given out 5 fewer than half the total number of samples. So, the number of samples given out by lunchtime
Now, it is given that she gives out 50 samples before lunch. That means...
So, the total number of samples the grocer prepared is 110.
Answer:
The answer for the algebraic expression is >> 7
The answer should be h(x)=x+4
The surface area of a right circular cone is SA =<span>
</span>
The diameter (d) is equal to 20 meters and half of it is equal to the radius which is 10 meters.
The height (h) of the tank is equal to 42 meters.
Substituting the given to the equation:
SA =
= 1670.51 square meters or the closest answer is 1,671 m2
