Answer:
x=360 30-40 yrs =288
Step-by-step explanation:
multiple 72 by .05 (36) to find 10 percent, then multiple 80 percent by that number(36) then add both numbers together to get total number of members that month
(72x.05)=36x2+(.80x36)=288
288+72=360
The amount, in oz of butterscotch chips needed by proportional reasoning is; 75oz.
<h3>What is the amount of butterscotch chips needed by proportional reasoning?</h3>
It follows from the task content that the the amount of butterscotch chips needed can be determined by means of the proportion premise declared in which case;
- The recipe requires 3 times as many chocolate chips as butterscotch chips.
Hence, when 25oz of chocolate chips is used, the amount of butterscotch needed is 3 times 25 and hence, = 3 × 25 = 75oz.

For question number 1:The plot H = H(t) is the parabola and it reaches its maximum in the moment when exactly at midpoint between the roots t = 0 and t = 23. At that moment t = 23/2 or 11.5 seconds.
For question number 2:To find the maximal height, just simply substitute t = 11.5 into the quadratic equation. The answer would be 22.9.
For question number 3:H(t) = 0, or, which is the same as -16t^2 + 368t = 0.Factor the left side to get -16*t*(t - 23) = 0.t = 0, relates to the very start of the process, when the ash started its way up.The other root is t = 23 seconds, and it is precisely the time moment when the bit of ash will go back to the ground.
