Answer:
On Saturday night it had sold 35 numbers of cups.
Step-by-step explanation:
On the Saturday night the ratio of the number of cones to the number of cups sold is 6 : 5 in Freshly frozen yogurt however on Sunday night the ratio of the number of cones to the number of cups is 4 : 1.
Now, if the Freshly frozen yogurt sold 42 cones on Saturday night then in the ratio of 6 : 5, it sold cups times the number of cones.
Therefore, on Saturday night it had sold numbers of cups. (Answer)
After 200 years, 9.84 grams of Cesium would remain.
Let N represent the amount of substance after t years
The half-life of a cesium is 30 years., hence, this can be represented by exponential function:
where a is the initial value and b is the multiplier.
There were initially 1000g of the substance
a) The exponential model for this situation is:
b) After 200 years (t = 200), the amount of Cesium remaining is:
Hence after 200 years, 9.84 grams of Cesium would remain
