If you would like to know how many pounds of flour remain after Anne bakes 3 batches of rolls and Anne has a 10 3/4 pounds bag of flour and each time she bakes one batch of rolls, she uses 2 1/6 pounds of flour, you can calculate this using the following steps:
for 3 batches of rolls, she needs:
3 * 2 1/6 = 3 * 13/6 = 13/2 = 6 1/2 pounds of flour
now, you have to subtract 10 3/4 and 6 1/2:
10 3/4 - 6 1/2 = 43/4 - 13/2 = 43/4 - 26/4 = 17/4 = 4 1/4 pounds of flour
Result: 4 1/4 pounds of flour remain after Anne bakes 3 batches of rolls.
Answer:
C
Step-by-step explanation:
Answer: there are 200 girls in the school.
Step-by-step explanation:
In a school, there is a ratio of 4 boys to 5 girls. The total ratio would be the sum of the proportion of boys and the proportion of girls. Therefore,
Total ratio = 4 + 5 = 9
If there are a total of 450 students, it means that the number of girls in the school would be
Proportion of girls/ total ratio × total number of students. Therefore,
The number of girls is
5/9 × 450 = 200
The geometric sequence is starting with 2 and multiplying by 3 every time. We can get the rule of this sequence by...
If 2 is a_0, 6 is a_1, 18 is a_2, etc.
a_n=2*3^n
For the 14th term, which is a_13, the value is 2*3^13.
Using a calculator because I'm too lazy to calculate 3^13 sorry, we can get.
