A. Yesterday, Kelly went to the Sea Animal Park on a class trip. The Sea Animal Park had a total of 3,840 visitors for the first 3 weeks of the month. There were 1,368 visitors the first week and 1,277 visitors the second week. What was the number of visitors for the third week? Show your work. B. During the first 3 weeks, 18 buses full of stừdents visited the Sea Animal Park. Each bus had 54 students. What is the total number of students that visited the Sea Animal Park during the 3 weeks? Explain how you found your answer.

C. Yesterday, on Kelly's class trip, 4 groups of 52 students visited the Sea Animal Park. The students attended a special dolphin show in which they were able to pet the dolphins. The students were placed in groups, with 7 students in each group. Kelly used division to find the total number of groups that were needed so that each student was able to pet the dolphins. She said that a total of 29 groups were needed. Did Kelly correctly solve the division problem? Why or why not?

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.

step-by-step explanation:

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
