When you estimate, you round each number, the add.
We round them to
700+620, which is 1320
So our non estimated answer is 1323
But our estimated answer is 1320
so,it is the answer that you are looking for.please mark me as brainliest.
5/9, is what it should be
Step-by-step explanation:
Number of students who wore a hat
= 4/7 * Number of students who bought a ticket
= 4/7 * 350 students
= 200 students.
Number of students not wearing a hat
= Number of students who bought a ticket - Number of students who wore a hat
= 350 students - 200 students
= 150 students.
Answer:
a= 20
b= 169.7
c= 29.71
Step-by-step explanation:
The formula of a triangle is (h*b)/2
a= (5*8)/2
b= to find the height, you can use the pythagorean theorem 18^2 - 6^2 = square root of 288. Which is 12root 2 or 16.97. (16.97*20)/2
c= using the pythagorean theorem- 11^2 = 7^2 - c^2 = square root 73, or 6root 2, or 8.49. (8.49* 7)/2
