The value of the 7's in 4777 from left to right is 7= 700 then 7= seventy and 7 = 7.
That is the hundreds place, the tens place, and the ones place,
180/60 = the number of student for 1%
180/60 = 3
so 1% of the school's population is 3 students
so, 3 x 100 = 300 students
and to check:
300 x .60 = 180
so, the total population of the school is 300
Answer:
5.76
Step-by-step explanation:
The net shows an equilateral triangle with side length 24 cm.
The area of an equilateral triangle of side length s is ...
... A = (√3)/4·s²
Using the above side length, the area is
... A = (√3)/4·(24 cm)² = 144√3 cm² ≈ 249.4 cm²
Your best choice is the first one:
... A) 249.6 cm²
1487.93 should be the correct answer I believe.
