Answer:
B. 8
Step-by-step explanation:
Find the percentage of students that are gifted and talented:
(quantity/total) x 100
(60/750) x 100
= 8
So, 8% out of 100% are gifted and talented
This means the sector angle on the pie chart will be B, 8
Hypotenuse = 5√6
Let the length of each leg be x, since it is Isosceles .
x² + x² = (5√6)²
2x² = (5 * 5 * √6 * √6)
2x² = 150
x² = 150/2
x² = 75
x = √75
x = √(25 * 3)
x = √25 * √3
x = 5√3
Answer:
25.9
Step-by-step explanation:
37/10=3.7
3.7*7= 25.9
Answer:
a₂ = - 28.5
Step-by-step explanation:
the nth term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here a₁ = - 45 and given a₃ = - 12 , then
a₁ + 2d = - 12 , that is
- 45 + 2d = - 12 ( add 45 to both sides )
2d = 33 ( divide both sides by 2 )
d = 16.5
Then
a₂ = a₁ + d = - 45 + 16.5 = - 28.5
