Answer:
x = 51
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
x² = 45² + 24² = 2025 + 576 = 2601 ( take the square root of both sides )
x = = 51
Answer: 15 students
Step-by-step explanation:
From the question, we are informed that there are 150 students in 6th grade, and that 10% earned straight As last quarter.
The number of students that earned straight As will be:
= 10% × 150
= 10/100 × 150
= 0.1 × 150
= 15 students
8x - 6 - 8 = 4 + 2x
8x - 14 = 4 + 2x
8x = 4 + 2x + 14
8x = 2x + 18
8x - 2x = 18
6x = 18
x = 18/6
x = 3
*Answer is x = 3 because 18/6 is 3 since 3 * 6 = 18.
Answer:
23
Step-by-step explanation:
<h3>Arithmetic sequence:</h3>
In arithmetic sequence, the difference between any consecutive terms is constant and the progression goes either in ascending order or in descending order.
a = first term = 2
a₂ = 5
difference = d = second term - first term
= 5 - 2
d = 3
Formula for finding nth term in arithmetic sequence:
t₈ = 2 + (8 -1) * 3
= 2 + 7 *3
= 2 + 21
t₈ = 23
