The lengths of the boards are 6 cm and 8 cm.
The boards make a right angle.
Therefore the string connecting the boards is the hypotenuse of a right triangle (shown n the figure).
By the Pythagorean theorem,
c² = 6² + 8² = 100
c = 10 cm
Answer: c = 10 cm
Answer:
19 keyboards
Step-by-step explanation:
Let d = thumb drives; and k = computer keyboards
Total number of sales of thumb drives and keyboards is 50
50 = d + k
Rearranged:
d = 50 - k
Total revenue from the sale of $24 thumb drives and $49 keyboards is $1675
1675 = 24d + 49k
Sub in d = 50 - k
1675 = 24(50 - k) + 49k
1675 = 1200 - 24k + 49k
475 = 25k
k = 475/25
k = 19
(To check, d = 50 - 19 = 31)
Answer:
15, 17, 19
Step-by-step explanation:
let the first odd number be n then the next 2 are n + 2 and n + 4 , then
n + n + 2 + n + 4 = 51
3n + 6 = 51 ( subtract 6 from both sides )
3n = 45 ( divide both sides by 3 )
n = 15
Then
n + 2 = 17 and n + 4 = 19
The 3 consecutive odd numbers are 15, 17, 19
