Answer:
The camera is sold for $ 59.26.
Step-by-step explanation:
From the statement we understand that the new price of the camera (
) is calculated by:
(1)
Where:
- Price after increase, measured in US dollars.
- Increase rate, expressed in percentage.
If we know that 
and 
, then the new price of the camera is:
The camera is sold for $ 59.26.
A^2+B^2=C^2 so 16+25=81 then no ,but it can be an obtuse triangle because the equation a^2+b^2
Answer:
w ≥ 6
l ≥ 11
Step-by-step explanation:
The perimeter of a rectangle is equal to P = 2l+2w where l=length and w=width. Here the length is 5 feet longer than the width or 5+w. This means the width is w. Substitute P = 34, l=5+w and w into the perimeter equation. Then solve for w.
34 ≤ 2*(5+w) + 2w
34 ≤ 10+2w+2w
34 ≤ 10+4w
24 ≤ 4w
6 ≤ w
This means the width must be at least 6 so the solution is w ≥ 6.
To find the length substitute 6 into l ≤ 5+w.
l ≤ 5 + 6
l ≤ 11
The length is l ≥ 11.
Use the Pythagorean theorem!
This principle applies to any right triangles.
This states the relationship between the sides that
(7)² + (24)² = x²
All you have to do is simplify at this point.
49 + 576 = x²
625 = x²
√ √
x = 25
You should try to memorize this right triangle. It can be very helpful in fast questionnaires, such as the SAT.
4 x 10^-7 (7 x 10^-9) (1 x 10^4) (2 x 10^4)
