The elevation gained after travelling 1.5 miles = 3960 ft.
Step-by-step explanation:
Given data,
Angle of elevation = 30°
Distance traveled= 1.5 miles
1 mile = 5280 ft.
Therefore 1.5 miles = 5280 x 1.5
= 7920 ft.
The height can be calculated by,
sin 30° = height / 7920
1/2 = height / 7920
Height = 7920/2
= 3960 ft.
The elevation gained after travelling 1.5 miles will be 3960 ft.
$5800 at 9%
$1200 at 11%
0.09(x) = interest earned at 9%
0.11(7000-x) = interest earned at 11%
0.09(x) + 0.11($7000-x) = $654
0.09x + $770 - 0.11x = $654
$770 - $654 = 0.11x - 0.09x
$116 = 0.02x
$116/0.02 = x
$5800 = x
$5800 * 0.09 = $522
($7000-$5800) * 0.11 = $132
Step-by-step explanation:
You can also write it as 45+28.
In English, a double negative is when two negative words are used in the same sentence.
A double negative in Math is when you have a scenario like this. For example, 1-(-1) is also equal to 1+1.
So 45+28 is 73.
