Answer:
1/5
Step-by-step explanation:
Answer:
$30
Step-by-step explanation:
If $25 is 100%,
$2.5 is 10%
$0.25 is 1%
$3.75 is 15%
$0.75 is 3%
Then add $25, $3.75 and 0.75 which is also equivalent to 100%+15%+3%=29.5 and if you rounded it up to the nearest cent it is 30
The answer is choice D) 4
(x/4) times 4 = x
You can think of it as
(1/4) times 4 = 1
Answer:
see explanation
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
Summing the 3 angles and equating to 180 gives
2x + 3 + 4x + 2 + 2x - 1 = 180
8x + 4 = 180 ( subtract 4 from both sides )
8x = 176 ( divide both sides by 8 )
x = 22
∠A = 2x + 3 = (2 × 22) + 3 = 44 + 3 = 47°
∠B = 4x + 2 = (4 × 22) + 2 = 88 + 2 = 90°
∠C = 2x - 1 = (2 × 22) - 1 = 44 - 1 = 43°
They're trying to trick you with √2. Remember in the 30/60/90 triangle the sides are in ratio 1:√3:2, with the "1" opposite the 30 degrees.
Here we have
1:√3:2 = 6√2:x:hypotenuse
or
x/(6√2) = √3/ 1
x = 6√2×√3 = 6√6
Answer: AC=6√6
