Answer:
93%
Step-by-step explanation:
.53 equals 53% because decimals are basically percents in disguise. 1 would equal 100%, 0.23 would equal 23%, 0.03 would equal 3% and so on.
Your answer is option 3. Dashed lines because the inequality on either line is NOT an "or equal to" statement.
Answer:
x=1/f
Step-by-step explanation:
<span>In 3x - y = -1
-y = -3x - 1 {subtracted 3x from both sides to get into slope-intercept form}
y = 3x + 1 {divided both sides by -1}
the slope is 3 {the number in front of the x}
The slopes are the same in both equations, therefore
the lines are parallel.</span>
Answer:
<u>The correct answer is that the area of the regular octagon is 309 cm²</u>
Step-by-step explanation:
There are several formulas for calculating the area of a regular octagon. We will use this one for solving this question because it does not require additional information .
Area = (2 * s²)/tan 22,5°
s = 8 cm
Replacing with the real values, we have:
Area = (2 * 8²)/tan 22,5°
Area = 2 * 64/0.4142
Area = 128/0.4142
<u>Area = 309 cm² (Rounding to the nearest tenth)</u>
