radians is equal to 90°.
Step-by-step explanation:
Step 1:
If an angle is represented in radians, it will be of the form radians.
If an angle is represented in degrees, it will be of the form x°.
To convert radians to degrees, we multiply the radian measure by .
For the conversion of radians to degrees,
the radians in degrees = (given value in radians)().
Step 2:
To convert ,
So radians is equal to 120°.
Answer:
The fencing would cost a total of $961.33 rounded to the nearest hundredth
Step-by-step explanation:
Circumference: 2πr (r = 18 or 1/2 diameter)
2 × 3.14 × 18 = 113.097336
113.097336 × $8.50 = $961.327356, which rounds up to $961.33
Answer:
x=-7
Step-by-step explanation:
xe^-x+7e^-x=0
factor out the e^-x
e^-x(x+7)=0
e^-x=0, x+7=0
-x=ln(0), x=0-7=-7,
since ln(0) is undefined,
the only solution is -7.
This is not a math problem, i think. you should post it on biology.
the answer is e.
i'd like to explain it to you, but sorry, i can't, because i'm not a native english speaker. i can't explain such a difficult problem in english.
Answer:
Step-by-step explanation:
Let's first understand what percentage of the population actually exists after the decrease.
<h3>100% - 35% = 65% of the population.</h3>
We'll now convert 65% into a decimal. We can convert percentages into decimals by dividing the percentage by 100.
<h3>0.65 / 100 of the population.</h3>
We'll now make an equation.
<h2>0.65x = 29,900</h2><h2>x = 46,000.</h2><h3>Keep in mind that x, in the equation, is to represent the previous population. When you multiply it by 0.65, you're representing 65% of x which is also equal to 29,900. When you multiply the equation by (100/65) on each side, you find out the previous population is 46,000.</h3><h2>If you have issues or difficulties, feel free to contact me.</h2>
