Answer 1

There's a very simple rule for geometries like this. The measure of the arc is double the measure of the angle. It helps to remember this.

Your angle is 65°.
The measure of the arc is 2×65° = 130°.

Answer 2

You need to use the central angle.
If you know the radius or how CD works (does it go through the center), then the answer will be less vague. The central angle = 2 * 65 = 130
the length of BC is

130/360 * 2*pi*r
13/18 * pi r is the general answer.

If your front lawn is 15.0 feet wide and 20.0 feet long, and each square foot of lawn accumulates 1450 new snow flakes every minute, how much snow (in kilograms) accumulates on your lawn per hour? Assume an average snow flake has a mass of 1.70 mg.
.. ......

it's my first college chm and I forgot how to do such word problems, would you help me please, thank you

Answers

First determine how many square feet there are in the front lawn.
(15.0 ft) x (20.0 ft) = 300. ft^2
Now find how many snow flakes land in the entire lawn.
(300. ft^2) x (1450 snow flakes/min/ft^2) = 435,000 snow flakes/min
Now find the total mass of snow landing on the lawn per hour.
(435,000 snow flakes/min) x (1.70 mg/snow flake) x (1 kg/1,000,000 mg) x (60 min/1hour) = 44.4 kg of snow per hour.

Answers

65%= 0.65. The probability that all 11 selected graduates found a job in their chosen career would be (0.65)^11, because the probabilities are independent (one person getting a job in their field does not influence another person getting a job in their field). This comes out to 0.009 to the nearest thousandth.

The probability that all the 11 randomly selected graduates will find jobs in their chosen field within a year of graduating is [tex]0.009[/tex] (round to the nearest thousandth).

According to the question, at a certain college shows that 65% of the school's graduates find a job in their chosen field within a year after graduation.

At random 11 candidates are selected from the college so, the probability that all the 11 randomly selected graduates will find jobs in their chosen field within a year of graduating is-

The price of a gallon of unleaded gas has dropped to $2.81 today. yesterday's price was $2.88 . find the percentage decrease. round your answer to the nearest tenth of a percent.

Answers

The percentage decrease is approximately -2.4%.

To find the percentage decrease in price, we can use the formula:

Percentage decrease = ((New price - Old price) / Old price) * 100

Using the given information, we substitute the values into the formula:

Percentage decrease = ((2.81 - 2.88) / 2.88) * 100

Simplifying the expression, we get:

Percentage decrease = (-0.07 / 2.88) * 100

Converting to a decimal and multiplying by 100, we find:

Percentage decrease = -0.0243 * 100 = -2.43%

Rounding to the nearest tenth of a percent, the percentage decrease is approximately -2.4%.

What is the solution of 3+ (x-2)/(x-3) <=4

X<3
X<=3
X>3
X>=3

Answers

I believe that it's x<3

Answer:

A. X < 3.

Step-by-step explanation:

We have the equation, [tex]3 + \frac{x-2}{x-3} \leq 4[/tex]

Adding -4 on both sides, we get,

[tex]\frac{x-2}{x-3} -1 \leq 0[/tex]

i.e. [tex]\frac{x-2-x+3}{x-3} \leq 0[/tex]

i.e. [tex]\frac{1}{x-3} \leq 0[/tex]

So, we have the inequality [tex]\frac{1}{x-3} \leq 0[/tex].

Its critical points are given by x-3 = 0 which implies x = 3.

Now, we will find the region among the two [tex]( - \infty , 3 )[/tex] and [tex]( 3 , \infty )[/tex] that satisfies the inequality [tex]\frac{x-2}{x-3} -1 \leq 0[/tex]

Substitute x = 2 in the above inequality, we get -1 < 0, which is true. Again, substitute x=4 gives 1 < 0, which is false.

As x=4 lie in the region [tex]( 3 , \infty )[/tex] , it cannot be the solution of the given inequality.

So, the solution of the given inequality is the region [tex]( - \infty , 3 )[/tex] .i.e. x < 3.

Hence. option A is correct.

There are web sites and videos that stand ready to show you how to bisect an angle.

The basic idea is that you draw an arc through both rays so that the points of intersection are the same distance from the vertex. Then, you construct a perpendicular bisector of the segment between those intersection points. That will bisect the angle.

For (3), you bisect each of the angles made by the original bisector. (1/2 of 1/2 = 1/4)

A population of 55 foxes in a wildlife preserve doubles in size every 14 years. The function y equals 55 times 2 Superscript x , where x is the number of 14-year periods, models the population growth. How many foxes will there be after 28 years?

Answers

Since x is the number of 14-year periods, the first thing we do is divide 28 years by 14. 28/14=2. Now we use that in our function, [tex]y=55*2^x[/tex].

[tex]y=55*2^2=55*4=220[/tex]
There will be 220 foxes after 28 years.

Final answer:

To find the fox population after 28 years, we use the function y = 55 × 2^x, with x = 2 because 28 years is two 14-year periods. After calculating 2^2 and multiplying by 55, we find that there will be 220 foxes.

Explanation:

To calculate the number of foxes in a wildlife preserve after 28 years, given that the population doubles every 14 years, we start with the function y = 55 × 2^x, where x represents the number of 14-year periods.

Since 28 years is equivalent to 2 periods of 14 years, we will substitute x with 2:

Write down the equation substituting x with 2: y = 55 × 2^2.Calculate the exponent: 2^2 = 4.Multiply the base population by 4: 55 × 4 = 220.

Therefore, after 28 years, there will be 220 foxes in the wildlife preserve.

The total cost of repairing a car is the sum of the amount paid for parts and the amount paid for labor. You paid $132 for parts and $65 for each hour of labor. The total cost to repair the car was $229.50. How many hours did it take to repair the car?

Which equation best models this problem? Let x = number of hours worked

229.5 – 65 = 132x

132x + 65 = 229.5

132 + 65x = 229.5

132 + 65 = 229.50x

Answers

Lets work out the problem from the beginning. Let [tex]x[/tex] be the number of hours worked. We know that you paid $65 for each hour, and remember that the numbers of hours worked is [tex]x[/tex], so you paid for those hours [tex]65x[/tex]. We also know that you paid $132 for parts, a total cost of $229.5, so:
parts + worked hours = total cost
[tex]132+65x=229.5[/tex]
And now that we have our equation from the model, lets solve for [tex]x[/tex] to find how many hours took to the repair the car:
[tex]65x=229.5-132[/tex]
[tex]65x=97.5[/tex]
[tex]x= \frac{97.5}{65} [/tex]
[tex]x=1.5[/tex]

We can conclude that it took 1 and a half hour to repair the car.

step 1

Find the value of x

[tex]m<D+m<B=180\°[/tex]

substitute the values and solve for x

[tex](x+20)\°+(3x)\°=180\°[/tex]

step 3

Find the measure of angle C

[tex]m<C+m<A=180\°[/tex]
