Is it possible to construct a sector such that the length of the radius is equal to the length of the arc created by its central angle?

Explain why or why not, and include the radius lengths and central angle measures that you tried.

Answers

Answer:

No

A 30 degree central angle would be a 30 degree arc.

The sin of 30 degrees is 0.5 so the arc would be just greater than 15, much less than 30.

A fox, a coyote, and a wolf weigh a total of 120 pounds. The ratio of the weight of the fox to the weight of the coyote is 3:8. The weight of the coyote is 32 pounds. What is the weight of the wolf?
PLEASE HELP I WILL REWARD BRAINLIEST

Answers

Answer:

so you divide 32 by 8 which gets you to 4. then you multiply 4 by 3 to get 12. The weight of the form is 12 pounds. you then subtract 44 (the weight of the fox and coyote combined) from 120. which leaves you at 76. si the weight of the wolf is 76 pounds (the ratio is 3:8:19 because 76 divided by 4 is 19)

Step-by-step explanation:

Answer:

52 square units

Step-by-step explanation:

Drop a perpendicular from the top left vertex to the bottom base creating a right triangle. You have a 30-60-90 right triangle with the ratio of the lengths of the sides being 1 : sqrt(3) : 2

Then, the height of the trapezoid is the triangle's opposite leg to the 60-deg angle.

The triangle's adjacent leg to the 60-deg angle is half the hypotenuse, or 3 units.

The height is sqrt(3) times the adjacent leg.

The base of the trapezoid has length 3 + 7 + 3 = 13

A = (b1 + b2)h/2

A = (13 + 7)(3sqrt(3))/2

A = 51.96

Answer: 52 square units

Solve for the following triangle

Answers

Answer:

50

Step-by-step explanation:

as 40 + 90 + ? = 180 (Angle sum property)

so ? = 180 -130 = 50

The area of a right triangle is 180 degrees,
We know the 2 angles are 90 and 40, To get the third angle you add 90 + 40 to get 130.
Now minus the hole area of the right triangle from the two added angles, (180 - 130) to find out the missing angle is 50 degrees.

find the numerical value of the log expression

Answers

Answer:

9

Step-by-step explanation:

I'm going to solve this question by expanding the logarithm (note that you can also solve this equation by solving for a, b, and c)

We know the following

[tex]log(ab)=log(a)+log(b)[/tex]

Which means we can split the numerator into

[tex]log(b^{1/2})+log(c^{3/2})[/tex]

We also know that

[tex]log(a^{x})=x*log(a)[/tex]

Which means that we can rewrite the following as

[tex]\frac{log(b)}{2}+\frac{3log(c)}{2}[/tex]

We can evaulate this and get

-1+12= 11

for the numerator

Now we need to take care of the denominator

we know the following

[tex]log(\frac{x}{y})=log(x)-log(y)[/tex]

which means that we have

11-2log(a)

solve and get

11-2

$154.00
$163.00
$187.00

Answers

Answer:

A. $154.00

Step-by-Step Explanation:

Okay so, the first step is to get 12% and move the decimal to the left twice like this:

.12

Then, multiply 175 by .12 like this:

175 * .12 = 21

Lastly, subtract 21 from 175 like this:

175 - 21 = $154

The answer is a - $154.00

A convex hexagon has exterior angles of 54°, 38°, 41°, 64°, and 66°. What is the measure of an exterior angle at the sixth vertex?

Answers

Answer:

Step-by-step explanation:

Sum of external angles of a polygon is always 360°.

Sum of five external angles = 54° + 38° + 41° + 64° +66° = 263°

sixth external angle = 360° - 263° = 97°
