The length of an arc of a circle is 7.34 units, and the measure of the corresponding central angle is 81 degrees. What is the ap

GuDViN [60]

Answer:

A. 5.19 units

Step-by-step explanation:

$\textsf{Arc length}=2 \pi r\left(\dfrac{\theta}{360^{\circ}}\right) \quad \textsf{(where r is the radius and}\:\theta\:{\textsf{is the angle)}$

Given:

$\theta$ = 81°
Arc length = 7.34 units

Substituting given values into the equation and solving for r:

$\implies 7.34=2 \pi r\left(\dfrac{81^{\circ}}{360^{\circ}}\right)$

$\implies 7.34=r\left(\dfrac{18 \pi}{40}\right)$

$\implies 7.34 \cdot 40=18 \pi r$

$\implies 293.6=18 \pi r$

$\implies r=\dfrac{293.6}{18 \pi}$

$\implies r=5.19 \sf \: units \:(2\:dp)$

When do you get an answer to a system of linear equations that has one solution, no solution and infinitely many solutions?

meriva

Answer:

Step-by-step explanation:

One solution: when two lines intersect in exactly one point.

Infinitely many solutions: When one of two lines can be shown algebraically to be exactly the same as the other. The two lines coincide.

No solution: The two lines have the same slope but different y -intercepts. They can't and don't intersect.

A cell phone service provider offers two plans. Plan A includes a fee of $25 per month and charges $0.25 for every call. Plan B

Drupady [299]

First of all calm down and brake down the problem plan a is $25 a month while the other one is $40 you need to subtract to get $15 than divide $15 by $0.25 which you will get 60 but this is not the right answer because its asking you how many phone calls is the cost of plan b less than the cost of plan a so the answer is 59 calls.

The scale of a map is 1:250000. On the map a large forest has an area of 6cm². Calculate the actual area of the forest. Give you

Bad White [126]

The distance on map exists 32 cm and actual area exists 37.5 km².

<h3>How to estimate the actual area of the forest in square kilometers?</h3>

Given: Scale of the map exists at 1:250000.

(a) Distance between two cities = 80 km

= 80000 m

= 8000000 cm

Distance on map = 8000000 $*$ 1/ 250000
