The length of arc JL is $(25)/(18) \pi$ So option c is correct.

Solution:

Given, from the diagram, radius of the given circle is 2 units.

And, the angle between the radius JK and KL is 125 degrees.

We have to find the length of the minor arc formed by JL

The length of arc is given as:

$\text { Length of arc }=2 \pi r\left((\theta)/(360)\right)$

where $\theta$ is angle between radii formed by points with centre

Now the length of arc JL is:

$=2 \pi * 2 * (125)/(360)=4 \pi * (125)/(360)=\pi * (125)/(90)=(25)/(18) \pi$

Hence, the length of are JL is $(25)/(18) \pi$ so option c is correct.

What is -24/-11 simplified?

Answers

Answer:

2.18 repeating.

Step-by-step explanation:

So it will be 24/11 because the negatives cancel out each other. So the answer is 2.18 repeating.

The simplified answer is 24/11 because you can cancel out both negatives as a negative divided by a negative is a positive. The answer in decimal form is 2.181818...

What is 0.78 divided by 3.51??? (Decimals)

Answers

0.78/3.51 = 0.222
The 0.222 repeats on forever, but writing it to the thousandths spot is generally an acceptable spot to stop writing the repeating number. If you're writing it on paper, put a line above the last number (or sets of numbers) that repeats. So, in this case, the last 2 in 0.222 would have a line above it, kind of like an upside-down underline, I guess.

Jeff buys a jelly cake for $25. The store increases its purchase price by 200%. What is the new price for the jelly cake

Answers

The new price for the jelly cake is $75 as the store increases its purchase price.

What is percentage?

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.

The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

Initial price of jelly cake is = $25.

Increase in price of jelly cake is = 200%.

Hence, increase in price of jelly cake is = $25 × 20%

= $25 × (200/100)

= $25 × 2

= $50.

Hence, the new price for the jelly cake is = initial price + increase in price

= $25 + $50

= $75.

Therefore, the new price for the jelly cake is $75.

x/25=200/100
solve the porportion to find hat x=$50, this value is the increase in cost whichneeds to be added to the original cost of $25.00

So the new price of the jelly cake is $25+$50=$75.00

What is the sum of the measures of the exterior angles of this triangle?A triangle has angles A, C, 51 degrees. Angle A has exterior angle B and angle C has an exterior angle with measure of 112 degrees.

Answers

The measure of ∠B is 119°.

What is the exterior angle?

An exterior angle is a measure of rotation between one extended side(we extend it virtually) of the polygon with its adjacentside which is not extended.

All the exteriorangles are of the same measure, and therefore, their measure is (360/n)°.

The angle adjacent to 112° will form a straight angle along with 112° adding to 180° which makes ∠C=68°

Then;

a+c+51°= 180°

a+68°+51° = 180°

a+119° = 180°

a = 180° - 119°

a = 61°

Now,

a+b = 180°

61+b = 180

b = 180-61
