Answer:

true.

A chord that passes through the center of a circle is called a diameter and is the longest chord.

Step-by-step explanation:

A diameter satisfies the definition of a chord, however, a chord is not necessarily a diameter. This is because every diameter passes through the center of a circle, but some chords do not pass through the center. Thus, it can be stated, every diameter is a chord, but not every chord is a diameter.

i hope this helps you. :)

One leg of a right triangle has a length of 5m. The other sides have lengths that are consecutive integers. Find these lengths.

pickupchik [31]

The lengths of the other two sides of the right triangle are 12 and 13

<h3>Pythagorean theorem </h3>

From the question, we are to determine the lengths of the other sides of the triangle

From the given information,

The other sides have lengths that are consecutive integers

Thus,

If the length of the other side is x

Then,

The hypotenuse will be x + 1

By the <em>Pythagorean theorem</em>, we can write that

(x+1)² = x² + 5²

(x+1)(x+1) = x² + 25

x² + x + x + 1 = x² + 25

x² - x² + x + x = 25 - 1

2x = 24

x = 24/2

x = 12

∴ The other leg of the right triangle is 12

Hypotenuse = x + 1 = 12 + 1 = 13

Hence, the lengths of the other two sides are 12 and 13

A fish tank in a pet store has 23 fish in it. 10 are orange and 13 are white. Determine the probability that if we select 4 fish

Gala2k [10]

Answer:

ok so the probility of gettting one white fish is

13/23

and if we take out one white fish the problity is

12/22

so we just multiply

12/22*13/23=0.30830039525

so the problity is 0.30 if you choose two fish you will get white for both

An airline weighed the carry-on luggage of all its

nikklg [1K]

Using the graph, it is found that 976 passengers had carry-on luggage that weighed less than 20 lb.

<h3>Graph:</h3>

The graph is not given in this problem, but an internet search indicates that the information it contains is as follows:

120 passengers carry luggage of 4 lb or less.

222 passengers carry luggage between 5 lb and 9 lb.

378 passengers carry luggage between 10 lb and 14 lb.

256 passengers carry luggage between 15 lb and 19 lb.

90 passengers carry luggage between 20 lb and 24 lb.

40 passengers carry luggage between 25 lb or more.

Hence, the number of passengers with luggage below 20 lb is:

$120 + 222 + 378 + 256 = 976$

976 passengers had carry-on luggage that weighed less than 20 lb.

What is the area of triangle ABC Round to the nearest

scoray [572]

Answer:

$A=61.8\ units^2$

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The area of triangle ABC applying the law of sines is equal to

$A=\frac{1}{2}(AC)(BC)sin(C)$

substitute the given values

$A=\frac{1}{2}(10)(13)sin(72^o)$

$A=61.8\ units^2$
