What is the value of r to the nearest tenth?

Mathematics

5 0

Answer:

Hence r=10.3 cms (rounded to tenth place)

Step-by-step explanation:

In Triangle KLN ,

KN = 5 Cms

LN = ½ of LM

As the Perpendicular dropped from the center to the chord bisects it.

LM = 18 cm

LN = 9 cm

Now we have to find r or KL

We apply Hypotenuse Formula in this

The formula is given as

$c=\sqrt{a^2+b^2}$

Where c = r

a=5

b=9

Putting them in the formula

$r=\sqrt{5^2+9^2}$

$r=\sqrt{25+81}$

$r=\sqrt{106}$

$r=10.29$

The difference between rational and irrational

makvit [3.9K]

Answer:

Every integer is a rational number, since each integer n can be written in the form n/1. For example 5 = 5/1 and thus 5 is a rational number. However, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.

One pipe can fill a pool in 9 hours. Another pipe can fill the pool in 6 hours. How long would it take them to fill the pool if

kow [346]

Answer:

3.6 hours or 3 hours and 36 minutes.

Step-by-step explanation:

If the first pipe can fill the pool in 9 hours that means that in 1 hour it fills $\frac{1}{9}$ of the pool, we use the same logic for the second pipe and conclude that in 1 hour it feels up $\frac{1}{6}$ of the pool. If both were to fill the pool together that means that in 1 hour they would fill...
