3.5 belongs to which number sets

kompoz [17]

3.5 belongs to Rational number sets mainly and also belongs to Real Numbers.

<u>Step-by-step explanation:</u>

Number Sets are nothing but group of number classified into groups.

They are Natural, Whole, Integers, Rational, Irrational and Real numbers.

Natural number set = {1,2,3...},

Whole number set= {0,1,2,3...},

Integers = { ....-2, -1, 0, 1, 2, ....},

Rational numbers = { Integers, Decimals, Fractions},

Irrational numbers = { non fractional numbers eg: π, $\sqrt{2}$ etc.}

Real = { Natural, Whole, Integers, Rational, Irrational }.

Any number which is a fraction resulting in a decimal value is Rational Number sets.

3.5 is a decimal number so it can be Rational Number sets also Real Number sets.

Answer:

The height of the lamp post is 15 feet ⇒ 1st answer

Step-by-step explanation:

The ladder , the lamp post and the ground formed a right triangle, the length of the ladder is its hypotenuse (l), the height of the lamp post (h) and the horizontal distance on the ground between the base of the ladder and the base of the lamp post (d) are the legs of the triangle

By using Pythagoras Theorem ⇒ <em>the square of the hypotenuse is equal to the sum of the squares of the other two legs</em>

∵ l² = h² + d²

∵ The length of the ladder is 25 feet

∴ l = 25

∵ The ladder is placed 20 feet from the lamp post

- That means the distance between the base of the ladder and

the base of the lamp post on the ground

∴ d = 20

- Substitute the values of l and d in the Pythagoras formula

∵ (25)² = h² + (20)²

∴ 625 = h² + 400

- Subtract 400 from both sides

∴ 225 = h²

- Take √ for both sides

∴ 15 = h

∴ The height of the lamp post is 15 feet

Hector had 30 minutes to do a three-problem quiz. He spent 11 3 4 minutes on question A and 6 1 2 minutes on question B. How muc

stich3 [128]

Answer:

$11 \frac{3}{4}$ min

Step-by-step explanation:

In order to solve this problem, we must subtract the times he has already used from the time he has available, so we get:

$30-11 \frac{3}{4} - 6 \frac{1}{2}$

we can start solving this subtraction by turning all of the numbers into improper fractions so we get:

$\frac{30}{1}-\frac{11*4+3}{4}- \frac{6*2+1}{2}$

$\frac{30}{1}-\frac{47}{4}- \frac{13}{2}$

next, we can find a least common denominator. In this case it will be 4, so we need to turn all denominators into a 4, so we get:

$\frac{30*4}{1*4}-\frac{47}{4}- \frac{13*2}{2*2}$

$\frac{120}{4}-\frac{47}{4}- \frac{26}{4}$

and now we can subtract the numerators and copy the denominators so we get:

$\frac{120-47-26}{4}$

$\frac{47}{4}$

which can now be turned into a mixed number by dividing 47/4 which yields 11 with a remainder of 3, so the mixed number is:

$11 \frac{3}{4}$ min

and this is the amount of time he has available to solve the las problem.

Donovan broke the 100m sprint world record at the olympics within 9.84s in contrast a dog runs at a speed of 30km per hour .If t

Free_Kalibri [48]

<h2>Answer:</h2>

No the dog cant catch up with Donovan

<h3>Step-by-step explanation:</h3>

30km to meters is 30000

30000 meters divided by 60 to to get how many meters per second

= 500 a dog travels 500 meters per minute

100m divided by 9.87 = 10.1 meters per second

500 divided by 60 = 8.3 meters per second

Donovan can run faster than the dog by 1.8 meters per second
