Which set of three number could represent the lengths of the sides of a right triangle? 7,9,11 8,15,17 12,18,22

MaRussiya [10]

8,15,17 represents

(17)^2=289

(15)^2=225

(8)^2=64

i.e. (17)^2=(15)^2+(8)^2

By converse of Pythagoras theorem

This ∆ is a right angled ∆

In a building there are 30 cylindrical pillars. The radius of each pillar is 42 m and height is 7 m. Find the total cost of pain

SashulF [63]

Answer:

The total cost of painting the curved surface area of all pillars at the rate of Rs 10 per square meter is Rs.554400.

Step-by-step explanation:

Given : In a building there are 30 cylindrical pillars. The radius of each pillar is 42 m and height is 7 m.

To find : The total cost of painting the curved surface area of all pillars at the rate of Rs 10 per square meter ?

Solution :

Radius of each pillar r= 42 m

Height of each pillar h= 7 m

The curved surface area of each pillar is $CSA=2\pi rh$

Substitute the value,

$CSA=2\times \frac{22}{7}\times 42\times 7$

$CSA=1848\ m^2$

Area of 30 pillars is given by,

$A=1848\times 30=55440\ m^2$

The curved surface area of all pillars at the rate of Rs.10 per square meter.

The cost painting is $C=55440\times 10=Rs.554400$

Therefore, the total cost of painting the curved surface area of all pillars at the rate of Rs 10 per square meter is Rs.554400.

You randomly select an integer from 0 to 9 (inclusively) and then randomly select and integer from 0 to 7 what is the probabilit

mezya [45]

<h3>Answer: 1/80</h3>

Reason:

Set A = {0,1,2,3,4,5,6,7,8,9}

Set B = {0,1,2,3,4,5,6,7}

The probability of getting a "2" from set A is 1/10 since there is one copy of "2" that we want out of ten values total.

The probability of getting a "2" from set B is 1/8 for similar reasoning. This time there are eight numbers in this set.

Multiply those fractions mentioned (1/10)*(1/8) = 1/80

This fraction converts to the exact decimal value of 0.0125, meaning there's exactly a 1.25% chance of getting "2" twice in a row.
