Sonja [21]

Answer:

Rational

Step-by-step explanation:

A surd is an irrational number. An irrational number refers to any number that can not be written in the form a/b where a and b are integers.

Given √3600, which can be written as √36 × √100 = 6 ×10 = 60.

Hence √3600 is a rational number.

The ages of three siblings combined is 27. The oldest is twice the age of the youngest. The middle child is 3 years older than t

kondaur [170]

Answer:

the oldest sibling is 12 years old.

The middle child is 9 years old.

The youngest child is 6 years old.

Step-by-step explanation:

Let the age of the youngest child be x

Then the oldest child will be 2x.

The middle child will be x + 3.

Since the combined age is 27;

x + 2x + x + 3 = 27

4x = 27 - 3

x = 24 / 4

x = 6

now 2x = 12 and x + 3 = 9

7x + 2y = 17<br>2x - 2y = 1<br>=

DerKrebs [107]

Answer:

$(2,\frac{3}{2}})$

Step-by-step explanation:

For finding the system of equations you can use one of two methods. There's the elimination method and also the substitution method. For this I think the best way we could go at solving this is by using the elimination method. Since we can eliminate the 2y. We can then solve for x and then we'll go from there.

$\left \{ +{{7x+2y=17} \atop {2x-2y=1}} \right. \\\\9x=18\\x=2$

Now that we know what x is we can substitute it for one of the equations and then we will be able to solve for y.

$7x+2y=17\\7(2)+2y=17\\14+2y=17\\2y=3\\y=\frac{3}{2}$

So now we have the x and the y and once we place them together we can get the solution of those two equations, and the solution is $(2,\frac{3}{2}})$ .

Raju, ramu and razi can do a piece of work in 20, 30 and 60 days respectively depending on their capacity of doing work. If raju

jok3333 [9.3K]

If Raju is assisted by Ramu and Razi every third day, then the number of days in which Raju will complete the work is 15 days.

<h3>What is Division?</h3>

The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

Let the total unit of work be 60 units.

Given that Raju, Ramu, and Razi can do a piece of work in 20, 30, and 60 days respectively. Therefore, the rate at which three of them works can be written as,

Rate = Total Work/ Time

Rate of Raju = 60 units /20 days = 3 units per day

Rate of Ramu = 60 units /30 days = 2 units per day

Rate of Razi = 60 units /60 days = 1 units per day

The work completed on the first day will be,

Work completed = Rate × Time

= Rate of Raju × 1 day

= 3 units per day × 1 day

= 3 units

The work completed on the second day will be,

Work completed = Rate × Time

= Rate of Raju × 1 day

= 3 units per day × 1 day

= 3 units

The work completed on the third day will be,

Work completed = Rate × Time

= (Rate of Raju+ Rate of Ramu + Rate of Razi) × 1 day

= (3+2+1) units per day × 1 day

= 6 units

Therefore, every three days, 12 units every three days of work will be completed. Therefore, the number of times three of them need to work together is,

Number of times = 60 units / 12 units every three days = 5

Further, the number of days if they meet 5 times is,

Number of days = 3 × 5 = 15

Hence, If Raju is assisted by Ramu and Razi every third day, then the number of days in which Raju will complete the work is 15 days.

LenaWriter [7]

Answer:

Step-by-step explanation:

using pythagoras theorem

a^2 + b^2 = c^2

B^2 + 8^2 = 15^2

B^2 + 64 + 225

B^2 = 225 - 64

B^2 = 161

B = $\sqrt{161}$ OR 12.7
