Answer:

A square root of a number is a value which we get by multiplying a number of itself

Step-by-step explanation:

A square root of a number is a value that, when multiplied by itself, gives the number. Example: 4 × 4 = 16, so a square root of 16 is 4. Note that (−4) × (−4) = 16 too, so −4 is also a square root of 16. The symbol is √ which always means the positive square root. Example: √36 = 6 (because 6 x 6 = 36)

There are 5 red marbles, 8 blue marbles, and 12 green marbles in a bag. What is the theoretical probability of randomly drawing

Zigmanuir [339]

So first we add up all the marbles. Which would be 25. Then we look to see how many red marbles there are. There are 5. You have a 5/25 chance of drawing a red marble. But you can reduce that. So when it's all said and done you have 1/5 chance of drawing a red marble.
Hope this helps!

Amelia is 3 years younger than Etta. The product of their ages is 40. How old is Amelia?

Paul [167]

Answer:

Amelia is <u>5 years</u> old

Let x be Amelia and y by Etta.

[] Amelia is 3 years younger than Etta.

x = y - 3

[] The product of their ages is 40.

x * y = 40

We can use a system of equations to solve

[] The system

a = e - 3

a * e = 40

[] Graphing

-> See attached

[] The answer is 5

Find the missing variable for a parallelogram:

Arada [10]

Answer:

Height of parallelogram = 5.07 inches

Step-by-step explanation:

We are given Area of Parallelogram = 32 in^2

Height of Parallelogram = ?

Base of Parallelogram = 6.3 in

The formula to find the Area of Parallelogram is:

Area of Parallelogram = Base * Height

32 = 6.3 * Height

=> Height = 32/6.3

=> Height = 5.07 inches

So, height of parallelogram = 5.07 inches

The radius of a cylindrical vessel is 7 cm and height is 1400 m . Find the cost of painting its inner curved surface area at the

Olegator [25]

Answer:

Cost = 616000 DHS per square centimetre.

Step-by-step explanation:

curved surface of a cylinder = 2 $\pi$ rh

r = 7 cm

h = 1400 m = 140000 cm

The outer curved surface area of the cylinder = inner curved surface area of the cylinder

The inner curved surface of the cylinder = 2 $\pi$ rh

= 2 x $\frac{22}{7}$ x 7 x 140000

= 2 x 22 x 1 x 140000

= 6160000

The inner curved surface of the cylinder is 6160000 square centimetre.

But, the cost of painting is at the rate of 10 DHS per square centimetre.

The inner curved surface of the cylinder = 6.16 x $10^{6}$ square centimetre.

cost of painting the inner curved surface area = $\frac{6.16*10^{6} }{10}$

= 616000 DHS per square centimetre

The cost of painting the inner surface is 616000 DHS per square centimetre.
