Write two mixed nubers that have the sum of 3

1 answer:

8 0

A mixed number is a number that is a whole number with a fraction
so numbers that are mixed are greater than 1

so therefor since both have to be greater than 1, the fractions have to add up to equal 1

so the mixed numbers are (1 and x) and (1 and y) where x+y=1 so some examples are
1 and 1/2+1 and 1/2
1 and 1/3+1 and 2/3
1 and 1/4 +1 and 3/4
1 and 1/1000+1 and 999/1000
etc

Find the missing side of a right triangle a b c

iren2701 [21]

Answer:

Use Pythagorean Theorem.

Step-by-step explanation:

To find any side of a right angled triangle, we use Pythagorean Theorem. It states that the square of hypotenuse is equal to the sum of squares of it's sides.

Let hypotenuse is a

Perpendicular is b

and base is c

According to the theorem:

a²= b² + c²

Add values and solve for the unknown variable / side.

If you had added the problem, I would have elaborated more but still this will help you out.

There are many cylinders with a height of 18 meters. Let represent the radius in meters and represent the volume in cubic meters

antiseptic1488 [7]

Answer:

Step-by-step explanation:

1). Equation that represents the volume of a cylinder,

V = πr²h

Here, r = radius of the cylinder

h = Height of the cylinder

2). Fromm the given formula of volume,

r(In m) V(In cubic meters)

1 56.55

2 226.19

3 508.94

3). If the radius is doubled from 1 m to 2 m,

At r = 1 m, Volume (V₁) = 56.55 m³

At r = 2 m, Volume (V₂) = 226.19

$\frac{V_2}{V_1}=\frac{226.19}{56.55}$

= 4

Therefore, volume is not doubled when radius of the cylinder is doubled.
