In a coin, there are 2 sides - heads and tails. The probability of getting a head is \frac{1}{2}

In a number cube, there are 6 numbers. The probability of being a number is 1.

The 6 numbers in a number cube are: 1, 2, 3, 4, 5, 6. There are 4 numbers less than 5. The probability of being less than 5 is \frac{4}{6}.

Now multiply the 3 probabilities together:

\frac{1}{2} \times \frac{1}{1} \times \frac{4}{6} = \frac{4}{12} \rightarrow \frac{1}{3}

Your answer is A.

A rectangular photograph is surrounded by a border that is 1 inch wide on each side. The total area of the photograph and the bo
My name is Ann [436]

if 1 inch is added, you would add 2 inches to to each side of rectangle.  

You would have: W+2, and, L+2,  

Now let W+2 = x and, L+2 = y  

Total area =  x*y=M  

If 1 inch is added again, like above you add 2 inches to both sides, you would then have:

(x+2)(y+2)=M+52;  

xy+2x+2y+4=M+52;  

xy=M

2x+2y=48  

x+y=48/2=24  

Now solve :

W+2+ L+2=24  

W+L=20  

The perimeter is 2(W+L)=20*2 = 40 inches.

Find the missing side of the triangle. Round your answers to the nearest tenth if necessary.
Alik [6]

Given:

In a right angle triangle, the measures of two legs are 5 ft and 5.6 ft. The measure of the hypotenuse is x.

To find:

The value of x.

Solution:

Pythagoras theorem: In a right angle triangle,

(Hypotenuse)^2=(Base)^2+(Perpendicular)^2

Using Pythagoras theorem, we get

(x)^2=(5)^2+(5.6)^2

x^2=25+31.36

x^2=56.36

Taking square root on both sides, we get

x=\sqrt{56.36}

x=7.50733

x\approx 7.5

The measure of missing side is 7.5 ft. Therefore, the correct option is D.

For a cube whole side lenght is 4 in , the expression 4 to the 3 could represent
S_A_V [24]

Answer:

Step-by-step explanation:

The volume of a cube.

The formula is V = s^3 where is the the "whole side length" of the cube. The cube requires three dimensions be multiplied together to find its volume.

That's why the formula is written as V = s^3. It means that V = s * s * s which is three sides multiplied together. They also need to be at right angles to each other.
