2/8
Step-by-step explanation:
because there are 2 blue marbles
add those up with the red marbles(6) and you get 8 marbles. But the chance for picking up a blue marble would be 2/8
Answer:
Step-by-step explanation:
The Area of a Square is the square of the measure of one side of the square.
Hence, given the expression for the area of a square, express the given area as the square of an expression to get the measure of one side.
The given expression is:
Rewrite the expression as:
Recall the binomial expansion:
Substituting a=10x and b=8, it follows that the expression becomes:
Since the area of a square is the square of the measure of one side, it follows that the measure of one side from the given expression is 10x-8.
Answer:
The cross-section of the rectangular prism is a:
Step-by-step explanation:
When you take a cross-section of a rectangular prism, regularly <u>you will obtain a rectangle because this was the base or the two-dimension figure that was used to form the three-dimension figure, in this case, the rectangular prism</u>, the form of obtaining other figure is using how reference the square face, in that case, the cross-section would be a square, this happens because the cross-section is bind with the reference face. Possibly you think the cross-section in the figure doesn´t appear a rectangle, <u>this happens by the perspective because we are looking at the rectangular prism with an inclination of 45°, but if the inclination was 90°, you would see a blue rectangle</u>.
