Please Help Me ASAP A Right Rectangular Pyramid Is Sloed Vertically (down) At The Red Line By Aplane

Answers

Answer 1

The correct answer is C. Trapezoid.

What is a Trapezoid?

A trapezoid is a quadrilateral with at least one pair of parallel sides. It can have two parallel sides (a "parallel trapezoid") or none (a "non-parallel trapezoid").

The shape of the cross-section will depend on the orientation of the plane with respect to the pyramid. However, since the plane does not pass through the vertex of the pyramid, we know that the cross-section will not be a point or a line.

Assuming that the plane intersects all four triangular faces of the pyramid, the shape of the cross-section will be a trapezoid. Specifically, it will be a trapezoid with one pair of parallel sides (the bases) and two non-parallel sides (the legs) that meet at a common vertex.

Therefore, the correct answer is C. Trapezoid.

The Celluloid Cinema sold 290 tickets to a movie. Some of these are child tickets and the rest were adult tickets. A child ticket cost $8 and an adult ticket costs $8.5. If the cinema sold 2407.5 worth of tickets, determine how many child tickets and how many adult tickets were sold?

will give brainliest !

Answers

Answer:

child tickets: 115

adult tickets: 175

Step-by-step explanation:

number of child tickets = x

number of adult tickets = y

(value of child ticket [8] * number of child tickets [x]) + (value of adult ticket [8.5] * number of adult ticket [y]) = total value (2407.50)

8x + 8.5y= 2407.50

290 (total number of tickets) = x (number of child tickets) + y (number of adult tickets)

290 = x+y

system of equations: 8x + 8.5y= 2407.50

290 = x + y

solve equation:

x = 115

y = 175

Subtract 3 to bath sides: 2x=5-3 —> 2x=2
Then divide both sides by 2 to isolate the x: x=1

Answer:

1

Step-by-step explanation:

2x + 3 = 5

Subtract 3 on both sides to get the different values (variables, and numbers without variables) seperated.

2x + 3 - 3 = 5 - 3

2x = 2

Divide by 2 on both sides to isolate the variable

2x/2 = 2/2

x = 1

Check

Now that you have what "x" is (1) you can substitute that into the equation

2x + 3 = 5

2(1) + 3 = 5

2 + 3 = 5

5 = 5 CORRECT
