A plane slices diagonally through a rectangular prism as shown. Which term best describes the cross-section formed by the inters

joja [24]

Answer:

Rectangle shaped cross section is formed by intersection of plane and prism.

Step-by-step explanation:

Given: A rectangular Prism.

To find: Shape of Cross Section when a plane intersect the prism diagonally

A plane intersect the Rectangular prism .i.e, Cuboid diagonally which means plane passes from top edge of cuboid to edge on bottom on opposite side.

Figure is attached.

In this way we get a Rectangular shaped Cross section which includes edges of cuboid and diagonals of the side faces.

Therefore, Rectangle shaped cross section is formed by intersection of plane and prism.

Express the area of a 30 60 90 triangle as a function of the length h of the hypotenuse

Tasya [4]

In a 30-60-90 degree triangle, the ratio of the side lengths is 1:√3:2
if the hypotenuse is h, the legs are h/2 and h/√3 respectively
the area is (1/2)(h/2)(√3h/2)=√3h²/8

You flipped a coin 50 times and got 23 heads.What is the experimental probability of getting a head? Write your answer as a frac

Studentka2010 [4]

Answer:

$\frac{23}{50}=0.46=46$ %

Step-by-step explanation:

Experimental probability is the actual odds produced from an event. Probability is typically expressed as a fraction of the number of desired outcomes (numerator) over the total number of outcomes (denominator). In this case, the desired outcome is getting heads on a coin flip (23) and the total outcomes is the number of times you flipped the coin (50). Represented as a fraction:

$\frac{23}{50}$

Divide numerator by denominator to get a decimal: 23÷50 = 0.46

Multiply the decimal by 100 to get a percent: 0.46 x 100 = 46%
