Alright! So the easiest way for me personally is to make the fraction over a number like 10 or a 100. So... for 5/20, I would multiply both numbers by 5. That gives you 25/100.

Then you could just divide.

Hope that makes sense! Let me know if you any more help!!

Answer:

Part a) Rectangle

Part b) Triangle

Step-by-step explanation:

Part A) A cross section of the rectangular pyramid is cut with a plane parallel to the base. What is the name of the shape created by the cross section?

we know that

When a geometric plane slices any right pyramid so that the cut is parallel to the plane of the base, the cross section will have the same shape (but not the same size) as the base, So, in the case of a right rectangular pyramid, the cross section is a rectangle

Part b) If a cross section of the rectangular pyramid is cut perpendicular to the base, passing through the top vertex, what would be the shape of the resulting cross section?

we know that

Cross sections perpendicular to the base and through the vertex will be triangles

Answer:

x = $200

The original price is $200

Question :

The price of a dress is reduced by 50%. When the dress still does not sell, it is reduced by 50% of the reduced price. If the price of the dress after both reductions is $50, what was the original price?

Step-by-step explanation:

Let x represent the original price of the dress.

First reduction

After first reduction the value of the price is given as;

p1 = x - 50% of x = (1-0.50)x = 0.5x

p1 = 0.5x

Second reduction

After the second reduction the value of the price is given as;

p2 = p1 - 50% of p1 = (1-0.50)p1 = (0.50)0.50x

p2 = 0.25x .....1

Since, p2 is given

p2 = $50

Substituting into equation 1

$50 = 0.25x

x = $50/0.25 = $200

x = $200

The original price is $200

Which expression is equivalent to 18 − 20?

Sveta_85 [38]

The answer is 18+(-20) because if if you were going to solve that equation you would use the absolute value of -20 and then the opposite of the sign giving you 18-20. Hope this helps:)

Richard deposits $237.95 every month into his mortgage. At the end of 30 years, he has a balance of $183,710.77. What interest h

77julia77 [94]

Answer:

$98,048.77

Step-by-step explanation:

First you want to find out how much he has put in without interest so you would do 237.95*12 to figure out how much he puts in per year then times that number by 30 to figure out how much he has put in in total, after this you subtract this total from the 183,710.77 to get the total amount of interest
