The ratio of peppermint to chocolate is 5:3 and the ratio of peppermints to gummies is 3:4. What so the ratio of chocolates to g
Liula [17]
Peppermint to chocolate is 5:3, so5p=3c, and peppermints to gummies is 3:4, so 3p = 4g.

5p = 3c
*3     *3

15p = 9c
---------------
3p = 4g
*5      *5
15p = 20g
---------------
15p = 9c
15p = 20g
9c = 20g, so chocolates to gummies is 9:20.

Find the surface area of the rectangular prism. justify your answer 3ft, 2ft, 4ft
Gelneren [198K]

Answer: SA=52\ ft^2

Step-by-step explanation:

The surface area of a rectangular prism can be calculated with the following formula:

SA = 2wl + 2lh + 2hw

Where "l" is the length of the rectangular prism, "w" is the width and "h" is the height.

In this case you can say that the length, the width and the heigth of this rectangular prism, are the following:

l=4\ ft\\\\w=2\ ft\\\\h=3\ ft

Knowing these values, you can substitute them into the formula shown before:

SA = 2wl + 2lh + 2hw\\\\SA = 2(2\ ft)(4\ ft) + 2(4\ ft)(3\ ft)+ 2(3\ ft)(2\ ft)

Finally, you must evaluate in order to calculate the surface area of the rectangular prism.

You get that this is:

SA=2(8\ ft^2)+2(12\ ft^2)+2(6\ ft^2)\\\\SA=16\ ft^2+24\ ft^2+12\ ft^2\\\\SA=52\ ft^2

Please help me with questions 27 and 28
kondor19780726 [428]
Answer to Problem 27 is choice D) (x,y) --> (x+3, y-5)
Answer to Problem 28 is choice A) collinear

------------------------------------------------------------

Explanation for problem 27: Focus on point G. Notice how we shift it 4 units to the right and then 5 units down. So that's why the rule is (x,y) --> (x+3, y-5)

Explanation for problem 28: The term "collinear" means all points fall on the same line. Or put another way, its possible to draw a single straight line through all the points. The term "co" means "share" and "linear" means "line". So "collinear" translates to "sharing the same line". One axiom is that two points are always collinear no matter how you place them. Any more than 2, its not always guaranteed.
