Which statements are true regarding the prism ?

DochEvi [55]

Answer:

Step-by-step explanation:The prism has 9 edges; the bases of the prism are triangles; and the prism has 5 faces.

Step-by-step explanation:

The bases of a prism are the faces that are parallel. In this prism, the only faces that are parallel are the two triangles. This means the bases are triangles.

In addition to the two parallel bases, there is a are three faces that join the sides of the bases. This makes a total of 2+3 = 5 faces.

The edges are where the faces meet. There are 3 edges around each base; this is 6. There are also 3 edges connecting the lateral faces; this makes 6+3 = 9 edges.

What is the solution to this system of linear equations? 12q + 3r = 15 –4q – 4r = –44 (–18, 29) (–2, 13) (8, –1) (15, –44)

Akimi4 [234]

12q +3r =15
3(4q +r) = 3*5
Divide both sides by 3
4q +r = 5
Time for the second one:
-4q -4r = -44
-4(q +r) = (-4)*11
Divide both sides by -4
q +r = 11
4q +r = 5
q +r = 11
Subtract the second from first equation
3q 0 = -6
3q = -6
q = -6/3 = -2
q = -2
q +r = 11
-2 +r =11
r = 11 +2
r = 13
q = -2
r = 13
Your answer is...
(-2,13)

Original price: $63.00 new price: $56.07 arrowright original price: $37.50 new price: $34.50 arrowright original price: $12.25 n

melisa1 [442]

Part a: There is an 11% decrease in the price

Part b: There is an 8% decrease in the price

Part c: There is an 8% increase in the price

Part d: There is an 11% increase in the price

Part a:

Original price = $63

New price = $56.07

Change in price = 56.07-63 = - 6.93

Percentage change in price = Change in price/Original price*100

= -6.93/63*100

= - 0.11*100 = 11% decrease in price

Part b:

Original price = $37.50

New price = $34.50

Change in price = 34.5-37.5 = - 3

Percentage change in price = Change in price/Original price*100

= -3/37.5*100

= - 0.08*100 = 8% decrease in price

Part c:

Original price = $12.25

New price = $13.23

Change in price = 13.23-12.25 = 0.98

Percentage change in price = Change in price/Original price*100

= 0.98/12.25*100

= 0.08*100 = 8% increase in price

Part d:

Original price = $98

New price = $108.78

Change in price = 108.78-98 = 10.78

Percentage change in price = Change in price/Original price*100

= 10.78/98*100

= 0.11*100 = 11% increase in price
