Rectangle LOSP is shown below. The lengths, in units, of some of the line segments are also shown. Line segments MQ and NR are p
Galina-37 [17]

Answer: c. OSRN

Step-by-step explanation:

Sides of similar shapes are proportional.

For Rectangle LOSP,

Length = LO = 4+6+8 = 18 units

Width = OS= 12 units

Here, \dfrac{18}{12}=\dfrac{3}{2}  [proportionality constant]

a. For Rectangle LMQP,

Length = MQ = 12 units

Width = LM = 4 units

Here, \dfrac{12}{4}=3\neq\dfrac32

LMQP is not similar to LOSP.

b. Similarly, for LNRP,

Width = LN= 4+6 = 10

length = NR = 12

\dfrac{12}{10}\neq\dfrac32

LNRP is not similar to LOSP.

c. For OSRN,

Length = OS = 12

Width = ON = 8

\dfrac{12}{8}=\dfrac32

OSRN is similar to LOSP.

d. For MNRQ,

Length= NR = 12

Width = MN = 6

\dfrac{12}{6}=2\neq\dfrac32

MNRQ  is not similar to LOSP.

Hence, the shape similar to rectangle LOSP is OSRN.

The hyperbola is used as a mathematical model in which of the following areas?
Anna11 [10]

Answer:

Engineering

Step-by-step explanation:

Start by eliminating illogical choices:  dentistry, business, literature.

That leaves science and engineering.

Designs of suspension bridges usually include half parabolas or half hyperbolas, which indicates that engingeering is the logical choice here.

Science is discovery and understanding of the natural, physical world, whereras engineering is the application of knowledge and tools, of which space curves (such as hyperbolas) are one.

If holly,alex and ben had 100 balls. holly had 20 balls and alex had 2x as many as she did, how many did ben have?​
umka2103 [35]

Holly has 20 balls, and there are 100 balls in total.

So there are 100-20 = 80 balls left.

Alex had 2 * the amount Holly had, which is 20.

So Alex has 20 * 2 = 40 balls.

Together, they have 60 balls.

Which means 100-60 = 40. So Ben has 40 balls.

Check:

Holly: 20

Alex: 40

Ben: 40

Add them: 20 + 40 + 40 = 100
