You would measure the Fish tank in centimeters

Because pools are normally very large, you would use a larger unit, like meters, to measure it. Fish tanks are usually a lot smaller than pools, so you would use a smaller unit to measure them, like centimeters.
Your answer is a fish tank.

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.

How to solve this system of equation 3x + y= 17 and 4x + 2 y = 20

lana66690 [7]

3x + y= 17 (a)
4x + 2 y = 20 (b)

Multiply (a) by 2:

6x + 2y = 34 (a)
4x + 2y = 20 (b)

make: (a) - (b)

2x = 14 -----> x =7

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

Replace the value of x = 7 in one of anterior equation:

3x + y= 17
3 x 7 + y = 17
21 + y = 17
y = 17 - 21
y = -4

Sarah hiked a path that took her from 34 feet below sea level to 52 feet above sea level . What was the change in her elevation?

Ugo [173]

Answer:

86 ft

Step-by-step explanation:

First method: Logical thinking

Think of the position 34 ft below sea level as -34.

The position above sea level is 52.

You need to find the distance between -34 and 52.

You go from 34 ft below sea level, -34 to 0. That is 34 ft.

Then you go from sea level, 0 ft, to 52 ft above sea level. That is 52 ft.

The total is 34 ft + 52 ft = 86 ft

Answer: 86 ft

Second method: Calculate a distance in math

The distance between two points on a number line is the absolute value of the difference of their coordinates. The coordinates are -34 and 52. Subtract the numbers in either order, and take the absolute value of the difference.

|-34 - 52| = |-86| = 86

If you did it in the other order, you'd get the same answer.

|52 - (-34)| = |52 + 34| = |86| = 86

Answer: 86 ft
