C because it has the x variables in the numerator. This is wrong because the x axis represents horizontal movement and slope is rise over run, not run over rise

$\text {Laura = } 12 \text { years } 3 \text { months }$

$\text {Lisa = } 11 \text { years } 7 \text { months }$

$\text {Deborah = } 11 \dfrac{1}{2} \text { years } = 11 \text { years } 6 \text { months }$

$\text {Elizabeth = } 11 \dfrac{1}{3} \text { years } = 11 \text { years } 4 \text { months }$

-----------------------------------------------------
Find Total :
-----------------------------------------------------
$\text {Total = } 12 \text { yr } 3 \text { mth } + 11 \text { yr } 7 \text { mth } + 11 \text { yr} 6 \text { mth} +11 \text { yr } 4 \text { mth}$

$\text {Total = } 45 \text { years } 20 \text { months }$

-----------------------------------------------------
Find Average :
-----------------------------------------------------
$\text {Average = } (45 \text { years } 20 \text { months }) \div 4$

$\text {Average = } 560 \text { months } \div 4$

$\text {Average = } 140 \text { months } \div 4$

$\text {Average = } 11 \text { years } 8 \text { months }$

----------------------------------------------------------------------------------------------------------
$\bf \text {Answer : Average = } 11 \text { years } 8 \text { months }$

If the number of bacteria in a

Y_Kistochka [10]

Answer:

The population of 75 hours from now would be 40,000.

Step-by-step explanation:

The reason for this is because your initial number is 10,000 and when 25 hours pass by, your population would be 20,000. Another 25 hours pass by, and then your population would be 40,000. If you multiply 25 by 3, you will notice 75 hours have just passed, so your answer would be 40,000.

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.
