Marci needs to rent a storage unit. She needs to determine the volume of the storage unit to decide if the storage unit is big e

stealth61 [152]

Answer:

$Volume = 176ft^3$

Step-by-step explanation:

Given

$Height = 8$

See attachment for base dimension

Required

Determine the volume of the storage unit

From the attachment, we can split the base dimension into two rectangles.

CDEF and ABCG

And the dimensions are:

CDEF

$EF = CD = BD - BC = 5 - 2 = 3$

$ED = FC = FG +AB = 4 + 2 =6$

So, the area of CDEF is:

$Area = EF * ED$

$Area = 3 * 6$

$Area = 18$

ABCG

$AB= GC = 2$

$AG = BC = 2$

$Area = AB * AG$

$Area = 2 * 2$

$Area = 4$

So, the base area is:

$Base\ Area = 18 + 4$

$Base\ Area = 22$

The volume is then calculated as:

$Volume = Base\ Area * Height$

$Volume = 22 * 8$

$Volume = 176$

What is the solution for 5x^2-x+6=0

kati45 [8]

The easiest way to solve this problem is by using the Pythagorean theorem :D

Pythagorean theorem: [-b +- sqrt(b^2 - 4ac)]/2a

5 = a

-1 = b

6 = c

therefore, by plugging these values in!

[-(-1) +- sqrt((-1)^2 - 4(5)(6))]/2(5)

[1 +- sqrt(1 - 120)]/10

Oh so we're using imaginary numbers, so in this case you'll need to know that i = sqrt(-1), so keep this in mind (I can see why this was so difficult)

[1 +- sqrt(119)*i]10

answers:

( 1 + i*sqrt(119) ) / 10

( 1 - i*sqrt(119) ) / 10

lisov135 [29]

Answer:

cohort study

Step-by-step explanation:

Given that an investigator reviewed the medical records of 200 children seen for care at Boston Medical Center in the past year who were between the ages 8 and 12 and identified 40 children with asthma. He also identified 40 children of the same ages who were free of asthma. Each child and their family were interviewed to assess whether there might be an association between certain environmental factors such as exposure to second-hand smoke.

The objective of this experiment is to test the causes of the disease asthma and to find the risk factors and environment causing this disease.

So this cannot come under randomized control nor case control.

Cross over study is to put to two different environments two groups and study. But here nothing is influenced actual environments are studied

Hence this comes under cohort study

The LCM of the given numbers have been determined.

LCM stands for Least Common Multiple .

For two numbers , LCM is the number that is the smallest number of which they both are a factor.

It is asked to determine

LCM of 6 and 9

6 = { 6 , 12 , 18 , 24 , 30 , 36 , 42 .....}

9 = { 9 , 18 ,27 .....}

The LCM of 6 , 9 is 18

LCM of 8 and 12

8 = { 8,16,24,32....}

12 = {12 , 24 ,36....}

The LCM of 8 and 12 is 24

LCM of 4 , 6 and 8

4 = {4 , 8 , 12 , 16 , 20,24,28 ....}

6 = { 6 ,12 ,18,24......}

8 = {8 , 16,24 .....}

The LCM of 4,6 and 8 is 24

The LCM of 6 and 15 is 30

The LCM of 20 and 30 is 60

The LCM of 25,30 and 75 is 150

The image of the solution is attached .
