Step-by-step explanation:

Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.

Answer:

10 days.

Step-by-step explanation:

If you just multiply 5 days x 2 it doubles 25 liters which is pretty simple, and doesn't need to much explanation. I hope that helps :)

Answer:

42

Step-by-step explanation:

Answer:

96

Step-by-step explanation:

first you have to multiply your exponent which is 2 x 2 which is 4 then do the problem which is 18 + 6 = 24 x 4 = 96

Answer:

2 / 3 loads

Step-by-step explanation:

From. The plot, we can conclude that, the detergent that has the most bottles is that with 5 ; the number of cups in the detergent with 5 bottles is 12 cups

Number of cups used for each load of laundry = 18 cups

The loads of laundry Eric can do is thus :

Number of cups of detergent / number of cups used for each load of laundry

= 12 / 18

= 2 / 3 loads

Answer: C = 9

Step-by-step explanation:

Answer:

c=10.6

Step-by-step explanation:

In this we need to find c and we know that this is a right triangle

Therefore, I can use the Pythagorean Theorem which is a^2 + b^2 = c^2.

using this we then plug in a=8 and b=7 while c is the hypotenuse.

Now the equation is now 8^2 + 7^2 = c^2. We then solve for c.

8^2 + 7^2 = c^2

64 + 49 = c^2

113 = c^2

√113 = c

c = 10.630145...

Since the questions asks to round to the nearest tenth then the answer would be 10.6

"Theorem 106: If the slopes of two lines are opposite reciprocals of one another, or the product of their slopes is −1, then the lines are nonvertical perpendicular lines." - www.cliffsnotes.com

Answer:

9 Miles to be specific 8.95

Step-by-step explanation:

3 miles = 4.83 km

4.83 km = 4830 m

60 seconds X 45 =2700 Seconds

4830 divided by 2700 = 1.78 m/s

you want to know the distance so its speed X time

135 minutes X 60 seconds = 8100 secs

1.78 m/s X 8100 =14418 meters

14418 = 14.418 km

14.418 km = 9 miles

P.S. There is a shorter version but i think this is simpler for me and I use metric units.

Answer:

10

Step-by-step explanation:

Count from side to side. Point A to the arrow on the right, then point B to the arrow on the right, then point C to the arrow on the right, then point D, then point E. That's only one side, so double those five rays and you get ten (10). I was confused about this too at one point. You got this :)

Answer:

.

See the diagram attached below.

Let the chords be AB and AC with common point A.

AD is the diameter. Join B with D and C with D to form two triangles.

We need to prove that AB=AC.

\begin{gathered}In\ \triangle ABD\ and \triangle ACD;\\Given\ that\ \angle BAD=\angle CAD----(condition\ 1)\\since\ AD\ is\ diameter, \angle ABD=\angle ACD = 90^0\\So\ \angle ADB=\angle ADC--------(condition\ 2)\\AD=AD\ (common\ side)-----(condition\ 3)\\ \\So\ the\ triangles\ are\ congruent\ by\ ASA\ rule.\\Hence\ AB=AC.\end{gathered}

In △ABD and△ACD;

Given that ∠BAD=∠CAD−−−−(condition 1)

since AD is diameter,∠ABD=∠ACD=90

0

So ∠ADB=∠ADC−−−−−−−−(condition 2)

AD=AD (common side)−−−−−(condition 3)

So the triangles are congruent by ASA rule.

Hence AB=AC.

Answer:

The ratio of the perimeter of ABCD to JKLM is;

b. 3/5

Step-by-step explanation:

Given that ABCD ~ JKLM, where;

DC and ML are corresponding sides

AD and JM are corresponding sides

AB and JK are corresponding sides

Therefore;

DC/ML = AD/JM = AB/JK

Plugging in the values of the variables gives;

9/15 = z/10 = x/12

∴ z = 10×9/15 = 6

x = 12×9/15 = 7.2

9/15 = 6/y

y = 6 ×15/9 = 10

The perimeter of the quadrilateral ABCD = AB + BC + DC + AD

∴ The perimeter of the quadrilateral ABCD = 6 + 6 + 9 + 7.2 = 28.2

The perimeter of the quadrilateral JKLM = JK + JM + ML + LK

∴ The perimeter of the quadrilateral JKLM = 12 + 10 + 15 + 10 = 47

The ratio of the perimeter of ABCD to JKLM = 28.2/47 =0.6 = 3/5.

Answer: x= 5

Step-by-step explanation: subtract 2x from both sides eliminating 2x.

4x-64=-44 add 64 to both sides eliminating -64

4x=20  divide by 4  

20/4 = 5

4x/4 = x

x= 5

Hope this helps :)

Answer:

The Margin of Error in percentage is 5.88%

Step-by-step explanation:

The values of the factors in the question are;

The mean increase in price per share,  = $1.95

The number of companies in the sample, n = 100

The mean increase in price per share, [tex]\overline x[/tex] = $1.82

The standard deviation of the population, σ = $0.30

The margin of error, MOE, is given by the following formula;

[tex]Margin \ of \ Error= z \times \dfrac{\sigma}{\sqrt{n} }[/tex]

Where;

z = z-score, critical value = 1.96 at 95%

σ = The standard deviation of the population = $0.30

n = The sample size = 100

Therefore, we have;

[tex]Margin \ of \ Error= 1.96 \times \dfrac{0.3}{\sqrt{100} } = 0.0588[/tex]

The Margin of Error in percentage = 0.0588 × 100 = 58.8%

The Margin of Error in percentage = 5.88%

I know it LOL

Answer: 1) 8/15 2) 2 4/9 3) -13/45

Step-by-step explanation:

1/5 + 1/3 = 6/30 + 10/30 = 16/30 = 8/15

2 1/9 + 1/3 = 19/9 + 3/9 = 22/9 = 2 4/9

1/9 - 2/5 = 5/45 - 18/45 = -13/45
