Answer:

Both answers should be -2 and 14.

Step-by-step explanation:

Using the quadratic formula:

[tex]x^{2}-12x-28=0\\\\x=\frac{-(-12)+-\sqrt{(-12)^2-4(1)(-28)} }{2(1)}\\\\x= \frac{12+-\sqrt{144+112} }{2}\\\\x= \frac{12+-\sqrt{256} }{2}\\\\x= \frac{12+-16 }{2}\\\\x=6+-8[/tex]

Therefore:

[tex]x_{1} =6+8=14\\x_{2}=6-8=-2[/tex]

Answer:

15%

Step-by-step explanation:

1335-1200=135

9 months=9/12

135=1200 x r x 9/12

135=900r

divide each by 900

135/900       900r/900

0.15=r

0.15=15%

Step-by-step explanation:

[tex]\sqrt{10^{2} -8^{2} }[/tex] = 6

Answer:

b = 6

Step-by-step explanation:

Pythagorean formula:

a² + b² = c²

Work:

a² + b² = c²

8² + b² = 10²

64 + b² = 100

b² = 100 - 64

b² = 36

[tex]\sqrt{b^2} =\sqrt{36}[/tex]

b = 6

Answer:

20 gallons

Step-by-step explanation:

Divide 120 miles by 8 to find miles per gallon

120 ÷ 8 = 15 miles per gallon

Now divide 300 miles by 15 to find number of gallons required

300 ÷ 15 = 20

20 gallons are required for a journey of 300 miles

Answer:

x = 6

Step-by-step explanation:

Love proportions!

3x+2(x+6) = 35(21)

63x + 42 = 35x + 210

28x = 168

x = 6

Answer:

[tex]\huge\boxed{\text{Impossible}}[/tex]

Step-by-step explanation:

To find the probability of something happening, we find all the outcomes that can happen, find all the outcomes in which our criteria is met, and set that up as a fraction, where it's criteria met/total possible outcomes.

When we roll a 6-sided die, we will have 6 possible outcomes that we can roll.

1, 2, 3, 4, 5, and 6.

We can not roll anything except these 6! Since a die only has 6 sides, numbered 1-6, we will only roll these numbers.

7 is not in this list! It is impossible to roll a 7 on a die that only has 6 sides. Since 7 isn't even possible, it would be impossible to get a 7 on a 6-sided die.

Hope this helped!

A data set which could be represented by the box plot shown above include the following: B. 2, 3, 5, 5, 6, 7, 8, 8, 11.

In Mathematics, a box plot is sometimes referred to as a box-and-whisker plot and it can be defined as a type of chart that is used for the graphical or visual representation of the five-number summary of a data set with respect to locality, skewness, and spread.

By using the box-and-whisker plot (box plot) shown in the image attached above, the five-number summary for the given data set include the following:

By critically observing the box-and-whisker plots (see attachment), we can logically deduce that it represents all of the five-number summary for 2, 3, 5, 5, 6, 7, 8, 8, and 11.

Answer:

Its C.

Step-by-step explanation:

Answer:

x = 5

Step-by-step explanation:

Because the factor of the polynomial is x - 5, we can infer that the zero would be the solution of this equation: x - 5 = 0

Therefore, the zero is x = 5.

Answer:

Faye's probability of pulling out a white marble is 3/80.

Step-by-step explanation:

To find the probability, we must first add everything up.  10 + 13 + 16 + 10 + 11 = 60 marbles.  Now we divide 60 by the amount of white marbles there are.  60 ÷ 16 = 3.75% or 3/80.  Therefore, the probability of Faye pulling out a white marble is 3/80.

Answer:

5) r=40 gals/min

6) r= 125 mm/hr

7) $2600

8) d = 36 in

9) h= 1176 m

Step-by-step explanation:

5) r=v/r

r= 15,600 gals ÷ 390 mins

r= 40 gals/min

6) r=v/t

r= 1000mm ÷ 8 hrs

r= 125 mm/hr

7) $4500 - $1900 = $2600

8) C = Pi x d

c/Pi =d

113 in/3.14 = d

d = 36 in

9) Formula for h

h = 2 x a/b

h = 2 (84m2/12m)

h = 2 (7056/12)

h = 2(588)

h = 1176 m

Answer:

1 hour and 43 minutes or 103 minutes

Step-by-step explanation:

There are 60 minutes in an hour, so from 10 am to 11 am is 60 minutes. The additional 43 minutes need to be combined with the 60 minutes, which will give you 103 minutes.

Answer:

1 hour and 43 minutes

Step-by-step explanation:

10:00am+ 1 hour = 11:00 am

11:00 am + 43 minutes = 11:43

Answer: 67.5 cm

Step-by-step explanation:

Jason has 4 lengths of ropes

first is [tex]3\ in.\approx 7.5\ cm[/tex]

second is [tex]15\ cm[/tex]

Third is [tex]0.3\ m\approx 30\ cm\quad [\text{1 m = 100 cm}][/tex]

fourth is [tex]0.5\ ft\approx 6\ in.\approx 15\ cm\quad [\text{1 ft=12 in.}][/tex]

the total length of rope is the sum of four lengths

[tex]\Rightarrow 7.5+15+30+15=67.5\ cm[/tex]
