Expand and simplify 3(5x + 2) +2(x-1)

Answer: The answer is 91.44 centimeters/cm

Step-by-step explanation:

2.54*36= 91.44 centimeters/cm

A 36-inch long measuring stick is equivalent to 91.44 cm.

To convert inches to centimeters, we can use the conversion factor:

1 inch = 2.54 cm

To find out the length of a 36-inch measuring stick in centimeters,

we multiply the length in inches by the conversion factor:

36 inches x 2.54 cm/inch

= 91.44 cm

Therefore, a 36-inch long measuring stick is equivalent to 91.44 cm.

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = \frac{2}{45} }}}}}[/tex]

Step-by-step explanation:

[tex] \sf{ - 5 = \frac{ - 2}{9x} }[/tex]

Apply cross product property

[tex] \dashrightarrow{ \sf{ - 5 \times 9x = - 2}}[/tex]

[tex] \dashrightarrow{ \sf{ - 45x = - 2}}[/tex]

Divide both sides by -45

Answer:

100 meters

Step-by-step explanation:

Given the following :

Alex house = F

Alex school = H

Alex bus stop = G

FG = 2x meters

GH = 1000meters

FH = 1200 meters

Hence,

FH = FG + GH

1200 = (2x + 1000) meters

1200 = 2x + 1000

1200 - 1000 = 2x

200 = 2x

x = 100meters

Hence, x = 100 meters

Answer:

A single sheet of paper should weigh: 0.00645 pound or  [tex]6.45*10^{-3}[/tex] (in scientific notation)

Step-by-step explanation:

Divide 3.225 (the weight of the ream of paper) by 500 (the amount of paper in a ream).

If you need the scientific notation form, simply move the decimal point/place right or left until you end up with a whole number that is between 1 and 10 (in this case, 3 times to the right), then determine what power of 10 it should be, depending on the number of times you moved the decimal place (in this case, the power is -3).

The power/exponent is determined by the direction you have to move your decimal point, right=negative and left=positive. For example, if you started off with the number 6450, you would move the decimal point 3 times to the left and your power would be positive 3, which results in [tex]6.45*10^{3}[/tex].

Mean=sum of observations/number of observations

=>17+15+5+8+20/5

=>65/5

=>13

Answer:  14.2

Step-by-step explanation:

The numbers are 17,15,5,8,20, and 20   and to find their mean you need to find their average which their sum divide by the number of values.

17 + 15 + 5 + 8 + 20 + 20 = 85

85 /6 = 14.1666...  and rounded to the nearest tenth is 14.2

Answer:

Answer:

Step-by-step explanation:

The sum of suplementary angles is allways 180°

so:

x  -   the other angle

3x  - three times the other angle

180°- x  - one angle

180° - x + 184° = 3x

   364° = 4x

     x = 91°

180°- x = 180° - 91° = 89°

Answer:

Step-by-step explanation:

Simplify the following:

(5 i + 4) (-5 i + 4)

Hint: | Multiply 4 + 5 i and 4 - 5 i together using FOIL.

(4 + 5 i) (4 - 5 i) = (4) (4) + (4) (-5 i) + (5 i) (4) + (5 i) (-5 i):

4×4 + 4 (-5 i) + 5 i×4 + 5 i (-5 i)

Hint: | Multiply 4 and 4 together.

4×4 = 16:

16 - 5×4 i + 5 i×4 + 5 i (-5)×i

Hint: | Multiply 4 and -5 together.

4 (-5) = -20:

16 + -20 i + 5 i×4 + 5 i (-5)×i

Hint: | Multiply 5 and 4 together.

5×4 = 20:

16 - 20 i + 20 i + 5 i (-5)×i

Hint: | Combine products of like terms.

5 i (-5)×i = 5 i^2 (-5):

16 - 20 i + 20 i + -5×5 i^2

Hint: | Evaluate i^2.

i^2 = -1:

16 - 20 i + 20 i - 5×5×-1

Hint: | Multiply 5 and -1 together.

5 (-1) = -5:

16 - 20 i + 20 i - 5-5

Hint: | Multiply -5 and -5 together.

-5 (-5) = 25:

16 - 20 i + 20 i + 25

Hint: | Evaluate 16 - 20 i + 20 i + 25.

16 - 20 i + 20 i + 25 = 41:

Step-by-step explanation:

A logarithm is a mathematical operation that determines how many times a certain number, called the base, is multiplied by itself to reach another number. ... Logarithms even describe how humans instinctively think about numbers.

Answer:

A logarithm tells what exponent (or power) is needed to make a certain number, so logarithms are the inverse (opposite) of exponentiation. Just as an exponential function has three parts, a logarithm has three parts. The three parts of a logarithm are a base, an argument (also called power) and an answer.

Answer: D

Step-by-step explanation:

We will try it to determine how much the need to save using the exponential function. In an exponential function,we need the start up amount and the common difference.

We know that the common difference is is 1.085  because if they will earn 8.5% interest plus 100% .

So  1.085 raised to the number of years times a number has to equal 250,000

x * 1.085^14 = 250,000   now solve for x

3.13340357495x = 250,000

x = 79785.44544 Rounded to the nearest cent is $79785.45

The given expression is x²+x.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

Add 1/4 to the given expression, we get

x²+x+1/4

= x²+x+(1/2)²

= (x+1/2)²

Verification:

x²+2.x.1/2+1/4

= x²+x+1/4

Therefore, 1/4 must be added to the given expression to make it a perfect-square trinomial.
