Answer:

[tex]\mathbf{3x}[/tex] is the greatest common factor for the expression: [tex]3x^2 -9x[/tex]

Step-by-step explanation:

We need to find the greatest common factor for the following expression: [tex]3x^2 -9x[/tex]

Greatest common factor is the number, that is divisible by both numbers. In the given expression 3x is the greatest number that is divisible by all the terms

[tex]3x^2 -9x\\3x(x-3)[/tex]

So, [tex]\mathbf{3x}[/tex] is the greatest common factor for the expression: [tex]3x^2 -9x[/tex]

Answer:

37.1 m/h, he was going over but I don't think 2 m/h is technically speeding

Step-by-step explanation:

v = 2√5(69)

v = 2 √345

v = 2 × 18.57418

v = 37.14835

v = 37.1 m/h

Answer: y-8=8/9(x-9)

Step-by-step explanation:

If it is parallel line that means that their gradient must be the same.

Point slope formula: y - y1 = m (x - x1)

m= gradient

y1 = y point

x1 = x point

y-8=8/9(x-9)

The percent of the total calories in each brownie that comes from fat is 26.9%

We know that the total amount of calories in each brownie is 420 calories, so that number represents our 100%, then we can write the relation:

420 cal = 100%

Now, the fat has 113 calories, this is a percentage X that we want to find, so we can write:

113 cal = X

We have the two relations:

113 cal = X

420 cal = 100%

If we take the quotient we get:

(113 cal/420 cal) = X/100%

Solving for X.

(113 cal/420 cal)*100% = X = 26.9%

So, the percent of the total calories in each brownie that comes from fat is 26.9%.

Step-by-step explanation:

The opportunity cost of playing football for Graham is $1,190.

The opportunity cost of certain activity in microeconomic theory is the value or gain given up by engaging in that activity in comparison to engaging in an alternative activity. Simply put, if you do a bone activity, you forfeit the potential to choose another.

Given that Graham made $1,100 during football season. Also, Graham spends about $9 on eating out after each game and his team plays a total of 10 games in a season.

Therefore, the opportunity cost of playing football for Graham is,

Opportunity cost

= Amount that Graham would have made in a part-time job +  Total cost of playing football season

= $1,100 + (Number of games × Amount spend in a single game)

= $1,100 + (10×$9)

= $1,100 + $90

= $1,190

Hence, the opportunity cost of playing football for Graham is $1,190.

Answer:

10/27

Step-by-step explanation:

Simplify the following:

(5/6)/(9/4)

Multiply the numerator by the reciprocal of the denominator, (5/6)/(9/4) = 5/6×4/9:

(5×4)/(6×9)

The gcd of 4 and 6 is 2, so (5×4)/(6×9) = (5 (2×2))/((2×3) 9) = 2/2×(5×2)/(3×9) = (5×2)/(3×9):

(5×2)/(3×9)

Answer:

  19 mL

Step-by-step explanation:

You want the volume of a rock with density 45 g/mL and mass of 855 g.

The units of density are mass per volume, so we can find the volume by dividing the mass by the density. The units basically tell you how to work the problem.

  [tex]\dfrac{855\text{ g}}{45\text{ g/mL}}=\dfrac{855}{45}\,\dfrac{\text{g$\cdot$mL}}{\text{g}}=\boxed{19\text{ mL}}[/tex]

Additional comment

Sometimes we like the volumes of things that aren't liquid to be expressed in cubic units. 1 mL = 1 cm³, so the volume could be described as 19 cm³.

Answer:

  41 13/40

Step-by-step explanation:

Generally, you're told to multiply mixed numbers by converting each to an improper fraction:

  5 7/10 = (5·10 +7)/10 = 57/10

  7 4/16 = (7·16 +4)/16 = 116/16

The fractions are multiplied by multiplying their numerators to get the numerator of the result, and multiplying their denominators to get the denominator of the result.

  [tex](5\frac{7}{10})(7\frac{4}{16})=\dfrac{57}{10}\cdot\dfrac{116}{16}=\dfrac{57\cdot116}{10\cdot16}=\dfrac{6612}{160}\\\\=41+\dfrac{52}{160}=\boxed{41\frac{13}{40}}[/tex]

__

You don't have to mess with reducing the fraction of the result if you reduce the fraction 4/16 to 1/4 to begin with. Then the product is (57/10)(29/4).

_____

Alternate solution

You can also treat this as the product of two sums. The distributive property is handy for this.

  (5 + 7/10)(7 + 1/4) = (5)(7) +(5)(1/4) +(7/10)(7) +(7/10)(1/4)

  = 35 +5/4 +49/10 +7/40

  = 35 +1 +1/4 + 4 + 9/10 + 7/40 . . . . take out the integer parts

  = 40 +10/40 +36/40 +7/40 . . . . . . use 40 as a common denominator

  = 40 +53/40 = 41 13/40
