A) 45 is 9 times as many as 5
B) 72 is 8 times as many as 9
C) 44 is 4 times greater than 11
D) 63 is 7 times as many as 7
E) 21 is 3 times greater than 9

Answer: 3 1/4 inches

Step-by-step explanation:

9 3/4 - 6 1/2

I turned 6 1/2 into an easier fraction so it can be easier to subtract. Now the expression is:

9 3/4 - 6 2/4

6 2/4 is equivalent to 6 1/2

I then got 3 1/4

Answer:

Step-by-step explanation:

Given the expression [tex]\left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right] \cdot \left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right]^{-1}[/tex]

According to indices:

[tex]a^{-1} = \frac{1}{a}[/tex]

Applying this to the question:

[tex]\left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right]^{-1} = \frac{1}\left\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right}[/tex]

Hence:

[tex]\left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right] \cdot \left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right]^{-1} = \frac{\left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right]}{\left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right]} \\\\\left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right] \cdot \left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right]^{-1} = 1[/tex]

Hence the right answer is 1

Answer:

the three vertices are (1, 1), (2, 0), (-1, -3).

The vertices of the triangles are the coordinates of the point of

intersection of the graph of the equation of the three lines.

Correct response:

The coordinates of the three vertices of the triangles are;

E. [tex]\underline{(2, 0), \ (1, -1), \ and \ (-1, -3)}[/tex]

The equation of the given lines are;

y = -x + 2, y = 2·x - 1, y = x - 2

The point of the intersection of the two lines, gives the vertices, and are

the solution of the two linear equations of the lines.

At the points where the lines intersect, we have;

-x + 2 = 2·x - 1

Which gives;

3·x = 3

x = 1

y = -1 + 2 = -1

A vertex is at the point (1, -1)

The coordinate of the second vertex is given as follows;

2·x - 1 = x - 2

2·x - x = -2 + 1 = -1

x = -1

y = -1 - 2 = -3

The second vertex is; (-1, -3)

The coordinates of the third vertex is given as follows;

-x + 2 = x - 2

2·x = 4

x = 2

y = 2 - 2 = 0

Which gives the point; (2, 0)

Answer: g

Step-by-step explanation:

4348x.065=282.62

282.62x5=1413.1

282.62x3=847.86

1413.1-847.86=565.24

Compared to a 3-year loan he has to pay G. $565.24 more for a 5-year loan.

We know simple interest (SI) is given by SI = (p×r×t)/100, where

p = principle, r = rate in percentage, and t = time in years.

Given, Mr. Fitch needs to get a loan to replace the air-conditioning system.

He can apply for a 5- year loan or a 3-year loan. Both loans involve simple interest with an annual interest rate of 6.5%.

Here, p = $4,348.00, r = 6.5%, t₃ = 3 and t₅ = 5.

For, t₃.

SI₃ = (4348×6.5×3)/100.

SI₃ = $847.86.

For, t₅.

SI₅ = (4348×6.5×5)/100.

SI₅ = $1,413.1.

So, the amount of interest he will have to pay more is (SI₅ - SI₃).

=  $(1,413.1 - 847.86).

= $565.24.

Answer:

200 miles

Step-by-step explanation:

Let's say that our variable is x, where x equals the amount of miles

Company A: a(x)=0.6x+130

Company B: b(x)=0.9x+70

For the first equation, you are charged 130 dollars, in addition to the 0.60 cents that you are charged per mile.

For the second equation, you are charged 70 dollars, in addition to the 0.90 cents that you are charged per mile.

You want to find how many miles it takes to make the two equations equal:

0.6x+130 = 0.9x+70 (Set them equal to each other because you are trying to find when the miles are equal and the cost is equal)

130=0.3x+70 (Subtract 0.6x from both sides)

60=0.3x (Subtract 70 from both sides)

x=200 (Divide both sides by 0.3 to find x)

Remember that x is the amount of miles, so, Company A and B would charge the same if you drove 200 miles.

Answer:I believe it’s 200 miles

Step-by-step explanation: let x represent the mileage you are trying to find and set the two equations equal to one another to find the mileage and which the rental cost would be the same.

130 + 0.60x = 70 + 0.90x

130-70 = 0.90x - 0.60x

60 = 0.30x

X= 60/0.03

X= 200 miles

Answer:

x = 4, (-2/3)

Step-by-step explanation:

3(x^2) – 10x = 8

3(x^2) – 10x - 8 = 0

(3x + 2)(x - 4) = 0

(3x + 2) = 0

3x = -2

x = (-2/3)

(x - 4) = 0

x = 4

Answer:

x = -2/3, 4

Step-by-step explanation:

move all terms to one side

3x^2 - 10x - 8 = 0

split the terms in 3x^2-10x-8 into two terms

3x^2+2x-12x-8=0

factor out common terms in first to and last to

x(3+2)-4(3x+2) =0

factor out common term 3x+2

(3x+2) (x-4)=0

solve for x

x=-2/3,4

Answer:

Step-by-step explanation:

Total Number of Marbles in the bag = 15

The probability of randomly selecting a green marble is 1/3

The probability of randomly selecting a green marble, replacing it, and then randomly selecting a red marble = 1/15

The probability of randomly selecting a green marble, replacing it, and then randomly selecting a red marble is calculated as

The probability of randomly selecting a green marble × The probability of randomly selecting a red marble

Hence:

1/15 = 1/3 × R

1/15 = R/3

Cross Multiply

R × 15 = 1 × 3

R= 3/15

R= 1/5

Hence, the probability of randomly selecting a red marble is 1/5
