Explanation:

This is a 45-45-90 right triangle. Any triangle of this form is isosceles, where the two legs are the same length. In this case, m and n are those two legs. So m = n.

We can then apply the Pythagorean theorem to say

a^2 + b^2 = c^2

m^2 + n^2 = (9*sqrt(2))^2

m^2 + m^2 = 9^2*(sqrt(2))^2

2m^2 = 81*2

m^2 = (81*2)/2

m^2 = 81

m = sqrt(81)

m = 9

As a shortcut, the hypotenuse of a 45-45-90 triangle is equal to sqrt(2) times the length of either leg. If m is the length of the leg, then m*sqrt(2) is the length of the hypotenuse. So in a sense, we take this thought process backwards to go from a hypotenuse 9*sqrt(2) to a leg length of 9.

Answer:

It is more likely she draws 2 red cards

Step-by-step explanation:

Given that:

Number of red d cards in deck = 26

Number of face cards = 4 * 3 = 12 face cards

If two cards are drawn with replacement ;

Probability = (required outcome / Total possible outcomes)

P(1st card red) = 26 /52) = 1/2

P(2nd card red) = 26 /52 = 1/2

P(1st card red) * P(2nd card red)

1/2 * 1/2 = 1/4 = 0.25

P(1st card face card) = 12/52 = 3/13

P(2nd card, face card) = 12/52 = 3/13

P(1st card face card) * P(2nd card face card)

3/13 * 3 /13 = 9/169 = 0.053

0.25 > 0.053

It is more likely she draws 2 red cards

Answer:

C. The relationship between the quantities is: add 25.

Step-by-step explanation:

1x = 25y,

2x = 25 + 25 = 50y

3x = 50 + 25 = 75y

4x = 75 + 25 = 100y

Note:

As you can see, every time the number goes up on the chart, it goes up by 25 and you can find that out by just simply adding 25 to the first number and seeing if it matches up with the next, (which I did above).

Answer:

x = -0.4

Step-by-step explanation:

Given:

-9x + 0.4 = 4

To move all constant to the right side of the equation, perform subtraction operation

That is, subtract 0.4 from both sides of the equation

-9x + 0.4 - 0.4 = 4 - 0.4

-9x = 4 - 0.4

-9x = 3.6

Perform division operation to isolate the variable

That is, divide both sides by -9

-9x / -9 = 3.6 / -9

x = -0.4

Answer:

1 Subtract 0.4

2 Divide by -9 on both sides

3 -0.4

Answer:

n = - [tex]\frac{4}{3}[/tex]

Step-by-step explanation:

Given

- 5(n - 1) = 7(n + 3) ← distribute parenthesis on both sides

- 5n + 5 = 7n + 21 ( subtract 7n from both sides )

- 12n + 5 = 21 ( subtract 5 from both sides )

- 12n = 16 ( divide both sides by - 12 )

n = [tex]\frac{16}{-12}[/tex] = - [tex]\frac{4}{3}[/tex]

Answer:

Step-by-step explanation:

To solve this you have to use the distributive property.

So first you would distribute the -5 to n and -1.

So the new equation will be -5n + 1 = 7 (n + 3)

Next, distribute the 7 to n and 3.

The new equation will be -5n + 1 = 7n + 21

Next you simplify by adding 5n to both sides which will give you 1 = 12n + 21

Then you subtract 21 from both sides and get -20 = 12n

So then you divide both sides by 12 to get n by itself and you are left with  -5/3 = n

Answer:  The question is The Gardener charged $0.50 per plant and a flat payment of $75. Which function represents this scenario?

The answer is 0.50x-75

The total cost will be the product of the gardener charged and the number of plants. The total cost is $ 37.5

It is also known as the product. If the object n is given to m times then we just simply multiply them.

The gardener charged $ 0.50 per plant and $75 to plant all of them.

Let X be the gardener charged and Y be the number of plants.

The total cost will be the product of the gardener charged and the number of plants. That can be written as

Total cost = X × Y

Total cost = 0.50 × 75

Total cost = $ 37.5

Answer:

1. y = 4x - 4

2. y = x + 2

3. y = -2x - 4

4. y = -x + 2

Step-by-step explanation:

Slope-intercept form is y = mx+b. As we know, m is the slope and b is the y-intercept. We need to find the slope and y-intercept and put them in the equation. Slope is rise over run, so we just count up then over until we get to an intersection. For the y-intercept, we look where the line crosses the y-axis.

Answer:

$843.67

Step-by-step explanation:

1. Calculate the discount that was taken off from the original price.

$896 x 12% = $107.52

2. Subtract the discount taken off from the original price. This gives you the total paid AFTER the discount was taken.

$896-$107.52= $788.48

3. Calculate the tax amount by multiplying the discount price by the tax rate.

$788.48 x 7% = $55.19

4. Add the tax amount back to the discount price.

$788.48 + $55.19 = $843.67
