If x = –12 and y = 16, evaluate x + y – 5x.

Answer:

1/2

Step-by-step explanation:

12 is the rise 24 is the run

12/24 simplified is 1/2

The required slope of the given ramp is given by 1/2. Option C is correct.

Given that,
A motocross ramp is 12 feet tall and 24 feet long. What is the slope of the ramp as a fraction in the lowest terms is to be determined.

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,
The slope of the ramp is evaluated as,
= vertical height / horizontal distance,
= 12 / 24
= 1 / 2

Thus, the required slope of the given ramp is given by 1/2. Option C is correct.

Answer:

∠ABC = 72°

Step-by-step explanation:

When we look at the triangle carefully, we can see a bar on AC and AB. Those bars define that AC and AB are equivalent. This also means that the triangle is isosceles. Since this triangle is isosceles, the base angles of the triangle are equivalent.

⇒ AB = AC

We also know that the sum of its interior angles must be 180°.

⇒ ∠A + ∠B + ∠C = 180

Let's substitute their angle measures.

⇒ 3x + 6x + 6x = 180                                         [∠BAC = 3x; ∠ABC = ∠ACB = 6x]

Now, let's solve for x.

⇒ 3x + 6x + 6x = 180

⇒ 15x = 180

⇒ 15x/15 = 180/15

⇒ x = 12

Now, substitute the value of x into "6x" to find ∠ABC.

∠ABC = 6x

⇒ ∠ABC = 6(12)

⇒ ∠ABC = 72°

Answer: Choice B

Two imaginary solutions

=======================================================

Explanation:

The given equation is

4x^2 - 3x + 1 = 0

Compare this to the general quadratic

ax^2 + bx + c = 0

to find that a = 4, b = -3, c = 1.

Plug those values into the discriminant formula below.

d = b^2 - 4ac

d = (-3)^2 - 4*4*1

d = 9 - 16

d = -7

Then recall that...

We see that d = -7 fits with the third option highlighted above.

Answer:$1,302.56

Step-by-step explanation:

First you must find the amount she made from working her hours.

$12.75 x 45(hours)=$573.75

Next you must find how much she made from her commission on sales.

$12,675 x 0.0575(5.75% converted to a decimal)=728.8125.

Round 728.8125 to the nearest hundredth to get $728.81.

Add these two numbers together.

$728.81+$573.75=$1,302.56

Answer:

$1,302.56

Step-by-step explanation:

You must first determine how much she earned throughout her working hours.

$12.75 multiplied by 45 hours equals $573.75.

The next step is to determine how much she earned from her sales commission.

728.8125 = $12,675 x 0.0575(5.75 percent converted to a decimal).

To get $728.81, round 728.8125 to the nearest hundredth.

These two integers should be added together.

$728.81+$573.75=$1,302.56

Answer:

the desired equation is y = x + 4.

Step-by-step explanation:

Slope is defined as m = rise over run.  Run is the change (usually an increase) in x, and rise an increase or decrease in y.

We see, in the table, that if x increases from 1 to 6 (a 'run' of 5), y increases from 5 to 10 (a 'rise' of 5).  Thus, it's immediately apparent that the slope is m = rise / run = 5 / 5, or just 1.

Using the slope-intercept form of the equation of a straight line, y = mx + b, and the point (1, 5), we calculate b:

5 = 1(1) + b, or b = 4.

Therefore the desired equation is y = x + 4.

Answer:

-47

Step-by-step explanation:

We will see that the change in momentum is P' - P = -17.6 kg*m/s, and the percentage of kinetic energy lost is 30.56%.

The momentum is given by the product between the mass and the speed.

So the original momentum is:

P = 0.32kg*30m/s = 9.6 kg*m/s

After the bounce, the new velocity is -25m/s, then the new momentum is:

P' = 0.32kg*-25 m/s = -8 kg*m/s

The change in momentum is:

P' - P = -8 kg*m/s - 9.6 kg*m/s = -17.6 kg*m/s

The kinetic energy is:

KE = (1/2)*M*v^2

The initial kinetic energy is:

KE = (1/2)*0.32kg*(30 m/s)^2 = 144 J

The final kinetic energy is:

KE =  (1/2)*0.32kg*(-25 m/s)^2 = 100 J

The percentage lost is:

P = 100%*(144 J - 100J)/(144 J) = 30.56%

Answer:

b = -2.7

Step-by-step explanation:

Isolate the variable, b

-5 = b - 2.3

add 2.3 to both sides (to isolate variable b)

-5 + 2.3 = b - 2.3 + 2.3

-2.7 = b + 0

-2.7 = b

Check work:

-5 = -2.7 - 2.3

[tex]x[/tex] intercept is at (6, 0).

[tex]y[/tex] intercept is at (0, 2).

Step-by-step explanation:

Given the equation of graph:

[tex]3x+9y=18[/tex]

To find:

[tex]x[/tex] and [tex]y[/tex] intercepts of the graph and then plotting the graph.

Solution:

[tex]x[/tex] intercept is the point on graph where the value of [tex]y[/tex] coordinate is zero.

[tex]y[/tex] intercept is the point on graph where the value of [tex]x[/tex] coordinate is zero.

Putting [tex]y=0[/tex] :

[tex]3x=18\\\Rightarrow x = 6[/tex]

So, [tex]x[/tex] intercept is at (6, 0).

Putting [tex]x=0[/tex] :

[tex]9y=18\\\Rightarrow y = 2[/tex]

So, [tex]y[/tex] intercept is at (0, 2).

Plotting the points of [tex]x[/tex] and [tex]y[/tex] intercepts on the graph and joining them to form the graph of given equation.

The missing values for the given two-way table are shown in the image attached below (see attachment).

A two-way table can be described as table that shows the frequencies of two categorical variables in rows and columns respectively.

To find the missing values in the two-way table that is given, simply subtract a known value from the corresponding given total of a row or column.

Thus:

First row total for print and electronics = 33 + 24 = 57

Second row for electronics = 48 - 24 = 24

Second row total for print and electronics = 32 + 24 = 56

Column total for print = 33 + 32 = 65

Third column for grand total = 57 + 56 = 113

Therefore, the missing values for the given two-way table are shown in the image attached below (see attachment).

Answer: Area = 108 in. or 3/4 ft.

Step-by-step explanation: The formula for the area of a rectangle is l•w (length times width).

To get the area, you need to convert the units of measurement to one or the other (either inches or feet) because you cannot multiply them unless they are the same.

To get the area in inches, you convert 3 ft. to inches which is 36 inches, and then multiply it by 3 inches. You will get that the area = 108 inches.

To get the area in feet, you convert 3 inches to feet which is 1/4 (or 0.25) feet and then multiply it by 3 feet which gives you area = 3/4 ft. (or 0.75 ft.). Hope this helps.

Step-by-step explanation:

 *   *    *

let the middle digit is a letter.

as first and second letters are same so consider them as one letter.

It can be filled in 26 ways.

third place is filled in 10 ways (0,1,2,3,4,5,6,7,8,9)

total number of ways=26×10=260 ways

again consider second place is a digit.

so consider second and third place as one digit.

it can be filled in ways=10

first place can be filled in ways=26

Hence number of ways=26×10=260

so total number of ways=260+260=520
