What is the probability for blue or yellow (be sure to simplify)? ​

[tex]\boxed{x^2-1}[/tex] is the ans

First, multiply x times x :

x²

Now multiply x times (-1) :

-1x or -x

Right now we have

x²-x

Now multiply 1 times x :

x

x²-x+x

Now multiply -1 times 1 :

-1

x^2+x-x-1

the x's cancel :

x^2-1

7(1+2x)

Use the distributive property :

7+14x

Is 7+14x equivalent to 6+12x? No.

The expression equivalent to 6+12x is :

6(1+2x) ← divide 6+12x by 6 and put it outside the parentheses

Answer:

Total Area = 1200 in^2

Step-by-step explanation:

There is a triangle and a rectangle.

Arca Triangle: Area = 1/2 * Base* Height

Area = 1/2 * 40 in * 30 in = 600 in^2

Area Rectangle: Area = Length* Width

Area = 30 in * 20 in = 600 in^2

Total Area = Area Rect + Area Tri

Total Area = 600 in^2 + 600 in^2 = 1200 in^2

Answer:

Step-by-step explanation:

Answer:

let x equal the service charge.

let y equal the per hour charge.

for the job that cost 450, the equation is 450 = x + 6y

for the job that cost 330, the equation is 330 = x + 4y

these two equations needs to be solved simultaneously.

subtract the second equation from the firs to get 120 = 2y

solve for y to get y = 60.

in the first equation, replace y with 60 to get 450 = x + 6*60.

simplify to get 450 = x + 360.

subtract 360 from both sides of the equation to get 90 = x.

it appears that the service charge is equal to 90 and the per hour charge is equal to 60.

for the job that cost 450, the equation becomes 450 = 90 + 6*60 = 90 + 360 = 450.

for the job that cost 330, the equation becomes 330 = 90 + 4*60 = 90 + 240 = 330.

the numbers check out.

the service charge is 90.

the per hour charge is 60.

i believe your solution is that the electrician charges a flat fee of 90 plus an hourly fee of 60 for a service call.

Step-by-step explanation:

IT"S APPLE!!!

Answer:

(2.5, 0)

Step-by-step explanation:

The point in which a line crosses the x-axis is also known as the x- intercept. x-intercepts occur at y= 0, so let's substitute y= 0 into the equation and solve for x.

2x +y= 5

When y= 0,

2x +0= 5

2x= 5

Divide both sides by 2:

x= 2.5

Thus, the coordinate is (2.5, 0).

Answer:

C. 30%

Step-by-step explanation:

If you subtract 26.25 from $37.50, you're left with a difference of 11.25.

Given that your question has six possible answers, you can eliminate three of them considering 11.25 is somewhat close to 1/3 of 37.50.

After you've eliminated the first three options, you're left with 30%, 35%, and 40%.

You would get 28.125 by multiplying 11.25 by 2.5 (equal to 40%). So we know that 40% is NOT the solution.

You would get 33.75 by multiplying 11.25 by 3 (equivalent to 33.3 percent). So we know that 35% percent is NOT the solution because a figure less than 35 percent doesn't equal 37.5 percent.

Now that two of the three possible responses have been ruled out, you're left with only one correct answer, 30 percent.

Multiply 37.5 by 0.3 to double-check your work. You'd be left with 11.25, which is the same amount as when you subtracted the dress's price after the discount from the original dress's price.

If the surface area of the stand to be 35 ft². The number of ropes purchase is 45.3125ft and  Percent of stand area is 83%.

Given:

Base area=3ft²

Height=3.2 feet

Surface area=35ft²

a. Number of ropes

Surface area=2×Base area×Base perimeter×Height

Base perimeter(BP):

35=2×3+BP×3.2

35=6+3.2BP

Collect like term

3.2BP=35-6

3.2BP=9

Divide both side by 3.2BP

BP=29/3.2

BP=9.0625ft

Number of ropes=5×9.0625ft

Nimber of ropes=45.3125ft

b. Percent of stand area:

Percent of stand area=(9.0625ft×3.2)÷35ft²

Percent of stand area=29ft²÷35ft²×100

Percent of stand area=82.857ft×100

Percent of stand area=83% (Approximately)

Therefore the number of ropes purchase is 45.3125ft and  Percent of stand area is 83%.

Answer: Sqaure

Step-by-step explanation:

We obtain the figure by either plotting or finding the distances between the points:

[tex]\begin{aligned}&\text { Distance } b / w \quad A B =\sqrt{(1-7)^{2}+(3-(-3))^{2}}\\&=\sqrt{6^{2}+6^{2}}\\&A B=\sqrt{72} \text { units }\end{aligned}[/tex]

[tex]\text { Distance } b / w \quad BC =\sqrt{(7-1)^{2}+(-3-(-9))^{2}} \\BC=\sqrt{72} \text { units }[/tex]

[tex]\begin{aligned}\text { Distance } b / w \ C D &=\sqrt{(1-(-5))^{2}+(-9-(-3))^{2}} \\C D=\sqrt{72} \text { units }\end{aligned}[/tex]

[tex]$$ Distance $b/w \ A D=\sqrt{(1-(-5))^{2}+(3(-3))^{2}}$A D=\sqrt{72} \text { units }[/tex]

Since all the distances of the four sides are equal, we have to check if the shape is either a rhombus or a square by the measuring the length of the diagonals

[tex]\begin{aligned}A C &=\sqrt{(1-1)^{2}+(3-(-9))^{2}} \\&=\sqrt{12^{2}} \\A C &=12 \text { units } \\B D &=\sqrt{(7-(-5))^{2}+(-3-(-3))^{2}} \\&=\sqrt{12^{2}} \\A C &=12 \text { units }\end{aligned}[/tex]

The diagonals are also equal; therefore, the figure is a square
