a. the lines intersect at one point
b. the lines are parallel
c. the lines are the same
d. the lines cannot he graphed

Answer:

$216

Step-by-step explanation

We know that we are paying 80% of the price of the airpods (20% off) so we can multiply the full price by 0.8.

250 * 0.8

This will give us 200.

Now, we need to add the sales tax which is 8%.

Simply multiply the 200 by 1.08 since we are paying the 200$ plus an extra 8% of the cost.

200 * 1.08 = $216

Step-by-step explanation:

The value of the length of the newspaper is 21.52 inches and the width is 22.74 inches.

The rectangle is a geometrical figure in which opposite sides are equal.

The angle between any two consecutive sides will be 90 degrees.

Area of rectangle = length × width.

Perimeter of rectangle = 2( length + width).

Lets say,

Length of newspaper = l

Width of newspaper = w

Area of newspaper ( rectangle ) = l × w

Now,

Length is about 1.22 times its width.

So,

l = 1.22w

By substituting

1.22w × w = 630.92

1.22w² = 630.92

w² = 517.147

w = 22.74 inches

So,

l = 1.22 × 22.74

l = 21.52 inches

Hence "The value of the length of the newspaper is 21.52 inches and the width is 22.74 inches".

Answer:

Step-by-step explanation:

We can use a proportion to solve this.

Let x = how long the room is on the map

So, x/32 = 0.5/4

Cross multiply

4x = 16

Divide by 4

x = 4

Check

4/32 = 0.5/4

4 x 4 = 32 x 0.5

16 = 16

red: 13/33

yellow: 12/33

blue: 8/33

Step-by-step explanation:

Add together all of the values to find the total amount of sections (13+12+8=33) --> this will be your denominator

From there, each time you make the numerator the number of that color, which gives you:

red: 13/33

yellow: 12/33

blue: 8/33

Answer:

The probability of landing on red is 13/33, the probability of landing on yellow is 12/33, and the probability of landing on blue is 8/33.

Step-by-step explanation:

Everything is just a fraction, so just add all the numbers for your denominator, and put the other number for red yellow or blue as the numerator then simplify the fraction

Answer:

y = 6

Step-by-step explanation:

You solve by using the pythagorean theorem, which is:

[tex]a^{2} +b^{2} =c^{2}[/tex]

Where a and b are legs of the triangle, and c is the hypotenuse, or y in this case. So let's rearrange this equation for c:

[tex]c=\sqrt{a^{2} +b^{2} }[/tex]

Now, we can substitute in the known values and solve:

[tex]c=\sqrt{3.6^{2} +4.8^{2} } = \sqrt{36} = 6[/tex]

Therefore, the value of y is 6

Step-by-step explanation:

We find the stationary point of (20 + 2x)(1200 - 60x),

where x is the unit rate of increase/decrease.

d/dx [(20 + 2x)(1200 - 60x)]

= d/dx (-120x² + 1200x + 24000)

= -240x + 1200.

When d/dx [(20 + 2x)(1200 - 60x)] = 0,

We have -240x + 1200 = 0. => x = 5.

Price per shirt that maximise revenue

= $20 + $2x = $20 + $2(5) = $30.

Maximum revenue

= (20 + 2(5))(1200 - 60(5))

= $30 * 900 = $27,000.

Since, a rectangle with a diagonal of length x is twice as long as it is wide, the area of the rectangle is (B) 2x²/5

Given that we have a rectangle with a diagonal of length x is twice as long as it is wide.

Let

Given that the length of diagonal, x is twice as long as it is wide, we have that

L = 2W

Also, since it is rectangle, we have that

D² = L² + W²

D² = (2W)² + W²

D² = 4W² + W²

x² = 5W²

W² = x²/5

W = x/√5

W = x√5/5

Since the length of the rectangle, L = 2W, we have that

L = 2W

= 2x√5/5

The area of the rectangle is given by A = LW where

So, A = LW

= 2x√5/5 × x√5/5

= 2x² × 5/25

= 2x²/5

So, the area of the rectangle is (B) 2x²/5
