Answer:

The correct answer is = p = 15 and q = 6.

Step-by-step explanation:

Given:

Perimeter of rectangle = 42 cm

p - q = 9 cm

length = p

width = q

we know:

Perimeter of rectangle= 2(l+w)

solution:

42 = 2(P+q)

21= p+q

Difference of p and q = 9 cm.

Then, P+q=21 .... 1

P-q=9 ....2

Adding both 1 and 2

2P = 30

P= 15cm and

q = 15-9

= 6cm

Step-by-step explanation:

"cos" by itself is meaningless. It needs an argument.

cos(x°) = 5/36

x° = arccos(5/36) ≅ 82.2°

Step-by-step explanation:

[tex]\frac{3}{x+3}-\frac{4}{x-3}=\frac{3*(x-3)}{(x+3)(x-3)}-\frac{4(x+3)}{(x-3)(x+3)}\\\\=\frac{3*x-3*3}{(x+3)(x-3)}-\frac{4*x+4*3}{(x+3)(x-3)}\\\\=\frac{3x-9}{x^{2}-3^{2}}-\frac{4x+12}{x^{2}-3^{2}}\\\\=\frac{3x - 9 -(4x + 12)}{x^{2}-3^{2}}\\\\=\frac{3x-9-4x-12}{x^{2}-9}\\\\=\frac{-x-21}{x^{2}-9}\\\\[/tex]

[tex]\frac{3}{x+3}-\frac{4}{x-3}=\frac{5x}{x^{2}-9}\\\\\frac{-x-21}{x^{2}-9}=\frac{5x}{x^{2}-9}\\\\-x-21=\frac{5x}{(x^{2}-9)}*(x^{2}-9)\\[/tex]

-x - 21 = 5x

Add 'x' to both sides

-x -21 +x = 5x + x

        -21 = 6x

6x = -21

x = -21/6

   = -7/2

x = -3.5

Answer:

Question 4: x = 106

Question 5: x = 118

Step-by-step explanation:

Question 4: The exterior angles of a triangle are going to add up to 360.

128 + 126 = 254

360 - 254 = 106

x = 106

Question 5: The exterior angles of a polygon add up to 360 (a quadrilateral is a polygon).

A right-angle = 90

90 + 34 = 124

360 - 124 = 236

236 / 2 = 118

x = 118

I hope this helps! :)

Answer:

75%

Step-by-step explanation:

You need to find the total number of votes first. Just add 13 and 39 which would equal 52.

Then divide the number of people in favour by the total number of voters and multiply by a 100 to find the percentage.

39 + 13 = 52

39/52 = 0.75

0.75 x 100 = 75.0

75%

Answer:

C. geometric; 125

Step-by-step explanation:

first term(a) = 0.2

common ratio (r) = 1 / 0.2 = 5

now

Answer:

y=-3x+6

Step-by-step explanation:

x-3y=5

y=1/3x-5/3

slope of perpendicular line is -3 (opposite reciprocals)

y=mx+b

x=0 and y=6

6=3x+b

6=3(0)+b

6=b

y=-3x+6

Step-by-step explanation:

The Median is $34.99.

It is required to find the median.

The median is the middle value in a set of data. First, organize and order the data from smallest to largest. The median is the value separating the higher half from the lower half of a data sample.

Given:

The data below :

$19.99, $8.99, $35.99, $49.99, $49.99, $39.99, $99.99, $79.99, $35.99, $19.99, $49.99, $29.99, $49.99, $59.99, $35.99, $49.99, $19.99, $8.99, $29.99, $35.99

The middle numbers are $19.99 and $49.99, add them both and divide by 2 we have,

Median

=$19.99 +$49.99/2

= $34.99.

Therefore, the Median is $34.99.

Step-by-step explanation:

Answer:

-3x - 6 = -9    (The third answer)

Step-by-step explanation:

When solving for x, you have to undo each operation. When solving -3x - 6 = -9, you have to undo the -6 first. To do this, add 6 to both sides. Then, you must undo the -3x. To do this, divide by -3 from both sides.

Answer:

D. 25% decrease

Step-by-step explanation:

Since it's clear that they read less books to find how much it decreased we multiply 100 with 15 then divide it by 20

100 × 15 ÷ 20 = 75 this result shows a 25% decrease.

Answer:

D'(1,5)

Step-by-step explanation:

If you rotate a point 180 counter-clockwise around the origin, then it makes the x and y coordinates negative. In this case, it would make the coordinates positive because both coordinates are already negative. The answer would be D'(1,5).

Step-by-step explanation:

La temperatura en Moscú es de 13 grados bajo cero. Entonces, la temperatura es de -13 grados.

La temperatura en Buenos Aires es de 25 grados bajo cero. Entonces, la temperatura es de 25 grados.

La diferencia de temperatura entre las dos ciudades es

[tex]25-(-13)=38\ \text{grados}[/tex]

La diferencia de temperatura entre las dos ciudades en un momento dado es  [tex]38\ \text{grados}[/tex].

Answer:

(x + 8) + (x + 8) + (x + 3) + (x + 3)

and

4x + 22

Two equivalent expressions to represent the perimeter of the boat dock are P = 2[(X + 8) +(X + 3)] or P = 4X + 22.

"A perimeter is a measurement of the outside of a shape. In order to find a perimeter, we have to find the sum of all the sides of the shape."

Given

Length of the dock = (X + 8) feet

Width of the dock = (x + 3) feet

A rectangle have length and width.

So the perimeter of the rectangle is 2(length + width)

Formula to find the perimeter of shape

Perimeter of the shape = Sum of all the sides of the shape

P = (X + 8) +(X + 3) + (X + 8) +(X + 3)

⇒ P = 2[X + 8 +X + 3]

⇒ P = 2[2X + 11]

⇒ P = 4X + 22

Hence, two equivalent expressions to represent the perimeter of the boat dock are P = (X + 8) +(X + 3) + (X + 8) +(X + 3) or P = 4X + 22.
