What is a rectangle?

It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In rectangle opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at mid-point.

Given

A rectangle has a width of 12.5 m and a length of 105 m.

We know the perimeter of the rectangle is given by

Perimeter = 2 (Lenght + Width)

Let x be the length and y be the width. Then

Perimeter = 2 (x + y)

If the dimensions are multiplied by 2. Then the effect on the perimeter will be

Perimeter = 2 (2x + 2y)

Perimeter = 2 [2 (x + y)]

The perimeter is increased by a factor of 2.

Thus, option A is correct.

A
x+22=180

B
x+22=90

C
22−x=180

D
22−x=90

Answers

Answer:

i think the answer is b

because,

if x+22=90

x=90-22=68

we know that the sum of the three angles of a triangle is 180

so, that means

90+22+68 should be 180

and it is 180, so the answer must be b

Find the slope of the line that passes through G(−3, 2) and H(7, 2).
PLEASE I DONT HAVE TIME I BEG U

Answers

Slope = (y2-y1) / (x2-x1)
G(-3,2) = (x1,y1)
H(7,2) = (x2,y2)
Substitute these values to find the slope.
Slope = (2-2)/(7-(-3)) = 0/10 = 0

The solution is,  the slope of the line that passes through G(−3, 2) and

H(7, 2) is 0.

What is slope?

In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

here, we have,

given that,

G(−3, 2) and H(7, 2).

now, we have to find, the slope of the line that passes through G(−3, 2) and H(7, 2).

now, we know that,

Slope = (y2-y1) / (x2-x1)

here,

G(-3,2) = (x1,y1)

H(7,2) = (x2,y2)

Substitute these values to find the slope.

Slope = (2-2)/(7-(-3))

          = 0/10

          = 0

Hence, The solution is,  the slope of the line that passes through G(−3, 2) and  H(7, 2) is 0.

Answer:

Given :

The length of a rectangle is 4 cm more than its width

The area of the rectangle is 96 cm²

To Find :

Width of the rectangle.

Solution :

Let the length of the rectangle be x cm.

Let the breadth of the rectangle be y cm.

Case 1:

➣  _____(1)

Case 2 :

We have the formula for area of the rectangle as follows :

Where,

l = length → x cm

b = breadth → y cm.

Substitute, x = 96/y in equation 1,

Divide by minus sign,

As per assumption, y = breadth of the rectangle.

What is the equation of the line that passes through the point (−8,−7) and has a slope of 1?

Answers

Answer:

y = x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = 1 , then

y = x + c ← is the partial equation

To find c substitute (- 8, - 7 ) into the partial equation

- 7 = - 8 + c ⇒ c = - 7 + 8 = 1

y = x + 1 ← equation of line

A vessel sails 41 miles S 45 E. How far south has it sailed?

119 miles
61 miles
29 miles

Answers

Answer:

[C] 29 Miles

Step-by-step explanation:

Given that the vessel sails 41 miles S 45° E.

We need to determine the how far south the vessel has sailed.

Let us use the Pythagorean theorem to find the distance of the vessel has sailed.

Thus, we have,

[tex]Cos 0= \frac{adj}{hyp}[/tex]

Substituting [tex]0 = 45[/tex]° , [tex]adj = x[/tex], and [tex]hyp = 41[/tex]

Hence, we get,

[tex]cos[/tex] [tex]45 = \frac{x}{41}[/tex]

Simplifying, we have,

[tex]0.71 = \frac{x}{41}[/tex]

Multiplying both sides by 41, we have,

[tex]29.11 = x[/tex]

Rounding off to the nearest integer, we have,

[tex]29 = x[/tex]

Thus, the vessel has sailed 29 miles South.

Therefore, Option C is the correct answer.
