The length of a rectangle is 3 inches more than its width. if the perimeter is 42 inches, find the dimensions of the rectangle

Answers

Answer 1

Answer:

length = 12

width = 9

Step-by-step explanation:

Let w= width of rectangle

length = w + 3

2w + 2(w + 3) = 42

2w + 2w + 6 = 42

4w = 36

w = 9 ( width of rectangle)

width = 9 inches

length = 9 + 3 = 12 inches

What is an equation of the line that passes through the point (-6,-1) and is perpendicular to the line 6x-y=7

Answers

Answer:

y=-1/6x-2

Step-by-step explanation:

Lets find the slope of the given line

6x-7=y,m=6

The slope of the perpendicular line would be=-1/6

Using the point-slope form y-y1=m(x-x1)

y--1=-1/6(x--6)

y+1=-1/6(x+6)

6y+6=-x-6

6y=-x-6-6

6y=-x-12

y=-1/6x-2

The speed (v) of a gear varies inversely as the number of teeth (t). If a gear that has 48 teeth makes 20 revolutions per minute, how many revolutions per minute will a gear that has 30 teeth make?

I'll give Brainliest! Please no links

Answers

Answer:

32 revolutions per minute(rpm)

Step-by-step explanation:

v inversely proportional to t

so if v increases t will decrease and vice versa

inverse equation is xy=k

xy=k

48×20= 960 (revolutions)

then you'll take k(960) and divide it by number of teeth

so..

960/30 = 32 revolutions per minute

The equation of line will be;

⇒ y = - 3/5x + 3

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

James draws a line that has an x-intercept of "-5" and y-intercept of 3 on a piece of graph paper.

Now,

Since, James draws a line that has an x-intercept of "-5" and y-intercept of 3 on a piece of graph paper.

Hence, The slope of the line = - 3/5

And, The y - intercept = 3

Thus, The equation of line will be;

⇒ y = - 3/5x + 3

A girl starts from Point A and walks to 285m to B on a bearing of 078°. She then walks due south to a point C which is 307m from A. What is the bearing of A from C and what is IBCI​

Answers

Answer:

bearing of A from C is - 65.24°

the distance |BC| is 187.84 m

Step-by-step explanation:

given data

girl walks AB = 285 m (side c)

bearing angle B = 78°

girl walks AC = 307 m (side a)

solution

we use here the Cosine Law for getting side b that is

ac² = ab² + bc² - 2 × ab × cos(B)     ...............1

307² = 285² + x²  - 2 × 285 cos(78)

x = 187.84 m

and

now we get here angle θ , the bearing from A to C get by law of sines

sin (θ) =

sin (θ) =  0.5985  

θ = 36.76°

and as we get here angle BAC that is

angle BCA = 180 - ( 36.76° + 78° )

angle BCA = 65.24°

and here  negative bearing of A from C so - 65.24°
