The length of a rectangle is five times its width.
If the area of the rectangle is 405cm^2, find perimeter

Answers

Answer 1

Answer:

108

Step-by-step explanation:

Let's say the width is x

Of the length is 5 times the width, then the length is 5x

Area = length * width

405 = x * 5x

405 = 5x^2

405/5 = 5x^2/5

81 = x^2

Take the square root of both sides

2/[81 = 2/[x^2

9 = x = width

9 × 5 = 45 = length

Perimeter = 2 × length + 2 × width

2 × 45 + 2 × 9

90 + 18 = 108

First, find the area of the table...

d = 4 ft  ---> r = 2 ft

Area = 3.14 * (2 ft)² = 12.56 ft²

Find how many pads will cover the entire table. Since each pad is 1 ft²...

# of pads = 12.56 ft² / 1 ft² = 12.56

Find the total cost for all pads...

Total cost = 12.56 * $0.75 = $9.42

43 A rescue boat on the ocean surface detects a sunken ship on the ocean floor. The sunken
ship makes an angle of 55° with the surface.
The distance between the rescue boat and
the sunken ship is 250 m.

Answers

Using the slope concept, it is found that the ship is sunken at a depth of 357 meters.

What is a slope?

The slope is given by the vertical change divided by the horizontal change, and it's also the tangent of the angle of depression.

In this problem:

The vertical change is the depth d.The horizontal change is of 250 m.The angle is of 55º.

Hence, applying the slope:

[tex]\tan{55^\circ} = \frac{d}{250}[/tex]

[tex]d = 250\tan{55^\circ}[/tex]

[tex]d = 357[/tex]

The ship is sunken at a depth of 357 meters.

Answers

Answer:

angle 1: 30

angle 2: 41

angle 3: 96

Step-by-step explanation:

So the angles' sum in one triangle is 180 degrees so you know two of the first triangle's angles so you sum them up and you get: 150 so now you subtract that from 180 and get 30.

Now you can see that if you want to get angle 2 you need to get angle 3 first. so you can see that the 84 degrees is on the same line as angle 3 so, we also know that a line is 180 degrees. so 180-84=96.

Now to get angle 2 we just simply sum up 43 and 96 which is 139, then we subtract that from 180, then we get 41.

Answers

Answer:

Your answer will be y=x2−12x+32

Step-by-step explanation:

Step 1 : x = 4 and  x = 8 are the two real distinct solutions for the quadratic equation, which means that  x − 4  and  x − 8 are the factors of the quadratic equation. ( x − 4 ) ( x − 8 ) = 0

Step 2: Expand  ( x − 4 ) ( x − 8 ) using the FOIL Method. x ⋅ x + x ⋅ − 8 − 4 x − 4 ⋅ − 8 = 0

Which would give you x2 − 12 x + 32 = 0

Step 3: The standard quadratic equation using the given set of solutions

{ 4  , 8 } is y = x 2 − 12 x + 32 .

This is you answer should be  

y = x 2 − 12 x + 32

The perimeter of the rectangle below is 102 ft. What is the value of X
one side is (2+x) ft
the other is 3 ft​

Answers

Answer:

X=46 ft.

Step-by-step explanation:

Write an equation to solve the problem.

Since one side is 3 ft, don’t forget that there is another side of the rectangle that is also 3 ft. We can add this part to the equation as 2(3).

Now, let’s see the other side. It’s (2+x) ft. As mentioned before, there are another side, so, you guessed it: 2(2+x).

We have our equation:

2(3)+2(2+x) = 102 ft.

Simplify first:

6+4+2x = 102 ft.

10+2x=102 ft.

2x=92 ft.

x=46 ft.

What is mean by Angle?

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Given that;

In the diagram, quadrilateral HIJK is inscribed in circle L.

Now, We know that;

sum of opposite angle are 180 degree.

Hence, We get;

∠H + ∠J = 180

67 + (y - 75) = 180

y - 8 = 180

y = 180 + 8

y = 188

And, We get;

∠I + ∠K = 180°

96 + (x + 83) = 180

x + 179 = 180

x = 180 - 179

x = 1

Thus, The value of variables x and y are,

x = 1 and y = 188
