A steep mountain is inclined 74 degree to the horizontal and rises 3400 ft above the surrounding plain. A cable car is to be installed from a point 970 ft from the base to the top of the mountain. Find the shortest length of cable needed.

Answers

Answer 1

Answer:

3917m

Step-by-step explanation:

We are given that

[tex]\theta=74^{\circ}[/tex]

[tex]h=3400 ft[/tex]

We have to find the shortest length of cable needed.

Let Base=x

We know that

[tex]tan\theta=\frac{Perpendicular\;side}{Base}[/tex]

Using the formula

[tex]tan74^{\circ}=\frac{3400}{x}[/tex]

[tex]x=\frac{3400}{tan74}=975m[/tex]

[tex]y=x+970=975+970=1945m[/tex]

Now, the length of cable needed

=[tex]\sqrt{(3400)^2+(1945)^2}[/tex]

=3917m

Hence, the shortest length of cable needed=3917m

What is area?

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

here, we have,

Given that Area of the square mirror = 256 square inches

We know that area of square is given by formula

Area = x^2, where x is the side of the square

plug the given value

256=x^2

take square root

16=x

Hence width of the square is 16 inches.

Given that a rectangular mirror has a width the same as the square mirrors width.

Then width of the rectangle = 16 inches

Length of the rectangle = 16+2 = 18 inches

Area of rectangle = Length * width = 16*18 = 288

Hence final answer is 288 square inches.

Group of answer choices

28

Answers

Answer:

100 red bricks

Step-by-step explanation:

Let's say red bricks is equal to 5x

Gray bricks is equal to 2x

We have an equation

2x + 5x = 140

= 7x = 140

Divide through by 7 to get the value of x

X = 140/7

X = 20

Red bricks = 5(x)

= 5(20)

= 100

Gray bricks = 2(x)

= 2(20)

= 40

Therefore in conclusion the number of red bricks is 100.

The population of a suburb is 4000 people. The population of the suburb

is expected to double each decade. The expression 4000 • 2d models the

population of the suburb after each decade d.


Please Answer: Evaluate the expression for

d = –2.

Answers

Answer:

1000

Step-by-step explanation:

The population of the suburb after each decade d is given by the equation as follows :

[tex]P=4000\times 2^d[/tex]

We need to evaluate the expression for d = -2.

Put d = -2 in the above equation. So,

[tex]P=4000\times 2^{-2}\\\\=4000\times \dfrac{1}{2^2}\\\\=4000\times \dfrac{1}{4}\\\\=1000[/tex]

So, if d = -2, then the population of the suburb is equal to 1000.

The perimeter of a isclose triangle is 24in and the length of the side is 4 in find the 2 other sides

Step-by-step explanation:

Given

Shape: Isosceles Triangle

[tex]Perimeter=24\ in[/tex]

[tex]Side = 4\ in[/tex]

Required

Find the length of the other two sides

Represent the other sides with x.

Since it is an isosceles triangle, 2 sides are equal.

So, we have:

[tex]x + x + 4 = 24[/tex]

[tex]2x + 4 = 24[/tex]

Collect Like Terms

[tex]2x = 24-4[/tex]

[tex]2x = 20[/tex]

Divide both sides by 2

[tex]\frac{2x}{2} = \frac{20}{2}[/tex]

[tex]x = \frac{20}{2}[/tex]

[tex]x = 10[/tex]

The other sides are 10in each
