Answer:

558.01 ft

Step-by-step explanation:

To obtain the height of cell tower :

Height of post / shadow of post = height of tower / shadow of tower

Shadow of post = 16 in = 1.333333 ft

6/ 1.3333 = height of tower / 124

6 * 124 = 1. 3333 * height of tower

744 = 1.3333 * height of tower

Height of tower = 744 / 1.3333

Height of tower = 558.01

Height of tower = 558.01 ft

37000 + 37000\(0.09)

is the answer.

Answer:

tan

Step-by-step explanation:

you can use this equation

[tex]tan(18) = \frac{h}{100} [/tex]

to solve for h

Answer:

Tangent

Step-by-step explanation:

Tangent=opposite/adjacent

For the angle that's 18°, it's opposite side is h, and the side that is next to, or adjacent to it is 100. It's not the other side because that's hypotenuse.

When you plug those in, you'll have:

[tex]tan(18)=\frac{h}{100}[/tex]

Solve for h by multiplying both sides by 100 to get:

[tex]100*tan(18)=h[/tex]

Put [tex]tan(18)[/tex] into calculator to get .324919. When you do so, make sure you're in degrees, not radians.

Since we are multiplying that by 100, the final answer is 32.4919

[tex]\frac{2}{3}[/tex] of grapes

[tex]\frac{1}{4}[/tex] of apples

[tex]\frac{1}{2}[/tex] of orange

when adding fractions, make sure all denominators are the same:

[tex]\frac{2}{3} = \frac{8}{12}[/tex] of grapes

[tex]\frac{1}{4} = \frac{3}{12}[/tex] of apples

[tex]\frac{1}{2} = \frac{6}{12}[/tex] of orange

add all of the fractions:

[tex]\frac{30}{12} + \frac{8}{12} + \frac{3}{12} + \frac{6}{12} = \frac{47}{12}[/tex]

convert to mixed fraction:

Answer:

John was 17 miles away from where he started.

Step-by-step explanation:

The easiest approach to this problem is to draw it out (check the attached image). Going East and turning South is the same as drawing a line towards the right, and then down on the paper.

Using the Pythagorean Theorem, we know that the sum of the square of the legs (2 smallest sides of a right triangle) is equal to the square of the hypotenuse of that triangle. In other words, [tex]a^2 + b^2 = c^2[/tex].

So to solve this, work backwards:

[tex]8^{2}+15^{2} =c^{2}\\64 + 225 = c^{2}\\289 = c^{2}\\c = \sqrt{289}\\ c = 17[/tex]

The distance between the initial and final point will be 17 miles.

The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

This can be expressed as

H² = P² + B²

John drove his car due east for 8 miles.

He then turned south and drove 15 miles.

Then the distance between the initial and final point will be

H² = 8² + 15²

H² = 64 + 225

H² = 289

H = 17 miles

Answer:

$23.13

Step-by-step explanation:

in total they would need to pay $23.13

Answer:

$27.41

Step-by-step explanation:

Meal Cost = $86.50

Sales Tax= 6.75% of the Meal Cost

= 6.75% X 86.50

= 0.0675 X 86.50

=$5.84

They tipped the Waiter 20%

20% of 86.50

=0.2 X 86.50

=$17.30

Total Bill= Meal Cost + Sales Tax + Tip

= 86.50 +5.84 + 17.30

=$109.64

Since the friends are four, each one will be expected to pay:

$109.64/4

=$27.41

The man had 4 $5 bills and 16 $1 bills.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Let x be the number of $5 bills and y be the number of $1 bills.

From the problem, we know that:

y = 3x + 4 (since the number of $1 bills was 4 more than 3 times the number of $5 bills)

The total amount of money the man had is $36, so we can write:

5x + 1y = 36

Substituting the first equation into the second equation, we get:

5x + 1(3x + 4) = 36

Simplifying and solving for x, we get:

5x + 3x + 4 = 36

8x = 32

x = 4

So the man had 4 $5 bills.

Using the first equation, we can find the number of $1 bills:

y = 3x + 4 = 3(4) + 4 = 16

Therefore,

The man had 4 $5 bills and 16 $1 bills.

x + 32 = 5x - 40

5x - x = 40 + 32

4x = 72

x = 18

Answer:

8 inches

Step-by-step explanation:

Let w be the width of rectangle B.

Since, both rectangles are similar.

Therefore, corresponding lengths and widths of rectangles A and B will be in proportion.

[tex] \therefore \frac{20}{40} = \frac{4}{w} \\ \\ \frac{1}{2} = \frac{4}{w} \\ \\ w = 2 \times 4 \\ \\ w = 8 \: inches[/tex]

Answer:

8"

Step-by-step explanation:

Lᵃ/Wᵃ = Lᵇ/Wᵇ

20"/4" = 40"/Wᵇ

Wᵇ = (4"×40")/20"

Wᵇ = 160" ÷ 20"

Wᵇ = 8"
