Len [333]

Answer:

<h2>12 feet 8 inch long cast a shadow</h2>

Step-by-step explanation:

A person 6 feet tall standing 18 feet away a lamppost cast a 9 foot shadow.

than move 4 feet than total distance is 22 feet

According to trigonometry rule make 30 degree angle

$tan\left ( 30\ \right )^{o}=\frac{p}{b}$

$\left ( \frac{1}{\sqrt{3}} \right )=\left ( \frac{x}{18+4} \right )$

$x\sqrt{3}=22$

than

$x=\frac{22}{\sqrt{3}}$

$=12feet$ $8 inch$ answer

One-third of a number added to itself equals 3 times the difference of the number and seven.

olya-2409 [2.1K]

Answer:

Step-by-step explanation:

Do this step by step.

Let the number = x

1/3 of a number = 1/3 x

Added to itself 1/3x + x

3*(x - 7)

So the equation is

1/3x + x = 3(x - 7) Remove the brackets. Collect 1/3x and x

4/3 x = 3x - 21 Multiply both sides by 3.

4x = 3*(3x - 21) Remove the brackets again

4x = 9x - 63 Subtract 9x from both sides

-5x = -63 Divide by -5

x = -63/-5

x = 12.6

Janice wants to buy carpet for a trapezoid shaped room. The bases of the trapezoid are 12 feet and 14 feet, and the height is 15

Usimov [2.4K]

For this case, the first thing to do is find the area of the trapezoid.
We have then:
$A = (1/2) * (b1 + b2) * (h)
$
Where,
b1: b2: Trapezoid bases
h: height of the trapezoid
Substituting values we have:
$A = (1/2) * (12 + 14) * (15)

A = 195 ft ^ 2$
Then, the cost per square foot is given by:
$C = 5.50A

C = 5.50 * 195

C = 1072.5$
Answer:
The new carpet for the room will cost:
C = 1072.5 $

Solve for the final amount you need to pay. Chinese foos $120 for delivery. You want to pay 15% tip. How much money total money

gogolik [260]

Answer:

Step-by-step explanation:

Given

Delivery amount = $120

Percent tip on the delivery amount = 15%

Tip amount = 15% * 120

Tip amount = 0.15 * 120 = $30

Total money paid = Delivery amount + Tip

Total money paid = $120 + $30

Total money paid = $150

<em>hence the total money you will give the delivery boy is $150</em>
