The sun shines at a 30° angle to the ground. To the nearest inch, how long is the shadow cast by a 72-inch tall fence post?

murzikaleks [220]

the shadow cast by a 72-inch tall fence post is of 125 inch!

<u>Step-by-step explanation:</u>

Here we have , The sun shines at a 30° angle to the ground. To the nearest inch, We need to find how long is the shadow cast by a 72-inch tall fence post. Let's find out:

According to question we have a right angle triangle with following parameters :

$Perpendicular = 72 inch\\Base = ?\\x =30$

We know that

⇒ $Tanx = \frac{Perpendicular}{Base }$

⇒ $Tan30 = \frac{72}{Base }$

⇒ $\frac{1}{\sqrt{3} } = \frac{72}{Base }$

⇒ $Base = 72\sqrt{3} inch$

⇒ $Base = 124.7 inch$

Rounding off we get :

⇒ $Base = 125 inch$

Therefore , the shadow cast by a 72-inch tall fence post is of 125 inch!

A student's scores on five tests are 98, 99, 86, 89 and 70. What must the score be on the next test so that the average is 8

vitfil [10]

Answer:

x = 86

Step-by-step explanation:

The average of a set of data is equal to the sum of the numbers divided by

number of the sample . In our case we have

98 , 99 , 86 , 89 , 70 and x the uknown, and we know that the average need to be 88 so

(98+99+86+89+70+x ) / 6 = 88

442 + x = 528

x = 528 - 442

x = 86

butalik [34]

Answer:

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.

Please have a look at the attached photo.

My answer:

We need to find the total surface area of the building a skateboard ramp without its bottom.

The Area of the slope: 10.5*25 = 262.5 $ft^{2}$
The Area of the two triangles: 2 ( $\frac{1}{2} 7*24$ ) = 168 $ft^{2}$
The Area of the back: 10.5*7 = 73.5 $ft^{2}$

So the total surface area is: 262.5 + 168 +73.5 = 504 $ft^{2}$

Hence, the number quarts of paint will mario needs to buy is:

504/85 ≈ 6

Hope it will find you well
