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 :
We know that
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Rounding off we get :
⇒ 
Therefore , the shadow cast by a 72-inch tall fence post is of 125 inch!
The answer is C. because 1.5 is the height while x is next to it to show the multiplication of years to height
There are 10 marbles in the bag all together.
(8/10) = 80% of the marbles in the bag are white.
So if you pull a marble out of the bag, you have an 80% chance
of pulling a white one.
And if you do it many times, you expect that you'll pull
a white one out about 80% of the times.
80% pf 45 times = 0.8 x 45 = 36 times .
Answer:
6
Step-by-step explanation:
Answer: See explanation
Step-by-step explanation:
We will use the formula for an arithmetic sequence which will be:
a + (n - 1)d
where a = unknown
n = 6
d = 4
We then slot them into the formula
a + (6 - 1)4 = 12
a + 5(4) = 12
a + 20 = 12
a = 12 - 20
a = -8
The 6 numbers are
1st term = -8
2nd term = -8 + 4 = -4
3rd term = -4 + 4 = 0
4th term = 0 + 4 = 4
5th term = 4 + 4 = 8
6th term = 8 + 4 = 12
