In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data
7.1 x 10-3
standard form = ?
Step 02:
standard form
7.1 x 10-3 ====> 0,0071
The answer is:
0,0071
Answer:
A. 24
Step-by-step explanation:
Angles in a triangle add up to equal 180
Thus, 66 + 90 + x = 180
66 + 90 = 156
156 + x = 180
180 - 156 = 24
Hence, x = 24
Note: There is a right angle indicated by the square inside of the triangle. A right angle has a measure of 90 degrees. So Just in case you were wondering that's where the 90 cam from
SOLUTION
From the question given, the cost of the toy truck is $36.50 before tax.
Now, the store selling the toy truck adds a 6% sales tax. This means

Now, we will add this $2.19 to the initial cost, we have

This gives $38.69.
Finally we will do a discount of 10%. 10% discount is

We will then subtract this 3.869 from 38.69, we get

That is 34.821. The 1 which is the last number at the decimal part is less than 5, so we ignore it and our answer becomes $34.82
I would say the third one would be the correct or the second one
