6.7x10^6 always the the decimal points go between the first 2 numbers, and you count the numbers of decimal places following it to get your scientific exponent
First, convert the 65% to a real mathematical number. For percents, this is always done by dividing the 65% by 100%, or 65% / 100% = 0.650.
Second, find out what 65% of $60 is. This is the amount of the sale discount. This is always found by mulitplying 0.650 by the item's cost $60, like this:
0.650 x $60 = $39.00.
So for this sale, you'll save $39.00 on this item.
This means, the cost of the item to you is
<span>$60 - $39.00 = $21.00.</span>
The sentence that is true should have something to do with that 10 multiplied by any number is the number being multiplied by 10 with a zero at the end.
All numbers greater than 0 and smaller than 10 multiplied by 10 and their products are
1×10=10
2×10=20
3×10=30
4×10=40
5×10=50
6×10=60
7×10=70
8×10=80
9×10=90
I hope this helps
Answer:
The measure of radius c is 12.36 cm
C is correct.
Step-by-step explanation:
Given: A regular pentagon is shown in diagram.
As we know the sum of angle of pentagon is 540°
It is a regular pentagon. Therefore, each angle is equal.
OB would be angle bisector of angle B
Thus,
In triangle OBC, ∠C=90°
Hence, The measure of radius c is 12.36 cm
