Answer:
Therefore, Kevin spent $56.
Step-by-step explanation:
We know that the Kevin bought 2 pairs of jeans that were originally $40 per pair but were each marked down by $15 and 3 t-shirts for $12 each. He also used a coupon for $10 off his entire purchase.
Therefore, we have 2 pairs of jeans for $15 and 3 t-shirts for $12 each and a coupon for $10 off his entire purchase.
We calculate the total amount he spent.
Therefore, Kevin spent $56.
It would be : -9.3 , -4.125 and -2.25.
Hope This Helps You!
Good Luck Studying :)
To convert our number to scientific notation, we are going to move the decimal point to the right until we have only one non-zero digit to the left of the decimal point, and then, we are going to multiply that number by a negative power of 10 equal to the number of times we moved the decimal point to the right:
<span>
Our number is 0.000000016, so we need to move the decimal point 8 times to the right to have </span>only one non-zero digit to the left of the decimal point (1.6). Since we moved the decimal point eight times to the right, we are going to multiply 1.6 by y a negative power of 10 equal to the number of times we moved the decimal point to the right i.e.
.
So 0.000000016 expressed in scientific notation is 1.6x
, or in calculator notation 1.6E-8
We can conclude that the correct answers are <span>
1.6E-8 and </span><span>
1.6 × 10-8</span>
Answer:
