Answer:
1.861(10²)
Step-by-step explanation:
Proper scientific notation only has the ones place and decimals. To get the same value again, we would need the exponent to be 2 and not -2.
The answer is "If it does not have four legs, then an animal is not a deer."
To form the contrapositive, switch the hypothesis and the conclusion and negate both.
The hypothesis is the "if" part and the conclusion is the "then" part.
Set up two equations:
1st: P (for Price family) + J (for Jenkins family) = 45 hours
2nd: 20P + 35J = 1200 liters
Rewrite the first equation as P = 45 – J
Replace P in the second equation:
20(45-J) + 35J = 1200
Simplify:
900 -20J + 35J = 1200
900 +15J = 1200
Subtract 900 from both sides:
15J = 300
Divide both sides by 15:
J = 300/15
J = 20
Jenkins used theirs for 20 hours
Price used theirs for 45-20 = 25 hours.
To get the answer you divide the cds by 2 because the CD's are 1/2 in thick to get: 26 in
Divide 6 by -8 to get the variable alone!
6/-8 < division< equation
