Answer:
A
Step-by-step explanation:
Collecting terms of the expression, we have ...
x + 0.1x = x(1 +0.1) = 1.1x
In words, adding 10% is the same as multiplying the value by 1.1. Choice A is appropriate.
Degree of the Term is the sum of the exponents of the variables. 2x 4y 3 4 + 3 = 7 7 is the degree of the term. 5x-2y 5 NOT A TERM because it has a negative exponent. 8 If a term consists only of a non-zero number (known as a constant term) its degree is 0. Your welcome!
Which number means four hundred seven and six hundred fifty-two thousandths?
answer is
407.652
Loretta:
Average driving speed = 55 mph
Time = 4 hours
Distance traveled = 55*4 = 220 miles
Dad:
Average driving speed = 65 mph
Let x = hours driven
Distance traveled = 65x miles
The length of the trip is 610 miles, therefore
65x + 220 = 610
65x = 390
x = 6 hours
Answer: Loretta's dad drove for 6 hours.
Answer:
The profit per year will be $23916
Step-by-step explanation:
Cost price of 1 ft³ = $2.05
Selling price of 1 ft³ = $21.98
Profit = Selling price - cost price
profit = $21.98 - $2.05
Profit = $19.93
Profit on 1 ft³ is $19.93
If they sell 100 monthly, per year (12 months), profit will be
19.93*100*12
= $23916
