55 miles × 8 hours = 440 miles
So Ben drove 440 miles.
Answer:
75 questions
Step-by-step explanation:
Let x = total number of questions
Multiply the number of questions by the percent she got right to equal the number of questions right
x*84 % = 63
Change to decimal form
.84x = 63
Divide by .84
.84x/.84 = 63/.84
x =75
There are 75 questions
-8a^8b^-2/10a^-4b^-10
= (-8/10) a^(8+4)b^(-2+10)
= -4/5 a^12 b^8
=-4 a^12 b^8 / 5
Answer is A.) -4 a^12 b^8 / 5
Answer: u = i- 100,000
Step-by-step explanation:
Hi, to answer this question we have to write an equation with the information given:
Population of the United States = u
Population of India = i
Since the population of the United States, u, is about one hundred thousand less than the population of India, i, we have to subtract 100,000 (one hundred thousand) to the population of India (i). That expression must be equal to the population of United States (u).
Mathematically speaking:
u = i- 100,000
Feel free to ask for more if needed or if you did not understand something.
One angle in every right triangle is 90, so the other two sum to 180-90=90. Therefore, other angles must be less than 90 degrees, so a is the only possible option.
