Answer:
f(x) = ($23/week)(x)
Step-by-step explanation:
Hello!
Let's determine the unit rate. I'd suggest finding the cost per week, rather than the weeks covered by a certain amount of money.
Then:
$115
-------- = $23 per week
Then the amount spent as a function of the # of weeks would be:
f(x) = ($23/week)(x)
5 wk
(b)+(b+45)=215
b = # of boys
there are 45 more girls than boys and 215 students total.
minus 45 on both sides leaving you with
(b)+(b)=170
combine like terms leaving you with
2b=170
divide both sides by 2
b=85
there were 85 boys
85+45=130
(the 45 for the # of girls more than boys)
there were 130 girls.
The height of Mount Kilimanjaro is 19,340 feet.
To convert to scientific notation move the decimal point so there is only 1 digit to the left of the decimal pint, you then multiply that by 10 raised to the number of spaces you moved the decimal point.
19,340 - Move the decimal point 4 places to the left to get 1.9340
You can remove the 0 at the end to get 1.934
You moved the decimal 4 places so raise 10 to 4 and get the final answer:
1.934 x 10^4
The first choice is the correct one.
