Answer:
B 8.56
this is the answer because you simply add what he bought so 1.13+1.13+1.76 which is 4.02 then subtract what he started with which was 12.58 so 12.58-4.02 is 8.56 so that's your answer
Answer:
20 minutes
Step-by-step explanation:
Remember that

we know that
Hector has 3/4 hour to spend his homework
Convert to minutes

so
1) He wants to spend 1/3 of this time on math homework
To find out the time on math homework, multiply 45 minutes by 1/3

2) He wants to spend 10 minutes of his time on reading homework
3) He wants to spend the remaining time on science homework
The time spend on math homework plus the time spend reading homework, plus the time spend on his science homework must be equal to 45 minutes
Let
x ----> the time spend on his science homework

Solve for x

74,233 increased by 58,490 is 74,233 * 58,490 so its 4,341,888, 170. So 4 billion, 341 million, 888 thousand, 170.
Scientific notation is 4.34188817 * 10 to the 9th power.

What percent of 150=6
X/100 * 150=6
/150. /150
X/100=0.04
X/100 *100/1 =0.04* 100/1
X=4
4% of 150=6
That means that for every dollar they take 4 cents from each dollar
150*4 pennies would equal 600 pennies or 6$ or 6.00
Hope this helps!
