You are paid $78 for 6 and a half hours of work. What is your rate of pay?
Answers
The most important part of the problem lies in the fact that the hours have to be converted to minutes before starting to solve the problem. 1 hour = 60 minutes 6 and half hours = (6 * 60) + 30 minutes = 360 + 30 = 390 minutes So the payment for 390 minutes is = 78 dollars Then The payment for 60 minutes = (78/390) * 60 = 2 * 6 dollars = 12 dollars So the rate of pay given is $12 per hour. I hope the procedure is easy enough for you to understand. You can always use this method for solving similar type of problems.
$78/ (6 1/2 hours)= $12/hour.
The rate of pay is $12 per hour~
what is the value of 4 to the power of 3 multiplied by 4 to the power of -1 multiplied by 5 to the power of -2 divided by 4 to the power of 4 multiplied by 5 to the power of -3 multiplied to the power of 0
Answers
remember try and group like bases and (x^m)(x^n)=x^(m+n) also x^0=1 and (ab)/(cd)=(a/c)(b/d) and (x^m)/(x^n)=x^(m-n) and x^-m=1/(x^m)
simplify a few stuff
on top (4^3)(4^-1)=4^(3-1)=4^2
on bottom (-3)^0=1 which cancels out since 1 times x=x so disregard the (-3)^0
now we have
split into 2 fractions with 4's in one and 5's in other ()() remember the exponential law
first fraction =4^(2-4)=4^-2 second ()=5^(-2-(-3))=5^(-2+3)=5^1=5
now we have (4^-2)(5)=(1/(4^2))(5)=5/(4^2)=5/16

What is 245.3 divided by 5=?
Answers
To do this without a calculator:
5 goes into 2 0 times. 5 goes into 24 4 times with a remainder of 4. 5 goes into 45 9 times 5 goes into 3 0 times 5 goes into 30 6 times
the answer is 49.06
look up long division for more info 049.06 5 ) 245.3 20 45 45 030 30
49.06 5 ) 245.30 -20 45 -45 03 30 -30 0
When you divide into a decimal, just ignore the decimal point doing your work at the bottom. If you run out of decimal places, just add a 0 to the end.
5 doesn't go into 2, so skip to the next part. 5 goes into 24 a total of 4 times. 4 times 5 is 20. 24 minus 20 is 4. Bring down the 5. 5 goes into 45 a total of 9 times. 9 times 5 is 45. 45 minus 45 is 0. Bring down the 3. Bring up the decimal point. 5 doesn't go into 3, so put up a 0. 0 times 5 is 0. 3 minus 0 is 3. Add a zero to the end and bring it down. 5 goes into 30 a total of 6 times. 6 times 5 is 30. 30 minus 30 is 0. We're done!
Your answer is 49.06.
Mr.Smith's art class has a total of 35 students enrolled. Seven of the thirty five are girls. What percent of the class is made up of boys?
Answers
✡ Answer:80% ✡
- - Why?
Well if there is 35 kids in the class and 7 of them are girls, you can subtract 35-7 to get the reaming total of kids, in this case, the boys.
Now we have a fraction of 28/35 28*35. Lets convert it to a percent:
- - We have Divide 28 ÷ 35 = 0.8
Always multiply by 100
0.8*100
- - Solve:
80%
