4. In one semester, Doug and Laura spent a combined 230 hours in the tutoring lab. If Doug
IRISSAK [1]

Answer:

80 hours

Step-by-step explanation:

let d represent doug, let l represent laura

first, set up a system of equations representing the problem:

since doug spent 10 less than twice the hours laura did, and we know that the total amount of hours they spent together is 230:

l=2d+10

d+l=230

then solve:

*first i rearranged the equations so i can solve this system of equations using elimination method*

l-2d=10

l+d=230

*subtract*

3d=240

d=80

so, doug spent 80 hours in the lab

13 is the same as 1÷3. What is the exact quotient in decimal form of 1÷3?
meriva

13 is not the same as 1/3! The division symbol is not a symbol used to connect two numbers, it is used to find their quotient. For example, 6/2 would be like saying: You have 6 cookies, and 2 friends. How many cookies does each friend get? The answer is obviously not 62, it is 3! So, the exact quotient is 0.3 repeating. You could memorize this or use the fact that 0.9 repeating is 1.

<h3><u>Explanation</u></h3>
  • Properties of Exponent

{a}^{ \frac{m}{n} }  =  \sqrt[n]{ {a}^{m} }

  • Convert the expressions from radical to exponent form.

9 \sqrt[4]{ {t}^{3} }  \times 7 \sqrt[3]{ {t}^{2} }  \\ 9( {t}^{ \frac{3}{4} } ) \times 7( {t}^{ \frac{2}{3} } )

  • Simplify the expression by multiplying.

63( {t}^{ \frac{3}{4} }  \times  {t}^{ \frac{2}{3} } )  = 63( {t}^{ \frac{3}{4}+\frac{2}{3} } ) \\ 63( {t}^{ \frac{9}{12} + \frac{8}{12} } ) \\ 63( {t}^{ \frac{17}{12} } )Answer[tex] \large \boxed {63 {t}^{ \frac{17}{12} } }
