Tim would have to do 18 chores (2 chores 9 times or 1 chore 18 times) to be able to buy the video game.
Step-by-step explanation:
Step 1; Tim's parents will give him $3 for every two chores. This equals $1.50 for a single chore. He wants to save up $27 so that he can buy the video games he wants.
Step 2; The number of times he has to do the chores to be able to but the video game is a division between the money he wants to save up by the money he gets for the chores.
Number of 2 chores he needs to do = Amount of money he wants to save up / money he gets for doing two chores
= $27 / $3 = 9 times.
Number of single chores he has to do =Amount of money he wants to save up / money he gets for doing two chores
$27 / $1.50 = 18 times
Commutative transformation is type of transformation in which the order of operations doesn't affect the result of transformation.
The only commutative transformation is D.
17 + 2 = 19 km is 1/2 of the total length, that is,
19 = (1/2)h
(1/2)h = 19 multiply both sides by 2
h = 2*19
h = 38 km
The total length in kilometers is 38 km
Answer:
a. 601
b.
Step-by-step explanation:
a. The number of students in the school who study french:
The number of boys who study french + The number of girls who study french:
= (3÷7)×644+(5÷8)×520

= P(boy does not study french) + P(girl does not study french)
Answer:
9.22
Step-by-step explanation:
First, let's establish the distance formula! The distance formula is . Now, let's input our variables into the formula.
<em> (Also, we changed the minus sign to a plus sign because we have a negative number and we know that a negative minus a negative is a positive!)</em> Now we can start to solve the equations!
1st. We need to solve inside the parenthesis of both the x parenthesis and the y parenthesis.
2nd. We should square the inside of both of the parenthesis!
<em>(Remeber that when you square a negative you get a positive)</em>
3rd. Then, we can add 49 and 36!
4th. Lastly, we are going to find the square root of 85.
d ≈ 9.22 <em>(Remember that "≈" means the round solution, in this case we are rounding to the nearest 100th!)</em>
