Answer: 5/7
Step-by-step explanation: 7/5 is 1.4, which doesn't make sense as an answer here because it's a number greater than one, while we're looking for a number that can be made into a simple fraction, decimal or percent. 5 x 7 = 35, which also doesn't make sense for the same reasons but also because the answer is a division problem and this is multiplication. 7/7 equals one, which doesn't make sense because Melissa hasn't finished 100% of her homework yet. Therefore, the answer is 5/7.
E. They will be equally dark because when all of those fractions are simplified they equal 1/3
Because the average is 7.7, his total points are equal to 7.7*10=77.
Because 7*10<77<8*10, Luke cannot have scored 8 10s. We now seek to prove that he can score 7 tens.
This leaves him with three tests left, that sum to 7 marks. There are clearly many ways to arrange this - for example, 2, 3, and 3 on the first three tests, then ten on all seven other tests. As this shows that 7 10s works and we have proven that 8 10s does not work, 7 is the maximum amount of 10s Luke could have scored.
Answer:
415$
Step-by-step explanation:
This might seem a bit confusing, and the best thing you can do is simplfy this and pick out all the important information. Here is what I gathered:
So, we know we need 200$.
We also need 115$.
Then we need 100$..
To find how much money we need in total, lets add these all up:
200+115
=
315
315+100
=
415
So the total money we need is 415!
Hope this helps!
