Answer:
The score of the dropped grade is 6
Step-by-step explanation:
To find the average of a set of numbers you need to add all the numbers and divide by how many numbers there are. The problem wants you to solve it in reverse. Let put this into an algebraic equation with a, b, c, d, and e being the variables of the test scores
(a+b+c+d+e)/5=10
Then we can multiply both sides by 5 and get
a+b+c+d+e=50
Lets assume that c is the lowest test score. To calculate the average of that we get
a+b+d+e/4=11
Doing the same thing, we know that a+b+d+e=44
Now compare the two:
a+b+c+d+e=50
a+b+d+e=44
We can now know that c=50-44=6
So, 6 is the score of the dropped quiz. Hope that helped!
Answer:
4rth 6(5+2)
Step-by-step explanation:
This is because 6 rows of 5 squares means that there is 6 rows with 5 squares each. 6 × 5 = 30. Then there is another set of 6 rows with 2 squares in each, which is 6 × 2 = 12. 30 + 12 = 42. Which is why 6(5+2) = 42. 6(5+2) = 6(5) + 6(2) = 6(7) = 6 × 7 = 6 + 6 + 6 + 6 + 6 + 6 + 6 or 7 + 7 + 7 + 7 + 7 + 7 or 5 + 5 + 5 + 5 + 5 + 2 + 2 + 2 + 2 + 2 + 2 = 42.
Answer:
no
Step-by-step explanation:
If this were a right triangle we would assume the Pythagorean Theorem to prove it
this gives us
49+64=84.64
this is 143=84.64 and therefore not equal and not a right triangle
