Answer:
Nevan does not win
He scored 74 points
Step-by-step explanation:
First, find how many points he gets from 58 correct questions:
Multiply 1 3/4 by 58:
58(1.75)
= 101.5
Then, find how many points he loses from 22 incorrect questions:
Multiply -1 1/4 by 22:
22(-1.25)
= -27.5
Then, subtract 27.5 from 101.5 to find how many points he scored:
101.5 - 27.5
= 74
Since he needed 90 points to win, he did not win because he only got 74.
Answer:
D E + E F greater-than D F
5 less-than D F less-than 13
Triangle D E F is a scalene triangle
Step-by-step explanation:
we know that
The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side
we have the triangle EDF
where
<u><em>Applying the triangle inequality theorem</em></u>
1)
2)
so
The length of DF is the interval -----> (5,13)
The triangle DEF is a scalene triangle (the three length sides are different)
therefore
<em>The statements that are true are</em>
D E + E F greater-than D F
5 less-than D F less-than 13
Triangle D E F is a scalene triangle
