Answer: They will travel about 131.18 yards.
Step-by-step explanation:
Given : A football field is 120 yards long by 53 yards wide.
We know that a football field is rectangular in shape.
Each interior angle in a rectangle is a right angle.
Then, by Pythagoras theorem, we have
(Diagonal)² = (Length)² + (Width)²
If a player runs diagonally from one corner to the opposite corner, then the length of the diagonal is given by :-
Hence, they will travel about 131.18 yards.
the upper bound for the length is .
<u>Step-by-step explanation:</u>
Lower and Upper Bounds
Ex:- a mass of 70 kg, rounded to the nearest 10 kg, The upper bound is 75 kg, because 75 kg is the smallest mass that would round up to 80kg.
Here , A length is measured as 21cm correct to 2 significant figures. We need to find what is the upper bound for the length . let's find out:
As discussed above , upper bound for any number will be the smallest value in decimals which will round up to next integer value . So , for 21 :
⇒
21.5 cm on rounding off will give 22 cm . So , the upper bound for the length is .
Answer:
Martha is incorrect.
Amount paid by Renee =
Amount paid by Susan = $297.5
Amount paid by Martha =
Step-by-step explanation:
Given: Renee will pay 40% of the cost. Susan will pay 0.35 of the cost.Martha will pay the remainder of the cost. Martha thinks she will pay 13 of the cost.
To find: Is Martha correct?
To find: amount paid by each of Renee, Susan, and Martha
Solution:
Percentage of an amount paid by Renee = 40%
Percentage of an amount paid by Susan = 35%
So,
Percentage of an amount paid by Martha =
But Martha thinks she will pay 13 of the cost. So, she is incorrect.
Amount paid by Renee =
Amount paid by Susan =
Amount paid by Martha =
