Answer:
93
Step-by-step explanation:
The mean of a list of numbers is the sum of the numbers divided by the count of the numbers in the list.
In this case, representing the eighth score with x, the mean is (611+x)/8
Solving for the mean:
88=(611+x)/8
Multiply both sides by 8
8*88=611+x
704=611+x
704-611=x
x=93

Answer:
9 feet
Step-by-step explanation:
Area of a parallelogram = base times height
Thus, 54 = 6h
where h = height
* divide each side by 6 *
54 / 6 = 9
6h / 6 = h
h = 9
Thus, the answer is A
Answer:
Similar states:
- They have the same geometric shape.
- Their corresponding sides are in proportion.
Given the statement: Pentagon JKLMN is similar to pentagon STUVW .
If NJ = 4 units WS = 3 units and JK = 5 units.
We have to find ST.
By definition of similar;
.
then;
Substitute the given values, to solve for ST;
By cross multiply we have;
Divide both sides by 4 we get;
Therefore, the value of ST = 3.75 units
