The total area is 625 because 25 x 5 = 125. 125 x 5 = 625. that is how you get your answer

Lorenzo’s test scores are 90, 83, 88, 74, 68, and 80. If the teacher drops the lowest test score before calculating the mean, wh

madam [21]

To find the mean, add all the values and then divide the sum by how many values you added. In this case, if the teacher drops the lowest score (68) that would leave 5 values. So,

90 + 83 + 88 + 74 + 80 = 415 < this is the total of all (minus the lowest) or Lorenzo's test scores. Now take this number, and divide it by 5 (because we added five tests together):

415 / 5 = 83 < this is the new mean, and also his percentage grade.

Answer: 83

Alternatively, you can list the grades from least to greatest, and cancel one value from each side until you get to the middle.

A regular hexagon has sides of 3 feet. What is the area of the hexagon?

frosja888 [35]

Answer:

$13.5\sqrt{3}\:\text{ft}^{2}$

Step-by-step explanation:

Given: The side of a regular hexagon is 3 feet.

To find: Area of the hexagon

Solution:

It is given that the side of a regular hexagon is 3 feet.

We know that the area of a regular hexagon whose side is a units is $\frac{3\sqrt{3} }{2} a^{2}$

Here, the side is 3 feet

So, area of the regular hexagon

$=\frac{3\sqrt{3} }{2} \times3^{2}$

$=\frac{3\sqrt{3} }{2} \times9$

$=\frac{27\sqrt{3} }{2}$

$=13.5\sqrt{3}\:\text{ft}^{2}$

Hence, area of the regular hexagon is $13.5\sqrt{3}\:\text{ft}^{2}$
