The answer is -5/4 and that was easy
Answer:
48
Step-by-step explanation:
Here we will show you how to calculate 8 divided by 1/6. We will give you the answer in fraction form and in decimal form.
Here is 8 divided by 1/6 displayed mathematically in colors:
8
÷
1
6
The numbers in 8 divided by 1/6 are labeled below:
8 = whole number
1 = numerator
6 = denominator
To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:
8 x 6
1
=
48
1
Thus, the answer to 8 divided by 1/6 in fraction form is:
48
1
To make the answer to 8 divided by 1/6 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:
48 / 1 = 48
The answer is rounded to the nearest two decimal points if necessary.
48/1 is an improper fraction and should be written as 48.
im not really sure about this since i think you can just stop at equation 1
Answer:
A = P * a / 2
A = 81.25
Step-by-step explanation:
We have that there is a corresponding formula for a regular decagon, which depends on the apothem and the perimeter, it is the following:
A = P * a / 2
In this case, the perimeter is the sum of all the sides, that is, 10 sides, therefore:
P = 10 * 3.25
P = 32.5 meters
We replace:
A = 32.5 * 5/2
A = 81.25
Which means that for that regular decagon, the area is 81.25 square meters.
Answer:
sail a = 81ft²
sail b base = 12ft
Step-by-step explanation:
question 5:
the measurements for sail A are 18ft(height) and 9ft (base)
the formula to find the the area of a triangle is (b · h) 1/2
(9 · 18) 1/2 = (162) 1/2 = 81
so ahmad will need 81ft² of fabric for sail a
question 6:
we know that the formula to find the area of a triangle is (b · h) 1/2 = a, since we know the height and the area of the triangle we plug them into the equation to find the measurement of the base.
(b · 18) 1/2 = 108
= 108/ 1/2
(b · 18) = 216
18b = 216
18b/18 = 216/18
b= 12
check your work:
(12 · 18) 1/2 = 108
(216) 1/2 = 108
108 = 108 true!
the base measurement for sail b is 12ft
hope this helps and have a great day!!
