Answer:
6.2
Step-by-step explanation:
Although there's multiple ways to solve this problem, my method will be to simply find the area for the full triangle (the empty + orange triangles) and subtract the area of the smaller, empty triangle.
Now, you that area for a triangle is 1/2*base*height.
To find the measurements for the full triangle, you must add up the bases for the two smaller triangles:
Height is the same for both triangles so Height total = 4 ft.
Now the total area can be calculated:
Area total= 1/2* base_total * height_total
Area total = 1/2 * 5ft * 4 ft
Area total = 20 / 2 = 10 ft squared
Lastly, subtract the area of the empty triangle from the total triangle to find the orange triangle.
Area Empty Triangle = 1/2 * base_empty * height_empty
Area Empty Triangle = 1/2 * 1.9ft * 4 ft = 7.6 ft / 2 = 3.8 ft squared
Area total - Area empty = 10ft^2 - 3.8ft^2 = 6.2 ft squared
Answer: -2?
Step-by-step explanation:
It is 8 percent of 50.
This is 1 way-
<span>4/50=%/100 You now have a proportion. Cross multiply.
50%=400 Replace % with any variable.
50x=400 Now divide both sides of the equation by 50.
x=8
</span><span>
(% is basically the percentage of 4 of 50 over 100. its much easier to solve </span>percentage problems when the percentages are over 100. 100 represents a full percentage.
example- 4 of 100 is 4% of 100)
2nd example-
Since the percentage can be found if over 100 as well (%/100), and since 100 is a multiple of 50, we can do 4 of 50 (which would look like 4/50) and multiply both numbers by 2 to get the percentage. These are our steps:
<u />4/50× 2/2=
8/100
Therefore, 4 of 50 is 8% of 50
