Answer:
Number 4 is a right triangle whether 3 isnt.
Step-by-step explanation:
I just know this because a right triangle is always gonna have a 90 degree angle whether that number 3 doesnt have one
43.78 = forty three and seventy eight hundredths.
Answer:
the first option
Step-by-step explanation:
Given
Ax + By = C ( subtract By from both sides )
Ax = C - By ( divide both sides by A )
x = 
Answer:
<h3> __</h3><h3>0.63</h3>
Step-by-step explanation:
7/11 = no, add 0
70/11 = 6, so 0.6, remainder is 4, add 0
40/11 = 3, so 0.03, remainder is 7, add 0
70/11 = 6... and it goes on
<h3>The answer is 0.63 bar notation on both 6 and 3</h3>
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
