Let ABC be the triangle (with A as summit) and BC its base which is at the same time the diameter of the semi-circle. Let AH be the altitude of ABC.
Length of the Base BC (which is also the diameter of the semi circle) = 4 units and consequently the radius = 2 units
Length of the altitude AH = 5 units, hence:
a) the Area of ABC = (Base x Altitude)/2 = (4 x 5)/2 = 10 units²
b) the area of the semi circle is: (π x R²)/2 = (π x 2²)/2 = 6.28 units²
Total area = 16.28 units²
Answer:
12
Step-by-step explanation:
this is very simple. since the angles are opposite the intersection of two lines, you know they must be equal.
therefore:
97 = 8t +1
solve for t:
t = 12
Answer:
Step-by-step explanation:
A= 10(9+4)/2 = 130/2 = 65
If a 1.8 ounce jar costs $4.05, you want to do $4.05 divided by 1.8. That will give you the cost per ounce.
$4.05 / 1.8 = $2.25 per ounce.
[2,-1 [-5,4 would be the answer because for you to be able to see where your line is going to go you have to finish it
