Step-by-step explanation:
area of a triangle is equal to A= 1/2 BH (In other words just multiply the two numbers aka base times height then divide by two)
Answer:
8,663,944,000
Step-by-step explanation:
To round to the nearest thousand, focus on the 943,526. Because it's over 500, round up, making it 944,000.
Answer:
The surface area is
Step-by-step explanation:
we know that
The tent is a triangular prism
see the attached figure to better understand the problem
The surface area of the triangular prism is equal to
where
B is the area of the triangular face
P is the perimeter of the triangular face
L is the length of the prism
<em>Find the area of the triangular face B</em>
<em>Find the perimeter of the triangular face P</em>
we have
substitute the values
The equation of a straight line is y=mx+b, where m is the slope and b is the y intercept. Substitute your value for the slope to give you y=1/4x+b. Now substitute the complete coordinate into this equation and solve for b:
-3=(1/4×7)+b
-3=1.75+b
b=-4.75
So now you have the full equation, y=1/4x-4.75
Now substitute the incomplete coordinate so you can find h:
-1=(1/4×h)-4.75
3.75=1/4h
÷1/4 (which is 0.25 as a decimal)
h=15
