Answer:
A=5
B=4
Step-by-step explanatation
so the 3ft at the front and the 8ft at the back, you do 8-3 which is 5 which will be A and on the side, it is 8ft and since the corner angle is 4ft then B will be 8-4 which is 4
Answer:
No.
Step-by-step explanation:
The exponent of y is 2, which is not 1, so the equation is 2nd degree, <em>not linear</em> (1st degree).
Its impossible to draw a trapezoid with just three right angles.
a trapezoid has 4 sides, which means all the angles inside the trapezoid must add up to 360 degrees.
if you have just 3 right angles (90x3), you already use up 270 degrees. Leaving you with just 90 degrees left, which is also a right angle. That means, there has to be four, if you have at least 3.
Answer:
tons of high steel and 
tons of low steel
Step-by-step explanation:
Let x be the number of tons of high grade steel and y be the number of tons ow low grade steel needed.
In x tons of high grade steel there are
tons of iron
tons of magnese
In y tons of low grade steel there are
tons of iron
tons of magnese
NASA orders 500 tons of steel, so
and specifies that it must be in the proportion 80% iron and 20% magnese, so
From the first equation,
Substitute it into the second equation:
60 percent of 150 is 90. So that means 60 shots do not go in.
