Answer:
The answer is \frac{2A}{h} -b_2=b_1
Step-by-step explanation:
Given that the area of a trapezoid is ;
A=1/2 (b₁+b₂)h
When the equation is solved for b₁ it will be;
A=1/2 (b₁+b₂)h
This can be written as;
A=h/2 (b₁+b₂)
Multiply both sides by 2/h
2A/h = b₁+b₂
Make b₁ subject of the formula
2A/h - b₂ = b₁
Answer:
1,111 cm cubed
Hope it helps!
Step-by-step explanation:
1.02 (radius) cubed x 3.14 x 4/3 (sphere volume formula)
=4.44292416 cm cubed
4.44292416 x 250 (magnets amount) = 1,110.73104
1,110.73104 rounded to nearest whole cubic unit
1,111 cm cubed

Answer:
(3, 2)
Step-by-step explanation:
3x-y=7
2x-2y=2
------------
y=3x-7
substitute this equation to 2x-2y=2
first, simplify 2x-2y=2 into x-y=1.
-----------------------------------------------------
x-(3x-7)=1
x-3x+7=1
-2x+7=1
-2x=1-7
-2x=-6
x=-6/-2=3
y=3(3)-7=9-7=2
Answer: x=3, y=2.
