The area of the scale drawing would be 1080 square centimeters or (1080 cm^2). I got this answer through first finding the area of the classroom in feet (which is A= lw = [18][20] = 360 ft^2) and then I proceeded to converting it to centimeters via given scale factor (3 cm = 1 foot) and had the answer of 1080 centimeters squared.
Answer:
Step-by-step explanation:
step 1:- by using partial fractions
![[tex]\frac{1-x}{x(x^{2}+1) } =\frac{A(x^{2}+1)+(Bx+C)(x }{x(x^{2}+1) }](https://tex.z-dn.net/?f=%5Btex%5D%5Cfrac%7B1-x%7D%7Bx%28x%5E%7B2%7D%2B1%29%20%7D%20%3D%5Cfrac%7BA%28x%5E%7B2%7D%2B1%29%2B%28Bx%2BC%29%28x%20%7D%7Bx%28x%5E%7B2%7D%2B1%29%20%7D)
......(1)
<u>step 2:-</u>
solving on both sides
substitute x =0 value in equation (2)
1=A(1)+0
<u>A=1</u>
comparing x^2 co-efficient on both sides (in equation 2)
0 = A+B
0 = 1+B
B=-1
comparing x co-efficient on both sides (in equation 2)
<u>-</u>1 = C
<u>step 3:-</u>
substitute A,B,C values in equation (1)
now
by using integration formulas
i) by using 
.....(b)
.....(c)
<u>step 4:-</u>
by using above integration formulas (a,b,and c)
we get answer is
Answer:
Step-by-step explanation:
Hey, do you mean what is the final charge? If so, then look at my next steps
If you mean the final charge then first multiply 10% by 360 , basically 10/100 multiplied by $360 which is equals to $36. Since it is interest, add $36 to $360. The answer will be $396. Then you add on the $19 which would bring the total to $415.
Hehe I am no expert but this is what I did . Tried my best

Answer:
x = 28
m<ABC = 57°
Step-by-step explanation:
✔️(2x + 1)° + 33° = 90° (complementary angles)
Solve for x
2x + 1 + 33 = 90
Add like terms
2x + 34 = 90
2x = 90 - 34 (subtraction property of equality)
2x = 56
Divide both sides by 2
x = 28
✔️m<ABC = 2x + 1
Plug in the value of x
m<ABC = 2(28) + 1
= 56 + 1
m<ABC = 57°
