She made $8,250 this week. 3% of 250,000 is $7,500, you add her weekly pay of $750 and it gives you your answer.
85 x 0.20= 17%
I hope that helped
Answer:
Step-by-step explanation:
The input it taken as the unknown base value, while the output here is the area of the trapezoid. b is therefore the base value, and A( b ) is the area of the trapezoid. Let's formulate the equation for the area of the trapezoid, and isolate the area of the trapezoid. To find the inverse of this function, switch y ( this is A( b ) ) and b, solving for y once more, y ➡ y ⁻ ¹.
y = height 
( ( unknown base value ( b ) + 7 ) / 2 ),
y = 10 ( ( b + 7 ) / 2 )
Now switch the positions of y and b -
b = 10 ( ( y + 7 ) / 2 ) or 
- now that we are going to take the inverse ( y ⁻ ¹ ) or B( a ), b will now be changed to a,
,
Therefore the equation that represents the inverse function will be the following : B(a) = a / 5 - 7

Step-by-step explanation:</h3>
42. The right-angle corner tells you the two marked angles are complementary — they sum to 90°.
(-3x +20)° + (-2x +55)° = 90°
-5x +75 = 90 . . . . . . . . . . collect terms, divide by °
-5x = 15 . . . . . . . . . . . . . . . subtract 75
x = -3 . . . . . divide by the coefficient of x
The angle of interest is (-3x+20)°. Filling in the found value for x, we have ...
(-3·(-3) +20)° = 29° = m∠BDC
___
43. The distributive property is useful for multiplying polynomials.
(x +2)(3x² -4x +5) = x(3x² -4x +5) +2(3x² -4x +5)
= 3x³ -4x² +5x +6x² -8x +10 . . . . . eliminate parentheses
= 3x³ +2x² -3x +10
___
44. Area is the product of length and width, so this becomes a problem in multiplying polynomials.
area = (5a +17)(4a) = 20a² +68a . . . . area in square feet
