To determine the next smaller scale size following the scale size equal to 2.353, we just have to divide this scale size by the scale factor which is given to be 1.33. That is, smaller scale size = 2.353 / 1.33 = 1.77Thus, the next smaller scale size is approximately 1.77.

Model H shows equal expressions
25% means 1/4
divide 268 with 4 and the answer is
67
D. $8,962.50
P stands for principal
R stands for rate
T stands for time
A=$7,500(1+ (0.039×5))=$8,962.5
A=$8,962.50
So Jake will have $8,962.50 of interest after 5 years.
Answer:
width = 2 cm
Step-by-step explanation:
are of rectangle is equal to length times width
x is the width, then length is 3x + 4
so x(3x + 4) = 20
3x^2 + 4x = 20
3x^2 + 4x - 20 = 0
The formula to solve a quadratic equation of the form ax^2 + bx + c = 0 is equal to x = [-b +/-√(b^2 - 4ac)]/2a
so a = 3
b = 4
c = -20
substitute in the formula
x = [-4 +/-√(4^2 - 4(3)(-20))]/2(3)
x = [-4 +/- √(16 + 240)]/6
x = [-4 +/- 16]/6
x1 = (-4 + 16)/6 = 2
x2 = (-4 - 16)/6 = -20/6
since the width can't be a negative number, x2 is not the right answer
so x = 2
