Answer: 1. $45*1.07 | $45(1.07) 2. (0.85)*32 represent the final price of the cake in dollars because (0.85) is the 15% off in decimals.
Step-by-step explanation:
1 if you multiply 45 by 1.07 it will be 48.15 and that's the final cost of the book, same with $45(1.07) is just another way to represent the multiplication.
2 As I said the 0.85 represent the 15% off, and when you multiply it will be less.
Answer:
There is a scale factor of 1
Step-by-step explanation:
the ratio 1:1 means that there is no difference between the two triangles, and that they are congruent.
Eq1
Y intercept -2,0
X intercept 0,2
Slope 1
Eq2
X intercept-2,0
Y intercept 0,2
Slope 1
Volume = (PI * r^2 * h) / 3
r^2 = (3 * Volume) / (PI * h)
r = Square Root (3 * Volume) / (PI * h)
let the length of each shorter side be x
length of longer side= x+14
2(x+14) + 2x = 48
2x + 28 + 2x = 48
4x + 28 = 48
4x = 48-28
4x = 20
x = 5
shorter side = 5cm
