B. it’s the change in y over the change in x
If the sale was for 30% off, then she paid 70% of the regular price
100%-30%=70% or 0.70
72*0.70=$50.40
Answer= $50.40
Answer:
Calving earning = 4400
Betty earning = 9400
Albert earning = 4700
Donna = 8800
Step-by-step explanation:
Given that :
Calving earning = c
Betty earning = c + 5000
Albert earning = (c + 5000) /2
Donna = 2c
c + 5000 + (c + 5000) /2 = 900 + c + 2c
c + 5000 + 0.5c + 2500 = 900 + 3c
1.5c + 7500 = 900 + 3c
7500 - 900 = 3c - 1.5c
6600 = 1.5c
c = 6600 / 1.5
c = 4400
Calving earning = c = 4400
Betty earning = 4400 + 5000 = 9400
Albert earning = (4400 + 5000) /2 = 4700
Donna = 2(4400) = 8800
Selection A is appropriate.
_____
20*1.1^n is the general expression for the cost n years in the future.
20*1.1^3 = 26.62 is the cost 3 years in the future.
Answer:
Area: 200.96 cm
Circumference: 50.24 cm
Explanation: I recently just learned this. The area of a circle is Pi times radius squared which makes. 3.14 x 8^2 = 3.14 x 64 = 200.96. SInce none of the original measurements are squared it will be 200.96 cm
The circumference of a circle is diameter times pi which makes 3.14 x (8 x 2) = 3.14 x 16 = 50.24. Since none of the original measurements are squared it will be 50.24 cm
I hope this helps! pls mark brainliest if it helps!
