Answer:
28%
Step-by-step explanation:
Hello,
When the item is reduced by 10%, this is like we multiply this price by 1-0.10=0.90
When the item is reduced by 20%, this is like we multiply this price by 1-0.20=0.80
When the item is reduced by 10% and then by 20%, this is like we multiply this price by 0.90*0.80=0.72
so this is equivalent that the item is reduced by 28% (as 1-0.28=0.72)
hope this helps
Answer:
A and C.
Step-by-step explanation:
to get rid of the square root & n, you would have to multiply it by n on both sides of the equation, giving you r^n=a.
also to get rid of the square root & n, you can also multiply both sides of a and r by the exponential fraction with n as the denominator:
![\sqrt[n]{a} =r \\(a)^\frac{1}{n} = r\\a\frac{1}{n} = r](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%7D%20%3Dr%20%5C%5C%28a%29%5E%5Cfrac%7B1%7D%7Bn%7D%20%3D%20r%5C%5Ca%5Cfrac%7B1%7D%7Bn%7D%20%3D%20r)
We are given that the temperature is less than (<) -3 degrees Fahrenheit.
Since the temperature is represented by the variable "t", then t is less than -3.
So, the inequality which best describes the situation is:
t < -3
Checking the choices, we will find that the correct choice is:
<span>C: t < -3</span>
85.8 is the answer to this question
6 / 4.5 = x / 6
x = 6* 6 / 4.5
x = 36/4.5
x = 8
SF = 4.5 / 6 = 0.75
answer
<span>A. Scale factor 0.75, x = 8</span>
