Answer:
(c) Add 3 to 9
Step-by-step explanation:
The order of operations tells you that quantities in parentheses are evaluated first.
Here, that means the first step is finding the sum 3+9.
Answer:
y^8
Step-by-step explanation:
y^4^2
We know a^b^c = a^(b*c)
y^4^2 = y^(4*2) = y^8
Answer:
Take each sale price of each product and divide it by its original price. Subtract from 1. Then multiply by 100.
Step-by-step explanation:
A percent is a portion of 100 or the total. We find the percent we pay by taking each sales price and dividing it by the original price. To find the percent off we take that same number and subtract from 1. This will give a decimal which we can convert to a % by multiplying by 100.
The Pythagorean theorem states that a^2 + b^2 = c^2, where a and b are sides not opposite to the right angle, shown as a square. C represents the hypotenuse, or side opposite of the right angle
We see that a = 14 (it can also be b; both can be plugged in as both are adjacent and not opposite of the right angle)
c = 19; hypotenuse is opposite of right angle
14^2 + b^2 = 19^2
196 + b^2 = 361
b^2 = 361 - 196
b^2 = 165
b = square root of 165
b = 12.845
x = 12.845
I don’t know! This is a very hard question
