Answer:
91
Step-by-step explanation:
Substitute 4 in place of x
f(4)=20*4+11
f(4)=80+11
f(4)=91
It would round to 5 because 4.999 is closer to 5 than a decimal (idk if that's 100%)
The second one is the correct equation. The constant to the right should be the diameter squared, while the numbers inside the parentheses should be the opposite.
Answer: 112%
Step-by-step explanation:
Let x = the cost of the shoes
If the cost of the sweater is 12% more than the cost of the shoes, then 1.12x is the cost of the sweater.
To convert the 1.12x into a percentage, multiply 1.12 by 100
This gives you: 112%
