Answer:
Step-by-step explanation:as we know that arc length is
s=r*∅
as given angle in degree so convert it in radian we get
angle=2.09 rad
r=3.5 cm
hence we get
s=3.5*2.09 =7.315 cm
perimeter of sector = s +d where d=2*r=2*3.5=7 cm
perimeter of sector=7.315+7=14.315 cm

Using the percentage concept, it is found that 40% of Alberto’s income is used to pay for his rent and groceries.
<h3>What is a percentage?</h3>
The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:

In this problem:
- Alberto’s monthly income is $3,200, hence b = 3200.
- He spends 896 + 384 = $1280 in rent and groceries, hence a = 1280.
Then, the percentage is given by:

The sign would be negative
X is in the negative area meaning that when x/y and multiplied by y, it would stay negative since y is positive
