Answer:
area= 264.5 unit square
Step-by-step explanation:
let the width of the rectangle be x units then the length would be 2x units
perimeter = 2(l+b)= 2(2x+x)=2(3x)=6x
69=6x
x=69/6=11.5units
width is 11.5 units and length is 23 units
area= lxb= 11.5* 23= 264.5 units square
22 dollars + 39 dollars = 61 dollars
100-61= 39 dollars. She needs $39 more
Answer:
The cost before tax with tip is $15.21.
Step-by-step explanation:
To calculate percentage, take the percent (17%) and take its decimal form. This means 17% is 0.17 (like 50% would be 0.5). multiply the number you want the percentage of by the decimal form. 13*0.17=2.21. Add this to the cost before tax and before tip. 13.00+2.21=15.21. The cost before tax with tip is $15.21.
