Answer:
you don't know the answer?! Come on folk you tweaking.
Step-by-step explanation:
Perimeter=2L+2W
L=W+5, substitute in place of 2L
90=2(W+5)+2W
90=2W+10+2W
90-10=4W
80=4W
80/4=W
W=20, if width is 20 than the length is 20+5=25 cm
Answer:
$939.04
Step-by-step explanation:
To calculate her gross pay, we need to take into consideration, her total pay for the 4 days and her commission based on the total amount of goods she sold.
Firstly, her daily base salary is $85, since she worked for 4 days, her total salary for the four days will be $85 * 4 = $340.
Now, she is to earn 7.2% of $8,320 as commission. The amount of her commission is thus 7.2/100 * 8,320 = 599.04
Her gross pay is thus $599.04 + $340 = $939.04
This is how I would do it;
Convert to minutes 3/5 *60 = 36
Convert this to decimal 2/5 = 0.4
Then;
if it takes 36 mnts to paint 0.4yd^
in 60 mnts x yd^
___________________
60 x 0.4 / 36 = 0.66666667
convert back to fraction = 2/3 yd^ in 1hr
