Answer:
22/10 or 2 and 1/5
Step-by-step explanation:
To find the perimeter, add all sides together. Since it's a rectangle, the other sides are the same measurement as the ones given. Add 3/10, 3/10, 4/5, and 4/5 together. To do this, find a common denominator. The lowest common denominator is 10 so multiply the 4/5 by 2/2 to get the denominator to be 10. Now, add 3/10, 3/10, 8/10, and 8/10. It adds up to 22/10 but if you don't want an improper fraction, simplify it to 2 and 1/5.
One root is 1.0791561975888, the other is -0.57915619758885.
Answer:
1. 2×3.14×80
=502.4 m
4. 90 pound on Earth weighs 34 pounds on Mars.
If it weighs 135 pounds on earth, it will weigh x pounds on Mars
=90×=135×34
=90x=4590
=x=4590÷90
x=51 pounds
So therefore it weighs 51 pounds on Mars.
Step-by-step explanation:
in question 4 you have to cross multiply
If your cost is $8.00 and you wish to markup that price by 40%, 80% + 40% = 120%. Divide the $8.00 cost by 120% and get the retail price of $15.00. Therefore, the markup amount is $7.00 ($15.00 - $8.00 = $7.00) and the selling price is $15.
