Hint: Find the area and perimeter of the square using the 9 cm. Multiply both of them by 8 to find the actual perimeter and area.
Hint: Divide the 8 and 2 to get the difference in scale. Multiply the 4 by the number you got in step 1 to get the answer.
Hint: Use the formula C = 2r Remember to round!
Hint: Divide the 6 by two to get the radius. Use the formula A = r2 Remember to round!
Hint: These are vertical angles. Vertical angles are equal to each other. Once you set up the equation, solve for x.
Hint: The two angles add up to equal 90. Once you set up the equation, remember to combine the whole numbers before solving for x.
Hint: Find the area of the triangle using the formula A =bh/2 Find the area of the square using the formula A =lw Add the two areas together.
Which is greater, 0.08, or 9/20? Hint: Convert the 9/20 into a decimal by dividing the top number by bottom number. Compare the two decimals to see which is bigger.
Hint: Use the formula I = Prt to find the interest. P is the amount of money, r is the percent as a decimal, and t is the number of years. When you have the interest, add it to the 400 to get the balance.
