Answer:
92.75 cm^2
Step-by-step explanation:
Area of triangle ADC
= (1/2)×4.5×12 = 27
Area of triangle ACB
=(1/2)×12×5 = 30
Find AB using pythagoras theorem on triangle ABC:
AB^2 = 5^2 + 12^2 = 25 + 144
AB^2 = 169
AB = 13cm
Area of triangle AGB
= (1/2)×13×5.5 = 35.75
Total area = sum of the areas of the 3 triangles found above
= 27 + 30 + 35.75 = 92.75 cm^2
Answer: 2 cups of flour
Step-by-step explanation:
2/3 of 3 is 2
Each T shirt costs $21.
Since Martha takes her niece and nephew to a concert, and she buys T-shirts and bumper stickers for them, and the bumper stickers cost $ 1 each, and Martha's niece wants 1 shirt and 4 bumper stickers, and her nephew wants 2 shirts but no bumper stickers, to determine, if Martha's total is $ 67, what is the cost of one shirt, the following calculation must be performed, posing linear equations:
- 1 bumper sticker = $ 1
- 1 T shirt + 4 bumper stickers + 2 T shirts = $ 67
- 1X + 4 x 1 + 2X = 67
- 3X = 67 - 4
- X = 63/3
- X = 21
Therefore, each T shirt costs $21.
