Answer:
|−70 − 15| = |−85| = 85 units - B
Step-by-step explanation:
<u>Area of triangle = (1/2) × Base × Height</u>
Area of bigger triangle = (1/2) × 15 cm × 10 cm
Area of bigger triangle = (1/2) × 150 sq. cm
Area of bigger triangle = 75 sq. cm
Similarly,
Area of smaller triangle = (1/2) × 12 cm × 5 cm
Area of smaller triangle = (1/2) × 60 sq. cm
Area of smaller triangle = 30 sq. cm
Area of shaded region = Area of bigger triangle - Area of smaller triangle
Area of shaded region = 75 sq. cm - 30 sq. cm
Area of shaded region = 45 sq. cm
<u>Answer</u><u> </u><u>:</u>
Area of shaded region in sq. cm = 45
So first (3 1/2) equals to 3+1/2 which is 7/2, same for(2 1/3), 2+1/3=7/3. It's asking for speed in laps per minute, so like how many labs did she swim per minute, which is labs over time——(7/2)/(7/3)=(7/2)*(3/7)=3/2. So she swam 3/2 labs per minute.
