<u>4/5</u>, you divide both by 4 and you get <u>4/5</u>
we can divide the composite shape into on quadrilateral and triangle as shown in the diagram. since the line that joins the two shape is parallel to the base AB, the angle DEC is 85°.The angle CEA is 180°- angle DEC = 180-85=95. Angle BCE is sum of angle CEA, ABC and EAB subtracted from360°= 360°-(95+95+85)=85°. Angle DCE is 120°- ECB=35°. So, angle CDE = 180°-(35°+85°)= 60°. For reference see the diagram.
Answer:
B: 54 square feet
Step-by-step explanation:
There are 3 feet in 1 yard. The scale model is 6 square yards.
Multiply 6 by 3 to get the amount of square yards.
There are 18 square yards in the actual playground.
Since there are 3 feet in a yard, multiply 18 by 3.
This gives you your answer:
54 square feet
<u>Find fraction of snappers and catfish:</u>
1/3 + 2/9 = 3/9 + 2/9 = 5/9
<u>Find fraction of goldfish:</u>
1 - 5/9 = 4/9
4/9 = 40 goldfish
1/9 = 40 ÷ 4 = 10
9/9 = 10 x 9 = 90
Answer: 90 fish in the tank
