A wildlife organization plans to build a boardwalk across a marshland in their community. To measure the distance across the marshland, they set up ropes and pegs as shown in the diagram, and then took the following measurements: DE = 1.2m , DC = 1.5m , BC = 68.0m . If AB is parallel to DE how long is the distance across the marsh AB , to the nearest tenth of a meter?

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.

step-by-step explanation:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.
