88, 10 times 8 is 80. both weeks would be 80 + 8. 88
All real numbers less than 20 has been represented by the graph.
Option B is correct.
Step-by-step explanation:
The graph shown on the number line has unfilled circle on 20 and moves towards the left side of number line.
The unfilled circle shows that 20 is not included
While the graph moving towards left indicates that the numbers are decreasing and are less than 20
So, All real numbers less than 20 has been represented by the graph.
Option B is correct.

Answer:
4 feet
Step-by-step explanation:
see the attached figure with letter to better understand the problem
we know that
A board is half way up each ladder
so
point B is the midpoint segment AC and point F is the midpoint segment AG
Than means
AB=AC/2 -----> AB=10/2=5 units
BF is parallel to segment CG ----> by Triangle midpoint segment theorem
step 1
In the right triangle ABD
Find the length side AD
Applying Pythagorean Theorem
solve for AD
step 2
Find the length of segment DE (h)
Remember that
If two triangles are similar, then the ratio of its corresponding sides is proportional
In this problem
Triangles ABD and ACE are similar by AA Similarity Theorem
so
substitute the given values
----> by segment addition postulate
substitute
solve for DE
therefore
The distance from the bucket to the ground is 4 feet
