Total number of apples received by a large grocery store = 2 thousand apples
= 2000 apples.
Total number of boxes of apples received by a neighboring school = 20 boxes
Number of apples in each box = 100 apples
Therefore, the total number of apples received by neighboring school
=
= 2000 apples.
Refer to the image for place value disk chart.

Complete question :
A 25-foot-long footbridge has two diagonal supports that meet in the center of the bridge. Each support makes a 65∘ angle with a short vertical support.
What is the length x of a diagonal support, to the nearest tenth of a foot?
Answer:
13.80 feets
Step-by-step explanation:
Taking either of the triangles formed and attached to the picture, the length of diagonal, x can be obtained using Pythagoras rule :
To obtain x :
Sinθ = opposite / hypotenus
Opposite = 12.5 feets ; hypotenus = x ; θ = 65°
Sin 65 = 12.5 / x
0.9063077 * x = 12.5
x = 12.5 / 0.9063077
x = 13.792225
x = 13.80 feets
