A pole 3 m high has a shadow 5 m long when the shadow of a nearby building is 110 m long. How tall is the building? Which of the following proportions could be used to solve the problem? 3/110 = x/5 3/x = 110/5 x/3 = 110/5
Answers
(pole:building) = (pole shadow:building shadow)
(pole:pole shadow) = (building:building shadow)
or the reverse of these.
The appropriate choice is ...
x/3 = 110/5 . . . . (building:pole) = (building shadow:pole shadow)
Answer:
Step-by-step explanation:
Given : A pole 3 m high has a shadow 5 m long
The shadow of a nearby building is 110 m long.
To Find: How tall is the building?
Solution:
Let the height of building be x
A pole 3 m high has a shadow 5 m long
The shadow of a nearby building is 110 m long.
Height of pole and length of shadow has direct variation
So, A.T.Q
or
Hence Option C is correct

Sadly, you didn't put any sums on your list of choices.
In fact, I can't even find a list of choices !

Answer:
Point R located on ray PQ.
Step-by-step explanation:
Given : Diagram
To find : Which point is located on ray PQ.
Solution : We have given <--------M---------N---------O------P--------Q----------R--------S--------->.
Ray : A part of a line with a start point but no end point (it goes to infinity).
We can see from the diagram ray PQ start from P but it has no end point.
So , point R ans S located on ray PQ but we have option R
Therefore, D. point R located on ray PQ.

9 more than so 9+30 so 39÷10 so 3.9
Step-by-step explanation:
- Nine more than thirty divided by ten
This is not algebra but a simple expression, but written like this it has 2 interpretations, so in mathematics numbers and signs are used instead of words, the two expressions could be 9 + 30 : 10 = or (9 + 30) : 10 =
9 + 30 : 10 = (remember PEMDAS)
9 + 3 =
12
(9 + 30) : 10 =
39 : 10 =
39/10 or 3.9

Answer:
x =22.5
Step-by-step explanation:
x+3x = 90
x and 3x are complementary so they add to 90 degrees
Combine like terms
4x =90
Divide each side by 4
4x/4 = 90/4
x =22.5
answer: x = 22.5
explanation:
as the 3x and x are on a straight line with the angle of 90° we know that
3x +x = 90
4x = 90
x = 22.5
