Answer:
The length of the actual building is 112 meters long.
Step-by-step explanation:
The key words we need to know are these : scale is 1 millimeter = 7 meters, and 16 millimeters long.
The question is asking for the building's actual height.
To solve this, we need to set up a ratio, have the scale being one ratio and the other 16 millimeters over blank. It's going to look like this :
=
We need to make sure all the units are lined up - the mm parts of the ratio are next to each other.
Now that we have our ratio set up we can cross product to solve for x.
1(x) = 16(7)
x = 112
So x is 112, or the length of the actual building is 112 meters long.
Hope this helps, please mark brainliest if possible. Have a nice day. :)
Answer:
The cost of a shirt is $16 and the cost of a sweater is $33
Step-by-step explanation:
Let
x -----> the cost of a shirt
y -----> the cost of a sweater
we know that
-----> equation A
----> equation B
Solve the system by graphing
Remember that the solution of the system is the intersection point both graphs
The solution is the point (16,33)
see the attached figure
therefore
The cost of a shirt is $16 and the cost of a sweater is $33
