Answer:
15.3feet
Step-by-step explanation:
Given the scale model of a train as;
2cm = 3feet
We are to find the height of real train of height 10.2cm, we can write;
10.2cm = x
Divide both expressions
2/10.2 = 3/x
2x = 3×10.2
2x = 30.6
x= 15.3
Hence the height if the real train is 15.3feet
Answer:I think that each friend would get 1.5/ 1 1/2.
Step-by-step explanation:
3 divided by 2 equals 1.5
The two angles form a right triangle which is 90 degrees.
Add the two to equal 90:
3x-8 + 4x = 90
simplify:
7x-8 = 90
Add 8 to both sides:
7x = 98
Divide both sides by 7:
x = 14
Answer:
Blue fabric (triangles) = 27 m²
Green fabric (square) = 9 m²
Step-by-step explanation:
✔️Blue fabric (triangles) = 4(area of triangular face)
= 4(½*b*h)
b = 3 m
h = 4.5 m
= 4(½*3*4.5)
= 27 m²
✔️Green fabric (square) = area of the square base
= s²
s = 3
Area = 3²
= 9 m²
4.75 Kilometers, you just divide by 1000
