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

BlackZzzverrR [31]

Step-by-step explanation:

\frac{8}{3 - 4x}  =  \frac{5}{2x + .25}  \\ 8(2x + .25) = 5(3 - 4x) \\ 16x + 2 = 15 - 20x \\ 16x + 20x = 15 - 2 \\ 36x = 13 \\ x =  \frac{13}{36}

The scale of a map is 1 inch : 9.5 miles.
DedPeter [7]

Answer:

  • 2.526 in
  • 4.211 in

Step-by-step explanation:

To find the number of inches, divide miles by 9.5.

__

a) 24 miles = (24 mi)×(1 in)/(9.5 mi) = (24/9.5) in ≈ 2.526 in

__

b) 24 miles + 16 miles = 40 miles = (40 mi)×(1 in)/(9.5 mi) = 40/9.5 in ≈ 4.211 in

_____

Comment on units conversion

I find it convenient to work units conversion problems by writing a fraction that is equal to 1 and multiplying by that to change units. My fraction has the "to" units in the numerator, and the "from" units in the denominator. That way, the unwanted units cancel when the multiplication is carried out.

The fraction is equal to 1 because the measurement in the numerator is equal to the measurement in the denominator.

__

Some folks prefer proportions. If you do it that way, be sure "like" is matched with "like".

  map inches/ground miles = 1/9.5 = x/24

  route inches/scale inches = route miles/scale miles = x/1 = 24/9.5
