WILL GIVE BRAINLIEST A fence borders a triangular shaped field. A scale drawing of the fence is shown. The scale of the drawing to the actual size of the field is 24mm: 5m SELECT MUTIPLE CHOICE !

12.5 m

17.5 m

20 m

Step-by-step explanation:

Scale of the drawing to the actual size of the field = 24 mm : 5 m

✍️Given an actual length of 96 mm, actual length would be x m.

Thus:

24 mm : 5 m = 96 mm : x m

Cross multiply

Divide both sides by 24

✅

✍️Given an actual length of 84 mm, actual length would be x m.

Thus:

24 mm : 5 m = 84 mm : x m

Cross multiply

Divide both sides by 24

✅

✍️Given an actual length of 60 mm, actual length would be x m.

Thus:

24 mm : 5 m = 60 mm : x m

Cross multiply

Divide both sides by 24

✅

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

answer: ratio of volume of cone (with 3 times the height and equal diameter) to volume of cylinder is 2 to 1. the value of π is not used.

step-by-step explanation:

radius is diameter/2 = 4.

area of circle is π r^2.

volume of cylinder is height × area of base = hπr^2 = 3(4^2) π = 48π cubic inches.

not knowing the formula for volume of cone, i calculate it using calculus (which is for calculating things).

volume of cone is integral 0 to h area(y) dy. area(y) is π r(y)^2. r(y) runs r to zero as y runs zero to h, r(0) = r, r(h) = 0.

r(y) = r - r/h y

area(y) = π (r - r/h y)^2 = π (r^2 - 2r^2y/h + r^2y^2/h^2) = π r^2(1-2y/h+y^2/h^2)

antiderivative area(y) = π r^2 (y-y^2/h+y^3/(3h^2))

integral 0 to h = π r^2(h-h^2/h+h^3/(3h^2) - (0)) = π r^2(h - h + h/3) = π r^2(h/3) = π/3 r^2 h

volume of this cone is π/3(4^2)18 cubic inches.

= 6 16 π = 96π cubic inches.

cone has twice the volume, 96/48.

cone height is 6 times the cylinder.

ratio of volume formula: π r^2 cancels.

cone over cylinder ratio is 6h/3 to h, 2 to 1.
