A sculptor is designing her new triangular masterpiece. In her scale drawing, the shortest side of the triangular piece to be m

Minchanka [31]

Answer:

The shortest side will be 198.82 cm (1.98 m) long

Step-by-step explanation:

This problem can be solved using proportions.

First we have that:

Shortest side in scale drawing = 4 cm

Longest side in scale drawing = 34 cm

Shortest side in actual piece = x cm

Longest side in actual piece = 16.9 m, but we know that 1 meter = 100 cm, therefore 16.9 meters would be 16.9 x 100 = 1690 cms.

Now we write down the proportion and solve for x

$\frac{4}{x}=\frac{34}{1690} \\x=\frac{4(1690)}{34} \\x=\frac{6760}{34}\\ x=198.82$

Therefore, the shortest side of piece will be 198.82 cm. (or 1.98 meters long)

8x+4y=-20 and -4x-8y=-20 solve each system by substitution

True [87]

8x + 4y = -20
4y = -20 - 8x
y = -5 -2x

-4x - 8y = -20
-4x - 8(-5-2x) = -20
-4x + 40 + 16x = -20
12x = -60
x = -5

8(-5) + 4y = -20
-40 + 4y = -20
4y = 20
y = 5

A right cylinder has a radius of 3 and a height of 12. What is its surface area?

shepuryov [24]

Answer:

Surface Area = 283

Step-by-step explanation:

Radius = 3

Height = 12

Formula for suface area is SA= 2πrh+2πr^2

let "r" be for radius

let "h" be for height

SA=2*π*3*12+2*π*3^2

SA=282.74

round to the nearest ones spot and that will make the surface area = 283
