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)

What should the following equation be multiplied by to eliminate the decimals?6.74x-1.026=0.138.
Evgen [1.6K]

Answer:

b.1000

Step-by-step explanation:

6.74x-1.026=0.138

The smallest decimal goes to the thousandths place, so we need to multiply by 1000

.138

. tenths  hundredths  thousandths

Another way to look at it

.138 = 138/1000  so multiply by 1000 to get rid of the decimal

1.026 is to the same place value so we could pick either one to determine what to multiply by
