Answer:
B. The ratio of the area of the scale drawing to the area of the painting is 1:16
C. The ratio of the perimeter of the scale drawing to the perimeter of the painting is 1:4
Step-by-step explanation:
The ratio of the area of similar figures/shapes = the square of the ratio of any of their side lengths
Since the scale drawing of the rectangular painting and the actual rectangular painting are similar, therefore,
The ratio of the area of the scale drawing to the painting = 1²:4²
= 1:16
Also, comparing the ratio of the perimeter of the scale drawing to the perimeter of the painting will be the same as the scale factor = 1:4

Yes it proportional because they all function of y=3x
0x3=0
2x3=6
4x3=12
6x3=18
I think it’s 7 Becuase the Ae and DE are congruent
Answer:
Step-by-step explanation:
<u>Given number:</u>
29,980,000,000
<u>Rules:</u>
- Move the decimal point after the first non-zero digit. (after 2)
- Here, we will move the decimal point 10 places to the left to move it after the first non-zero digit.
- Since we move the decimal point 10 places, we will write the number as a multiple of 10¹⁰ (10 being the exponent).
<u>The number will become:</u>
2.998 × 10¹⁰
