Answer:
1 ,3,4
Step-by-step explanation:
29,032,000,000 is twenty nine billion thirty two million in standard form.
Answer:
495 feet
Step-by-step explanation:
tan22° = 200/d
so, d = 200/tan22°
Then, d = 495.0173707 => 495 feet to the nearest foot

The <em><u>correct answers</u></em> are:
3/2 - expansion; 1/4 - contraction; 4 - expansion; 0.8 - contraction; -3 - expansion.
Explanation:
A scale factor larger than 1 would be an expansion. The factors we have listed that are larger than 1 are 3/2 and 4.
A scale factor between 0 and 1 would be a contraction. The factors we have listed that are between 0 and 1 are 0.8 and 1/4.
A negative scale factor will result in a larger, inverted figure. This means the scale factor of -3 will be an expansion.
The area of triangle DEF is 2137.5 cm²
Solution:
Given data:
Area of ABC = 38 cm²
Scale factor = 7.5
To find the area of DEF:
<em>Area of dilated image = Area of original image × (scale factor)²</em>
Area of DEF = 38 × (7.5)²
= 2137.5 cm²
Area of DEF = 2137.5 cm²
The area of triangle DEF is 2137.5 cm²
