The doorstop is a triangular prism. volume of the triangular prism is the area of the base times the height
area of the base: 1/2 * 10*6=30cm²
height: 2.5cm
Volume: 30cm²*2.5cm=75cm³
weight: 75cm³*8.6g/cm³=645 grams
Answer:
The exponent is negative
The exponent represents the number of places the decimal moves
The decimal moves to the right
Step-by-step explanation:
There are two prime numbers between 20 and 30: 23 and 29.
To find the percentage each number is of 125, you’d divide the number by 125 and move the decimal in the answer 2 places to the right to turn it to percentage notation (from decimal notation), so you’d solve 23/125 and 29/125.
23/125= .184
Moving the decimal two places to the right makes this 18.4%
29/125= .232
Moving the decimal two places to the right makes this 23.2%
X has two possible values of which you are to pick/use only one: 18.4 and 23.2
All sides are congruent
