9*9*8*7
You can choose 9 digits for the first digit, 9 Fót the second (because IT can be 0) and 8 Fót the third etc.. hope this helps
It would take 36 minutes. If you use unit rate, you would take 20min/5people and see how many minutes does it take to paint one wall. Which would be represented by 4min/1person. To find how many minutes it would take for 9 walls, you get 4min/1person to become 9 people for the denominator. Then, whatever you do to the denominator you do to the numerator. So, 4 times 9 is 36. Therefore, making the answer 36minutes/9people.
It is irrational, as it's not a number that can be divided into a whole number by another whole number.
Answer: Part A: No; Part B; N/A
Step-by-step explanation:
The two triangles are not congruent because it's SSA, which doesn't work unless it's a right triangle.
Given that <span>Line WX is congruent to Line XY and Line XZ bisects Angle WXY.
We prove that triangle WXZ is congruent to triangle YXZ as follows:
