Question:
Yan is climbing down a ladder. Each time he descends 4 rungs on the ladder, he stopped to see how much farther he has to go. If Yan made eight stops with no extra steps, which expression best shows another way to write the product of the number of ladder rungs that Yan and climbed?
4+4+4+4
8+8+8+8
(-1)(4+4+4+4)
(-8) + (-8) + (-8) + (-8)
Answer:
Step-by-step explanation:
Given
<em></em>
<em> --- It is negative because he is climbing down</em>

Required
An expression for the number of rungs climbed
To do this, we simply multiply the number of rungs by the steps taken.


This can be rewritten as:

The product, when written as sum is:
Answer:
2x+58+x=180 180-58=3x 122=3x
Step-by-step explanation:
x=40.666
*the sum of the angles of the triangle is 180 degrees
A. 1 out of 60 for the tv, 1 out of 25 for the video. This comes to 2/85 that one is faulty.
B. 286, since 285 has exactly a .95 chance
Answer:
C. 141.3
Step-by-step explanation:
The formula is pi times the radius squared (A = π r²).
So it might be 78.53
