Answer:
The answer to your question is 8 h
Step-by-step explanation:
Data
length of the ladder = 200 cm
distance between each rung = 20 cm
rate = 10 cm/h
fifth rung = ?
Process
1.- Calculate the total distance the tide must rise
distance = 20 cm x 4
= 80 cm because the first rung touches the water
2.- Calculate the time
rate = distance / time
-Solve for time
time = distance / rate
-Substitution
time = 80 cm / 10cm/h
-result
time = 8 h
Seventy that’s just simple math lol. Your welcome and hopes it helped
Answer:
Part A: Rewrite the expression by factoring out the greatest common factor. (4 points)
<em><u>answer</u></em><em><u>:</u></em>
<em><u>2</u></em><em><u>y</u></em><em><u>(</u></em><em><u>x³</u></em><em><u>+</u></em><em><u>4</u></em><em><u>x-2x²-8</u></em><em><u>)</u></em>
Part B: Factor the entire expression completely. Show the steps of your work. (6 points)
answer:
<em><u>2y(x³+4x-2x²-8)</u></em>
<em><u>2</u></em><em><u>y</u></em><em><u>(</u></em><em><u>x³-2x²</u></em><em><u>+</u></em><em><u>4</u></em><em><u>x</u></em><em><u>-</u></em><em><u>8</u></em><em><u>)</u></em>
<em><u>2</u></em><em><u>y</u></em><em><u>(</u></em><em><u>x²</u></em><em><u>(</u></em><em><u>x-2</u></em><em><u>)</u></em><em><u>+</u></em><em><u>4</u></em><em><u>(</u></em><em><u>x-2</u></em><em><u>)</u></em><em><u>)</u></em>
<em><u>2</u></em><em><u>y</u></em><em><u>(</u></em><em><u>x²</u></em><em><u>+</u></em><em><u>4</u></em><em><u>)</u></em><em><u>(</u></em><em><u>x-2</u></em><em><u>)</u></em>
Try getting rid of the decimal. then divide 225 by 5.
the answer will be 45 nickels
