Answer and Step-by-step explanation: I would say 28 sized ladder with 29 extended length and 31'5 Max reach
Hii :)
<em>Lets solve for </em><em>x</em><em> (x being what time jake will leave)</em>
<em>First, what do we know?</em>
<em> </em>
<em> We know..</em>
- <em>Needs to arrive by 2:20pm</em>
- <em>53 minutes to get there</em>
<em>2:30-53=1:37</em>
<em>So jake should leave around 1:00pm-1:30pm</em>
<em />
<em>2:30-1:30=1:00</em>
<em>Hope this helps</em>
Answer:
Step-by-step explanation:
The formula you will need for this is:
where A is the amount after some decay has happened, A₀ is the intial amount, t is the time in hours, and H is the half-life in hours. Those values for us are:
A = 2 g
A₀ = 25 g
H = 4.95 hrs and
t = ?
Filling in:
Keep in mind that, because of the nature of the exponential form of this equation, you CANNOT simply multiply the 25 by the 1/2. Exponential equations don't work that way. Begin instead by dividing both sides by 25 to get
The goal is to get that t out from its exponential position. Do that by taking the natural log of both sides:
After you take the natural log of the right side, the property allows you to bring the exponent down out front:
Now divide both sides by ln(.5) to get
Simplify the left side out on your calculator to get
and then divide:
Finally, multiply both sides by 4.95 to get
3.643856(4.95) = t so
t = 18.0 hours which is choice C
To find the value of x, use the vertical angle theorem.
Vertical angles are congruent.
Thus we have:
6x - 10 = 5x + 1
Solve for x.
6x - 10 = 5x + 1
Add 10 to both sides:
6x - 10 + 10 = 5x + 1 + 10
6x = 5x + 11
Subtract 5x from both sides:
6x - 5x = 5x - 5x + 11
x = 11
To find the value of y, use corresponding angles thoerem.
When two parallel lines are crossed by a transversal, the angles in matching corners are correponding angles.
Corresponding angles are congruent.
Thus, we have:
y = 6x - 10
Substitiute x for 11:
y = 6(11) - 10
y = 66 - 10
y = 56°
ANSWER:
x = 11, y = 56°
