Answer:
You know that XZ is 15 and the whole perimeter of the triangle is 50. WZ is going to be the same length as WX due to the lines saying that they are equal.
Your first step is to take 50-15=35, we did this because we already know the length of one side and can take that off from the whole.
The next step is to divide 35 by 2, because both sides are going to be the same length.
35/2=17.5
You final answer would be 17.5
Hope this helps ;)
Answer:
put it all in tiger algebra it will give you all of the answers
Step-by-step explanation:
T = 5.34 + 0.78m
T = 5.34 + 0.78 * 5
T = 5.34 + 3.9
T = 9.24
Tina was charged $9.24 at the car wash for 5 minutes.
Answer: b
explanation: CD=AB since they are parallel meaning 33 = x+14 (solve to get y=19) and then AD=CB because they are also parallel meaning y=10
Answer:
k ≈ 0.1733
Step-by-step explanation:
Using the numbers given, we find the multiplier of the population is 800/200 = 4 in 8 hours. This means the equation of growth can be written ...
y = 200(4^(t/8))
When this is written in the form ...
y = 200·e^(kt)
We can compare the two equations to see that ...
4^(1/8) = e^k
Taking natural logarithms, we have ...
1/8·ln(4) = k ≈ 0.1733
The growth rate k is approximately 0.1733.

<em>Additional comment</em>
The comparison we were looking for was (4^(1/8))^t = (e^k)^t. Instead of "comparing" the equations, you could set them equal and solve for k.
200(4^(t/8)) = 200e^(kt)
4^(t/8) = e^(kt) . . . divide by 200
t/8·ln(4) = kt·ln(e) . . . . take natural logs
1/8·ln(4) = k . . . . . . use ln(e) = 1 and divide by t
