Answer: 8 weeks

Step-by-step explanation:

Given : Stephen is tracking how many words per minute (wpm) he reads for reading class.

Equation: $w = 112 + 8t$ , where t = time (weeks) and w = wpm .

Then, the equation to find number of weeks (w), it will take Stephen to reach

171 wpm is given by :-

$171=112+8t\\\\\Rightarrow\ 8t=171-112\\\\\Rightarrow\ 8t=59\\\\\Rightarrow\ t=\dfrac{59}{8}=7.375\approx8$

Hence it will take about 8 weeks Stephen to reach 171 wpm.

PLEASEEEE HELPPP ITS DUE IN 15 MINUTES!! the exponential regression representing the population of Lazy Town as a function of ti

Advocard [28]

Given:

$R^2=0.92,a=8000,b=0.9$ .

Exponential regression model is

$y_1\sim a(b)^{x_1}$

To find:

The exponential regression representing the population of Lazy Town as a function of time in years.

Solution:

Exponential regression model is

$y_1\sim a(b)^{x_1}$ ...(i)

We have, $a=8000,b=0.9$ .

Substituting $a=8000$ and $b=0.9$ in (i), we get.

$y_1\sim 8000(0.9)^{x_1}$

Therefore, the exponential regression representing the population of Lazy Town as a function of time in years, is $y_1\sim 8000(0.9)^{x_1}$ .

Help pleaseee one of them is positive fractions and procedural fluency

navik [9.2K]

5) make the 5 a fraction (5/1) then use keep change flip to make the equation 5/1 * 10/3

That will give you 50/3, simplify that and you get 16 2/3

16 2/3 is your final answer

6) use keep change flip to make the equation 8/10 * 5/2

This will give you 40/20

Since 40 goes into twenty the answer is 2

2 is your final answer

Find the angles of the triangle, if the midpoint of one of its bisectors coincides with the midpoint of the segment connecting f

Mumz [18]

Answer:

all are 60°

Step-by-step explanation:

The midpoints of the angle bisector and the foot of the median will lie on the midsegment of the triangle. In order for the foot of the altitude to lie on that same midsegment, the altitude must be a median.

If the angle bisector intersects the midpoint of the midsegment, it, too, is a median. The angle bisector will be a median only if the triangle is isosceles with the bisector's angle being the a.pex. The altitude will be a median only if the altitude's vertex is the a.pex of an isosceles triangle. Hence, the triangle must be equilateral, and all angles are 60°.
