The answer is 115 degrees because adding the two remote interior angles is the same as the one exterior angle .

Answer:

115 degrees

Step-by-step explanation:

first find the missing angle in the triangle

75+40+x=180

x+115=180

x=65

That angle plus the ? angle form a straight line, meaning they add up to 180 degrees.

so 65+x=180

x=115

Anusha is walking on a hiking trail at a rate of 3/4 miles in 1/4 hour. At this rate, how far will Anusha walk in an hour?
kherson [118]
3 miles. Using cross-multiplication, 3×4 = 12 and 4×1 = 4, so 12/4 = 3.

What is the abbreviation for SI unit of mass
Blababa [14]
I would go with either NIST or SIKG. I put SIKG because the abbreviation for mass is kg and you r look for the SI unit of mass and then the SI stands for International System of units. So when you put both SI And KG (kilograms=mass) it makes SIKG.


This is probably not right but I tried.

Good Luck!

It is estimated that t-weeks into a semester, the average amount of sleep a college math student gets per day S(t) decreases at
goldenfox [79]

Answer:

s(15)= \frac{-3}{2} e^{15^{2} } +9.6

Step-by-step explanation:

Before to getting started ,we have to consider the function which  represents  sleep decline rate S'(t) =-3te^{t^{2} } \\

Since  this function is interpreted in this case as a rate of change, we can deduce this funcion is the first derivative of the function of  average amount of sleep (S(t)).

In order to find S(t), we will integrate S'(t)

\int\limits^ {} -3t3e^{t^{2} } \, dx \\

This case corresponds to intergration by substitution  

Substituting u=x^{2} \\

Computting the differential of u

\frac{du}{dt} =2tdt\\

Now, let's go back to our integral and write it in terms of u, using both definition of u and its defferential.

\int\limits^{}-3te^{u}  \, \frac{1}{2t}du  \\\\\int\limits^{}\frac{-3}{2} e^{u}du\\

The integral  of a exponential function is itself. So the result is:

\frac{-3}{2} e^{u} +c

Now substitute u back in:

\frac{-3}{2} e^{t^{2} } +c

This answer correspond to function of average amount of sleep.

We know that when the semester begins (t=0) , math students sleep an average of 8.1 hours per day so we will use this info in order to find the value of c.

s(0)=\frac{-3}{2} e^{0^{2} } +c=8.1\\\\\frac{-3}{2} +c=8.1

Solve this equation

c=8.1+\frac{3}{2}

c=9.6

Replacing  the value of c on S(t)

S(t)= \frac{-3}{2} e^{t^{2} } +9.6

Now, let's to find the average of amount of sleep   when 15 weeks has elapsed since the start date of the semester.

s(15)= \frac{-3}{2} e^{15^{2} } +9.6

Luke is building a storage building and needs to have a slab of concrete poured. He knows the contractor charges an initial cost
kherson [118]
The answer is A.

 y is the total cost, than you would need to multiply x, the number additional number of square feet, which is 3.5x. you would then add 95 dollars to the equation to represent the initial fee. So the equation would look like Y=3.5x+95.
