$\text{Look at the picture}$

$\text{The slope:}\ m=\dfrac{\Delta y}{\Delta x}\\\\\Delta y=3,\ \Delta x=1\\\\m=\dfrac{3}{1}=3$

$\text{The point-slope formula:}\ y-y_1=m(x-x_1)$

$(1,\ 5)\to x_1=1,\ y_1=5\\\\y-5=3(x-1)\to\boxed{Answer:\ 4.}$

If 160 is divided by x, then the remainder is 4. What is the remainder when 315 is divided by x?

frutty [35]

Let us rewrite this equation as:
160/x = some number + 4/x
we can assume that some number of x's can fit into 160, but x is greater than 4 so we have a remainder.
We can figure out by using the remainder that x is completely divisible into (160-4) or 156. Knowing this we can assume that x is some factor of 156 that is greater than 4.
Let us list the factors of 156
1,2,3,4,6,12,13,26,39,52,78,156
Now let us refer back to the restrictions we put on x.
x must be > 4 as anything less than 4 would divide at least 1 more time into it. So now we are left with a bunch of other factors. And the cool thing is that all of the factors excluding anything that is = or < 4 all work for getting a remainder of 4. Thus we can use the largest factor and set it equal to x.
So x = 156
then if we divide 315 by x or 315/x = 315/156 = 2 and a remainder of 3
so the answer would be 3.

23 20' 48" is the same as _____. Round to the nearest hundredth of a degree.

pentagon [3]

23° 20' 48" in degrees

Minutes are 1/60 of a degree and seconds 1/60 of a minute.

Let's convert the 48" to minutes.
48/60 = 0.8

23° 20' 48" ⇒ 23° 20.8'

Let's convert the 20.8' to degrees.
20.8/60 ≈ 0.3466667

23° 20.8' ⇒ 23.35°

Find the coordinates of the midpoint of a segment with the endpoints (7,−5) and (3,3).

aksik [14]

Answer:

(5, -1)

Step-by-step explanation:

Midpoint = (x1 + x2 ÷ 2) , (y1 + y2 ÷ 2)

MP= (7 + 3 ÷ 2), (-5 + 3 ÷ 2)

= (10÷2), (-2÷2)

=(5), (-1)
