If d = m/v, what is the equation when solved for v? **please explain**
inn [45]
V= m/d.  When you get questions asking about density/mass/volume draw a triangle just like in the picture i have attached and with your finger cover up the one you are looking for. So to find the equation for volume you cover up volume and you are left with mass divided by density.

If x &gt; 0 and y &gt; 0, where is the<br> point (x, y) located?
Scrat [10]
  • Given, x > 0, y > 0.
  • So, the values of x and y are less than 0, that means, they are negative integers.
  • If we divide a Cartesian plane with the x-axis and y-axis, we get four quadrants.
  • 1st Quadrant : (+,+)
  • 2nd Quadrant : (-,+)
  • 3rd Quadrant : (-,-)
  • 4th Quadrant : (+,-)
  • Since the values of x and y are both negative, so (x, y) is located in the <em><u>3rd Quadrant</u></em>.

Hope you could get an idea from here.

line segment ab has a slope 5/4 and contains point a(8,-7). what is the y-coordinate of point q(3,y) if qa is perpendicular to l
MArishka [77]
U have a slope of 5/4...a perpendicular line will have a negative reciprocal slope...which means, the slope we need is -4/5.

Now we use y = mx + b
slope(m) = -4/5
(8,-7)
-7 = -4/5(8) + b
-7 = -32/5 + b
-7 + 32/5 = b
-35/5 + 32/5 = b
-3/5 = b

equation is : y = -4/5x - 3/5.....4x + 5y = -3

4x + 5y = -3....when x = 3
4(3) + 5y = -3
12 + 5y = -3
5y = -3-12
5y = - 15
y = -15/5
y = - 3 <===

The high temperatures in Anchorage, Alaska for five days in December were -8°C, -1°C, 2°C, 4°C, and -2°C.
IRISSAK [1]

Answer:

-1 Degree C

Step-by-step explanation:

When its talking about average temperature, its talking about the mean. To calculate mean, you add all the numbers and divide it by how many numbers are there.

(-8) + (-1) + 2 + 4 + (-2) = -5

mean = -5/5

-1 degree C
