expand using the distributive property of multiplication
Answer:20 pints of blue paint and 8 pints of yellow paint
Step-by-step explanation:
5 pints of blue and 2 pints of yellow make 7 pints of green. (5 + 2 = 7)You must do this four times to get 28 pints of green. (4 · 7 = 28)So you need 20 (4 · 5) pints of blue and 8 (4 · 2) pints of yellow.
Formula for volume:
πr^2(h/3)
Diameter divided by 2 is the radius
18/2 = 9
radius: 9 units
Use pythagorean theorem to find height
x^2 + 9^2 = 15^2
225 - 81 = 144
x^2 = 144
x = 12
height: 12 units
Plug these number in the volume formula.
Thus, it should be looking as:
π9^2(12/3) = 1017.88
Answer:
1017.88 
Answer:
-0.8 or -4/5
Step-by-step explanation:
You could do this a couple of ways. If you wanted to change your equation into slope-intercept form to make it easier for you, then you can do as follows:
4x + 5y = 10
5y = -4x + 10
y = -4/5x + 2
So your slope is -4/5.
Or you could do -A/B when your equation is in standard form. A is the term in front of the x value and B is the term in front of the y. Both strategies give you -4/5 for the slope.
