Answer:   159.2\ cm^3

Step-by-step explanation:

The volume of cone is given by :-

\text{Volume}=\frac{1}{3}\pi r^2h

Given: The diameter of paper cups = 8 cm

Thus, the radius of paper cup (r)=\frac{8}{2}=4\ cm

The height of paper cup (h)= 9.5 cm

Now, the volume of paper cup will be :-

\text{Volume}=\frac{1}{3}\pi (4)^2(9.5)\\\\\Rightarrow\text{Volume}=\frac{1}{3}(3.14159265359)\times(16)(9.5)=159.174027782\approx159.3\ cm^3

Hence, the  best approximation for the volume of the paper cup 159.2\ cm^3

Oatmeal is made by mixing 15 cups of hot water to 6 cups of oats.
skad [1K]

9514 1404 393

Answer:

  • 2/5 cups oats per cup water
  • 2.5 cups water per cup oats

Step-by-step explanation:

The denominator of the fraction is the unit you want 1 of.

  (6 cups oats)/(15 cups water) = (6/15) cups oats/(1 cup water)

  = (2/5 cups oats)/(1 cup water)

1 cup of water would need 2/5 cups of oats.

__

Obviously, the other ratio is the reciprocal of this.

  (1 cup water)/(2/5 cups oats) = (5/2 cups water)/(1 cup oats)

1 cup of oats would need 2.5 cups of water

The slope of a line is 5, and you know it goes through the point (6, 2). Another point on the line goes through the y-coordinate
grigory [225]
Y = mx + b
slope(m) = 5
(6,2)...x = 6 and y = 2
sub and find b, the y int
2 = 5(6) + b
2 = 30 + b
2 - 30 = b
-28 = b
so the equation for this line is : y = 5x - 28

y = 5x - 28.......when y = -3
-3 = 5x - 28
-3 + 28 = 5x
25 = 5x
25/5 = x
5 = x <==== ur x coordinate
