Answer : y= 2x

When y is directly proportional to x then

y = kx where k is the constant of proportionality.

y = 2x , the value of k is 2. so 2 is the constant of proportionality.

y = x + 2, the equation is not in the form of y=kx

2y = x , y= \frac{x}{2} so constant of proportionality k is \frac{1}{2}

y + 2 = 2x , y = 2x -2 is not in the form of y=kx

You have an ice cream scoop with a 2-inch diameter. You have an ice cream cone with a 2-inch diameter and a height of 5 inches.
IRISSAK [1]

Answer:

Since the volume of the cone is bigger than the volume of the scoop, it won't spill.

Step-by-step explanation:

In order to calculate if the ice cream will spill we will need to calculate the volume on the ice cream scoop and the volume of the cone. If the volume of the scoop is bigger than the cone it will spill.

volume scoop = (4/3)*pi*r³ = (4/3)*pi*(2/2)³ = 4.1888 in³

volume cone = (pi*r²*h)/3 = [pi*(2/2)²*5]/3 = 5.236 in³

Since the volume of the cone is bigger than the volume of the scoop, it won't spill.

4 7/8 + 11 1/2 = 16 3/8
4 + 7/8 + 11 + 1/2
4 + 11 = 15
7/8 + 1/2 = 7/8 + 4/8 = 11/8
11/8 = 1 3/8
15 + 1 + 3/8 = 16 3/8

Can somebody please help me .
Lyrx [107]

Answer:

Both of theses are irrational.

Step-by-step explanation:

The reason is because when you try to find out how to get the square root of 2 you get a whole bunch of numbers, and the same thing happens when you try to find the square root of 8. in turn both of these numbers are irrational.
