$- 0.25z = - 1.25 \\ \Leftrightarrow \: z = \frac{ - 1.25}{ - 0.25} = \frac{ - \frac{5}{4} }{ - \frac{1}{4} } = 5$

A juice stand sells smoothies in cone-shaped cups that are 8 in. tall. The regular size has a 4 in. diameter. The jumbo size has

nirvana33 [79]

All cone-shaped cups have the same height in 8 inches. They just differ in their diameters. To solve for the volume of the regular and jumbo sizes, let's use the formula for the volume of cone

V = (1/3)*pi*(r^2)*h

r is just the half of the diameter, h is the height which is equal to 8

Regular size:
V = (1/3)*pi*((4/2)^2)*8
V = 33.5 cube inches

Jumbo size:
V = (1/3)*pi*((8/2)^2)*8
V = 134.0 cube inches

Answer:

x = 6

Step-by-step explanation:

When 2 chords of a circle intersect then the product of the parts of one is equal to the product of the parts of the other, that is

2x = 3 × 4, that is

2x = 12 ( divide both sides by 2 )

x = 6
