Answer:

Step-by-step explanation:

To think about this logically, lets take a different, more simplified example.

Lets say we have two numbers: 4 and 6

The product of these numbers is 24. If we doubled the product, we would get 48.

Using our original equation, how could we get a result of 48? We could double either 4, or 6. 8 times 6 equals 48, and 12 times 4 equals 48.

So, from this we can take away that in an expression, doubling one number will double the answer. On a side note, you could you use this not only when doubling a number. If you tripled a number in an expression, then the answer to the expression would also triple.

So, the answer to your question is (A) - Double one dimension

Answer:

OPTION A

Step-by-step explanation:

AS IF SHE DOUBLES 1 DIMENSION THE VOLUME BECOMES TWICE.

V=L*B*H

IF L IS DOUBLED ..

THEREFORE,NEW VOLUME=

V2=2L*B*H

V2=2 L*B*H

A scoop of ice cream is the shape of a whole perfect sphere sits in a right cone.
Andrei [34K]

Answer:

  10 cm

Step-by-step explanation:

The volume of a sphere is given by the formula ...

  V = 4/3πr³

The volume of a cone is given by the formula ...

  V = 1/3πr²h

The ratio of the volume of the cone to that of the sphere is ...

  Vcone/Vsphere = (1/3πr²h)/(4/3πr³) = h/(4r)

In order for the ratio to have a value of 1, we must have ...

  h = 4r

The height of the cone must be 4×2.5 cm = 10 cm to fit all of the ice cream.

Determine if the following lengths could represent a triangle. If they can, determine if the triangle, is acute, obtuse, or righ
stiks02 [169]

9514 1404 393

Answer:

  A. no

  B. no

  C. obtuse

Step-by-step explanation:

For side lengths to form a triangle, the sum of the shorter two must exceed the longest.

A. 5 + 8 = 13 . . . . a line segment, not a triangle

B. 7 + 12 < 26 . . . . no closure, not a triangle

C. 11 + 15 > 20 . . . . a triangle. A picture shows it to be obtuse

  You can also compare 11² +15² vs 20² ⇒ 346 vs 400. The long side is too long for a right triangle, so the triangle must be obtuse. (The Pythagorean theorem tells you a right triangle with those legs would have a long side of √346 = 18.6.)
