The correct answer to this question is false.

The number 0.8 can in fact be written as 8/10 (because when you divide 8/10 you get 0.8 so they are equivalent values); however, rational numbers are those that can be written as a fraction (the division of two numbers). Irrational numbers are numbers that cannot be expressed in fractional form. This means that 8/10 is not irrational, it is rational, because you can express it in fractional form. This means your answer is false.

Hope this helps!

A web music store offers two versions of a popular song. The size of the standard version is 2.3 megabytes (MB). The size of the
Effectus [21]

answer

240 standard versions

set up equations

s = number of standard versions

h = number of high quality versions

the total size of all standard versions would be 2.3s since each standard version is 2.3 MB

the total size of all high quality versions would be 4.4h since each standard version is 4.4 MB

add them together to get the total size (2664 MB) of all versions

2664 = 2.3s + 4.4h

since the high quality version was downloaded twice as often as the standard, we can say that

h = 2s

substitute h into equation and solve

2664 = 2.3s + 4.4h

h = 2s

2664 = 2.3s + 4.4(2s)

2664 = 2.3s + 8.8s

2664 = 11.1s

s = 2664/11.1

s = 240

Triangles are similar. Round answer to nearest tenth (step by step)
ozzi

Answer:

13.5

Step-by-step explanation:

Similar = alike but not the same

A lot of times in geometry it would mean that they have the same shape, just different size, so first find the ratio:

6/12 = 1/2

27 * 1/2 = 27/2 = 13.5
