Colin’s piano lesson is 45 minutes, or Three-fourths of an hour, long. If he practices 6 different songs and spends an equal amo
NikAS [45]

Answer:

<em>Colin spends 1/8 of an hour practicing each song</em>

Step-by-step explanation:

Colin's piano lesson is 3/4 of an hour, long.

In that period, he practices 6 different songs, spending an equal amount of time on each one.

This means that each song gets the sixth part of the lesson duration. The fraction that expresses that amount is:

\displaystyle \frac{\frac{3}{4}}{6}=\frac{3}{24}=\frac{1}{8}

Colin spends 1/8 of an hour practicing each song

HELP PLEASE I NEED THIS DONE ASAP

a). 0.45 with a line over the 45 means 0.45454545454545... forever.

It's equivalent to  45/99  which is  <em>5/11</em> .

b). 0.45 with a line over the 5 means 0.455555555... forever.

It's equivalent to (0.4 + 0.555555.../10)

The 0.4 part is  4/10

The 0.5555555555.../10 part is  5/90 .

(4/10) + (5/90) = <em>41/90 </em>

c). 0.45 means 45/100 .  That's <em> 9/20</em> .

I don't think you're supposed to be posting unit test questions on Brainly.

50 students were asked what they did last night. 16 said they read a book, 41 said they watched TV, 7 said they did neither, how
Kamila [148]

Answer:

14 students

Step-by-step explanation:

Given

Let:

b \to read a book

t \to watched TV

So, we have:

n = 50 -- total

b = 16

t = 41

none = 7

Required

Students that did both (x)

This is calculated using:

Total = Books\ only + TV\ only + Both + None

So, we have:

n = (b - x) + (t - x) + x + none

This gives:

50 = (16 - x) + (41 - x) + x + 7

Open brackets

50 = 16 - x + 41 - x + x + 7

50 = 16 - x + 41 +7

Collect like terms

x = 16 - 50 + 41 +7

x = 14

<em>Hence, 14 students did both</em>

Answer: three dimensional figure and plane.

Step-by-step explanation:

A cross section is the intersection between a (three dimensional figure) and also a (plane).

When an object is being cut straight, the shape that we get is referred to as the cross section. We should note that several parallel cross sections will be firmed when we cut a particular object into slices.
