Answer:

7 cuts

Step-by-step explanation:

A net of a cube looks like the image below.

It has 5 edges connected to each other; two to the side, three in the middle.

That means that 12 - 5 = 7 cuts have to be made.

if the breadth of rectangle in one third of its length and perimeter is 80 cm find length and breadth of rectangle

LiRa [457]

Answer:

length = 30 cm

Breadth = 10 cm

Step-by-step explanation:

Length = x cm

Breadth = (1/3)x

Perimeter = 80 cm

2(length + breadth) = 80

2* (x + (1/3)x) = 80

$2*(\frac{3}{3}x+\frac{1}{3}x) = 80\\\\2*(\frac{4}{3}x) = 80\\\\\frac{8}{3}x = 80\\\\x = 80*\frac{3}{8}\\\\x = 10*3$

x = 30cm

length = 30 cm

breadth = $\frac{1}{3}*30=10$ cm

Nina had 3 friends ate lunch at a cafe they decided to split the bill evenly the total bill was 17.34 how much was each person s

Yuki888 [10]

Each person's share was $<span>5.78. All you had to do was divide the bill (17.34) by the number of people (3.) Hope this helps.</span>

Determine whether the geometric series is convergent or divergent. 10 − 6 + 3.6 − 2.16 + convergent divergent Correct: Your answ

Misha Larkins [42]

Answer:

The series CONVERGES with the sum being 6.25.

Step-by-step explanation:

Given that the geometric series is 10 - 6 + 3.6 - 2.16 + ....

So the first term of the geometric progression is, $a_{1}$ = 10

The second term of the geometric progression is $a_2$ = -6 = $a_1$ × r = 10 × r

where r is the constant ratio.

Therefore r = $\frac{-6}{10}$ = -0.6

The third term of the geometric progression, $a_3$ = 3.6 = $a_2$ × r = -6 × -0.6 = 3.6

The fourth term of the geometric progression, $a_4$ = -2.16 = $a_3$ × r = 3.6 × -0.6 = -2.16

So the above confirms that the series is indeed a geometric progression with first term, $a_{1}$ = 10 and constant ratio, r = -0.6

Now to find if the series converges or diverges we can take sum of the series from first term to infinity.

We can already infer that the series is convergent since the constant ratio, r = -0.6 which is less than 1.

So from the formula for the sum to infinity of a geometric progression, S, we get

S = $\frac{a_1}{1 - r} = \frac{10}{1 - (-0.6)} = \frac{10}{1 + 0.6} = \frac{10}{1.6} = 6.25$

So the series is convergent with the sum being 6.25
