I would agree with A. Copying a segment.

Hope this helps you.

I believe it would be A. copying a segment, because with a parallel line the lines will not be intersecting, and copying the segment would be the only answer to give you lines that don't intersect.

Xelga [282]

Answer:

8 ft²

Step-by-step explanation:

Given 2 similar triangles with ratio of sides = a : b, then

ratio of areas = a² : b²

Here the ratio of sides = 2 : 3, thus

ratio of areas = 2² : 3² = 4 : 9

let x be the area of Δ EFG, then by proportion

$\frac{4}{x}$ = $\frac{9}{18}$ ( cross- multiply )

9x = 18 × 4 = 72 ( divide both sides by 9 )

x = 8

The area of Δ EFG is 8 ft²

How many ways are there to rearrange the letters ALIVE in such a way that the word EVIL is not contained in the resulting word

Sergio [31]

Answer: 118 combinations.

Step-by-step explanation:

In ALIVE we have 5 letters, rearranging it we have the possible options of:

5 options for the first letter.

4 options for the second letter, as one was already chosen for the first one

3 options for the third letter, as 2 were already chosen.

2 options for the fourth letter.

1 option for the last letter.

The total number of combinations will be equal to the product of the numbers of options for each letter, then we have:

5*4*3*2*1 = 120 combinations.

And the combinations where the word EVIL is formed are:

AEVIL

EVILA

2 combinations, then the total number of combinations such that the word evil is not formed are:

120 - 2 = 118 combinations.

Please HELP. ALSO WHY. 2 question. pLZZ

avanturin [10]

Answer:

1). Number of kids on the other side = 16

2). Brian took the time to each piece of pie = 20 seconds

Step-by-step explanation:

1). Let the number of kids on one side = x

Then the number of kids on other side = 2x

3 adults helped the side having number of kids = x, then the number of people on this side = x + 3

Since the total number of people on this side = 11

Then the equation will be,

x + 3 = 11

x = 11 - 3

x = 8

Then number of kids on the other side = 2x = 2×8

= 16

2). By unitary method,

∵ Brian took the time to eat 6 pieces of the pie = 2 minutes

∴ Brian will take time to eat 1 piece of pie = $\frac{2}{6}$ minutes

= $\frac{2}{6}\times 60$ seconds

= 20 seconds
