How do u convert a fraction into a decimal

1 answer:

3 0

You have to divide the numerator (top number) by the denominator (bottom number). For example, 1/2 is 0.5
However, some end up as never-ending decimals, like 1/3, which converts to 0.333 repeating.

Enter the equation of the line in slope-intercept form.

likoan [24]

Equation parallel to y = -x is y=-x+k

so 4.5 = -7 + k so k - 11.5

Equation is y = -x + 11.5

Determine whether the polygons to the right are similar. If so, write a similarity statement and give the scale factor. If not

Tamiku [17]

Answer:

(a) Similar polygons; scale factor is 2

(b) Similar polygons; scale factor is 1.5

Step-by-step explanation:

Given

See attachment for polygons

Required

Determine if they are similar or not

Solving (a): The triangle

The angles in both triangles show that the triangles are similar

To calculate the scale factor (k), we simply take corresponding sides.

i.e.

$k = \frac{DF}{BA} = \frac{FE}{AC} = \frac{DE}{BC}$

$k = \frac{6}{3} = \frac{8}{4} = \frac{10}{5}$

$k = 2=2=2$

$k = 2$

The scale factor is 2

Solving (b): The trapezium

The angles in both trapeziums show that the trapeziums are similar

To calculate the scale factor (k), we simply take corresponding sides.

i.e.

$k = \frac{KN}{GJ}$

$k = \frac{6}{4}$

$k = 1.5$

The scale factor is 1.5

At a gathering of 15 people, there are 10 people who all know each other and 5 people who know no one. People who do not know ea

melomori [17]

Answer:

Each one of the ten people has to shake hands with all the $20$ other people they don’t know. So $10\cdot20 = 200$. From there, we calculate how many handshakes occurred between the people who don’t know each other. This is simply counting how many ways to choose two people to shake hands from $10$, or $\binom{10}{2} = 45$. Thus the answer is $200 + 45 = \boxed{\textbf{(B)}\ 245}$.
