Answer:

D. reflection across a vertical line

Step-by-step explanation:

Reflection is basically a mirror image. Since you can see that the first triangle is flipped over to get the second one, this is a reflection.

It is not a vertical translation; this means that the triangle shifted up or down.

It is not a horizontal translation, this means that the triangle shifted left or right.

It is not a rotation about point A either, this would have meant that the triangle spun around.

5/6 is not the definite ratio, when you take a larger sample size it could be off by a bit like 499/600 or 501/600

Please Geniuses, look at the picture and answer me, RESCUE ME.

Answer:

1. $\{ \bold{ \sf{Expenditure \: on \: food = \:1200 dollars\: }}$

2. $\sf{a \: : \: c \: = 18 \: : \: 5}$

Step-by-step explanation:

1. $\sf{here \: total \: expenditure = 3000 \: dollars}$

$\sf{expenditure \: on \: food \: = \: \frac{3000}{360} \times 144}$

$\sf{expenditure \: on \: food{ = 1200 \: dollars}}$

Note : Whole circle represents the total expenditure.

i.e 360° represents $ 3000

1° represents $ $\sf{ \frac{3000}{360} }$

144 ° represents $ $\sf{ \frac{3000}{360} \times 144}$

-------------------------------------------------------------

2. $\sf{here \: a:b \: = 6:5 \: = \: \frac{6}{5} }$

$\sf{b : \: c \ \: = 18 \: : \: 6} \: = \: \frac{18}{6}$

$\sf{now \: a:b \times b:c = \frac{a}{b} \times \frac{b}{c} = \frac{a}{c} }$

⇒ $\sf{a:c = \frac{6}{5} \times \frac{18}{6} }$

⇒ $\sf{a:c = \frac{18}{5} }$

⇒ $\sf{a:c = 18:5}$

Hope I helped!

Answer:

$\frac{1}{3}$ is a rational number as as it can be written in the form $\frac{p}{q}$ where p and q are integers and q ≠ 0. It is also a real number as the set of real number consists of all the natural numbers, whole number, rational number, integers, and irrational number.

Step-by-step explanation:

As we know that any number that can be written in the form $\frac{p}{q}$ is said to be a rational number.

Thus, $\frac{1}{3}$ is a rational number as it can be written in the form $\frac{p}{q}$ where p and q are integers and q ≠ 0.

It is not a natural number as the set of natural number is:

$N\:=\:\left\{\:1,\:2,\:3,\:...\right\}$

It is also not a whole number as the set of whole number is:

$W\:=\:\left\{0,\:1,\:2,\:3,\:...\right\}$

It does also not a belong to integer number as the set of integers is:

$Z=\:\left\{...-3,\:-2,\:-1,\:0,\:1,\:2,\:3,\:...\right\}$

It does also not a irrational number as the irrational numbers are those which can not be written in the form $\frac{p}{q}$ .

BUT

It belongs to the set of real number.

The real numbers include natural numbers or counting numbers
whole numbers
integers
rational numbers
and irrational numbers.

Therefore, from the above discussion we can conclude that $\frac{1}{3}$ is a rational number as as it can be written in the form $\frac{p}{q}$ where p and q are integers and q ≠ 0. It is also a real number as the set of real number consists of all the natural numbers, whole number, rational number, integers, and irrational number.
