Can someone plz help me with dis i will give brainliest
Reil [10]

Answer:

first one:  B and C

Second one: x=12, y=10 so the answer is B.

Step-by-step explanation:

First one: Irrational numbers are any numbers that go on forever in the decimal without ever repeating. Any square roots of numbers that aren't perfectly square, such as 4 and 9, are irrational. And anything with pi, or \pi, is always irrational.

Second one: 144 and 100 are perfect squares, meaning it can be created by multiplying the same number by itself, in this case 12 and 10. Subtract those and you get 2.

If the length of the side of a square is doubled, what is the ratio of the areas of the original square to the area of the new s
7nadin3 [17]

Answer:

\frac{1}{4}

Step-by-step explanation:

Let 's' be the side of the original square

the length of the side of a square is doubled, so the length of the new square is 2s

Area of the original square with side length 's' is s^2

Area of the new square with side length '2s' is (2s)^2=4s^2

Area of the new square is 4  times the area of the original square

ratio of the areas of the original square to the area of the new square

\frac{s^2}{4s^2} =\frac{1}{4}

Use the diagram of the right triangle above and round your answer to the nearest hundredth.
Yakvenalex [24]

Answer:

value of a = 6.93 m

hence , (b.)

Step-by-step explanation:

the given triangle is a right angled triangle, so

by using trigonometry.

=》

\tan(a)   = \tan(30)  =  \frac{1}{ \sqrt{3} }

and we know,

=》

\tan(a)  =  \frac{a}{b}

so, by above values of tan ( a ) we get,

=》

\frac{a}{b}  =  \frac{1}{ \sqrt{3} }

=》

\frac{a}{12}  =  \frac{1}{ \sqrt{3} }

=》

a = \frac{12}{ \sqrt{3} }

=》

a = 4 \sqrt{3}

=

=》

a = 6.93

hence, a = 6.93 m
