triangle PQR?

Select one:
1) 24 cm, 28 cm, 44 cm
2) 3 cm, 5 cm, 9 cm
3) 7 cm, 8 cm, 12cm
4) 24 cm, 21 cm, 33 cm

Answers

Answer: the correct answer is 3

The side lengths similar to triangle PQR are 24 cm, 28 cm, 44 cm

What are similar triangles?

Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles.

Given that, a triangle PQR with side lengths 6 cm, 7 cm, and 11 cm.

Considering option 1) 24 cm, 28 cm, 44 cm

To see the similarity, we will check if the ratio of the corresponding sides are equal or not,

6/24 = 1/4

7/28 = 1/4

11/44 = 1/4

That means, 6/24 = 7/28 = 11/44 = 1/4

Since, the corresponding sides of these triangles are in equal ratios,

Hence, The side lengths similar to triangle PQR are 24 cm, 28 cm, 44 cm

Step-by-step explanation:

The area of the triangle is

We need to convert the units to match

2 ft= 24 inches

A = 1/2 ( 24*6)

A = 1/2 (144)

A =72 in^2

When dilated 6 inches *4 = 24 inches

                      24 inches *4 = 96 inches

C.) 1

Step-by-step explanation:

EDG 2020

The value of f(g(0)) is 1.

What is Composition of Functions?

Composition of two functions f and g can be defined as the operation of composition such that we get a third function h where h(x) = (f o g) (x).

h(x) is called the composite function.

Given a table which shows values for the two functions f and g for different values of x.

We have to find the value of f(g(0)).

f(g(0)) = f[ g(0)]

From the table, g(0) = -1.

f(g(0)) = f(-1) = 1

Hence the value of f(g(0)) is 1.

The opposite of the number is -6 and its absolute value is 6.

We have a number -  6.

We have to find out the opposite and the absolute value of the number.

What is the Opposite and Absolute value of a number.

For a number - 'n', its opposite is '- n' and the absolute value of a number - 'n' is -

[tex]$n=\left \{ {{n} \;\;\;for \;n > 0\atop {-n}\;\;\;for\;n < 0} \right.[/tex]
