Answer:
{a,b,c,d,f,3,4,5,7}
Step-by-step explanation:
If X={a,b,c,3,4,5}
Y={b,d,f,3,5,7}
THEREFORE {XUY}= {a,b,c,d,f,3,4,5,7}
XUY represents the union of sets X and Yas {a, b, c, d, f, 3, 4, 5, 7}.
What is a set?A set is defined as a group of objects in mathematics. Set names and symbols begin with a capital letter. According to set theory, a set's constituent parts can be included in anything.
The sets are given in the question, as follows:
X = {a,b,c,3,4,5}
Y = {b,d,f,3,5,7}
We have to determine the members of the set XUY, using set braces.
As per the question, the required solution would be as:
XUY = {a, b, c, d, f, 3, 4, 5, 7}
XUY represents the union of sets X and Y, which contains all elements that are in set X or set Y, or in both. Since none of the elements in set X or set Y are repeated, all of the elements in set X and set Y are included in the union without duplication.

The formula of area for triangles: [tex]\frac{1}{2}bh[/tex]
[tex]\frac{1}{2}[/tex] * 7 = 3.5 (3.5 *2) = 7
The formula for area of a rectangle: bh
7*3 = 21
Add the areas together 21+7 = 28 squared cm
Answer:
28cm²
Formula of area of triangle:
1/2 x base x height
Formula of area of rectangle:
length x width
thus,
area of the whole thing:
(1/2 x 7cm x 2cm)+(3cm x 7cm)
=7cm²+21cm²
=28cm²

find the angle of elevation of a kite on a 50m
string flying 40m vertically above the ground.
The angle of elevation of a kite is 53.13°
What is angle of elevation?"It is the angle formed by the line of sight and the horizontal plane for an object above the horizontal surface."
What is sine angle?"For a right triangle, the sine of acute angle [tex]\theta[/tex] is,
[tex]sin(\theta)=\frac{opposite ~side}{hypotenuse}[/tex]"
For given question,
Consider the following diagram for given question.
The length of the string (AC) = 50m
The kite is flying 40m vertically above the ground.
⇒AB = 40m
We need to find the angle of elevation [tex]\theta[/tex]
Consider the sine of angle [tex]\theta[/tex]
[tex]\Rightarrow sin(\theta)=\frac{AB}{AC} \\\\\Rightarrow sin(\theta)=\frac{40}{50}\\\\\Rightarrow sin(\theta)=0.8\\\\\Rightarrow \theta=sin^{-1}(0.8)\\\\\Rightarrow \theta=53.13^{\circ}[/tex]
Therefore, the angle of elevation of a kite is 53.13°

The graph represents distance traveled varying directly with time.
What would be the distance traveled after 12 hours?
a. 40 miles
b. 540 miles
c. 480 miles
d. 600 miles
Answer:
c. 480 miles.
Step-by-step explanation:
From the graph:
after 5 hours distance travelled is 200 miles.
So by proportion distance in 12 hours = 200 * 12/ 5
= 2400/5
= 480 miles.

how can you tell two objects are similar when all you did is make the the object smaller by a scaled factor?
if good answer... will give brainly and also 5 stars and everything
Answer:
You can tell if they are similar if all the angles correspond and the sides are all scaled down by the same factor. For instance, a triangle with sides of 30, 40, and 50 scaled down by a factor of 2 would have sides of 15, 20, and 25.
