Domain – All of the values that go into a relation or a function are called the domain. Range – All of the entities (output) which emerge from a relation or a function are called the range. All input values that are used (independent values) forms the Domain set.
Twenty is 40% of 50 because 10% of 50 is 5 so 5*4 = 20
Answer:
first triangle (to left) b=8, second one c=17
Step-by-step explanation:
for the first triangle (one to the left) the hypotenuse is 9, so let's use the pythagorean formula.
A^2 + B^2 = C^2
^ ^ ^
^ ^ Hypotenuse
^ second side
first side
Substitute:
5^2 + b^2 = 9^2
SImplify:
25+b^2 = 81
Reduce:
b^2 = 64
Simplify:
b=8
In the second triangle, we are given 2 sides.
Let's do the same thing we did in the first one.
Givens:
A = 8
B = 15
Find:
C
Substitute:
8^2 + 15^2 = c^2
Simplify
64 + 225 = c^2
Reduce:
289 = c^2
Let's now square root both sides
square root of 289 is 17
so we are left with this:
c=17
Phew, you did it!
Hope this helped :))
Answer:
The missing number is -5, which you get by subtracting -3 from -8 ((-8)-(-3)), or adding 3 to -8.
Answer:
X=36
Step-by-step explanation:
90-54=36
Right angle 90 subtract 54
The missing angle x is 36
