Answer:
30 cm^2
Step-by-step explanation:
a = 13 cm
b = 12 cm
using Pythagorean theorem:
a^2 = b^2 + c^2
--> c^2 = a^2 - b^2 = 13^2 - 12^2 = 169 - 144 = 25
--> c = √25 = 5
The area of that right triangle is:
S = b.c / 2 = 12 . 5 / 2 = 30 (cm^2)
First you have to convert the denominators to the Lowest Common Multiple (unless the denominators are equal, of course).
Example 1/4 + 1/2
The LCM of 2 and 4 = 4 so we can write 1/2 as 1*2/2*2 = 2/4.
Now we can add:-
1/4 + 2/4 = 3/4.
Same thing goes for subtraction.
Example 2:-
5/6 - 1/7 :-
LCM of 6 and 7 = 6*7 = 42 so we have:-
5*7 / 6*7 - 1*6 / 7*6
= 35/42 - 6/42 = 29/42
Answer:
it's 6:10
12:20
Step-by-step explanation:
when u add 6+10 u get = 16
then divide 32 beads from 16.
then u get a value of a bead ...n it's 2.

Answer:
B=0.10x+2
Step-by-step
sponsor b is paying .10 x 52 pins + $2. = 5.20 + 2 = 7.20
it isn’t the 2 times 52
it is not subtracting the money
and we have to consider the 52 pins as X
Multiply 3 by 2 and you get six I think
