3/4 +4/5
find the common denominator which is 20
multiply by 5 for 3/4
(3)(5)/(4)(5)=15/20
multiply by 4 for 4/5
(4)(4)/(5)(4)=16/20
15/20+16/20
=31/20
answer:
31/20, 1 11/20 and 1.55
Answer:
See Below:
Step-by-step explanation:
Average is take by adding all the terms together and dividing by the number of terms. In this case it terms is people in the room.
22= (25+18+17+13+24+x)/6
Where 22 is the average age. The numerator is all the known ages added together, plus x which is the age of the person who just entered. Divided by 6 because you are finding the average age of 6 people.
22 = (25+18+17+13+24+x)/6 Multiply both sides by 6
132= 97+ x Subtract 97 from both sides.
35 = x
The person who just entered the room is 35 years old.
Answer:
Step-by-step explanation:
¿Entre que números naturales consecutivos se encuentra cada raíz?
Bueno en este caso debes empezar por el 1 en adelante, pero solo sucede en números impares consecutivos. Solamente debes sumar 1,3,5,7,9,11,13,15,17,19 ..... en adelante, y en cada suma de cada sucesión encontraras un cuadrado. Ojo solo sumando en orden, tampoco sumarás 3+9, ya que te dará 12 y 12 No tiene raíz.
1+3=4,√4=2
4+5=9, √9=3
9+7=16, √16=4
16+9=25, √25=5
25+11=36, √36=6
36+13=49, √49=7
49+15=64, √64=8
64+17=81, √81=9
81+19=100, √100=10

A SI CONSECUTIVAMENTE SIEMPRE OBTENDRÁS CADA RAÍZ
¿Entre que números naturales consecutivos se encuentra cada raíz?
R= En los número impares consecutivos, comenzando por el 1 en adelante.
0.8 is the correct answer
