Answer:
$(3b+2)
Step-by-step explanation:
The cost of making b bracelets = 4+5b
The cost of making b necklaces = 8b+6.
To determine how much more it cost to make b necklaces than b bracelets, we simply subtract.
Extra Cost = Cost of b Necklaces-Cost of b Bracelets
=(8b+6)-(4+5b)
open the brackets
=8b+6-4-5b
Collect like terms
=8b-5b+6-4
=3b+2
It costs $(3b+2) more to make b necklaces than b bracelets.
Answer: y should be in the interval (0.4, 4)
Explanation:
The binomial 5y - 7 is in the interval (-5, 13) if and only if
-5 < 5y - 7 < 13
Solving the inequalities in this form is the same as solving equation. So, we add all sides of the inequalities by 7 so that
2 < 5y < 20
Then, we divide both sides by 5 to get the following inequalities
0.4 < y < 4
Hence y should be in the open interval (0.4, 4).
Answer:
Step-by-step explanation:
Answer:
V = 486
, or approx. 1,526.814
Step-by-step explanation:
V = *r²*(h/3)
plug in the numbers: V = * (9)² * (18/3)
simplify: V = * 81 * 6
simplify: V = 486, or approx. 1,526.814
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.
