Answer:
Part A: 90; Part B: 24.
Step-by-step explanation:
The number of blueberry muffins is 40% of the total number of muffins.
Part A: There are 36 blueberry muffins. This is 40% of the unknown number of muffins, x; this gives us
36 = 0.4x
Divide both sides by 0.4:
36/0.4 = 0.4x/0.4
90 = x
There were 90 total muffins.
Part B: 40% of the total number of muffins, 60, gives us the unknown number of blueberry muffins:
0.4(60) = x
24 = x
There were 24 blueberry muffins.
Answer:
1,333 frogs
Step-by-step explanation:
okay so we know that mass remains conserved no matter where you are.
same here ^^
if the total mass of brass is 200 kg
the total mass of the new frogs formed from it when put together will be the same :)
and if there were n such frogs formed
we have,
total mass = n × mass of each frog
200 = n × 3/ 20
n = 4000/ 3
so it becomes something like 1,333.33
that is nearly 1,333 frogs can be made out of 200 kg of brass each weighing 3/ 20kg (the last ones a bit less to make upto 200kg)

Explicación paso a paso:
Dado lo siguiente:
Número de bailarines = 156
Sea número de bailarines en una columna = c
Número de bailarines seguidos = c + 20
Multiplicar el número de bailarines en fila y columna dará el número total de bailarines.
Por lo tanto,
c * (c + 20) = 156
c² + 20c = 156
c² + 20c - 156 = 0
c² + 26c - 6c - 156 = 0
c (c + 26) - 6 (c + 26) = 0
(c + 26) = 0 o (c - 6) = 0
c = - 26 o c = 6
C no puede ser negativo
Por lo tanto,
Número de bailarines en columna = 6
Número de bailarines en fila = 20 + 6 = 26
About 12,000 I’m not sure but I searched it up and it says that
N is 2/3 because 1 minus 1/3 is 2/3
