It would be D because when adding them together the only one that makes sense would be D. adding the exponents 5+4 = 9 so it would be 10^9
Answer:
6.25%
Step-by-step explanation:
discount/ normal price
5/80
And we are trying to find out the percentage, so
x/100
Set the 2 equations equal to each other
5/80=x/100
Cross multiply
80x=500
Divide by 80 on both sides
x= 6.25
Alright so I'm coming up with this on the fly; you have the first six letters (a,b,c,d,e,f) and 0-9 and your ten numbers. calculate the amount of possible combinations for the letters by simply writing them down.
ab, ac, ad, ae, a f- five
bc, bd , be, bf- four
cd, ce, cf- three
de, df- two
ef,- one.
adding these all together gets a total of 15 for the letters. now the numbers
01, 02, 03, 04, 05, 06, 07, 08, 09- nine
12, 13, 14, 15, 16, 17, 18, 19- eight
23, 24, 25, 26, 27, 28, 29- seven
34, 35, 36, 37, 38, 39- six
45, 46, 47, 48, 49- five
56, 57, 58, 59- four
67, 68, 69- three
78, 79- two
89- one
added together with a total of 45 combinations.
alright so, 45 different number combinations and 15 letter combinations. multiplying 15 by 45 should tell you the total possible combinations for a two letter and two number serial-number
Answer:
A Luis le quedan 70 kg de patatas.
Step-by-step explanation:
Para encontrar la respuesta, primero tienes que determinar la cantidad total de patatas que Luis ha vendido multiplicando la cantidad de kilos en cada bolsa por el número de bolsas vendidas:
2,5kg*10=25 kg
Ahora que sabes que Luis ha vendido 25 kg de patatas puedes restar esto de la cantidad de kilos que tenía para saber cuánto le queda:
95-25=70
De acuerdo a esto, la respuesta es que a Luis le quedan 70 kg de patatas.
