Answer:
Step-by-step explanation:
We khow that A is the sum of all odd numbers that are less than 100
So A= 1+3+5+...+99
We can calculate this sum without adding all this numbers one by one
A = the number of terms *( first term + last one ) over 2
To get the number of terms we substract the first term from the last term then we add one
We khow that odd numbers are wiritten this way : 2*n +1 where n is an integer
So 99= 2*49+1
1= 2*0+1
So the number of terms is : 49-0+1 =50
So A= 50*(1+99)/2 = 2500
Foloowing the same method we get :
B= (49-1+1)*(2+98)/2= 2450
A>B
B. slope is -1/2
This is because the m-value aka the slope is always the reciprocal if the line is perpendicular
Answer:
128,158 hectáreas
Step-by-step explanation:
Aquí, en esta pregunta, nos interesa calcular las hectáreas totales de trigo que se sembraron entre los tres estados.
Para calcular esto, simplemente sumamos las hectáreas de trigo que se sembraron en cada uno de los estados.
Matemáticamente;
Eso sería; 84,092 + 42,634 + 1,432 = 128,158 hectáreas
Look at attached photo
first divide each line into the number as shown in the denominator
