Answer:
<em>El administrador debe usar 37.5 litros de jugo al 5% y 12.5 litros de jugo al 25%.</em>
Step-by-step explanation:
<u>Sistemas de Ecuaciones</u>
Llamamos:
x = litros de jugo al 5% natural
y = litros de jugo al 25% natural
El administrador de la cafetería desea hacer 50 litros de jugo, luego:
x + y = 50 [1]
Esos 50 litros de jugo deben tener 10% de jugo natural. Como cada parte de x aporta 5% y cada parte de y aporta 25%:
5x + 25y = 10*50 = 500
Dividimos entre 5:
x + 5y = 100 [2]
Restamos [2] menos [1]:
4y = 50
y = 50/4 = 12.5
De [1] tenemos que:
x = 50 - y = 50 - 12.5 = 37.5
El administrador debe usar 37.5 litros de jugo al 5% y 12.5 litros de jugo al 25%.
50^2 + 30^2 = x^2
2500 + 900 = x^2
3400 = x^2
x = sqrt(3400)
x = 58.31
height is 58.31 feet ( round answer as needed)

if i can have brainliet that would be great
Step-by-step explanation:
Transform the question to an equation:
3 + 2x = 19
Solve:
2x = 16
x = 8
Check the answer:
3 + 2 (8) = 19
3 + 16 = 19
True
Answer:
Note that we need calculate the scores between the mean () and the mean plus 3 times the standard deviation. It is 3 times since the distance between the values given (513 and 759) divided by the standard deviation is 3 ()
So the rule say that 99.7% of data is between and , as it is a normal distribution half of 99.7% is between and . Hence 49.85% of people score between 513 and 759.
