176 kg/cm2 y se emplea un coeficiente de seguridad de 4. Considere la densidad del concreto de 2,200 kg/m3

answer: 0.95, d

step-by-step explanation:

first, you have to combine the percentages of costumers ordering pizza or salad. 25% (percent of salads ordered) plus 70% (percent of pizzas ordered) is equal to 95%. then, turn 95% into a fraction: 95/100. lastly, divide 95 by 100 and you will get 0.95, d.

you need to give us more information since we can't answer
