É uma questão relativamente simples, o problema é cair em uma pegadinha do enunciado.
Se colocarmos que o jarro inicialmente tenha X ml, após Claudete beber 240 ml temos que X-240=Y. Então Claudete bebe 1/4 da jarra, por isso temos 3*Y/4=Z (Se ela bebeu 1/4, reataram 3/4). Depois, ela bebe 1/3 do volume inicial e o suco acaba, logo montamos a equação X/3=Z.
Agora temos um sistema com estas 3 equações:
--> X-240=Y
-->3Y/4=Z
-->Z=X/3
Juntando as 2 ultimas vc terá: X/3=3Y/4. E como Y=X-240.
X/3=3*(X-240)/4
Se resolver isto terá que X=432. logo a resposta é 'E'
Answer:
(X+9)x(X-4)
Step-by-step explanation:
1. write as a difference:
X^2+5X-36
2. factor the expressions:
X^2+9X-4X-36
3. factor the expression: Xx(X+9)-4(X+9)
Answer:
Your straight-time pay is $195.
Step-by-step explanation:
a) Data and Calculations:
Employee Regular Hourly Rate х Hours Worked = Straight-Time Pay
Wright, S. $8.00 36
Reardon, E. 7.50 18
Levitt, R. 16.20 30
Maguire, M. 10.25 243
Reyes, A. 14.525 31.125
Vadola, G. 26.675 25.625
b) If you earn $6.50 per hour and work 30 hours this week, your straight-time pay is $195 ($6.50 * 30). The straight-time pay is determined by multiplying the number of hours worked in a period by the hourly rate.
