Por medio de sistema de ecuaciones:
*adultos (a) = $400
*niños (b) = $150
total de entradas : a + b = 600 ecua 1
dinero recaudado:
400a + 150b = 196 250 ecua 2
operamos:
a + b = 600 ecua 1
400a + 150b = 196 250 ecua 2
--------------------------
(-150) a + b = 600
400a + 150b = 196 250
-----------------------
- 150a - 150b = -90 000
400a + 150b = 196 250
-----------------------
250a = 106 250
a = 106 250/250
a = 425 adultos
a + b = 600
425+b =600
b = 600-425
b = 175 niños
comprobacion:
400a + 150b = 196 250
400(425)+150(175)=196 250
170 000 + 26 250 = 196 250
196 250 = 196 250

Answer: 17.28
Step-by-step explanation:
To figure out the volume of this solid you will need to do a multiplication problem. Use the equation *r^2*h
Pi = 3.14
R= 1
H= 5.5
So answer will be 17.28 ( because we round it up!)
Now for cubes you will need to use the equation V=L*W*H
2.54,2,-1.79,-4
Step-by-step explanation:
gretest is 2.54 because 2.54 is nearer to 3so it is greatest. then 2 is smaller than 2.54 and then -1.74 and -4 because the number which is greater in negative is the most smallest number.
for , another example -1 is greater than-100.
