Jamal's job as a lifeguard pays 10 dollars an hour. during his summer vacation, jamal wants to earn $540 to buy a new cell phone. what is the minimum number of hours jamal should work in order to buy a new cell phone

Step-by-step explanation:

the minimum number of hours = 540/10 = 54 hours

minimum of 54 hours

Step-by-step explanation:

From the question, Since Jamal's job pay $10 per hour

To get $540 to buy a cell phone, the minimum amount of hours jamal have to work is calculated by dividing cost of cell phone by Jamal's pay per hour.

= cost of cell phone/ Jamal' s pay per hour

= 540/10

=54 hours

Therefore, Jamal has to work a minimum of 54 hours in order to buy the new cell phone.

I hope this is clear, please mark as brainliest.

∠1≅∠2 by the alternate exterior angles theorem.

step-by-step explanation:

given, a ∥ b and ∠1 ≅ ∠3 .we have to prove that e ∥ f

we know that ∠1≅∠3 and that a || b because they are given. we see that by the alternate exterior angles theorem. therefore, ∠2≅∠3 by the transitive property. so, we can conclude that e || f by the converse alternate exterior angles theorem.

we have to fill the missing statement.

transitivity property states that if a = b and b = c, then a = c.

now, given ∠1≅∠3 and by transitivity property ∠2≅∠3 .

hence, to apply transitivity property one angle must be common which is not in result after applying this property which is ∠1.

the only options in which ∠1 is present are ∠1 and ∠2, ∠1 and ∠4

∠1 and ∠4 is not possible ∵ after applying transitivity we didn't get ∠4.

hence, the missing statement is ∠1≅∠2.

so, ∠1≅∠2 by the alternate exterior angles theorem.
