A magician is training for an underwater escape trick. Upon first trying, he could hold his breath for 60 seconds. Now, using a different technique, he can hold it for 35% longer. How long can the magician currently hold his breath?

Answers

ANSWER:  35% of 60 is 21 I'll let you figure out the rest.

Final answer:

The magician can hold his breath 35% longer than before, which equates to 81 seconds. This is accomplished by calculating 35% of the initial 60 seconds (21 seconds), and then adding this to the original 60 seconds.

Explanation:

The subject of this question is how to calculate percentages. In this case, we are given that the magician could initially hold his breath for 60 seconds and after employing a new technique, he can now hold his breath for 35% longer than the initial time. To find this out, we need to calculate 35% of 60 and add it to 60.

  1. First, calculate 35% of 60: 0.35 * 60 = 21 seconds
  2. Then add that result (21 seconds) to the initial time (60 seconds): 60 + 21 = 81 seconds.

Therefore, using his new technique, the magician can now hold his breath for 81 seconds.

At the Conic Company, a new employee's earnings E, in dollars, can be calculated using the function E = 0.05s + 30,000, where s represents the employee's total sales, in dollars. All of the new employees earned between $50,000 and $60,000 last year. Which value is in the domain of the function? Please show your workA $34,000
B $300,000
C $430,000
D $3,400,000

Answers

we know that E is in between 50,000 and 60,000. we substitute this in and find the values of s, which are 400,000 and 600,000. This becomes the domain therefore C is the answer. 

50,000=0.05s+30,000
20,000=0.05s
400,000=s

60,000=0.05s+30,000
30,000=0.05s
600,000=s

since E is in-between $50,000 and $60,000, s is in between 400,000 and 600,000, which is the domain. C is the answer.

Hope this helps.

A right Triangle is shown. if m angle H= 68°, What is GI? show work if you can and explain to me I don't understand

Answers

Ok, so we've been told that the angle H=68 degrees.

Let's now flip the right angled triangle 90 degrees clockwise.

If we do so, it turns out we'd have to find the opposite length of the right angled triangle (Opp) which is GI. We know that we have the adjacent (Adj) length of this triangle which is in fact 2cm. What we also know is that:

tan(β)=Opp/Adj *Whereby "β" is an angle.

As β=68 degrees, Opp=GI and Adj=2:

tan(68)=GI/2

Therefore:

GI = 2 * tan(68)

GI = 4.95 cm (to 2 decimal places)

If y=-8 when x=-2, find x when y=32

Answers

tryfind the relationships between x and y.
I am sure that it is y=4x because when you multiply 4 to the -2 it becomes -8...
and then you plug in the 32 into the y:
32=4x
 then divide 4 from the both sides for the value of x.
  x=8
y = -8  when  x = -2
y = 32  when  x = 8
