Step-by-step explanation:

Answer:

B

Step-by-step explanation:

The sides are not equal.  You substitute the coordinates into the equation which gives you -11=-4 x 3

which solves to -11 = -12

therefore the sides are not equal

Answer:

x = 9°

y = 119°

Step-by-step explanation:

Given,

y° = 61°+58° { the exterior angle formed by producing the side of triangle is equal to two non-adjacent angle}

or, y° = 119°

therefore, y° = 119°

Now,

52°+y°+x° = 180°{the sum of angle if triangle is 180°}

or, 52°+119°+x°= 180°

or, 171°+x° = 180°

or, x° = 180°-171°

or, x° = 9°

therefore, x° = 9°

Answer:

a) He will take 76 minutes in the triathlon

Step-by-step explanation:

He runs  1/5 of a mile in 1/20 f hour then, by simple inspection

1/5    ⇒    1/20       then    1/5 miles* 10    = 2 miles

                                        1/20*hours*10    = 1/10 hours

10/10 of an hour is 60 minutes

1/10 of an hour is 6 minutes

swimming

1/3 of a mile in 1/9 of hours then

1/3mile *6   = 2 miles

1/9 of an hour * 6 = 6/9 hours  or 2/3 of an hour

3/3 of an hour is 1 hour   = 60 minutes

2/3 of an hour is    =  40 minutes

In bike

4 miles  in  1/4 hour   then

4 miles *2   = 8 miles

1/4 hour* 2  =  1/2 hour = 30 minutes

Then he will do the triathlon in:

6 minutes running

40 minutes swimming

30 minutes in bike

Total 76 minutes

Step-by-step explanation:

3/4 + 1/4 since they both have a 4 as the denominator you only have to add the top since they made it easy. and since that would be 4/4 your answer would be 1 whole.

do they give the whole amount of both trails together? then someone would be able to answer this so pls add that

None of the options are correct because no table shows the 1 gallon per minute.

Given that,
To determine which of the table shows the rate of 1 gallon per minute.

Rate of change is defined as the change in value with rest to the time is called rate of change.

Here.
Table 1,
Rate = number of gallon / minute = 1 / 5 / [10/5] = 1/10 gallon per minute
Similarly.
Table 2
Rate = 2 / 3  gallon per minute
Table 3
Rate = 1 / 2  gallon per minute
Table 4
Rate = 3 / 8  gallon per minute

Thus. none of the options is correct because no table shows the 1 gallon per minute.

[tex]\frac{3}{5} +\frac{1}{4} +\frac{3}{8} =[/tex] Distance Janie walked

First add [tex]\frac{1}{4} and\frac{3}{8}[/tex] canvert 1/4 by multiplying by 2/2 to get a commmon denominator.

[tex]\frac{1}{4} *\frac{2}{2} =\frac{2}{8}[/tex]

[tex]\frac{2}{8} +\frac{3}{8} =\frac{5}{8}[/tex]

Now find a common denominator for 3/5 and 5/8 by multiplying 3/5 by 8/8  and 5/8 by 5/5.

[tex]\frac{3}{5}*\frac{8}{8}=\frac{24}{40}[/tex]

[tex]\frac{5}{8}*\frac{5}{5}=\frac{25}{40}[/tex]

Now add them.

[tex]\frac{24}{40}+\frac{25}{40}=\frac{49}{40}=1\frac{9}{40}[/tex]miles

You can also convert all to decimals and add.

3/5 = .6

1/4 = .25

3/8 = .375

.6 + .25 + .375 = 1.225

Also 1 [tex]\frac{9}{40}[/tex] = 1.225

Answer:

12

Step-by-step explanation:

P(x) has infinitely many solutions, but I am going to find the easiest one, which would be a linear equation.

First, notice that x-2 perfectly divides into itself.

Then, if you add 12 to x-2, you will end up with a remainder of 12. Therefore, P(x) would be x-2+12 = x+10.

Now that we know P(x), we can directly plugin 2 to find out P(2):

2+10 = 12

Therefore, P(2) = 12.

Answer:

The steady-state percentage of residents who are uninvolved = 0.33%

Step-by-step explanation:

This is an example of the natural rate of unemployment given the steady-state percentage of residents who are uninvolved in the question. From the question, the break-up rate represents the rate of job separation in the natural rate of unemployment, while the rate that enters into a relationship represents the rate of job finding in the natural rate of unemployment.

The formula for the natural rate of unemployment = U/L = s / (s + f)

So, the steady-state percentage of residents who are uninvolved = U/L = s / (s + f)

Where U/L = natural rate of unemployment

               s = rate of job separations

             f = rate of job finding

s = 5 percent

f = 10 percent

The steady-state percentage of residents who are uninvolved

=  5% / (5% + 10%)

= 0.33%
