What you do is 20 divided by 4, which is 5. So then you times 32 by 5 and that's how you get 160.

aivan3 [116]

Answer:

Donna swims 8 km each week.

Step-by-step explanation:

To be able to find the answer, you have to consider that 1 km is equal to 1000 meters and with this, you can use  rule of three to find the kilometers in 8000 meters:

1 km  →  1000 meters

  x    ←   8000 meters

x=(1*8000)/1000=8 km

According to this, the answer is that Donna swims 8 km each week.

Answer:

  • x = 30
  • y = 105
  • z = 75

Step-by-step explanation:

You know the linear pair z° and 105° are supplementary angles, so ...

  z = 180 -105 = 75

The other base angle of the isosceles triangle has the same measure, 75°. __

Then x can be found either from the sum of interior angles of the triangle, or from the relation of 105° to the "remote interior angles". The first relation gives ...

75° +75° +x° = 180°   ⇒   x = 180 -150 = 30

The second relation gives ...

  75° +x° = 105°   ⇒   x = 105 -75 = 30

__

y° is supplementary to the left-side base angle, so is ...

  y = 180 -75 = 105

Of course, you could also figure y from the symmetry of the figure.

The values of x, y, z are 30, 105, 75, respectively.

How to find the average rate of change of a function
ollegr [7]

ANSWER

Average Rate of Change

=  \frac{f(b) - f(a)}{b - a}

EXPLANATION

To find the average rate of change of y=f(x) from x=a to x=b means finding the slope of the secant line joining the points

(a,f(a)) and (b,f(b))

The slope of the secant line joining these points is

=  \frac{f(b) - f(a)}{b - a}

This gives the average rate of change of the function.
