59.99 - 59.99 x saving rate = 42.89

with saving rate = r%

59.99 - 59.99 x r% = 42.89

so 59,99 ( 1 - r%) = 42.89

1 - r% = 42.89 : 59.99

1 - r% = 0,7150

r% = 1 - 0,7150

r = 28,5%

Answer:

a) p = 88\,cm, b) p = 24\,cm, c) p \approx 25.424\,m, d) p \approx 39.368\,cm

Step-by-step explanation:

a) The perimeter is the sum of the three sides of the internal square and the remaining sides of the external rectangle, that is:

p = 3\times 8\,cm + 2\times 4\,cm +2\times 20\,cm + 16\,cm

p = 88\,cm

b) The perimeter is the sum of the two sides of the internal triangle and the remaining sides of the external rectangle, that is:

p = 2\times 4\,cm + 2\times 6\,cm + 4\,cm

p = 24\,cm

c) The perimeter is the sum of the two sides of the circular section and the three sides of the lower rectangle, that is:

p = \frac{\pi}{2}\times 6\,cm + 8\,cm + 6\,cm + 2\,cm

p \approx 25.424\,m

d) The perimeter is the sum of the external sides of the triangle and rectangle, that is:

p = 10\,cm + 12\,cm + 12\,cm + 12\,cm - \sqrt{(12\,cm)^{2}-(10\,cm)^{2}}

p \approx 39.368\,cm

I need the x intercept and y intercept and slope y=mx +b form please
notka56 [123]

Answer:

x intercept: x=2.5

y intercept: y=5

slope: -2

formula: y=-2x+5

Step-by-step explanation:

The y intercept is where the line crosses the y axis. You can see that it does so at y=5. The x intercept is where the line crosses the x axis, but it is not immediately apparent where that happens from looking at this graph. However, we can determine that the slope of this line is -2, using the rise/run formula. This means that the formula of this line in y=mx+b form is:

y=-2x+5

Plugging in 0 for y to get the x intercept, you get:

0=-2x+5

2x=5

x=2.5

Thus, the x intercept is at x=2.5.
