The radius of a circle is increased from 6.00 to 6.06.

Oksana_A [137]

Answer:

a) Change in area = 0.72π m²

b) Estimated change in %age = 2%

Step-by-step explanation:

$Initial\,\, radius = r = 6 m\\\\Final \,\,radius = r_1 = 6.06 m\\\\Change\,\, in\,\,radius = dr =6.06 - 6 = .06 m\\\\$

$Area\,\,of\,\,circle= A=\pi r^2\\\\A=36\pi \,m^2\\\\Chang\,\, in\,\, area = dA= 2\pi r.dr\\\\dA=2\pi(6)(.06)\\\\dA=0.72\pi\,m^2\\\\Estimated\,\, \%age\,\, change=\frac{0.72\pi}{36\pi}\times 100\%\\\\=2\%$

Can advise on the solution?

maw [93]

Answer:

340

Step-by-step explanation:

If x is the amount of pages in the book we can write:

1/4x + 5 + 3/5(x - (1/4x + 5)) + 10 + 12 + 24 = x

1/4x + 51 + 3/5(3/4x - 5) = x

1/4x + 51 + 9/20x - 3 = x

7/10x + 48 = x

3/10x = 48

x = 160

Last week, Alan drove 196 miles. This week, he drove m miles. Using m, write an expression for the total number of miles he drov

lisov135 [29]

X=196+m

196 is for one week, and the next week he drove m miles, so the expression could be that the total number of miles (x) is the 196 plus the miles he drove this week (m)
