$30.00-$25.06=$4.94. Kala used $4.94 on her card for the last call. 13cents per minute, divide 4.94/13=38, her last call 38 minute.

Is the sum of 4.2 and the square root of 2 rational or irrational?
andrew-mc [135]
A rational number can be expressed as a fraction with an integer numerator and denominator. The square root of 2 is irrational, and adding 4.2 doesn't change this, since there are no integers that, when divided, form this sum.

the birth rate in a certain country in 1994 was 14,6 birthd per thousand population. in 2004 the birth rate was 14.32 per thousa
amm1812

Answer:

y(x)=-0.028x+14.6

Step-by-step explanation:

Birth Rate in 1994 =  14.6 births per thousand population.

Birth Rate in 2004 =  14.32 births per thousand population.

A linear equation is of the form: y=mx+c

Where:

  • x=years after 1994
  • y=the birth rate
  • m=Yearly Birth Rate

First, we determine the birth rate per year

m=\dfrac{14.32-14.6}{10-0}\\=\dfrac{-0.28}{10}\\m=-0.028

Therefore, a linear equation that relates y in terms of x is of the form:

y(x)=-0.028x+c

When x=0, y=14.6

14.6=-0.028(0)+c

c=14.6

Therefore, the linear equation that relates y in terms of x is:

y(x)=-0.028x+14.6

C because the x's repeat with the 3 and 3. If the x's repeat it is not a function.

Hope that helps.

Answer:

330=40x+50

Step-by-step explanation:

then you would -50 from both sides

280=40x

then you would divide both sides by 40 to isolate x

7=x

so that means it would take 7 weeks
