Answer:

  • Equation ; 800 = 50m + 250
  • Number of months = 11 months

Step-by-step explanation:

This is a linear relationship which means that it follows the equation;

y = mx + c

y will be the total after some months so will be $800

m will be the number of months

x is the amount the account increases by every month which is $50 here

c is the amount in the account before the $50 started being added which is $250.

800 = 50m + 250

50m = 800 - 250

m = (800 - 250) / 50

m = 11 months

One terameter equals 1012 meters. One micrometer equals 10 meter.
Butoxors [25]

Answer:

<h2>a)  10⁶metres</h2><h2>b) 10¹⁸metres</h2>

Step-by-step explanation:

Given One terameter equals 10¹² meters. One micrometer equals 10⁻⁶ meter, one nanometer equals 10⁻⁹meter;

a) The product of one terameter and one micrometer will be expressed as;

10¹²  * 10⁻⁶

Since the both have the same base, we will add their power according to one of the law in indices as shown

10¹²  * 10⁻⁶ = 10⁻⁶⁺¹²

= 10⁶metres

b) The quotient of one terameter and one micrometer can be gotten by taking their ratio as shown below;

Note that when taking the quotient, the power are subtracted

= \frac{10^{12} }{10^{-6} } \\= 10^{12-(-6)}  \\= 10^{12+6} \\= 10^{18}metres
