This is a sequence because the points form a straight line. The expression is: t(n) = 30 + 2x, x is number of weeks. On her 18th birthday, that is 8 years after her 10th. that means 416 weeks have passed since her 10th birthday. Plug 416 into the equation to get: t(416) = 30 + 2(416) = $862. She will have $862 to Spend.

The sum of all angles in a triangle is always <em>180°</em>. Our triangle has <em>2</em> equal angles and one <em>40°</em> angle. That means that the size of those two angles is <em>(180° - 40° ) / 2 = 70°</em>. Then from <em>180°</em> or half circle subtract <em>70°</em> and you will end up with <em>110°</em> which the value of <em>x</em>.

Answer:
Step-by-step explanation:
1.
x/50= 84/100
x= 4200/100
x= 42
Needed to score a 42/50 to get an 84%
2.
x/75 = 96/100
x= 7200/100
x= 72
Needed to score a 72/75 to get a 96%
