It cost abdul $6.42 to mail a 42 oz. package. round to the nearest cent, what was his cost to mail per ounce?
a)$6.00
b)$1.50
c)$0.30
d)$0.15

divide and round to the nearest tenth
$2.30 divided by 9
a)$25.56
b)$0.25
c)$0.26
d)$25.55

jeanie's car averages 32 miles per gallon and the current cost of gasoline is $3.10 per gallon. to the nearest cent, what is the cost per mile?
a)$0.11
b)$0.10
c)$0.09
d)$0.08
(i wanna say b but i'm not sure)

1(d
2(c
3(b since your number is 0.096 you round 5 and up you go up 4 and below you go down 

Intersecting secant-tangent theorem states that if a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.so to break it down: 1. pq acts as the tangent and ps as the secant with an intersection at p.sr = 21rp = 3x + 3pq = 4x + 4following to equation: tangent squared = the two segments multiplied by each otherso (4x + 4) ^ 2 = (3x + 3) • (21) simplifies to 16x^2 - 31x - 47 = 0 or (16x - 47)(x + 1) x = -1 or x = 47/162. pq acts as the tangent and ps as the secant with an intersection at p (again! )sr = 16rp = xpq = 15(15) ^ 2 = 16 • x225 = 16xx = 225/163. the interesting chords are proportional to each other so a ratio is possible to set up: ap dp 10 3 + x = = —— = pc pb 8 xcross multiple to get 10x = (3 + x)(8)x = 12
