The tables show the cost of different numbers of t-shirts ordered at two different stores, Store C and Store D: Store C Number of T-shirtsCost (in $) 2$12 4$24 8$48 Store D Number of T-shirtsCost (in $) 3$21 6$42 9$63 Which of these explains which store has a better buy? Store C, because the ratio of the number to the cost is 6:1 in Store C and 7:1 in Store D. Store C, because the ratio of the number to the cost is 1:6 in Store C and 1:7 in Store D. Store D, because the ratio of the number to the cost is 2:14 in Store C and 3:24 in Store D. Store D, because the ratio of the number to the cost is 14:2 in Store C and 24:3 in Store D.

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.

x^3-4x^2+3x-2/x^2+1

step-by-step explanation:

factor the numerator and denominator and cancel the common factors

third choice down

step-by-step explanation:

the first inequality is based on the number of adults and campers, and the second inequality is based on the cost of feeding both the adult and the camper.

we know that there is room for 525 people max.   it's ok to have less than 525, but it's not ok to have more than 525, so the inequality is less than or equal to.   the number combination of adults (x) and campers (y) cannot exceed this 525 max.   therefore:

x + y ≤ 525

now we talk about cost.   it costs $9 to feed one adult, so depending upon the number of adults you have (x) depends upon how much it will cost to feed that number of adults.   same with the campers, who cost $5 to feed.   the adults can be represented by 9x and the campers can be represented by 5y.   since the budget cannot exceed 1,200, the second inequality is:

9x + 5y ≤ 1200
