Which triangle is similar to triangle PQR using the Pieces of Right Triangles Similarity Theorem? Triangle SRP has measure of angle SRP equal to 90 degrees. Q is a point on the hypotenuse SP such that the segment QR is perpendicular to PS. T is a point outside the triangle on the left of S so that triangle QTS has the measure of angle QTS equal to 90 degrees.

Triangle RQS
Triangle TSQ
Triangle QST
Triangle SRQ

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

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
