In a discount clothing store, all sweaters are sold at one fixed price and all shirts are sold at another fixed price. If one sweater and four shirts cost $45, while four sweaters and five shirts cost $92, find the price of one sweater and the price of one shirt.

Answers

Say SH is the shirt cost and SW is the sweater cost:
SW + 3SH = 42
3SW+2SH = 56

Solve the first for SW:
SW = 42-3SH

Plug that into the second:
3(42-3SH) +2SH = 56

Simplify:
126 - 9SH +2SH = 56
70 = 7SH
SH = 10

Plug this back into the SW formula:
SW = 42 - 3SH = 42 - 3*10 = 12

Shirts cost $10, sweaters cost $12.

Seven integers, x1, x2, x3, x4, x5, x6, and x7, are picked at random from the set of all integers between 10 and 110, inclusive. If each of these integers is divided by 7 and the 7 remainders are all added together, what would be the sum of the 7 remainders?

Answers

Answer:

0+1+2+3+4+5+6=21

Step-by-step explanation:

Since integers are given as x1, x2, x3, x4, x5, x6, and x7. This means they are consecutive integers divisible by 7.

Thus no matter which 7 consecutive integers are these, their reminders will always be in the order of 0,1,2,3,4,5 & 6.

So their sum will be 0+1+2+3+4+5+6=21.

A pilot flew a jet from location A to B, a distance of 2500 meter,on the return trip the average speed was 20 percent faster than the outbound speed,the round-trip took 9 hours 10 minutes . What is the jet's speed from A to B.

Answers

Answer: The jet's speed from A to B would be 5.5 km/hr.

Step-by-step explanation:

Since we have given that

Distance = 2500 meter

Outbound speed be x

Average speed be $(100+20)/(100)x=(120)/(100)x=1.2x$

Time = 9 hours 10 minutes = $9(10)/(60)=9(1)/(6)=(55)/(6)$

According to question, it becomes,

$(2.5)/(x)+(2.5)/(1.2x)=(55)/(6)\n\n(1.2x+x)/(1.2x^2)=(55)/(6* 2.5)\n\n(2.2x)/(1.2x^2)=(11)/(3)\n\n(2.2)/(1.2x)=(11)/(3)\n\n2.2* 3=1.2x\n\n6.6=1.2x\n\n(6.6)/(1.2)=x\n\nx=5.5\ km/hr$

Hence, the jet's speed from A to B would be 5.5 km/hr.
