Point H is between G and I. If HG = 8x + 7, HI = 3x - 2, and GI = 38, what would be the length of GH ?

Answers

Answer:

let's see what to do...

Step-by-step explanation:

H is between G and I.

G I = G H + H I

38 = 8 x + 7 + 3x - 2

38 = 11 x + 5

subtract the sides of equation minus 5

38 - 5 = 11 x + 5 - 5

33 = 11 x

divided the sides of equation by 11

33 ÷ 11 = 11 x ÷ 11

3 = x

So the lenght of (G H) is :

8 x + 7 -----¢ 8 (3) + 7 = 24 + 7 = 31

And we're done.

Thanks for watching buddy good luck.

Step-by-step explanation:

Question

Lisa lit a candle with a height of 8 inches. When lit, this candle loses 10% of its original  height every hour. Please complete the following sentence by writing the number in the blank.   Until the candle has been burning for at least _______ hours, the height of Jennifer's candle will be more than 7 inches.

Candle looses 10% of 8 inches, it equals:

8*0.1 = 0.8 inches an hour

Let x be required time, then:

8 - 0.8x > 70.8x <  8 - 70.8x  < 1x  < 1/0.8x  <  1.25or 1 hour 15 minutes

Students make 58.5 ounces of liquid soap for a craft fair. They put the soap in 4.5 ounce bottles and sell each bottle for $5.50. How much do the students earn if they sell all the bottles of liquid soap?

Answers

Step-by-step explanation:

first you want to divide the ounces of liquid soap we have by the ounce bottles we have (58.5 / 4.5 = 13 )

so now we know we have 13 bottles of liquid soap

then you want to multiply the 13 bottles of soap by how much they sell each bottle for ( 13 x 5.50 = 71.50 )

the answer: the students would earn $71.50 if they sell all the bottles of liquid soap

hope that helps :)

Oceanside bike rental shop charges 16 dollars plus 9 dollars an hour for renting a bike.Sam paid 52 dollars to rent a bike.How many hours did he pay to have the bike checked out?

Answers

Answer:

4 Hours

Step-by-step explanation:

Since the equation is:

y = 9x + 16

You have to find x

This is the logical way:

52-16 = 36 because thats the starting fee

So 36 divided by 9 equals 4

You do that because 9 is the charge per hr

So he rented it for 4 hours.

Proposed Exercise: Work-Energy TheoremIn the situation illustrated in the figure below, a 365 pile hammer is used to bury a beam. The hammer is raised to a height of 3.0 (point 1) above the beam (point 2) and released from rest, sinking the beam of 7.4 (point 3). The rails exert on the hammer a constant friction force equal to 54 . Using the work-energy theorem, calculate (a) the speed of the hammer at the exact instant it reaches point 2 and (b) the mean force exerted by the hammer on the beam when moving it from position 2 to 3.Tip: the force requested in item (b) is equal to the normal force that the beam exerts onthe hammer.
