Emily's figurine is 17 inches taller than Chen's figurine

Step-by-step explanation:

Emily and Chen built clay figurines for art class

Emily figurine is 5' 1" tall
Chen's figurine is 3' 8" tall

We need to find how much taller is Emily's figurine than Chen's in inches

To solve this problem we must to change the heights of the two figurines to inch

∵ Emily's figurine is 5' 1" tall ⇒ 5 feet and 1 inch

∵ 1 foot = 12 inches

∴ The height of Emily's figurine = 5(12) + 1

∴ The height of Emily's figurine = 60 + 1

∴ The height of Emily's figurine = 61 inches

∵ Chen's figurine is 3' 8" tall ⇒ 3 feet and 8 inches

∵ 1 foot = 12 inches

∴ The height of Chen's figurine = 3(12) + 8

∴ The height of Chen's figurine = 36 + 8

∴ The height of Chen's figurine = 44 inches

To find how much taller is Emily's figurine than Chen's in inches subtract their heights

∵ The difference between the two figurine = 61 - 44

∴ The difference between the two figurine = 17 inches

∴ Emily's figurine is 17 inches taller than Chen's figurine

Emily's figurine is 17 inches taller than Chen's figurine

Hillary is planning an expensive surprise party. She is choosing between two venues. The banquet hall at Hotel A will cost $431

In-s [12.5K]

Answer: Hillary would have to invite 15 people before the cost of having the party at Hotel B is less than the cost of having a party at Hotel A

Step-by-step explanation:

Let x represent the number of guests that Hillary would invite.

The banquet hall at Hotel A will cost $431 to rent the room and $38 per guest. This means that the total cost of hosting x guests at hotel A is

38x + 431

The banquet hall at Hotel B will cost $747 to rent the room and $16 per guest. This means that the total cost of hosting x guests at hotel B is

16x + 747

For the cost of having the party at Hotel B to be less than the cost of having a party at Hotel A, it means that

16x + 747 < 38x + 431

747 - 431 < 38x - 16x

316 < 22x

22x > 316

x > 316/22

x > 14.36

A machine shop is manufacturing a pair of gears that need to be in a ratio as close to 1.1839323 as possible, but they can’t mak

Afina-wow [57]

Answer: Driven gear will have 50 teeth, and driver gear will have 42 teeth

Step-by-step explanation: First we have to know the formula of gear ratio which is started below

(No of teeth on driven)/(No of teeth on driver)

Note: we should all know in the combination of a gear system, we have two gears, the driver gear and the driven gear

So since the least amount of teeth for any gear is 50, we assume the no of teeth on the driven is 50

And no of teeth on the driver is x

50/x = 1.1839323

Cross multiply

x x 1.1839323 = 50

x = 50/1.1839323

x = 42.23

To the nearest whole number = 42

So therefore, number of teeth on the driver gear is 42
