Answer:

1. $9.86

2. $531.51

3. $49.81

4. $6.03

5. $25.13

Step-by-step explanation:

1. 15% of 65.75 = 9.8625 about 9.86 (asks only for the amount for the tip)

2. 18% of 450.50 = 81.01

450.50 + 81.01 = $531.51(Asks for total; the price of the food including tip).

3. 25% of 39.85 = 9.9625

39.85 + 9.9625 = 49.8125 about 49.81 (asks for total; the price of the food including tip).

4. 12% of 50.25 = 6.03 (Asks only for the amount of the tip)

5. 20% of 125.67 = 25.13400 about 25.13 (Only asks the amount of the tip)

Two gears in a machine are aligned by a mark drawn from the center of one gear to the center of the other. If the first gear has

Aleksandr [31]

Answer:

Step-by-step explanation:

for the first gear

revolutions/teeth

1 / 24

2 / 48

3 / 72

4 / 96

5 / 120

6 / 144

for the second gear

revolutions/teeth

1 / 40

2 / 80

3 / 120

4 / 160

the two marks will meet after 120 teeth, 5 revolutions of the first gear and 3 revolutions of the second.

the way to get that amount of teeth is

$24 = 2 \times 2 \times 2 \times 3 = {2}^{3} \times 3$

$40 = 2 \times 2 \times 2 \times 5 = {2}^{3} \times 5$

the Least Common Multiple equals the product of all factors, but those factors who are repeted for both numbers should be only once.

${2}^{3} \times 5 \times 3 = 120$

120 teeth are 5 revolutions for gear1 and 3 por gear2

given

A coat at a store is originally priced at $54.99

The store marks down the price down to $32.99

Required

the percent decrease

Step two:

the percent decrease= change in price/ old price*100

the percent decrease= 54.99-32.99/54.99*100

the percent decrease= 22/ 32.99*100

the percent decrease= 0.666*100

the percent decrease= 66.6%
