There's 5 1/8 cups of water left in the pitcher.

- 5 1/2 = 11/2

- 11/2 = 44/8

- 44/8 - 3/8 =41/8

- 41/8 = 5 1/8

a car dealer buys a luxury car for $65,200 and sells it for 85,650. What is the percent increase in the price of the cara car de

nika2105 [10]

Answer:

The percent increase in the price of the car is <u>31.36%</u>.

Step-by-step explanation:

Given:

A car dealer buys a luxury car for $65,200 and sells it for $85,650.

Now, to find the percent increase in the price of the car.

Cost price of the luxury car = $65,200.

Sell price of the luxury car = $85,650.

So, the price of the car increased by:

Sell price of the luxury car - Cost price of the luxury car.

$=\$85,650-\$65,200\\\\=\$20,450.$

<em>Thus, the price of car increased by $20,450.</em>

Now,to get the percent increase in the price of the car:

$\frac{20450}{65200} \times 100$

$=0.3136\times 100$

$=31.36\%.$

Therefore, the percent increase in the price of the car is 31.36%.

A store sells candy at $.50, $1, $1.50, $2, and $3 per kilogram. you can see that the unit price of candies that $3 buy very inv

olga nikolaevna [1]

Answer:

constant of variation = 3

Step-by-step explanation:

Given that a store is selling different candies costing $.50, $1, $1.50, $2, and $3 per kilogram.

As given

Amount available to buy candies = $ 3

Suppose

Unit price of candies = x

Number of candies bough = y

Constant of variation = k

As we know the unit price of candies and number of candies bought vary inversely. As the unit price would increase the the number of candies bought in available amount ($3) would decrease.

So our formula to calculate formula for constant of variation would be as shown below:

k= xy →(1

Case 1

if we take unit price x to be $0.5, then we can buy 6 kg of candies in $ 3. In this case constant of variation can be found from above equation (1) as follows:

k = (0.5)(6) = 3

Case 2

if we take unit price x to be $1, then we can buy 3 kg of candies in $ 3. In this case constant of variation can be found from above equation (1) as follows:

k = (1)(3) = 3

Case 3

if we take unit price x to be $1.5, then we can buy 2 kg of candies in $ 3. In this case constant of variation can be found from above equation (1) as follows:

k = (1.5)(2) = 3

Case 4

if we take unit price x to be $2, then we can buy 1.5 kg of candies in $ 3. In this case constant of variation can be found from above equation (1) as follows:

k = (2)(1.5) = 3

Case 4

if we take unit price x to be $3, then we can buy 1 kg of candies in $ 3. In this case constant of variation can be found from above equation (1) as follows:

k = (3)(1) = 3

So, our constant of variation is 3.

Can someone pls help me

Answer:

6π Km

Step-by-step explanation:

The arc length is calculated as

arc = circumference of circle × fraction of circle

= 2πr × $\frac{120}{360}$

= 2π × 9 × $\frac{1}{3}$

= 18π × $\frac{1}{3}$

= 6π Km ← exact value
