a company sells circular mirrors. the price P pounds is proportional to the square of its radius r cm. a mirror with radius 20cm

Sever21 [200]

Answer:

P = 0.09r²

Step-by-step explanation:

Price, p is proportional to the square of its radius, r

P = k*r²

a mirror with radius 20cm has a price of £36

P = k * r²

36 = k * 20²

36 = k * 400

36 = 400k

k = 36/400

k = 0.09

Substitute the value of k into the equation:

P = k * r²

P = 0.09 * r²

P = 0.09r²

Your truck has a weight limit of 2100 pounds. A bag of cement weighs 75 pounds. Write an equality for x, the number of bags of c

Hitman42 [59]

You can haul 28 bags of cement.

Step-by-step explanation:

Given,

Weight limit of truck = 2100 pounds

Weight of each bag of cement = 75 pounds

Let,

x be the number of cement bags that you can haul

Weight of each bag * Number of bags = Weight limit

$75x = 2100$

Dividing both sides by 75

$\frac{75x}{75}= \frac{2100}{75}\\x=28$

You can haul 28 bags of cement.

IRISSAK [1]

Answer: There will be 7500000 users in the year 2000.

Step-by-step explanation:

Since we have given that

Number of users over the next decade in 1995 = 3000000

According to question, we have given that

there is increased by 150% by the year 2000.

so, Number of users will be increased in the year 2000 is given by

$\frac{100+150}{100}\times 3000000\\\\=\frac{250}{100}\times 3000000\\\\=2.5\times 3000000\\\\=7500000$

Hence, there will be 7500000 users in the year 2000.
