John's income increased by 4%. if his income rose by $850, find his previous amount

bearhunter [10]

Answer:

$21,250

Step-by-step explanation:

4% = 850

100% = x

Cross multiply the above to get 21,250

Another way of doing this is:

850 divided by 4 = 212.5

So every percent is equal to 212.5, so:

212.5 * 100 (for 100%) = 21,250

Answer:

Step-by-step explanation:

Garden roller is in the shape of cylinder.

So, one revolution = Curved surface area of the cylinder

diameter = 70 cm

radius = 70/2 = 35 cm

h = 100 cm

Curved surface area of the cylinder = 2πrh

= $2*\frac{22}{7}*35*100$

= 22000 square cm

Area covered in 15 revolutions = 15 * 22000

= 330000 square cm

2) Coin

diameter = 22 mm

r = 22/2 = 11 mm

Volume of coin = 66 mm

πr²h = 66

$\frac{22}{7}*11*11*h=66\\\\\\h=\frac{66*7}{11*11*22}\\h=0.17 mm$

Rammy has $9.60 to spend on some peaches and a gallon of milk. Peaches cost $1.20 per pound, and a gallon of milk cost $3.60.

lesya692 [45]

Answer:

Rammy can buy 5 pounds of peaches

Step-by-step explanation:

1.20(5) + 3.60 = 9.60

subtract the cost of the gallon from the total amount and then divide the leftover cost $6 by $1.20 and you'll get 5.
