Kathy has a garden that is 15 feet wide and 20 feet long. she will plant 1 bulb per square foot. each bang contains 9 bulbs. how many bag does kathy need

34 bags

Step-by-step explanation:

Area =L*W

20*15 = 300 square feet

She needs to plant 300 bulbs

300/9 = 33.33333(33(1/3) bags

Since she need to purchase bags containing 9 bulbs each, she needs to buy 34 bags (It ill be 6 left since 34 bags =306 bulbs)

If she buys 33 bags  it will be only 297 (3 short)

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
