A bag of fertilizer covers 3000 square feet of lawn. Find how many bags of fertilizer should be purchased to cover a rectangular lawn 260 feet by 120 feet. Round up to the nearest integer

Answers

Answer 1

Answer:

The number of bags of fertilizer should be purchased to cover a rectangular lawn 260 feet by 120 feet is 9.53 bags.

First step is to find the area of the lawn

Area = 260 ft × 110 ft

Area = 28600 ft2

Second step is to calculate how many bags of fertilizer

Number of bags=Area/3,000ft

Number of bags=28600 ft / 3000 ft

Number of bags= 9.53 bags

Inconclusion the number of bags of fertilizer should be purchased to cover a rectangular lawn 260 feet by 120 feet is 9.53 bags.

Answer 2

Answer: The first step is to find the area of the lawn. This can be done by multiplying its dimensions, so: 260 x 120. This equals 31,200.

Now to find how many bags of fertilizer are needed, divide 31,200 by 3000. This equals 10.4, but must be rounded up to 11bags of fertilizer.

Answer:

option-A

Step-by-step explanation:

we are given

$6b^2+3b$

we can factor each terms

and then we can take common terms among them

$6b^2=2* 3* b* b$

$3b=1* 3* b$

we can replace it

and we get

$6b^2+3b=2* 3* b* b +1* 3* b$

now, we can take out common terms

we can see that common terms are 3 and b

$6b^2+3b=3b(2* b+1)$

we can simplify it

$6b^2+3b=3b(2b+1)$

Answer:

Its A.

Step-by-step explanation:

6b^2 + 3b.

One day, the hours without daylight in a particular city was 17 3/4 hours. What was the number of hours of daylight? PLS help me ASAP!

Answers

Answer:

6 ¼ hours of Daylight

Step-by-step explanation:

a day = 24 hours
you know that there was 17 ¾ hours of no day light
17 ¾ = 17.75
24 - 17.75 = Daylight hours
daylight hours = 6.25

Choose the correct simplification of the expression (2x − 6)(3x2 − 3x − 6).6x3 − 24x2 + 6x + 36
6x3 − 24x2 + 6x − 36
6x3 + 24x2 − 6x + 36
6x3 − 24x2 + 6x + 12

Answers

If you would like to solve (2x - 6) * (3x^2 - 3x - 6), you can do this using the following steps:

(2x - 6) * (3x^2 - 3x - 6) = 2x * 3x^2 - 2x * 3x - 2x * 6 - 6 * 3x^2 + 6 * 3x + 6 * 6 = 6x^3 - 6x^2 - 12x - 18x^2 + 18x + 36 = 6x^3 - 24x^2 + 6x + 36

The correct result would be 6x^3 - 24x^2 + 6x + 36.

Answer:

Option A is correct.

Correct simplification of the given expression = $6x^3-24x^2+6x+36$

Step-by-step explanation:

Given the expression: $(2x-6)(3x^2-3x-6)$

The following steps required for the multiplication of polynomials are:

Distribute each terms of the first polynomial to every term of the second polynomial.

Combine like terms

Apply these steps to the given expressions;

$2x(3x^2-3x-6) -6(3x^2-3x-6)$

when you multiply two terms together you must multiply the coefficient (numbers) and add the exponent.

⇒ $6x^3-6x^2-12x -18x^2 +18x +36$

Combine like terms;

$6x^3-24x^2+6x+36$

Therefore, the correct simplification of the given expression is, $6x^3-24x^2+6x+36$

Mike can cut a 40 foot by 20 foot yard with a push mower in 25 minutes. At this rate, how many more minutes would it take him to cut a 40 foot by 30 foot yard?

Answers

The time required to cut the area of 40 feet by 30 feet will be 37.5 minutes.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Mike can cut a 40-foot by 20-foot yard with a push mower in 25 minutes. The time required for 40 foot x 30-foot area will be calculated as:-

40 x 20 foot yard = 25 minutes

800-foot yard = 25 minutes

1 foot yard = 25 / 800

( 40 x 30 ) foot yard = ( 25 / 800 ) x ( 40 x 30 )

1200 foot yard = ( 25 / 800 ) x ( 1200)

1200-foot yard = 37.5 minutes

Therefore, the time required to cut the area of 40 feet by 30 feet will be 37.5 minutes.

area of the yard is 40 .20 = 800sq ft
time taken = 25 mins
time taken to mow 1sq ft = 25/800 mins
time taken to mow 40 .30 =1200sq ft = ( 25 .1200)/800 = 371/2 mins
thus the extra time taken will be 371/2-25 = 121/2 mins
