Mr jones is planning to pant grass and place afence in a small area for his dog. The rectagular dimension are 12×15 feet. The gr
goldenfox [79]

Answer:

A) The total feet needed for the fence total perimeter is 54 feet

B) The total cost of fence is $432

C) The square feet of grass needed foe the total area is 180 square feet

D) The total cost of the project is $572

Step-by-step explanation:

Given as :

The dimension of rectangular field

Length of rectangular field = L = 12 feet

width of rectangular field = w = 15 feet

The cost of grass per square foot = 50 cents = $0.5    ( ∵ 1 cents = $0.01 )

The cost of small fence = $8 per linear foot

Now, According to question

A ) Let The total feet needed for the fence total perimeter = A feet

∵ Perimeter of rectangular field = 2 × Length + 2 × width

Or, A = 2 × L + 2 × w

Or, A = 2 × 12 feet + 2 × 15 feet

Or, A = 24 feet + 30 feet

∴ A = 54 feet

So, The total feet needed for the fence total perimeter = A = 54 feet

B ) Let The total cost of fence = $B

So, The total cost of fence = The cost of small fence × perimeter of fence

i.e B = $8 × 54 feet

∴ B = $432

So,The total cost of fence = B = $432

C) Let the square feet of grass needed foe the total area = C square feet

∵The Area of rectangular fence = Length × width

Or, The square feet of grass needed foe the total area = Area of rectangular fence = L × w

i.e C = 12 feet × 15 feet

Or, C = 180 feet²

So,The square feet of grass needed foe the total area = C = 180 square feet

D) Let The total cost of grass = $D

∵ The cost of grass per square foot = $0.5

So,Total cost of grass = $0.5 × Area of fence

i.e D = $0.5 ×  180 feet²

Or, D = $90

So, The Total cost of grass = D = $90

E) Let the total cost of the project = $E

∵Mr. Jones spend additional $50 for tools

So, The total cost of the project =  money spent on tools + total cost of fence + Total cost of grass

i.e E = $50 + B + D

Or, E = $50 + $432 + $90

∴ E = $572

So, The total cost of the project = E = $572

Hence,

A) The total feet needed for the fence total perimeter is 54 feet

B) The total cost of fence is $432

C) The square feet of grass needed foe the total area is 180 square feet

D) The total cost of the project is $572  Answer

Telemarketing. the probability that a call will reach a live person is 0.2. the calls are independent. (a) a telemarketer places
Sergeeva-Olga [200]

Solution: Telemarketing. the probability that a call will reach a live person is 0.2. the calls are independent. (a) a telemarketer places 5 calls. what is the probability that none of them reaches a live person.

Answer: The given random experiment can be considered as binomial experiment with probability of success = 0.2 and number of trials = 5

Therefore, we have:

n=5,p=0.2,q=(1-p)=1-0.2=0.8

Let x be the number calls that reach to live person.

We have to find P(x=0)

Using the binomial probability distribution, we have:

P(x=0)=\binom{5}{0}0.2^{0} (1-0.2)^{5-0}

                 =1 \times 1 \times 0.8^{5}

                 =0.3277

Therefore, the probability that none of them reaches a live person is 0.3277

Write a polynomial in standard form with zeros at -2 and 3 !!!!! PLZ HELP
lara31 [8.8K]

If the zeros are -2 and 3, then the factored form would be

(x+2) and (x-3)  

-2+2 = 0 and 3-3 = 0

A polynomial is written as ax^2 + bx + c

Expand (x+2) (x-3) using FOIL: Multiply each tern in one set of parenthesis by each term in the other set and then simplify by combining like terms:

x*x + x*-3 + 2*x + 2*-3

x^2 -3x + 2x -6

Polynomial in standard form:

x^2 -x -6

How many 3 over 8 pound bags of trail mix can be made from 6 and 3 over 8 pounds of trail mix ? Write a division expression
antoniya [11.8K]

Answer:

\frac{\frac{51}{8}} {\frac{3}{8}}

17 bags.

Step-by-step explanation:

We are asked to find the number of bags with weight 3/8 pound can be made from 6\frac{3}{8}.

To find the number of

\text{Number of bags that can be made from available mix trail}=6\frac{3}{8}\div \frac{3}{8}  

Convert mixed fraction into improper fraction.

\text{Number of bags that can be made from available mix trail}=\frac{51}{8}\div \frac{3}{8}  

Since we know that dividing a fraction with another fraction is same as multiplying the 1st fraction with the reciprocal of 2nd fraction.

\text{Number of bags that can be made from available mix trail}=\frac{51}{8}\times \frac{8}{3}  

After cancelling out 8 from numerator and denominator we will get,

\text{Number of bags that can be made from available mix trail}=\frac{51}{3}  

\text{Number of bags that can be made from available mix trail}=17  

Therefore, 17 bags each of weight 3/8 pounds can be made from 6\frac{3}{8} pounds of mix trail.
