hter will be on Flight BM1264. Jenny will arrive at the airport ten minutes before the flight arrives and will leave with her daughter fifteen minutes after it lands. Her journey to the airport takes 25 minutes. Jenny wants to do all the preparation for the meal before leaving for the airport. It takes 30 minutes to prepare. She will leave for the airport straight after finishing the preparation. Jenny has bought a 2.4kg chicken. It takes 35-45 minutes per kg plus an additional 30 minutes to cook the chicken. Jenny will start cooking five minutes after getting back from the airport. QUESTION IS: HOW LATE CAN THEY EAT DINNER, ALSO PLANE ARRIVES AT 4PM

The addition is one of the four fundamental mathematical operations. Jenny can have dinner at 7 pm and 7.5 mins.

<h3>What is Addition?</h3>

The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.

The time can be calculated as,

  • Time taken for preparation = 30 min
  • Time is taken to travel to airport = 25 mins
  • She will wait for 10 mins before the flight arrive = 10 min

Flight lands at 4 pm

  • She will leave 15 mins after the flight lands = 15 mins
  • It takes 25 mins to travel back home ⇒ 15 + 25 mins
  • She will start cooking after 5 mins ⇒ 15+25+5 min

Jenny has bought a 2.4kg chicken. It takes 35-45 minutes per kg plus an additional 30 minutes to cook the chicken. Time needed for cooking the chicken = (2.5×45 + 30) = 142.5 min

⇒ 15+25+5+142.5 min

Thus, the total time it takes for Jenny to cook the food starting when the flight lands are ⇒ 187.5 mins = 3 hours 7.5 mins

Since the flight lands at 4 pm

⇒ 4 pm + 3 hours 7.5 mins

⇒ 7 pm and 7.5 mins

Hence, Jenny can have dinner at 7 pm and 7.5 mins.

Christopher deposited $1 in a savings account earning
andriy [413]

Answer: He would have $1.33 after 3 years glad to help please mark brainliest!

Step-by-step explanation:

using simple interest formula: A = P(1 + r)^t

A= Total amount in 3 years

P=starting total

r=rate of percent as a decimal

t=time in years

A=1(1+0.10)^3

A=1(1+0.10)^3

A=1(1.10)^3

A=1(1.331)

A=1.331

A=1.33

How do i solve this -6n-20=2n+4(1-3n)
Leno4ka [110]
Hi Ivan

-6n - 20 = 2n + 4(1 - 3n)
-6n - 20 = 2n + 4 - 12n
Combine like terms
-6n - 20 = 2n - 12n + 4
-6n - 20 = -10n + 4
-6n + 10n = 4 + 20
4n = 24
n = 24/4
n= 6

I hope that's help! If you have any further questions please let me know !

What is the answer / product of 8x2
Mademuasel [1]

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "x2"   was replaced by   "x^2".  

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    8*x^2-(8)=0  

Step by step solution :

STEP

1

:

Equation at the end of step 1

 23x2 -  8  = 0  

STEP

2

:

STEP

3

:

Pulling out like terms

3.1     Pull out like factors :

  8x2 - 8  =   8 • (x2 - 1)  

Trying to factor as a Difference of Squares:

3.2      Factoring:  x2 - 1  

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

        A2 - AB + BA - B2 =

        A2 - AB + AB - B2 =

        A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check : 1 is the square of 1

Check :  x2  is the square of  x1  

Factorization is :       (x + 1)  •  (x - 1)  

Equation at the end of step

3

:

 8 • (x + 1) • (x - 1)  = 0  

STEP

4

:

Theory - Roots of a product

4.1    A product of several terms equals zero.  

When a product of two or more terms equals zero, then at least one of the terms must be zero.  

We shall now solve each term = 0 separately  

In other words, we are going to solve as many equations as there are terms in the product  

Any solution of term = 0 solves product = 0 as well.

Equations which are never true:

4.2      Solve :    8   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

4.3      Solve  :    x+1 = 0  

Subtract  1  from both sides of the equation :  

                     x = -1

Solving a Single Variable Equation:

4.4      Solve  :    x-1 = 0  

Add  1  to both sides of the equation :  

                     x = 1

Two solutions were found :

x = 1

x = -1
