Joanne and Ed Greenwood built a new barn with an attached arena. To finance the loan, they paid $1,326 interest on $47,600 at 4%. What was the time, using exact interest? (Do not round intermediate calculations. Round up your answer to the nearest day.)

Step-by-step explanation

Note that

Interest is represented by I=1326

The principal is represented by P=47,600

Rate is R =4%

And Time is year

Interest is calculated using the formulae,

I =PRT/100

From the above formulae, time can be calculated as

T=100I/PR

T= 100×1326/(47600×4)

T= 132600/190400

T= 0.6964 years

To convert to days, multiply by 365(since those no of days make a year)

T= 0.6964×365=254 days

This was approximated to the nearest day

Answer is 254 days

acomoda 2 8 3 y 4 en este orden con las operaciones +-×÷ de forma que el resultado sea 76 y 40







Answers

Answer:

[(2*8) + 3] *4 = 76

[2*(8 - 3)]*4 = 40

Step-by-step explanation:

Los paréntesis ( ), corchetes [ ] y llaves {} son símbolos de agrupación que indican el orden de las cuatro operaciones aritméticas básicas (suma, resta, multiplicación y división). Las reglas del orden de operaciones establece que se debe realizar primero el cálculo dentro de los símbolos de agrupación.

En otras palabras, la jerarquía de operaciones es el orden en el que hay que realizar las distintas operaciones, ya que unas tienen prioridad frente a otras. Y establece primero debes empezar por resolver los paréntesis, luego los corchetes y finalmente las llaves. Es decir, cuando haya símbolos de agrupación dentro de símbolos de agrupación, calcula de adentro hacia afuera. Esto es, empieza simplificando los símbolos de agrupación en el centro.

Para obtener 76, se pueden realizar la siguiente operación combinada:

[(2*8) + 3] *4

Aplicando lo anteriormente mencionado de la jerarquía de operaciones, comienzas por resolver el paréntesis:

[16 + 3]*4

Ahora, resolviendo el corchete:

19*4

Finalmente, resolviendo la multiplicación:

19*4= 76

Entonces [(2*8) + 3] *4 =76

Para obtener 40, se pueden realizar la siguiente operación combinada:

[2*(8 - 3)]*4

Comenzando a resolver el paréntesis:

[2*5]*4

Ahora, resolviendo el corchete:

10*4

Finalmente, resolviendo la multiplicación:

10*4= 40

Entonces [2*(8 - 3)]*4 = 40

19c + 31 = 26c - 74




solve for c

Answers

Answer:c

c = - 15

Step-by-step explanation:

Simplifying

19c + 31 = 26c + -74

Reorder the terms:

31 + 19c = 26c + -74

Reorder the terms:

31 + 19c = -74 + 26c

Solving

31 + 19c = -74 + 26c

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add '-26c' to each side of the equation.

31 + 19c + -26c = -74 + 26c + -26c

Combine like terms: 19c + -26c = -7c

31 + -7c = -74 + 26c + -26c

Combine like terms: 26c + -26c = 0

31 + -7c = -74 + 0

31 + -7c = -74

Add '-31' to each side of the equation.

31 + -31 + -7c = -74 + -31

Combine like terms: 31 + -31 = 0

0 + -7c = -74 + -31

-7c = -74 + -31

Combine like terms: -74 + -31 = -105

-7c = -105

Divide each side by '-7'.

c = 15

Simplifying

c = - 15

During the first half of a football game, a running back ran for 9 total yards. In the second half, he ran for a loss of 12 yards. What was the running back's total yardage?

Answers

Answer:

21

Step-by-step explanation:

The running back's total yardage is 21 yards

From the question we are given the following parameters

Distance travelled in the first half of the game is 9 yards

Distance travelled in the second half of the game is 12 years

In order to determine the running back's total yardage, we will take the sum of the distance travelled as shown

Total distance travelled = 9 yards + 12 yards

Total distance travelled = 21 yards

Hence the running back's total yardage is 21 yards

The diagram shows a window in the shape of a square. Each side of the measures 8 √5 centimeters, and the area of the square is 32x square centimeters. What is the value of x?

Answers

Answer:

x = 10  

Step-by-step explanation:

recall that for a square with side length "L", the area of the square can be expressed as

Area = L x L

or

Area = L²

in this case we are given that Area, A = 32x

and that Side Length, L = 8√5

If we substitute these into the equation, we will get:

Area = L²

32x = (8√5)²   (using the properticals of exponents, we can re-write the right side)

32x = (8)² · (√5)²  

32x = 64 · 5

32x = 320   (divide both sides by 32)

x = 320 / 32

x = 10
