When Jennifer and Tom visit another country, they find two types of coins are used there, one with a Q on it and one with an E on it. Jennifer has 13 Q coins and Tom has 5 Q coins and 7 E coins. If Jennifer's coins have a total value of $0.65 and Tom's coins have a total value of $3.75, what is the value of each type of coin?

Answers

Answer 1

Answer:

q = $0.05

e = $0.5

Step-by-step explanation:

13q = 0.65 equation 1

5q + 7e = $3.75   equation 2

in equation 1, divide both sides of the equation by 13

q = 0.65 / 13 = 0.05

Substitute for the value of q in equation 2

5(0.05) + 7e = 3.75

0.25 + 7e = 3.75

collect like terms

3,75 - 0.25 = 7e

3.5 = 7e

e = 0.5

The Estrada family has established for cable internet service since the pandemic. When establishing the service, there was an initial fee as well as a monthly fee on the contract. c(m)=35m+40 represents this scenario. How much has the Estrada family paid for internet service if they began service in March 2020?​

Answers

Given:

When establishing the internet service, there was an initial fee as well as a monthly fee on the contract.

The given function is:

[tex]c(m)=35m+40[/tex]

To find:

The cost of internet service if they began service in March 2020.

Solution:

We have,

[tex]c(m)=35m+40[/tex]

We need to find the internet service cost for the first month. So, substitute [tex]m=1[/tex] in the given function.

[tex]c(1)=35(1)+40[/tex]

[tex]c(1)=35+40[/tex]

[tex]c(1)=75[/tex]

Therefore, the cost of internet service is 75 if they began the service in March 2020.

Answer:

m<CAO = 56

Step-by-step explanation:

When two parallel lines are intersected by a transversal, the same-side interior angles are supplementary, meaning that their angle measures add up to (180) degrees. Using this information, substitute in the given values and solve for the unknown,

(m<DOA) + (m<CAO) = 180

Substitute,

3x + 40 + 2x = 180

Simplify,

5x + 40 = 180

Inverse operations,

5x + 40 = 180

     -40    -40

5x = 140

/5     /5

x = 28

Now substitute the value of (x) back into the given expression for the value of (<CAO). Solve to find the numerical value.

<CAO = (2x)

= 2(28)

= 56

Si un capital de 6800 soles se presta a 12% anual, durante a años y 19 días, ¿Qué interés producirá?

Answers

El número de años no se da de forma exhaustiva. Usando un valor hipotético

Respuesta:

Por favor, consulte la explicación.

Explicación paso a paso:

Suponga que el número de años es igual a 1 año 19 días

Convertir en años; 19 días es igual a 19/365 = 0,0520547; por lo tanto, 1 + 0.0520547 = 1.0520547 años

Recuerde la fórmula de interés simple:

Interés = principal * tasa * tiempo

Interés = 6800 * 0,12 * 1,0520547

Intereses = 858,4766352

Por tanto, si el plazo es de 1 año 19 días; interés = 858.4766352

Si el número de años en el período es diferente, simplemente siga el mismo paso para convertir los días y sume al número exacto si los años se dan.

Yasmine's Mom had to buy 9 pints of ice cream and each pint cost $2.73 (tax is included in that cost). How much did the 9 pints of ice cream cost? If she paid for the ice cream with $40, how much money did she get back?

Answers

Answer:

$24.57

$15.43

Step-by-step explanation:

Cost per pint of ice cream = $2.73

Number of pints purchased = 9

Total cost = cost per pint * Number of pints

Total cost = $2.73 * 9 = $24.57

If she paid $40

Change collected = $40 - $24.57 = $15.43
