nalin [4]

Answer:

$160

Step-by-step explanation:

El monto total a pagar es de $350

\dfrac{1}{7} es pagado por mamá

\dfrac{2}{5} es pagado por el hermano mayor

La porción pagada por papá es

1-(\dfrac{1}{7}+\dfrac{2}{5})=1-(\dfrac{5+14}{35})\\ =1-\dfrac{19}{35}\\ =\dfrac{35-19}{35}\\ =\dfrac{16}{35}

Esta cantidad pagada por papá es

350\times\dfrac{16}{35}\\ =10\times 16\\ =\$160

Esta cantidad pagada por papá es $160.

29. March sales accounted for 1/7 of the total number of jazz records sold all year. About how many jazz records were sold all y
enot [183]

The March sales of Jazz records is an illustration of proportions, and the number of jazz records sold all year is 7x

<h3>How to determine the total number of sales?</h3>

The sales in March is given as:

Proportion = 1/7

Let the actual number of sales in the month of March be x, and the total sales in the year be y.

So, we have:

1/7 * y = x

Make y the subject

y =7x

Hence, the number of jazz records sold all year is 7x

Someone please help.

Hi there!

f(x)+f(x+1)=4f(x)

There are 3 parts to this equation:

f(x)

f(x+1)

4f(x)

We must first determine these three parts separately.

<u>1) f(x)</u>

We're given that  f(x)=3^x:

⇒ f(x)=3^x:

<u>2) f(x+1)</u>

Now, we must find f(x+1). To do so, add 1 to x in the original function f(x)=3^x:

⇒ f(x+1)=3^x^+^1

<u>3) 4f(x)</u>

To find 4f(x), multiply the original function f(x)=3^x by 4:

4f(x)=4*3^x:

<u>4) Put it all together</u>

Now, plug each of the three parts into the equation f(x)+f(x+1)=4f(x):

f(x)+f(x+1)=4f(x)

3^x+3^x^+^1=4*3^x\\3^x+3^x*3=4*3^x

Factor the left side

3^x*(1+3)=4*3^x

Divide both sides by 3^x

1+3=4\\4=4

Because this equation is true, f(x)+f(x+1)=4f(x) is therefore true.

I hope this helps!

A customer borrowed 2000 and then further 1000 both repayable in 12 months .What would he have saved if he had taken out one loa
creativ13 [48]

Answer:

No savings

Step-by-step explanation:

Let the interest rate be same for all the loans and consider it to be R.

<u>First case</u>

Principal 1 = 2000

Time = 12 moths = \frac{12}{12} = 1 year

Rate = R %

So, interest 1 = Principal * Time * Rate

                   = 2000 * 1 * R

                   = 2000R

Now,

Principal 2 = 1000

Time = 12 moths = \frac{12}{12} = 1 year

Rate = R %

So, interest 2 = Principal * Time * Rate

                   = 1000 * 1 * R

                   = 1000R

Total interest to be paid = 2000R + 1000R

                                         = 3000R

<u>Second case</u>

Principal = 3000

Time = 12 moths = \frac{12}{12} = 1 year

Rate = R %

Interest = Principal * Time * Rate

             = 3000 * 1 * R

             = 3000R

We conclude that there would be no savings because the interest to be paid in both the cases are same.
