Here, a = 3/4, d = 1 - 3/4 = 1/4, n = 13
a(n) =  a + ( n - 1)d
a(n) = 3/4 + (13-1)1/4
a(n) = 3/4 + 12/4
a(n) = 3/4 + 3
a(n) = 15/4
a(n) = 3 3/4

In short, Your Answer would be Option D

Hope this helps!

There are two spinners. Each spinner has 10 equal sectors labeled with the numbers 1 through 10.
Reika [66]

Answer: Second option is correct.

Step-by-step explanation:

Since we have two spinners,

Each spinner has 10 equal sectors labeled with the numbers from 1 to 10.

Primes numbers from 1 to 10 is given by

\{2,3,5,7\}

So, number of outcomes shows a  primes number from 1 to 10 = 4

Similarly ,

Composite numbers from 1 to 10 is given by

\{4,6,8,9,10\}

So, number of outcomes shows a composite number from 1 to 10 =5

∴ Total outcomes show a prime number on the first spinner and a composite number on the second spinner is given by

4\times 5=20\\

Thus, Second option is correct.

The amount of $15,000 is invested in two funds paying 2% and 5% simple interest. If the annual interest is $540, how much of the
Lostsunrise [7]

Answer:

The amount $15000 is divided as

in 2% = $7000

in 5% = $8000

Step-by-step explanation:

It is given that the total amount is $15000 and rates of interests are 2% and 5%.

<em>Let the amount invested in 2% be "x", so the amount invested in 5% is (15000 - x).</em>

The annual interest on x part is given as,

= (\frac{2}{100})(x)

Similarly, The annual interest on (15000 - x) part is given as,

=  (\frac{5}{100})(15000 - x)

the total annual interest is given as $540

Thus, <em>540 = (\frac{5}{100})(15000 - x) + (\frac{2}{100})(x)</em>

<em>54000 = 2(x) + 75000 - 5(x)</em>

<em>21000 = 3(x)</em>

x = \frac{21000}{3} = 7000

Thus the shares are $7000 and (15000 - 7000) $8000 .

Write the slope-intercept equation of the line passing through (-2,-5) with a slope of 0
frutty [35]
We want to find the slope-intercept equation of the line passing through (-2,-5) with a slope of 0.

Note that since the slope is 0, the line will be horizontal, as there will be no change.

And since it passes through the point (-2,-5), the equation of the horizontal line must be y = -5. Since the line is horizontal, the x-coordinate is irrelevant.

In conclusion, our equation is y = -5.
