The sum of 2 numbers is 41. if we call the smaller number x then the other number is 41-x.
41-x=2x-1
42=3x
x=14
41-14 is 27
the two numbers are 14 and 27

Lerok [7]
The picture in the attached figure

we know that
in the right triangle ABC
sin A=opposite side angle A/hypotenuse

in this problem
opposite side angle A=BC-----> 10
hypotenuse=AB-----> 26
so
sin A=10/36------> sin A=0.3846------> sin A=0.385

the answer is
the option <span>d. 0.385</span>

Which formula can be used to describe the sequence <br> -3, 3/5, -3/25, 3/125, -3/625
maks197457 [2]

Answer:

a(n) = -3(-1/5)^(n - 1)

Step-by-step explanation:

From the first term, -3, we get the second term, 3/5, by multiplying -3 by -1/5.

Thus, the common ratio is -1/5.

The general formula in this case is a(n)=(first term)(common ratio)^(n - 1), or

a(n) = -3(-1/5)^(n - 1)

The function C(x) = 49.5x + 19.5 represents the cost (in dollars) of buying x concert tickets. How much does it cost to buy four
Reika [66]
To buy four tickets it would cost $217.5 because
C(x) = 49.5(4) +19.5
C(x) = 198 +19.5
C(x) = 217.5
With $465 you could buy 9 tickets.
C(x) = 49.5(9) +19.5
C(x) = 445.5 + 19.5
C(x) = 465

Ruby buys 24 books and 5 pens.she pays with a 500 rupee note and get rs90 as change.shania bought 12 books and 10 pens for rs280
just olya [345]

The cost of one pen is Rs 15.

<h3>How to find the cost of one pen?</h3>

It is given that Ruby paid with a 500 rupee note and got Rs 90 back.

This means that she spent 410 rupees.

Therefore the cost of 24 books and 5 pens is Rs 410.

Let the cost of books be x and the cost of pens be y.

Therefore, we can form the following equations:

24x + 5y = 410                   (1)

12x + 10y = 280                   (2)

We have to find the value of y.

Multiply the second equation by 2:

24x + 20y = 560                   (3)

Now subtract the first equation from the third equation:

24x + 20y - 24x - 5y = 560 - 410

15y = 150

y = 15.

The variable y represents the cost of one pen.

This means that the cost of one pen is Rs 15.

Therefore, we have found that the cost of one pen is Rs 15.
