Answer:

The money my sister have is $34

Step-by-step explanation:

Given as :

The two statements are as

If I give my sister 5 dollars, then we will have the same amount of money  ...A

If instead she gives me 8 dollars, then I'll have twice as much money as she has.      ......B

Let the money I have = $x

And The money my sister have = $y

Now, From statement A

x - 5 = y + 5

or, x - y = 5 + 5

or, x - y = 10          ........1

Again, From statement B

2 ×(y - 8) =  (x + 8)

2 y - 16 = x + 8  

2 y - x = 24         ........2

Now, solving Eq 1 and 2

Put the value of x from eq 1 into eq 2

2 y - (y + 10) = 24

Or, 2 y - y = 24 + 10

Or, y = 34

So, The money my sister have = y = $34

Put the value of y into eq 1

so, x - 34 = 10  

I.e x = 10 + 34

∴ x = 44

So, The money I have = x = $44

Hence, The money my sister have is $34 Answer

Find the cosine of ∠T.
Ostrovityanka [42]

ANSWER: ∠T = 32.4°

Remember the formula for the basic trig functions: SOH CAH TOA

Since you want to find cosine for <T, you need the adjacent side length as well as the hypotenuse's length which can be found using the Pythagoras's Theorem  a^2+b^2=c^2 with <em>a </em> and <em>b</em> being the side lengths and <em>c</em> being the hypotenuse.

Using the theorem, we get c=37

Now use the cosine formula to get <T = 12/37  to get the final answer.

The graph below shows the amount of money left in the school’s desk fund, f, after d desks have been purchased. A graph titled D
natima [27]

Answer:

$110

Step-by-step explanation:

The computation is shown below:

Provided that

Number of desk purchased    Fund Left $

           0                                   700

           1                                    590

           2                                   480

           3                                   370

           4                                   260

           5                                   150

           6                                    40

Now the Fund decreased while purchasing is

= 5 desks - 2 desks

= 3 desks

i.e

= $480 - $150

= $330

Now the amount of money left for decreased the desk fund is

= \frac{Fund\ decreased }{number\ of\ desk\ decreased}

= \frac{\$330}{3\ desk}

= $110
