15% of 425
(15/100) * 425
(3/20) * 425
(3/4) * 85
255 / 4
63.75

The answer is 63.75

How i got this is first you need to turn 15% into a decimal to do that you need to move the decimal from the hundrith place or the second number which in this case it would be 5 in the 15%

Now that you know the decimal all thats left to do is to just multiply .15 to <span>£425

</span>£425x.15= £63.75 <--- 15% of <span>£425</span>

stira [4]

Answer:

10000

Step-by-step explanation:

there is a simple formula to remember.

the sum of n odd number = n^2

so for the sum of 100 positive odd numbers = (100)^2=10000

You multiply 6.5 *4 =26 then you multiply 26 *6= 156 so that's $156.00.

Help!! Answer !!! about to run out of time in test!!

Gemiola [76]

$\qquad \qquad\huge \underline{\boxed{\sf Answer}}$

Here's the solution ~

Let's find the measure of hypotenuse first, by using Pythagoras theorem ;

$\qquad \sf \dashrightarrow \: h {}^{2} = {8}^{2} + {6}^{2}$

$\qquad \sf \dashrightarrow \: h {}^{2} = {36}^{} + {64}^{}$

$\qquad \sf \dashrightarrow \: h {}^{2} = 100$

$\qquad \sf \dashrightarrow \: h {}^{} = \sqrt{100}$

$\qquad \sf \dashrightarrow \: h {}^{} = {10}$

Now, let's find the asked values ~

$\qquad \sf \dashrightarrow \: \sin(x) = \dfrac{opposite \: side}{hypotenuse}$

$\qquad \sf \dashrightarrow \: \sin(x) = \dfrac{6}{10}$

$\qquad \sf \dashrightarrow \: \sin(x) = \dfrac{3}{5} \: or \: 0.6 \: units$

For Cos y :

$\qquad \sf \dashrightarrow \: \cos(y) = \dfrac{adjcant \: side}{hypotenuse}$

$\qquad \sf \dashrightarrow \: \cos(y) = \dfrac{6}{10}$

$\qquad \sf \dashrightarrow \: \cos(y) = \dfrac{3}{5} \: or \: 0.6 \: units$

As we can see that both sin x and Cos y have equal values, therefore The required relationships is equality.

I.e Sin x = Cos y

Hope it helps ~
