Answer:

the cost each of one cherry pie and one lemon meringue pie is 9 and $12 respectively

Step-by-step explanation:

The computation of the cost of one cherry pie and the lemon meringue pie is shown below:

Let us assume the cherry pie be x

And, the lemon meringue pie be y

So according to the question

x + 5y = $69

5x + 7y = $129

Now multiply by 5 in the equation 1

5x + 25y = $345

5x + 7y = $129

18y = $216

y = $12

And, x would be

x + 5($12) = $69

x = $9

Hence, the cost each of one cherry pie and one lemon meringue pie is 9 and $12 respectively

Answer:

n = 11°

⠀

Step-by-step explanation:

When two straight lines intersect each other, then the pairs of angles so formed without any common arm are called vertically opposite angles.

Vertically opposite angles are equal to each other.

⠀

So,

${\longrightarrow \it\qquad { \ { (6n - 4) {}^{ \circ} = {(5n + 7)}^{ \circ} }}}$

⠀

Removing the brackets,

${\longrightarrow \it\qquad { \ { 6n - 4{}^{ \circ} = {5n + 7 \: }^{ \circ} }}}$

${\longrightarrow \it\qquad { \ { 6n - 5n = { 7 \: }^{ \circ} +4{}^{ \circ} }}}$

${\longrightarrow \it\qquad { \pmb{ n = { 11 \: }^{ \circ} }}}$

⠀

Therefore,

The value of n is 11°

When plucked, the high E string on a guitar has a frequency of 330 cycles per second. What sine function represents this note wh

Ber [7]

Let's analyse the function

$y = f(x) = A\sin(\omega x)$

The amplitude is A, so we want A=1.5

Now, we start at x=0, and we have $1.5\sin(0)=0$

After one second, i.e. x=1, we want this sine function to make 330 cycles, i.e. the argument must be $330\cdot 2\pi$

So, we have

$f(1)=1.5\sin(\omega) = 1.5\sin(660\pi)$

so, the function is

$f(x) = 1.5\sin(660\pi x)$
