Find the value of b that will make the equation sin 62°= cos B true when 0°
KiRa [710]

Hello from MrBillDoesMath!

Answer:

b = 28 degrees

Discussion:

In general,

sin (90 - @) = cos(@)

Set 90 [email protected] = 62  => @ = 28 so

sin (90-28) = sin(62) = cos(28)    => b = 28

Thank you,

MrB

Coles has cut the price of Cadbury's chocolate bars by 20%. Their normal price is $3.45. A shareholder who has a Coles-Myer disc
pickupchik [31]
The first discounted price is given through the equation,
                              discounted price = ($3.45)(1 - 0.20) = $2.76
Then, due to the privilege of being a Coles-Myer discount card holder, another 7.5% discount is given. Such that the final price would be,
                              final price = ($2.76)(1 - 0.075) = $2.553
The total amount saved up is equal to,
                                    $3.45 - $2.553 = $0.897

Black_prince [1.1K]

Answer:

The\ weight\ of\ the\ 50\ erasers\ be\ \frac{4000}{n}\ grams.

Step-by-step explanation:

As given

if n erasers have a weight of 80 grams .

I.e

n erasera =  80 grams.

1 erasers weight .

1\ erasers\ weight = \frac{80}{n}

Now find out the weight of the 50 erasers.

Weight\ of\ 50\ erasers = \frac{50\times 80}{n}\ grams

Simplify the above

Weight\ of\ 50\ erasers = \frac{4000}{n}\ grams

Therefore\ the\ weight\ of\ the\ 50\ erasers\ be\ \frac{4000}{n}\ grams.
