SinA = 3/5
cosA = 4/5
cosB = 3/5
sinB = 4/5
sin(A+B) = sinAcosB + cosAsinB
= (3/5)(3/5) + (4/5)(4/5)
= 9/25 + 16/25
=(9+16)/25
=25/25
=1
therefore, the answer is B
Answer:
<em>The tax is $1.54 and the price after tax is $31.54</em>
Step-by-step explanation:
<u>Percentages</u>
The procedure to add a percentage ratio p to a given quantity q is:
* Calculate the increase as i = p*q/100
* Add the increase to the original quantity to get the final quantity f=q + i
It's given the sales tax rate in New Mexico is p=5.125%. A pair of pants in New Mexico costs q=$30 before tax.
* The increase (tax) is i = (5.125*30)/100 = $1.54
* The price after tax is f = $30 + $1.54 = $31.54
The tax is $1.54 and the price after tax is $31.54
Answer:
9.33
Step-by-step explanation:
5 x 90 = 450
When you multiply numbers with zeros, you first multiply the numbers and then add the zero(es) at the end.
5 x 9 = 45
5 x 90 = 450
