Answer:
$90
Step-by-step explanation:
First the given is the listed price of DVD which is 120 dollars.
Now we need to find out what the price will be after discount of 25%
To do this we will have to convert the percentage to decimal by moving decimal 2 place left and removing percentage sign which will become 0.25.
Then we multiply by the listed price which is 120
so 120*0.25=30
so we subtract 30 by original price cause that is the discount off we are receiving
120-30=90
so 90 will be the sale price after 25% discount.
Sin and cos are related by the following identity:
sin (90 - θ) = cos(θ)
The value of θ in the given case is 48, so the equation becomes:
sin(90 - 48) = cos(48)
sin (42) = cos(48)
Thus, in the given question value of <span>ø will be 42 degrees.</span>
22 ( total) - 10 ( what she has already) = 12 ( the amount she needs to buy)
If 1 hair and = $1
Than 12 multiplied by $1 = $12
So she needs to spend $12 in order to have 22 hair bands
Answer:
Step-by-step explanation:
Both numbers of the ratio units used to express the ratio in ten years are 2 higher than at present. Thus, each ratio unit must stand for 5 years. That would make their current ages ...
Sunitha: 7·5 = 35
Raseeda: 8·5 = 40
_____
If you can't figure the answer right away from the change in ratio units, then you may need to write a couple of equations:
- s/r = 7/8
- (s+10)/(r+10) = 9/10
These can be translated to standard form, which may make some methods of solution easier:
These have solution (r, s) = (40, 35).
Range is the outputs possible
w(r(x))=(2-x^2)-2
w(r(x))=2-x^2-2
w(r(x))=-x^2
therefor the range is from 0 to -∞
