Answer:
X = 18
Y = 9√3
Step-by-step explanation:
use sin equation for right angle triangle
The sine of the angle
= ( the length of the opposite side ÷ the length of the hypotenuse.)
according to this question,
sin 30 = 9 / X
1/2 = 9 / X
X = 18
use cosine to find y
The cosine of the angle
= (the length of the adjacent side ÷ the length of the hypotenuse.)
cos 30 = y/x
√3/2 = y/ 18
y = 9 ✓3
Answer:
It didn’t go up, it went down 3 degrees
Step-by-step explanation:
It’s negative degrees so the less negative it is the higher it is.
3.5 , 7 , 10.5 , 14 , 17.5 , 21 , 24.5 . Because it increases by 3.5 each time
For set of dishes,price of discount =10%of $35.66=$3.566
Cost price of set of dishes = $35.66
Selling price of set of dishes =$35.66-$3.566
=$32.094
Cost price of towel=$21.56
Price of coupon =$2.75
Selling price after using coupon =$21.56-$2.75= $18.81
Cost price of candle =$9.02
Price of coupon=$0.50
Selling price of candle after using coupon =$9.02 -$0.50 =$8.52
Therefore the answer is D since she saved the greatest percentage on the set of dishes
Answer:
Step-by-step explanation:
The pasta plate will cost $ 5.5
y=4x+2.5 ( x is the number of ingredients)
$ 2.5+(4*0.75)= 5.5 dollars
