H = 0.75n is the expression as a product to represent the sale price of the shirt
<em><u>Solution:</u></em>
Given that, Miranda buys a shirt at the mall
She has a coupon for 25 % off
To find: Expression as a product to represent the sale price of the shirt
Let "H" be the sale price of shirt
Let "n" be the original price of shirt
From given statement,
discount = 25 % of original price
Therefore,
discount = 25 % of n
<em><u>The sale price is given as:</u></em>
<h3>Sale price = Original price - discount price</h3>
H = n - 0.25n
<h3>H = 0.75n</h3>
Thus expression as a product to represent the sale price of the shirt is found
Answer:
12
Step-by-step explanation:
7x+10=94
-10 -10
7x=84
7x/7=84/7
x=12
4x-6=42
+6 +6
4x=48
4x/4=48/4
x=12
Answer:
sin(A+B) = 297/425
Step-by-step explanation:
This problem involves a couple of Pythagorean triples, and the trig identity for the sine of the sum of angles.
The Pythagorean triples involved are {8, 15, 17} and {7, 24, 25}. These tell us the other trig functions of the given angles:
sin(A) = 8/17 ⇔ cos(A) = 15/17
cos(B) = 24/25 ⇔ sin(B) = 7/25
The trig identity we're using is ...
sin(A+B) = sin(A)cos(B) +cos(A)sin(B)
sin(A+B) = (8/17)(24/25) +(15/17)(7/25)
_____
<em>Check</em>
A = arcsin(8/17) ≈ 28.072°
B = arccos(24/25) ≈ 16.260°
sin(A+B) = sin(44.332°) ≈ 0.6988235
sin(A+B) = 297/425
