.
<u>Step-by-step explanation:</u>
Here we have , A customer at a store paid $64 for 3 large candles and 4 small candles. At the same store, a second customer paid $4 more than the first customer for 1 large candle and 8 small candles. The price of each large candle is the same, and the price of each small candle is the same. We need to find Which system of equations can be used to find the price in dollars of each large candle, x, and each small candle, y . Let's find out:
Let the price in dollars of each large candle, x, and each small candle, y .So
A customer at a store paid $64 for 3 large candles and 4 small candles
Equation is :
⇒ .....(1)

Answer:
Step-by-step explanation:
Given: In ΔGHI, =90°, IG = 6.8 feet, and HI = 2.6 feet
To find:
Solution:
Trigonometry defines relationship between the sides and angles of the triangle.
For any angle ,
= side opposite to
/side adjacent to
In ΔGHI,
Put
So,
Therefore,
F = 250
d = 50
workdone=Fd*cos()
=250*50*cos(
)
=12500*cos(
)=12378.35 joule
