Answer:
The number of candles each girl needs to sell so that the total amount raised is the same for both is
<em>Hailey </em>70 candles
<em>Kacie </em>40 candles
Step-by-step explanation:
Let
x------> the number of candles sold
y----> total amount raised
we know that
<em>Hailey's equation</em>
-----> equation A
Please note that Hailey has already raised $160, so he has sold 40 candles.
<em>Kacie's equation</em>
-----> equation B
Please note that Kacie has already raised $70, so he has sold 10 candles.
equate equation A and equation B solve for x
The number of candles each girl needs to sell so that the total amount raised is the same for both is
<em>Hailey</em>
40+30=70 candles
<em>Kacie</em>
10+30=40 candles
Answer:
Step-by-step explanation: the first number goes two the side and the secend goes up
1/4(365) = 365/4 oz = 365/4(16) pound = 365/64 pound
Answer:
28.07° ; 70.53° ; 53.13° ; 36.87°
Step-by-step explanation:
Using PYTHAGORAS RULE :
IMAGE 1:
value of cos α equals :
cos α = Adjacent / Hypotenus
cos α = 15 / 17
cos α = 0.88235
α = cos^-1 (0.88235)
α = 28.07°
IMAGE 2:
sin β = Opposite / Hypotenus
sin β = 14√2 / 21
sin β = 0.9428
β = sin^-1(0.9428)
β = 70.53°
IMAGE 3:
From trigonometry :
cot = 1 / tan
Tan = Opposite / Adjacent
Therefore, Cot = Adjacent / Opposite
cot γ = 3/4
cot γ = 0.75
γ = cot^-1 (0.75)
γ = 53.13°
IMAGE 4:
tan α = Opposite / Adjacent
tan α = 15 / 20
tan α = 0.75
α = tan^-1 (0.75)
α = 36.87°
