Answer:
Chocolate cones = x = 167 cones
Vanilla cones = y = 334 cones
Step-by-step explanation:
Let
The number of Chocolate cones = x
Vanilla cones = y
Ike's igloo sold 501 ice cream cones today.
x + y = 501.... Equation 1
They sold half as many chocolate ice cream cone as vanilla ones.
x = 1/2y
x = y/2
Cross multiply
y = 2x
We substitute 2x for y in Equation 1
x + 2x = 501
3x = 501
x = 501/3
x = 167
Solving for y
y = 2x
y = 2 × 167
y = 334
Therefore,
The number of
Chocolate cones = x = 167 cones
Vanilla cones = y = 334 cones
He score 48 marks.
This can be found by simply multiplying 80 by 60% (0.6). This will give you your rinal answer of 48.
I hope this helps!
Answer:
decimal?????
Step-by-step explanation:
Answer:
(I)Sin Θ=4/5
(II) Cos Θ =-3/5
(III) Tan Θ = -4/3
(IV) Cosec Θ = 5/4
(V) Sec Θ = -5/3
(VI) Cot Θ = -3/4
Step-by-step explanation:
(-24,18)
This lies in the second quadrant from the diagram.
Note that the angle is at the origin (0,0).
Using Pythagoras triples(18,24,30)
Hypotenuse = 30
Opposite=-24
Adjacent=18
(I)Sin Θ= Opposite/Hypotenuse
=-24/30=-4/5
Note: (Sine is Positive in the Second Quadrant)
Sin Θ =4/5
(II) Cos Θ = Adjacent/Hypotenuse
=18/30=3/5
Since Cosine is negative in the Second Quadrant
Cos Θ=-3/5
(III) Tan Θ = Opposite/Adjacent
Tan Θ = -24/18= -4/3
(IV) Cosec Θ = 1/Sin Θ = 5/4
(V) Sec Θ = 1/cos Θ = -5/4
(VI) Cot Θ = 1/tan Θ = -3/4
