Given:
total cost : 28.70
cost per pint of fruit : 2.85
Formula:
5v + 7f = 28.70
5v + 7(2.85) = 28.70
5v + 19.95 = 28.70
5v = 28.70 - 19.95
5v = 8.75
5v/5 = 8.75/5
v = 1.75 cost per pint of veggies.
to check:
v = 1.75 ; f = 2.85 ; total cost = 28.70
5v + 7f = 28.70
5(1.75) + 7(2.85) = 28.70
8.75 + 19.95 = 28.70
28.70 = 28.70

100 pinecones sold at $0.25 each is written as 100×.25 or one quarter of 100, which is 25.
Answer:
g(f(x) = 12x^2-2
Step-by-step explanation:
solution:
given,
f(x)=3x^2-1
g(x)=4x+2
g(f(x)=?
here,
g(f(x) = g(3x^2-1) [put the value of f(x) given]
=4(3x^2-1)+2 [ now put the value of g(x) and in the place of x put 3x^2-1]
=12x^2-4+2 [ by multiplying 4(3x^2-1) ]
= 12x^2-2 ans..
So g(f(x)=12x^2-2
hope its helps , I tried my best to explain there
hope you understand it as i am terrible at explaining like this ...
have a good time(•‿•)
Step-by-step explanation:
we use the law of sine :
a/sin(A) = b/sin(B) = c/sin(C)
a, b, c being the sides, A, B, C being the opposing angles of the sides.
and remember, the sum of all angles in a triangle is 180°.
so,
JL/sin(90) = KL/sin(72)
JL/1 = KL/sin(72)
KL = JL × sin(72) = 10 × 0.951056516... =
= 9.51056516... ≈ 10
JK/sin(L) = JL/sin(90) = JL
JK = JL × sin(L)
angle L = 180 - 90 - 72 = 18°
JK = JL × sin(18) = 10 × 0.309016994... =
= 3.09016994... ≈ 3
