first box - $2.90 per pound
second- $2.50 per pound
third- $2.98 per pound
fourth- $2.00 per pound
Answer:
4 hours
Step-by-step explanation:
set up your equation
money to spend = charge per hour
18 = 4.50x
divide each side by 4.50
x = 4
4 hours
Given that Macy wants to construct an isosceles triangle, with the unique angle being 40° it implies that for the triangle to be isosceles, the base angles should be the same. The size of the base angles will be:
(180-40)/2=70
given that that the base is 6 cm, Macy can only form 1 triangle with these dimensions.
The length of the other sides will be found using sine rule
a/sin A=b/sin B
a=6 cm
A=40°
b=?
B=70
hence:
6/sin 40=b/sin 70
b=(6sin 70)/sin40
b=8.77 cm
X= 75
the equation is
is/of %/100
48 = is
64 = %
X = of
100 = 100
48 X 100 = 4,800
64 X x = 64x
64x / 64 = x
4800 / 64 = 75
