Given parameters:
Length of earring hook = 1.5cm
Length of given wire = 45cm
Dimension of the triangle = 3.2cm, 3.2cm and 2.1cm
Unknown:
Number of earrings that can be made from the wire = ?
To solve this problem, we need to calculate the total length of the earring we want to make.
Total earring length = Perimeter of earring + length of earring hook
= 3.2 + 3.2 + 2.1 + 1.5
= 10cm
Now the length of the wire is 45cm,
Number of earrings =
= 4.5 earrings
But this is not reasonable, therefore, we can only forge 4 complete earrings from the given length with 5cm of wire remaining.
The number of earrings that can be made is 4.
I would have to say 2.3 but i dont know the real answer thats what i calculated
Answer:
40 mph.
Step-by-step explanation:
Hope I helped!
x-5=speed of car B
x=speed of car A
distance=speed times time
(x-5)(4.5)=(x)(4)
4.5x-22.5=4x
Multiply both sides by 2 to get rid of the decimals.
9x-45=8x
Subtract 8x from each side.
x-45=0 9 (A)
Add 45 to both sides.
x=45
Speed of car A=45 mph
Speed of car B=40 mph
The answer is B. The product of two irrational numbers
