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.
Answer:
1. x = 30
2. x = 39
Step-by-step explanation:
1.
4x and ( 3x + 30 ) are alternate exterior angles,
Alternate exterior angles are equal.
4x = 3x + 30
4x - 3x = 30
x = 30
2.
x and ( 3x + 24 ) are co - interior angles.
Sum of co - interior angles is 180,
x + 3x + 24 = 180
4x + 24 = 180
4x = 180 - 24
4x = 156
x = 156 / 4
x = 39
Answer: I got 3.
Step-by-step explanation:
If a 12 gallon tank is filled with water at rate of 1/4 of the tank in 5 seconds, then it's filled with 3 gallons per 5 seconds (because 1/4 * 12 = 3). 5/6 of the tank is as much as 5/6 * 12 = 5 = 60/6 = 10 gallons.
If 3 gallons of the tank are filled in 5 seconds, then 10 gallons will be filled in (10 ÷ 3) * 5 = 3 1/3 * 5 = 16 2/3 seconds.
Answer: It will take 0 minutes and 16 2/3 seconds to fill 5/6 of the tank.
I hope that's what you meant :)
