1 pack has 5 seperate packs, each with 10 pieces
=>50 pieces
50*3=150 pieces of gum
Answer:
1. 37
2. 26
3. 26
Step-by-step explanation:
Subtracting 63 from 180, you find the linear pair, being 117 which helps find an angle in the lower triangle. The sum of all angles is 180, and to find 2, you subtract the known angles ( 180-(37+117)) which equals 26. Knowing the shape is a parallelogram, and the opposite sides are parallel, we can say 2 and 3 are congruent through the alternate interior angles theorem. 1 is found through applying the same theorem.
X = larger number
x-1 = smaller number
x*(x-1)=5+3x
x^2-4x-5=0 use the formula
x=5
x-1=4
the 2 numbers are 5&4 or -1,-2
Answer:
227.75 cm
Step-by-step explanation:
a coin (Circle) with diameter 2.9cm
(radius) r = diameter ÷ 2
r = 2.9cm ÷ 2
r = 1.45cm
1 complete revolutions (perimeter or circumference of a circle ) = 2πr
= 2 × π × r
where r = radius, π is a constant = 22/7
= 2 × 22/7 × 1.45
= 9.11cm
thus in one complete revolution the coin travels a distance of 9.11cm.
therefore in 25 complete revolutions the coin will travel a distance of = 25 × 9.11 cm = 227.75 cm.
The distance covered in complete 25 revolutions of a coin with diameter of 2.9 when it's rolled is = 227.75 cm
