Out of the four options,
A. 99 cm B. 105.98 cm C. 90 cm D. 104.5 cm,
option A is the correct answer.
Because 1 m = 100 cm and this is the nearest approximation. Thus, the<span>A student used A tape measures to estimate the length of a meterstick manufactured to he exactly 1 meter. </span>

not sure if that is 100% correct
Answer:
BC=25
Step-by-step explanation:
this is an isosceles triangle, so sides AB and sides AC are equal
AB = AC
4x+1 = 2x+23
subtract 2x from each side
2x+1 = 23
subtract 1 from each side
2x =22
divide by 2 on each side
x =11
BC = 3x-8
substitute the value of x
BC = 3*11 -8
BC = 33 -8
BC=25
It is in form
0=ax^2+bx+c
0=-3x^2-2x+6
a=-3
b=-2
c=6
so

Jacob used 1/7 of a liter
of water.
He needs to fill 1/9 of the fish aquarium.
Find how many liters would Jacob need to fill the aquarium
=> Let x = liters of water need to fill the aquarium
=> x/1 = 1/7 divided by 1/9
=> x = 1/7 x 9/1
=> x = 9/7, since this is an improper fraction, let’s convert it to
mixed fraction
=> x = 1 and 2/7
So, Jacob need 1 and 2/7 liter of water to fill the whole aquarium.
