ANSWER
Options B, C and D have exactly 2 significant figures.
<u>EXPLANATION</u>
To see whether the numbers have exactly 2 significant figures, round all to 2 significant figures. The ones that remains the same have exactly 2 significant figures.
yards to 2.s.f
gallons to 2.s.f
feet to 2.s.f
litters to 2.s.f\
meters to 2.s.f
Answer : The amount of margarine needed is 1 kg.
Step-by-step explanation :
First we have to convert volume of syrup from mL to L.
Conversion used:
1 L = 1000 mL
or, 1 mL = 0.001 L
So, 225 mL = 0.225 L
Now we have to calculate the amount of margarine needed.
As, 0.225 L of syrup needed 150 g of margarine
So, 1.8 L of syrup needed of margarine
Amount of margarine needed = 1000 g = 1 kg (1 kg = 1000 g)
Therefore, the amount of margarine needed is 1 kg.
The perpendicular bisector theorem gives the statements that ensures
that and
are perpendicular.
The two statements if true that guarantee is perpendicular to line
are;
Reasons:
The given diagram is the construction of the line perpendicular to line
.
Required:
The two statements that guarantee that is perpendicular to line
.
Solution:
From the point <em>C</em> arcs <em>E</em> and <em>D</em> are drawn to cross line , therefore;
arcs drawn from the same radius.
is perpendicular to line
, given.
Therefore;
