Answer:
see explanation
Step-by-step explanation:
(a)
OC = OB ( both radii of the circle )
Thus Δ BOC is isosceles with congruent base angles.
∠ BOC = ∠ BCO = 50°
(b)
∠ ACB = 90° ( angle in a semicircle ), then
∠ ACO = 90° - 50° = 40°
OA = OC ( both radii of the circle )
Thus Δ ACO is isosceles with congruent base angles.
∠ BAC = ∠ ACO = 40°
Answer:
3.8 ; 3.79 ; 3
Step-by-step explanation:
Given that:
1 gallon is equal to about 3.785 litres
3.785 to the nearest tenth :
Tenth digit = 7 ; round up 8 to 1 and add to 7
Hence,
3.785 = 3.8 (nearest tenth)
3.785 to the nearest hundredth :
Hundredth digit = 8 ; round up next digit 5 to 1 and add to 8
3.785 = 3.79 ( nearest hundredth)
What is the greatest number of whole liters of water you could pour into a one-gallon container without it overflowing?
The greatest Number of whole liters of water that could be poured into a 1 gallon container without it overflowing is 3 liters because, rounding up 3.785 to the nearest integer of 4 means we will exceed the maximum litres by about 0.215 gallons and hence, cause the container to overflow.
10^3= 1,000
hope this helps :)
The slope of the line is 4/1.
An easy way to find the slope of a line is something called "rise-over-run." From the lowest point, how many spaces does it have to move up in order to be horizontally-on-the-line with the highest point? 4.
How many spaces across? 1...
4 = rise
1 = run
4 RISE
-- -------
1 RUN
