Answer:
Step-by-step explanation:
Given
Represent the weight of the Jar with J and the sugar with S
Initially, we have:
After 2/3 of sugar is removed we have:
Required
Determine the weight of the jar
--- (1)
--- (2)
Simplify (2)
Take LCM
Make S the subject in (1)
Substitute 850g - J for S in
Multiply through by 3
Collect Like Terms
Make J the subject
<em>The jar weighs 370g</em>
The top surface area of the wedge with central angle of π / 2 radian is 9π / 4 inches square
<h3>How to find area of a sector?</h3>
The area of the top surface of the the wedge is the area of a sector.
Therefore,
area of the top surface = ∅r² / 2
area of the top surface = π / 2 × 3² × 1 / 2
area of the top surface = π / 2 × 9 × 1 / 2
area of the top surface = 9π / 4
area of the top surface = 9π / 4
area of the top surface = 9π / 4 inches squared

I know these numbers from a triangle because 24+30=54 and 6square root 43 is about 39
The first one is 9/16 you have to make 54 and 96 a fraction such as 54/96 then simplify
the second one is 1/5 you have to make 4 and 20 a fraction like this 4/20 then simplify
hope this helps!!
Answer:
t= 03:21 h
Step-by-step explanation:
A constant speed means that it does not change over a period of time and direction of motion. A simple formula, for this case (constant speed)
where x is distance and t time. The subtract is final value minus initial value
If xo=0 miles and to=0 h, then
We have distance, and speed so we need to calculate the time (how long)
t= 03:21 h
