Well, we can denote L and W for the length and width respectively. Lets say the A is the area, we have: 1. A=(L × W) as well as 2. 2(L+W)=400. We rearrange the second equation to get 3. W=200-L. From this, we can see that 0<L<200. Substitute the third equation into the first to get A=(200L-L²). put this formula into the scientific calculator and you will find a parabola with a maximum. That would be the maximum area of the enclosed area. Alternatively, we can say that L is between 0 and 200 when the area equals 0. (The graph you find will be area against length). As the maximum is generally found halfway, we substitute 100 into the equation and we end up with 10000.
Hope this helps.
So a box of 20 chocolates is divided between a group of people based on age
So the ratio for Sibusiso, Dorris, and Freddy is 2:3:5
Add these together, and you get 10
So to find how much each person gets, divide total amount of chocolates by total age
So (20÷10) = 2
So multiply each age term by 2 and you have your answer
(4:6:10)
So Sibusiso gets 4, Dorris gets 6 and Freddy gets 10
Answer:
17/20, 0.8, 75%
Step-by-step explanation:
17/20=85%, 0.8=80%
85% > 80% > 75%
Volume of piece candy is 113.04 cubic centimeter
<em><u>Solution:</u></em>
A student bought a piece of hard candy that is in the shape of a sphere
<em><u>The candy has a radius of 3 centimeters</u></em>
Radius = 3 cm
Use 3.14 for π
<em><u>Volume of sphere is given as:</u></em>
Where, "r" is the radius of sphere
<em><u>Therefore, volume of candy is given as:</u></em>
Thus volume of candy is 113.04 cubic centimeter
The nearest hundred would be 400
