Length to width is : 20:15 which reduces to 4:3 or 4/3 or 4 to 3
Answer:
Positive
Step-by-step explanation:
If you look at the plot you can see as the population goes up the years go up as well, so you can tell that they are positive since they go from left to right up.
Hope this helps :)
Answer:
120º
Step-by-step explanation:
First we need to know the fraction of the area of ORT to the area of the circle.
Fraction = 18π/54π = 1/3
We know that a circle is 360º, and sector ORT is xº. The fraction of the sector of ORT to the circle must also be equal to 1/3.
x/360 = 1/3
3x = 360
x = 120º
Try this solution:
1. The final formula for the area of the figure is: A=A₁+A₂, where A₁ - the area of the square (its side is 18m) and A₂ - area of the triangle (the base is (8+18)m., height is 16 m.)
2. Using all the data in the formula above:
A=18*18+0.5*16*(8+18)=324+8*26=324+208=532 m².
answer: 532
