Answer:
38.13 m^2
Step-by-step explanation:
the area of a triangle =b*h/2
b=base
h=height
area triangle=(4m*3m)/2=(12m^2)/2=6m^2
the area of a rectangle =b*h
b=base
h=height
area of a rectangle=6m*3m=18m^2
area of a semi circle=(pi*r^2)/2
r=radius
area of a semi circle==(3.14*(3m)^2)/2=14.13m^2
area of the figure=6m^2+18m^2+14.13m^2=38.13m^2
the answer is 38.13m^2
Y=-7/2x+1/2
i already typed the work out but something went wrong?
1. find slope
2. plug in slope to slope intercept form equation
3. plug in a point to find b
4. plug in slope, b to get equation
Answer:
18%
Step-by-step explanation:
9 over 50 equals 18 over 100, 18 over a hundred equals 18 percent
The correct proportions are given as follows:
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The proportions for this problem are given dividing y by x, hence:
- x = 3, y = 27: 27/3 = 9, hence 9/1 has to be marked.
- x = 9, y = 81: 81/9 = 9, hence 9/1 has to be marked.
- x = 21, y = 126: 126/6 = 6, hence 6/1 has to be marked.
- x = 14, y = 84: 84/14 = 6, hence 6/1 has to be marked.
- x = 12, y = 36: 36/12 = 3, hence 3/1 has to be marked.
- x = 15, y = 45: 45/15 = 3, hence 3/1 has to be marked.
