5/20 students in Alessandro's class live in Oakdale, which can be simplified to 1/4. 1/4 in decimal form is 0.25. Now to convert it to a percentage, you just multiply that by 100. So 25% of students in Alessandro's class live in Oakdale.
Answer:
the total area is 15.6 square units
Step-by-step explanation:
hello,
you can find the total area dividing the shape into two known shapes
total area= area of the trapezoid +area of the semicircle
then
step one
find the area of the isosceles trapezoid using
where
a is the smaller base
b is the bigger base
h is theheight
A is the area
let
a=2
b=5
h=4
put the values into the equation
Step two
find the area of the semicircle
the area of a circle is given by
but, we need the area of half circle, we need divide this by 2
now the diameter of the semicircle is 2, put this value into the equation
find the total area
total area= area of the trapezoid +area of the semicircle
so, the total area is 15.6 square units
Have a good day.
The first given equation is:
4x + 3y = 6
which can be rewritten as:
2(2x) + 3y = 6 .............> equation I
The second given equation is:
2x + 2y = 5
which can be rewritten as:
2x = 5 - 2y ........> equation II
Substitute with equation II in equation I to get the value of y as follows:
2(5-2y) + 3y = 6
10 - 4y + 3y = 6
-y = 6-10 = -4
y = 4
Substitute with the y in equation II to get x as follows:
2x = 5 - 2y
2x = 5 - 2(4)
2x = 5 - 8 = -3
x = -3/2
From the above calculations:
x = -3/2
y = 4
Answer:
18
Step-by-step explanation:
<span>The geometric average return is the the nth root of the product of the stock returns.
So we have nâš r1 * r2 * r3. Where n is the number of returns.
So we have 4âš(14.5 * 4.8 * 10.2 * 6 1)
This gives us 4âš ( 4330.512)
The fourth root of 4330.512 is 8.1121 percent.</span>
