Calculate the annual return percentage

Mathematics
1 answer:
xenn [34]3 years ago
5 0
The annual return percentages will be evaluated using the formula:
A=P(1+r/100)^n
where:
A=amount
P=principle
r=rate
n=time

a] A=$500, P=$400, n=1 years
500=400(1+r)^1
solving for r we shall obtain:
1.25=1+r
hence
r=1.25-1
r==0.25
annual rate of investment is 25%

b] A=2500+100=$2600, P=$ 2000, n=1 year
hence
2600=2000(1+r)^1
2600/2000=1+r
1.3=1+r
r=1.3-1
r=0.3 
annual rate of investment is 30%

Norma bought 1 3/4 yards of cotton fabric and 3 3/8 yards of fleece fabric.
aalyn [17]
1 3/4 + 3 3/8 
get a common denominator by multiplying 1 3/4 by 2 to get a denominator of 8
1 3/4 becomes 1 6/8
1 6/8 + 3 3/8 = 5 1/8 yards
so the answer is 
C. 5 1 / 8 Yards

Hello! How do I find the surface area of this prism? Thanks!
Studentka2010 [4]
Answer: Choice C) 124 square cm

------------------------------------------------------------------

Explanation:

Let's calculate the area of the trapezoid shown
b1 and b2 are the parallel bases; h is the height of the 2D trapezoid
b1 = 2
b2 = 5
h = 1.5

A = h*(b1+b2)/2
A = 1.5*(2+5)/2
A = 1.5*7/2
A = 10.5/2
A = 5.25
The area of one 2D trapezoid is 5.25 sq cm
There are two of these trapezoids that form the base faces of the trapezoidal prism. So the total base area is 2*5.25 = 10.5 sq cm
Keep this value (10.5) in mind. We'll use it later.

------------

Now onto the lateral surface area (LSA)
It turns out that the formula for the LSA is
LSA = p*d
where 
p = perimeter of the trapezoid shown
d = depth or height of the 3D trapezoid (I'm not using h as it was used earlier)
This formula works for any polygonal base. It doesn't have to be a trapezoid.

In this case the perimeter is,
p = 1.7+2+2.65+5
p = 11.35

So
LSA = p*d
LSA = 11.35*10
LSA = 113.5

Add this LSA to the base area found earlier
10.5+113.5 = 124

The total surface area is 124 square cm

How can you use the point-slope form of a line when only given two points?
pshichka [43]

Answer:

See below

Step-by-step explanation:

<u>Point -slope form is:</u>

  • y - y1 = m(x - x1)

By having one set of coordinates and knowing the value of the slope (m in the equation) you can use the form.

<u>How to find the slope?</u>

Here you need 2 points: Point 1 with coordinates x1, y1 and point 2 with the coordinates x2, y2

<u>Use the formula:</u>

  • m = (y2-y1)/(x2-x1)

<u>Example:</u>

  • m = -5, and one of the points has coordinates (9, 2) then point-slope form is:
  • y - 2 = -5(x - 9)

neonofarm [45]

Answer:

n<1.3

Step-by-step explanation:

-2.5n+8.7>5.45

add -8.7 on both sides

-2.5n>-3.25

divide both sides by -2.5

n<1.3   (after division inequality sign changes)

answer of Q2 is -4 2/3

answer of Q3 is -2/9

answer of Q4 is -23/3

answer of Q5 is 2^2. 3^2.5
