Answer:
£5083
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 2.1%/100 = 0.021 per year,
then, solving our equation
I = 4600 × 0.021 × 5 = 483
I = £ 483.00
The simple interest accumulated
on a principal of £ 4,600.00
at a rate of 2.1% per year
for 5 years is £ 483.00.
Answer:
Step-by-step explanation:
take angle A as reference angle
using cos rule
cos A=adjacent/hypotenuse
cos A=12/13
cos A=0.92
A=cos 23
A=23 degree
for ratio,
cos A=12/13
I saw the image. It formed 2 right triangles. 1 small and 1 big.
small triangle has a long leg of 4 feet and hypotenuse of 6 feet.
big triangle has a long leg of (x) and hypotenuse of 6 + 12 ft.
proportion:
4/6 = x / 18
4 * 18 = 6x
72 = 6x
72/6 = x
12 = x
The distance from the base of the stairs to the tallest column is 12 feet.
Drop a perpendicular from an obtuse vertex.
That makes a 30 - 60º right triangle, with
hypotenuse 6 and short leg 3. So the long leg,
which is the height of the rhombus, is 3√3 .
Since a rhombus is a parallelogram, its area
is base x height = 6 x 3√3 = 18√3 .
