Answer:
let sum of money be x
amount=rupees5454
rate=8%
time=30 months
convert month into year
30/12=5/2 years
Step-by-step explanation:
interest=p*t*r/100
=x*5*8/100*2
=40x/200
=x/5
so to find principal use formula
amount=principal +interest
5454=x+x/5
5454=5x+x/5
5454*5=6x
27270/6=x
4545=x
therefore ,sum of money(principal)=rupees.4545
Hope this helps u!!
Answer:
14x + 23
Step-by-step explanation:
The lengths of three sides of a triangle are 5x + 9 feet, 2x + 14 feet, and 7x feet.
The perimeter of a triangle: the sum of all of its sides.
5x + 9 + 2x + 14 + 7x
14x + 23
It's the expression of the perimeter of the triangle. Once you will be asked to find x, you'll probably be given the exact perimeter of the triangle.
Answer:
B.) 73°
Step-by-step explanation:
To find m<A, first you must find it's supplementary angle. In order to do this, you must determine the missing interior angle. We'll call the missing angle x
A pentagon has 540°. Add up the known angles.
96°+118°+115°+104°+x = 540°
433°+x = 540°
x = 107°
Now that we know the value of x, we can find the m<A. Supplementary angles are two angles that add up to 180°, which is a flat line. We can see in the diagram that m<a + 107° is a flat line, meaning m<a + 107° = 180°
Solve accordingly.
m<a + 107° = 180°
m<a = 73°
A parallelogram does not need to have all its sides equal. It just needs two pairs of equal opposite sides. A rhombus on the other hand, has to have all its four sides equal. A rhombus is actually a special form a parallelogram. So, a rhombus is always a parallelogram but a parallelogram is not always a rhombus.
