You need to simplify by dividing:
135:100
(Divide both sides by 5 ,as it’s the HCF(Highest Common Factor) )
27:20 ( Keep as whole numbers)
For every R27 Jerry gets , John gets R20.

Best answer
A -1
B 1
C -3
D - 1/3
Answer:
Radius: 10 ft
Diameter: 20 ft
Area: 314.15 ft^2
Circumference: 62.83 ft
Step-by-step explanation:
The radius can be found using the diameter. The diameter is 20 feet which is the line that is given in the circle.
The radius(r) is equal to half the diameter(d):
r = d/2 --> r = 20/2 = 10 feet
The area(A) can be found using the radius(r) and pi or 3.14
A = pi(r^2) --> A = pi(10^2) = 314.15 feet^2
The circumference(C) is found by using the radius(r) and pi or 3.14
C = 2pi(r) --> C = 2pi(10) = 62.83 feet
Answer:
4^3
Step-by-step explanation:
When you are multiplying exponents with the same base (for this problem the base is 4) you add together the exponents. It is kinda hard to explain but that is just a rule you can use. So, 4^(5+(-2))=4^3
Answer: Her account would earn $17.5
Step-by-step explanation: The earning on a given amount with simple interest can be computed as follows;
Interest = PRT/100
Where P is the principal (initial amount), R is the rate of interest and T is the number of years. The formula now becomes,
Interest = (50 x 3.5 x 10)/100
Interest = 1750/100
Interest = 17.5
Therefore, in 10 years her account would have earned $17.5
