Answer:
The principal amont was $35,000
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:

In which E are the earnings, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
In this problem, we have that:

We want to find P. So





The principal amont was $35,000
The new size of cube's side is 6. V new cube = 6*6*6 = 216
Answer:
80k
Step-by-step explanation:
let the previous weight be x
88=x + 10%of x
88=x+(10/100)of x
8800=110x
8800/110=x
x=80k
Answer:
15 unit
Step-by-step explanation:
Applying
/RT/ = √[(y₂-y₁)²+(x₂-x₁)²]............. Equation 1
Where /RT/ = distance between point R and Point T
From the question,
Given: y₁ = -9, x₁ = 8, y₂ = -9, x₂ = -7
Substitute these values into equation 1
/RT/ = √[(-9-(-9))²+(-7-8)²]
/RT/ = √[(0)²+(-15)²]
/RT/ = √225
/RT/ = 15 unit
Hence the distance between point R and point T is 15 unit
Y=5x-4. 5x4=20,5x-4=20
y=-20
