Answer:
$167.2
Step-by-step explanation:
It has been given that the price of a new computer is $800.00 and refurbished computer with the same equipment has a price of $640.00.
Let us find the amount that we will save with a refurbished computer if we put the difference into the savings account for a year using simple interest formula.
, where A= Amount after t years, P=principal amount, r = interest rate (decimal form) and t=time.
Our principal amount will be the difference of prices of new computer and refurbished computer.
Upon substituting our given values in above formula we will get,
Therefore, we will save $167.2 with refurbished computer when we put the difference into the savings account for a year.

Answer:
Area of ΔXYZ = n(r * r) square units
Step-by-step explanation:
Sides of ΔABC are 30 units, 40 units and 60 units.
Corresponding sides of another triangle XYZ are r times as long as the sides of ΔABC.
Therefore, sides of ΔXYZ will be, 30r units, 40r units and 60r units.
Perimeter of the triangle XYZ = 30r + 40r + 60r
= 130r units
If the area of ΔABC = n square units
Then the ratio of the area of ΔXYZ and ΔABC = (Ratio of the sides of ΔXYZ and ΔABC)²
Area of ΔXYZ = nr² ≈ n(r * r)
Therefore, Option (3) will be the answer.
Answer:
10a = 30
Step-by-step explanation:
By using elimination:
4a + 2z = 10
-2(3a + z) = -2(-10)
4a + 2z = 10
6a - 2z = 20
2z and -2z cancel out
10a = 30
a = 3
They are asking for 10a, so 10 (3) = 30.
