Step-by-step explanation:
A. 3x+4/2 = 9.5
3x + 4/2 = 9.5........criss cross
3x+4= 9.5×2
3x = 19-4
3x = 15
x=5 ..........divide both sides by 3
B. 7+ 2x/3= 5.......criss cross
7+2x = 5 × 3
7 + 2x = 15
2x = 15-7
2x = 8......divide both sides by 2
x = 4
Answer:
The area is 1,014 cm^2
Step-by-step explanation:
Here, we want to find the total surface area of a cube with side length of 13 cm
what we shall do here is to apply the formula to get the total surface area
Mathematically, that will be
A = 6L^2
so we have
Area = 6 * 13^2
Area = 1,014 square cm
Stance formula : d = sqrt (x2 - x1)^2 + (y2 - y1)^2
(3,5)(7,3)
d = sqrt (7 - 3)^2 + (3 - 5)^2
d = sqrt 4^2 + (-2^2)
d = sqrt 16 + 4
d = sqrt 20
d = 4.47....rounded = 4.5
Answer: 2,4???
Step-by-step explanation:
Answer:
n = 121
Step-by-step explanation:
Given,
Amount invested = $250,000
Quarterly payment (P) = $5500
Interest Rate (Quarterly) (r) = 8% /4 = 2%
Account balance = $ 0
Present value of Annuity formula ,
Present value =
1.02⁻ⁿ = 0.091
-n ln(1.02) = ln (0.091)
n = 121
Hence it will take 121 Quarters to account balance $0.
