Answer:
2.20752 x 
Step-by-step explanation:
The first thing you have to do is to look for the number of seconds in one year. You have to multiply 365 days by 86,400 seconds.
- 365 days refer to the total number of days per year
- 86,400 seconds refer to the number of seconds per day
Let's solve.
- 365 x 86,400 = 31,536,000 or 3.1536 x
<em>Therefore, one year has 3.1536 x </em><em> seconds.</em>
Next, you have to know the number of seconds in 10 billion years.
- (3.1536 x ) x (1.0 x
) = 3.1536 x 
The last step is to multiply the number of seconds in 10 billion years to 7 million tons of mass per second.
- (3.1536 x ) x 7,000,000 = 2.20752 x
Answer:
Cash price
Step-by-step explanation:
The computation is shown below:
The Interest rate per month (r) = (9% ÷ 12) = 0.75%
Now Present value of the monthly payment is
= PMT × {[(1 + rate of interest)^number of years - 1] ÷ rate of interest}
= 1,499 × {[(1 + 0.75%)^12 - 1] ÷ 0.75%}
= 18,748.89
And the cash price is 15,999
So, the cash price would be lower
Answer:
x = -3, y = -7
Step-by-step explanation:
Eliminate the equal sides of each equation and combine.
Solve 2x - 1 = 3x + 2 for x.
-x - 1 = 2
-x = 3
x = -3
Evaluate y when x = -3
y = 3 (-3) + 2
y = -7
(-3, -7)

Answer:
Dimensions are 12 , 5
Step-by-step explanation:
Area of rectangular mural = length * width
length * width = 60 square feet
(x + 10)(x + 3) = 60
Use FOIL method
x*x + x*3 + 10*x + 10*3 = 60
x² + <u>3x + 10x</u> + 30 = 60 {Combine like terms}
x² +<u> 13x</u> + 30 - 60 = 0
x² + 13x - 30 = 0
Sum = 13
Product = -30
Factors = 15 , -2 (15+ (-2) = 13 ; 15*(-2) = -30)
x² + 15x - 2x - 30 =0 {Rewrite middle terms}
x(x + 15) - 2(x + 15) = 0
(x + 15)(x - 2) =0
x - 2 = 0 {Ignore (x +15) as dimensions wont have a negative value}
x = 2
x + 10 = 2 + 10 = 12
x + 3 = 2 + 3 = 5
Dimensions are 12 , 5
