= 7(- 8)(- 9) + 11(2)(- 16) + 21(55)(- 1) - 21(- 8)(- 16) - 7(2)(- 1) - 11(55)(- 9) = <em>1768</em>

= 9.07(2.5)(2.35) + 6.02(3.5)(3.55) + 2.01(- 30.7)(- 1.1) - 2.01(2.5)(3.55) - 9.07(3.5)(- 1.1) - 6.02(- 30.7)(2.35) = <em>647.3561</em>
A² + b² = c² a and b are the legs and c is the hypotenuse.
7² + 24² = c²
49 + 576 = c²
625 = c²
√625 = √c²
25 = c
hope that helps, God bless!
We first find out the amount in dollars of interest accrued after 2 years time.
Interest = Prt
where P is the principal, r is the rate and t is time
8% written in decimal fraction → 8/100 → 0.08
Interest = 17000 × 8% × 2
Interest = 1700 × 0.08 × 2
Interest = 2,720 dollars
We add the principal and the interest to get full amount paid, so:
17000 + 2,720 = 19,720
I hope that you good day
Answer:
If the question states that they are not being replaced, then the answer is 1/8
If the question states that they are being replaced, then the answer is 1/9
Step-by-step explanation:
3/9 x 2/8 = 1/8
3/9 x 2/9 = 1/9
