Answer:
359.01
Step-by-step explanation:
You take the original and then You look at the place value to the right. If it is 5 or more you round up if it is less you keep it the same. 359.006. 6 is more than five so you will round up. your answer then becomes 359.01
Answer:
$95
Step-by-step explanation:
I you need to see how much you would save after 7 weeks, and you save $10 a week, that would be 7*$10 and if you start with $25 you add it.
$25 + 7*($10) =
$25 + $70 = $95
After 7 weeks you would have saved $95.
If you need to know your savings each week, start with $25, and add $10 to it each week.
$25
Week 1 - $25 + 10 = $35
Week 2 - $35 + 10 = $45
Week 3 - $45 + 10 = $55
Week 4 - $55 + 10 = $65
Week 5 - $65 + 10 = $75
Week 6 - $75 + 10 = $85
Week 7 - $85 + 10 = $95
i. Line BD = 6√2 cm
ii. Perimeter = 3 (π + 4) cm
iii. Area = 18 ( π - 2) cm
<h3>How to determine the parameters</h3>
Let the length of BD = x
Since B is the midpoint of the arc AC, then ∠BOC = 15°
In ΔBDB
Let's use the trigonometric ration, tan
CD = x
Then, using the Pythagorean theorem
Thus, line BD is cm
ii. Perimeter = BC + BD + CD
= 2πr/8 + x + r - x
= π(12)/4 + r
= 3π + 12
= 3 ( π + 4) cm
iii. Area of shaded area = Area of BOC + Area of BOD
⇒ πr^2/8 × 1/2x^2
= π144/8 × 1/2(72)
= 18π - 36
= 18 ( π - 2) cm²

Answer:
x = (ab +a +b +c)/(a +b)
Step-by-step explanation:
Eliminate parentheses, subtract left terms not containing x, divide by the coefficient of x.
