Answer: B
Step-by-step explanation:
(I tried)
The formula for the area of a circle is <u>A (area) = π (3.14) x R (radius) ^2 </u>(second power)
Since the word problem gave the diameter, you can divide that by 2 to give you 9, aka the radius. (Radius + Radius = Diameter, diameter divided by 2 gives you radius)
Looking back at the formula, R^2 (it always comes first), 9^2 (9x9) equals 81 and then multiplying pi (3.14) to get your answer of 254.34 in.
Answer:
XY is a tangent
Step-by-step explanation:
Given
Required
Is XY a tangent?
XY is a tangent if:
Because XY should make a right angle at point X with the circle
Where
So, we have:
This gives:
<em>Yes, XY is a tangent</em>
Total cost = $15,867 + $(15,867 x 0.0525) = $15,867.00 + $833.02 = $16,700.02
10% of the total cost = 0.1 x $16,700.02 = $1,670.00
Principal balance = $16,700.02 - $1,670.00 = $15,030.02
Answer:
The ratio of the amount of money he saves to the amount of money he can spend is <u>2:3</u>.
Step-by-step explanation:
Given:
Jacob receives $10 per week for his allowance.
His parents have asked him to put four dollars in his savings account and the rest of his allowance in spending money.
Now, to find the ratio of the amount of money he saves to the amount of money he can spend.
Jacob receives per week money = $10.
He saves money = $4.
He can spend money =
Now, to get the ratio of money he saves to the money he can spend:
<u><em>He saves money : he can spend money.</em></u>
<em>On simplifying it:</em>
Therefore, the ratio of the amount of money he saves to the amount of money he can spend is 2:3.
$350 times 3% = 10.5
10.5 times 10 years = 105
the answer is 105
