Answer:
8
Step-by-step explanation:
area of a triangle= b x h x 1/2 or b x h /2
the base is 4 and the height is 4
4x4/2
=16/2
=8
Answer:
21 kilometers
Step-by-step explanation:
Let the height be
. Then, the length of the base is
. The formula for the area is of the triangle is given by base*height/2. Therefore, the area of the triangle is equal to
, which is in turn equal to 441. Since
must be positive, then
, meaning that the height is
kilometers.
Answer:
04 is ten times as great as which decimal. 0.04 = 10 times decimal number . 0.04 = 10 * x. On dividing both sides by 10. x = . x = 0.004. Therefore, Decimal number 0.004

<span>We are not told how often the interest is compounded, so assuming it is <em /><u><em>compounded yearly</em></u>, you need to keep $9.99 in the account to pay the fee.
<u><em>Explanation: </em></u>
Compound interest follows the formula A=p(1+r)^t,
where:
A is the total amount in the account,
p is the amount of principal,
r is the interest rate as a decimal number,
and t is the number of years.
<u>For our problem: </u>
A = 9.99,
p is unknown,
r = 0.018% = 0.00018,
and t=1.
<u>This gives us: </u>
9.99=p(1+0.00018)^1;
9.99=p(1.00018).
<u>Divide both sides by 1.00018: </u>
9.99=p.</span>
1) 0.5m . 2 = 1 meter
2) 4.70$
3) (r^2) / 2 = 81/2 = 40.5m^2
