2 answers:

The exclamation points mean you're looking for factorials.
5!3!/6! = ((5*4*3*2*1)(3*2*1))/(6*5*4*3*2*1)
(120*6)/720
720/720 = 1

5! = 5 * 4 * 3 * 2 * 1 = 120
3! = 3 * 2 * 1 = 6
6! = 6 * 5 * 4 * 3 * 2 * 1 = 720

120 * 6 / 720

= 1

PRE ALGEBRA / PLEASE HELP!!||| How many kilometers is it from the main gate to the Manatee Springs? (Hint: to convert from yards

mars1129 [50]

Answer:

6.04 km (per angle marks)
5.36 km (per side hash marks)

Step-by-step explanation:

Going by the angle indicators, the ratios of corresponding sides of the similar triangles are ...

x/2000 = 4200/3500

x = 2000·6/5 = 2400 . . . . yards

Then the distance of interest is ...

(2400 yd + 4200 yd)×(0.0009144 km/yd) = 6.6×.9144 km

= 6.03504 km ≈ 6.04 km

_____

Going by the red hash marks, the ratios of corresponding sides of the similar triangles are ...

x/2000 = 3500/4200

x = 2000·(5/6) = 5000/3 . . . . yards

Then the distance of interest is ...

(5000/3 + 4200) yd × 0.0009144 km/yd ≈ 5.36 km

_____

<em>Comment on the figure</em>

The usual geometry here is that the outside legs (opposite the vertical angles) are parallel, meaning that the angle indicators are the correct marks. It is possible, but unusual, for the red hash marks to be correct and the angle indicators to be mismarked. The red hash marks seem tentatively drawn, so seem like they're more likely to be the incorrect marks.

4. Tikili wants to invest $3500 at her local bank. She will receive an interest rate of 5% compounded

alexandr402 [8]

Answer:

$3863.35 = 3500(1 + \frac{0.05}{2} )^{(2 \times 2)}$

Step-by-step explanation:

The formula for this equation is

$a = p(1 + \frac{r}{n} )^{(n \times t)}$

a is the final result

p is the starting amount (deposited)

r is the interest rate

n is the number of times it's compounded

t is the time

because it says compound annually and it's after 2 years both t and n equal 2. I rounded a for you, but if you don't need it rounded here it is: 3863.345117

Please double check me I may be wrong, this is my second time doing these type of questions
