Answer:
<em>It is C.</em>
<em>Any number(except maybe 0, do not play games with 0)) raised to 0 power is equal, so 5^2*1=25:</em>
Answer: 60°
Step-by-step explanation:
apply concept: the interior angle sum of triangle is 180°
x+x+x=180
3x=180
x=60
---------------
this is also an equilateral triangle which if you know it, you will know that each angles are all 60°
Answer:
$15.75
Step-by-step explanation:

y × 100 = 5 × 15
100y = 75
100y ÷ 100 = 75 ÷ 100
y = 0.75
$15 - $0.75
$14.25

y × 100 = 10 × 15
100y = 150
100y ÷ 100 = 150 ÷ 100
y = 1.5
$14.25 + $1.50
$15.75
Answer:
3.6miles
Step-by-step explanation:
Given:
distance of tent from the closest point on shore-line, d=3miles.
distance between shoreline point and coral reef, x=2miles
The shortest distance (say l) that the visitor runs towards the reef in order to swim a minimum distance which takes least time.

Now on reaching at the shore at this point the visitor will have to swim the least distance due east to reach coral reef.
Create a two variable system. 2h+3c=16 and 2h+10c=44 multiply one by -1 to cancel the 2h. ( I multiplied the second equation ) -7c=-28 --> c = 4
