Answer:
$3.91
Step-by-step explanation:
This is a fraction equal to
100 count ÷ 25.54 cost
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 25.54
100 count ÷ 25.54
25.54 cost ÷ 25.54
=
3.915427 count
1 cost
=
3.915427 count
cost
= 3.915427 count per cost
Step-by-step explanation:
The perimeter is the sum of all sides.
AB+AC+CB=75
(2x-9) + (2x+3) + (3x+4) = 75
Combine like terms:
(2x+2x+3x) + (-9+3+4) = 75
7x - 2 = 75
7x = 77
x=11
Replace 'x' with '11' in the above equations to find that:
AB = 2(11) - 9 = 22 - 9 = 13 m
AC = 2(11) + 3 = 22 + 3 = 25 m
CB = 3(11) + 4 = 33 + 4 = 37 m
13 + 25 + 37 = 75 m
The internal angles of a triangle sum to 180<span>°.
You already have two angles, since it is a right triangle one angle will always be 90</span>°, and the other is given as 56.666...<span>°
</span>
Subtract your two known angles from 180<span>° .</span>
Answer:
x = 22
Step-by-step explanation:
+ 2 = 6 ( subtract 2 from both sides )
= 4 ( square both sides to clear the radical )
x - 6 = 4² = 16 ( add 6 to both sides )
x = 22
