Answer:
x = $2.56
Step-by-step explanation:
To solve this, you do the inverse of both operations, which is multiplication and subtraction. The first inverse would be addition, so 2.81 + 2.31 = 5.12. Then, the second inverse would be division, so 5.12 divided by 2 = 2.56. So therefore, x = $2.56 is the correct answer for the price in September 2006.
Answer:
See below.
Step-by-step explanation:
top left
9 × 9 = 81
9/81 = 1/9
top right
9 × 9 = 81
36/81 = 4/9
bottom left
6/72 = 1/12
bottom right
12/72 = 1/6
Answer:
13 is the answer (GE) i hope this helped
Let x be the number of hours that both will be the same.
27.5x = 23.25x + 17
27.5x - 23.25x = 17
4.25x = 17
x = 17 ÷ 4.25
x = 4
Ans: 4 hours
We have that
<span> points (−20, 21) and (0, 0)
Let
A----> </span>(−20, 21)
B-----> (0, 0)
using a graph tool
see the attached figure
step 1
find the distance AB
<span>applying the Pythagorean theorem
</span>
AB²=20²+21²--------> 841---------> AB=√841-------> 29
AB=29 units
cos <span>Θ=20/29-------> 0.6897
</span>
the angle <span>Θ belong to the second quadrant
therefore
the cos</span><span>Θ is negative
the answer is
the cos </span>
Θ is -0.6897
