Luis is wrong because 8 to the third power is not 24, but is 512. He multiplied 8 by 3 instead of doing 8x8x8, so Luis made an incorrect claim.
Answer:
I was taught compound interest this way hopefully it helps.
100 + interest rate / 100 = multiplier
100 + 4.3 = 104.3. 104.3/100 = 1.043
Amount X multiplier to the power of time
82100 X 1.043^2 = 89312.4029
as it is a monetary unit round to 2dp
$89312.40
<span>3^3 ÷ 9 / 11 - 2^2
=27 </span>÷ 9 / 11 - 4
= 27 * 11/9 -4
= 297/9 - 4
=33-4
=29
Answer:
Area: ½ × base × height
Perimeter: sum of side lengths of the triangle
Number of vertices: 3
Number of edges: 3
Internal angle: 60° (for equilateral)
Sum of interior angles: 180°
Line of symmetry: 3
Step-by-step explanation:
The right answer is: <em>The binomial expression 2w + 6 represents the length of the fish tank.</em>
Dylan has a fish tank, so we assume that this tank is a cube. In this way, the volume of the tank is given by this expression:

Where:
h: height
w: width
l: length
We know the following things:
FIRST.<em> He knows its height, h, is one inch less than twice the width, w.</em>
This can be expressed as the following equation:

SECOND. <em>The length, l, of the fish tank is seven inches longer than the height.</em>
We can express this statement as follows:

By substituting
in
