The dimensions and volume of the largest box formed by the 18 in. by 35 in. cardboard are;
- Width ≈ 8.89 in., length ≈ 24.89 in., height ≈ 4.55 in.
- Maximum volume of the box is approximately 1048.6 in.³
<h3>How can the dimensions and volume of the box be calculated?</h3>
The given dimensions of the cardboard are;
Width = 18 inches
Length = 35 inches
Let <em>x </em>represent the side lengths of the cut squares, we have;
Width of the box formed = 18 - 2•x
Length of the box = 35 - 2•x
Height of the box = x
Volume, <em>V</em>, of the box is therefore;
V = (18 - 2•x) × (35 - 2•x) × x = 4•x³ - 106•x² + 630•x
By differentiation, at the extreme locations, we have;

Which gives;

6•x² - 106•x + 315 = 0

Therefore;
x ≈ 4.55, or x ≈ -5.55
When x ≈ 4.55, we have;
V = 4•x³ - 106•x² + 630•x
Which gives;
V ≈ 1048.6
When x ≈ -5.55, we have;
V ≈ -7450.8
The dimensions of the box that gives the maximum volume are therefore;
- Width ≈ 18 - 2×4.55 in. = 8.89 in.
- Length of the box ≈ 35 - 2×4.55 in. = 24.89 in.
- The maximum volume of the box, <em>V </em><em> </em>≈ 1048.6 in.³

Answer:
1) <u><em>Formula for experimental probability:</em></u>
Experimental Probability = 
2) Any performance or a random experiment is called a trial.
There are 184 people
there are 8 people in each table.
184÷8= 23 tables
she need 23 tables
Answer:
Calgary is the coldest
Step-by-step explanation:
The simple way to determine this will be to change the value of temperatures given in Fahrenheit to Celsius
32 F = 0°C
Formula to apply will be (T-32)×5/9 -------------where T is temperatures in Fahrenheit
Bangor is -3F-------------------change to Celsius
(-3-32)×5/9 =-35 × 5/9 = -19.44°C
Fairbanks is -12 ------------------------change to Celsius
(-12-32)×5/9 = -44 × 5/9 = -24.44°C
Fargo is -8 F ---------------------Change to Celsius
(-8-32)×5/9= -40×5/9 = -22.22°C
Calgary is -15 F-------------------------Change to Celsius
(-15-32)×5/9 = -47×5/9 = -26.11°C--------------coldest
Answer:
A) Yes the 2 triangles are similar by SSS Similarity and SAS Similarity
Step-by-step explanation:
SSS:
ST/SU = SW/SV = WT/VU
60/70 = 48/56 = 30/35
6/7 = 6/7 = 6/7
SAS:
ST/SU = SW/SV = 6/7 (look at SSS proving)
Angle S = Angle S because they are reflexive or the same angles
