A shipping company is creating their own shipping boxes. They have created a box with a volume of 800in^3, a helght of 8 inches

Kazeer [188]

Answer:

Length=10 Inches

Width=10 Inches

Step-by-step explanation:

Volume of the box $=800in^3$

Height=8 Inches

Base Perimeter =40 Inches

Volume of a box=lbh

SInce h=8 in, V=800.

Then:

8bl=800

bl=100

$l=\frac{100}{b}$

Base Perimeter=40 Inches

Perimeter of the Base= 2(l+b)

Therefore: 2(l+b)=40

Substituting $l=\frac{100}{b}$

$2(\frac{100}{b}+b)=40\\\frac{100+b^2}{b}=20\\$Cross Multiply\\100+b^2=20b\\b^2-20b+100=0\\$Solving the quadratic equation \\b^2-10b-10b+100=0\\b(b-10)-10(b-10)=0\\(b-10)(b-10)=0\\b-10=0 (Twice)\\b=10 \:Inch$

Recall:

$l=\frac{100}{b}=\frac{100}{10}\\l=10 Inch$

Therefore:

Length=10 Inches

Width=10 Inches

How do you find the dimensions of a cylinder (height, radius, diameter and area of the base) when you are given the volume of th

MariettaO [177]

Answer:

Step-by-step explanation:

the formula for a cylinder is πr^2 x H

if it equals 10 to find the others you just need to do algebra

$\pi r^{2} *h = 10$

$h =\frac{10}{\pi r^{2} }$

$r =\sqrt{\frac{\frac{10}{h} }{\pi } }$

to find diameter times it 2

What are the next 3 numbers in this sequence? 1,1,2,4,7,13,24,44

Bogdan [553]

81,149, 274.... adding three numbers from the last would help you

like if you take 7 = 4 + 2 +1

or 13 = 7 + 4 +2

similarly 44+24+13 = 81
81+44 +24 = 149
149 + 81 +44 = 274

hope you get it!
