• ## How to find the perimeter of this figure?

For some reason this seemingly easy problem confuses me. The only possible answer I could think of is C, but I'm not sure if I'm correct, please help!
• ## Is calculus really necessary for a business major?

Yeah, I really see how ∫(x)dx=F(b)-F(a) is gonna help me in marketing.

• ## This is probably a stupid question?

Is -2 smaller than -1??? I'm sorry but negative numbers confuses me sometimes.
• ## Is mathematics related to science?

Best answer: Yes, Mathematics is related to Science, just like Games & Recreation, Home & Garden, News and Events, Politics & Government, Pregnancy & Parenting or Society & Culture.

• ## HELP MATH EXAM TMR!?

A diagonal of a rectangle forms a 30 degrees angle with the 25cm base of the rectangle. What is the width of the rectangle?
• ## Concrete...cubic foot using pounds?

Seventeen thousand pounds of concrete are poured to form a concrete patio. The concrete weighs 153 pounds per cubic foot. Approximately how many cubic feet of concrete are poured to form the patio? (Round your answer to the nearest whole number.)  =ft3

• ## How much weight could a leather belt hold before it breaks?

Best answer: Depending on the leather quality, the strength of cowhide leather varies from around 8 to 25N per square millimetre of cross section.

Stiffer leathers as used for belts are in the stronger range, so call it 20N per mm^2 at a rough guess.
(Soft leathers such as used for gloves & jackets etc. are at the lower end of the strength range).

If the belt is 25mm wide and 4m thick, that's 100mm^2 section so very roughly 2000N or 200Kg breaking strain.

That is for a single piece. As a loop, so doubled (and if the buckle can take the strain), it should hold roughly double that.

The figures are also based on the belt being real leather and not a plastic fake or composite "bonded leather" which is again largely plastic.

• ## What is the fraction of 2 2/6 x 4 4/6?

What is the fraction of 2 2/6 x 4 4/6?

• ## HELP MATH EXAM TOMMOROW!?

The length of the altitude from the base of an isosceles triangle to its vertex angle is 12 cm the vertex angle has a measure of 72 find the length of one of the congruent sides
• ## ((-4/3)x^3-6x^2+16x+66)/(x+3). How do you divide this? The fraction is throwing me off. Should i multiply every term by 3 to remove it?

The partial product is (-4/3)x^3 - 4x^2.
The remainder is -2x^2 + 16x + 66.
The 2nd term of the quotient will be -2x.
The partial product is -2x^2 - 6x.
The remainder is 22x + 66.
The third term of the quotient will be 22.
The partial product is 22x + 66.
There is no remainder.

Final answer: the quotient is (-4/3)x^2 - 2x + 22.
