1 1/4×-1 1/3 is equals to?​

Mathematics
1 answer:
slavikrds [6]3 years ago
3 0

Answer: -\frac{5}{12}

Steps:

1\frac{1}{4}\times \left(-1\right)\frac{1}{3}

Convert mixed numbers to improper fractions: 1\frac{1}{4}=\frac{5}{4}

=\frac{5}{4}\times \left(-1\right)\frac{1}{3}

\mathrm{Apply\:the\:rule}:\quad \:a\left(-b\right)=-ab

\frac{5}{4}\left(-1\right)=-\frac{5}{4}\times \:1

=-\frac{5}{4}\times \:1\times \frac{1}{3}

\mathrm{Apply\:rule}\:a\times 1=a

=-\frac{5}{4}\times \frac{1}{3}

\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}

\frac{5}{4}\times \frac{1}{3}=\frac{5\times \:1}{4\times \:3}

=-\frac{5\times \:1}{4\times \:3}

\mathrm{Multiply\:the\:numbers:}\:5\times \:1=5

=-\frac{5}{4\times \:3}

\mathrm{Multiply\:the\:numbers:}\:4\times \:3=12

=-\frac{5}{12}

Hope This Helps!

A cylinder has a radius of 5 feet and a height of 8 feet. Which of the following can be used to calculate the volume of a cone t
Lilit [14]
The answer is 1 over 3(3.14)(5²)(8) 

The volume of the cylinder (V1) is:
V1 = π · r² · h                (r - radius, h - height)

The volume of the cone (V2) is:
V2 = 1/3 π · r² · h         (r - radius, h - height)

It is given:
r = 5 feet
h = 8 feet
π = 3.14

Therefore, the volume of the cone is:
V2 = 1/3 · 3.14 · 5² · 8   which is the same as 1 over 3(3.14)(5²)(8).

You have 100 yards of fencing available to create an enclosure for farm animals. As the
Sunny_sXe [5.5K]
1. area of a pentagon when 1 side is x is \frac{x^2}{4}\sqrt{5(5+2\sqrt{5})}
so if perimiter is 100 then one side is 100/5 or 20
area will be \frac{20^2}{4}\sqrt{5(5+2\sqrt{5})}≈<span>688.2 square yards

2. area of a hexagon when 1 side is length x is \frac{3x^2\sqrt{3}}{2}
so if permiter is 100 then length of one side is 100/6 or about 16.666666666666
the area will be \frac{3(16.6666666)^2\sqrt{3}}{2}≈721.7 square yards

3. area of a regular octagon with side lenghts x is 2(1+\sqrt{2})x^2
so if 8 sides then side length of each is 100/8 or 12.5
area will be 2(1+\sqrt{2})12.5^2≈754.4 square yards


octagon wil have most space
you can tell because the more sides it has, the more it gets to a circle and the more area it encloses with a given perimiter
