1.32:3 1/7 =(1.4y): 5/6

Mathematics
1 answer:
alina1380 [7]3 years ago
6 0

After solving 1.32:3 \frac{1}{7}=(1.4y):\frac{5}{6}  we get y=0.24

Step-by-step explanation:

We need to solve the ratio: 1.32:3 \frac{1}{7}=(1.4y):\frac{5}{6} and find value of y

Solving:

1.32:3 \frac{1}{7}=(1.4y):\frac{5}{6}

Converting fractions into decimals

1.32:3.14=(1.4y):0.83

Ratio can be written as:

\frac{1.32}{3.14}=\frac{1.4y}{0.83}

Now cross multiply

1.32*0.83=1.4y*3.14

1.09=4.39y

y=\frac{1.09}{4.39}

y=0.24

So, after solving 1.32:3 \frac{1}{7}=(1.4y):\frac{5}{6}  we get y=0.24

There is 1000cm3 of aluminum available to cast a trophy that will be in the shape of a right square pyramid. Is this enough alum
stealth61 [152]

The 1000 cubic centimeters of aluminium is enough for aluminium a trophy  that will be in the shape of a right square pyramid and has a base edge of 10 cm and a slant height of 13 cm.

Step-by-step explanation:

The given is,

                    Volume of aluminium available is 1000 cubic centimeters

                    Shape of trophy is right square pyramid

                    Trophy has a base edge of 10 cm and slant height of 13 cm

Step:1

                     Formula for volume of right square pyramid,

                                               Volume, V = a^{2}\frac{h}{3}.....................................(1)

                     Where, a - Base edge value

                                  h - Height of pyramid

                      From given,

                                        a = 10 cm

                                        h = 13 cm

                      Equation (1) becomes,

                                           = 10^{2}(\frac{13}{3}  )

                                           = (100)(4.333)

                                           = 433.33 cm^{3}

             Volume of trophy = 433.33 cubic centimeters

             Compare with the volume of available aluminium and volume of right square pyramid,                          

            Volume of available aluminium > Volume of right square pyramid

                                               1000 cm^{3} > 433.33 cm^{3}

            So, the given volume of aluminium is enough to make right square pyramid shaped trophy.

Result:

          The 1000 cubic centimeters of aluminium is enough for aluminium a trophy  that will be in the shape of a right square pyramid and has a base edge of 10 cm and a slant height of 13 cm.

A box has a volume given by the trinomial x^3 5x^2 -24x What are the possible dimensions of the box?
vladimir2022 [97]
Volume is legnth times width times height so 3 dimentions
thee teacher probabl y wants you to factor the trinomial into 3 factors so
x^3+5x^2-24x
first factor out x
x(x^2+5x-24)
then factor
find what 2 numbers multiply to get -24 and add to get 5
the numbers are -3 and 8
x^2+5x-24 factors to
(x-3)(x+8)
the factored form is
(x)(x-3)(x+8)=volume
no dimention can be ≤0 so therefor
x≤0

x-3≤0
add 3
x≤3

x+8≤0
subtract 8
x≤-8

so the values for x is x<3


so if you had the volume, let's say 42 then
x^3+5x^2-24x=42
subtract 42 from both sides
x^3+5x^2-24x-42=0
factor and set each to zero to find the dimentions
