Answer:

  • 533 1/3 m, 900 m, 4 1/8 laps

Step-by-step explanation:

  • <em>A telesecundaria school has a race track that is 3/5 of a kilometer long. Three students ran the following distances: Juanita 1 1/3 laps, Esperanza 2 1/4 laps and Evelyn: 1650 m, how many meters did Juanita and Esperanza run? And how many laps did Evelyn turn?</em>

---------------------------

<em>1 lap = 400 m</em>

<u>Juanita ran:</u>

  • 1 1/3 laps = 4/3 laps = 4/3*400 m = 1600/3 m=  533 1/3 m

<u>Esperanza ran:</u>

  • 2 1/4 laps = 9/4 laps = 9/4*400 m = 900 m

<u>Evelyn ran:</u>

  • 1650 m = 1650 *1/400 = 4 50/400 laps = 4 1/8 laps

\sqrt[3]{\frac{-27x^9}{64y^{12}}}

we take cube root separately

\sqrt[3]{-27} =\sqrt[3]{-3*-3*-3} =-3

We know cuberoot (x^3) is x

\sqrt[3]{x^9}=\sqrt[3]{x^3*x^3*x^3}=x*x*x= x^3

\sqrt[3]{64} =\sqrt[3]{4*4*4}= 4

\sqrt[3]{y^{12}} =\sqrt[3]{y^3*y^3*y^3*y^3}= y*y*y*y= y^4

\sqrt[3]{\frac{-27x^9}{64y^{12}}}=\frac{-3x^3}{4y^4}

A food production company is choosing between two suppliers of grain. Supplier A sells grain for $5.25 per bushel plus a deliver
Arisa [49]
Supplier A: 5.25 per bushel and deliver fee of 3 per bushel
Supplier B: 6.50 per busher and flat delivery fee of $1500 each week

500 bushels of grain each week.

Supplier A: 5.25x + 3x = 5.25(500) + 3(500) =  2,625 + 1,500 = 4,125
Supplier B: 6.50x + 1500 = 6.50(500) + 1500 = 3,250 + 1,500 = 4,750

Supplier B would cost more if the company buys 500 bushels of grain per week.

What is the next term of the arithmetic sequence? -2,-4,-6
hichkok12 [17]

Answer:

- 8

Step-by-step explanation:

The common difference d between consecutive terms is

d = a_{2} - a_{1}, that is

d = - 4 - (- 2) = - 4 + 2 = - 2

To obtain the next term subtract - 2 from - 6

next term = - 6 - 2 = - 8

Verify a ÷ b ≠ b ÷ a , if a = −3/4 and b = 4/5
Shalnov [3]

Given:

a=-\dfrac{3}{4}

b=\dfrac{4}{5}

To verify:

a\div b\neq b\div a

Solution:

We have,

a=-\dfrac{3}{4}

b=\dfrac{4}{5}

Now,

a\div b=\dfrac{a}{b}

a\div b=\dfrac{-\dfrac{3}{4}}{\dfrac{4}{5}}

a\div b=-\dfrac{3}{4}\times \dfrac{5}{4}

a\div b=-\dfrac{15}{16}               ...(i)

And,

b\div a=\dfrac{b}{a}

b\div a=\dfrac{\dfrac{4}{5}}{-\dfrac{3}{4}}

b\div a=\dfrac{4}{5}\times (-\dfrac{4}{3})

b\div a=-\dfrac{16}{15}               ...(ii)

From (i) and (ii), it is clear that

a\div b\neq b\div a

Hence verified.
