The Table Below Gives The Height And Shoe Sizes Of Six Randomly Selected Men If The Man Has A Height

Answers

Answer 1

y = 2.5x + 45.9

The Height is 72.3

How to find the calculation?

Height = y

Shoe size = x

y = 1 / 6 (67 + 70+ 73.5 + 75 + 78 + 66) ≈ 71.6

x = 1/6 (8.5 + 9.5 + 11 +12 + 13 + 8 ) = 10.3 ≈10.3

=(67 * 8.5 + 70 * 9.5 + 73.5 * 11 + 75 * 12 + 78 * 13 + 66 * 8/ (8.5)² + 9.5 ² + 11 ² + 12 ² + 13 ² + 8²) - 6 * 10.3²

= 4485 - 4424.88 / 660.5 - 636.54

= 60.12 / 23.96

≈2.5

= 71.6 - 45 * 10.3 = 45.85 ≈45.9

⇒ y = 25 x + 45.9

When r = 10.5

y = 25 * 10.5 + 45.9 =72.15.

Priya's family exchanged 250 dollars for 4,250 pesos. Priya bought a sweater for 510 pesos. How many dollars did the sweater cost? Pesos dollars 4,250 250 25 1 3 510

Answers

Answer:

$30

Step-by-step explanation:

since they exchanged them we can assume they are worth the same

250=4250

First find how many pesos is worth 1 dollar

4250/250= 17

Then divide the amount the sweater costs by how much 1 dollar would be

510/17= 30

The sweater would cost 30 dollars.

P varies inversely with x. If P = 12 when x = 4, find the value of P when x = −48.

Answers

Answer:

P = - 1

Step-by-step explanation:

Given P varies inversely with x the the equation relating them is

P = [tex]\frac{k}{x}[/tex] ← k is the constant of variation

To find k use the condition P = 12 when x = 4

12 = [tex]\frac{k}{4}[/tex] ( multiply both sides by 4 )

48 = k

P = [tex]\frac{48}{x}[/tex] ← equation of variation

When x = - 48, then

P = [tex]\frac{48}{-48}[/tex] = - 1

Seis albañiles hicieron una barda de 180 m2 durante 12 días. ¿Cuántos días necesitaran 5 albañiles para levantar una barda de 100 m2 ?

Answers

Answer:

8 dias

Step-by-step explanation:

Primero tenemos que averiguar cuantos m2 pueden levantar los seis albañiles en 1 dia. Esto lo calculamos dividiendo los 180m2 por los 12 dias que les llevo hacerlo.

180 / 12 = 15 m2 por dia

Ahora tenemos que dividir este numero por los 6 albañiles para calcular cuantos m2 hace 1 albañil por dia

15 / 6 = 2.5

Ahora tenemos que multiplicar este m2 por los 5 albañiles que pide la pregunta

5 * 2.5 = 12.5 m2 por dia

Finalmente, necesitamos dividir los 100 m2 por los 12.5 m2 que pueden hacer los 5 albañiles por dia.

100 / 12.5 = 8 dias

16. if 1/3=2/3 then ?=3/3. to find 1/3 divide both by 2, 2/3 divided by 2=1/3, 1/3 divided by 2 = 1/6. then to find 3/3 multiply both by 3, 1/3x3=3/3, 1/6x3=1/2

What are the x-intercepts of the graph of y = (5x + 7) (2x - 1)(x – 4)?

Answers

Answer:

12x × 1x × 3x = 36x

)))))))))))))))))))

All the x - intercepts of the graph of y = (5x + 7) (2x - 1) (x - 4) will be;

⇒ - 7/5 , 1/2 , 4

What is mathematical expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The graph of the function,

⇒ y = (5x + 7) (2x - 1) (x - 4)

Now,

Find x - intercept of the equation as;

Substitute y = 0, we get;

⇒ y = (5x + 7) (2x - 1) (x - 4)

⇒ (5x + 7) (2x - 1) (x - 4) = 0

This gives three conditions as;

⇒ 5x + 7 = 0

And, 2x - 1 = 0

And, x - 4 = 0

After solve we get;

⇒ 5x + 7 = 0

⇒ x = -7/5

And, 2x - 1 = 0

⇒ x = 1/2

And, x - 4 = 0

⇒ x = 4

Hence, All the x - intercept = -7/5 , 1/2 , 4.

Therefore, All the x - intercepts of the graph of y = (5x + 7) (2x - 1) (x - 4) will be;

⇒ - 7/5 , 1/2 , 4

First, we must solve for the parenthesis so...

-2x-8=4x+16

Then we must simplify this even more so lets add the 8 to 16

-2x=4x+24

Then we must subtract 4x from -2x

-6x=24

we must now divide 24 by -6 so we can isolate the x
