Answer:

The average service rate ($73) is far greater than the least service rate ($11), and far less than the highest service rate ($103).

Step-by-step explanation:

The service rate was given as $11, $84, $94 and $103.

The average service rate = \frac{sum of the service rate}{number of service rate}

                                          = \frac{11 + 84 + 94 + 103}{4}

                                          = \frac{292}{4}

                                          = 73

Their average service rate is $73.

But comparing the average service rate to their given service rates, the average service rate ($73) is far greater than the least service rate ($11), and far less than the highest service rate ($103).

valina [46]

Answer:

a) 0.64mm

b) 7/25

Step-by-step explanation:

Felipe trabaja en una construcción ayuda a cotizar materiales entre ellos cables para diversos propósitos.El arquitecto le pidió cotizar un cable de 16/25 mm de diámetro. en los catálogos disponibles en as tiendas las medidas aparecen expresadas en números decimales como se muestra en la imagen

¿Que debe hacer felipe para saber el diámetro del cable que pidió el arquitecto?

¿que medida en forma de fracción le corresponde al cable que mide 0.28? ¿como lo determinaste? es urgenteeee GRACIAS

a)Para que obtengamos la medida del material expresada como decimal, usaremos el método de división larga. compruebe el archivo adjunto para la solución a la división.

16/25 mm = 0,64 mm

b) La medida fraccionaria corresponde al cable que mide 0.28 se expresa como se muestra. Convertir 0,28 a fracción.

0.28 = 28/100 (Tenga en cuenta que dividimos por 100 porque hay dos valores decimales después del punto decimal)

Sobre la simplificación en su término más bajo

0.28 = 28/100 = 2*14/2*50

0.28 = 28/100 = 14/50

simplificando aún más

0.28 = 14/50 = 2*7/2*25

0.28 = 14/50 = 7/25

28/100 = 7/25

Por lo tanto, la medida fraccionaria que corresponde al cable que mide 0.28 es 7/25.

100 PTS:Please help me now plz plz
Alex Ar [27]

Answer:

x = 12

Step-by-step explanation:

We have a right triangle with hypotenuse 10 and the height 8.  Either the one on the left or the one on the right

We can find the base using the Pythagorean theorem

a^2 + b^2 = c^2

a^2 +8^2 = 10^2

a^2  +64 = 100

Subtract 64 from each side

a^2 = 100 -64

a^2 = 36

Take the square root of each side

a = 6

Now a is 1/2 of the total base of the big triangle.  It is identical since the triangles are equal

x = 2 * a

x = 2*6 = 12

Answer:

616 cm²

Step-by-step explanation:

To find the area of a circle you use the formula A = π · r²

So we know that the diameter is 28 cm, to find the radius we would divide this in half, because d = 2r, giving us 14. Now we can do 14² which is 196, and then times that by pi or in this case 22/7.

196 × (22/7) = 616

At a gas station, the price of a regular gas was $3.80 per gallon on monday. the price increased to $3.85 per gallon on tuesday.
notsponge [240]
Monday's gas, $3.80 rounded to the nearest tenth of a dollar would be $3.80 (its already there)
Tuesday' gas, $3.85 rounded to the nearest tenth of a dollar would be $3.90
Hope this helps!! and if you ever need anything else just ask! :)
