Answer: To determine which statement is true, first find the measure of the third interior angle. You can do that by subtracting the two known interior angle measures from 180, since interior angle measures of all triangles add to equal 180 degrees.

180 - 65 - 57 = 58

The measure of the third interior angle is 58°.

Now, the largest side of triangle is opposite its largest interior angle; that means the largest side of this triangle is the side opposite the angle that measures 65° - the side representing swim distance. This is true for the middle and smallest sides as well - they're opposite the middle and smallest interior angles. The following shows the sides from largest to smallest as they correspond to angle measures from largest to smallest.

65° = swim
58° = bike
57° = run

Now to finally determine which statement is true.
Statement A is false because run distance is the smallest distance of all three distances.
Statement B is false because, as we've said, run distance is the smallest distance.
Statement C is false because swim distance is greater than bike distance.

That means that the correct answer is D - the bike distance is greater than the run distance.

Expresa en forma algebraica. ⦁ El cuadrado de un número aumentado en 1. ⦁ Cinco veces un número menos 8. ⦁ El número siguiente a un múltiplo de 5. ⦁ Un número impar.

Answers

Answer:

1) N^2 + 1

2) 5*N - 9

3) n*5 + 1    (con n entero)

4) n*2 + 1    (con n entero)

Step-by-step explanation:

1)  El cuadrado de un número aumentado en 1.

Podemos definir a N como el número.

El cuadrado de N es:

N^2

Y a esto lo tenemos que aumentar en 1, entonces tenemos:

N^2 + 1

Esto es el cuadrado de un número aumentado en 1.

2)  Cinco veces un número menos 8.

Esto es:

5*N  (5 veces un número)

Y a esto le restamos 8, para obtener:

5*N - 8

3) El número siguiente a un múltiplo de 5

Un multiplo de 5 se escribe como:

n*5

Donde n es un número entero.

El numero siguiente es:

n*5 + 1

4) Un número impar.

Bien, sabemos que un número par es un multiplo de 2.

Entonces:

n*2 es un número par.

Entonces, n*2 + 1 tiene que ser un numero impar.

En este caso la expresión algebraica es:

n*2 + 1

The distance from London to Manchester is 199.9 what is this to the nearest 10 miles?

Emilio keeps 92% of his trading cards in a binder. What fraction of trading cards does he keep in his binder?

Answers

92/100 which simplifies to 24/25
"Percent" means "over 100." So 92% is:

(92)/(100)

This can be reduced by dividing both the numerator and denominator by 4 to get:

(23)/(25)

This is the fraction of trading cards he keeps in his binder.

Tara's player for cds the length of the cds are 45 minutes 52 minutes 38 minutes and 47 minutes if it takes her 2 minutes to change each cd how long will it take to play all four cds

Answers

To determine the amount of time she will need to play all the cd's, we add up the time in minutes.
                          45 minutes + 52 minutes + 38 minutes + 47 minutes
which is equal to 182 minutes. Then, Tara needs to shift from one cd to another for 3 times and this will take her a total of 6 minutes. Thus, the total number of minutes she will need in order to play all four cds is 188 minutes.
