Answer:

A. 38\ \text{grados}

Step-by-step explanation:

La temperatura en Moscú es de 13 grados bajo cero. Entonces, la temperatura es de -13 grados.

La temperatura en Buenos Aires es de 25 grados bajo cero. Entonces, la temperatura es de 25 grados.

La diferencia de temperatura entre las dos ciudades es

25-(-13)=38\ \text{grados}

La diferencia de temperatura entre las dos ciudades en un momento dado es  38\ \text{grados}.

Answer:

  1.67 m, 8.33 m

Step-by-step explanation:

If the ratio of lengths is 1 : 5, then the ratio of the shortest length to the total is ...

  1 : (1+5) = 1 : 6

The shortest length is (10 m)×(1/6) = 1.67 m. The longer length is 10 -1.67 = 8.33 m.

The lengths of the pieces are 8.33 m and 1.67 m.

Answer:

13 miles

Step-by-step explanation:

The shortest distance would be a straight line between the two points.  This would be a hypotenuse of a right triangle

We can use the Pythagorean theorem to determine the length

a^2+b^2=c^2

5^2 +12^2 = c^2

25+144= c^2

169 = c^2

Taking the square root of each side

sqrt(169) = sqrt(c^2)

13 = c
