Calculs from the north you walk 1 mile and a temperature was 5 degrees from the west you walk 1 mile and the temperature change
MakcuM [25]

Answer: 6.4 degrees

Step-by-step explanation:

a= 5 degrees temperature difference to the north gives the opposite of the triangle,

b = 4 degrees temperature difference to the west gives the adjacent,

c = temperature difference of 1 mile to the south east gives the hypotenuse.

Therefore,

Using Pythagoras equation,

c² = b² + a²

c = sqrt( 5² + 4²)

c = sqrt(41) = 6.4 degrees

Therefore, there will be 6.4 degrees temperature difference 1 mile to the south east

Jose wants to build a rectangular kennel for his dog. His dad will let him use a spot in the corner of the yard that is 12 feet
Varvara68 [4.7K]
The answer is 42 ft 4 in

The perimeter of a rectangle with length l and width w is:
P = 2l + 2w

l = 12 ft 3 in
w = 8 ft 11 in

1 ft = 12 in
l = 12 * 12 in + 3 in = 144 in + 3 in = 147 in
w = 8 * 12 in + 11 in = 96 in + 11 in = 107 in

P = 2 * 147 + 2 * 107 = 294 + 214 = 508 in
P = 508 in = 504 in + 4 in = 42 * 12 in + 4 in = 42 ft 4 in

Jordan bikes at a speed of 8 2/3 mph. How many miles will he bike in 3 hours and 6 minutes?
Daniel [21]

Jordan will cover 26\frac{13}{15}\ miles in 3 hours and 6 minutes.

Step-by-step explanation:

Given,

Speed of Jordan = 8\frac{2}{3}=\frac{26}{3}\ mph

Time = 3 hours and 6 minutes.

Converting minutes into hour.

6 minutes = \frac{6}{60}\ hour = \frac{1}{10}\ hour

Therefore;

Time = 3+\frac{1}{10} = \frac{30+1}{10} = \frac{31}{10}\ hours

Distance = Speed * Time

Distance = \frac{26}{3}*\frac{31}{10}

Distance = \frac{806}{30}=\frac{403}{15}

Distance = 26\frac{13}{15}\ miles

Jordan will cover 26\frac{13}{15}\ miles in 3 hours and 6 minutes.
