a park is in the shape of a rectangle 8 miles long and 6 miles wide. how much shorter is your walk if you walk diagonally across
lesya [120]
You need to use this particular formula
a^2 + b^2 = c^2
this allows you to solve for the sides of a triangle which is what the diagonal would look like if u were to draw it. a equals the width of the park and b equals the height of the park.
6^2 + 8^2 = c^2
next you need to multiply 6 by the power of 2
36 + 8^2 = c^2
then the same for the 8
36 + 64 = c^2
then add the numbers together.
100 = c^2
after you add you get the square root of 100 which is 10. a square root is 2 numbers that multiply together to equal a particular number. square root is what you do to cancel out a power of 2
so if you walk diagonally you go 10 miles instead of 14 miles leaving a difference of a whole 4 miles.

hope I helped

7th and 8th graders at Marshall Middle are going on a field trip. The 7th graders use 10 small buses and 12 large buses for 504
Hunter-Best [27]

Answer:

by dividing 325 by 48.

The answer comes out to 6.77

But since the number of buses must be a whole number, we will need 7 buses to carry the 325 students and teachers on a field trip.

so the answer is 7 buses

14 Metric System Conversion. Convert 26.2 miles into kilometers and round to the nearest tenth. (Hint: 1 mile= 1.609 km)
Mekhanik [1.2K]

Answer:

42.1558 km

Step-by-step explanation:

We know that 1 mile = 1,609 km

Then use this data as a conversion factor.

If we want to transform miles to kilometers then our conversion factor should be:

\frac{1,609\ km}{1\ miles}

Now we must multiply the number of miles by this factori and thus we obtain the equivalent in kilometers

26.2*\frac{1,609\ km}{1\ miles} = 42.1558 km
