Answer:

7 miles are equivalent to 36,960 feet

Step-by-step explanation:

We can solve this using a rule of three, in which we know that 2 and one half or 2.5 miles are equivalent to 13,200 feet, then how many feet are equivalent to 7 miles. This is:

13,200 feet ------------------  2.5 miles

         X         ------------------  7 miles

Where X is the number of feets equivalent to 7 miles. Then, solving for X, we get:

X=\frac{13,200 * 7}{2.5}=36,960

Finally, 7 miles are equivalent to 36,960 feet

50 out of the 80 were adults if you have to round so it would be 5/8 then you just do 8×100 and then 5×180+70÷100 because you're want to do not do not do it

How many square feet of outdoor carpet will we need for this hole
Fed [463]

Answer:

40 ft²

Step-by-step explanation:

The shape of the outdoor carpet can be decomposed into 2 triangles and 1 rectangle

✔️Area of triangle 1:

Area = ½*bh

b = 6 - 3 = 3 ft

h = 11 - 7 = 4 ft

Area of triangle 1 = ½*3*4 = 6 ft²

✔️Area of triangle 2:

Area = ½*by

b = 2 ft

h = 3 ft

Area of triangle 2 = ½*2*3 = 3 ft

✔️Area of rectangle = L × W

L = 11 ft

W = 3 ft

Area of rectangle = 11 × 3 = 33 ft

✅area of outdoor carpet = 4 + 3 + 33 = 40 ft²

Anyone... Someone... please.... hElP mE. im getting sick of this online school stuff
Kobotan [32]

Answer:

30,40,50

Step-by-step explanation:

If it is a right triangle then the pythagorean theorum would work

a^2+b^2=c^2

30^2+40^2=50^2

900+1600=2500

2500=2500

this means that 30,40,50 is the right answer

*******extra********

also 30,40,50 is a pythagorean triplet

pythagorean triplets form right angles

this one came from the original triplet of 3,4,5---just multiply by 10

GaryK [48]

Answer:

Step-by-step explanation:

1¾ miles/(2⅓ minutes) = (7/4 miles)/(7/3 minutes) = ¾ mile/minute

21 minutes × ¾ mile/minute = 15.75 miles

60 minutes × ¾ mile/minute = 45 miles
