Ede4ka [16]

Answer: 60 ft

Step-by-step explanation:

Given

The perimeter of the garden is 220\ ft

The width of the garden is 50\ ft

Suppose the length of the garden is x

Perimeter is the sum of the lengths of the sides

\Rightarrow 220=2(x+50)\\\Rightarrow 110=x+50\\\Rightarrow x=60\ ft

So, the length of the garden is 60\ ft

A train leaves Roseville heading east at 6:00 am at 40 miles per hour. Another eastbound train leaves on a parallel track at 7:0
Molodets [167]

Answer:

At 11:00 am the both trains will be at same distance away from Roseville

Step-by-step explanation:

The first train was 40 miles away from Roseville at 7:00 am

After some time t the both trains will be at the same distance away from Roseville.

We will make equation for that situation

d- distance      v1= 40mph and v2= 50mph -  velocity

d =  v1*t + 40 = v2*t  => v2*t - v1*t = 40 => t (v2-v1) = 40 -> t = 40/ (v2-v1)

t = 40/(50-40) = 40/10= 4h      t = 4h

7:00 am * 4h = 11:00 am

Good luck!!!

On a number line, point D is at -3, and point E is at 6. The point F lies on . The ratio of to is 2 : 3. Where does point F lie
Kamila [148]

Answer:

F is at 3

Step-by-step explanation:

D                                                                       F                                   E

|________________|_________________|_________________|

-3                                0                                    3                                   6

With a ratio of 2:3, there are 3 sections on this number line ( -3 to 0, 0 to 3, and 3 to 6). Where the second section is is where the ratio would fit, because section 2 of 3 is the ratio 2:3.
