Answer:

The speed of Train #940 is 68.[tex]\overline{571458}[/tex] mph

Step-by-step explanation:

The given parameters of the w=question are;

The time at which train #941 leaves the station = 7 a.m.

The speed with which train #941 travels, v = 48 mph

The time at which train #940 leaves the station = 3 hours after train #941

Therefore;

The time at which train #940 leaves the station = 3 hours + 7 a.m. = 10 a. m.

The direction of train #940 = The direction of train #941

The time at which train #940 catches train #941 = 5 p.m.

We have;

The time, 't', (after departure of train #941) it takes train #940 to catch train #941, is given as follows;

t = 5 p.m. - 7 a.m.

∴ t = 17:00 hours - 07:00 hours = 10 hours

The time (after departure of train #941) it takes train #940 to catch train #941, t = 10 hours

The distance from St. Mark's Train Station train #940 catches Train #941, 'd', is given as follows;

d =  The speed of travel of train #941 × t

∴ d = 48 mph × 10 h = 480 miles

The distance from St. Mark's Train Station train #940 catches Train #941, d = 480 miles

The time train

The time, t₂, it takes Train #940 to catch up with train #941 is given as follows;

t₂ = 5 p.m. - 10 a.m. = 17:00 hours - 10:00 hours = 7 hours

The speed of Train #940, v₂ = d/t₂

∴ v₂ = (480 miles)/(7 hours) = 68.[tex]\overline{571458}[/tex] mph

The speed of Train #940, v₂ = 68.[tex]\overline{571458}[/tex] mph

Answer:

7 ( b + 4 ) = 9

Step-by-step explanation:

Let the number be = b

It is given that the :

The number is added to 4.

And the value is equal to 9 when it is 7 times the sum of the number, b and 4.

Thus according to the question, the sentence can be translated in equation form as :

7 ( b + 4 ) = 9

Thus in other word, we can say that the addition of (b + 4) when it is multiplied for 7 times, we get the result as 9.

Answer: 1346cm

Step-by-step explanation:

From the question, we are informed that Reagan has a rectangular bedspread that measures 238 centimeters by 435 centimeters and that he wants to sew a fringe around the edge of the bedspread.

This simply means that we have to find the perimeter of the rectangular bedspread and this will be:

= 2(length + width)

= 2(435 + 238

= 2(673)

= 1346cm

The length of fridge needed by Reegan is 1346cm.

Step-by-step explanation:

here's your solution

=> it is given that.

=> height of cylinder = 15unit

=> radius of base = 9unit

=> volume of cylinder = π r^2h cubic unit

=> now, putting the value of height and radius

in above formula

=> volume = 22/7 *9*9*15

=> volume = 36177cubic unit

The value of volume of cylinder is,

⇒ volume = 36177 cubic unit

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

We have to given that.

In a cylinder;

Height of cylinder = 15unit

And, radius of base = 9unit

Since,  We know that;

volume of cylinder = π r²h cubic unit

Now, putting the value of height and radius as;

⇒ volume = 22/7 x 9x 9 x 15

⇒ volume = 36177 cubic unit

Thus, The value of volume of cylinder is,

⇒ volume = 36177 cubic unit

Answer:

7.2

Step-by-step explanation:

Use the distance formula:

d = [tex]\sqrt{(x2-x1)^2+(y2-y1)^2}[/tex]

Points of the diagonal: (-2, -2) and (2, 4)

d = [tex]\sqrt{(2-(-2))^2+(4-(-2))^2}[/tex]

d = [tex]\sqrt{(2+2)^2+(4+2)^2}[/tex]

d = [tex]\sqrt{(4)^2+(6)^2}[/tex]

d = [tex]\sqrt{16 + 36}[/tex]

d = [tex]\sqrt{52}[/tex]

d ≈ 7.2
