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

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:

B.

Step-by-step explanation:

cuz you take 21 divide by 7 equals 3. 33 divided by 3 equals 11

Step-by-step explanation:

Answer:

$0.22

Step-by-step explanation:

Ellen has a coupon of 1.55 off a loaf of bread

The regular price of the bread is 4.63, the loaf is cut into 14 slices

Therefore if she uses her coupon the price per slice can be calculated as follows

= 4.63-1.55

= 3.08

3.08/14

= 0.22

Hence the price is $0.22

Answer:

the following is not a function

Step-by-step explanation:

the following is not a function because in order for it to be a function none of the x values can repeat and the x values repeat therefore it is not a function

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:

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
