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.

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

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:

Mean x¯¯¯ 2.2

Median x˜ 1

Range = 9

Q1 --> 0

Q2 --> 1

Q3 --> 3

Interquartile range: 3

Mean Absolute Deviation (MAD): 2.08

Standard deviation : 2.71

Step-by-step explanation:

1. Number of absent students:

0,1,1,0,3,2,5,1,9,0

Find the:

Mean

0, 0, 0, 1, 1, 1, 2, 3, 5, 9/10

= 22/10

= 2.2

Median

0, 0, 0, 1), 1, 1, (2, 3, 5, 9

= 1 + 1/2

= 2/2

= 1

Lower quartile

Upper quartile

Range

= 9 - 0

= 9

Interquartile range = 3

Mean absolute deviation = 2.08

Standard deviation = 2.71

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:

vertex

the point on the parabola where the graph changes from increasing to decreasing.

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: x=48

Step-by-step explanation:

first add 9 to both sides

then add 27 to 9 to get 36

multiply both sides by 3/4 the reciprocol of 4/3

and youll get x=36 x (4/3)

simply to a single fraction then

then divide 144 by 3  to get 48
