Answer:

2x^2 + 7x + 3 is the area of the rectangular piece of wood.

Step-by-step explanation:

Here,

Length ( l ) = x + 3

Breadth ( b ) = 2x + 1

Formula : -

Ar ( rectangle ) = lb

lb

= ( x + 3 ) ( 2x + 1 )

= x ( 2x + 1 ) + 3 ( 2x + 1 )

= 2x^2 + x + 6x + 3

= 2x^2 + 7x + 3

Answer:

Their average daily income would be 45 dollars a day.

Step-by-step explanation:

To solve this, add the 15 tickets, 23, 20, and 32 tickets from Monday to Thursday. This should get you a total of 90 tickets. Since each ticket cost 2 dollars, multiply the 90 by 2. This should get you 180. TO find the average, you must divide the total(180) by the amount of days(4) that passed. This should get you 45.

Step-by-step explanation:

Lateral surface of the cylinder = 2πrh

Where,

r = 6 yd

h = 12 yd

π = 3.14

Plug in the values

Lateral Surface Area of the cylinder = 2*3.14*6*12

Area = 452.16 yd²

Answer:

x = 16

Step-by-step explanation:

Supplementary angles = 180

K + L = 180

137 + 3x - 5 = 180

132 + 3x = 180

3x = 180 - 132

3x = 48

x = 48/3

x = 16

Answer:

one shirt 25.00 one sweater 16.00

Step-by-step explanation:

$\text{one shirt: }\$25,\text{ one sweater: }\$16$

Let x be the cost of one shirt and y be the cost of one sweater; then

5x+5y6x+9y=205=294

The augmented matrix for this system of equations is

[5659205294]

Using Gaussian elimination, divide row one by 5 to get

[161941294]

Multiply row one by −6 and add the result to row two to get

[10134148]

Divide row two by 3 to get

[10114116]

After back substitution, y=16 and x=25.

The cost of one shirt is $25 and cost of sweater is $16.

Two or more expressions with an Equal sign is called as Equation.

Let x be the cost of one shirt and y be the cost of sweater.

5 shirts and 5 sweaters cost $205

5x+5y=205...(1)

6 shirts and 9 sweaters cost $294

6x+9y=294...(2)

Multiply equation (1) with 6 and equation (2) with 5.

30x+30y=1230..(3)

30x+45y=1470...(4)

Subtract 3 and 4

30y-45y=1230-1470

-15y =  -240

Divide both sides by 15

y=240/15

y=16

Now plug in y value in any of the equation

5x+16(5)=205

5x + 80 = 205

5x = 125

Divide both sides by 5

x=25

Hence, the cost of one shirt is $25 and cost of sweater is $16.

The Statement A which says that the mean of the two data sets are equal is the correct statement.

A boxplot is a standardized way of displaying the distribution of data based on a five number summary minimum, first quartile (Q1), median, third quartile (Q3), and maximum.

According to the given problem,

We can notice from the two box plots that the mean for both the box plots is less than 80 but greater than 75.

Hence, we can conclude that the mean of the two data sets are equal.

REASON: Since a rectangle is made of two right triangles then a rectangle inscribed in a circle must have its diagonal as the diameter of the circle.

Answer:

2.75

Step-by-step explanation:

So lets work this out:

First, we will need to convert 85 cm to meters. That would be 0.85 meters.

Now we can take 0.85 meters and subtract it from 3.6. This equals 2.75.

A plank of wood is 3.6 meters long. 85 cm is sawn off.  How long is the remaining plank? 2.75 meters
