A rectangle is divided into 15 identical squares arranged in three rows. What is the perimeter of the rectangle, in centimeters,
lozanna [386]

Answer:

48 cm

Step-by-step explanation:

Here, we are concerned with finding the perimeter of the rectangle.

Now, since the square has an area of 9 cm^2, it means that the squares has a side of 3 cm each since the area of a square is s^2

So now, there are 5 squares in a row, meaning in a straight stretch , left to right or right to left, there are 15 squares. So the total length here is 5 * 3 = 15 cm

Now, moving column-wise, from top to bottom, since we have 3 rows, what this means is that per column of the rows, there are 3 squares. So the total length here becomes 3 * 3 = 9 cm

So we have a rectangle 9cm by 15cm

The perimeter is thus 2(L + B) = 2(15 + 9) = 2(24) = 48 cm

Kareem drove 240 miles using9 gallons of gas. At this rate, how many gallons of gas would he need to drive 216 miles?
ipn [44]

Step-by-step explanation:

240 miles = 9 gallons of gas

1 mile = 9/240

= 3/80 (0.0375) gallons of gas

216 miles = 3/80 (0.0375) × 216

= 8.1 gallons of gas

Plot a point C that divides the segment into the<br> ratio AC:AB= 3/4
aalyn [17]

Given :

A graph .

To Find :

A point C that divides the segment into the  ratio AC:AB= 3/4 .

Solution :

From the graph we can see that point A and B are ( 1 , -2 ) and ( 5 , 6 ) respectively .

Now , we know point which divide a line segment with end point (x_1,y_1) and (x_2,y_2) in m : n is :

x=\dfrac{mx_2+nx_1}{m+n}\ ,\  y=\dfrac{my_2+ny_1}{m+n}

Putting all given values we get :

x=\dfrac{3(5)+4(1)}{3+4}\ ,\  y=\dfrac{3(6)+4(-2)}{3+4}\\\\x=\dfrac{19}{7}\ ,\ y =\dfrac{10}{7}

Therefore , point C is (\dfrac{19}{7},\dfrac{10}{7}) .

Hence , this is the required solution .

lwh=V

(5)(2)(1.2)=V

10(1.2)=V

12=V
