You could solve this by finding the area of the WHOLE figure and subtracting the piece that is taken out.
The area of the WHOLE rectangle is 18 * 15 = 270.
The area of the piece taken out is 9 * 10 = 90.
270 - 90 = 180 in^2

Let's separate this shape into three parts. A smaller rectangle at the top, and one at the bottom, and a bigger rectangle in the middle.

The smaller rectangle at the top:

The equation to find the area of a rectangle is
(a = area, l = lenght, w = width)

a = l · w
Put in the values
a = 18 · 3
a = 54

Since the smaller rectangle at the bottom has the same length and width, it has the same area. 

The bigger rectangle in the middle:

a = l · w
Put in the values
a = 8 · 9
a = 72

Now add all of the areas together to get the answer!

72 + 54 + 54 = 180

The answer is 180 :)

Hopefully this helps! If you have any more questions or don't understand, feel free to DM me, and I'll get back to you ASAP! :)

In the year 2015 Emily was three times as old asKaitlin. By the year 2021 Kaitlin will be half asold as Emily will be. How old w
weeeeeb [17]

In 2000 Emily was 9 years old.

Given that in the year 2015 Emily was three times as old as Kaitlin while by the year 2021 Kaitlin will be half as old as Emily will be, to determine how old was Emily on the year 2000 the following calculation must be performed:

  • 2015 = E = 3K
  • 2021 = E = 2K  
  • 24 /// 8 --- 30 /// 14
  • 18 /// 6 --- 24 /// 12
  • 18/6 = 3
  • 24/12 = 2
  • 2015 = Emily was 24 years old
  • 24 - (2015 - 2000) = X
  • 24 - 15 = X
  • 9 = X

Therefore, in 2000 Emily was 9 years old.

In a recent snail race, a snail traveled a distance of 1 1/6 inches in 2 minutes. Find the number if inches traveled per minute
Alecsey [184]

Answer:

For inch/min =0.9167 inch/min

For min/inch = 1.0908 min/inch

Step-by-step explanation:

The snail in the race traveled 11/6 inches in 2 minutes.

The number of inches per minute is equal to = (11/6)/(2)

= 11/12

=0.9167 inch/min

The number of minutes per inch is equal to = 1/(inch per min)

= 1/0.9167

= 1.0908 min/inch

Minutes per inch is gotten by taking the inverse of inch/min or dividing the number of minutes by number of inches

Avery has 2 blue marbles. One sixth of Avery's marble are blue. How many marbles does Avery have?
katrin [286]

Answer:

Step-by-step explanation:

The equation

2 = (1/6)x represents this situation.

2 is 1/6 of some value.  In this case, the value is the total number of marbles.  2 represents 1/6 of the total number of marbles is how to read that equation in context.  Solve that equation for x

2 = (1/6)x  

12 = x           (multiply both sides by 6 to get rid of the fraction)
