Answer:

Area the figure = 45 - 9 = 36 units² ⇒ last answer

Step-by-step explanation:

"I have added screenshot of the complete question as well as the diagram"

All the angles of the figure are right angles

From the attached figure: we can find the area of the figure by subtracting the area of the cutting part from the area of the rectangle of dimensions 9 units and 5 units

∵ All the angles of the figure are right angles

∴ We can consider that the figure of dimensions 9 units and 5 units

as a rectangle

∵ Area of any rectangle A = L × H , where L, H are the dimensions

of the rectangle

∵ L = 9 units and H = 5 units

∴ Area of the rectangle = 9 × 5 = 45 units²

- The dimensions of the cutting part are 3 units and

[9 - (2 + 4) = 9 - 6 = 3 units]

∴ The cutting part is a square

∵ Area any square = S², where S is the length of the side of the square

∵ S = 3 units

∴ The area of the cutting part = 3² = 9 units²

∵ Area of the figure = area rectangle - area square

∵ Area the rectangle = 45 units²

∴ Area the square = 9 unit²

∴ Area the figure = 45 - 9 = 36 units²

Fill in the other coordinate for the line 3x-5y=2: (4, ) is the answer 2

Anton [14]

Step 1
plug in 4 for X
3(4)-5y=2
12-5y=2
Step 2
-12 (both sides)
-5y=-10
Step 3
divide both by -5
y=2

the answer is
the coordinates are (4,2)

Grace deposits $1000 in a mutual fund earning 9.25% annual interest, compounded monthly. Write an exponential function that mode

Serggg [28]

First, we calculate for the effective interest given the annual interest and the condition that it is compounded monthly.

Ieff = (1 + 0.0925/12)^12 – 1 = 0.09652

The equation that would best represent the value of Grace’s money after x years is equal to,

An = ($1000)(1.09652)^x

Where x is the number of years

Jon ran around a track that was 1/8 of a mile long,he ran around the track 24 times,how many miles did Jon run

Sonbull [250]

Hi there

So, if the track is 1/8 of a mile, let's call every lap a "one-eighth mile" run. We know John ran 24 laps, or that he ran 24 "one-eighth miles," just consecutive, one right after another. Let's stop worrying about rates or tricks or math for a second, and just ask: how many real miles is 24 "one-eighth" miles? We know it's less than 24---a lot less, since you have to go around 8 times just to get to 1 mile. Well wait, if we go around 8 times, we get 1 mile. That means if we go around 28, or 16 times, we get 2 miles; And let's just think to the next full mile---if we go 38, or 24 times, we get 3 miles. He did go around 24 times, so he must have run 3 miles on a 1/8 track.

Division and multiplication are inverses of each other. So we solved this by looking for an intuition for how many full miles corresponded to how many laps, with a bunch of steps of multiplication. But you can cut right to the chase and solve it faster with division---24 laps * 1 mile per 8 laps, means:

total distance = 24 Lap (1 mi / 8 Lap) total distance = 24/8 total distance = 3

On Mondays, Wednesdays, and Fridays, Luke packs his lunch. On Tuesdays and Thursdays, Luke buys his lunch. Draw a non-numeric pa

Lesechka [4]

The non-numeric pattern that shows the pattern of Luke's lunch for two weeks is P B P B P P B P B P

<h3>What are patterns and sequence?</h3>

Patterns are simply the rules that guides the formation of a numeric or non-numeric sequence

From the question, we have the following highlights

Pack lunch (P): Mondays, Wednesdays, and Fridays.
Buy lunch (B): Tuesdays and Thursdays,

Using the above representation, the non-numeric pattern that shows the pattern of Luke's lunch for two weeks can be represented as P B P B P P B P B P
