Help please!!! Find the area of the shaded region. All angles are right angles

kompoz [17]

Answer:

Area = $147 m^{2}$

Step-by-step explanation:

The area of the shaded region is equal to the total area of the full square minus the area of the non shaded region.

The area of a rectangle is its base times its high

So A=b*a.

For the full square, A1= $9m*23m=207m^{2}$

For the non shaded square, A2 = $15m * 4m = 60m^{2}$

So the shaded area is A1-A2 = $207 m^{2} -60 m^{2} = 147 m^{2}$

adults say that they have cheated on a test or exam before. You randomly select six adults. Find the probability that the number

VLD [36.1K]

Answer: a. 1/6. b. 2/3. c. 5/6

Step-by-step explanation:

Number of adults randomly selected= 6

a. Finding the probability of adults that have cheated on an examination before is exactly 4.

The numbers are 1, 2, 3, 4, 5 and 6.

Probability of chosen exactly 4 will be 1/6 since 4 can only occur once.

b. More than 2means 3,4, 5 and 6.

Probability that the number of adults that have cheated on a test or exam is more than 2 will be:

4/6 = 2/3

c. At most 5 means 1,2,3,4 or 5

This will give 5/6

2. Seiji and Gavin both worked hard over the summer. Together they earned a total of $425. Gavin earned $25 more than Seiji. (a)

Alja [10]

Let Gavin be G
Let Seiji be S

G + S = 425
G = 25 + S

I can't really graph, but plug in some numbers to G and S that works in BOTH equations. Then graph it.

G + S = 425
G = 25 + S

(25 + S) + S = 425
2S + 25 = 425
2S + 25 (-25) = 425 (-25)
2S = 400
2S/2 = 400/2
S = 200

Seiji made 200 dollars

Now choose one of the equations to use (the easier the better) in this case i will choose this one:

G = 25 + S

pug in 200 into S (because that is how much Seiji made)

G = 25 + (200)
G = 225

Seiji made 200, Gavin made 225

200 + 225 = 425, which is the total amount the made

hope this helps
