So you would need to subtract the area of the whole rectangle-the white area of the rectangle
The formula for area is a=bh
the area of the whole rectangle is a=8*5, so 40units squared, and the are of the non-shaded region is a=3*2 so 6 units squared
in order to find the shaded region, do 40-6
34 units squared is your answer
hope this helps!:)

8x5 = 40
3x2 = 6

40 - 6 = 34

answer:
area of shaded = 34

Roxanne has 1/2 as many beads as Sherie. The number of beads Sherie has is 4/5 that of ting ting's. Ting Ting has 165 beads. How

Rom4ik [11]

Step-by-step explanation:

T = beads of Ting Ting = 165

S = beads of Sherie.

R = beads of Roxanne.

S = 4/5 × T = 4/5 × 165 = 4 × 33 = 132 beads

R = 1/2 × S = 1/2 × 132 = 66 beads

Ting Ting has therefore 165 - 66 = 99 more beads than Roxanne.

Solve x – 7 > –8.

IgorC [24]

Question 1.

x - 7 > - 8

Adding 7 to both sides, we get:

x - 7 + 7 > - 8 + 7

x > -1

Thus the answer to the inequality is option Fourth.

Question 2.

A number exceeds 66. Let that number be x. The number exceeds 66 means that the number is larger than 66. So in form of an expression we can write the inequality as:

x is greater than 66

x > 66

So, option 1st gives the correct answer.

Question 3.

The tiles are square shaped and area of a square can be calculated as the square of its Length.

Area of square = (Length)²

If we are given the Area, we can find the length as:

Length = $\sqrt{Area}$

For Tile A, the length will be:

$Length= \sqrt{9}=3$
So length is a Rational number

For Tile B, the length will be:

$Length= \sqrt{25}=5$
So length is a Rational number

For Tile C, the length will be:

$Length= \sqrt{34}$
So, Length is not Rational.

For Tile D, the length will be:

$Length= \sqrt{76}$
Length is not Rational

Thus, the lengths of Tile A and Tile B are rational only.

Therefore, the correct answer is 1st option

John and Andrew have £3.40 between them. John has £1.20 more than Andrew. John has £u and Andrew £v

Dahasolnce [82]

In the given question, there are several information's of immense importance and they can be used to find the necessary answers. It is already given that John and Andrew have 3.40 pound together. It is also given that John has 1.20 pound more than Andrew. It is also assumed that John has"u" pound and Andrew has "v" pounds.
Then we can write the two equations as
u + v = 3.40
u = v + 1.20
To find the values of u and v, we can replace the u in the first equation with the value of u in the second equation. Then
u + v = 3.40
(v + 1.20) + v = 3.40
2v + 1.20 = 3.40
2v = 3.40 - 1.20
2v = 2.2
v = 2.2/2
= 1.1
Now we replace the value of v in the first equation to find the value of u.
u + v = 3.40
u + 1.1 = 3.40
u = 3.40 - 1.1
u = 2.3
