I need help with number 3 and 4

The white area of the square is equal to 55.04cm²

To calculate the white area of the square we must perform the following operations.

To calculate the total area of the square, we multiply the side length by the base.

Then we must calculate the area of the pink circles, for this we use the following formula:

Then we proceed to replace the values of the number pi and the radius:

Now we multiply the area of the circle by four to find the total area occupied by the four circles inside the square.

50.24cm² × 4 = 200.96cm²

Finally we subtract the area of the 4 circles from the total area of the square and the result will be equivalent to the white area of the square.

256cm² - 200.94cm² = 55.04cm²

You may see the "slant" referred to as a "hypoteneuse", as the shape created by the line of height(or altitude) is a right triangle. Given the base of the triangle and the "slant" or "hypoteneuse", format the equation (a²+b²=c²)-where a represents the height(altitude), b represents the base, and c represents the slant(hypoteneuse)- to fit your needs:

c²-b²=a². From this point, find the square root(√) of a. If it cannot be simplified further, then (√a) is your solution.

74.94×10^3= 74940 because the number 10³ has 3 zeros when it is written without an exponent.

Step-by-step explanation:

when times 10, you move the decimal point to the right.

Answer:

74.94×103=7718.82=7.7×10³

Answer:

(-2x+4)+2(2x+1) = 2x+6

2(3x+5)-4(x-1) = 2x+6

2(x-7)+(8x+20) = 10x+6

They should be the answers if the simplified forms can be used twice.

The number of ways he can display the stamps as follows:

Here we find the factors of 32

i.e.

= 1 × 32 represent 1 row, 32 stamps each

= 2 × 16 represent 2 rows, 16 stamps each.

= 4 × 8 represent 4 rows, 8 stamps each.

= 8 × 4 represent 8 rows with 4 stamps each

= 16 × 2 represent 16 rows with 2 stamps each

= 32 × 1 represent 32 rows with 1 stamp each

So in 6 ways he can displayed

Answer:

  = 1/279,936 ≈ 3.5722·10^-6

Step-by-step explanation:

You can ask your calculator to give you the answer. It may display something like ...

  g(-1.75) = 3.57224508459·10^-6

You know the negative exponent means this is the reciprocal of ...

  1296^1.75 = 279,936

So, you can also write the answer as ...

  g(-1.75) = 1/279936

Since the value of x is given as a decimal, it is appropriate to give the answer as a decimal.

Answer: 30

Step-by-step explanation:

Answer:

the answer is 650

Step-by-step explanation:

use the formula, a^2 + b^2 = c^2

so 25^2 = 625

and 5^2 = 25

added, 650.

Answer: 16.6

Step-by-step explanation:

a² + b² = c²

7² + b² 18²

49 + b² = 324

Subtract 49 from both sides

b² = 275

√b² = √275

b = 16.583

16.583 ≈ 16.6

Answer:

steps below

Step-by-step explanation:

Step 1: Cot A / (1+cot A) * Cot B / (1+cot B )

= (Cot A  * Cot B) / ((1+cot A) *(1+cot B ))

= (Cot A  * Cot B) / (1+cot A+cot B+cot A cot B)

= (Cot A  * Cot B) / ((1+cot A+cot B)+ (cot A cot B))     : a

Step 2: (cot A * cot B -1) / (cot A + cot B) = cot (A+B) = cot 225° = 1  (formula)

            cot A * cot B -1 = cot A + cot B

            cot A * cot B  = 1 + cot A + cot B       (substitute a)

Step 3:

Cot A / (1+cot A) * Cot B / (1+cot B )

= (Cot A  * Cot B) / ((cot A * cot B)+ (cot A * cot B))

= (Cot A  * Cot B) / (2 * (cot A * cot B))

= 1 / 2

= 0.5

The measure of the angle x is 32 degree after applying the sin law of triangle.

The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

We have a triangle given in the diagram.

To find the measure of the angle x we must apply the sin law of triangle.

[tex]\rm \dfrac{17}{sin116} = \dfrac{10}{sinx}[/tex]

Sinx = 10(sin116)/17

Sinx = 0.528

x = 31.91 ≈ 32 degree

Thus, the measure of the angle x is 32 degree after applying the sin law of triangle.
