If x^2 + y^2 = 9, x^2 + y^2 = 3^2 = r^2.  The radius is 3 and the diameter is twice that, or d = 6 units

Answer:

8x+4 and 2x-4

Step-by-step explanation:

We are going to use factoring to make equivalent expressions. What you do is you take the number next to the parenthesis and multiply it with what is inside the parenthesis. So it would be 8x+4 and 2x-4. Hope this helps! :)

Answer:

The first 100 whole numbers are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25,26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, ...

Step-by-step explanation:

The whole numbers between 20 and 50  are 20, 24, 28, 32, 36, 40, 44, 45, 48.

A whole number is defined merely as any positive number that does not consider a fractional part or any decimal part of the numbers.

For example, the numbers 0, 1, 2, 3, 4, 5, 6, and 7 are all whole numbers. Numbers such as -9, 6.2, or 2 ½ are not whole numbers.

Therefore, the whole numbers that are on the gap between of 4 between 20 and 50 are the  20, 24, 28, 32, 36, 40, 44, 45,  48.

Answer:

77.5 degrees

Step-by-step explanation:

sin(90)/42=sin(?)/41

sin(90)/42 times 41=0.9761904

sin^-1(0.9761904)=77.47209456 degrees

Answer:

90 - 43 = x

Step-by-step explanation:

Answer: 47

Step-by-step explanation:

Dude just subtract 43 from 90, since you are given a 90 degree angle.

But if you need the equation: 43+x-7=90

add 43 and (-7) which gives us 36

new equation is now: 36+x=90

move the 36 to the other side

x=54

now plug it in x(54)-7=47

The sale price 's' of a book is $3.50 less than the original price 'p'. This situation is represented by the given equation s = p - 3.5.

Two or more expressions with an Equal sign is called as Equation.

The given equation is s = p - 3.5, where 's' represents the sale price and 'p' represents the original price of a book.

The equation shows that to get the sale price 's', the original price 'p' is reduced by $3.50.

If the sale price 'p' of a book is $3.50 less than the original price 's', then we can rewrite the equation as p = s + 3.5.

This situation is not represented by the given equation.

If the sale price 's' of a book is $3.50 more than the original price 'p', then the equation would be s = p + 3.5.

This situation is also not represented by the given equation.

Hence, the sale price 's' of a book is $3.50 less than the original price 'p'. This situation is represented by the given equation s = p - 3.5.

Answer:

[tex]\overline {DC}[/tex] = 7

[tex]\overline {BD}[/tex] = √35

[tex]\overline {AB}[/tex] = 2·√15

Step-by-step explanation:

Please find attached the drawing of right triangle ABC created with MS Visio

Let 'x' represent [tex]\overline {BD}[/tex] let 'y' represent [tex]\overline {DC}[/tex], and let 'z' represent [tex]\overline {AB}[/tex], we get;

5² + x² = z²...(1)

x² + y² = (2·√21)² = 84

x² + y² = 84...(2)

84 + z² = (5 + y)²...(3)

From equation (1), we have;

x² = z² - 5²...(4)

From equation (2), and equation (4), we have;

x² + y² = 84 = (z² - 5²) + y² = 84

∴ z² = 84 - y² + 5² = 109 - y²

z² = 109 - y²...(5)

From equation (3), and equation (5), we have;

84 + z² = (5 + y)² = 84 + (109 - y²) = (5 + y)²

84 + (109 - y²) = (5 + y)²

(5 + y)² - (84 + (109 - y²)) = 0

2·y² + 10·y - 168 = 0

y² + 5·y - 84 = 0

y = (-5 ± √(5² - 4 × 1 × (-84)))/(2 × 1)

y = 7, or y = -12

We note that 'y' is a natural number, therefore, the correct option of the two options is y = 7

y = [tex]\overline {DC}[/tex] = 7

From equation (2), we have;

x² + y² = 84

x² = 84 - y² = 84 - 7² = 35

x = √35

x = [tex]\overline {BD}[/tex] = √35

z² = 109 - y²

∴ z² = 109 - 7² = 60

z = √60 = 2·√15

z = 2·√15

z = [tex]\overline {AB}[/tex] = 2·√15.

Answer:

7 cm

Step-by-step explanation:

Area of a parallelogram formula:

[tex]A=bh[/tex] where b is the base length and h is the height

Plug in known values (A=112, b=16 and h=x)

[tex]112=16x[/tex]

Divide both sides by 16 to isolate x

[tex]\frac{112}{16} = \frac{16x}{16}\\7=x[/tex]

Therefore, x is equal to 7 cm.

Answer: 22,000 * 1.25^ x

Step-by-step explanation:

The number of pages grows at 25% every week. This number is based on the previous week's number of pages so the increase in page number is being compounded.

Use the future value equation to determine the number of pages after x weeks.

FV = Amount * ( 1 + rate of increase) ^ time

= 22,000 * ( 1 + 25%) ^ x

= 22,000 * 1.25^x

Answer:

<B = 95degrees

<D = 137 degrees

Step-by-step explanation:

From the given diagram, the sum of the adjacent sides of the trapezoid is 180degrees. Hence;

<A +<B = 180

85 + <B = 180

<B = 180 - 85

<B = 95degrees

Similarly

<C + <D =180

43 + <D = 180

<D = 180 - 43

<D = 137 degrees

Answer: 49

Step-by-step explanation:

If 72% of the stamps he collected were

foreign, the percentage of the other stamps will be: = (100% - 72%) = 28%

Since the total number of stamps collected are 175, the number of other stamps collected will be:

= 28% of 175

= 28% × 175

= 28/100 × 175

= 0.28 × 175

= 49

Therefore, he collected 49 other stamps that were not foreign
