Calculate the area of this circle. Type the formula you used and your steps.

Answer:

x = 11.1

Its a right angle triangle with the values of its adjacent and hypotenuse given so cos is used.

Answer:

It would be C or 56.70

Answer:

Step-by-step explanation:

1). 3x(2x - 2) = 3x(2x) + 3x(-2) [By distributive property]

2). x²(_ + 5x - 3) = (3)x² + x²(5x) + x²(-3)

3). _(x² - 3x + _) = x(x²) - (x)(-3x) + (x)(2)

4). (2x + 9)(x + 2) = 2x(x + 2) + 9(x + 2)

                            = 2x² + 4x + 9x + 18

                            = 2x² + 13x + 18

5). (z - 4)(2z + 1) = z(2z + 1) + (-4)(2z + 1)

                         = 2z² + z - 8z - 4

                         = 2z² - 7z - 4

Answer:

That means from 80 to 90, there are 5 odd numbers.

That also means, in between 10 numbers, there are 5 odd numbers.

It's fair enough to believe now that in the next 20 numbers—80 to 100—there will be 10 odd numbers.

Another pattern.

And the conclusion: from 80 to 180, there are 100 numbers. Therefore, There Will Be 50 Odd Numbers.

There are 50 odd numbers between 80 and 180.

Step-by-step explanation:

Answer:

An odd number between 90 and 180 is 91

Answer:

[tex]\frac{3x^2}{(x+2)(x-4)}[/tex]

Step-by-step explanation:

Before adding the fractions we require them to have a common denominator.

Multiply numerator/ denominator of first fraction by x - 4

Multiply numerator/ denominator of second fraction by x + 2

= [tex]\frac{x(x-4)}{(x+2)(x-4)}[/tex] + [tex]\frac{2x(x+2)}{(x+2)(x-4)}[/tex] ← expand and simplify numerators, leaving common denominator

= [tex]\frac{x^2-4x+2x^2+4x}{(x+2)(x-4)}[/tex]

= [tex]\frac{3x^2}{(x+2)(x-4)}[/tex]

Answer:

70

Step-by-step explanation:

Okay so 10%=0.1. let's say that mystery number is x

that means that 0.1x=7

now to solve for x we need to multiply both sides of the equal sign by 10

so.....x=7*10=70        

Answer:

B) 22

Step-by-step explanation:

AC = BD

6x+10 = 10x+2

simplify:

subtract 6x and 2 from both sides:

4x = 8

x = 2

then:

AC = 6(2)+10 = 22

Answer:

Answer:

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try!

Answer:

218.665

Step-by-step explanation:

Separate by shape, find the areas of the triangles first, so (10.1 x w)/2 To get the missing side you do 30.5-21.4=9.1. then divide that by 2 because you have 2 lines (triangles) that aren't part of the 21.4. After you find the area for the one triangle (10.1 x 4.55)/2=22.9775, multiply by 2 to get the combined area of both triangles. Next step is to find the area of the rectangle, which is just 21.4 x 30.5=216.14. Add all the areas, 45.955+216.14=262.095. Last step is to subtract the area of the shaded region, the rhombus, which is just diagonal x diagonal / 2. so (8.6 x 10.1)/2=43.43. 262.095-43.43=218.665.

Answer:

x<20

Step-by-step explanation:

Building linear functions for each situation, the inequality is:

[tex]18x + 100 < 15x + 160[/tex]

------------------

Choice A:

Thus, the cost of inviting x guests is given by:

[tex]C_a(x) = 18x + 100[/tex]

Choice B:

Thus, the cost of inviting x guests is given by:

[tex]C_b(x) = 15x + 160[/tex]

A cost less than B, thus, the inequality is:

[tex]C_a(x) < C_b(x)[/tex]

[tex]18x + 100 < 15x + 160[/tex]

Answer:The answer is 100-25pi

Step-by-step explanation:

quarter circles = full circle

Full circle area = pie r2

Square area = s2

In this case, the side of the square is twice the radius of the circle

Answer:

8 is the answer

Step-by-step explanation:

the equation is r = C/2*3.14

2*3.14=6.28

Because your C is 50  you do 50/6.28 and when you do that you get 7.962 (rounded) and then we round for the whole # so 8.

Answer:

1) The car can travel 623.3 km with 85 liters of petrol.

2) The car owner has to pay $303.8.

Step-by-step explanation:

1) The distance traveled with 85 L of petrol can be found as follows:

[tex] d = \frac{330 km}{45 L}*85 L = 623.3 km [/tex]

Hence, the car can travel around 623 km with 85 liters of petrol.

2) If the liter of petrol costs $2.25, then the amount of petrol that the car owner has to pay to travel a distance of 990 km is:

[tex]x = \frac{\$ 2.25}{1 L}*\frac{45 L}{330 km}*990 km = \$ 303.8[/tex]

Therefore, the car owner has to pay $303.8.

I hope it helps you!
