Answer:
2r
Step-by-step explanation:
You suppose that the radius of a larger circle = r
so diameter = r*2 = 2r
aint really sure tho
Answer:
2R
Step-by-step explanation:
The formula to find the diameter states the relationship between the diameter and the radius. The diameter is made up of two segments that are each a radius. Therefore, the formula is: Diameter = 2 * the measurement of the radius. You can abbreviate this formula as d=2r.

Each tile may be used once or not at all. And part b plz help
Each pound of bananas costs $1.49 when buying 10 pounds, and $1.51 when buying 8 pounds.
What is Pound?The standard unit of money in the United Kingdom, equivalent to 16 ounces (or 0.454 kilograms), is used in most English-speaking countries. For more information, see measure. also known as the pound sterling.
According to question:Let the cost per pound of bananas be represented by x. Then we can set up the following system of equations:
[tex]10x &= 14.90 \\8x &= 12.08[/tex]
Solving for $x$ in each equation, we get:
x = 14.9/10 = 1.49
x = 12.08/8 = 1.51
Therefore, each pound of bananas costs $1.49 when buying 10 pounds, and $1.51 when buying 8 pounds.

Apples cost $1.99 per pound. How much do 314 pounds of apples cost? $ How much do x pounds of apples cost? $ Clare spent $5.17 on apples. How many pounds of apples did Clare buy? pounds
Answer:
1. $624.86
2. 1.99x
3. 2.6 pounds
Step-by-step explanation:
1. Multiply 1.99 by 314 to get 624.86
2. With the equation 1.99x, you can substitute any variable into it and it will hold true.
3. Divide 5.17 by 1.99, the price, and you get 2.597 pounds, which rounds to 2.6

Given the functions f(x) = x^5 and g(x) = 8.2^x, which of the following

Which of the following constants can be added to x^2- 3x to form a perfect square trinomlal?
A. 2 1/4
B. 1 1/2
C. 4 1/2
Answer:
A 21/4
Step-by-step explanation:
When forming a perfect square trinomial you need to "complete the square".
All of the steps to completing the square when solving an equation:
1. The leading coefficient must be 1.
2. Divide b by 2.
3. Square (b/2)
4. Add (b/2)^2 to both sides to keep the polynomial balanced.
5. You can now write the perfect square trinomial and solve.
x^2 - 3x
-3/2
(-3/2)^2 = 9/4 = 2 1/4

Jennifer's grandma bought her a $50 savings bond when she was born. When Jennifer is 30 years old, the bond will have earned 110% in interest. How much will the bond be worth when Jennifer is 30 years old?
Answer:
105$
Step-by-step explanation:
We are told that she starts with 50$
We are also that after 30 years she earns 110% on interest
Given this information we need to find the value of the bond after the 30 years
To do so we take 110% of the initial value (50$) and add that to the initial value
So the answer = 110%(50) + 50
110%*50=55
55+50=105
So in 30 years the bond will be worth 105$

Matteo is working two jobs, making $15 per hour at the movie theater and $18 per hour washing cars. Last week Matteo worked a total of 30 hours and earned a total of $480. Determine the amount of hours Matteo worked at the movie theater and the cash wash.
Answer:
movie theatre = 20 hours
car wash = 10 hours
Step-by-step explanation:
this would be solved using simultaneous equation
let a = hours worked in theatre
b = hours spent wash cars
15a + 18b = 480 eqn 1
a + b = 30 eqn 2
multiply eqn 2 by 15
15a + 15b = 450 eqn 3
subtract 1 from 3
3b = 30
b = 10 hours
substitute for b in eqn 2
a + 10 = 30
a = 20 hours

Answer:
28in, 195in, 197in
Step-by-step explanation:
There's no "supereasy" way to solve it, except by computation or approximation.
e.g. 2 3 6 couldn't work, because 2+3 < 6 so it's not even a triangle
125^2 cannot equal 122^2 + 30^2, because 125^2 is odd and 122^2 and 30^2 are even
23^2 + 18^2 = 529 + 324 < 900 < 31^2
So it has to be the last one, and after verification we find it checks out and 28^2 + 195^2 = 197^2

What is the area of sector with a central angle of 160 and a diameter of 5.8 m? Round the answer to the nearest tenth.
A) 8.1 m^2
B) 4.0 m^2
C) 46.0 m^2
D) 11.7 m^2
Answer:
[tex]A=11.7\ m^2[/tex]
Step-by-step explanation:
Given that,
Central angle, [tex]\theta=160^{\circ}[/tex]
Diameter,d = 5.8 m
Radius, r = 2.9 m
We need to find the area of sector. The formula for the area of sector is given by :
[tex]A=\dfrac{\theta}{360}\times \pi r^2\\\\=\dfrac{160}{360}\times 3.14\times 2.9^2\\\\=11.7\ m^2[/tex]
So, the area of a sector is equal to [tex]11.7\ m^2[/tex].
