Determine the circumference of a circle with a radius of 4 units.
16 units
8 units
32 units
4 units
Final answer:
The circumference of a circle with a radius of 4 units can be calculated using the formula C = 2πr, which equals approximately 25.13 units when using π as 3.14159.
Explanation:
To determine the circumference of a circle with a radius of 4 units, we need to use the circumference formula:
C = 2πr
Where C represents the circumference, π (pi) is approximately 3.14159, and r is the radius of the circle.
π is a special mathematical constant that represents the ratio of the circumference of any circle to its diameter, and for most practical calculations, it can be approximated as 3.14. Therefore, plugging the radius (4 units) into the formula we get:
C = 2 x 3.14159 x 4
C = 8 x 3.14159
C = 25.13272 units
We can round this answer to two decimal places for simplicity, obtaining:
C = 25.13 units
So, the circumference of a circle with a radius of 4 units is approximately 25.13 units.
The circumference of a circle with a radius of 4 units is approximately 25.12 units.
Explanation:The circumference of a circle can be found using the formula C = 2πr, where C is the circumference and r is the radius. In this case, the radius is given as 4 units, so we can substitute that value into the formula to find the circumference.
C = 2π(4) = 8π units.
Since π is approximately 3.14, we can approximate the circumference as:
C ≈ 8 x 3.14 = 25.12 units.
Therefore, the circumference of the circle with a radius of 4 units is approximately 25.12 units.
If a cube shaped box has a volume of 1331 cubic inches how tall is the box.
Answer: Cube is 11 inches tall
Explanation:
Cube has all edges the same length . The volume of a cube is multiplying the length of any edge, height and width of the cube.
Volume of cube = length * width * height
We know that length = width = height = s
So, Volume of cube = s*s*s
= s³
In given question:
Volume of the cube = 1331 cu in.
s³ = 1331
take cube root both the side
s = ∛1331
s = ∛(11*11*11)
s = 11 inch
So, height of the cube = 11 inches

the length of a rectangle is 8 feet more than its width the area of the rectangle is 84 square feet find its length and width.
Answer:
breath = 6ft
length = 14ft
Step-by-step explanation:
Area of a rectangle = length x breath
Area = 84ft²
Since length is 8feet more than breath.
Let assume a breath is y.
i.e
breath = y
length = y + 8
Area = 84
84 = y * (y+8)
84 = y² + 8y
y² + 8y - 84 = 0
quadratic equation
y ( y - 6 ) + 14 ( y - 6 )
(y + 14 )( y - 6 )
So to find y
y + 14 = 0
y = -14
Or
y - 6 = 0
y = 6
We will you the positive value of y, because we can not have a negative value for measurements ( length or breath)
Therefore
breath = y
breath = 6ft
length = y + 8
length = 6 + 8 = 14ft
what is the inverse of the function below f(x) =x/5 -2
Answer:
[tex]y=5x+10[/tex]
Step-by-step explanation:
[tex]f(x)=\frac{x}{5} -2[/tex]
To find the inverse of the function we do the following steps
Replace f(x) with y
[tex]y=\frac{x}{5} -2[/tex]
Replace y with x and x with y
[tex]x=\frac{y}{5} -2[/tex]
Solve the equation for y
Add 2 on both sides
[tex]x+2=\frac{y}{5}[/tex]
Now multiply by 5 on both sides
[tex]5(x+2)=y[/tex]
Now distribute 5 inside the parenthesis
[tex]5x+10= y[/tex]
[tex]y=5x+10[/tex]

One jug of plant food treats an area of 135 square ft. How many jugs Would be needed to treat an area of 165 square yards (try writing equation)
To treat an area of 165 square yards, you would need 11 jugs of plant food.
Explanation:To find out how many jugs would be needed to treat an area of 165 square yards, we need to convert the area to square feet and then divide by the area treated by one jug of plant food.
1 square yard = 9 square feet, so 165 square yards = 165 × 9 = 1485 square feet.
Now, since one jug treats an area of 135 square feet, the number of jugs needed is 1485 ÷ 135 = 11 jugs.

1. Susan’s art class is 9 hours long. How long is her class in minutes?

3. A cook needs 4 cups of vegetable broth for a soup recipe. How much is this in pints.
4. Last month, a coral reef grew 9000 millimeters taller. How much did it grow in meters?
Susan's art class is 540 minutes long. Frank drinks 3 cups of milk a day. The cook needs 2 pints of vegetable broth for their recipe. The coral reef grew 9 meters taller.
To solve these measurement conversion problems, we'll work through each one step by step:
Susan's art class is 9 hours long. Since there are 60 minutes in an hour, her class is 9 hours × 60 minutes/hour = 540 minutes long.To convert Frank's milk consumption from pints to cups, we use the fact that 1 pint is equal to 2 cups. So, 1 ¹/₂ pints is the same as 1.5 × 2 cups, which equals 3 cups.When converting the 4 cups of vegetable broth to pints, we remember that 2 cups is equivalent to 1 pint. Therefore, 4 cups is equal to 2 pints.The coral reef grew by 9000 millimeters. To find this growth in meters, we use the conversion that 1000 millimeters is equal to 1 meter. Therefore, it grew by 9000 mm × (1 m / 1000 mm) = 9 meters.Big Reward! (Answer the right answer not just comment).
2(5x-4)=ax+b
Find a value for a and b so that the solution is
A. Has one solution
B. Has no solutions.
C. Infinite Solutions
Answer:
A. a = 0, b = 2
B. a = 10, b = 0
C. a = 10, b = -8
Step-by-step explanation:
2(5x-4)=ax+b
10x - 8 = ax + b
When a = 10, b = -8
This equation becomes true for all x. Hence infinite solutions.
When a = 10, b is not -8,
This equation has no solution.
One possible combination could be:
a = 10, b = 0
When a is not 10,
The two sides of the equation become two non parallel lines which will intersect at one point.
A combination could be:
a = 0, b = 2
