I'm guessing 3 rounds means 3 times around?
diameter = 280
circumference = dπ = 280π
280π x 3 = 840π
If you want it rounded it's about 2638.94 :)

30 = 2.5x
What is x equal to? Help please!
Answer:
x = 12
Step-by-step explanation:
30=2.5x for you to find the value of x divide both side by 2.5.
30 = 2.5x
2.5 2.5
12 = x
To check your answer, substitute the value of x.
30 = 2.5 (12)
30 = 30
If it is equal, your answer is correct!
x is equal to 12 in the given equation 30 = 2.5x.
To find the value of x in equation 30 = 2.5x, we can solve for x by isolating it on one side of the equation.
Given equation: 30 = 2.5x
To isolate x, we need to divide both sides of the equation by 2.5:
30/2.5 = (2.5x)/2.5
Simplifying this equation, we have:
12 = x
Therefore, x is equal to 12.
By dividing both sides of the equation by 2.5, we effectively cancel out the multiplication of x by 2.5, leaving us with the value of x. So, when 12 is substituted for x in the original equation, 2.5 times 12 equals 30, confirming that the value of x = 12 satisfies the equation.
Hence, x is equal to 12 in the given equation 30 = 2.5x.

Daniel bought a total of 8 pounds if peanuts and cashews. Peanuts, p, cost $2 per pound and cashews, c, cost $5 per pound. The total amount Dani spent on the peanuts and cashews was $25. Which system of equations could be solved to find how many pounds kf peanuts dani bought
A.{2p+5c=25
p+c=9
B.{5p+2c=25
p+c=8
C.{2p+5c=8
p+c=25
D.{2p=8
5c=25
Answer:
I believe the answer is C.
Step-by-step explanation:
given we have peanuts to be $2 per pound, and cashews $5 per pound. If we use the equation p+c=25 then p would be (2×10=20), and c would be (5×1=5). then, to solve the problem we would do p+c=25 which p would be 20, and c would be 5, then add and it would equal 25.
How do I graph
y=-1/2x-1
Answer:
Step-by-step explanation:
Find the x and y intercept, and determine the slope.
X-intercept:
[tex]0=-\frac{1}{2}x-1\\1=-\frac{1}{2}x\\x=-2[/tex]
It crosses the x-axis at x = -2
Y-intercept:
[tex]y=-\frac{1}{2}(0)-1\\y=-1[/tex]
It crosses the y-axis at y = -1
Slope:
y = mx + b
m = slope = -1/2
The graph of the linear equation y = -(1/2)x - 1 is plotted.
Given data:
To graph the equation y = -1/2x - 1, use the slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.
So, the slope is -1/2, and the y-intercept is -1.
To plot the graph, follow these steps:
Plot the y-intercept:
Start by plotting the point (0, -1), which represents the y-intercept.
Use the slope to find another point: Since the slope is -1/2, use the rise and run method. From the y-intercept point (0, -1), move down 1 unit (negative 1) and then move to the right 2 units. This gives another point on the line, which is (2, -2).
Hence, the resulting graph should be a straight line sloping downwards from left to right and is plotted below.

Answer:
x = -0.441 and x = -2.359
Step-by-step explanation:
The given equation is :
[tex]2(5x+7)^2-13=33[/tex]
Adding 13 to both sides of the equation.
[tex]2(5x+7)^2-13+13=33+13\\\\2(5x+7)^2=46\\\\(5x+7)^2=23[/tex]
So,
[tex]5x+7=\sqrt{23}\\\\5x+7=\pm4.795\\\\5x=4.795-7, 5x=-4.795-7\\\\5x=-2.205, 5x = -11.795\\\\x=-0.441, x=-2.359[/tex]
So, the solution of the given equation is x = -0.441 and x = -2.359.
