The area of a circular pool cover is 314 square feet. Write and solve an equation to find the diameter of the pool cover. Use 3.14 for pie.
Step-by-step explanation:
First you need to know that A=πr^2
And the equation to find the diameter is d=2r
So, the equation is d=2√A/3.14
A is 314, so 314 divided by 3.14 is 10
So all that's left is d=2*10
And the diameter is 20 feet.
The diameter of the circular pool is 20 feet.
What is the diameter of the pool?A circle is a bounded figure which points from its center to its circumference is equidistant. The diameter is two times the value of the radius.
The first step is to determine the radius of the pool; Radius = √Area of a circle /π
Where :
π = pi = 22/7R = radius√314/3.14 = 10feet
Diameter 10 x 2 = 20 feet

Explain how to estimate the length of the whale using compensation
Answer:
Assuming that the longest blue whale on record was about 18 scuba divers in length and a scuba diver is 6 feet length, we want to estimate the length of the whale.
Length of the whale = 18*6
You can multiply mentally by using compensation. Substitute a number for 18 that is easy to multiply.
20*6 = 120
Now adjust. Subtract 2 groups of 6, or 12.
120 - 12 = 108
and that is the length of the whale in feet
Milli plans to rent a room for her birthday party for $40. The catering charge is $12 per person but there is no charge for Milli's meal since she is the guest of honor. If Milli has $100 to spend on her birthday party, how many guests can she invite?
she has 100
subtract 40 for renting the room
100-40 =60

if the pony is staked at the point (8,8) will the ponys path be interrupted by the fence
Answer:
Yes, it will be interruped by the fence.
Step-by-step explanation:
I am assuming you are dealing with a 10-foot long rope. The pony is making a circle with a raidus of 10 around the center, (8,8). If we were to draw a straight line from the center to the left that was 10 feet long, it would be horizontal to the stake, and it would go to (-2,8) (8-10,-8). Since the fence lies on the y axis, which is (0,y), but the coordinate (-2,8) has an x value that is less than 0, then the pony would crash into the fence.
this also works if you go down 10 feet to (8,-2) and the fence on the x axis has the coordinate (x,0)
Without additional details such as the length of the pony's tether and the location of the fence, it's not possible to definitively answer if the pony's path will be interrupted by the fence. This question involves understanding of coordinate systems and the concept of radius in geometry.
Explanation:The solution to this question depends on several factors not provided, including the length of the pony's tether and the location, shape, and size of the fence. The point (8,8) represents the pony's location in a two-dimensional coordinate system. If we know the length of the tether and the coordinates of the fence, we could then determine whether the pony's path would be interrupted by the fence.
For instance, if the pony's tether is 4 units long, then the pony can move in a circle (known as a radius) around the stake at (8, 8). If the fence is within that 4-unit radius, then the pony's path would be interrupted by the fence.
Without these additional details, we cannot provide a conclusive answer to this question. It's integral to have as much information as possible when working with coordinate systems and interpreting geometric movements and positions.

The length of a rectangular field is 30 more than twice its width. Write an expression in simplest form for the perimeter of the field in terms of its width w.
The expression for the perimeter of a rectangular field where the length is 30 more than twice its width, in terms of the width w, is 6w + 60.
The perimeter of a rectangle is given by the formula P = 2l + 2w, where l is the length and w is the width of the rectangle. According to the problem, the length (l) of the rectangular field is 30 more than twice its width (w). So we can express the length as l = 2w + 30.
Substituting this expression into the perimeter formula, we get:
P = 2(2w + 30) + 2w
Simplifying this expression, we get:
P = 4w + 60 + 2w = 6w + 60
So, the expression for the perimeter of the field in terms of its width w is 6w + 60, which is already in its simplest form.
calculate the total resistance for a 650 ohm, a 350 ohm, and a 1000 ohm resistor connected in series
The total resistance for the given resistors connected in series is 2000 ohms.
Explanation:To calculate the total resistance for resistors connected in series, you simply add up the individual resistances. In this case, the resistances are 650 ohm, 350 ohm, and 1000 ohm. So the total resistance would be:
Total Resistance = 650 ohm + 350 ohm + 1000 ohm = 2000 ohm

A rectangle has length of 5.25 cm and area of 44.625 cm. What does the length of the rectangle have to be?
Answer: 8.25 cm
Step-by-step explanation:
We know that the area of rectangle is given by :-
[tex]\text{Area}=\text{Length}\times\text{Width}[/tex]
Given : The length of rectangle: l= 5.25 cm
The area of rectangle:[tex] A=44.625\ cm^2[/tex]
Substitute the values of A and l in the formula given above, we get
[tex]44.625=5.25\times\text{Width}[/tex]
Divide 5.25 both sides , we get
[tex]\text{Width}=\dfrac{44.625}{5.25}=8.5[/tex]
Hence , the other length of the rectangle have to be 8.25 cm.

What are the slope and y intercept form for the graph of y+9x=-6
The slope of the graph for the equation y + 9x = -6 is -9, and the y-intercept is -6, which corresponds to the point (0, -6) on the y-axis.
The equation y + 9x = -6 can be re-written in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept. To find the slope and y-intercept from the given equation, we need to isolate y on one side. Here's how we do it step-by-step:
Start with the given equation: y + 9x = -6.Subtract 9x from both sides to isolate y: y = -9x - 6.The slope (m) is the coefficient of x, which is -9, and the y-intercept (b) is the constant term, which is -6. Thus, the slope is -9, and the y-intercept is the point (0, -6) on the y-axis.

what is one and one half divided by one and one sixth and what is three fourths divided by one and three eights (brainliest will be given)
Answer:
1. 3/7
2. 6/11
Step-by-step explanation:
One and one half divided by one and one sixth equals 1 2/7, and three fourths divided by one and three eights equals 6/11. To solve, convert mixed numbers to improper fractions, then multiply by the reciprocal of the divisor fraction.
To find out what one and one half divided by one and one sixth is, we first need to express these mixed numbers as improper fractions. One and one half is the same as 3/2 (since 1 + 1/2 = 2/2 + 1/2 = 3/2), and one and one sixth is the same as 7/6 (since 1 + 1/6 = 6/6 + 1/6 = 7/6). When we divide fractions, we multiply by the reciprocal of the divisor. So, (3/2) / (7/6) = (3/2) * (6/7) = 9/7, or 1 2/7 when expressed as a mixed number.
Next, to divide three fourths by one and three eights, we express these numbers as improper fractions as well. Three fourths is already an improper fraction, 3/4, and one and three eights is 11/8 (since 1 + 3/8 = 8/8 + 3/8 = 11/8). Dividing these gives us (3/4) \/ (11/8) = (3/4) * (8/11) = 24/44, which simplifies to 6/11.

The equation y = 5x represents the amount of miles Fran runs in x days. When a graph of this situation is drawn, what does the point (1, 5) on the graph represent? (asap if possible)
Answer:
The answer is "in one day, Fran runs 5 miles"
Step-by-step explanation:
In order to determine the answer, I have attached an image that shows the graph of the equation. We know that "x" represents days and "y" represents miles that Fran runs.
In any function, the pairs of coordinates are represented by (x,y) that belong to the function.
So in this case, the pair (1,5) represents:
x=1
y=5
It means, in one day Fran runs 5 miles.
