5. A groundskeeper needs grass seed to cover a circular field, 320 feet in diameter. A store sells 60-pound bags of grass seed. One pound of grass seed covers about 600 square feet o field. What is the smallest number of bags the groundskeeper must buy to cover the circular field? Explain or show your reasoning,
Answer:
165
Step-by-step explanation:
First we need to find the area of the field, A = r^2 * pi
The radius is 290 / 2 = 145 feet
A = 145 * 145 * 3.14 = 66018.5 sqr feet
One bag covers 400 sqr feet
Divide the Area by 400 sqr feet to find number of bags needed.
66018.5 / 400 = 165
He will need at least 165 bags to cover the field

B. |x| ≤ 10.
What are inequalities and their types?Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
Given, An inequality is represented by the number line,
- 10, - 9, - 8, - 7, - 6, - 5, - 4, - 3, - 2, - 1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.
We know, |x| < a ⇒ x < a and x > - a.
Therefore, The inequality would be, |x| ≤ 10.
Q. Which inequality is represented by this number line?
- 10, - 9, - 8, - 7, - 6, - 5, - 4, - 3, - 2, - 1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.

You flip the y coordinate of point S from -4 to +4. The x coordinate stays the same.
=====================================================
Problem 5
Focus on the points W and X. Because the y coordinates are both 1, we subtract the x coordinates to get 4-1 = 3. The distance from W to X is 3 units. This is another way of saying segment WX is 3 units long. This applies to the preimage.
Then we're told the image has W'X' = 6 which is twice as long as WX = 3. Therefore, the scale factor is 2.
We can write it like this:
[tex]\text{scale factor} = \frac{\text{image length}}{\text{preimage length}} = \frac{W'X'}{WX} = \frac{6}{3} = 2[/tex]
This indicates that each side of W'X'Y'Z' is twice as long compared to each corresponding side of WXYZ.

Which set of rectangular coordinates describes the same location as the polar coordinates (4,pi)?
A. (0,-4)
B. (-4,0)
C. (0,4)
D. (4,0)
The rectangular coordinate of [tex]\mathbf{(4,\pi)}[/tex] is (-4,0)
The polar coordinate is given as:
[tex]\mathbf{(4,\pi)}[/tex]
To represent the polar coordinates properly, we make use of:
[tex]\mathbf{(r,\theta) = (4,\pi)}[/tex]
Where r represents radius
The rectangular coordinate is represented as: (x,y)
Where:
[tex]\mathbf{x = rcos(\theta)}[/tex]
[tex]\mathbf{y = rsin(\theta)}[/tex]
So, we have:
[tex]\mathbf{x = 4 \times cos(\pi)}[/tex]
Evaluate cos(pi)
[tex]\mathbf{x = 4 \times -1}[/tex]
Multiply
[tex]\mathbf{x = -4}[/tex]
Similarly,
[tex]\mathbf{y = 4 \times sin(\pi)}[/tex]
Evaluate sin(pi)
[tex]\mathbf{y = 4 \times 0}[/tex]
Multiply
[tex]\mathbf{y = 0}[/tex]
Recall that the rectangular coordinate is represented as (x,y)
Hence, the rectangular coordinate of [tex]\mathbf{(4,\pi)}[/tex] is (-4,0)

A hot-air balloon is 1200 feet off the ground and its altitude is slowly changing at a constant rate of −7 1/2 feet per second. How many seconds, s, will it take for the balloon to drop to below 310 feet? Drag and drop a symbol and value to correctly complete the solution to this inequality.
Using a linear function, it is found that it will take 118.7 seconds for the balloon to drop to below 310 feet.
What is a linear function?A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.In this problem:
A hot-air balloon is 1200 feet off the ground, hence [tex]b = 1200[/tex].Its altitude is slowly changing at a constant rate of −7 1/2 feet per second, hence [tex]m = -7\frac{1}{2} = -7.5[/tex]Then, the equation is:
[tex]y(t) = -7.5t + 1200[/tex]
It will drop below 310 feet when:
[tex]y(t) < 310[/tex]
Hence:
[tex]-7.5t + 1200 < 310[/tex]
[tex]-7.5t < -890[/tex]
[tex]7.5t > 890[/tex]
[tex]t > \frac{890}{7.5}[/tex]

The slope of the line is 7/3
The y-intercept is at y=-3
The graph represents the function 3y-7x + 9=0
What is slope of line ?
Slope of line is the angle made by the line from positive x-axis in anticlockwise direction, it also denoted the steepness of the line.
It is given that a coordinate plane with a straight line with a positive slope passing through the points, (0,-3) and (3, 4)
How using slope formula to find the slope m of line :
m = (y₂-y₁)/(x₂-x₁)
m = (4+3)/(3-0)
m = 7/3
Let us first find the equation of the line using point slope equation of line, Substituting all the values in above equation to get the equation of line :
(y-y₁) = m(x-x₁)
(y+3) = 7/3(x-0)
3y+9 = 7x
3y-7x + 9=0
Now, for y-intercept x= 0 that is :
3y-7x + 9=0
3y -0+9=0
3y = -9
y = -3
Therefore, the slope of the line is 7/3
The y-intercept is at y=-3
The graph represents the function 3y-7x + 9=0
