outside the court ard is 120 m“, find the width of the path.
A square garden has an area of 441 m². If the path of uniform width surrounding inside the
garden is 216 m², find the width of the path.
Answer:
Area of a square garden = 2, 500 m².
Length of the side of the garden = √2,500 = 50 m.
Width of the path = 2.5 m.
Path is inside the garden.
Width of the garden that is inside (enclosed) by the path:
50 - 2 * 2.5 = 45 m.
Length of the garden inside by the path : = 45 m.
So the area of garden inside the path = 45 * 45 m²
= 2, 025 m².
Area of the path = 2, 500 - 2, 025
= 475 m².
Cost of laying the path = Rs 25 /m² * 475 m²
= Rs 11, 875.

The odds of winning a contest are approximately 5:1476. How many winners are there likely to be if there are 50000 participants?
Answer:
Approximately 169
Step-by-step explanation:
Set up as fractions and use cross multiplilcation to solve for the unknown.
These are our fractions from the information we are given; the winners represent the numerators (and x is the unknown, becuase we don't yet know how many winners there will be with 50000 participants). Note that the denominator on the first fraction is (1476 + 5) because we want it to represent TOTAL amount of particpants in the ratio:
[tex]\frac{5}{1481} = \frac{x}{50000}[/tex]
Now cross multiply by multiplying numerators and denominators that are ACROSS from each other, so 5 * 50000 and 1481 * x; now we have:
250000 = 1481x
Now to isolate x (to know its value) we need to divide both sides by 1481, and we are left with:
168.8 = x
But I rounded up to 169.

X - 6 = -24
Solve for x.
Answer:
x= -18
Step-by-step explanation:
x= -24 + 6
Add -24 and 6.
x= -18
Answer:
X = -18
Step-by-step explanation:
You want to isolate X by itself. To isolate X on one side of the = sign, use the addition property of equality (to undo the subtraction of 6 from x) by adding 6 to both sides of the equation. We use the addition property of equality because this is the inverse operation. It is important to add 6 to both sides of to maintain an equivalent equation.
1. Set up your equation
X - 6 = -24
+6 +6
2. Solve out
X - 6 = -24
+6 +6
X = -18

A line passes through the point (8,-4) and has a slope of 5/4
Answer:
y = 5/4x - 14
Step-by-step explanation:
Given:
Passes through (8, -4)
Slope (m) = 5/4
Slope-intercept equation:
y - y1 = m(x - x1)
y - (-4) = 5/4(x - 8)
y + 4 = 5/4x - 10
y = 5/4x - 14

Suppose that, as course instructor, you decide instead that you want to calculate a 95% confidence interval for the population proportion of all Cal Poly students who have ever marched in a Memorial Day Parade, and that you would like the margin of error of your 95% confidence interval to be .05, and that you would like to use a (most) conservative sample size for this task. What sample size should you use
Answer: 385
Step-by-step explanation:
If prior population proportion p is unknown, then the formula to compute sample size will be:
[tex]n= 0.25(\frac{z^*}{E})^2[/tex]
where, E= Margin of error, z* = Critical zvalue
Given: E= 0.05
Critical value for 95% confidence = 1.96
Required sample size: [tex]n=0.25(\frac{1.96}{0.05})^2[/tex]
[tex]\\=384.16\approx385[/tex]
Hence, the required sample size = 385

The foci of the hyperbola will be (3, -2 + √29) and (3, -2 - √29). Then the correct option is B.
What is a hyperbola?The hyperbola is the locus of a point such that the difference of distance from point P to two non-movable points. These two points are called foci of hyperbola.
The hyperbolic equation is given as,
(y - k)² /a² - (x - h)² /b² = 1
Then the foci of the hyperbola are given as,
(h, k + c) and (h, k - c)
The equation of the hyperbola is given below.
(y + 2)² /25 - (x - 3)² / 4 = 1
Compare the equations, then we have
(h, k) = (3, -2)
a² = 25
b² = 4
Then the value of 'c' is given as,
c² = a² + b²
c² = 25 + 4
c² = 29
c = √29
Then the foci of the hyperbola will be (3, -2 + √29) and (3, -2 - √29). Then the correct option is B.

Find the slope of a line passing through the given points.
(-4, 2) and (5,6)
slope =
Answer:
4/9
Step-by-step explanation:
To find slope without a graph, you subtract the 2 y-coords and the 2 x-coords, then divide the y-coord by the x-coord.
The formula is (y²-y¹)/(x²-x¹).
So we just plug in the coordinates.
(6-2)/(5-(-4))
(6-2)/(5+4)
4/9
So the slope is 4/9

A rectangular garden 800 square feet in area is to be fenced off against rodents. Find the dimensions that will require the least amount of fencing if one side of the garden is already protected by a barn.
Step-by-step explanation:
the area of a rectangle is
a × b
with a, b being the length and width (in any sequence).
a×b = 800
a = 800/b
the perimeter is
2a + 2b
one side is not needed, so we take one of them off. e.g. we take off one a.
a + 2b need to be a minimum
800/b + 2b
f(b) = 800/b + 2b
the extreme value(s) we find as the zero points of the first derivative.
f'(x) = -800/(b²) + 2 = 0
2 = 800/(b²)
2b² = 800
b² = 400
b = ±20 ft
negative lengths don't make sense, so, 20 ft is the solution.
a×b = 800
a×20 = 800
a = 40 ft
so, the minimum fencing is for
a = 40 ft
b = 20 ft (2 times)
the second a is covered by the barn.

(-2,-3) (-1,2) write the equation in y=mx+b
Answer:
y = 5x + 7
Step-by-step explanation:
(-2, -3) & (-1, 2)
First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(2 - (-3)) / (-1 - (-2))
Simplify the parentheses.
= (2 + 3) / (-1 + 2)
= (5) / (1)
Simplify the fraction.
5/1
= 5
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = 5x + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (-1, 2). Plug in the x and y values into the x and y of the standard equation.
2 = 5(-1) + b
To find b, multiply the slope and the input of x(-1)
2 = -5 + b
Now, add 5 to both sides to isolate b.
7 = b
Plug this into your standard equation.
y = 5x + 7
This is your equation.
Check this by plugging in the other point you have not checked yet (-2, -3).
y = 5x + 7
-3 = 5(-2) + 7
-3 = -10 + 7
-3 = -3
Your equation is correct.

Tom has a 490-page book to read. If he has already read 56 pages, how many more pages should he read each week
o finish in 6 weeks?
Write an equation for the situation and then answer the question.
If he has read 56 pages and there are a total of 490, then how many are left? That's 490 - 56 = 434.
To read 434 pages in 6 weeks, he should read 434 / 6 pages each week. That's 72 1/3 pages per week.
