Randy drew a rectangle inside another with the size shown below on a piece of paper. He places the paper outside during a light rain. What is the approximate probability that a raindrop that lands on the paper will fall outside the shaded region?
Answer:
[tex]Probability = 84\%[/tex]
Step-by-step explanation:
First, calculate both areas
[tex]Area = Length * Width[/tex]
The area of the outer rectangle is:
[tex]Big\ Area = 20 * 25[/tex]
[tex]Big\ Area = 500cm^2[/tex]
The area of the small rectangle is:
[tex]Small\ Area = 10 * 8[/tex]
[tex]Small\ Area = 80cm^2[/tex]
The area outside the small rectangle is:
[tex]Outside = Big - Small[/tex]
[tex]Outside = 500cm^2 - 80cm^2[/tex]
[tex]Outside = 420cm^2[/tex]
So, the probability that it falls outside the paper inside is:
[tex]Probability = \frac{Outside}{Big\ Area}[/tex]
[tex]Probability = \frac{420cm^2}{500cm^2}[/tex]
[tex]Probability = \frac{420}{500}[/tex]
[tex]Probability = 0.84[/tex]
Express as percentage:
[tex]Probability = 0.84*100\%[/tex]
[tex]Probability = 84\%[/tex]

1. A square and a rectangle have the same area. The length of the rectangle is 32
centimeters, and the width of the rectangle is 2 centimeters. What is the length, in
centimeters, of a side of the square?
Answer:
8
Step-by-step explanation:
A=l*w
32*2=64
A=s*s
s=√A
√64
=8
The length in centimeters of the side of the square is 8 cm.
What is the area of a rectangle and a square?The area of a rectangle and a square are -
A{R} = Length x Breadth
A{S} = Side x Side
Given is that a square and a rectangle have the same area. The length of the rectangle is 32 cm and the width of the rectangle is 2 cm.
It is given that -
A{R} = A{S}
Length x Breadth = Side x Side
32 x 2 = (Side)²
(Side)² = 64
Side = 8
Therefore, the length in centimeters of the side of the square is 8 cm.

Identify a transformation of the function ƒ(x) = x^2 by observing the equation of the function g(x) = (x – 1)^2
Answer:
f(x) is translated 1 units left to give g(x)
Step-by-step explanation:
Given
[tex]f(x) = x^2[/tex]
[tex]g(x) = (x - 1)^2[/tex]
Required
How does f(x) transform to g(x)
[tex]f(x) = x^2[/tex]
When translated by b units left, it gives:
[tex]g(x) = f(x - b)[/tex]
In this case:
[tex]b = 1[/tex]
So:
[tex]g(x) = f(x - 1)[/tex]
If [tex]f(x) = x^2[/tex], then
[tex]f(x - 1) = (x - 1)^2[/tex]
Hence:
[tex]g(x) = (x - 1)^2[/tex]
This implies that; f(x) is translated 1 units left to give g(x)

Edith rides in an Oober that charges a flat rate of $6.75 plus $3.20 per mile. If the ride share service charges $40.03 in total for her trip, how many miles is her ride? Enter your NUMERICAL answer only in the box as a decimal to the nearest tenth of a mile.
Answer:
10.4 miles
Step-by-step explanation:
c(m) = trip cost
c(m) = 6.75 + 3.2m
40.03 = 6.75 = 3.2m
33.28 = 3.2m
m = 10.4

10+6 x=15+9 x-3 x
a one real solution
b the solution is 0
c no real solutions
d an infinite number of solutions
Answer:
c. no real solutions
Step-by-step explanation:
because:
1. 10+6x=15+9x-3x
6x+10=15+9x-3x
2. 6x+10=15+9x-3x
6x+10=15+6x
3. 6x+10=15+6x
6x+10=6x+15
4. 6x+10=6x+15
6x+10-10=6x+15-10
5. 6x=6x+5
6. 6x=6x+5
6x-6x=6x+5-6x
Then you get:
0=5
remember, If you want to know if an equation has no equation:
the constants are the numbers alone with no variables. If the coefficients are the same on both sides then the sides will not equal, therefore no solutions will occur. Use distributive property on the right side first.

Area of vertically tilted rectangles
1): area = 5 x 4 = 20 yd²
2): area = 5 x 4 = 20 yd²
Total area = 20 + 20 = 40 yd²
Area of horizontal rectangles:

2): area = 4 x 4 = 16 yd² [lower]
Area of given surface = 55.2 + 40 + 32 + 16 = 143.2 yd²

A particle P of weight 20 N is suspended by two strings AP and BP. The tension in string AP is (ai+8j)
and the tension in string BP is (6i+bj)
The value of a is?
And the value of b is?
The magnitude of the tension in string AP is?
The angle that string BP makes with the vertical is?
Give your answers as exact whole numbers or as decimals to 3 s.f.
Answer:
i. a = -6 ii. b = 12 iii. 100 iv. 26.6°
Step-by-step explanation:
Since the weight of the object is 20 N and directed downwards, its vector is -20j. Now, since the particle is in suspension, AP + BP = -20j
So, since AP = ai + 8j and BP = 6i + bj,
AP + BP = -20j
ai + 8j + 6i + bj = -20j
ai + 6i + 8j + bj = -20j
(a + 6)i + (8 + b)j = -20j
(a + 6)i + (8 + b)j = 0i - 20j
equating the components on both sids,
a + 6 = 0 and 8 + b = 20
a = -6 and b = 20 - 8 = 12
i. The value of a is -6
ii. The value of b is 12
iii. The magnitude of the tension in string AP is?
since AP = ai + 8j = -6i + 8j
magnitude of AP = √[-6² + 8²] = √[36 + 64] = √100 = 10
iv. The angle that string BP makes with the vertical is?
Since BP = 6i + bj = 6i + 12j, the angle it makes with the horizontal is Ф = tan⁻¹(12/6) = tan⁻¹(2) = 63.44°.
Thus, the angle it makes with the vertical is thus 90° - 63.44° = 26.56° (complementary angles) ≅ 26.6° to 3 s.f
1) The values of a and b of the given vectors are respectively; -6 and 12
2) The magnitude of the tension in string AP is; 10
3) The angle that string BP makes with the vertical is; 26.6°
What is the magnitude of the tension?
We are told that the weight of the particle P is 20 N. Since the particle is suspended by two strings, then its' direction is downwards and as such its vector is -20j.
By equilibrium;
AP + BP = -20j
1) We are given the tension vectors;
AP = ai + 8j and BP = 6i + bj,
Thus;
ai + 8j + 6i + bj = -20j
(ai + 6i) + (8j + bj) = -20j
(a + 6)i + (8 + b)j = -20j
(a + 6)i + (8 + b)j = 0i - 20j
Equating the components of both sides gives;
a + 6 = 0 and 8 + b = 20
Solving gives;
a = -6 and b = 20 - 8 = 12
Thus, the values of a and b are -6 and 12
2) The magnitude of the tension in string AP is gotten from resolution of the tension vector AP;
AP = ai + 8j = -6i + 8j
Thus, magnitude of AP = √(-6² + 8²) = √(36 + 64) = √100 = 10
3) The angle that string BP makes with the vertical is gotten from;
BP = 6i + bj = 6i + 12j
Thus, the angle it makes with the horizontal;
θ = tan⁻¹(12/6) = tan⁻¹(2) = 63.44°.
Angle it makes with the vertical = 90° - 63.44° = 26.56° ≈ 26.6°

The country of Sylvania has decided to reduce the number of its illiterate citizens by 3/5 each year. This year there are 9000 illiterate people in the country.
Write a function that gives the number of illiterate people in Sylvania, P(t), t years from today
Answer:
P(t)= 9000(0.4)^t
Step-by-step explanation:
Generally, we have an exponential function as follows;
P(t)= I(1 - r)^t
This case represents a decay ( decrease in value)
from what we have;
I represents the initial value, whereas r is the rate of change
From the question, we have that the change rate is the fraction 3/5
Writing this as a decimal, it is 0.6
substituting this back into the equation, we have;
P(t)= I(1-0.6)^t
P(t)= I(0.4)^t
I in this case is 9,000
So we have it that;
P(t) = 9000(0.4)^t

Answer:
[tex]\Huge\boxed{57.475 ft^2}[/tex]
Step-by-step explanation:
Hello there!
The following figure shown is a triangle
The area of a triangle can be calculated using this formula
[tex]A=\frac{bh}{2}[/tex] where b = base and h =height
The height of the triangle is 12.1 ft and the base length is 9.5ft
Knowing this information all we have to do is plug in the values into the formula
[tex]A=\frac{12.1*9.5}{2} \\12.1*9.5=114.95\\\frac{114.95}{2} =57.475\\A=57.475[/tex]
So we can conclude that the area of the triangle is 57.475 square feet
