Wesley has three different rectangular stickers. The red sticker is V2 cm
long and 1.5 cm wide. The green sticker is v12 cm long and 0.5 cm wide.
The yellow sticker is 3 cm long and 1.25 cm wide. Order the side lengths of
the stickers from greatest to least. Which sticker has the greatest area?
The order of the rectangular area from greatest to least is green sticker > yellow sticker > red sticker
What is the area of a rectangleThe area of a rectangle is calculated by multiplying its length by its width. So if the length of a rectangle is l and the width is w, then its area A is given by the formula A = l x w.
To solve this problem, we can find the area of each sticker one after the other.
Area = length * width
1. red sticker = 2 * 1.5 = 3cm²
2. green sticker = 12 * 0.5 = 6cm²
3. yellow sticker = 3 * 1.25 = 3.75cm²
The order is green sticker > yellow sticker > red sticker

The equation of line is y = ( -1/2 )x + 7/2 , where the slope is m = -1/2
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let the first point be P ( -1 , 4 )
Let the second point be Q ( -5 , 6 )
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 6 - 4 ) / ( -5 - ( - 1 ) )
Slope m = 2 / ( -5 + 1 )

A disc is rolled thrice what is the probability
Probability of an event = (number of favorable event) / (total number of event).
P(B) = (Event B) / (total number of event).
Probability of getting 1 = 1/6.
Rolling dice is an independent event, it is not dependent on how many times it’s been rolled.
Probability of getting 1 three times in a row = probability of getting 1 first time × probability of getting 1 second time × probability of getting 1 third time.
Probability of getting 1 three times in a row = (1/6) × (1/6) × (1/6) = 1/216.
Hence, the probability of getting 1 three times in a row is 0.463%.

What is the driving time for a 1800-mile trip if you drive at an average speed of 45 miles per hour? What is the driving time at 69 miles per hour?
Answer:
40 hours
26.09 hours
Step-by-step explanation:
What is the driving time for a 1800-mile trip if you drive at an average speed of 45 miles per hour?
1800 / 45 = 40 hours
What is the driving time at 69 miles per hour?
1800 / 69 = 26.09 hours
Step-by-step explanation:
The driving time for a 1800-mile trip at an average speed of 45 miles per hour can be calculated as
Driving time = Total distance / Average speed
Driving time = 1800 miles / 45 miles per hour = 40 hours
Similarly, the driving time at an average speed of 69 miles per hour can be calculated as:
Driving time = 1800 miles / 69 miles per hour = 26 hours
So if you drive at an average speed of 45 miles per hour, the driving time for a 1800-mile trip would be 40 hours, and if you drive at an average speed of 69 miles per hour, the driving time would be 26 hours.

The sample variance and standard deviation are given as follows:
Variance = 87.22 %.
Standard deviation = 9.34%.
To obtain the variance and the standard deviation first, we must obtain the mean, which is given by the sum of all observations divided by the number of observations, hence:
Mean = (77.1 + 82.9 + 90 + 91.3 + 81.9 + 83.3 + 84.9 + 82.5 + 84.6)/10
Mean = 75.85.
Then we must obtain the sum of the differences squared between each observation and the mean, as follows:
(77.1 - 75.85)² + (82.9 - 75.85)² + (90 - 75.85)² + (91.3 - 75.85)² + (81.9 - 75.85)² + (83.3 - 75.85)² + (84.9 - 75.85)² + (82.5 - 75.85)² + (84.6 - 75.85)² = 784.9825
The sample variance is given by the above sum divided by one less than the sample size, hence:
Variance = 784.9825/9
Variance = 87.22 %.
The standard deviation is the square root of the variance, hence:
Standard deviation = sqrt(87.22)
Standard deviation = 9.34%.

Answer:
First side: 40in
Second side: 20in
Third side: 36in
Step-by-step explanation:
Let's call the triangle's first, second, and third sides a, b, and c respectively.
The perimeter of the triangle is 96in: a+b+c=96
The length of the first side is twice the second: a=2b
The third side is 16in more than the second: c=b+16
Now, consider the equation a+b+c=96 again, but sub '2b' in for a, and 'b+16' for c, in order to find the value of b:
a+b+c=96
2b+b+b+16=96
4b=80
b=20
Use this value for b to find a and c:
a=2b=2(20)=40
c=b+16=20+16=36
Answer:
Step-by-step explanation:
Let's call the length of the second side "x". Then, the length of the first side is 2x and the length of the third side is x + 16.
The perimeter of the triangle is the sum of the lengths of its sides, so we can set up an equation to solve for x:
x + 2x + (x + 16) = 96
Expanding the equation and solving for x, we get:
4x + 16 = 96
4x = 80
x = 20
So, the length of the second side is 20 inches, the length of the first side is 2 * 20 = 40 inches, and the length of the third side is 20 + 16 = 36 inches.

A man is considering two companies from which to rent a truck. Triangle Truck Rental charges $35 per day and 50 cents a mile. Circle Rent-A-Truck charges $55 a day
and 30 cents a mile. How far would he need to drive in one day for the both companies to have the same total cost?
How many miles would he need to drive in the day?
____ miles
Answer:
10 miles
Step-by-step explanation:
Let's call the number of miles driven in a day "x". The total cost for Triangle Truck Rental can be expressed as:
Cost (Triangle) = $35 + 0.5x
The total cost for Circle Rent-A-Truck can be expressed as:
Cost (Circle) = $55 + 0.3x
We want to find the value of x such that Cost (Triangle) = Cost (Circle). So we can set the two expressions equal to each other and solve for x:
$35 + 0.5x = $55 + 0.3x
0.2x = $20
x = 100 miles
So the man would need to drive 100 miles in one day for both companies to have the same total cost.
Decide which of the two given prices is better and explain why. Storage locker A rents for $33/yd^2 per month. Storage locker B rents for $1.49/ft^2 per week. (Assume 1 month=4 weeks.)
B is significantly more affordable and better than A, renting for $1.62 per square foot.
Yard and feet conversion:Yard and feet are used to estimate the length. Both of the units are used in the royal and US customary system of measurements. The value of one yard is equal to three feet.
To compute Square yard to Square Feet, where Square yard is equal to 9 Square Feet, multiply the value in Square yard by 9. one can also use the Square yard to Square Feet calculator.
1 yard² = 9 feet²
A rents for $33 per yard squared
hence A rents $33 for 9 feet squared
hence A rents $3.67 per feet squared( $33/9) which is costlier than $1.49 per feet squared
Thus, as B is more economical, it is better.

Jonathan drove his motorcycle on the highway at 160 miles per hour. His speed increased every three seconds as the roads got wider. What is the rate of change?
We can presume that x is a positive number because we are aware of the widening of the roadways and the increase in Jonathan's speed. It takes three seconds for Jonathan's speed to change by 234.67 + 2x feet per second.
In plain English, what is speed?the definition of speed. a direction or speed at which an object's location changes. The distance travelled relative to the time it took to travel that distance is how fast something is moving.
What does science mean when it refers to speed?In contrast to velocity, which describes the speed and direction of an object's movement, speed is the rate of movement along a path. Alternatively, velocity is a vector while speed is a scalar quantity.
Let's first convert Jonathan's initial speed of 160 miles per hour to feet per second, since we're measuring the change in speed every three seconds.
160 miles per hour = 160 * 5280 feet per hour = 844800 ft/h
= 844800/3600 ft/s (since there are 3600 seconds in an hour)
= 234.67 ft/s (rounded to two decimal places)
Now, let's assume that Jonathan's speed increases by x feet per second every three seconds. After three seconds, his new speed will be 234.67 + x feet per second. After another three seconds, his speed will be 234.67 + 2x feet per second, and so on.
Since we know that the roads are getting wider and Jonathan's speed is increasing, we can assume that x is a positive number.
Therefore, the rate of change of Jonathan's speed is 234.67 + 2x feet per second every three seconds.
