Percentage change in perimeter is 100%.
Step-by-step explanation:
Step 1: Given length of rectangle 1, length = 5 ft and breadth = 3 ft.Calculate perimeter of R1 = 2 (length + breadth) = 2 (5 + 3) = 16 ft
Step 2: Given dimensions of 2nd rectangle is twice the first, length = 10 ft and breadth = 6 ft.Calculate perimeter of R2 = 2 (10 + 6) = 32 ft
Step 3: Calculate percentage change using the formula, (R2 - R1/R1) [tex]\times[/tex] 100= (32 - 16/16) [tex]\times[/tex] 100 = 100%

The given expression represents the area. Find the side length of the square.
The length of one side is _______.
Answer:
2x + 5
Step-by-step explanation:
Make sure you remember the area of a square with side which is [tex]s^{2}[/tex]. Once you figure that out, you need to find the length of a side, make sure you factor the expression of the area as a perfect-square trinomial.
An example of that is...
[tex]a^{2} +2ab+b^{2}[/tex] [tex]= (a +b)^{2}[/tex]
^^key point^^
Break it down and take the length out of the Square of Sum and you should get your answer.
Example: Use Square of Sum and get [tex](2x+5)^{2}[/tex] then, get rid of parentheses >> 2x + 5 and you should get your answer :)

Aiko had $20 dollars to buy candles returned 2 candles for which she had paid $4.75 each. Then she brought 3 candles for $3.50 each and I candle for $5.00. How much money Aiko have then?
Aiko has -$5.50 after buying the candles.
Explanation:To find out how much money Aiko has after buying candles, we need to calculate the total amount spent on the candles and subtract it from the initial $20.
Aiko initially had $20. She returned 2 candles for $4.75 each, so she got back 2 x $4.75 = $9.50.
Then, she bought 3 candles for $3.50 each, which amounts to 3 x $3.50 = $10.50.
Finally, she bought 1 candle for $5.00.
The total amount spent on candles is $4.75 x 2 + $3.50 x 3 + $5.00 = $9.50 + $10.50 + $5.00 = $25.50.
To calculate how much money Aiko has left, we subtract the total spent from the initial amount: $20 - $25.50 = $-5.50.
Therefore, Aiko owes $5.50 after buying the candles.
Which describes the location of vertex M after translation
Answer:
A
Step-by-step explanation:
A horizontal translation of - 3 means to subtract 3 from the original x- coordinate.
A vertical translation of - 3 means to subtract 3 from the original y- coordinate, thus
M(2, 2 ) → M'(2 - 3, 2 - 3 ) → M'(- 1, - 1 ) → A
Todd has 17 inches of rope. That’s 1/3 the length he needs. What is the total amount of rope needed
Answer:
51 inches of rope?
Step-by-step explanation:
If 17 inches is 1/3 if what he needs, then have 3 of 17 inches of rope which is
= 17 × 3= 51.. so it will be 3/3
Answer:
51 inches
Step-by-step explanation:
Total length of the rope possessed by Todd = 17 inches.
But what he has corresponds to [tex]\[\frac{1}{3}\][/tex] of his actual requirement.
Let his total requirement be represented by x.
Then [tex]\[\frac{1}{3} * x = 17\][/tex]
Simplifying,
[tex]\[x = 17 * 3\][/tex]
[tex]\[x = 51\][/tex]
Hence the total length of the rope required by Todd is 51 inches which is 3 times what he has currently.

are y=2x+6 and 6t=2x+9 perpendicular
Answer:
Therefore,
[tex]y=2x+6[/tex] and
[tex]6y=2x+9[/tex] are not Perpendicular.
Step-by-step explanation:
Given:
[tex]y=2x+6[/tex] ............................Equation of line( 1 )
[tex]6y=2x+9\\y=\dfrac{1}{3}+\dfrac{3}{2}[/tex] ............................Equation of line( 2 )
Solution:
So the Equations are written in
[tex]y=mx+b[/tex]
Where m is the slope of the line
On Comparing we get
[tex]Slope = m1 = 2[/tex]
[tex]Slope = m2 = \dfrac{1}{3}[/tex]
So for the lines to be Perpendicular.
Product of slopes = - 1
m1 × m2 = -1
So Product of slopes of the given lines are
[tex]m1\times m2=2\times \dfrac{1}{3}=\dfrac{2}{3}[/tex]
Which is not equal to -1
Therefore,
[tex]y=2x+6[/tex] and
[tex]6y=2x+9[/tex] are not Perpendicular.

How do you write 984 in scientific notation
Answer: 9.84 x 10²
Step-by-step explanation: To write 984 in scientific notation, first write a decimal point in the number so that there is only one digit to the left of the decimal point.
So here we have 9.84.
Next, count the number of places that we would need to move the decimal point in 9.84 in order to get back to the original number, 984.
Since we would need to move the decimal point two places to the right to get back to the original number, we have an exponent of 2.
Notice that our exponent is positive because we would need to move the decimal point to the right.
Now, scientific notation is always expressed as a power of 10. In this case, we have 10 to the 2nd or 10 to the 2nd power.
So 984 can be written in scientific notation as 9.84 x 10².

Together, teammates Pedro and Ricky got 2686 base hits last season. Pedro had 278 more hits than Ricky. How many hits did each player have?
Final answer:
Pedro had 1,482 hits, while Ricky had 1,204 hits. We determined these numbers by setting up a system of linear equations and solving for both players' hits using substitution.
Explanation:
To solve the problem of determining how many base hits teammates Pedro and Ricky had last season, we can set up a system of linear equations. Let's let P represent the number of hits Pedro had, and R represent the number of hits Ricky had. According to the problem, together they had 2,686 hits, so we can write the first equation as:
P + R = 2,686
The second piece of information tells us that Pedro had 278 more hits than Ricky, which gives us the second equation:
P = R + 278
We can substitute the second equation into the first equation to find the value of R:
P = (R + 278)
(R + 278) + R = 2,686
2R + 278 = 2,686
2R = 2,686 - 278
2R = 2,408
R = 1,204
Now, we know Ricky had 1,204 hits. To find out how many hits Pedro had, we substitute R's value back into the second equation:
P = 1,204 + 278
P = 1,482
So, Pedro had 1,482 hits and Ricky had 1,204 hits.

An oil barrel contains 31.6 gallons of oil. One gallon is equal to 3.8 L. How many liters of oil are in the barrel? Round your answer to the nearest tenth.
Final answer:
To convert gallons to liters, use the conversion factor of 1 gallon being equal to 3.8 liters to find that there are approximately 120.1 liters of oil in the barrel.
Explanation:
To convert gallons to liters, we need to use the conversion factor of 1 gallon being equal to 3.8 liters.
Calculate the total liters in the barrel: 31.6 gallons * 3.8 liters/gallon = 120.08 liters
Therefore, there are approximately 120.1 liters of oil in the barrel.

The sum of the interior angles of a triangle is equal to 180 degrees. Using this property, we can solve for the unknown angle in the triangle. In this case, the unknown angle is x. By setting up an equation and solving for x, we can determine that the value of x is B) 21.
The answer is B. 21.
The sum of the angles in a triangle is 180 degrees. So, we have the following equation:
(5x+14) + 40 + x = 180
Combining like terms, we get:
6x + 54 = 180
Subtracting 54 from both sides, we get:
6x = 126
Dividing both sides by 6, we get:
x = 21
Therefore, the value of x is 21.

360 + 36 = 396
Final answer:
To mentally calculate 9 x 44, use the distributive property by multiplying 9 by 40 and 9 by 4, then adding the results to get 396.
Explanation:
The question asks how to mentally calculate 9 x 44 using the distributive property. To do this, you can break down the multiplication into simpler parts. First, use the distributive property to express 44 as the sum of 40 and 4. Multiply 9 by each part:

What is an isosceles triangle?An isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case.
Given that, Jim owns a restaurant on the edge of a canyon. He wants to install a cable car over the canyon. He needs to know the width of the canyon. (please refer to the figure attached)
m ∠ ABC = 180°-80° (Linear pair)
m ∠ ABC = 100°
In Δ ABC,
∠ A + ∠ B + ∠ C = 180° (sum of interior angles of a triangle)
∠ A = 180°-(100°+40°)
∠ A = 40°
Since, ∠ A = 40° and ∠ C = 40°
Therefore, ∠ A = ∠ C
Therefore, AB = BC (Side opposite to equal angles are equal)
That means, Δ ABC is an isosceles triangle
∵ BC = 315 ft
∴ AB = 315 ft
AB is the width of the canyon.
Hence, The width of the canyon is 315 ft.
