[tex] \frac{new \: price - old \: price}{old \: price} \times 100 \: percent \\ = \frac{1.35 - 1.25}{1.25} \times 100 \: percent \\ = \frac{0.1}{1.25} \times 100 \: percent \\ = 8 \: percent[/tex]
Hope this helps..
Good luck on your assignment..
Answer:
B.8%
Step-by-step explanation:
First, you figure out that the price increased by ten cents by subtracting the old price from the new one.
Then you figure out what one percent of 1.25 is by dividing it by 100 to get 0.0125.
Finally you can plug in each answer and multiply it with 0.0125 so you end up with 10 cents or 0.1.
8 is the correct answer.
The perimeter of a rectangular pool is 312 m.
If the width of the pool is 68 m, what is its length?
Length of the pool:
m
The perimeter of a rectangle is calculated by:
[tex]\boxed{P=width +width+length+ length}[/tex]
Remember: In a rectangle, opposite sides are equals.
If we know how much is the width, then it's just apply it to the expression:
[tex]P=width+width+length+length\\312 =68 + 68 + length + length\\312 = 136+(2\cdot length)\\312 - 136 = 2\cdot length\\2\cdot length = 176\\length = \frac{176}{2} \\length = 88[/tex]
Therefore, the length of the pool is 88m.
A ball is thrown in air and it’s height, h(t) in feet, at any time, t in seconds, is represented by the equation h(t) =-t^2+7t. When is the ball higher than 10 feet off the ground?
Answer:
The ball is higher than 10 feet off the ground when the time is between 2 to 5 seconds
Step-by-step explanation:
In the above question, we are given the equation:
h(t) =-t²+7t.
We are asked to find the time (t) when the ball will be higher than 10 feet.
h(t) = height = 10 feet.
So we have:
10 = -t² + 7t
t² - 7t + 10 = 0
We have a quadratic equation hence we factorise.
t² - 5t - 2t + 10 = 0
(t² - 5t) +(2t - 10)= 0
t(t - 5) + 2 (t - 5) = 0
(t - 2) (t - 5) = 0
t - 2 = 0, t = 2
t - 5 = 0, t = 5
t = 5 and t = 2
Therefore, the ball is higher than 10 feet off the ground when the time is between 2 to 5 seconds.

Apply the distributive property to factor out the greatest common factor. 32 + 44 = 32+44=32, plus, 44, equals
Answer:
4 is the largest number that is common to both 32 and 44. Factoring it out looks like this: 4(8 + 11) = 4(8 + 11). That's weird to me but all textbooks begin that process just that same way.
Step-by-step explanation:
Greatest common factor of 32 and 44 is 4:
32/4 = 8
44/4 = 11
Factor 4 out of the equation 32 + 44 =
The factored form would be 4(8 + 11)

A number is divisible by 5 if the digit in the units or ones place is either 0 or 5. We want all digits to be even, so we throw out 5 as a candidate digit.
We're considering all numbers between 1000 and 9999, of which there are 9000. Numbers in this range can have any of the digits 0-9 in the tens and hundreds place, and any of 1-9 in the thousands place.
We also want all digits to be even, which means we can pull from the numbers {0, 2, 4, 6, 8} in the hundreds and tens places, and {2, 4, 6, 8} in the thousands place.
So there are 4*5*5*1 = 100 numbers in this range that are divisible by 5.

A carpenter uses a hand saw to cut a piece of wood in half. The length of the saw blade is 40 cm, while the wood he is cutting is 8 cm across. Each time he extends the saw out with his arm, there is 5 cm of blade between the handle and the wood. When he pulls the saw toward his self with his arm, the saw handle is 25 centimetres from the wood. Each time he extends his arm out and pulls it back in, 1 second has passed. He starts with his arm extended out. Write an equation that models how far the tip of the saw is from the wood in terms of time.
Answer:
The equation that models how far from the tip of the saw is from the wood in terms of time is x(t) = 10×cos(2×π×t) + 17
Step-by-step explanation:
The given parameters are;
Length of the saw blade = 40 cm
Thickness of the wood across = 8 cm
Length of blade between wood saw handle with hand extended = 5 cm
Length of the tip from the wood at the above time = 40 - 8 - 5 = 27 cm
Length of blade between wood saw handle with saw pulled inwards = 25 cm
Length of the tip from the wood at the above time = 40 - 8 - 25 = 7 cm
Time for one complete cycle = 1 second
We note that the basic equation for oscillatory motion is of the form;
x(t) = A·cos(ωt) + d
Where:
A = Amplitude of the motion = (27 - 7)/2 = 10 cm
ω = Angular frequency = 2·π/T
ωt = Motion's phase
t = Time of the motion
d = The middle location = 27 - 10 = 17 cm
T = The time to complete a cycle = 1 s
Therefore;
ω = 2·π
Given that he stars with his arm extended out, we have;
27 = 10×cos(2×π×0) + 17
Therefore, the equation that models how far from the tip of the saw is from the wood in terms of time is x(t) = 10×cos(2×π×t) + 17.

7( r - 2 ) - 9(r - 1) = 3 ( 5 - r ) + ( r - 8 )
Distribute 7 through the parentheses
7r - 14 - 9(r - 1 ) = 3( 5 - r ) + ( r - 8)
Distribute -9 though the parantheses
7r - 14 - 9r + 9 = 3(5 - r ) + ( r - 8)
Distribute 3 through the parantheses
7r - 14 - 9r + 9 = 15 - 3r + r - 8
When there is (+) in front of an expression in parentheses, the expression remains the same
7r - 14 - 9r + 9 = 15 - 3r + r - 8
Collect like terms
7r - 9r - 14 + 9 = 15 - 3r + r - 8
-2r - 14 + 9 = 15 - 3r + r - 8
Calculate
-2r- 5 = 15 - 3r + r - 8
Subtract the number
-2r - 5 = 7 - 3r + r
Collect like terms
-2r - 5 = 7 - 2r
Cancel equal terms on both sides of the equation
- 5 = 7
The statement is False for any value of X.
Hence, there is no solution.

Step-by-step explanation:
In arithmetic progression common difference is given by
d = nth term - (n-1)th term.
In geometric progression common ratio is given by
r = nth term / (n-1)th term.
Another thing important to note is that in both AP and GP common difference and common ratio remains same for any two consecutive terms which can be calculated using above formula.
we will be using this concept to solve this problem.
________________________________
Let look at the problem
series
11, 6 ,1
Lets try to find common difference for this series
common difference of third and second term = 1-6 = -5
common difference of second term and first term = 6 -11 = -5
Thus, we see that common difference is same in both case ,
hence it can be concluded that series is Arithmetic progression.
another way to validate this is
nth term of AP is given by
nth term = a + (n-1)d
where a is first term
lets try to find third term using this formula and using d = -5 and a = 11
3rd term = 11 + (3-1)-5 = 11 + 2*-5 = 11- 10 = 1
Thus, we see that third term calculated is same as given in series i.e 1
Hence series is Arithmetic progression validated as well.
______________________________________________
Problem is solved but lets see if the series is GP or not
common ratio of third and second term = 1/6 = 1/6
common ratio of second term and first term = 6 /11
Thus, we see common ratio is not same for the two consecutive term in the series and hence series cannot be geometric progression.

How many ways are there to split 14 people into seven pairs?
There are 9,232,320 ways to split 14 people into seven pairs.
To split 14 people into seven pairs, we need to find the number of ways to arrange the people into those pairs.
Let's break down the process step by step:
1. Selecting the first pair: We have 14 people to choose from for the first person in the first pair. After selecting the first person, we have 13 people remaining to choose from for the second person in the pair. Since the order of selection doesn't matter, we divide by 2 to account for the fact that we have counted each pair twice (e.g., choosing A then B is the same as choosing B then A).
Therefore, the number of ways to select the first pair is (14 * 13) / 2 = 91.
2. Selecting the second pair: We have 12 people remaining after forming the first pair. Similar to the first pair, we have 12 choices for the first person and 11 choices for the second person in the second pair. Again, we divide by 2 to account for the order of selection.
The number of ways to select the second pair is (12 * 11) / 2 = 66.
3. Continuing this process, we select pairs until all 14 people are paired up. Each time, the number of remaining people decreases by 2.
So, the total number of ways to split 14 people into seven pairs is:
91 * 66 * 40 * 24 * 10 * 6 * 2 = 9,232,320.
Therefore, there are 9,232,320 ways to split 14 people into seven pairs.
