Answer:
[tex]\frac{h+p+32}{4}[/tex]
Step-by-step explanation:
distribute the parenthesis
h + p = 4k - 32 ( isolate 4k by adding 32 to both sides )
h + p + 32 = 4k ( divide both sides by 4 )
k = [tex]\frac{h+p+32}{4}[/tex]
expand the brackets, to get 4k-32
sp you have; h + p = 4k - 32
add 32 to both sides== h + p + 32 = 4k
/4
k= (h + p+ 32)/4
What is a positive number that equals 30 when added to it squared
Answer: 5
Step-by-step explanation:
Let x represent the number, then
x² + x = 30
x² + x - 30 = 0
(x + 6) (x - 5) = 0
x + 6 = 0 x - 5 = 0
x = -6 x = 5
↓
not valid since the restriction is that x > 0 (a positive number)
So, x = 5
A jogger is going running in a rectangular park that is 28 meters by 96 meters. Starting from where jogger's car is parked in the southeast corner, the jogger runs west along the width of the park and then north along the length. When the jogger reaches the northwest corner, she takes a shortcut straight back to her car. How far does the jogger run in all?
Final answer:
The jogger runs a total distance of 224 meters, which includes running along the width and length of the park and taking a shortcut diagonally across the park.
Explanation:
To calculate the total distance the jogger runs, we must add the distances from each leg of the jogger's path. Starting from the southeast corner, the jogger runs the width of the park (28 meters) to the west, and then the length of the park (96 meters) to the north, reaching the northwest corner. The shortcut from the northwest corner directly back to the southeast corner, where her car is parked, is the hypotenuse of the resulting right-angled triangle. To find the length of this hypotenuse, we use the Pythagorean theorem (a² + b² = c²), where the sides of the rectangle serve as 'a' and 'b'.
Let's calculate the hypotenuse:
a = 28 m (width)
b = 96 m (length)
c = √(a² + b²) = √(28² + 96²)
c = √(784 + 9216)
c = √10000
c = 100 m
Now, we sum up all the distances:
28 m (west along the width)
96 m (north along the length)
100 m (shortcut diagonally)
Total distance = 28 m + 96 m + 100 m = 224 meters

what is the value of x in the diagram below ?
Answer:
x = 9
Step-by-step explanation:
12^2 + a^2 = 54^2
a^2 = 54^2 - 12^2
a = sqrt (54^2 - 12^2) = 6 * sqrt(77)
Then calculate it for another triangle, where each side is 6 times shorter (as 12/2 = 6):
2^2 + (sqrt(77))^2 = x^2
x^2 = 81
x = 9
According to the real rational root theorem, what are all the potential rational roots of f(x)=5x3-7x+11
Answer:
x = -11, -11/5, -1, -1/5, 1/5, 1, 11/5,11
Step-by-step explanation:
The general formula for a third-degree polynomial is
f(x) = ax³ + bx² + cx + d
Your polynomial is
f(x) = 5x³ + 7x + 11
a = 5; d = 11
p/q = Factors of d/Factors of a
Factors of d = ±1, ±11
Factors of a = ±1, ±5
Potential roots are x = ±1/1, ±1/5, ±11/1, ±11/5
Putting them in order, we get the potential roots
x = -11, -11/5, -1, -1/5, 1/5, 1, 11/5, 11
(There are no rational roots. There is one irrational root and two imaginary roots.)

At first, the ratio of Dave's savings to Sam's savings was 5:4. After each of them donated $40 to charity, the ratio of Dave's savings to Sam's savings became 13:10. What was Dave's savings at first?
Let the initial savings at first be = x
Given ratio is [tex]\frac{5}{4}[/tex] and after donating $40 to charity, the ratio becomes [tex]\frac{13}{10}[/tex]
Hence, the relation becomes:
[tex]\frac{5x-40}{4x-40}=\frac{13}{10}[/tex]
[tex]10(5x-40)=13(4x-40)[/tex]
= [tex]50x-400=52x-520[/tex]
[tex]-2x=-120[/tex] or
[tex]2x=120[/tex]
[tex]x=60[/tex]
So , Dave's saving at first was 5x = 5*60 = $300
and Sam's saving at first was 4x = 4*60= $240

if sin (a+b)=k sin (a-b) prove that (k-1)cotb =( k+1) cota
Answer:
Proof
Step-by-step explanation:
Recall the identity [tex]\sin(a \pm b) = \sin(a)\cos(b) \pm \cos(a)\sin(b)[/tex].
Consider [tex]\sin(a + b) = k\sin(a - b)[/tex]. We firstly apply the above identity to reach
[tex]\sin(a)\cos(b) + \cos(a)\sin(b) = k(\sin(a)\cos(b) - \cos(a)\sin(b))[/tex].
By expanding the bracket on the right we obtain
[tex]\sin(a)\cos(b) + \cos(a)\sin(b) = k\sin(a)\cos(b) - k\cos(a)\sin(b)[/tex] and so
[tex]\cos(a)\sin(b) + k\cos(a)\sin(b) = k\sin(a)\cos(b) - \sin(a)\cos(b)[/tex] and so
[tex](1+k)\cos(a)\sin(b) = (k-1)\sin(a)\cos(b)[/tex] and so
[tex](k+1)\frac{\cos(a)}{\sin(a)}= (k-1)\frac{\cos(b)}{\sin(b)}[/tex] and finally
[tex](k+1)\cot(a)= (k-1)\cot(b)[/tex].
Final answer:
Using the sum and difference identities for sine, we can manipulate the equation sin(a+b) = k sin(a-b) to prove the trigonometric identity (k-1)cotb = (k+1)cota as required.
Explanation:
To solve the given trigonometric identity, we must show that if sin(a+b) = k sin(a-b), then (k-1)cotb = (k+1)cota. First, let's utilize the sum and difference identities for sine:
sin(a+b) = sin(a)cos(b) + cos(a)sin(b)
sin(a-b) = sin(a)cos(b) - cos(a)sin(b)
Substitute these into the original equation:
sin(a)cos(b) + cos(a)sin(b) = k(sin(a)cos(b) - cos(a)sin(b))
Now, distribute the k on the right side and arrange terms:
sin(a)cos(b)(1-k) = cos(a)sin(b)(1+k)
Divide both sides by sin(b)cos(b) to isolate cot(a) and cot(b):
(1-k) cot(b) = (1+k) cot(a)
This proves the identity as required. Notice that the cotangent function is the reciprocal of the tangent function, which is the ratio of sine to cosine.

Why is partitioning a directed line segment into a ratio of 1:3 not the same as finding the length of the directed line segment?
The ratio given is part to whole, but fractions compare part to part.
The ratio given is part to part. The total number of parts in the whole is 3 – 1 = 2.
The ratio given is part to part. The total number of parts in the whole is 1 + 3 = 4.
The ratio given is part to whole, but the associated fraction is .
Answer:
Third choice "The ratio given is part to part. The total number of parts in the whole is 1 + 3 = 4." is the correct answer.
Step-by-step explanation:
We know that partitioning a directed line segment into a ratio of 1:3 means that we are dividing the given line segment into two parts whose first part is 1 times the of some quantity while the another part is 3 times of the same quantity. So basically we are comparing part to part in by ratio. And total number of parts in the whole will be just sum of both so we get 1+3=4
Hence choice (3) is correct answer.
"The ratio given is part to part. The total number of parts in the whole is 1 + 3 = 4."
Answer:
it is C
The ratio given is part to part. The total number of parts in the whole is 1 + 3 = 4." is the correct answer.
Kyle has entered into a 5k marathon (5 kilometers). He wanted to figure out how many miles are in the marathon. If there are 1000 meters in 1 kilometer, and 1 mile equals approximately 1609.34 meters, how many miles will Kyle run in the marathon? Round your answer to the nearest hundredth place.
Answer:
3.10 miles
Step-by-step explanation:
1k = 0.62 miles
5x.62= 3.10
Kyle will run approximately 3.11 miles in a 5K marathon. This calculation is performed by first converting the 5K race distance into meters and then into miles, rounding the result to the nearest hundredth place.
Explanation:The subject of this question is conversions between different units of distance, specifically kilometers to miles. To help Kyle with this, first, we need to convert the kilometers into meters. Since 1 kilometer equals 1000 meters, therefore, 5 kilometers will be 5000 meters.
Then, remembering that 1 mile is approximately 1609.34 meters, we can divide the total meters by the conversion factor for meters to miles. Therefore, the conversion from meters to miles is as follows: 5000 meters / 1609.34 meters/mile = 3.11 miles.
So, if Kyle is running a 5K marathon, he will be running approximately 3.11 miles. This answer has been rounded to the nearest hundredth place as per your instructions.

Dan borrowed $750.00 from his brother with a 5% simple interest. If Dan pays his brother back in 6 months, how much does he have to pay back including the interest?
Answer:
$780
Step-by-step explanation:
The initial sum of money borrowed was $750
at a simple interest rate of 8%
Dan pays the money back in 6 months
The amount of money Dan has to pay back his brother including the interest in 6 months' time.
The total amount accrued, principal plus interest, from simple interest on a principal of $750 at a rate of 8% per year for 6 months is $780.
The total interest that is to be paid back can be calculated using the formula
where P is the prinicipal amount of money we begin with (in this case $750), r is the rate of interest (in this case 8%) and t is the time period (in this case, 6 months or 1/2 of a year).
(Note that we must take the value of t in years if the interest is annual interest and that is why we use t = 1/2 = 0.5 instead of t = 6).
So, by simple calculation we can find interest to be paid as
the interest accrued is $30
To find the total sum to be paid back, we add the initial sum or pricipal amount to the interest we have calculated above i.e.,
the total amount accrued, principal plus interest, from simple interest on a principal of $750 at a rate of 8% per year for 6 months is $780.

Joe's gas tank is 1/4 full. After he buys 6 gallons of gas, it is 5/8 full. How many gallons can Joe's tank hold?
Answer:
Amount of gas that can be hold by Joe's tank = 16 gallons.
Step-by-step explanation:
Given that Joe's gas tank is 1/4 full. After he buys 6 gallons of gas, it is 5/8 full. Now we need to find about how many gallons can Joe's tank hold.
So let's find change that happened after filling the gas.
Change = (5/8 full) - (1/4 full)
Change = (5/8 - 1/4) full
Change = (5/8 - 2/8) full
Change = (5 - 2)/8 full
Change = 3/8 full
So that means 3/8 full happens in 6 gallons
then 1 full will happen in 6/(3/8) gallons = 6*(8/3) gallons = 48/3 gallons = 16 gallons
So the amount of gas that can be hold by Joe's tank = 16 gallons.
