the perimeter of a isosceles triangle is 47 cm. what is the length of each of its legs? a. 15 cm b. 17.5 cm c. 19.5 cm d. 35 cm
The length of the third side of an isosceles triangle is 9 cm.
Define isosceles triangle.
A triangle with two sides that are congruent or that are the same length is known as an isosceles triangle.
Define perimeter.
The sum of the lengths of the three sides of an isosceles triangle can be used to determine its perimeter. Two of the sides of an isosceles triangle are equal in length. Therefore, if we know the base length and the other two equal side lengths, we can determine the perimeter.
Given data -
Perimeter of an isosceles triangle = 47cm
The sum of the equal sides = 38 cm
Let a be the length of equal sides.
Therefore 2a = 38
Perimeter of an isosceles triangle = 2a + b
47 = 38 + b
b = 47 - 38
b = 9 cm
The length of the third side of an isosceles triangle is 9 cm.

There is a 25ft fence, 130 feet away from where the ball was hit. If the ball was hit towards the fence would it be high enough to clear
If the maximum height of the ball is greater than or equal to the height of the fence, then it would clear the fence.
To determine whether the ball hit towards the fence would clear it, we need to use the laws of projectile motion. Assuming the ball was hit at an angle of 45 degrees, we can calculate the maximum height it would reach using the following formula:
h = (\(v^{2}\) * \(sin^{2} \alpha\)) / (2g)
where h is the maximum height, v is the initial velocity, \(\alpha\) is the launch angle, and g is the acceleration due to gravity (9.8 m/\(s^{2}\)).
Since we know the distance the ball traveled (130 feet), we can use the following formula to calculate the initial velocity:
d = \(v^{2}\) * sin(2\(\alpha\)) / g
where d is the distance, v is the initial velocity, \(\alpha\) is the launch angle, and g is the acceleration due to gravity (9.8 m/\(s^{2}\)).
Converting the distance and height to meters (since the formula uses SI units), we have:
d = 130 * 0.3048 = 39.624 m
h = 7.62 m (assuming a 45 degree launch angle)
Using the second formula, we can solve for the initial velocity:
v = \(\sqrt{dg/sin2\alpha }\) = \(\sqrt{39.624*9.8/sin(90)}\) = 28.07 m/s
To determine whether the ball would clear the fence, we need to calculate the height of the fence in meters:
fence_height = 25 * 0.3048 = 7.62 m
If the maximum height of the ball is greater than or equal to the height of the fence, then it would clear the fence. In this case, since the maximum height is 7.62 m and the fence height is also 7.62 m, the ball would just clear the fence if it was hit directly towards it at a launch angle of 45 degrees. However, if the ball was hit at a different angle or with a different initial velocity, the outcome could be different.

There is a 25ft fence, 130 feet away from where the ball was hit. If the ball was hit towards the fence, would it be high enough to clear the fence?

Given a right triangle with sides a = 3 , b = 4, and c = 5. Find the missing side c of another right triangle with a = 6 and b = 8 ? Explain your answer.Plz u will lots of point
c = 10
Step-by-step explanation:
We can find out the missing side of a right triangle by using the Pythagorean theorem.
The Pythagorean theorem is...
\(a^2+b^2=c^2\)
We can even double check the first problem by plugging in everything into the theorem and solving, everything will come out correct. We can plug in the numbers from the second problem into the theorem and find c, also please note that the hypotenuse of a triangle will always be c. It doesn't matter which you put in for a or b, but since the problem gives us which one is a and which one is b, I'll just be plugging it in like that.
\(6^2+8^2=c^2\)
\(36+64=c^2\)
\(100=c^2\)
A lot of people will stop here and think that the answer is 100, but you need to find the square root of 100, since c is squared. The square root of 100 is 10, so...

C. 207.70 miles
D. 249.22 miles
Please help!! :00
Answer:
The answer is B. 283.8 miles.\(\sqrt{b^2\)
Step-by-step explanation:
Using the cosine rule:
b^2 = a^2 + p^2 - 2ap(cosB)
b^2 = 172.20^2 + 111.64^2 - 2 x 172.20 x 111.64(cos177.29)
b^2 = 42,116.33 - 38,448.82(cos177.29)
b^2 = 42,116.33 - (-38,405.82)
b^2 = 42,116.33 +38,405.82
b^2 = 80,522.15

Show your work or explain how you found your answer
Part A: The correct statement based on the recipe is "1/2 cup of milk is used to make each muffin."
The recipe states that 1/2 cup of milk is used to make each muffin. None of the other statements (12 cups of milk, a cup of milk, a cup of milk, a cup of milk, cup of milk) align with the information provided in the recipe.
Part B: To determine how many batches of 12 muffins can be made using one gallon of milk, we need to convert the units appropriately.
Given:
1 gallon = 128 fluid ounces
1 cup = 8 fluid ounces
To find out how many cups are in a gallon, we divide 128 by 8:
128/8 = 16 cups
Since each batch requires 1/2 cup of milk, we divide the total cups in a gallon by 1/2:
16 / (1/2) = 16 * 2 = 32
Hence, using one gallon of milk, it is possible to make 32 batches of 12 muffins.

4-21. Kelso's mom wants to put a floating blanket over the family's circular wading pool to keep the heat in and the leaves out. The pool has a diameter of 10 feet. a. How many square feet of blanket will Kelso's mother need? b. If the pool supply store charges $0.10 per square foot for the blanket, how much will the material for the blanket cost?
Answer:
a. 78.6 square feet
b. $7.86
Step-by-step explanation:
a. This simply asks us to calculate the area of the 10 feet diameter pool
Formula for area of circle is ;
pi * r^2 = pi * d^2/4
so Area = 22/7 * 10^2/4 = 78.60 square feet
b. This will be the area of the blanket multiplied by the price per square foot of the blanket
Mathematically, we have that as;
78.60 * 0.1 = $7.86

Find the first term and the common difference of the arithmetic sequence whose 9th term is 20 and 20th term is 53.
First term is:__________
Common difference is:_________
In the given arithmetic sequence, the 9th term is 20 and the 20th term is 53. The first term of the sequence is -17, and the common difference is 3.
To find the first term and the common difference of an arithmetic sequence, we can use the formula for the nth term of an arithmetic sequence:
an = a1 + (n-1)d,
where an represents the nth term, a1 is the first term, n is the position of the term in the sequence, and d is the common difference.
Given that the 9th term is 20, we can substitute n = 9 and an = 20 into the formula:
20 = a1 + (9-1)d
20 = a1 + 8d.
Similarly, using the 20th term being 53, we have:
53 = a1 + (20-1)d
53 = a1 + 19d.
We now have a system of equations:
a1 + 8d = 20,
a1 + 19d = 53.
By solving this system of equations, we can find the values of a1 and d. Subtracting the first equation from the second equation, we have:
(19d - 8d) = 53 - 20,
11d = 33,
d = 3.
Substituting the value of d into one of the original equations, we find:
a1 + 8(3) = 20,
a1 + 24 = 20,
a1 = 20 - 24,
a1 = -4.
Therefore, the first term of the arithmetic sequence is -4, and the common difference is 3.

Suppose you borrowed $45,000 at a rate of 8.5% and must repay it in 5 equal installments at the end of each of the next 5 years. By how much would you reduce the amount you owe in the first year? Select the correct answer. a. $7,594.46 b. $7,600.46 c. $7,618.46 d. $7,612.46 e. $7,606.46
The correct answer is option a. $7,594.46.
To calculate the amount you would reduce the amount you owe in the first year, we can use the formula for the equal installment of a loan. The formula is:
Installment = Principal / Number of Installments + (Principal - Total Repaid) * Interest Rate
In this case, the principal is $45,000, the number of installments is 5, and the interest rate is 8.5%.
Let's calculate the amount you would reduce the amount you owe in the first year:
Installment = $45,000 / 5 + ($45,000 - $0) * 0.085Installment = $9,000 + $3,825
Installment = $12,825
Therefore, you would reduce the amount you owe by $12,825 in the first year.The correct answer is option a. $7,594.46.

Which equation matches the graph of the greatest integer function given
below?
Answer:
B. y = [x] + 3
Step-by-step explanation:
The answer to this graph would be
B. y = [x] + 3
This is because the graph is translated up by 3 units. Such that a value of 0 passed into x would give us a y value of 3 on the graph, which is represented as a black dot. For a value of -4 passed as x, the largest integer that is less than -4 would be -4 itself and if we add 3 to it due to following this function, we get a y value of -1 which is what is represented in the graph.
The following cone has a slant height of 17
cm and a radius of 8
cm.
What is the volume of the cone?
Responses
480π
320π
544π
The formula for the volume of a cone is:
V = (1/3)πr²h
where r is the radius of the base, h is the height of the cone, and π is pi.
In this case, the slant height is given as 17 cm, which we can use with the radius to find the height of the cone using the Pythagorean theorem:
h² = s² - r²
h² = 17² - 8²
h² = 225
h = 15
Now that we have the height, we can plug in the values for r and h into the formula for the volume:
V = (1/3)π(8²)(15)
V = (1/3)π(64)(15)
V = (1/3)(960π)
V = 320π
Therefore, the volume of the cone is 320π cubic cm. Answer: 320π.
