The radius of the cone is 5.13 cm.

Work out an estimate for the height of the cone.

Answers

Answer 1

Answer:

h=3.6cm

Step-by-step explanation:

v=1/3πr^2h

input your values

98=1/3×22/7×5.13×5.13×h

98=(22*5.13*5.13*h)/21

cross multiply

98*21=22*5.13*5.13*h

2058=22*5.13*5.13*h/22*5.13*5.13

3.6cm=h

perimeter of a rectangle is adding all the sides
it has two parallel and same sides
therefore multiply each side by 2 and add them
2(17.4x-0.8)+2(6x)
34.8x-1.6+12x
46.8x-1.6 is the perimeter

Answer:

Perimeter = 2(length) + 2(width)

Perimeter = 2(17.4x - 0.8) + 2(6X)

Perimeter = 34.8x - 1.6 + 12x

Perimeter = 46.8x - 1.6

A bag of oranges costs 6.40 dollars there are 16 oranges in each bag what would be the cost of 48

Answers

Answer:

Step-by-step explanation:

bag of oranges = $6.40

each bag = 16 oranges

48 divided by 16 = 3 (bags)

$6.40 x 3=  $19.20

The cost of 48 oranges would be $19.20 when the each cost 6.4

Given:

- Cost of a bag of oranges = $6.40

- Number of oranges in each bag = 16

First, let's find the cost per orange:

Cost per orange = Cost of a bag / Number of oranges in the bag

Cost per orange = $6.40 / 16 = $0.40

Now, the cost per orange is $0.40.

To find the cost of 48 oranges, multiply the cost per orange by the number of oranges:

Cost of 48 oranges = $0.40 * 48 = $19.20

Therefore, the cost of 48 oranges would be $19.20.

Dana saved 450 for food for her upcoming vacation. the breakfast was included with their hotel, but lunch and dinner are not. when dana cooks lunch or dinner it costs on average 10 . when the family goes to a restaurant for lunch or dinner it costs on average 40 . what is the maximum number of meals the family can eat at a restaurant.

Answers

The maximum number of meals the family can eat at the restaurant is 11

Amount saved by Dana for her upcoming vacation = 450

Average cost when Dana cooks lunch or dinner  = 10

Average cost when the family goes to a restaurant for lunch or dinner = 40

Maximum number of meals the family can have at the restaurant  = Amount saved by Dana/Average cost of a meal when the family goes to a restaurant

=450/40

= 11.25 or 11

So, the maximum number of meals the family can eat at the restaurant is 11 with a budget of 450.

A recipe had 4 tablespoons of seasoning to 6 cups of flour. So there is _____ of a tablespoon of seasoning for each cup of flour.

Answers

Answer:

Step-by-step explanation:

The ratio of seasoning to flour is 4:6.

This can also b re-written as a fraction. The fraction would be 4/6.

If you want to find the amount of seasoning per cup of flour, you must divide.

4/6  Divide the denominator (bottom number) by 6 to get a 1 on the bottom. Now divide the numerator (top number) be the same amount. This gives you a 0.66 on the top. Now you have 0.66/1.

0.66 is equivalent to 2/3, so for every 1 cup of flour, there is 2/3 a tablespoon of seasoning.

if the least common multiple of $a$ and $b$ is $1575$, and the ratio of $a$ to $b$ is $3:7$, then what is their greatest common divisor?

Answers

The greatest common divisor of two given numbers is 15.

Given that, the least common multiple of A and B is 1575 and A: B=3: 7.

We need to find what is their greatest common divisor.

What is the least common multiple?

The least common multiple is also known as LCM (or) the lowest common multiple in math. The least common multiple of two or more numbers is the smallest number among all common multiples of the given numbers.

We know that the product of the GCF and the LCM of two numbers is always the product of the two numbers.

Let the GCF of two numbers be x.

Then A×B=1575×x

Take A:B=3k:7k

Now, 3k×7k=1575×x

⇒21k²=1575x

⇒k²=75x

x must be expressed as a square divided by 75.

Now, 75=3×5×5

If we multiply 3 to the above product we get the perfect square number.

So, k²=225

⇒k=15

Now, 3k=45 and 7k=105

45=3×3×5 and 105=3×5×7

So, GCD=3×5=15

Therefore, the greatest common divisor of two given numbers is 15.

Your question is incomplete, probably the complete question/missing part is:

If the least common multiple of A and B is 1575, and the ratio A of B to 3 is 7 , then what is their greatest common divisor?

Answer: 75

Step-by-step explanation:

Since the ratio of A to B is 3:7:

There is an integer k for which A=3k and B=7k.

Moveover, k is the greatest common divisor of A and B, since 3 and 7 are relatively prime.

Recalling the identity lcm(A,B)*gcd(A,B)=AB, we find that 1575k=(3k)(7k), which implies k=1575/21=75.

arc xylocated on circle ahas a length of 40 centimeters. the radius of the circle is 10 centimeters. what is the measure of the corresponding central angle for xy⌢in radians?

Answers

We know that an arc is a part of the entire perimeter of a circle.

Radian is defined as a unit of plane angular measurement that is equal to the angle subtended by the circle at the center by an arc that is of the length equal to the radius

We also know that the circle as a whole contains 2π radians

Now first we are required to find the perimeter of the circle

Perimeter of the circle is given by the formula 2πr

Hence, perimeter of the circle = 2πr= 2π x 10 =20π=62.851cm

Hence value of arc in radians = 40/62.851 x 2π =0.636 x 2 π =1.272π

Radian can be converted to degree by multiplying the radian measure by 180/π

Therefore, angle subtended by arc in degrees =1.272 π x 180 /π =229.1 °

Hence the angle subtended by arc is 229.1°

Answers

The vertex of the parabola of the quadratic function that is increasing in the interval (-∞, 2), and decreasing in the interval (2, ∞), is the highest point on the parabola.

How can the type of vertex be found from the description of the quadratic function?

The given description of the quadratic function is presented as follows;

The interval the function is increasing = (-∞, 2)

The interval the function is decreasing = (2, ∞)

The graph of the function is therefore increasing from -∞ up to the point just before 2.

The graph of the function is decreasing from the point just after 2 to infinity.

The point 2 is therefore the highest point of the graph and also, the vertex of the quadratic function.

Justify Bob is a self-employed lawyer and is required to take a week of continuing legal education every year to maintain his license. This year he paid $1,295 in course fees for his continuing legal education in a different city. He also paid $467 for airfare and a hotel room and paid $250 for meals, all of which were provided by the hotels restaurant. Bob also purchased a $6 bag of snacks from a newsstand while waiting for his plane in the airport because he missed lunch.What is the total amount he can deduct on his Schedule C related to these expenses? Your goal in this section is to take a closer look at some aspects of the topic finding solutions ofquadratic equations. You are going to think deeper and test further your understanding about solvingquadratic equations using any of the four methods discussed.1. Sheryl says that the solutions of the quadratic equations w = 49 andw +49 = 0 are the same. Do you agree with Sheryl? Justify your answer.2. Patricia says that it's more appropriate to use the method of factoringthan extracting square roots in solving the quadratic equation4x - 9 = 0. Do you agree with Patricia? Explain your answer.3. If you are to choose between completing the square and factoring infinding the solutions of each of the following equations, which would youchoose? Explain and solve the equation using your preferred method.b. x + 7x + 12 = 0a. 4x - 20x = 114.
