Frank has a circular garden. The area of the garden is 100 ft2. What is the approximate distance from the edge of Frank’s garden to the center of the garden? (A = πr2)
Answers
The distance from the edge of Frank's garden to the center of the garden is about 2.815 feet.
To find the approximate distance from the edge of Frank's garden to the center, we first need to determine the radius of the circular garden. We are given the area (A) of the garden, which is 100 square feet. The formula for the area of a circle is A = πr², where A is the area and r is the radius.
We can rearrange the formula to solve for the radius:
r² = A / π
Now, plug in the given area:
r² = 100 ft² / π
Calculate the square of π (approximately 3.1416):
r² = 100 / 3.1416
r² = 31.8309
Now, find the square root of r² to get the radius:
r ≈ √31.8309
r = 5.63 ft
Now that we have the radius, we can find the distance from the edge to the center. In a circle, the distance from the edge to the center is half the radius. So, we can calculate this as follows:
Distance from edge to center ≈ (1/2) * radius
Distance from edge to center ≈ (1/2) * 5.63 ft
Distance from edge to center ≈ 2.815 ft
A water cup is in the shape of the cone. The diameter of the cup is 3 inches and the height is 6 inches.

Use 3.14 for pi.
Enter your answer, as a decimal, in the box.
____ in3
Answers
Answer:
volume of water cup could hold is, 14.13 square inches.
Step-by-step explanation:
Volume of a cone(V) is given by:
[tex]V = \frac{1}{3} \pi r^2 h[/tex] .....[1]
where,
r is the radius of the cone
h is the height of the cone
As per the statement:
A water cup is in the shape of the cone. The diameter of the cup is 3 inches and the height is 6 inches.
⇒height(h) = 6 inches and diameter(d) = 3 inches
We know that:
diameter(d) =2 (radius)
[tex]3 = 2r[/tex]
Divide both sides by 2 we get;
[tex]r = 1.5[/tex]
substitute these in [1] we have;
Use [tex]\pi = 3.14[/tex]
[tex]V = \frac{1}{3} \cdot 3.14 \cdot 1.5^2\cdot 6[/tex]
⇒[tex]V = \frac{1}{3} \cdot 3.14 \cdot 13.5[/tex]
Simplify:
[tex]V = 14.13 in^3[/tex]
Therefore, the volume of water the cup could hold is, 14.13 square inches.
Final answer:
The volume of water a cone-shaped cup can hold, with a diameter of 3 inches and height of 6 inches, using the formula for the volume of a cone, is 14.13 cubic inches.
Explanation:
The question asks us to calculate the volume of water a cone-shaped cup can hold given its dimensions. The diameter of the cup is 3 inches, and its height is 6 inches. To find the volume of a cone, we use the formula V = 1/3 πr²h, where V is the volume, r is the radius, h is the height, and π (pi) is approximately 3.14.
First, we find the radius of the cup. The diameter is 3 inches, so the radius (half the diameter) is 1.5 inches. Substituting the radius and the height into the formula, we get:
V =1/3 × 3.14 × (1.5²) × 6 = 1/3 × 3.14 × 2.25 × 6 = 1/3 × 3.14 × 13.5 = 14.13 cubic inches
Therefore, the volume of water the cup could hold is 14.13 cubic inches.

Kelly ran 2 miles and burned 240 calories. The next day she ran 3 miles and burned 360 calories. The next day 4 miles and 480 calories. If this pattern continues, how many calories will she burn if she runs 8 miles?
Answers
Hope this helps :)
So we know there's a pattern, and that it is increasing. But what is it increasing by?
Well, take a look:
240 + 120 = 360
360 + 120 = 480
This means that the pattern is increasing by 120 each mile. Simply continue adding 120 to each mile. (Or, Multiply 120 by 8)
5 miles = 600 calories
6 miles = 720 calories
7 miles = 840 calories
8 miles = 960 calories
Answer:
Kelly will burn 960 calories if she runs 8 miles.
Omar has $32 to spend at the store. He bought one bag of apples which cost $4 each, 3 mangoes which cost $2 each, one block of cheese which costs $5, and a pizza which costs $15. How much change will Omar receive after his purchase?
Brainliest
Answers
For this case the total change is given by the following relationship:
Total change = Amount of money - Total costs.
Amount of money = $ 32
The total costs are given by the sum of each purchase.
We have then:
Total costs = 4 + (3 * 2) + 5 + 15
Total costs = 4 + 6 + 5 + 15
Total costs = $ 30
Substituting values we have:
Total change = 32 - 30
Total change = 2 $
Answer:
Omar will receive after his purchase about:
Total change = 2 $
Answer:
2
Step-by-step explanation:
Total costs = 4 + (3 * 2) + 5 + 15
Total costs = 4 + 6 + 5 + 15
Total costs = $ 30
Substituting values we have:
Total change = 32 - 30
Total change = 2 $

Abigail is using her mothers pancake recipe but she wants to make 60% more pancakes than the recipe usually prepares.If her mother’s recipe calls for 1/2 cup of flour,how much flour will Abigall need to use?
Answers
Final answer:
Abigail will need to use 0.8 cup of flour to make 60% more pancakes than the original recipe.
Explanation:
To determine how much flour Abigail needs to use, we can set up a proportion based on the increase in the number of pancakes. If her mother's recipe calls for 1/2 cup of flour for a certain number of pancakes, and Abigail wants to make 60% more pancakes, then she will need 60% more flour. To calculate the amount of flour, we can multiply the original amount by 1.6 (which is 100% + 60%).
Flour needed = 1/2 cup * 1.6 = 0.8 cup
Therefore, Abigail will need to use 0.8 cup of flour to make 60% more pancakes than the original recipe.
Ben builds custom ladders of varying heights. He uses this equation to determine the number of rungs, r , to put on a ladder that has a height of h feet. r = h ÷ 0.8 What is the independent variable in this situation?
the height of the ladder
the number of ladders
the space between rungs on the ladder
the total number of rungs on the ladder
Answers
Ben builds ladders of different heights and put the number of rungs depending upon height of any particular ladder. He uses an equation for this construction that is given by :-
r = h ÷ 0.8
where h is the height of the ladder and r is the number of rungs in that ladder.
As we increase the height of the ladder, we need more rungs. If we decrease height, we would need lesser rungs.
Thereby, the number of rungs depend on the height of the ladder. It means value of r depends on value of h.
So r is dependent variable, and h is the independent variable.
Hence, option A is correct i.e. the height of the ladder.

A number cube is rolled 63 times. predict how many times the cube will land on a number that is a factor of 6 .
Answers
how many times you said
we need to find how many fulfill the condition
how many numbers from 1,2,3,4,5,6 are a factor of 6?
1 is a factor
2 is a factor
3 is a factor
6 is a factor
so 4 numbers
there are 6 sides, so we would expect it to land of a factor of 6 a grand total of 4/6 or 2/3 times
so 2/3 of the time we will get a factor of 6
so find 2/3 of 63 to get number of times we get a factor of 6
2/3 of 63=2/3 times 63=42
so it will land about 42 times
Final answer:
When a number cube is rolled 63 times, it is predicted to land on a factor of 6, specifically 1, 2, 3, or 6, a total of 42 times. This prediction is based on the probability of 2/3 for each roll to result in a factor of 6.
Explanation:
A student asked: A number cube is rolled 63 times. Predict how many times the cube will land on a number that is a factor of 6.
To answer this, we first identify the factors of 6 on a six-sided number cube, which are 1, 2, 3, and 6. Because each side of a perfectly weighted cube has an equal chance of landing face up, the probability of landing on a factor of 6 each time the cube is rolled is determined by the number of sides with factors of 6 out of the total number of sides. In this case, 4 out of the 6 sides are factors of 6 (1, 2, 3, and 6).
The probability of landing on a factor of 6 for each roll is 4/6, which simplifies to 2/3. To predict how many times the number cube will land on a factor of 6 in 63 rolls, we multiply the total number of rolls by the probability of landing on a factor of 6:
Predicted occurrences = Total rolls × Probability = 63 × (2/3) = 42
Therefore, we predict that the number cube will land on a factor of 6 a total of 42 times out of 63 rolls.

Answers
In order for us to solve this problem, we need to know how to find the area of the rectangle. There is a certain formula that we can use to find that, which I will go over in just a moment. I am also attaching am image alongside this answer to guide you in case you are a little bit confused or need extra studies.
Here, we can see the two dimensional cross section appear after the cut. Cross-section is the area of the figure that gets exposed after the cut is made, and in our case, it's a rectangle with measures 1m x 2m.
We need to set up an area formula in order to find the area of the cross-section.
[tex]A=l*w[/tex]
In our case, "l" stands for length and "w" stands for width. Let's substitute the values with the ones we know.
[tex]A=2*1 [/tex]
[tex]A=2[/tex]
Great. Question is solved, and we now know that the area of the cross-section is 2 m².
Answer: Area of the cross section is 2 m²
Jen Butler has been pricing speed pass train fares for a group trip to new york. three adult and four children must pay $122. two adults and three children must pay $87. find the price of the adult ticket and the price of the child
Answers
Let price of adult ticket is $x
And price of child ticket is $y
So we can make two equations using the given data
[tex] 3x+4y = 122 [/tex]
[tex] 2x+3y = 87 [/tex]
Now we can use eliminator method to solve the two equations
Multiply first equation by 2 and second equation by -3
[tex] 2(3x+4y = 122) [/tex]
[tex] -3(2x+3y = 87) [/tex]
[tex] 6x+8y = 244 [/tex]
[tex] -6x-9y =-261 [/tex]
now add both the equations so we get
[tex] 6x-6x+8y-9y=244-261 [/tex]
combine the like terms
[tex] -y=-17 [/tex]
Divide both sides by -1
[tex] y=17 [/tex]
Plug y=17 in any one of the equations to solve for x
[tex] 3x+4(17) = 122 [/tex]
[tex] 3x+68 = 122 [/tex]
Subtract 68 from both sides
[tex] 3x = 54 [/tex]
Divide both sides by 3
[tex] x=18 [/tex]
So x=18 and y=17
So
Price of adult ticket= $18
Price of child ticket = $17

isabella is covering a square tabletop with square mossaic tiles.the tabletop is 2ft. long and 2ft.wide.each tile is 1/4 in.long and 1/4in.wide.what is the minimum number of tiles needed to cover the tabletop?
Answers
24 ÷ (1/4) = (24/1) ÷ (1/4) = (24/1) × (4/1) = 96/1 = 96
96 tiles will fit across the tabletop.
Since the tabletop is as long as it is wide, that means we will have 96 rows of 96 tiles:
96(96) = 9,216 tiles to cover the tabletop.
Isabella needs a minimum of 9216 tiles to cover her 2ft by 2ft tabletop. This is calculated by converting all measurements to inches, finding the area of both the tabletop and a single tile, and dividing the total area of the tabletop by the area of a single tile.
Explanation:To answer Isabella's question let's first convert everything into the same units to make it easier. The tabletop in inches would be 2ft * 12in/ft = 24in by 24in. The area of the tabletop is then 24in * 24in = 576in^2. Each tile is 1/4in by 1/4in in size, so the area of a single tile is 1/4in * 1/4in = 0.0625in^2. To find the minimum number of tiles needed to cover the tabletop, divide the total area of the tabletop by the area of a single tile: 576in^2 / 0.0625in^2 = 9216 tiles. Therefore, Isabella needs a minimum of 9216 tiles to cover the square tabletop.

Edwina, Lexi and Luis plant a tree every 1/4 of a mile along the trail. Write and evaluate a división expression to find the number of trees they will plant. Show your work. Write your answer in simplest form
Answers
To calculate the number of trees planted, divide the total length of the trail by 1/4 mile, or multiply by 4. This will give the number of trees in simplest form once the trail length is known.
Explanation:To find the number of trees Edwina, Lexi, and Luis will plant along the trail, we need to divide the total length of the trail (in miles) by the distance between each tree (1/4 mile). Say the length of the trail is 'L' miles, the division expression will be L / (1/4). To evaluate this expression, remember that dividing by a fraction is the same as multiplying by its reciprocal. So the expression becomes L x 4, which gives the total number of trees planted along the trail. Without the specific length of the trail, we cannot calculate an exact number of trees. However, this formula helps us find the answer in simplest form once 'L' is known.

A box contains 2 green balls and 2 yellow balls. Reaching to the box and grab a yellow ball. Express the probability as a decimal.
Answers
Final answer:
The probability of grabbing a yellow ball from a box with 2 green and 2 yellow balls is 0.5, calculated by dividing the number of yellow balls by the total number of balls.
Explanation:
In probability, the chance of an event happening is expressed as a fraction of the number of successful outcomes over the number of total possible outcomes. Since there are 2 yellow balls and 4 balls in total, the probability (P) of drawing a yellow ball is calculated as follows:
Number of successful outcomes (yellow balls) = 2
Total number of possible outcomes (total balls) = 4
P(yellow ball) = Number of yellow balls / Total number of balls = 2/4 = 0.5
Therefore, the probability of grabbing a yellow ball is 0.5 when expressed as a decimal.
