what’s the answer for this question
Answer:
It's app. 50.24
Step-by-step explanation:
The area of a circle is A = pi * r ^2
So the area is
= pi * 16
in the question it says to use 3.14 for pi instead
so multiply 16 * 3.14 = 50.24
Answer:
50.24 square miles
Step-by-step explanation:
The formula for the area of a circle is A=[tex]\pi r^{2}[/tex]
Plug in 3.14 for pi and 4 for r
when you square the 4, you get 16
16 x 3.14 is 50.24

At the movie theater, tickets for children cost blank each and adult tickets cost $8.75 each. If ticket sales for a group of 35 people totaled $259, how many children were in this group?
11 children approx.
Let's denote the number of children's tickets as x and the number of adult tickets as y
Since each child ticket costs $4.50 and
each adult ticket costs $8.75,
we can set up the following equations based on the given information:
The total number of people= 35:
x + y= 35
The total revenue from ticket sales= $259:
4.50x + 8.75y = 259
Now we can solve this system of equations to find the values of x and y:
We can start by solving equation 1 for y :
y= 35 - x
Then substitute this expression for y into equation 2:
4.50x + 8.75(35 - x) = 259
Now, solve for x:
4.50x + 306.25 - 8.75x = 259
4.50x - 8.75x = 259 - 306.25
-4.25x = -47.25
Divide both sides by -4.25:
x = (-47.25) / (-4.25)
x = 11.12 approx.
Since the number of children must be a whole number, we can round to the nearest whole number.
So, approximately 11 children were in this group.

Express the ratio as a fraction in simplest form:18 ounces to 3 cups. (Hint) 1 cup = 8 ounces
The ratio 18 ounces to 3 cups is equivalent to 18 ounces to 24 ounces. This is expressed as the fraction 18/24, which simplifies to 3/4 when you divide the numerator and denominator by their greatest common divisor (6).
Explanation:To express the ratio 18 ounces to 3 cups as a fraction in simplest form, we first need to convert the cups to ounces using the provided conversion factor (1 cup = 8 ounces). Therefore, 3 cups is 3 * 8 = 24 ounces.
So, the original ratio of 18 ounces to 3 cups is equivalent to a ratio of 18 ounces to 24 ounces. This can be written as the fraction 18/24. To simplify this fraction, we find the greatest common divisor (GCD) of 18 and 24, which is 6. We then divide both the numerator (18) and the denominator (24) by this GCD.
Doing so, we get 18/24 = 3/4. Therefore, the ratio 18 ounces to 3 cups expressed as a fraction in simplest form is 3/4.

The ratio as a fraction in simplest form is 18/24 to get 3/4.
Convert cups to ounces:
3 cups = 3 * 8 ounces
= 24 ounces
The ratio is 18 ounces to 24 ounces, which can be written as the fraction
= 18/24.
GCD of 18 and 24= 6.
18 ÷ 6 = 3
24 ÷ 6 = 4
So, [tex]\frac{18}{24}[/tex] simplifies to [tex]\frac{3}{4}[/tex].
Thus, the ratio of 18 ounces to 3 cups in simplest form is 3/4.

Suppose that triangle ABC is dilated to A'B'C' by a scale factor of 4 with a center of dilation at the origin. What is the distance from the center of dilation to the midpoint of B'C'?
The distance from the center of dilation to the midpoint of B'C' is 4 times the original distance from the center to the midpoint of BC, given the dilation scale factor is 4.
Explanation:To find the distance from the center of dilation to the midpoint of B'C', we use the properties of dilations in geometry. Since triangle ABC is dilated with a scale factor of 4, every length in triangle ABC is multiplied by 4 to get the corresponding length in triangle A'B'C'. If the original distance from the center of dilation (the origin) to the midpoint of BC was 'x', then after the dilation, the distance from the center (the origin) to the midpoint of B'C' is 4x. If the original distance x is known, we calculate the dilated distance by multiplying x by the scale factor of 4.
Tickets to a concert are $35 each. In addition to the cost for the tickets ordered, there is a $15 processing charge per order.
Write an expression that represents the total cost of an order of n number of tickets.
The total cost of an order of n concert tickets, with each ticket costing $35 and a fixed processing charge of $15, is represented by the expression 35n + 15.
To represent the total cost of an order of n number of tickets, we need to account for the cost of each ticket as well as the processing charge that applies to the entire order. The cost of one ticket is $35, and thus for n tickets, the total cost for the tickets alone would be 35n dollars. Since the processing charge is a fixed amount per order, not dependent on the number of tickets, we add the flat fee of $15 to the cost of the tickets. Therefore, the expression for the total cost of the order is 35n + 15.

A filing cabinet has a height of 4 feet and a length of 2 feet. The volume of the filing cabinet is 24 cubic feet. What is the width of the filing cabinet
Answer:
3 ft
Step-by-step explanation:
To find the width of the cabinet, we can use the formula:
length x width x height = volume
By plugging in the information that the problem gives, we can now solve this problem:
2 ft x 4 ft x width = 24 ft
8 ft x width = 24 ft
width = 24 ft / 8 ft
width = 3 ft
The width of the filing cabinet is found by dividing the volume (24 cubic feet) by the product of the length (2 feet) and height (4 feet), which results in a width of 3 feet.
A filing cabinet with a height of 4 feet and a length of 2 feet has a volume of 24 cubic feet. To find the width of the filing cabinet, we can use the formula for the volume of a rectangular solid: V = l x w x h. Given that V = 24, l = 2, and h = 4, substitute these values into the formula and solve for w:
Volume = length x width x height
24 = 2 x width x 4
width = 24 / (2 x 4) = 24 / 8 = 3.
Therefore, the width of the filing cabinet is 3 feet.

Which side lengths form a right triangle?
Choose all answers that apply:
A 2,15, 17
B 1,8, √65
C 2,√80 , 9
Answer:
B. 1,8, root65
Step-by-step explanation:
[tex]a^{2} + b^{2} = c^{2}[/tex]
[tex]1^{2}[/tex] = 1
[tex]8^2[/tex] = 64
[tex](\sqrt{65})^{2}[/tex] = 65
1 + 64 = 65
Final answer:
Only the set of side lengths B (1, 8, √65) forms a right triangle, according to the Pythagorean theorem, as 1^2 + 8^2 equals (√65)^2.
Explanation:
The question asks which set of side lengths form a right triangle. According to the Pythagorean theorem, in a right triangle, the sum of the squares of the two shorter sides (legs) equals the square of the longest side (hypotenuse), which can be expressed as a^2 + b^2 = c^2.
To determine if each set of side lengths forms a right triangle, we can check each option using the Pythagorean theorem:
A: 2, 15, 17 - Check if 22 + 152 = 172.
B: 1, 8,
√65 - Check if 12 + 82 = (
√65)2.
C: 2,
√80, 9 - Check if 22 + (
√80)2 = 92.
After the calculations, we find that:
4 + 225 = 229, which is not equal to 289 (172).
1 + 64 = 65, which is equal to 65 ((
√65)2).
4 + 80 = 84, which is not equal to 81 (92).
Thus, only option B (1, 8,
√65) forms a right triangle.

Yasmine has 4 containers of 4 different colors of flowers to plant. She had 1/3 of each color left over when she was done planting. Yasmine said she had planted more than 2 1/2 of the original 4 containers. Use what you know about fractions to determine the total amount of containers of flowers she planted.
Answer:
[tex]2\frac{2}{3}[/tex]
Step-by-step explanation:
Given the information
4 containers of 4 different colors1/3 of each color left overShe had planted more than 2 1/2 of the original 4 containers=> Total color were left = 1/3 x 4 = 4/3 of the original containers
=> Total color were planted = (1 - 1/3) x 4 = 2/3 x 4 = 8/3 of the original containers
However, 8/3 = [tex]2\frac{2}{3}[/tex] > 2[tex]\frac{1}{2}[/tex]
So she is true, hence, the fractions to determine the total amount of containers of flowers she planted is: [tex]2\frac{2}{3}[/tex]

The next model of a sports car will cost 11.2% less than the current model. The current model costs $36,000. How much will the price decrease in dollars? What will be the price of the next model?
Answer:
The decrease in the price will be $4032
The price of the next model is $31968
Step-by-step explanation:
The current model costs $36,000.
The next model of a sports car will cost 11.2% less than the current model
So, decrease in price =[tex]11.2\% \times 36000[/tex]
=[tex]\frac{11.2}{100} \times 36000[/tex]
=4032
So, the price of next model decrease by $4032
So, the price of the next model= 36000-4032 =31968
Hence the price of the next model is $31968
