Selena spends $53.94 to buy a necklace and a bracelet set for each of her friends. Each necklace cost 9.99, and each bracelet costs 7.99. How many necklace and bracelet sets, s, did selena buy?
Answer:
3 sets
Step-by-step explanation:
each set is 17.98 (adding necklace and bracelet)
Total is 53.94
dividing 53.94 (amount spent) by 17.98 (cost of set)
Results in 3 sets
Answer:
She bought 3 necklace and bracelet sets
If i can be brainliest that would be great
Step-by-step explanation:
Each set contains a necklace and a bracelet
∵ Each necklace cost $9.99
∵ Each bracelet cost $7.99
∴ The cost of one set = (9.99 + 7.99)
∵ She spent on them $53.94
- Add the cost of a necklace and the cost of a bracelet and
multiply the sum by x and then equate the product by 53.94
∴ (9.99 + 7.99)x = 53.94
∴ 17.98 x = 53.94
- Divide both sides by 17.98
∴ x = 3

A giant water lily pad is shaped like a circle with a diameter of up to 9 feet. Find the circumference and area of the pad. Use 3.14 for π. Round to the nearest tenth. Drag and drop the numbers into the boxes to show the circumference and area of the pad.
(fill in the blanks)
The circumference of the lily pad is about [ ] ft.
The area of the lily pad is about [ ] ft^2.
(options for both: 14.1, 63.6, 254.3, 28.3)
Answer:
Circumference of the lily pad is about 28.3 ft
Area of the lily pad is about 63.6 ft²
Step-by-step explanation:
Formula for circumference of circle is,
Circumference = 2 π r
Given that diameter is 9 ft. Therefore radius is half of diameter.
[tex]r=\dfrac{d}{2}[/tex]
Substituting the values,
[tex]r=\dfrac{9}{2}=4.5[/tex]
Also value of π = 3.14
Substituting the value,
C = 2 × 3.14 × 4.5
Simplifying,
C = 28.26 ft
Rounding to nearest tenth value of circumference is C = 28.3 ft.
Formula for area of circle is,
A = π r²
Substituting the values,
A = 3.14 × 4.5²
Simplifying,
A = 63.585 ft².
Rounding to nearest tenth value of area is A = 63.6 ft².

Answer:
32.5
Step-by-step explanation:
there are 4 rows
1 = 3
2 = 5
3 = 2
so there is 10 numbers
We go for the middle number which is 2-3 so the answer must be 32.5.
We know it is between 2-3 as the same as 1-10

So the imput numbers are listed 2 + 3 in your stem diagram where so 5 + 6 would be in the explanation. As 10 +1 = 11 then 11/2 = 5.5 - this means 5.5 = 32.5 as 33 would be the 6.

If the equal sides of an isosceles right triangle measure 12 units then the measure of the hypotenuse is
Answer:
16.97056275
Step-by-step explanation:
12 squared + 12 squared = 288
square root of 288 = 16.97056275
The measure of the hypotenuse of an isosceles triangle with equal sides measureing 12 units is 16.97 units
What is an isosceles triangle?An isosceles triangle is a triangle that has two of its sides equal to each other . The base angle is also equal to each other.
The isosceles triangle is a right triangle. Since, one of the leg is 12 units, the other leg is also 12 units.
Using pythagora's theorem,
c² = a² + b²
c = √12² + 12²
c = √144 + 144
c = √288
c = 16.9705627485
c = 16.97 units
Therefore, the length of the hypotenuse is 16.97 units.

7. A box contains fifteen billiards balls, numbered 1 through 15. Anna draws a ball, records the number, and then returns it to the box. Then Vicki draws a ball. Find the probability of getting a 9 then a 3. *
The probability of first drawing a ball numbered 9 and then drawing a ball numbered 3, with each ball being returned to the box between draws, is 1 in 225.
Explanation:The question is about calculating the probability of two specific events occurring consecutively when drawing billiard balls from a box that contains numbers 1 through 15. We focus on the probability of first drawing a ball numbered 9 and then, after returning it, drawing a ball numbered 3. Since each ball is returned to the box before the next draw, the number of possible outcomes does not change between draws.
For the first draw, the probability of drawing a 9 is 1 out of 15 (since there is one '9' ball and 15 total balls). When the 9 ball is returned, the probability of drawing a 3 on the second draw is also 1 out of 15. Because these two events are independent (the outcome of the second draw does not depend on the outcome of the first), we multiply the probabilities of each event to find the overall probability of both events occurring:
Probability of drawing a 9 and then a 3 = (1/15) * (1/15) = 1/225.
This means there is a 1 in 225 chance of drawing a 9 followed by a 3 when both balls are returned to the box in between draws.

Which of the following is true of functions and their inverses?
The inverse of a quadratic function is not a function.
The inverse of a quadratic function is always a function.
The inverse of a linear function is not a function.
The inverse of a linear function is always a function.
The inverse of a quadratic function is not always a function, as it can assign multiple outputs to a single input. Conversely, the inverse of a linear function is always a function because it strictly assigns one output to each input.
Explanation:The presented statements about the nature of functions and their inverses are particularly related to the definition of a function. A function is a rule which assigns to each input exactly one output. Considering this, the inverse of a quadratic function is not always a function because it can assign multiple outputs (y-values) to a single input (x-value). This is why the graph of a quadratic function doesn't pass the 'horizontal line test', which is a criterion for a graph to represent a function.
On the other hand, the inverse of a linear function is indeed always a function. Because a linear function always assigns exactly one output to each input, its inverse will also satisfy the definition of a function.

Answer:
D The model indicates that 1-bedroom apartments in New York had an average rent of 800 dollars in 2000.

1-bedroom apartments in New York had an average rent of 800 dollars in 2000
The best interpretation of this y-intercept is the model indicates that 1-bedroom apartments in New York had an average rent of 800 dollars in 2000.
What is y-intercept of a function?The intersection of the graph of the function with the y-axis gives y-intercept of that function.
The y-intercept is the value of y on the y-axis at which the considered function intersects it.
Thus, y-intercept of y = f(x) is y = f(0)
In this case, x be the number of years after the year 2000.
Then we can show that x = 0, represents the year 2000 itself.
Now, the y-intercept is the value of y when we have x = 0.
So, the y-intercept gives information about the average price of a 1-bedroom apartment in the year 2000.
The information that we can conclude with this is the model indicates that 1-bedroom apartments in New York had an average rent of 800 dollars in 2000.

Given the rectangle of 3cm by 4cm and a circle of 1 cm inside it:
The Area of the shaded portion =Area of Rectangle-Area of Circle
Area of a Rectangle=Length X Width[tex]=3 X 4 =12cm^2[/tex]
Area of the circle =[tex]\pi r^2=\pi X 1^1=3.142cm^2[/tex]
Area of the shaded portion=12-3.142
[tex]=8.86cm^2[/tex]
The area of the shaded region inside the rectangle but outside the circle is 8.86 cm².
Explanation:A circle with a radius of 1 cm sits inside a rectangle with dimensions of 3 cm by 4 cm. To solve this problem, we can use the formula to find the area of a rectangle and the area of a circle.
The area of the rectangle is calculated by multiplying its length by its width, giving us an area of 12 cm². The area of the circle can be found using the formula A = πr², where A represents the area and r represents the radius.
Plugging in the given radius of 1 cm, we find that the area of the circle is π cm², which is approximately 3.14 cm². Therefore, the area of the shaded region (the region inside the rectangle but outside the circle) is 12 cm² - 3.14 cm² = 8.86 cm².

The resultant function of the parent function f(x) = x², which is translate left 5 units and down 1 unit, is f(x) = (x+5)^2-1.
What is transformation of a function?Transformation of a function is shifting the function from its original place in the graph.
Types of transformation-
Horizontal shift- Let the parent function is f(x). Thus by replacing parent function with f(x-b) shifts the graph b units right and by replacing parent function with f(x+b) shifts the graph b units left.Vertical shift- Let the parent function is f(x). Thus by replacing parent function with f(x)-c shifts the graph c units down and by replacing parent function with f(x)+c shifts the graph c units up.The given function is,
[tex]f(x) = x^2[/tex]
It has to be translated left 5 units. For this we have to add 5 units in the above function. Thus the function become,
[tex]f(x) = (x+5)^2[/tex]
Now the function is translated down 1 unit. For this we have to substract 1 units outside of the above function. Thus the function become,
