Answer: 3070
Step-by-step explanation:
The city parks and recreation department has announced that it will have a swimming class if at least 24 people register for the class. So far, 9 people have registered. At least how many more people must register for the swimming class to be held?
In the city parks and recreation department has announced at least many more 15 people must register for the swimming class.
The city parks and recreation department has announced that it will have a swimming class, there are at least 24 people register for the class.
It is possible to register 9 people in each class.
Based on the given conditions, formulate,
⇒ least people registered for the class - far people have registered
So, we can write,
⇒ 24 - 9
Calculate the sum or difference,
⇒ 15 people
Therefore, At least many more people must register for the swimming class to be is equal to 15 people.

mrs adams buys 4 bannanas and 6 apples tell whether each statement is true or false
Answer:
The statement is false!Step-by-step explanation:
Since 4 bananas + 6 apples = 10 total fruit, the ratio of apples to total fruit is 6 to 10.A ball is dropped from a window and takes 2 seconds to reach the ground. it starts from rest and reaches a final speed of 20 m/s. what is the ball's acceleration?
Acceleration of the ball is 10 [tex]m/s^{2}[/tex].
The relation between initial velocity , final velocity , acceleration and time can be written as,
v = u + at
Here, v is the final velocity, u is the initial velocity, a is the acceleration and t is the time
Time taken by ball to reach the ground = t = 2 seconds.
As it starts from rest , initial velocity of ball = u = 0 m/s.
Final velocity of ball = v = 20m/s.
v = u + at equation 1
Put value of v = 20m/s , u = 0m/s and t = 2 seconds in equation 1.
(20m/s) = (0 m/s) + a (2 second)
a = ( 20m/s )/( 2second )
a = 10 [tex]m/s^{2}[/tex]
Acceleration of the ball is 10 [tex]m/s^{2}[/tex].

What is quadrant?
Each of the coordinate plane's four portions is referred to as a quadrant. In the first quadrant, all trig functions—sin, cos, tan, sec, csc, and cot—are positive. The second quadrant of sine has a positive value. Tangent in the third quadrant is positive. A positive cosine is present in the fourth quadrant.
Sin(20°)
20° is in the first quadrant. In quadrant 1, every trigonometric function is positive..
Sin(20) = 0.3420
Sin(340°)
340° is in the forth quadrant. The sin is minus in quadrant 4.
Sin(340) = -0.3420
Therefore, the value of sin 20 and sin 340 is 0.3420 and -0.3420 respectively

At a circus, tickets cost $6.75 per person. a family of four spent $73.00 on tickets and food. if each person spent an equal amount on food, how much did each person spend on food?
Answer:
$11.50
Step-by-step explanation:
6.75 times 4 is 27
$73-27 is 46
46 divided by 4 is 11.5
Answer:
$11.50
Step-by-step explanation:
Total spent = Food + Tickets
The cost of the tickets times the number of people
6.75 x 4 = $27.00 for tickets
then the total number of dollars spent in total subtracted by the amount for tickets
73 - 27 = $46 for food
$46 / 4 people = 11.50
So each person spent 11.50 on food.
1. ¿Cuál o cuáles son los interceptos con el eje x , de la función

3.Las soluciones de la ecuación
4.Usa la discriminante para determinar la naturaleza de las raíces de las ecuaciones.
5.Plantea una ecuación cuadrática para la parábola
Utilizando la formula de Bhaskara obtenemos los interceptos del eje x que son en x = 0.
La cuadratica con las dadas raices es:
f(x) = x^2 + 64
¿Como encontrar los interceptos con el eje x?
Primero tenemos la función cuadratica:
f(x) = 2x^2 - 6x + (9/2)
Primero, debemos encontrar las soluciones a la ecuación:
2x^2 - 6x + (9/2) = 0
Esto nos dara los interceptos con el eje x.
Usando la formula de Bhaskara obtendremos:
x = ( 6 ± √( (-6)^2 - 4*(9/2)*2 )/(2*2)
x = (6 ± 0)/4
Entonces tenemos dos interceptos del eje x en el mismo punto, que es x = 6/4 = 3/2
2) Ahora nos dan dos raices, que son x = 8 y x = -8
Recordar que si nos dan dos raices a y b, entonces una cuadratica con esa raices será:
f(x) = A*(x - a)*(x - b)
Donde A es el coeficiente lider de la cuadratica. En este caso no nos dan un valor de A, por lo que asumimos es 1.
Entonces esta cuadratica será:
f(x) =(x - 8)*(x + 8)
Expandiendo:
f(x) = x^2 + 64

A 2.36 cm3 sample of an unknown metal weighs 18.5 g. what is the sample's density?
The density of the sample is 796.61 kg/m^3.
According to teh given question.
The weight of the metal is 18.5g
The volume of the sample is 2.36 cm^3 or 0.00000236
Since, we know that
Weight = mass × acceleration due to gravity
⇒ 18.5g = mass of the metal × 9.8
⇒ 18.5g/1000 = mass of the metal × 9.8
⇒ mass of the metal = 0.00188kg
Therefore,
the density of the sample
= 0.00188/0.00000236
= 796.61 kg/m^3
Hence, the density of the sample is 796.61 kg/m^3.

Answer:
mean = 23
median = 22.50
mode = 20
range = 7.5
Step-by-step explanation:
mean is the total / n
total = 20+20+22.50+25+27.50 = 115
n= 5
mean = 115/5 = 23
median you'll arrange the numbers in ascending order and pick the middle one and its 22.50
20, 20, [22.50], 25, 27.50
mode is the number that is repeated mostly and it was 20.
range is max - min
max is 27.50
min is 20
range = 27.50 - 20
range = 7.50

line?
b = y + mx
O by- mx
=
b = y-m
b = -12
b = -4
b = 2
The equation that can be used to find the y-intercept of the line is
b = y - mx, and the y-intercept for this equation will be -12
In this question, It is given that a line passes through a given point (1,-8), and the slope of the line is given 4. We know the equation of Slope-point form : (y - y₁) = m(x - x₁), Where m = slope = 4 and (x1,y1) = (1,-8)
Now, putting these values into the slope-point form equation, We get :
=> (y - y₁) = m(x - x₁)
=> (y - (-8) = 4(x - 1) => (y +8) = 4x -4
=> y = 4x -12 ---> Equation (1)
We got the slope-intercept form for the following situation.
We can find out the y-intercept value by comparing the
=> y = mx + b to Equation (1).
=> b = -12
Hence, b = y - mx will be used to find out the y-intercept and the y-intercept for this line will be -12

A box contains 8 red marbles, 4 white marbles, and 6 blue marbles. if a marble is randomly selected from the box, what is the probability that it is red? express your answer as a fraction or a decimal number rounded to three decimal places, if necessary.
The probability of selecting red marble is 0.444.
Probability is calculated using the formula :
Probability = number of favourable outcomes ÷ total number of outcomes
Number of favourable outcomes = number of red marbles in box
Number of favourable outcomes = 8
Total number of outcomes = total number of marbles
Total number of outcomes = 8 + 4 + 6
Total number of outcomes = 18
Keep the values in formula of probability to find the probability of selecting red marble
Probability = 8 ÷ 18
Performing Division by 2
Probability = 4/9
Representing in decimal round to three decimal places = 0.444
Hence, the probability of selecting red marble is 0.444.
