Answer:
15 days
Step-by-step explanation:
The cost for boarding is $18 each day. The cost for play-time is $6.75 each day. So, the charges for both add up to ...
$18 +6.75 = $24.75
each day.
The manners lesson is a flat fee added to the daily boarding charges, so for d days, the total bill is ...
$24.75·d +45.99 = 417.24 . . . . . equation relating days to cost
We solve this 2-step equation by first subtracting the constant on the left.
$24.75·d = $371.25
Then we divide by the coefficient of the variable:
d = $371.25/$24.75
d = 15

During a scuba dive, Lainey descended to a point 26 feet below the ocean surface. She continued her descent at a rate of 26 feet per minute. Enter an inequality you could solve to find the number of minutes she can continue to descend if she does not want to reach a point more than 78 feet below the ocean surface. Use t to represent the variable for the minutes Lainey can continue to descend.
Answer:
t ≤ 2
Step-by-step explanation:
Given that:
Initial Position = - 26 feets (below surface)
Descent rate = 26 feets per minute
Maximum depth = 78 feets
Let t = number of minutes
Hence,
Initial position + (descent rate * number of minutes) ≤ - 78
-26 + (- 26t) ≤ - 78
-26t ≤ - 78 + 26
-26t ≤ - 52
t ≤ 52/26
t ≤ 2
Consider the function f(x) = 3x - 2 and the function g(x), which is represented by the table below. Which of the following statements about f(x) and g(x) is true? Select all that apply.
1. The slope of f(x) is smaller than the slope of g(x)
2. The lines represented by f(x) and g(x) are parallel.
3. The line represented by f(x) crosses the x-axis to the right of the line represented by g(x).
4. The y-intercept of f(x) is smaller than the y-intercept of g(x).
5. The values of f(x) and g(x) are the same at x = 3
Answer:
4. 5. 3. are correct im pretty sure
Step-by-step explanation:
Statements 1, 2, and 3 about f(x) and g(x) are "true".
What are the functions?The function is defined as a mathematical expression that defines a relationship between one variable and another variable.
Consider the function f(x) = 3x - 2 and the function g(x), which is represented by the table below.
x : 1 3 5 7 9
g(x): 3 7 11 15 19
Here the slope of the function g(x) is 2.
This means statements 1 and 2 are false because slopes are different.
To compare the position of the lines at the x-axis, you can evaluate the function at x=0. f(0) = 3×0 - 2 = -2 and g(0) = -1.
Since g(0) is less than f(0), the line represented by g(x) crosses the x-axis to the right of the line represented by f(x). So, statement 3 is true.
The y-intercept of f(x) is -2, while the y-intercept of g(x) is 1. So, statement 4 is true.
To compare the values of f(x) and g(x) at x=3, you can evaluate the functions at x=3. f(3) = 3×3 - 2 = 7 and g(3) = 7. So, the values of f(x) and g(x) are the same at x=3. So, statement 5 is true.
Therefore, the true statements are 2, 3, and 4.

A car salesperson sells a car for $21,000. She receives a 5.25% commission on the sale of the car.
How much did she earn on the sale?
Answer:
She earned 1102.50 from the sale.
Step-by-step explanation:
I'd say break the percentage down
5.25÷100=0.0525
21,000×0.0525=1102.5 or 1102.50
Which of the following is the converse of the Triangle Proportionality
Theorem?
A. If a line divides two sides of a triangle proportionally, then it is
parallel to the third.
B. If a line is perpendicular to one side of a triangle, then it divides
the other two sides proportionally.
C. If a line is parallel to one side of a triangle, then it divides the other
two sides proportionally.
D. If a line divides two sides of a triangle proportionally, then it is
perpendicular to the third.
I’m
Answer:
The answer is A
Step-by-step explanation:
The correct answer is:
A) If a line divides two sides of a triangle proportionally, then it is
parallel to the third.
What is triangle proportionally?If a line is drawn parallel to any one side of a triangle so that it intersects the other two sides in two distinct points, then the other two sides of the triangle are divided in the same ratio.
The converse of the triangle proportionality theorem states "If a line divides two sides of a triangle proportionally, then that line is parallel to the third side."
Hence, the converse will be If a line divides two sides of a triangle proportionally, then it is parallel to the third.

A new neighborhood activity complex is being built in Erie. The perimeter of the rectangular playing field is 448 yards. The length of the field is 6 yards less than quadruple the width. What are the dimensions of the playing field?
Answer:
Length = 178 yards and Breadth = 46 yards
Step-by-step explanation:
The perimeter of the rectangular field is 448 yards
Let the width is b and the length of the field is (4b-6) yards
We need to find the dimensions of the playing field. We know that the perimeter of a rectangle is given by :
P = 2(l+b)
ATQ,
[2((4b-6)+b)] = 448
2(5b-6) = 448
5b-6 = 224
5b = 230
b = 46 yards
Length = (4b-6)
= 4(46) - 6
= 178 yards
Hence, the length and breadth of the field is 178 yards and 46 yards respectively.

Olivia baked 45 mini-loaves of banana bread to be sliced for snacks at a craft fair. She will place an equal number of loaves in 6 different locations. What if Olivia wants to put only whole loaves at each location? How many loaves will be at each location?
Answer:
7 whole loaves of bread.
Step-by-step explanation:
Since there are total of 6 locations and each location needs to have the same number of whole loaves of bread we simply need to divide the number of mini-loaves of banana bread by the number of locations like so...
45 / 6 = 7.5
As we can see by the mathematical expression above 45 loaves of bread can be divided into 6, giving each location 7.5 loaves of bread but since each location needs only whole loaves then that would mean that each location would get 7 whole loaves of bread.

Equivalent Expressions
Algebraic expressions can be given in different forms when applying properties of the basic operations.
The given expression is:
2(1.7x + 3.3) + 5(2.6x + 1.4)
Multiplying both parentheses by the outer factor:
3.4x + 6.6 + 13x + 7
Combining like terms:
16.4x + 13.6

Agustín fabrica artículos de cuero y los vende con un incremento del 8% de su costo. Si en su última campaña utilizó un cuero de mayor calidad y aplicó un incremento adicional de 12%, ¿cuál fue el aumento único equivalente del precio?
Answer:
El aumento del precio de costo único equivalente es un aumento del 20,96% en el precio de costo
Step-by-step explanation:
Los parámetros dados son;
El porcentaje de aumento en el precio de costo que Augustin vende artículos de cuero = 8%
El aumento adicional de Augustin se aplica cuando usó cuero de mayor calidad = 12%
Sea x el precio de costo
Tenemos, el primer precio de venta = 1.08 × x
El precio de venta del cuero de alta calidad = 12% adicional al precio de venta anterior
∴ El precio de venta del cuero de alta calidad = 1,12 × 1,08 × x = 1,2096 × x
Por lo tanto, el precio de venta del cuero de alta calidad = (1.2096 × 100)% de x = 120.96% de x, lo que da;
El aumento del precio de costo único equivalente = (120,96% - 100%) aumento en x = 20,96%
∴ El aumento del precio de costo único equivalente = 20,96% de aumento en el precio de costo.

Write an equation in point-slope form of the line that passes through the given point and with the given slope m.
(-4,1) m=4
The equation of the line is ?
Answer:
An equation in point-slope form of the line that passes through the given point and with the given slope m = 4 will be:
[tex]y-1 = 4(x-(-4))[/tex]
Step-by-step explanation:
Given
The point = (-4, 1)m = 4Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
here:
m = slope(x₁, y₁) = pointsubstituting the values m = 4 and the point (-4, 1) in the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-1 = 4(x-(-4))[/tex]
Thus,
An equation in point-slope form of the line that passes through the given point and with the given slope m = 4 will be:
[tex]y-1 = 4(x-(-4))[/tex]
Note: It can further be simplified
[tex]y-1=4\left(x+4\right)[/tex]
Add 1 to both sides
[tex]y-1+1=4\left(x+4\right)+1[/tex]
[tex]y=4x+17[/tex]
