Answer:
t ≤ 9 hours
Step-by-step explanation:
Reservation fee = $18
Additional fee per hour = $6
Let x = number of hours
At most in inequality means ≤ less than or equal to
The inequality is
18 + 6t ≤ 72
6t ≤ 72 - 18
6t ≤ 54
t ≤ 54/6
t ≤ 9 hours

Answer:
Answer:

Step-by-step explanation:
Given
See attachment for triangle
Required
Find x
To find y, we make use of the relationship between sides lengths 11 & x and angle 37
The relationship is:
[tex]cos(37) = \frac{11}{x}[/tex]
i.e.
[tex]cos(\theta) = \frac{Adjacent}{Hypotenuse}[/tex]
Make x the subject
[tex]x = \frac{11}{cos(37)}[/tex]
[tex]x = \frac{11}{0.7986}[/tex]
[tex]x = 13.7741[/tex]

Can I Get Help Pls Damon drew a scale drawing of a swimming pool. The scale he used was 1 inch : 9 feet. The diving board is 2 inches long in the drawing. How long is the actual diving board?
Answer: 18 ft
Step-by-step explanation:
Given
Scale is 1inch:9 feet
1 feet= 12 inch
The dividing board is 2 inches long
Suppose the actual length of the diving board is x
[tex]\therefore \dfrac{1}{9\times 12}=\dfrac{2}{x}\\\\\Rightarrow x=\dfrac{9\times 12\times 2}{1}\\\\\Rightarrow x=216\ inch\ \text{or}\ 18\ ft[/tex]

f(7)=
g(7)=
The equation for f(x) is
The equation for g(x) is
Answer: f(7) = -128
g(7) = 26
Equation of f(x): f(x)= -11x-51
Equation of g(x): g(x)=3x+5
Step-by-step explanation:
Rate of change of a function: [tex]\dfrac{f(x_2)-f(x_1)}{x_2-x_1}[/tex]
From the table. Rate of change in f(x)= [tex]\dfrac{f(1)-f(0)}{1-0}=\dfrac{-62+51}{1}=-11[/tex]
Rate of change in g(x)= [tex]\dfrac{g(1)-g(0)}{1-0}=\dfrac{8-5}{1}=3[/tex]
Also, the rate of change throughout the function is the same, hence both are linear functions.
Equation of linear function: [tex]f(x)=mx+c[/tex], where m= rate of change of function, c = f(x) at x=0.
From table, f(0)= -51 , g(0)=5
Equation of f(x): f(x)= -11x-51
Equation of g(x): g(x)=3x+5
f(7) = -11(7)-51 = -77-51 = -128
g(7) = 3(7)+5 = 21+5 = 26
f(7) = -128
g(7) = 26

Answer:
x = 557 to the nearest whole number
Step-by-step explanation:
The triangle is divided into two right triangles
Using the SOH CAH TOA identity
tan theta = opp/adj
tan 29 = (x/2)/502
x/2 = 502 tan 29'
x/2 = 278.26
x = 278.26 * 2
x = 556.52
x = 557 to the nearest whole number

Un albañil pone azulejos a una pared de 6 m de largo y 2,4 m de alto.Los azulejos son cuadrados de 20 cm de lado
Pregunta completa:
Un albañil pone azulejos a una pared de 6 m de largo y 2,4 m de alto. Los azulejos son cuadrados de 30 cm de lado. ¿Cuants, cajas tendra que comprar si en una caja hay 25 azulejos? Con procedimiento.
Respuesta:
160 tejas
7 cajas
Explicación paso a paso:
Dimensión de la pared = 6 m por 2,4 m
Área de la pared = 6 m * 2,4 m
Área de la pared = 14,4 m²
Longitud lateral, s de teja cuadrada = 30 cm = 0,3 m
Área de la loseta cuadrada = s² = 0.3² = 0.09m²
Número de baldosas cuadradas necesarias:
14,4 m² ÷ 0,09 m²
= 160 fichas cuadradas
Si hay 25 fichas en una caja;
Número de cajas a comprar:
160/25
= 6,4 ≈ 7 cajas

In a school election, 100 students submit ed a ballot voting for either Patrick or Britney. After counting all the votes, Britney received 56 more votes than Patrick. How many students voted for Patrick?
Answer:
22 students
Step-by-step explanation:
Create a system of equations where p is the number of students that voted for Patrick, and b is the number that voted for Britney
p + b = 100
b = p + 56
Solve by substitution by plugging in p + 56 as b in the first equation
p + b = 100
p + p + 56 = 100
Solve for p:
2p + 56 = 100
2p = 44
p = 22
So, 22 students voted for Patrick
Patrick sold 22 ballots.
22+56=78
22+78=100

Mr. Roy is scheduled to work less than 18 hours this week. He has already worked 7 hours. If x is the remaining number
of hours Mr. Roy could work this week, which inequalities represent the number of remaining hours
Mr. Roy could be
scheduled to work this week? Select all that apply.
A 2+7 > 18
B 2 + 7 < 18
C 2 +18 > 7
DI > 11
EI < 11
Answer:
x + 7 > 18
Step-by-step explanation:
Answer:
The answer should be B
Step-by-step explanation:
Assuming x is the 2 then 2+7 should equal 9 and 9 would represent less than the amount Roy wanted to work out which would be the ideal one for him since he wanted to work out less than 18 hours.
Imagine the center of the Seattle Great Wheel is located at (0, 0) on a coordinate grid and the radius lies on the x-axis. Write an equation of a circle for the Seattle Great Wheel and then sketch an image of your equation on the graph provided or insert your own graph.
Center is 0,0 and diameter is 175
Answer:(x-0)^2 + (y-0)^2=30^2
Step-by-step explanation:
The equation of the circle is x^2 +y^2 = 7656.25
How to determine the equation of the circle?The given parameters are:
Center = (0,0)
Diameter = 175
The equation of a circle is represented as:
(x - a)^2 +(y - b)^2 = r^2
Where
Center = (a,b) = (0,0)
r = radius = 175/2
So, we have:
(x - 0)^2 +(y - 0)^2 = (175/2)^2
Evaluate
x^2 +y^2 = 7656.25
Hence, the equation of the circle is x^2 +y^2 = 7656.25
