Answer:
23.31 ft
Step-by-step explanation:
Reference angle = 47°
Opp = 25 ft
Adj = x
Apply trigonometry ratio TOA:
Tan 47 = Opp/Adj
Tan 47 = 25/x
x*Tan 47 = 25
x = 25/Tan 47
x = 23.3128772 ≈ 23.31 ft (to 2 d.p)
Malika bought 7 new pairs of shoes. Each pair of shoes cost the same amount and was discounted by $21.75.
Lauren paid a total of $654.50 before tax. How much was each pair of shoes before the discount?
A: $152.25
B: $93.50
C: $115.25
D: $71.75
Multiply the amount of the discount by pairs of shoes:
21.75 x 7 = 152.25
Add that to the total she spent:
152.25 + 654.50 = 806.75
Divide the total by pairs of shoes:
806.75/7 = $115.25
The answer is C. $115.25

Step-by-step explanation:
Many utility companies promote energy conservation by offering discount rates to consumers who keep their energy usage below certain established subsidy standards. A recent report notes that 60% of island residents of a country have reduced their electricity usage sufficiently to qualify for discounted rates. If five residential subscribers are randomly selected from a city on this island find the probability of each of the following events. (Round your answers to three decimal places.)
a. At least four qualify for the favorable rates.
b. All five quality for the favorable rates.
Answer: Many utility companies promote energy conservation by offering discount rates to ... who keep their energy usage below certain established subsidy standards. A recent EPA report notes that 70% of the island residents of Puerto Rico have reduced their electricity usage sufficiently to qualify for discounted rates.
Step-by-step explanation:
ONM has vertices O (-4, 2), N (3, 6) and M(0,3). What are the coordinates of the
vertices of O' N' M' if ONM is first translated (x, y)+(x + 3, y) followed by a
reflection across the line y = 1?
Answer:
The new vertices are [tex]O''(x,y) = (-1, 0)[/tex], [tex]N''(x,y) = (6,-4)[/tex] and [tex]M''(x,y) = (3,-1)[/tex].
Step-by-step explanation:
Previously, we have to define a vectorial equation for a reflection across the line [tex]y = 1[/tex]:
Reflection across the line y = 1:
[tex]P'(x,y) = P(x,y) -2\cdot [P(x,y) -(x_{P},1)][/tex] (1)
Where:
[tex]P(x,y)[/tex] - Original point.
[tex]x_{P}[/tex] - x-Coordinate of the original point.
[tex]P'(x,y)[/tex] - Resulting point.
Translation:
[tex]P'(x,y) = P(x,y) + (3,0)[/tex] (2)
If we know that [tex]O(x,y) = (-4,2)[/tex], [tex]N(x,y) = (3, 6)[/tex] and [tex]M(x,y) = (0,3)[/tex], then the resulting points are, respectively:
Point O'
Translation
[tex]O'(x,y) = O(x,y) + (3,0)[/tex]
[tex]O'(x,y) = (-1,2)[/tex]
Reflection
[tex]O''(x,y) = O'(x,y) -2\cdot [O'(x,y) -(x_{O'},1)][/tex]
[tex]O''(x,y) = (-1,2) -2\cdot [(-1, 2)-(-1,1)][/tex]
[tex]O''(x,y) = (-1, 0)[/tex]
Point N'
Translation
[tex]N'(x,y) = N(x,y) + (3,0)[/tex]
[tex]N'(x,y) = (6,6)[/tex]
Reflection
[tex]N''(x,y) = N'(x,y) -2\cdot [N'(x,y) -(x_{N'},1)][/tex]
[tex]N''(x,y) = (6,6) - 2\cdot [(6,6)-(6,1)][/tex]
[tex]N''(x,y) = (6,-4)[/tex]
Point M'
Translation
[tex]M'(x,y) = M(x,y) + (3,0)[/tex]
[tex]M(x,y) = (3,3)[/tex]
Reflection
[tex]M''(x,y) = M'(x,y) -2\cdot [M'(x,y) -(x_{M'},1)][/tex]
[tex]M''(x,y) = (3,3) - 2\cdot [(3,3)-(3,1)][/tex]
[tex]M''(x,y) = (3,-1)[/tex]
The new vertices are [tex]O''(x,y) = (-1, 0)[/tex], [tex]N''(x,y) = (6,-4)[/tex] and [tex]M''(x,y) = (3,-1)[/tex].

Which expression is equivalent to 1 2 ( 4 x + 8 ) ?
Answer:
48x + 96
Step-by-step explanation:
Given expression: 12(4x + 8)
Using the Distributive Property, we can simplify the given expression.
Distributive Property: [tex]a(b + c) = ab + ac[/tex]
Simplify:
[tex]\implies 12(4x+8)\\\\\implies 12(4x) + 12(8)\\\\\implies 48x + 96[/tex]
The expression that is equivalent to 12(4x + 8) is [tex]48x + 96[/tex].

Construct triangle ABC such that AB = 8cm, BC = 6.5 cm and angle ABC = 80 degree. Measure and write down the length of AC.
Answer:
AC = 9.39 cm
Step-by-step explanation:
sin 80 = m/8
m = 7.88
cos 80 = n/8
n = 1.39
p = 6.5 - 1.39 = 5.11
AC² = 7.88² + 5.11²
AC = 9.39 cm

¿ Cuál seria su velocidad
Si se tarda dos horas?
para
llegar
Answer:
60 millas por hora.
Step-by-step explanation:
Dado que un taxi viaja a una velocidad de 48 mph para llegar a un destino en 2 horas y media, para determinar cuál seria su velocidad si se tarda dos horas para llegar se debe realizar el siguiente cálculo:
48 x 2.5 = 120
120 / 2 = X
60 = X
Así, su velocidad, si se tardase dos horas en llegar, sería de 60 millas por hora.
