Answer:
15t+9 ft
Step-by-step explanation:
Given data
Width= 6t-1.5 ft
Length= 1.5t+6 ft
Required
The perimeter
The expression for perimeter is
P= 2L+2W
P= 2(1.5t+6)+ 2(6t-1.5)
open bracket
P= 3t+12+ 12t-3
collect like terms
P= 3t+12t+12-3
P= 15t+9 ft
Hence the perimeter is 15t+9 ft
La temperatura mínima en una ciudad el día lunes fue de –2 ºC y la máxima fue de 7 ºC. ¿Cuál fue la variación de temperatura en el día?
Answer:
La variación de temperatura en el día es 9°C.
Step-by-step explanation:
Cuando tenemos dos valores, uno máximo M y uno mínimo m, la variación entre esos valores es la diferencia (la resta) entre el valor máximo M y el valor mínimo m
variación = M - m
En este caso sabemos que la temperatura mínima es -2°C
La temperatura máxima es 7°C
La variación sera entonces:
Variación = 7°C - (-2°C)
Recordar la regla de los signos:
(-)*(-) = (+)
Entonces:
Variación = 7°C - (-2°C) = 7°C + 2°C = 9°C
La variación de temperatura en el día es 9°C.
Suppose the depth of the tide in a certain harbor can be modeled by y = 23 - 5 cos (6.), where y is the water depth in fect
and t is the time in hours. Consider a day in which t= 0 represents 12:00 midnight. For that day, when are high tide and
low tide and what is the depth of each?
a. high tide at 6:00 a.m. and 6:00 p.m., depth 28 ft
low tide at 12:00 noon and 12:00 midnight, depth 18 ft
b. high tide at 6:00 a.m. and 6:00 p.m., depth 23 ft
low tide at 12:00 noon and 12:00 midnight, depth 5 ft
c. high tide at 12:00 noon and 12:00 midnight, depth 28 ft
low tide at 6:00 a.m. and 6:00p.m., depth 18 ft
d. high tide at 12:00 noon, depth 23 ft
low tide at 6:00 a.m., depth 5 ft
High tide at 6:00 a.m. and 6:00 p.m., depth 23 ft low tide at 12:00 noon and 12:00 midnight, depth 5 ft. Therefore, option B is the correct answer.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
The given trigonometric function is y=23-5cos(πt/6).
The given equation is y=23-5cos(πt/6), where y is the water depth in feet and t is the time in hours.
To find the high and low tide depths, we need to find the maximum and minimum values of y.
The maximum value of y is obtained when cos(πt/6) = -1, which gives y = 23 - 5(-1) = 28 ft.
The minimum value of y is obtained when cos(πt/6) = 1, which gives y = 23 - 5(1) = 18 ft.
To find the time when high and low tide occur, we need to find the values of t when cos(πt/6) equals -1 and 1 respectively.
When cos(πt/6) = -1, we get πt/6 = 3π/2, which gives t = 12 hours.
When cos(πt/6) = 1, we get πt/6 = 0, which gives t = 0 hours.
Since t = 0 represents 12:00 midnight, we can conclude that high tide will occur at 6:00 a.m. and 6:00 p.m., with a depth of 28 ft, and low tide will occur at 12:00 noon and 12:00 midnight, with a depth of 18 ft.
Therefore, option B is the correct answer.

Answer:
60º
Step-by-step explanation:
A triangle is 180º so you do (180-60)/2 and you get that x=60.
Hope that helps :)
Answer:
Hey love! x = 60
Step-by-step explanation:
Because a triangle adds up to 180 so
180 - 60 = 120 and sense both angles will be the same measure I divide 120 by 2 and get 60 so
x =60 Hope that helps!

Step-by-step explanation:
p = 20 + 12 + 12 + 8 + 6 + 6 + 8 = 72
a = (20 x 12) - ( (6 x 4) / 2) = 240 - (24 / 2) = 240 - 12 = 228
While rowing in a race, John does 3960 J of work on the oars in 60 s. What is the power output in Watts?
Answer:
66 Watts
Step-by-step explanation:
Given data
Work= 3960Joules
Time= 60 seconds
We know that the expression for power is
Power= Work/TIme
Power= 3960/60
Power=66 Watts
Hence the power is 66 Watts

Od
560 ft3
Answer:
The volume of the shape is 560 ft^3
Step-by-step explanation:
To find the volume of the figure, we need to multiply the base area by the height of the figure
mathematically, we have the base area as a rectangular shape and its area is the product of its side lengths
We have this as 8 ft * 10 ft = 80 ft^2
So multiplying this by the height which is 7 ft, we have this as;
7 ft * 80 ft^2 = 560 ft^3

Answer:
y=11/3
Step-by-step explanation:
39 = 6(1) + 9y
39 = 6 + 9y
39 - 6 = 9y
33 = 9y
9y = 33/9
y = 11/3
Answer:
y = 11/3
Step-by-step explanation:
Sometimes it's just how things are written that makes them seem super hard.
R = 6x + 9y is the equation, and then they say what to sub in for x and R. So now we have:
39 = 6(1) + 9y
39 = 6 + 9y
subtract 6 from both sides
33 = 9y
y = 33/9, simplified to 11/3

breakfast costs $1.25. Which inequality
represents the relationship between the
number of breakfasts, b, he can buy and
the amount of money he has?
F 5 1.25 + b
G5 < 1.25 + b
H 5 > 1.25b
J 5 < 1.25b
Answer:
The answer would be letter J
The inequality for total expenditure & number of breakfasts is 5 > 1.25b
Formulation of inequality equation for expenditure & breakfasts
Assumed : Number of breakfasts = b
Number of breakfast meals x Price per breakfast meal = Total Expenditure
Total expenditure should be less or than equal to $1.25
So, 1.25b < 5
It implies that inequality : 5 > 1.25b

Some people use SOH - CAH - TOA to remember the trigonometric ratios for sine, cosine, and tangent. Why do you think that word might help?
Answer:
hope this is helpful
Step-by-step explanation:
SOH-CAH-TOA is really helpful in remembering what each of the ratios should look like.
For sine, SOH means --> Sine- Opposite- Hypotenuse
This helps to remember that when using sine, you should use the Opposite length over the Hypotenuse in your ratio.
For cosine, CAH means --> Cosine- Adjacent- Hypotenuse
Your ratio should have the Adjacent length over the Hypotenuse
For tan, TOA means --> Tangent- Opposite- Adjacent
Your ratio should have the Opposite length over the Adjacent length
what is the value of X in the diagram below
Answer:
18
Step-by-step explanation:
We will try to find the angle on the left side of the small triangle. So we have to use Tan.
SOHCAHTOA
TanФ = 12/8
[tex]Tan^{-1}[/tex] = 12/8 = 56.31°
So the other one is 33.69° It's the top left one of the smaller triangle.
The top right side of the bigger triangle is 56.31 because they both add up to make 90°
Now that we have an angle of the bigger triangle we will find the x.
Tan 56.31 = x/12
x = 18

First note that the triangles shown are isosceles triangles due to equality of two of their sides which is radius. So their baseline angles are equal
Since their middle angle are equal too, so their 3 angles are the same. It menas both triangles are similar.
However, we know two of three sides are equal, but the third should be also because of their similarity.
