Answer:
61.4°
Step-by-step explanation
Given
Length of the ramp = 23ft = hypotenuse
Base of the ramp = 11ft = Adjacent
Required
Angle of elevation x
Using the SOH CAH TOA identity
Cos theta =adj/hyp
Cos x = 11/23
Cos x = 0.4782
x = arccos0.4782
x = 61.42°
Hence the angle of elevation is 61.4°

How fast must Larry travel to go 678 mi. in 12 hrs?
Answer:
8136
Step-by-step explanation:
Answer:
Larry must travel at a speed of 56.5mi / h.
Step-by-step explanation:
If the question is asking us how fast must Larry travel we are asking about his speed. The speed is equal to distance divided by time, therefor Larry must travel with the following speed.
Speed = Distance/ Time
Speed = 678mi / 12hrs
Speed = 56.5mi / h

3. A landscape plan includes a rectangular flower bed that is surrounded the wood planks. In the drawing, the rectangular flower bed is 8 in. by 12 in. The length and width of the actual flower bed will be 26 times larger than the length and width in the drawing.
(a) What is the perimeter of the drawing? Show all calculations that lead to the answer and include units.
(b) What is the perimeter of the actual flower bed? Show all calculations that lead to the answer and include units.
(c) What is the effect on the perimeter of the flower bed with the dimensions are multiplied by 26? Write the final answer in a sentence and show supporting calculations to arrive at the answer.
Answer:I dont know if this is right but
A: 384 in.
B: 1040 in. = 86 ft
C: because the dimensions are multiplied by 26 inches, the perimeter for the actual flower bed is converted into feet.
Step-by-step explanation:
A: (8*2)+(12*2) = 384 in.
B: ((8*26)*2)+((12*26)*2) = 1040 in. = 86 ft.

40in = 3ft 4in
(B) 8 x 26= 208
12 x 26= 312
(208 x 2) + (312 x 2) = 1040in = 86ft

that's my question I dont get please help
Answer:
I would assume that there is more to this question somewhere on the paper. w seems to be the variable you have to find. Check if you have any more info near that question that would help you find the value of w, so that you can find out what 29 to the power of w is.
There should be an equation somewhere to solve for the value of w.
If that is the only information provided for that question, then it seems like a typo, I guess.

Write - 1.5y = 4.5x - 9 in standard form .
The standard from of the equation - 1.5y = 4.5x - 9 is 3x + y = 6.
What is an equation?A mathematical equation is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.
Given equation is - 1.5y = 4.5x - 9. The standard form of an equation is given as:-
ax + by = c
Reduce the equation -1.5y = 4.5x - 9 in standard form:-
-1.5y = 4.5x - 9
4.5x + 1.5y = 9
3x + y = 6
Therefore, the standard from of the equation - 1.5y = 4.5x - 9 is 3x + y = 6.
