Answer:
The wave's wavelength λ = 5 m
Step-by-step explanation:
Explanation:-
Given that the frequency f = 30HZ
Given that the velocity
'v ' = 150m/s
The wave's wavelength

C.
(280 + 7) ÷ (7 + 7)
D.

Answer:
(280+7) ÷ (7+7)
Step-by-step explanation:
hopefully this helps ya
The equation that is equal to 287 ÷ 7 is (280 + 7) ÷ (7 + 7). The correct option is C.
What is equation?An equation is a statement in mathematics that shows that two expressions are equal. It has two sides that are separated by an equal sign.
To find the value of 287 ÷ 7, we can use the following methods:
(280 ÷ 7) + (7 ÷ 7) = 40 + 1 = 41(280 ÷ 7) - (7 ÷ 7) = 40 - 1 = 39(280 + 7) ÷ (7 + 7) = 287 ÷ 14 = 20.5(280 ÷ 7) + (280 ÷ 7) = 40 + 40 = 80We can simplify 287 ÷ 7 as follows:
287 ÷ 7 = 280 ÷ 7 + 7 ÷ 7
Note that 7 ÷ 7 simplifies to 1, so we have:
287 ÷ 7 = 280 ÷ 7 + 1
Therefore, the answer is C. (280 + 7) ÷ (7 + 7) = 287 ÷ 14 = 20.5.

A painter is placing a ladder to reach the third story window, which is 14 feet above the ground and makes an angle with the ground at 70°
How far out from the base of the building does the ladder need to be positioned? Round your answer to the nearest tenth.
Answer:
4.8
Step-by-step explanation:
We are given the hypotunese or the slanted side which is the ladder length which is 14.
We are given an angle at the bottom which is 70 degrees.
We are asked to find the horizontal side which is adjacent to the angle at the bottom.
Since we have a hypotunese and a side adjacent to the angle, we are going to use the function cosine.
we use this formula
[tex] \cos(theta) = \frac{adj}{hypo} [/tex]
[tex] \cos(70) = \frac{x}{14} [/tex]

32) In a triangle, the exterior angle is twice of each of the interior remote angles. The exterior angle is 1200. Find the measure of the three angles of the triangle.
Answer:
60 degrees each
Step-by-step explanation:
For the triangle, the sum of the interior angles is equal to the exterior
Let x and y be interior
Let z be the third angle
w be the exterior
w = x+y
120 = x+y
If the exterior angle is twice of each of the interior remote angles, then;
2x = 2y
x = y
120 = x+x
2x = 120
x = 60
Since x = y, y = 60 degres
From the triangle, the third angle will be 180 - 120
z = 180-120
z = 60
The measures of the 3 angles are 60 degrees each
