Answer:
P = (21.4a+36.6) cm
Step-by-step explanation:
Given that,
The width of a rectangle, b = (6.9a+8.5) cm
The length of a rectangle, l = (3.8a+9.8) cm
We need to find the perimeter of the rectangle. Perimeter is the sum of all sides. So,
P = 2(l+b)
Put all the values,
P = 2(6.9a+8.5+3.8a+9.8)
= 2(6.9a+3.8a+8.5+9.8)
= 2(10.7
a+18.3)
= (21.4a+36.6)
So, the perimeter of the rectangle is (21.4a+36.6) cm.
Answer:
scale factor of 4
Step-by-step explanation:
3 times 4 equals 12
-4 times 4 equals -16
The 3 angles of a triangle have to add up to 180 degrees. Since we are given 2 of the angles, all we have to do is add them up and then subtract from 180 to get the 3rd.
112 + 41 = 153
180 - 153 = 27
Angle 2 = 27 degrees.
Answer:
The distance of the object from the base of cliff is 18.24 meters
Step-by-step explanation:
Given as :
The height of the vertical cliff = h = 50 meters
The distance of the object from the base of cliff = x meters
Let The angle of depression of object that level with cliff base = Ф = 70°
<u>Now, from figure</u>
Tan angle = 
I.e TanФ = 
Or, TanФ = 
Or, Tan 70° = 
Or, 2.74 = 
∴ x = 
I,e x = 18.24 meters
So, The distance of the object from the base of cliff = x = 18.24 meters
Hence,The distance of the object from the base of cliff is 18.24 meters Answer
<u>Answer:</u>
The correct answer option is A. Loss of 9 oz.
<u>Step-by-step explanation:</u>
We are given that a cat's weight change -8 oz. while she was sick. It means that the cat lost 8 ounces of weight.
