Answer:
-78.85
Step-by-step explanation:
Using Order of Operations (PEDMAS):
23.15 – [ 115 + ( 12 - 25)]
= 23.15 – [ 115 + (-13)]
= 23.15 – [ 115 - 13]
= 23.15 - 102
= -78.85
Answer:
The expression of h as function of x is h =
Step-by-step explanation:
Given as :
The distance of blimp (AB) = 5500 feet
The slanted distance to the pagoda (BC) = d feet
The horizontal distance (AC) = h
Let the angle made between slanted distance and horizontal distance be Ф
So , cos Ф = =
And sin Ф = =
∵, cos²Ф = 1 - sin²Ф
So, =
Or, =
Or, h² = d² - 5500²
∴ h =
Or, h =
Hence The expression of h as function of x is h = Answer

13 ft ▪️ square
What would be the surface area of a 13ft square
SURFACE AREA:
Answer: multiply by the number of faces
Step-by-step explanation:
If it is a square then you would do 13 x 13 = 169, that is the amount for one face. Then, multiply 169 times how many faces there are to find the surface area.
