Answer:
27 numbers are available.
Step-by-step explanation:
Multiply 3 by 3, 3 times so 3 × 3 × 3 = ?
or 3 to the third power
so 3 × 3 = 9
9 × 3 = 27
Answer: 6.67
Step-by-step explanation:
Using the similarity theory, we get the equation
5/30 = BM/40
BM = 5*40/30 = 20/3 = 6.67
Answer number 2
The formula for the area of a rectangle is (length x width)
so, 9 x ? = 36 which can also be written as 36 ÷ 9 = ?
and (36 ÷ 9 = 4)
Length x Width = Area
9 cm x 4 cm = 36 cm²
Answer:
Answer:C = 8
Answer:C = 8Step-by-step explanation:
-2(4c+16)^1/4+2=-2
Move the constant to the right and change the sign
-2(4c+16)^1/4= -2-2
transform expression
![- 2 \sqrt[4]{4c - 16} = - 4](https://tex.z-dn.net/?f=%20-%202%20%20%5Csqrt%5B4%5D%7B4c%20-%2016%7D%20%20%3D%20%20-%204)
Divide each side by -2
![\sqrt[4]{4c - 16 } = 2](https://tex.z-dn.net/?f=%20%5Csqrt%5B4%5D%7B4c%20-%2016%20%7D%20%20%3D%202)
raise both side of the equation by power of 4
4c-16=16
move constant to the right and change the sign
4c=16+16
4c=32
THEN DIVIDE BOTH SIDES BY 4
C = 8
Answer:
289feet²
Step-by-step explanation:
Area of a rectangle = length x breadth
area of a square = length²
area of the yard that is not covered by the hot tub and fire pit =
Area of the yard - (area of the hot tub + area of the fire pit)
Area of the yard = 20 feet² = 400 feet²
area of the hot tub = 6 feet² x 8 feet² = 48 feet²
area of the fire pit = 7 feet² x 9 feet² = 63 feet²
400 - (48 + 63) = 289 feet²
