A! hope this helps ( f(x)=2) )
Step-by-step explanation:
The given problem is : −4.5 + 4.2 + 5.6 − 7.3
The order for solving an arithmetic problem is as follows :
- Parentheses,
- Exponentiation,
- Multiplication,
- Addition,
- Subtraction,
We can rewrite the given problem as : 4.2 + 5.6 - 7.3 - 4.5
Taking 4.2 and 5.6 together in bracket : (4.2 + 5.6) - 7.3 - 4.5
= 9.8 - 7.3 - 4.5
= 2.5 - 4.5
= -2
Hence, the answer for given problem is -2, but Andrew get -21.6 which is wrong.
The 3 inside angles of a triangle need to equal 180 degrees.
This is a right triangle so the bottom left corner is 90 degrees.
This means the other two angles when added need to equal 180-90 = 90 degrees.
Now you have 8x + 7x = 90
Combine like terms:
15x = 90
Divide both sides by 15
X = 6
Now you have the value for x solve the two angles:
8x = 8(6) = 48
7x = 7(6) = 42
Top left = 48 degrees
Bottom right = 42 degrees
Answer:
24501.42 cubic meters
Step-by-step explanation:
Volume of a cylinder
= pi r^2 h
Given diameter = 34
radius r = diameter/2
= 34/2 = 17
So radius r = 17
Height h = 27
Pi = 3.14
Volume = 3.14 x (17)^2 x 27
= 3.14 x 17 x17 x 27
Multiply through
= 24501.42 cubic meters
