Answer:
10.36
Step-by-step explanation:
So your solution would be:








Just try to remember PEMDAS.
Parenthesis, Exponent, Multiplication/Division, Addition/Subtraction.
This is the order we follow when going about expressions with many operations.
Let's start with the parenthesis part. Notice that there is an exponent beside the parenthesis enclosing the fraction. Here we use the quotient to a power rule. We distribute the exponent to the numerator and the denominator.



Now that we got the parenthesis and exponent out of the way, let's move on to the next. Multiplication/Division. Whichever comes first, you do it first.
We have a fraction so we do that first. Then we do the multiplication after.


Next we do the addition/subtraction. Again, whichever comes first.


4(x+7) becomes 4x+28 you multipli the 4 in parentheses ans 2(x+7) becomes 2x+14
4x+28=2x+14 you move the x termes to the left and other numbers to the right look:
4x-2x=14-28 when you change the sides always change the sign +or-
2x=-14
2x/2=-14/2
X=-7
Answer:
Group 2
Step-by-step explanation:
Because in group 2 they have more 46 year old tourists so it is most likely that the random 46 year old belongs to group 2.
Answer:
d = 520 cm^3 e = 1717.66 cm^2
Step-by-step explanation:
d) The area of the face triangle is 40 and multiply that with the length, 13 to get 520.
e) The volume of the half circle is 190.85 and the volume of the cone is 1526.81 and add them
