Answer:
x<=119
Step-by-step explanation:
If it's no greater that the mean is 120 seconds, then the sum of the seconds should be 600. 600-118-129-120-114=119
So x should be less or equal to 119.

Charlotte measured the temperature at 7:00 A.M. and again at 3:00 P.M., She placed both measurements on a number line.
How did the temperature change between 7:00 A.M. and 3:00 P.M.?
A. It increased by 3/4 °C.
B. It decreased by 3/4°C.
C. It increased by 11 and 3/4 °C.
D. It decreased by 11 and 3/4 °C.
Answer:
I think its C. It increased by 11 and 3/4 °C.
Step-by-step explanation:
I say that because it increases by 10 (-5 from +5) then to 6 which makes it 11 times. Then, it increases by 3/4 since its 2/4 + 1/4 which gives u 3/4. Also, its an increase and not a decrease because the numbers on the number line is going pass 0, so that shows an increase.
Darla applies the commutative property to the product.
(1112)⋅(−17)⋅(24)
Which expression illustrates the commutative property applied to the product?
(1112)⋅[(−17)⋅(24)]
[(1112)⋅(−17)]⋅(24)
(1112)⋅(24)⋅(−17)
(1112)⋅(−17)⋅(24)
Answer:
C) (1112)*(24)*(-17)
Step-by-step explanation:
The commutative property states that AxB = BxA
A&B) The commutative property does not include regrouping. This falls under a different rule called the Associative property
C) This is the answer because it shows that even when numbers move around so long as the order of operations doesn't change nothing is wrong
D) This isn't correct because it is simply the restatement of the original question
The product of the given numbers is - 4,53,696. Therefore, option A and B are correct answer.
The given expression is 1112×(−17)×24.
What is the commutative property to the product?The commutative property deals with the arithmetic operations of addition and multiplication. It means that changing the order or position of two numbers while adding or multiplying them does not change the end result.
Now, (1112×(−17))×24
= - 18,904 × 24
= - 4,53,696
and 1112×((−17)×24)
= 1112× (-408)
= - 4,53,696
The product of the given numbers is - 4,53,696. Therefore, option A and B are correct answer.

How do you find the height of a rectangular prism with the volume and area?
Answer:
The volume of the prism is the area of the base times the height. So to calculate height, divide the volume of a prism by its base area. For this example, the volume of the prism is 500 and its base area is 50. Dividing 500 by 50 results in 10.

which expression has a value of 30 when x = -1 and y = 3?
Answer:
B. (x - 3²)(y-6)
Step-by-step explanation:
Find the expression with a value of 30;
when x = -1 and y = 3:
A. (x - 3²).y-6
(-1 - 9).3-6 = -10 x 3 -6 = -30 - 6 = -36
B. (x - 3²)(y-6)
( -1 -3²)(3 - 6) = (-1 -9)(-3) = 30
C. x - 3² . (y-6) = -1 - 9.(3-6)
= -1-9.-3
= -1 - 9 x -3
= -1 + 27
= 26
D. x - 3².y-6 = -1 - 9. 3 - 6
= -1 - 27 - 6

Write an expression to represent the perimeter of the figure below.
Step-by-step explanation:
A perimeter is when you add up all of the sides
Here would be our equation
[tex]2(x+4)+2(2x-8)[/tex]
Answer: The expression for this would be 2(x+4) + 2(2x-8)
Step-by-step explanation:
This is because when we calculate perimeter, we add up all the sides. So, instead of doing (x+4)+(x+4), we can just do 2(x+4) and add up all sides. So, here’s the answer in simplest form!
