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.
The total change in the outdoor temperature over 6 hours was -21°F
What was the mean change in temperature per hour?
₋₋₋₋₋₋₋₋ °F per hour
Answer:
-3.5
Step-by-step explanation:
As there was a total change of -21, that would be the first part of your equation:
-21
As 6 hours had passed and you are trying to find the mean, your equation would now be:
-21 ÷ 6 = ?
Now you can solve the equation, and the answer is -3.5°F per hour.
The mean change in temperature per hour is -3.5 °F.
what is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
The total change in the outdoor temperature over 6 hours was -21°F
So, in one hour the mean change in temperature
= -21/6
= -3.5 °F
Hence, the mean change in temperature per hour is -3.5 °F.

−5.6x=−4
What is the solution to the equation?
Enter your answer as a simplified fraction in the box.
Answer: 0.714285
Step-by-step explanation:
The solution of the equation (-5.6 = -4) is (x = 5/7) and this can be determined by using the arithmetic operations.
Given :
-5.6x = -4
The following steps can be used in order to determine the solution to the equation (-5.6x = -4):
Step 1 - The arithmetic operations can be used in order to determine the solution to the given equation.
Step 2 - Write the given equation.
-5.6x = -4
Step 3 - Add 4 on both sides in the above equation.
-5.6x + 4 = -4 + 4
-5.6x + 4 = 0
Step 4 - Add 5.6x on both sides in the above expression.
-5.6x + 4 + 5.6x = 5.6x
4 = 5.6x
Step 5 - Divide 4 by 5.6 in the above expression.
[tex]x = \dfrac{4}{5.6}[/tex]
Step 6 - Simplify the above expression.
[tex]x = \dfrac{5}{7}[/tex]

The school band has a goal of raising $800 for some new uniforms. If they have raised $512 so far, what percent of their goal have they raised?
Answer: 64%
Step-by-step explanation:
The band needs $800 for new uniforms and of that, they only raised $512.
Set up a proportion [tex]\frac{part}{total} = \frac{percentage}{100}[/tex]and plug everything you know in.
[tex]\frac{512}{800}[/tex] = [tex]\frac{x}{100}[/tex]
Solve for x by cross multiplying and dividing.
512 × 100 = 51200
51200 ÷ 800 = 64
x = 64
The school band has raised 64% of their goal already.
Answer:
The Answer would be 64%

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!

Todd and his friends are painting 5 equal sections of a wall. The wall is 10 feet tall, but its length is unknown.
Each section will be a different color, so they need to know the area of each section.
so , i said 5/10x area = length * width A=10*x a= 10x
then i said you should divide , next i said 10x/5 10x in five sections is 2 in each q1 said area 10*x but x=2 so 10*2=20 is this correct?

I plugged all of the equations in to a coordinate plane
What is the slope of the line, y=5−4x?
Answer:
(m) =
ΔY
ΔX
= 0
Step-by-step explanation:
Answer:
the slope is -4
Step-by-step explanation:
You are given the equation y=5-4x. You can put that into slope intercept form. Slope intercept form is y=mx+b where b is the y intercept and m is the slope. In this equation the slope is -4 and the y intercept is 5. You can rearrange this equation into slope intercept form. If you do this you will get y=-4x+5.
