Answer:
Molecules in both the metal and the surrounding air will start moving at lower speeds?
Step-by-step explanation:
I'm not sure this is the right answer, because i thought that the air and the metal would be in equilibrium.
So sorry if this is wrong, chemistry isn't my strongest subject.
Answer:
The air molecules that are surrounding the metal will speed up, and the molecules in the metal will slow down.

Which is a reasonable first step that can be used to solve the equation 2(x + 6) = 3(x - 4) + 5?
Combine like terms, 3 and 5, on the right side of the equation.
Distribute 2 to x on the left side of the equation and 3 to x on the right of the equation.
Distribute 2 to (x + 6) and 3 to (X - 4)
Apply the subtraction property of equality to move the 6 from the left side of the equation to the right side.
Answer:
Distribute 2 to (x+6) and 3 to (x-4)
Step-by-step explanation:
The first thing you need to do when solving an equation with parenthesis is to always simplify the expression first before solving. This makes it easier to solve the equation.

Answer:
7.
Step-by-step explanation:
In order to find the range, you need to:
1. Arrange the set of numbers in order from smallest to largest.
2. Identify the smallest and largest numbers in the set.
3. Subtract the smallest number from the largest.

Step-by-step explanation:
Lexi runs a race at school. She runs at a rate of 4 miles per hour for the first mile, then increases her rate to 5 miles per hour until the last mile when she runs 6 miles per hour. Which equation below represents her time, T. In hours, If she runs a total of x miles
Answer:
60T = 12x - 1
Step-by-step explanation:
In speed distance and time, time(t) is given by
time = distance(d)/speed(s)
total distance ran = x miles
case 1
d = 1 mile
speed = 4 miles per hour
as time = distance(d)/speed(s)
t = 1/4
____________________________
case 2
speed = 5 miles per hour
it is given that out of x miles for first mile and last mile her speed was 5 miles per hour
thus distance for this speed can be calculated by
subtracting first and last mile from x miles
therefore
distance = x-2 miles\
t = (x-2)/5
_____________________________________
case 3
distance = 1 mile
speed = 6 miles per hour
t = 1/6
______________________________
Total time T as required will be sum of time for the 3 case calculated above
T = 1/4 + (x-2)/5 + 1/6
T = 1/4 + (x - 2)/5 + 1/6 (taking LCM of 6,5,4 as 60 and solving)
T = (15 + 12x - 24 + 10)/60
T = (12x - 1)/60
60T = 12x - 1
Thus, equation 60T = 12x - 1 represents her time T

A circle has a radius of square root 131 units and is centered at (0,-4.3).
Whats the equation of this circle?
Answer:
x^2 + (y + 4.3)^2 = 131
Step-by-step explanation:
The basic equation of a circle with center at (h, k) and radius r is
(x - h)^2 + (y - k)^2 = r^2. Here the center is (0, -4.3) and the radius is √131. Substituting as indicated, we get:
(x - 0)^2 + (y + 4.3)^2 = 131, or
x^2 + (y + 4.3)^2 = 131

237.15/0.45 = 527
Answer:
They sold 527 toys.
Step-by-step explanation:
If they make 0.45$ profit on every toy.
Total profit of a month is $237.15.
then no of toys sold = total profit divided by individual profit
Number of toys= 237.15/0.45 =527

Jeremy’s dad is making cupcakes for his birthday. He needs 50 cupcakes in all. So far he made 13 chocolate cupcakes and 15 vanilla cupcakes. How many more cupcakes must he make?
Answer:
22 cupcakes
Step-by-step explanation:
13+15=28
50-28=22
Answer:
22 cupcakes
Step-by-step explanation:
First, let's find how many cupcakes he has already made.
He made 13 chocolate and 15 vanilla. If we add them together, we can find how many he has made total.
13+15=28
So far, he has 28 cupcakes.
He needs 50 cupcakes, and he has already made 28. The difference of the two numbers will be how many he must still make.
Subtract 28 from 50
50-28=22
So, he still has to make 22 cupcakes
