Answer:
1. Consider a hot pot taken off the stove and placed on a tile countertop. At first it cools quickly. As it cools, the difference in temperature between the pot and the room air becomes less, and so it takes a long time for the pot to lose enough heat to match room temperature. Two objects at the same temperature are said to be in equilibrium.
2. When a liquid changes into a gas it absorbs energy. When it changes into a solid it gives off energy...If a solid (dry ice for example) is allowed to sublimate into a gas, it absorbs heat - that's why it feels cold when you touch ice. So, if a gas changes into a liquid, it give off heat as an opposite effect. Anytime you compress a gas, it gets warmer.

Pls hurry
Answer:
x = 10
Step-by-step explanation:
[tex]6^{2} + 8^2 = x ^2[/tex]
Solve for x and you get x = 10
Answer:
x=14
Step-by-step explanation:
I can simplify the math terms ;)
So basically 6 and 8 are the lengths of the shorter sides of the triangle, the triangle has three sides and the longest side is always called the hypotenuse, the hypotenuse is the sum of the lengths of the shorter sides. So 6+8=x
6+8=14 <-- That's your answer :)

Answer:
(4b-5)^2
Step-by-step explanation:
I am assuming it's asking this? I'm not too sure.
Answer:
[tex](4b - 5 {)}^{2} [/tex]
Step-by-step explanation:
1) Rewrite it in the form a² - 2ab + b², where a = 4b and b=5.
[tex](4b)^{2} - 2(4b)(5) + {5}^{2} [/tex]
2) Use square of Difference: (a - b)² = a² - 2ab + b².
[tex](4b - 5)^{2} [/tex]
Therefor, the answer is ( 4b - 5)².

Find the height of an equilateral triangle whose perimeter is 24
Answer:
[tex]h = 4\sqrt{3}[/tex]
Step-by-step explanation:
If the triangle is equilateral, it means that all the sides are the same. Since there are 3 sides in a triangle, each side is 24/3 = 8
Now, in order to find the height, we can use the pythagoeren theroem. Notice that the height bisects(splits the side) into two equal parts, which each part having the length 8/2 = 4
So we have [tex]h^2 + 4^2 = 8^2[/tex]
[tex]h^2 = 48[/tex]
[tex]h = 4\sqrt{3}[/tex]

each day for the first four days from the list of students who have not already gone.
What is the probability you will be chosen to go on the first day? State the answer as
a fraction.
Answer:
4/21
Step-by-step explanation:
since we are only talking about the first day, there are still 21 options for your teachers. there are 4 spots that you can fill, so the probability that you will be picked is 4/21
The probability you will be chosen to go on the first day would be; 4/21
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
We are given that there are 21 students in your class. The teacher wants to send 4 students to the library each day.
Since we are only talking about the first day, there are still 21 options for your teachers.

Factorise, check by using multiplication a-7a+12
Answer:
Step-by-step explanation:
Sum = -7
Product = 12
Factors = (-3) ; (-4) { (-3) * (-4) = 12 and (-3) + (-4) = -7}
a² - 7a + 12 = a² -3a - 4a + (-3)(-4)
= a(a - 3) - 4(a - 3)

I need the correct answer
Answer:
56.7
Step-by-step explanation:
Hello There!
Trigonometric Ratios
sin = opposite divided by hypotenuse
cos = adjacent divided by hypotenuse
tan = opposite divided by adjacent
we need to find x and we are given its opposite side length and the hypotenuse
so the trigonometric ratio we need to use is sin
knowing that sin = opposite side divided by hypotenuse we create an equation
[tex]sin(x)=\frac{51}{61}\\\frac{51}{61} = .8360655738\\arcsin(sinX)=x\\arcsin(.8360655738)=56.72695659[/tex]
our final step is to round to the nearest tenth of a degree
so we can conclude that the measure of angle A is 56.7
note: arcsin = inverse of sin
Answer:
56.7
Step-by-step explanation:
so opposite the angle we are working out is "o"And the longest side is the hypotunese but just remember it as "h"a is the remaining side but does not have a value and is blank therefore we need to worry about this sideWe have "o" and "h" which is the formula triangle with sin o/sin*hBut as we are working out the angle(sin) we change the formula so it is sin=0/hsin=51/61sin=0.8then you click the shift or 2nd function button on your calculator and the sin button and this is your answer 56.7so the angle is 56.76.

What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
We have to use the two points (2, 50) (6, 150) shown to find the number of soda bottles the machine can make per minute.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
x₁=2, y₁=50, x₂=6, y₂=150
substitute in slope formula
Number of soda bottles=slope=150-50/6-2
=100/4
=25
Hence 25 soda bottles the machine can make per minute.
