Please i really need help! i need a full explanation
Answer:
Conduction is the transfer of thermal energy through direct contact between particles of of a substance, without moving the particles to a new location. Conduction usually occurs in solids. Convection is the transfer of thermal energy through movement of particles from one location to another. Convection usually occurs in liquids. Radiation is the emission of energy as waves or particles or rays. Radiant energy is either reflected or absorbed by matter. Convection causes things like the rain cycle and radiation comes from things like the sun.

78 - 2x = 89 - 3x
Add 3x to both sides
78 - 2x + 3x = 89
78 + x = 89
Subtract 78 from both sides
x = 89 - 78
x = 11

If Xavier rolls a number cube 90 times, how many times can he expect it to land on a number greater than 4? *
Answer:
30
Step-by-step explanation:
There are 6 possible outcomes when rolling a number cube, and each outcome is equally likely.
What is probability?Probability is simply the likelihood of something occurring. When we are uncertain about the outcome of an event.
There are 6 possible outcomes when rolling a number cube, and each outcome is equally likely.
Since we are interested in the number of times the cube lands on a number greater than 4, we only need to consider the outcomes 5 and 6.
The probability of rolling a 5 or a 6 on one roll of the cube is 2/6, or 1/3. Therefore, we can expect Xavier to roll a number greater than 4 about 1/3 of the time.
To find out how many times he can expect it to happen in 90 rolls, we can multiply the probability by the number of trials:
Expected number of rolls with a number greater than 4 = (1/3) x 90 = 30
Therefore, Xavier can expect the cube to land on a number greater than 4 about 30 times out of 90 rolls.

x 1 1 (This is a right triangle)
1 69° 1
1-------------1
11
1. first identify a trigonometric ratio that will make it possible to find the value of x.
Answer = X is opposite to the angle 69° and 11 is adjacent to the angle 69°
2. To find the unknown value, which trigonometric function should be used?
Answer = Tangent
3. Use the tangent ratio for TAN 69°.
Answer = TAN 69° = [tex]\frac{x}{11}[/tex]
4. Multiply both sides by 11.
TAN 69° = [tex]\frac{x}{11}[/tex]
Answer = 11 · TAN 69° = x
5. Simplify
11 · TAN 69° = x
11(2.6051) ≈ x
(Blank) ≈ x
Answer = 28.7 ≈ x < -- (Rounded to the nearest tenth)
11(2.6051) ≈ x This is the part I'm having trouble with. I don't understand how to get the decimal in the parenthesis. I've tried dividing, multiplying, multiplying and then dividing. I just can't get the correct answer. I think I'm suppose to use a geometry calculator and input TAN then multiply(or divide I don't know), but I don't have one right now so I need to know if there's any way I could get the same answer with a regular calculator.

Nineteen less than 6 times a number is the same as 16 more than the number. The equation is The solution is x -7 7.
Answer:
The number is 7
Step-by-step explanation:
let the said number be x
Nineteeen less than 6 times a number;
6x - 19
equals; 16 more than the number; this is 16 + x
Thus;
6x - 19 = 16 + x
6x-x = 16 + 19
5x = 35
x = 35/5
x = 7

Step-by-step explanation:
If a bowling ball is dropped out of an airplane,
what will its speed (velocity) be after 3.4
seconds, assuming no air resistance? (Hint: Use
the equation v = 32t).
Answer: The velocity of the ball is 108.8 ft/s downwards.
Step-by-step explanation:
When the ball is dropped, the only force acting on the ball will be the gravitational force. Then the acceleration of the ball will be the gravitational acceleration, that is something like:
g = 32 ft/s^2
To get the velocity equation we need to integrate over time, to get:
v(t) = (32ft/s^2)*t + v0
where v0 is the initial velocity of the ball. (t = 0s is when the ball is dropped)
Because it is dropped, the initial velocity is equal to zero, then we get:
v(t) = (32ft/s^2)*t
Which is the same equation that we can see in the hint.
Now we want to find the velocity 3.4 seconds after the ball is dropped, then we just replace t by 3.4s, then we get:
v(3.4s) = (32ft/s^2)*3.4s = 108.8 ft/s
The velocity of the ball is 108.8 ft/s downwards.
