Thomas earns $2100 per month and then got a 15 raise .how much will Thomas make per month after his raise
Final answer:
Thomas will earn $2415 per month after a 15% raise on his current salary of $2100, which results in a raise amount of $315.
Explanation:
Thomas currently earns $2100, and with a 15% raise, we need to calculate the increase in his monthly pay. To find the amount of the raise, we calculate 15% of his current earnings. That is, we multiply his earnings by the raise percentage expressed in decimal form: $2100 × 0.15 = $315.
After finding the raise amount, we add it to his current salary to find his new monthly earnings. $2100 + $315 = $2415 per month. Therefore, after a 15% raise, Thomas will make $2415 per month.

Use the sequence below to answer parts a and b (8,17,26,35,44,53,...) Create an explicit formula to determine the 12th term of the sequence Create a recursive formula to prove the 7th term is 62.
The explicit formula for the sequence (8, 17, 26, 35, 44, 53, ...) is 8 + (n-1) * 9, and the 12th term can be found by substituting n = 12. The recursive formula for the sequence is a1 = 8 and an = an-1 + 9. Using this recursive formula, we can verify that the 7th term is indeed 62.
Explanation:To create an explicit formula for the sequence (8, 17, 26, 35, 44, 53, ...), we notice that the difference between each term is 9. So, the explicit formula for the sequence is 8 + (n-1) * 9, where n represents the position of the term in the sequence. Using this formula, we can find the 12th term by substituting n = 12: 8 + (12-1) * 9 = 89.
To create a recursive formula to prove that the 7th term is 62, we observe that each term is the previous term plus 9. So, the recursive formula for the sequence is:
a1 = 8an = an-1 + 9Using this recursive formula and starting with a1 = 8, we can find the 7th term as follows:
a1 = 8a2 = a1 + 9 = 8 + 9 = 17a3 = a2 + 9 = 17 + 9 = 26a4 = a3 + 9 = 26 + 9 = 35a5 = a4 + 9 = 35 + 9 = 44a6 = a5 + 9 = 44 + 9 = 53a7 = a6 + 9 = 53 + 9 = 62Therefore, the 7th term in the sequence is indeed 62.

If there are 1000 grams in a kilogram and 454 grams in a pound, how many pounds are there per kilogram?
Answer:2.2 pounds per kilogram
Step-by-step explanation:
454gram = 1 pound
since; 1000g = 1kg
454g = x
x= 454/1000
x=0.454kg
there is 0.454kg in 1 pound
but the question says how many pound is in 1kg
0.454kg = 1 pound
1 kg = x
cross multiply
0.454x = 1
Divide bothside by 0.454
x = 1/0.454
x = 2.2 pound
Therefore; there are 2.2pounds in 1 kilogram.
There are 2.20 pounds are there per kilogram
Given that,
1 kg = 1000 gm
1 pound = 454 gm
Since we know that,
A measurement unit is a standard quality used to express a physical quantity. Also it refers to the comparison between the unknown quantity with the known quantity.
Since,
1 pound = 454 gm
Therefore,
⇒ 454 gm = 1 pound
⇒ 1 gm = 1/454 pound
And since,
1 kg = 1000 gm
= 1000x(1/454) pound
= 2.20 pounds
Hence,
1 kg = 2.20 pounds

The difference between three-fifths of a number and 7 is -36
The value of a number such that The difference between three-fifths of that number and 7 is -36 is -145/3.
What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Summation = addition of two or more numbers or variable
Subtraction = Minus of any two or more numbers with each other called subtraction.
Let's say that number is x.
Three-fifth of x ⇒ (3/5)x
The difference of (3/5)x and 7 will be,
(3/5)x - 7 = -36
Add 7 on both sides
(3/5)x = -29
Multiply 5/3 on both sides
x = -29(5/3)
x = -145/3
Hence "The value of a number such that The difference between three-fifths of that number and 7 is -36 is -145/3".

If the equatorial diameter of the sun is 1.39 million km how many kilometers is the sun's radius
A trough is 12 ft long and its ends have the shape of isosceles triangles that are 5 ft across at the top and have a height of 1 ft. If the trough is being filled with water at a rate of 13 ft3/min, how fast is the water level rising when the water is 8 inches deep?
I have been getting 13/30, but apparently, that is wrong?
V=.5 * h * l * b
Because of similar triangles:
b = 5h (b/h = 5/1)
l = 12
V = .5 * h * 5h * 12
V = 30h^2
(dV/dt) = 60 h (dh/dt)
dV/dt = 13
h = .5 (because this is in feet)
13 = 60*.5(dh/dt)
13/30 = dh/dt
The rate at which the water level is rising when the water is 8 inches deep in the trough is 13/30 ft/min.
Explanation:To find how fast the water level rises when the water is 8 inches deep, we need to use the equation V = 30h^2, which represents the volume of the trough as a function of its height h. We are given that the trough is being filled at a rate of 13 ft^3/min, so we can set dV/dt (the rate of change of volume) equal to 13.
Substituting the given values into the equation dV/dt = 60h * dh/dt, we get 13 = 60 * h * dh/dt. Since h = 0.5 (in feet), we can solve for dh/dt which turns out to be 13/30 ft/min.
Therefore, the water level is rising at a rate of 13/30 ft/min when the water is 8 inches deep.

Answer: The slope (m) of the line using two points where the line goes through is:
m = - 4 (negative 4).
Solution:
m=(y2-y1) / (x2-x1)
Taking two points in the graph where the line goes through:
P1=(0,2)=(x1,y1)→x1=0, y1=2
P2=(1,-2)=(x2,y2)→x2=1, y2=-2
