X+6=3x we just learned how to do this math today I need help
Answers
Answer:
x=3
Step-by-step explanation:
Answer: x=3
Step-by-step explanation:
First, you need to subtract x and x by itself, and do the same with the 3x. Your equation should now look like 6 = 2x. Now, divide each side of the equation with 2, and now your equation should look like 3 = x!
-----------------------
So, to double check, replace the x's with 3. The equation should be 3 + 6 = 3(3). If you do the math, it equals 9 = 9!
Complete the following ratios: Current assets = $13,000 Inventory = $4,400 Current liabilities = $10,000 Net income = $7,700 Net sales = $24,400 A. Profit margin on net sales (round to nearest tenth percent) B. Acid test (round to nearest tenth percent.)
Answers
The completion of the following accounting ratios is as follows:
A. Profit margin on net sales is 31.6%.
B. Acid test is 86.0%.
What are accounting ratios?Accounting ratios enable financial analysts to understand the relative magnitude of one financial statement account to another.
By their nature, accounting ratios compare or represent an entity's financial performance or position in relative terms.
Current assets = $13,000
Inventory = $4,400
Current liabilities = $10,000
Net income = $7,700 Net sales = $24,400
The profit margin on net sales = Net Income ÷ Net Sales x 100
= $7,700 ÷ $24,400
= 31.6%
Acid Test Ratio = (Current Assets - Inventory) ÷ Current Liabilities
= ($13,000 - $4,400) ÷ $10,000
= 0.86
= 86%

What is compound interest?
The interest that is paid on both the initial principal and the accumulated past interest is known as compound interest.
The compound amount and compound interest are calculated by:
Compound amount, [tex]A=P(1+\frac{r}{n} )^{nt}[/tex]
Compound interest, [tex]I = A - P[/tex]
where, P is the principal amount
r is the rate of interest(in decimal)
n is the number of times the interest is compounded annually
t is the time.
Given, Principal amount, P = $1400
rate of interest, r = 2.5% = 0.025
n = 2 (compounded semi-annually)
t = 3 years
Then, the compound amount is calculated by:
[tex]A=1400(1+\frac{0.025}{2} )^{2*3}\\[/tex]
or, [tex]A=1400(1+0.0125 )^{6}\\[/tex]
or, [tex]A=1400(1.0125 )^{6}\\[/tex]

Part A: Use the Pythagorean Theorem to derive the standard equation of the circle, with center at (a, b) and a point on the circle at (x, y). Show all necessary math work.
Part B: If (a, b) = (5, –2) and c = 10, determine the domain and range of the circle.
Part C: Is the point (10, 2) inside the border of the circle if (a, b) = (5, –2) and c = 10? Explain using mathematical evidence.
Answers
The distance to the point is less than c=10, so the point is inside the circle.
Given that, (a, b) = (5, –2) and c = 10.
What is domain and range of the function?The domain and range are defined for a relation and they are the sets of all the x-coordinates and all the y-coordinates of ordered pairs respectively. For example, if the relation is, R = {(1, 2), (2, 2), (3, 3), (4, 3)}, then:
Domain = the set of all x-coordinates = {1, 2, 3, 4}
Range = the set of all y-coordinates = {2, 3}
Part A:
Use of the Pythagorean theorem gets you to the equation for a circle in essentially one step:
Sum of squares of sides = square of hypotenuse
(x -a)²+(y -b)² = c² circle centered on (a, b) with radius c.
Part B:
The circle will be defined for values of x in the domain f ± c, and for values of y in the range b ± c.
domain: 5 ± 10 = [5, -5]
Range: -2 ±10 = [8, -11]
Part C:
The distance from point (10, 2) to (a, b)=(5, -2) is
c² = (10-5)² +(-2-2)²
c² = 25+16
c² = 41
c=√41
c=6.4
The distance to the point is less than c=10, so the point is inside the circle.
Therefore, the distance to the point is less than c=10, so the point is inside the circle.

If the sales tax rate is 5% in Texas, then how much sales tax would you pay in Houston for a $52 bag of dog food?
Please answer quickly!
Thank you ^^
Answers
The cost of the sales tax in Houston is $ 2.60 and the total cost of bag of dog food is $ 54.60
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
The sales tax percentage in Texas = 5 %
= 5 / 100
= 0.05
The cost of 1 bag of dog food in Houston = $ 52
Now ,
The sales tax cost is calculated by the equation ,
The sales tax cost =
Sales tax percentage in Texas x cost of 1 bag of dog food in Houston
The sales tax cost = $ 52 x 0.05
= $ 2.60
And , the total cost of 1 bag of dog food = cost of 1 bag of dog food in Houston + sales tax cost
Total cost of 1 bag of dog food = $ 52 + $ 2.60
= $ 54.60
Therefore , the sales tax cost is $ 2.60
Hence , the sales tax cost to pay in Houston is $ 2.60 and the total cost of bag of dog food is $ 54.60

The retail price of a golf club is $342. If the golf store has marked up the price by $42, what is the markup rate?
Answers
A golf club costs $342 at retail. The markup rate is 71.4% if the golf store has increased the price by $42.
What is meant by markup rate?The markup percentage is the difference between what an item costs the seller and what the customer pays. The greater the markup, expressed as a percentage of the cost, the greater the profit. While there is no "ideal" markup percentage, most businesses set it at 50%. A 50 percent markup, also known as a "keystone," means you are charging a price that is 50% higher than the cost of the good or service. Both terms are used to help determine profitability, but they are not the same! The markup is the percentage difference between a product's selling price and its cost.Given,
The difference in prices is $342 - $42 = $300
So, we need to find what percentage of 42 is 300
We do this by dividing: 300/42 = 7.14
which is 71.4 %.
So, the markup is 71.4 %.

Round off
Round off refers a number is made simpler by keeping its value intact but closer to the next number. And it is done for whole numbers, and for decimals at various places of hundreds, tens, tenths, etc.
Given,
Here we need to estimate 6769 x 925 by first rounding each number so that it has only 1 nonzero digit.
Here we have to take individual terms to round off then we get,
By rounding 6799 so that it has only one non-zero digit is rounding it to nearest thousand.
6769 rounds to nearest thousand as 7000 as hundreds digit 7 > 5.
Similarly, by rounding 925 so that it has only one non-zero digit is rounding it to nearest hundred.
925 rounds to nearest hundred as 900 as tens digit 2 < 5.
Now, the estimated value after rounding each number so that it has only one non-zero digit is

If a runner traveled a distance of d(h)=/16h4 in time t(h) = 3h4 - 3h3 -5h2 what is the runner's speed?
Answers
The runner's speed If a runner traveled a distance of d(h)=/16h4 in time t(h) = 3h^4 - 3h^3 -5h^2 is 4 /3h^2 - 3h -5h.
How can the speed be calculated?The concept that will be used to calculate this is the concept of speed which is the ratio of the distance per time which can be expressed as
speed = distance/time
Then we were given distance as d(h)=/16h^4
time as t(h) = 3h^4 - 3h^3 -5h^2
Speed = [tex]\sqrt{16h^4} /3h^4 - 3h^3 -5h^2[/tex]
Then we will have 4h^2 /3h^4 - 3h^3 -5h^2
then take h^2 from both the numerator and denominator and then cancel them , then we will have
= 4 /3h^2 - 3h -5h.
