Answer:
Step-by-step explanation:
The marked price is 39.98
The tax is 4.5%
That means that the tax is added on to the marked price to get the selling price.
One way to do is is to multiply by the tax factor.
The tax factor is 1 + 4.5/100 = 1.045
So the Selling price = 39.98 * 1.045
Selling price = 41.78 rounded to 2 decimal places.
The more standard way of doing this is to multiply the tax by the marked price and add that on to the marked price to get the selling price.
39.98 * 4.5/100 = 1.7991
39.98
1.7991 Add
41.7791
The difference comes in where you do the rounding. The second way to do this has no rounding. If you convert this to money, the answer will be 41.78, just as the first way's answer.

Step-by-step explanation:
True or False: If one of the legs in a right triangle is half of the hypotenuse, then the angle opposite to that leg is 60 degrees.
We want to see if the given statement is true or false.
We will prove that the statement is false.
The statement is:
" If one of the legs in a right triangle is half of the hypotenuse, then the angle opposite to that leg is 60 degrees."
We can use the rule:
Sin(θ) = (opposite cathetus)/(hypotenuse).
Let's define:
hypotenuse = H
opposite cathetus = H/2
Let's see if the given angle is equal to 60°, we will have:
Sin(θ) = (H/2)/H = 1/2
θ = Asin(1/2) = 30°
So we can see that the statement is false.

Drag expressions to show the steps to create an equivalent expression using only positive exponents. Let g and h be two nonzero numbers. g^-3h
Equivalent expressions are expressions that have the same value.
The equivalent expression of [tex]g^{-3}h[/tex] is: [tex]\frac{h}{g^3}[/tex]
The expression is given as;
[tex]g^{-3}h[/tex]
Apply law of indices to change the exponents
[tex]g^{-3}h = \frac{1}{g^3}h[/tex]
Express as products
[tex]g^{-3}h = \frac{1}{g^3} \times h[/tex]

How to put y=14x-62 in standard form, pls explain.
Answer:
14x - y = 62
Step-by-step explanation:
Hi there!
We are given the equation y=14x-62 and we want to put it into standard form.
Standard form is ax + by = c, where a, b, and c are free integer coefficients, but a and b cannot be equal to zero, and a cannot be negative
The equation is currently in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept
Since standard form has the term with x in it on the left side, we can move 14x to the left side (subtract 14x from both sides)
y = 14x-62
-14x -14x
_________________
-14x + y = -62
Remember that a (coefficient of x) cannot be negative. So multiply everything by -1 to change the sign of all the terms
-1(-14x + y) = -1(-62)
14x - y = 62

The equations -6x + 3y = 6 and x² + y = 10 intersect at the
coordinates (a, b) and (c,d).
(Hint: (a, b) is in Quadrant III)
What is the value of a?
What is the value of b?
What is the value of c?
What is the value of d?
The values of the letters in coordinates (a, b) and (c,d) are;
a = -4
b = -6
c = 2
d = 6
We are given two equations;
-6x + 3y = 6 ---(eq 1)
x² + y = 10 ---(eq 2)
We are told that they intersect at coordinates; (a, b) and (c, d).Let us make y the subject in eq 2 to get;
y = 10 - x² --(eq 3)
Let us put 10 - x² into eq 1 to get;-6x + 3(10 - x²) = 6
expanding further gives;
-6x + 30 - 3x² = 6
rearranging gives;
3x² + 6x - 24 = 0
Using online quadratic equation solver, we have;
x = -4 and x = 2
Putting x = -4 into eq 3 gives;
y = 10 - (-4)²
y = 10 - 16
y = -6
Putting x = 2 into eq 3 gives;
y = 10 - (2)²
y = 10 - 4
y = 6
Thus, the coordinates are; (-4, -6) and (2, 6)Comparing with (a, b) and (c,d), we have;
a = -4
b = -6
c = 2
d = 6
