Jan was charged a 5% tax rate for his blazer

To fin this we first must look at how much was actually charged in sales tax.

$39.90 - $38 = $1.90

Okay, so Jan was charged $1.90 sales tax. Now all we need to do is find out how much of a percentage $1.90 is of $38 or. another way to say it, how many much of $38, $1.90 will take up.

to do this we simply divide 1.9 into 38. So,

38 ÷ 1.9 = 20

This means that 1.9 goes into 38 twenty times. If that is the case, then our sales tax is 5%. This is because the percentage scale is based off a 1-100 scale and 20 of 100 is 5% because 5*20=100.

All of this just basically means that if we multiplied 1.9 * 20 we would get 38 which is 100% of 38 because 100% of a number is itself.

I hope this helped!!! Have a blessed day :))

39.90 - 38 = 1.90

1.90 / 38 = 0.05 = 5% sales tax rate <===

Two triangles can be formed with the given information. Use the Law of Sines to solve the triangles. A = 56°, a = 12, b = 14

Eva8 [605]

We know that
case 1)
Applying the law of sines
a/Sin A=b/Sin B
A=56°
a=12
b=14
so
a*Sin B=b*Sin A----> Sin B=b*Sin A/a---> Sin B=14*Sin 56°/12
Sin B=0.9672
B=arc sin (0.9672)------> B=75.29°-----> B=75.3°

find angle C
A+B+C=180°-----> C=180-(A+B)----> C=180-(56+75.3)----> C=48.7°

find c
a/Sin A=c/Sin C----> c=a*Sin C/Sin A----> c=12*Sin 48.7°/Sin 56°)
c=10.87-----> c=10.9

the answer Part 1)
the dimensions of the triangle N 1
are
a=12 A=56°
b=14 B=75.3°
c=10.9 C=48.7°

case 2)
A=56°
a=12
b=14
B=180-75.3----> B=104.7°

find angle C
A+B+C=180°-----> C=180-(A+B)----> C=180-(56+104.7)----> C=19.3°

find c
a/Sin A=c/Sin C----> c=a*Sin C/Sin A----> c=12*Sin 19.3°/Sin 56°)
c=4.78-----> c=4.8

the answer Part 2)
the dimensions of the triangle N 2
are
a=12 A=56°
b=14 B=104.7°
c=4.8 C=19.3°

Use factoring to find the zeros. x2 - 9x – 36 = 0

3241004551 [841]

Answer: x=12, x=-3

Step-by-step explanation: For this factored problem, you see that -36 is negative, as well at -9. This shows you that you need to find two numbers that multiply to get -36, and add up to get -9. Two numbers that both satisfy these requirements are -12 and 3. They multiply to get -36, and add to get -9.

Once you have found your values, you plug them into (x+/- __)(x+/- __), which is (x-12)(x+3).

But since the problem asks you to find the zeroes, you set each factor equal to zero, like this:

x-12=0 and x+3=0

Then solve and you have you answer!

Pavel [41]

I believe the answers are:
(f o g) (2)= 1/17 and (f+g) (2)= 17.5

Pleases someone explain

Nikolay [14]

When you have a negative exponent, you move the base with the negative exponent to the other side of the fraction to make the exponent positive.

For example:

$\frac{1}{y^{-2}} =\frac{y^2}{1}$ or $y^2$

$2x^{-3}$ or $\frac{2^1x^{-3}}{1} =\frac{2}{x^3}$

$\frac{1}{x^{-5}} =x^5$

When a base with an exponent is divided by a base with an exponent, you subtract the exponents together. (But you can only combine the exponents when the bases are the same)

For example:

$\frac{x^2}{y}$ (can't combine because they have different bases of y and x)
