WILL GIVE BRAINLIST ive seen this problem so many times and I've tried my best to solve it but I really need some help here

Answers

Answer 1

Answer:

Answer:

m ABC = 270°

Step-by-step explanation:

Note that the measure of the circle = 360°

m CA = 90°, thus

m ABC = 360° - m CA = 360° - 90° = 270°

Answer 2

Answer:

Answer:

Let O be the center of the circle.

<COA = 90*

<FOE = <AOB = 146*

Considering that a circle is 360* we have <BOC = 124*

The Arc ABC is <AOB + <BOC = 124 + 90 =214*.

What are Arithmetic operations?

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

/ Division operation: Divides left-hand operand by right-hand operand

W have been given that It takes 2 1/2 poster boards to display half of your project.

Here 2 1/2 poster boards = 2.5 poster board

Let you need poster boards would be x for your entire project

We can write this as a ratio as

2.5 poster board : 0.5 of project = x : 1 project

⇒ 2.5/0.5 = x/1

⇒ x = 25/5

⇒ x = 5

Therefore, you will need 5 poster boards for the entire project.

If something in a store costs $45, and the markup is 35%, what is the selling price?

Answers

$45...............100%
x...................35%
x=35*45 x=1575 x= 15.75
100 100
x+$45= ?
$15.75+$45 = $60.75

So you take the price u start with
45
Divide by 100
.45
Multiply by percent increase or decrease
.45 x 35 = 15.75
Add or subtract to original price (add if mark up, subtract if mark down)
45 + 15.75 = $60.75

6/9=c/6 what does c equal?

Answers

$\frac { 6 }{ 9 } =\frac { c }{ 6 } \n \n \frac { 2 }{ 3 } =\frac { c }{ 6 } \n \n 6\cdot \frac { 2 }{ 3 } =\frac { c }{ 6 } \cdot 6$

$\n \n c=\frac { 12 }{ 3 } \n \n \therefore \quad c=4$

C=4 because 4/6 is equivalent to 6/9 and they would reduce down to 2/3

PLEASE HELP! Im not very good at math

Answers

Answer:

The answer provided is incorrect, the mistake is in the division between the monomials $x^{(6)/(5)}$ and $x^{(2)/(5)}$ that is equal to $x^{(4)/(5)$ not $x^3$ , because we must mantain the same base "x" and subtract the expoents that are $(6)/(5) - (2)/(5) = (4)/(5)$ .

Step-by-step explanation:

In order to simplify that question we need to multiply, divide and power monomials with the same base "x". When we multiply monomias with the same base we sum the expoents, to divide we subtract the expoents and to power them we multiply the expoents. Therefore to simplify the equations we must do:

$(\frac{x^{(2)/(5)}*x^{(4)/(5)}}{x^{(2)/(5)}})^(1)/(2)\n(\frac{x^{(6)/(5)}}{x^{(2)/(5)}})^(1)/(2)\n(x^{(4)/(5)})^(1)/(2)\nx^{(4)/(10)}\nx^{(2)/(5)}$
