Answer:

31.40 inches

Step-by-step explanation:

Circumference of circle is 2πr where r is radius. We know that r is 5 inches as shown in the image. Therefore:

[tex] \displaystyle{C = 2 \times 3.14 \times 5}[/tex]

Evaluate

[tex] \displaystyle{C = 10 \times 3.14} \\ \\ \displaystyle{C = 31.40}[/tex]

Therefore, the circumference of circle is 31.40 inches

Thank you so much for checking my homework. I really appreciate it!

Answers

Answer: my laptops act crazy so if you can't see the answers please tell me so i can fix it

Step-by-step explanation:

The terms is the number multiples by a variable so 4f and 8 are the terms. The coefficient are the variables next to a number so “f”. The constant is the number so 4 and 8

The terms are 4/5, 3s, and 2. The coefficients are “s”. The constants are 3.

The terms are 9h^2 and 8/9p and The coefficient are h and p. The constant is 9^2 and 8/9.

4. Exponents are a numbers times it self that many times. So 5^2 would be 25. So b^3

5. G^5

6. 8^4

7.6+(3) = 9

8. 2(5) = 10

9. 12-1= 11

10.27/3= 7

11. 10+p because 10 is being added to p

12. Product means the total of addition so n+6

13. n added to 6. the product of 6 and a number n

14. 4 multiples by a number w. 4 times each of a number w.

15. B taken away from 15. A difference of 15 and b

16. 14 subtracted by 3 times z. A difference of 14 and 3 multiplied by z.

17. So first plug in the amount of weeks so 45+3(20) which is 45+60=105 and since the thing cost 125 which means 20 weeks is not enough money.

(please answer each part of the question and label your answer. Thanks!)

Answers

Answer:

Scroll Down Below...

Step-by-step explanation:

Part A: To record an equating defining this position, we can start by canny the total distance camouflaged in d supplementary days. Since the kin drives 350 5 per epoch each surplus era, the total distance marked in d supplementary days is 350d. Adding the beginning 200 5 compelled on the first epoch, the equating enhances:200 + 350d = 1,600Part B: To resolve the equating and find the total number of days the offspring will travel, we need to detach the changeable d. We can start by subtracting 200 from two together hands of the equating:350d = 1,600 - 200350d = 1,400Next, we separate two together parts of the equating by 350 to resolve for d:d = 1,400 / 350d = 4Therefore, the kin will travel for an supplementary 4 days to reach a total distance of 1,600 5.

two lines meet at a point that is also the vertex of an angle. Set up and solve an equation to find the value of m.

Answer:The vale of m is

Step-by-step explanation:

First, we have to find the angle between 24° and 68° and let that angle be- x°

As the right angle,

90° = 68°+ x°

22° = x°

Now,

Angle m = angle x° + 24° ( vertical opposite angles)

m = 22 +24

Step-by-step explanation:

Describe and correct the error in solving the system of linear equations.
5 + 2y = 9
3x - 2y = -1
2x = 10
x = 5

Answers

Answer:

The second equation is incorrect!

Step-by-step explanation:

Let's break this down line by line:

y=2

x=5

1) 5 + 2y = 9 this equation is basically 5 + (2x2) = 9 meaning that y equals 2. This equation is correct!

2) 3x - 2y = -1 becomes (3x5) - (2x2) = which also basically becomes 15 - 4 which in reality equals 11. This means the equation on the second line is incorrect! Because 3x - 2y = -1 is incorrect and it is actually 3x - 2y = 11

3) 2x = 10 is correct because x=5 meaning that this equation would be 2 x 5 = 10!

What are complex numbers?

Complex numbers are those numbers that contain the imaginary and the real part.

A Complex value z is written in a rectangular form as z = x+iy where (x, y) is the rectangular coordinates.

r is the modulus of the complex number and θ is the argument

r =√x²+y² and θ = tan⁻¹y/x

We need to simplify the complex number;

(30-50i)/(3-5i)

Therefore,

(30-50i)/(3-5i) x (3+5i)/(3+5i)

(30-50i) (3+5i)/(9 + 25)

one fifth times x times y times the quantity x squared plus 2 times y end quantity

Answers

Answer: The expression which can be rewritten using a common factor is; xy/10 (x² + 2y).

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

We have the following information given as;

One tenth times x cubed times y plus two tenths times x times y squared using a common factor.

We know that 'times' has to be replaced with multiplication.

Now, we will change this into mathematical expression as;

x³y/ 10 + 2xy²/ 10

Now, the common factor can be ;

xy/10

The Common factor refers to the number and the variables taken as a common factor should be able to completely divide the terms given any expression.

Now, taking it as a common factor, we have the following expression:

xy/10 (x² + 2y)

Hence, the required expression is; xy/10 (x² + 2y).

mr. Duncan just had his condo appraised to find out its value. According to the appraiser, the
ondo is currently worth $202,470. That is 2% higher than the condo was worth when he
ought it several years ago. What was the value of the condo then?

Answers

Answer:

The appraiser said that the condo is currently worth $202,470 and it's 2% higher than the condo was worth when Mr. Duncan bought it several years ago. To find the value of the condo when he bought it, we need to subtract 2% of the current value from the current value.

We can find 2% of the current value by multiplying it by 0.02:

$202,470 x 0.02 = $4,049.4

To find the value of the condo when he bought it, we need to subtract $4,049.4 from the current value:

$202,470 - $4,049.4 = $198,420.6

Therefore, the value of the condo when Mr. Duncan bought it was $198,420.6

The answer is 194,420.6
