what is the measure of A and C

enter your answers in the boxes


m A=___
m C=___

Answers

Answer 1

In a triangle we apply angle sum property of triangle, which is given by:

Sum of angles of triangle =180 degrees.

We are given three angles,

A =(4x-13)

B =15

C =(x+18)

Adding the three angles and equating it to 180,

[tex] (4x-13) +15 + (x+18) =180 [/tex]

combining like terms

[tex] 5x+20 =180 [/tex]

[tex] 5x=180-20 [/tex]

[tex] 5x =160 [/tex]

x=32

angle A = 4x-13 = 4(32)-13 = 115 degrees.

angle C = x+18 = 32 +18 = 50 degrees.

Answer : angle A is 115 degrees and Angle C is 50 degrees.

Cory has a square piece of wood that is 4.5 feet by 4.5 feet. He wants to make a circular tabletop out of it. What is the area of the largest circle that he can cut out of the wood? Round to the nearest tenth.

Answers

In this circle, the diameter is the same as the length of the side of the square.  The diameter is 4.5 ft; so, the radius is 2.25 ft., so. A πr²= π(2.25)²=15.90 ft²

The area of the largest circle is  15.9 feet^2

what is area ?

The area is the amount of space within the perimeter of a 2 D shape. It is    measured in square units, such as cm², m², etc.

formula used to find the area is :

A = π r^2

Given : diameter = 4.5 feet

r = d/2

⇒ 4.5 / 2

⇒ 2.25

r = 2.25

A = π × (2.25)^2

A = 3.14 × 5.0625

A  =  15.89625  feet^2

round to nearest tenth is :

A = 15.9 feet ^2

Hence , the area of the largest circle is 15.9 feet ^2

Help why did I get this wrong? Corrections!!! Janie is analyzing a quadratic function f(x) and a linear function g(x). Will they intersect?

Answers

The quadratic function is f(x) = 2x^2 + 1.
The line is g(x) = 2x
Use www.cymath.com and enter the following line and press enter.

the yearly changes in the population of a town for four consecutive years were, respectively, 25% increase, 25% increase, 25% decrease, and 25% decrease. what is the net present decrease over the four years, rounded to the nearest percent?

Answers

Answer: The net change is a 12.11% decrease.

To see what is going on in this problem, we should write an equation. Let's start by using P to represent the total population.

P x 1.25 x 12.5 x 0.75 x 0.75 = 0.8789

For the increases, we multiplied by 1.25. For the decreases, we multiplied by 0.75.

The final result is the P gets multiplied by 0.8789. In other words it is made smaller by 12.11%.  100% - 87.89% = 12.11%

Tabitha defines a sphere as the set of all points equidistant from a single point. Is Tabitha's definition valid?

Answers

Answer
YES it is VALID.

Explanation.
In 3 dimension, it can be seen that a sphere is a round solid. It is a round object where the distance from the centre to every point on the surface is equal.
Tabitha says that a sphere is a set of all points equidistant from a single point. This single point must be the centre of the sphere for that definition to be true. This definition is correct. 

Answer: Yes, Talid's definition is valid.

Step-by-step explanation:

Definition of sphere:- In geometry , a sphere is a perfectly round three-dimensional shape . It is defined as the set of points that are all at the same distance which is known as radius from a given point in a 3-dimensional space.

Talid's definition:- A sphere as the set of all points equidistant from a single point.

Hence, Talid's definition is valid.

Tim’s bank requires its customers to have a 4-digit personal identification number (PIN) to access their accounts. If each digit can be a value from 0 to 9, and a 4-digit number is randomly generated, what is the probability that the number 1234 will be Tim’s PIN? A. 1 6,561 B. 1 5,040 C. 10,000 D.1 10,000

Answers

Answer:

1/10000

Step-by-step explanation:

There are 10 choices for each of the 4 digits.  This means the total number of choices for the PIN are

10(10)(10)(10) = 10000

The number 1234 will only appear 1 time in this list; this makes the probability it is Tim's PIN 1/10000.

Hence, the probability that the number [tex]1234[/tex] will be Tim’s PIN is

What are digits?

A numerical digit is a single symbol used alone or in combinations, to represent numbers in a positional numeral system.

The name "digit" comes from the fact that the ten digits of the hands correspond to the ten symbols of the common base [tex]10[/tex] numeral system, i.e. the decimal digits.

From the given information,

We have [tex]10[/tex] choices for each of the four digits.  

This means that the total number of choices for the PIN is:-

[tex]10(10)(10)(10) = 10000[/tex]

The number [tex]1234[/tex] will only appear one time in this list which makes the probability of the form Tim's PIN  [tex]\frac{1}{10000}[/tex].

Hence, the probability that the number [tex]1234[/tex] will be Tim’s PIN is [tex]\frac{1}{10000}[/tex].

You work for a landscaper that has a customer needing to seed an area of land 80 feet by 40 feet in size. The garden center has 5-pound bags of grass seed. Each bag of seed can cover 25 square yards of land.

You calculate that the area you need to seed is 3200 square feet. You divide by 25 to find that you need 128 bags to seed the area. Is this correct?
A) Yes.
B) No, you need to convert the 3200 square feet to yards by dividing by 3. Then calculate the number of bags.
C) No, you need to convert the 3200 square feet to yards by dividing by 9. Then calculate the number of bags.
D) No, you need to convert the 3200 square feet to yards by multiplying by 9. Then calculate the number of bags.

Answers

1 yard = 3 feet
(1 yard)^2 = (3 feet)^2 ... square both sides
1 yard^2 = 9 feet^2
which means 1 square yard is equal to 9 square feet
think of a square yard as a 3x3 square where each smaller square is 1 square foot.

To convert from square feet to square yards, we multiply by the conversion factor (1 yard^2/9 feet^2). Or put simply we multiply by 1/9 which is the same as dividing by 9

This is why the answer is choice C.

Answer:

Since the mulch is measured in yards you need to either convert the area to be seeded to yards or the bag to feet. No, you need to convert the 3200 square feet to yards by dividing by 9. Then calculate the number of bags.

Given the lengths of two sides of a triangle, find the range for the length of the third side (between what two numbers should the length of the third side be). Write the inequalities for each case. 11.5 and 23.6

Answers

The shortest the third side can be is the difference of the other two sides:
.. 23.6 -11.5 = 12.1
The longest the third side can be is the sum of the other two sides:
.. 23.6 +11.5 = 35.1

12.1 < third side < 35.1

Final answer:

To determine the range for the length of the third side of a triangle with side lengths 11.5 and 23.6, we apply the triangle inequality theorem which tells us that the third side must be greater than 12.1 and less than 35.1.

Explanation:

To find the range for the length of the third side of a triangle when given the lengths of two sides, one must use the triangle inequality theorem. This theorem states that the length of any side of a triangle is less than the sum of the lengths of the other two sides but greater than the absolute difference between these lengths. Given the side lengths of 11.5 and 23.6, the inequalities would be:

The length of the third side must be greater than the absolute difference between 23.6 and 11.5, which is 12.1. Therefore, the third side > 12.1.The length of the third side must also be less than the sum of 23.6 and 11.5, which is 35.1. Therefore, third side < 35.1.

Combining these inequalities gives us the range: 12.1 < third side < 35.1.

Which statements are always true regarding the diagram? Check all that apply.
CAN SOMEONE PLEASE ANSWEERRRRRR

m∠3 + m∠4 = 180°
m∠2 + m∠4 + m∠6 = 180°
m∠2 + m∠4 = m∠5
m∠1 + m∠2 = 90°
m∠4 + m∠6 = m∠2
m∠2 + m∠6 = m∠5

Answers

m∠3 + m∠4 = 180°
As these 2 angles make up a straight line, the sum of the magnitude of angles is 180° so this is true 

m∠2 + m∠4 + m∠6 = 180°
these 3 angles are the interior angles of a triangle. the sum of all the interior angles of a triangle sum up to 180° so this is true.

m∠2 + m∠4 = m∠5
for this statement, use the previously stated concepts 
m∠2 + m∠4 + m∠6 = 180°
m∠5 + m∠6 = 180°
since both equations are equal lets put them into one equation
m∠2 + m∠4 + m∠6 =m∠5 + m∠6
since m∠6 is common for both sides lets cancel it out which leaves us with 
m∠2 + m∠4 = m∠5
therefore this statement is true 

m∠1 + m∠2 = 90°
sum of the angles making up a straight line is 180 °, therefore this is incorrect

m∠4 + m∠6 = m∠2
lets use the following equation
m∠2 + m∠4 + m∠6 = 180° 
if m∠6 + m∠4 = m∠2
then using this we substitute in the previous equation
m∠2 + ∠m∠2 = 180°
m∠2 = 90°
so this angle should be a right angle, but in the diagram its not a right angle therefore this is incorrect 

m∠2 + m∠6 = m∠5
since 
m∠5 + m∠6 = 180°
m∠2 + m∠4 + m∠6 = 180° 
then putting both the equations in one as they are both equal
m∠2 + m∠4 + m∠6 = m∠5 + m∠6
this shows that 
m∠2 + m∠4 = m∠5 
then m∠4 should be equal to m∠6
but judging from the sides opposite to the angles m∠4 and m∠6 the sides aren't equal so these angles too cannot be equal so this statement is wrong.
m∠3 + m∠4 = 180°
m∠2 + m∠4 + m∠6 = 180°m∠2 + m∠4 = m∠5

How to solve 6+5c=-29

Answers

6 + 5c = -29
•You are trying to find C
Therefore you make C your subject by subtracting 6 on both sides then divide by 5.
Like this ;
6 - 6 + 5c = -29 - 6
5c/5 = -35/5
c = -7
hence
C = -7.

To check or prove that your answer is correct, simply sustitute (-7) into the equation in place of C and if the result is -29 than its the correct answer.
•Check;
6 + 5 (-7) = ?
6 + (-35) = ?

6 - 35 = -29
Your answer is proved so C = -7

The value of equation 6+5c=-29 is c= -7.

What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

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:

Equation: 6+5c=-29

Solving the equation for c

6+5c=-29

Subtract 6 from both side

6 + 5c - 6 = -29 - 6

5c = -35

Divide both side by (5) we get

5c / 5 = -35 /5

c= -7
