The triangles do not meet the criteria of any postulate, therefore, they might not be congruent.

What are Congruent Triangles?

There are criteria that can be used to show that two triangles are congruent to each other. They are:

ASA postulate: This says that two triangles are congruent if they have two pairs of congruent angles and one pair of included congruent sides.SAS postulate: This says that two triangles are congruent is they have two pairs of congruent sides and one pair of included congruent angles.HL postulate: If both triangles have equal hypotenuses and a pair of congruent corresponding legs, then they are congruent triangles based on this postulate.SSS postulate: both triangles are congruent if they have three pairs of congruent sides.

However, two triangles can have three pairs of congruent angles and may not necessary be congruent triangles.

The triangles in the image below shows that the two triangles have three pairs of corresponding congruent angles. This information is not enough to prove they are congruent.

The answer is, C. Might not be congruent.

1. How many pounds of Brazilian Coffee should be mixed with 6 pounds of Colombian Coffee to get

mixture?

Answers

Answer:

12 pounds

Step-by-step explanation:

Colombian Coffee sells for $9.25 per pound. Brazilian Coffee sells for $7.75 per pound.

The management wishes to mix 6 pounds of Colombian Coffee with an amount of Brazilian Coffee so that the mixture sells for $8.25 per pound.

Hence:

Let the number of pounds of Brazilian coffee be represented by = a

$9.25× 6 + $7.75 × a= $8.25 (a + 6)

55.5 + 7.75a = 8.25a + 49.5

Collect like terms

8.25a - 7.75a = 55.5 - 49.5

0.5a = 6

a = 6/0.5

a = 12 pounds

Therefore, 12 pounds of Brazilian Coffee should be mixed with 6 pounds of Columbian nuts

Qd=240-5P
Qs =P
Where qd is the quantity demanded, qs is the quantity supplied and p is the price. Determine the equilibrium quantity before the tax

Answers

Answer:

Equilibrium quantity before the tax = 40 units

Step-by-step explanation:

Given:

Qd = 240 - 5P

Qs = P

Computation:

Qd = 240 - 5P

P = 48 + Qd/5

Equilibrium quantity before the tax

Qd = 240 - 5P

P = 240 - 5P

6p = 240

p = 40

Qd = 240 - 5P

Qd = 240 - 5(40)

Qd = 40

Equilibrium quantity before the tax = 40 units

Which table contains only corresponding x-values and y-values where the value of y is one more than the product of x and 2?

Answers

Answer:

Option (C)

Step-by-step explanation:

Value of y is more than the product of x and 2.

Equation representing the given condition will be,

y = 2x + 1

Therefore, by substituting the values of x in the equation we can get the table for the input - output values for the equation,

x 0 1 2 3 4

y 1 3 5 7 9

Therefore, table given in the Option (C) will be the correct option.

The area of a square shaped yard is 201.5 ft2. Which measurement is closest to the side length of this yard in feet?

Answers

Answer:

a = 14.19 feet

Step-by-step explanation:

Given that,

The area of a square shaped yard is 201.5 ft²

We need to find the side length of this yard in feet.

The area of a square shaped object is given by :

A = a², a is the side length of the object

Put A = 201.5 ft² in above formula,

[tex]201.5=a^2\\\\a=\sqrt{201.5 } \\\\a=14.19\ \text{feet}[/tex]

So, the side of the square yard is 14.19 feet.

What is a function?

A function is defined as the expression that set up the relationship between the dependent variable and independent variable. Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Given function is h(x) = -x + 2, the value of the function at x equal to 4 will be calculated as below:-

h(x) = -x + 2,

h(x) = -(4) + 2,

h(x) = -2

That is a supplementary angle which means it adds up to 180 degrees.

So first you would subtract what you already know
