Can more than one triangle be drawn with one side length of 4 centimetres and 2 centimetres and an included angle of 50°? Explain.

Answers

Answer: No .

Step-by-step explanation:

If we make two triangles with lengths of 4 centimeters and 2 centimeters and  an included angle of 50°, then by SAS congruence postulate both triangle will be congruent.

According to the definition of congruence , if two shapes are congruent then they have equal size and shape.

i.e. they look exactly same.

It means only one triangle is possible with the given measurement .

SAS congruence rule : It says that if two sides and the included angle of a triangle are congruent to two sides and the included angle of another triangle, then  we can say that these two triangles are congruent.

1) It’s true because -5 is way smaller than 3. All the negatives are below the 0 and everything below the 0 is lower than everything above the 0.

2) false. it’s false because in order -5 isn’t even close to 3

3) false.. It’s false because when you have those 2 line that are covering the -5 that means it’s “transforming” into a positive number. So therefore it’s would be 5>3 that would make it true.

4) True. it’s true because like I said the to lines mean the absolute value of something. So it’s being switch to a positive number

For a birthday party, Mr. Perkins orders 8 chocolate chip cookies and 16 sugar cookies. Each cookie is the same price. He also picks up a cupcake for himself, which costs $2.75. The total bill is $44.03. What is the cost of a cookie?



Remember money is rounded to the nearest hundredth.

Answers

Answer:

2 dollars

Step-by-step explanation:

Answer:

$1.72

Step-by-step explanation:

First, subtract the cupcake from the total

44.03-2.75=41.28

Find out the total number of cookies

8+16=24

Then divide the total cookie price by the total number of cookies

41.28÷24=1.72

Each cookie costs $1.72

What is 4x +2 = 9x + 5

This is a challenge whoever gets it right gets brainly why not

Answers

Question :-

What is 4x +2 = 9x + 5

____________________

Solution :-

Given Information :-

4x + 2 = 9x + 5

To Find :-

The value of x

Calculation :-

⇒ 4x + 2 = 9x + 5

Now, subtract 2 from both Left Hand Side and Right Hand Side to eliminate + 2 in Left Hand Side,

⇒ 4x + 2 - 2 = 9x + 5 - 2

⇒ 4x = 9x + 3

Now, subtract 9x from both Left Hand Side and Right Hand Side to eliminate 9x in Right Hand Side,

⇒ 4x - 9x = 9x - 9x + 3

⇒ - 5x = 3

Now, Transpose - 5 to Right Hand Side,

⇒ x = [tex] \sf \frac{ 3}{ - 5} [/tex]

∴ x = [tex] \sf \frac{ 3}{ - 5} [/tex]

____________________

Final Answer :-

Value of 'x' is [tex] \sf \frac{ 3}{ - 5} [/tex].

What will be the resulting equation when you substitute the first equation (-3x + 5) in for y in the second equation?

Equation 1: y=(-3x+5)
Equation 2: 5x-4(y)=-3

Answers

Answer:

See below.

Step-by-step explanation:

Substituting for y:

5x - 4(-3x + 5) = -3

5x + 12x - 20 = -3

17x = -3 + 20

17x = 17.

x = 1.

Answer:

Step-by-step explanation:Substituting for y:

5x - 4(-3x + 5) = -3

5x + 12x - 20 = -3

17x = -3 + 20

17x = 17.

Help pleaseee.The answer has to be 50,40, or 90

Answers

Answer:

40

Step-by-step explanation:

We know that angle FGE is equal to 50 and angle GEC is equal to 90 degrees because of the square. Therefore, we add them together. 50+90=140. We know that a triangle is equal to 180 degrees so we have to subtract 140 from 180. 180-140 is equal to 40. Therefore, angle FCE is equal to 40.

If this has helped you please mark as brainliest

Answer:

<FCE = 40

Step-by-step explanation:

The sum of angles in a triangle is (180) degrees. This holds true for the given triangle. Therefore, one can form an equation,

<FGE + <FCE + <GEC = 180

Substitute,

50 + <FCE + 90 = 180

(Note that a box around an angle indicates that the angle measure is (90) degrees)

Simplify,

140 + m<FCE = 180

Inverse operations,

140 + <FCE = 180

<FCE = 40

Which account recorded a greater percentage change in amount of money over the previous year? Justify your answer.

Answers

Answer:

This was timed and posted awile ago but I don't have the answer either way.

Step-by-step explanation:

Answer:

A) The price of product A is increasing by 3% per year.

(B) The product A recorded a greater percentage change in price over the previous year.

Step-by-step explanation:

(A)

The function representing the price, in dollars, of product A after x years is:

FA(x)=0.69*(1.03)x

The function  FA(x)can be written as:

FA(x)=0.69*1+(0.03)x

The function FA(x) is similar to the exponential growth function, y=a(1+r)x .

Here r is the growth rate.

Thus, it can be said that the price of product A is increasing by 3% per year.

(B)

Consider the data of product B for the year 3 and 4.

The price of product B for year 3 and 4 are 10,303.01 and 10,406.04.

Compute the percent price change from year 3 to 4 as follows:

10406.04-10303.01/10303.01*100

which is 0.999%

~1%

The price of product B is increasing by 1% per year.

Thus, the product A recorded a greater percentage change in price over the previous year.

The area of the triangle below is 1/8 square inches . What is the length of the base ? Express your answer as a fraction in simplest form.

Answers

Answer:

1/4

Step-by-step explanation:

(1/8)/(1/2)=(1/8)×2

so, (1/8)×2=2/8, but, wencan simplify it to 1/4.

The length of the base of the right-angle triangle will be 1 / 2 inches.

What is the area of the right-angle triangle?

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

The area of the right-angle triangle is given as

A = 1/2 x B x H

Where B is the base and H is the height of the right triangle.

The area of the triangle below is 1/8 square inches. And the length of the perpendicular will be 1/2 inches.

Then the length of the base will be

A = 1/2 x B x H

1/8 = 1/2 x B x 1/2

1/8 = 1/4 x B

B = 1/2

The length of the base of the right-angle triangle will be 1/2 inches.
