Need Help Again Just On Number 3

Answers

Answer 1
Im going to start with my example for a. So you have to figure out how you can get to 8 from 2. So that would be 2*4=8. And whatever you do to the top, you must also do to the bottom. So for the top we multiplied by 4, so we also have to multiply the bottom by 4. So that would be 26*4=104. So your total/answer would be 8 teachers= 104 students. In another way, for f. it would be the same but you have to divide instead since 9 is bigger than 3. Hope this helped ! :)

Since 43 is a 2 digit odd number is it a composite and why

Answers

the answer is it is also prime
It is not composite because nothing times itself equals 43. It is prime though which means that nothing times itself equals it. So that means that it is not composite it is prime.

The undefined terms line and plane are needed to precisely define which mathematical term?
line segment
perpendicular lines
parallel lines

Answers

The correct answer is:

parallel lines  

Explanation:

Parallel lines are two lines in a plane that never intersect.  This means the definition uses the undefined terms "line" and "plane."

The undefined terms line and plane are needed to precisely define which mathematical term will be parallel lines so option (C) will be correct.

What are a line and plane?

A line section that can connect two places is referred to as a segment.

In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.

A plane is a surface that is straight in nature a plane has a certain area but in most cases.

We know that parallel line are those lines which not intersect and lies on a plane.

Hence there are two things that are needed first is a line and the second is a plane the plane should be single for both lines not different.

I suck a writing proofs in geometry.... please someone explain it to me, i cant seem to reconize what's going on. I need major help in properties of congruent proofs.

Answers

Congruence Properties

In earlier mathematics courses, you have learned concepts like the commutative or associative properties. These concepts help you solve many types of mathematics problems. There are a few properties relating to congruence that will help you solve geometry problems as well. These are especially useful in two-column proofs, which you will learn later in this lesson!

The Reflexive Property of Congruence

The reflexive property of congruence states that any shape is congruent to itself. This may seem obvious, but in a geometric proof, you need to identify every possibility to help you solve a problem. If two triangles share a line segment, you can prove congruence by the reflexive property.

The rectangular backboard of a basketball court needs to be assembled. Its area is given as 18,900 cm2 and the width as 1.8 m.

What is the backboard’s length in metres?

Answers

Answer: 
1.05

Explanation: 
The formula for area is:
A = l • w 
So to find the length, you would rearrange to make:
l = A ÷ w 
1.8 m = 180 cm 
So: 
l = 18,900 ÷ 180 
l = 105 cm 
105 cm = 1.05 m

Answer:

1.05 m

Step-by-step explanation:

The area of the rectangular backboard is A = 18900 cm²

And the width is w = 1.8 m = 1.8 ×100 = 180 cm

The area of the rectangle is given by

[tex]A=l\cdot w[/tex]

Substituting the known values

[tex]18900=l\cdot 180\\\\l=\frac{18900}{180}\\\\l=105\text{ cm}[/tex]

Thus, the length of the backboard's is 105 cm = 1.05 m

Veronica is shopping for school clothes. She wants to buy pants and shirts. The cost of her clothes can be found using the expression 30x + 25y where x is the number of pants and y is the number of shirts. She will also have to pay 8% tax. If Veronica buys two pants and eight shirts, what expression could be used to determine the total cost of the bill including 8% tax?

Answers

Hey there.

I'll list the variables so we're clear.

= 2, y = 8

So far the expression looks like this: (i'll come back to the 8%)

30(2) + 25(8) 

60 + 200 = 260

Cool, now we have the price before tax. We can add the sales tax by multiplying $260 by 8% as a decimal.

260 · 0.08 = 20.80

260 + 20.80 + 280.80

The total cost of Veronica's bill is $280.80

Cheers!


Final answer:

To find the total cost of Veronica's school clothes including 8% tax, first calculate the cost before tax with her specific quantities of pants and shirts, and then add the tax. The final expression shows a total cost of $280.8.

Explanation:

Veronica is shopping for school clothes, and the cost of her clothes can be found using the expression 30x + 25y, where x is the number of pants and y is the number of shirts. She will also have to pay 8% tax. If Veronica buys two pants and eight shirts, the expression to determine the total cost of the bill including 8% tax would be:

First, substitute x = 2 (pants) and y = 8 (shirts) into the expression to find the total before tax: 30(2) + 25(8).Calculate the cost before tax: 60 + 200 = 260.Calculate the total with 8% tax: 260 + (0.08 × 260).The final expression to determine the total bill is: 260 + 20.8 = 280.8.

What is 12x3 – 9x2 – 4x + 3 in factored form?

Answers

The factors of the given polynomial 12x^3-9x^2-4x+3  are

(4x-3) (3x^2-1).

Given: Polynomial  12x^3-9x^2-4x+3        

We have factorized the given polynomial.

What is the meaning of factors?

The factor means a number that can be multiplied or divided to produce a given number.

Consider the given polynomial 12x^3-9x^2-4x+3.

We will factorize using a grouping of terms,

Taking  3x^2 common from the first two terms and -1 common from the last two terms, we have,

3x^2(4x-3)-1(4x-3)

     

Now, again taking (4x-3) common,  we have,

(4x-3)(3x^2-1)

Thus, The factors of the given polynomial are (4x-3)(3x^2-1).

https://brainly.com/question/25829061#SPJ3

Final answer:

The factored form of 12x3 - 9x2 - 4x + 3 is (3x2 - 1)(4x - 3).

Explanation:

The expression 12x3 - 9x2 - 4x + 3 can be factored as follows:

First, identify any common factors among the terms. In this case, the greatest common factor (GCF) is 1.

Next, group the terms:

12x3 - 9x2 - 4x + 3 = (12x3 - 9x2) + (-4x + 3)

Factor out the GCF from each group:

12x3 - 9x2 = 3x2(4x - 3)

-4x + 3 = -1(4x - 3)

Combine the factored terms:

(3x2 - 1)(4x - 3)

Therefore, the factored form of 12x3 - 9x2 - 4x + 3 is (3x2 - 1)(4x - 3).
