only 4 b and c please

Answers

Answer:

a) 2L + 2W = 42

b) L = 2W + 3

c) The system is :

2L + 2W = 42

L - 2W = 3

( add the two equations )

3L + (2w - 2w) = 45

3L = 45

L = 45/3

L = 15 ( Length )

L - 2W = 3

15 - 2W = 3

2W = 15 - 3

W = 12/2

W = 6

Step-by-step explanation:

-x² + 10x - 25 = 0

x = {-10±√((10²)-(4*-1*-25) / (2*-1)

x = {-10±√(100-100)} / -2

x = {-10)/-2

x = 5

Amy rolls a 12 sided die numbered from one to twelve.
what is the probability amy rolls a multiple of 4 written
as a percent?

Answers

To find the probability, we'll need to find the number of possibilities with an outcome that we want, as well as the total number of outcomes.

Multiples of 4: 4, 8, 12

---There are 3 possibilities

Total outcomes: 12

3 / 12 = 1/4 = 0.25 = 25%

Probability Amy rolls a multiple of 4 = 25%

At the state fair, 2 bags of mini donuts and 4 turkey legs cost $18.50. for $13.75, you can buy 3 bags of mini donuts and 2 turkey legs.using these amounts, which system of equations can be used to find the cost of 1 bag of mini donuts?

Answers

Let’s use subtraction in this case:

Let Mini donut be D
Let turkey legs be T


(2D + 4T = 18.50)*3
(3D + 2T = 13.75)*2

6D + 12T = 55.50
-6D + 4T = 27.50

8T = 27.5
T = 3.5 The turkey leg is 3.5$


2D + 4(3.5) = 18.50

2D + 14 = 18.50


2D = 4.5
D=2.25


The cost of one mini donut would be 2.25$

Consider the sequence 3, 6, 12, 24, 48, .... (a) Write a recursive rule to represent the sequence. (b) Write an explicit rule to represent the sequence. (c) Find the 15th term in the sequence.

Answers

Answer:

  a. a[1] = 3; a[n] = 2a[n-1]

  b. a[n] = 3·2^(n-1)

  c. a[15] = 49,152

Step-by-step explanation:

Each term of the given sequence is 2 times the previous term. (This description is the basis of the recursive formula.) That is, the terms of the given sequence have a common ratio of 2. This means the sequence is geometric, so the formulas for explicit and recursive rules for a geometric sequence apply.

The first term is 3, and the common ratio is 2.

(a)

The recursive rule is ...

  a[1] = 3

  a[n] = 2×a[n-1]

__

(b)

The explicit rule is ...

  a[n] = a[1]×r^(n-1)

  a[n] = 3×2^(n-1)

__

(c)

The 15th term is ...

  a[15] = 3×2^(15-1) = 3×2^14

  a[15] = 49,152

divide both sides of the equation by 15. 6

Answers

Answer:

Multiply both sides of the equation by n/-2.25

Step-by-step explanation:

[tex]\frac{n}{-225}=15.6[/tex]

[tex]\mathrm{Multiply\:both\:sides\:by\:}-2.25[/tex]

[tex]\frac{n\left(-2.25\right)}{-2.25}=15.6\left(-2.25\right)[/tex]

[tex]\mathrm{Simplify}[/tex]

[tex]n=-35.1[/tex]

~lenvy~

Answer:

The answer is A. (multiply both sides of the equation by n/-2.25).The final answer is n=-35.1.

Step-by-step explanation:

To solve this problem, first, you have to isolate the term of n from one side of the equation.

[tex]\sf{\dfrac{n}{-2.25}=15.6 }[/tex]

The only way to solve this is to multiply both sides by -2.25.

[tex]\sf{\dfrac{n(-2.25)}{-2.25}=15.6(-2.25) }[/tex]

After that, you solve.

Multiply the numbers from left to right.

[tex]\sf{15.6(-2.25)=\boxed{\sf{-35.1}}[/tex]

n=-35.1

Don't forget to use a variable for your final answer.

Therefore, the correct answer is n=-35.1 and A. multiply both sides of the equation by n/-2.25.

I hope this helps you! Let me know if my answer is wrong or not.

Area of square= 625 m sq Perimeter =??

Answers

Answer:

100 m

Step-by-step explanation:

Given :

Area of square = 625 m²

#1) Finding the side length

Area = (side length)²⇒ side length = √Area⇒ side length = √625⇒ side length = 25 m

#2) Calculating perimeter

Perimeter = Total length of the sides of the shapePerimeter = 4 x side length [a square has 4 equal sides]⇒ Perimeter = 4 x 25⇒ Perimeter = 100 m

Answer:

100 m.

Step-by-step explanation:

So the area of a square (or any rectangle) is length (l) x width (w). Additionally, all sides of a square are the same length. So if your area is 625 m sq, then one side length would be the square root of 625, which is 25.

So, as we know that one side length is 25 m, and that the perimeter is all side lengths added together, and that a square has four equal sides,

we can add the four lengths of 25 together: (4)(25) [25+25+25+25].

(4)(25) = 100.

The perimeter of the square is 100 m.

Cameron will spend $285.00 for a car repair. He has $277.00 in the account linked to his debit card. The bank charges a $7 penalty fee per day for using his debit card to make a purchase if he does not have enough funds in his account. What will he pay altogether if he chooses to use his debit card and does not put any more money in his account for 6 days?

Answers

Using proportions, considering the daily penalty fee paid, it is found that he will pay $50 altogether.

What is a proportion?

A proportion is a fraction of a total amount.

In this problem, since he will spend $285.00, having $277.00, he will be $8.00 in debt.

He will pay a penalty fee of $7.00 per day for 6 days, along with the $8.00, hence the total payment in dollars will be given by:

P = 6 x $7.00 + $8.00 = $50.00.

Is this equation an identity? (2x+1)^2-(x+1)^2=3(x+1)^2-1

Answers

Answer:

See below, please

Step-by-step explanation:

Left side

[tex] {(2x + 1)}^{2} - {(x + 1)}^{2} [/tex]

[tex] = (4 {x}^{2} + 4x + 1) - ( {x}^{2} + 2x + 1)[/tex]

Right side

How many solutions does the equation 5x + 3x − 4 = 10 have? (4 points) Zero One Two Infinitely many​

Hey there!

Let's solve this equation.

5x+3x-4=10

add the x's

8x-4=10

add 4 to both sides

8x=10+4

8x=14

divide both sides by 8

x=14/8

Reduce the fraction;

x=7/4 (improper fraction)

x=1+3/4 (mixed number)

Hence, the equation has 1 solution.
