i need to solve this equation: x= r-h/ y
for h and then for r

Answers

x= r-h/y
h= xy-r/-1
r= xy+h

Answer:

[tex]h=r-xy[/tex]

[tex]r=xy+h[/tex]

Step-by-step explanation:

[tex]x=\frac{r-h}{y}[/tex]

Solve the equation for h

We need to get 'h' alone

[tex]x=\frac{r-h}{y}[/tex]

multiply y on both sides

[tex]xy=r-h[/tex]

Now add h on both sides

[tex]xy+h=r[/tex]

Subtract xy from both sides

[tex]h=r-xy[/tex]

Now solve the equation for 'r'

[tex]x=\frac{r-h}{y}[/tex]

multiply y on both sides

[tex]xy=r-h[/tex]

Now add h on both sides

[tex]xy+h=r[/tex]

[tex]r=xy+h[/tex]

Sara is selling cookies and brownies as a fundraiser for the school band. She charges $2.25 for two cookies and one brownie. She charges $5.75 for four cookies and three brownies. How much does Sara charge per cookie? How much per brownie?
A. $0.50 per cookie, $1.25 per brownie
B. $0.75 per cookie, $1.50 per brownie
C. $0.25 per cookie, $1.00 per brownie
D. $1.00 per cookie, $1.00 per brownie

Answers

Answer:

The cost of the  $0.5 per cookies and $1.25 per brownie.

Option (A) is correct.

Step-by-step explanation:

Let us assume that the cost of the cookies =x

Let us assume that the cost of the brownie = y

As given

Sara is selling cookies and brownies as a fundraiser for the school band.

She charges $2.25 for two cookies and one brownie.

Than the equation becomes

2x + y = 2.25

She charges $5.75 for four cookies and three brownies.

4x + 3y = 5.75

Than two equation are

2x + y = 2.25  and 4x + 3y = 5.75

Multiply 2x + y = 2.25  by 3 and subtracted from 4x + 3y = 5.75

4x - 6x + 3y - 3y = 5.75 - 6.75

-2x = - 1

2x = 1

[tex]x = \frac{1}{2}[/tex]

x = $0.5

Put in the equation 2x + y = 2.25

2 × 0.5 + y = 2.25

1 + y = 2.25

y = 2.25 - 1

y = $1.25

Therefore the cost of the  $0.5 per cookies and $1.25 per brownie.

Option (A) is correct.

The volume of a rectangular prism can be computed using the formula V = lwh. What is the height of a prism that has a volume of 2376 cubic centimeters, a length of 18 centimeters, and a width of 11 centimeters

Answers

18x11=198
198x12= 2376






Answer:

The height of the prism is approximately [tex]\(12\)[/tex] centimeters.

Explanation:

To find the height ([tex]\(h\)[/tex]) of the prism, we can rearrange the formula for volume to solve for [tex]\(h\):[/tex]

[tex]\[ V = lwh \][/tex]

We can rewrite this formula to solve for [tex]\(h\):[/tex]

[tex]\[ h = \frac{V}{lw} \][/tex]

Given:

- Volume ([tex]\(V\)[/tex]) = 2376 cubic centimeters

- Length ([tex]\(l\)[/tex]) = 18 centimeters

- Width ([tex]\(w\)[/tex]) = 11 centimeters

Substitute these values into the formula to find the height:

[tex]\[ h = \frac{2376}{18 \times 11} \][/tex]

[tex]\[ h = \frac{2376}{198} \][/tex]

[tex]\[ h \approx 12 \text{ centimeters} \][/tex]

So, the height of the prism is approximately [tex]\(12\)[/tex] centimeters.

Answer:

the pair would be 3/18 and 2/18

The pair of fractions, 1/6 and 1/9, can be rewritten as 3/18 and 2/18, respectively, using the common denominator of 18.

We have,

The prime factorization of 6 is 2 * 3.

The prime factorization of 9 is 3 * 3.

To find the LCM, take the highest power of each prime factor:

LCM = 2 * 3 * 3 = 18

The common denominator for 1/6 and 1/9 is 18.

To rewrite the fractions using the common denominator of 18:

1/6 = (1/6) * (3/3) = 3/18

1/9 = (1/9) * (2/2) = 2/18

Thus,

A turtle fell to the bottom of a deep well. The turtle climbed up 2 meters on the first day, but slipped back 1 meter as he rested. The second day, the turtle climbed double the distance of the previous day, but slipped and lost ½ of the day’s climbed distance as he rested. This pattern continued until the end of the fourth day, when the turtle realized he was halfway to the top of the well. How deep was the well?

Answers

22 meters and your welcome m8.

Analyzing the climbing pattern of the turtle for four days shows that it climbed 15 meters which is halfway to the top, thus the entire depth of the well is 30 meters.

The question asks for the determination of the depth of a well based on a pattern observed in a turtle's attempt to climb out of it. To do this, we need to analyze the climbing and slipping pattern for four days until the turtle is halfway out of the well.

On the first day, the turtle climbed up 2 meters and slipped back 1 meter, netting a 1 meter gain. On the second day, the distance climbed is double that of the previous day (2 meters x 2 = 4 meters), but the turtle loses half of it while resting, which means a gain of 2 meters for the second day (4 meters / 2 = 2 meters). Following the pattern:

Day 1: +2 - 1 = +1 meterDay 2: +(2 x 2) - (4 / 2) = +2 metersDay 3: +(4 x 2) - (8 / 2) = +4 metersDay 4: +(8 x 2) - (16 / 2) = +8 meters

The total distance climbed after four days is 1 + 2 + 4 + 8 = 15 meters. Since this is halfway to the top, the entire depth of the well would be 15 meters  imes 2 = 30 meters.

In the talent show, 6 students plan to sing, 7 students plan to dance, and 2 students plan to tell jokes. Rick said that the ratio of singers to joke-tellers is 6 to 2. Leah said that the ratio of joke-tellers to singers is 1 to 3. Who is correct? Explain why.

Answers

They are both right but leahs answer is simplified and reversed and ricks is not. I hope this helped.

Leah is correct because the ratio of 6 singers to 2 joke-tellers simplifies to 3 to 1. When we reverse this ratio to represent joke-tellers to singers, it becomes 1 to 3, which is what Leah stated

The question is asking us to compare two different ratios and decide which one is correct. Rick stated the ratio of singers to joke-tellers is 6 to 2. In its simplest form, this ratio can be reduced to 3 to 1 when we divide both numbers by 2. On the other hand, Leah stated the ratio of joke-tellers to singers is 1 to 3, which is the inverse of the first ratio.

Since the ratio of singers to joke-tellers is indeed 6 to 2, which simplifies to 3 to 1, that means for every 3 singers, there is 1 joke-teller. Therefore, Leah's statement of the ratio is correct, as it provides the simplified form while Rick gives the unsimplified form. The order of terms in a ratio is important, and Leah's presentation maintains the correct order while also presenting the simplest form of the ratio

Which one of the following is an arithmetic sequence?

A. −2, 1, 4, 7, 10, . . .
B. 2, 3, 5, 7, 11, 13, 17, . . .
C. 5, 0, −1, −3, −7, . . .
D. .35, .5, .85, 1.1, 1.22, . . .

Answers

arithmetic sequences are sequences who have the same difference every where. for example 0,2,4,6,8 is an arithmetic sequence since the difference between any two terms is equal to 2
we express this mathematically by saying let q be the common difference let a(n) be the nth term of a sequence than the sequence is only arithmetic if and only if for (1st)to(n-1th term) the difference  a(n+1)=a(n)+q and a(n)=q*n
so let us check the choices
A)-2,1,4,7,10 is arithmetic since the common difference is 3
B)2,3,5,7,11,13,17 is not arithmetic since there is no common difference
c)5,0,-1,-3,-7 is not arithmetic since there is no common difference
D)0.35,0.5,0.85,1.1,1.22 isn't arithmetic since there is no common difference

Final answer:

Option A (-2, 1, 4, 7, 10, ...) is an arithmetic sequence because there is a consistent common difference of +3 between each term. The other options do not show a constant difference between terms, so they are not arithmetic sequences.

Explanation:

To determine which of the sequences is an arithmetic sequence, we look for a constant difference between successive terms. An arithmetic sequence is a sequence of numbers in which each term after the first is found by adding a constant, known as the common difference, to the previous term.

A. −2, 1, 4, 7, 10, . . . - The difference between terms is consistently +3, so this is an arithmetic sequence.

B. 2, 3, 5, 7, 11, 13, 17, . . . - The sequence consists of prime numbers and does not have a consistent difference. Not an arithmetic sequence.

C. 5, 0, −1, −3, −7, . . . - The differences between terms here change; they are not constant. Not an arithmetic sequence.

D. .35, .5, .85, 1.1, 1.22, . . . - The differences between terms do not remain the same, so it's not an arithmetic sequence.

Our answer is A: −2, 1, 4, 7, 10, . . .. This is the only arithmetic sequence from the given options as it has a consistent common difference of +3 between each term.

How do you write a recursive formula

Answers

You need to show how a term of formula is based on a previous term.

For example, let's say you have the sequence 3, 6, 9, 12, ...
(multiples of 3).

As a regular function, you can have y = 3x, for the domain of all integers greater than 0. Since the domain is 1, 2, 3, 4, ..., when you multiply those numbers by 3, to get y, you generate the sequence.

To define the sequence recursively, you must base each new number on the previous number.

Start by stating the first term.

a1 = 3

If you look at the sequence, 3, 6, 9, ..., you see it has a constant difference, and it is an arithmetic sequence, so to generate a term, you need to add 3 to the previous term.

Once we defined the first term to be 3, the next term is a2 = 3 + 3 = 6
Then a3 = 6 + 3 = 9, etc.

To define the sequence recursively, just generalize the addition of 3 to a term to get the next term.

[tex] a_{1} = 3 a_{n} = 3 a_{n - 1} [/tex]
