Sergio has p paintings in his art collection. He and other local painting collectors agreed to donate a total of 48 paintings to the local museum. In each of the 12 collectors will donate the same number of paintings. How many paintings will Sergio have in his art collection after his donation?

Answers

Answer 1

Answer:

Since there are 48 paintings being donated by 12 collectors, then we can say that each collector will donate 4 paintings.

This means that Sergio will have 4 less paintings then he had before, which was represented by pp . Thus, our expression is now \boxed{p - 4}p−4 .

Answer 2

Answer:

Sergio would have 4 paintings less

Step-by-step explanation:

48 total painting

12 painting collectors donated

They all donated the same amount

So each local painting collector donates the same amount of paintings

so 48 divided by 12 = 4

So each painting collector would donate 4 painting each

We don't know how much painting Sergio had in total before but we do know how much he donated which is 4

How much is a combo meal?
How much is a salad?

Answers

Answer:

The cost of a combo meal is $8 and a salad is $4.

Step-by-step explanation:

You have to form simultaneous equations with the given informations. Let combo meal be m and salad is s :

[tex]m + s = 12 - - - (1)[/tex]

[tex]2m + s = 20 - - - (2)[/tex]

Next, you have to solve these equations :

[tex](2) - (1)[/tex]

[tex]2m + s - m - s = 20 - 12[/tex]

[tex]m = 8[/tex]

[tex]sub \: \: m = 8 \: \: into \: \: (1)[/tex]

The CEO of a cell-phone company has recently noticed a 26% sales decrease in the month of July compared to June. Let n represent June’s sales. If y represents July’s sales, which equation can be used to determine the sales in July?

Answers

Answer:

y = n - 0.26n

y = 0.74n

Step-by-step explanation:

The equation that can be used to express the function above is given an Exponential Decrease function

Where:

y = a(1 - r)^t

Where

y = July sales

a = n = June sales

r = rate of decrease = 26% = 0.26

t = time in months = June to July = 1 month

t = 1

Hence, our equation =

y = n( 1 - 0.26)¹

y = n(1 - 0.26)

y = n - 0.26n

y = 0.74n

The equation that can be used to determine the sales in July is given as:

y = n - 0.26n

y = 0.74n

The price p of a pizza is $6.95 plus $0.95 per topping t on the pizza, write a function rule

Answers

Answer:

y= 6.95+0.95t

Step-by-step explanation:

Given data

The price p of a pizza is $6.95

plus $0.95 per topping

let the number of toppings be  t

and let the total cost be y

Hence for any number of topping t the cost function is

[tex]y= 6.95+0.95t[/tex]

The function rule for the prize of a pizza is

[tex]P=0.95t +6.95[/tex]

Given :

The price p of a pizza is $6.95 plus $0.95 per topping t on the pizza

Initial price of the pizza is 6.95

The cost of each topping is 0.95 .

Let 't' be the number of toppings on the pizza

Price of  a pizza = initial cost of pizza + cost per pizza ( number of toppings)

[tex]p=6.95 +0.95(t)\\P=0.95t +6.95[/tex]

The function rule for the prize of a pizza is

[tex]P=0.95t +6.95[/tex]

D. x = 145, y = 35

Answers

Answer:

        B.  x = 135, y = 45

Step-by-step explanation:

x° + y° = 180°        {suplementary angles}

x° = 3y°               {corresponding angles by parallel lines}

So:

3y° + y° = 180°

y° = 45°

y = 45

x° = 3×45° = 135°

  solve for f(n) in terms of f(n-1)

Step-by-step explanation:

In general, you solve for f(n) in terms of f(n-k) for k = 1, 2, 3, ....

__

Usually, such questions arise in the context of arithmetic or geometric sequences.

Arithmetic sequence

The explicit formula for an arithmetic sequence has the general form ...

  a(n) = a(1) +d(n -1) . . . . . . . first term a(1); common difference d

The recursive formula for the same arithmetic sequence will look like ...

  a(1) = a(1) . . . . . . . the first term is the first term

  a(n) = a(n-1) +d . . . the successive terms are found by adding the common difference to the term before

__

Note: The explicit formula may be given as the linear equation a(n) = dn +b. Then the first term is a(1) = d+b.

__

Geometric sequence

The explicit formula of a geometric sequence has the general form ...

  a(n) = a(1)·r^(n -1) . . . . . . first term a(1); common ratio r

The recursive formula for the same geometric sequence will be ...

  a(1) = a(1) . . . . . . the first term is the first term

  a(n) = a(n-1)·r . . . the successive terms are found by multiplying the term before by the common ratio

__

Note: The explicit formula may be given as the exponential equation a(n) = k·r^n. Then the first term is a(1) = kr.

__

Other sequences

Suppose you're given the quadratic sequence ...

  a(n) = pn^2 +qn +r

Since the sequence is known to be quadratic (polynomial degree 2), we expect that we will only need the two previous terms a(n-1) and a(n-2). Effectively, we want to solve ...

  a(n) = c·a(n-1) +d·a(n-2) +e

for the values c, d, and e. Doing that, we find ...

  (c, d, e) = (2, -1, 2p)

So, the recursive relation is ...

  a(1) = p +q +r

  a(2) = 4p +2q +r

  a(n) = 2a(n-1) -a(n-2) +2p

__

Additional comment

The basic idea is to write the expression for a(n) in terms of terms a(n-1), a(n-2) and so on. That will be easier for polynomial sequences than for sequences of arbitrary form.

There are some known translations between explicit and recursive formulas for different kinds of sequences, as we have shown above. If you recognize the sequence you have as being of a form with a known translation, then you would make use of that known translation. (For example, Fibonacci-like sequences are originally defined as recursive, but have explicit formulas of a somewhat complicated nature. If you recognize the form, translation from the explicit formula may be easy. If you must derive the recursive relation from the explicit formula, you may be in for a lot of work.)

750-300= $450 left that needs to be save to meet her goal.

set an equation to equal 450 that includes the next part of the information given which is $12 and hour

A family's home is currently worth $1,553,426, which is 70% higher than the home was
worth when they bought it. What was the value of the home when they bought it?

Answers

Answer:

The value of home when bought was $913,780.

Step-by-step explanation:

Given that:

Current worth of the house = $1,553,426

This is 70% more than the original worth of the house.

Let,

100 be the original percent and x be the original worth

Percent increase = (100+70)% = 170%

170% of x = $1,553,426

[tex]\frac{170}{100}x=1553426[/tex]

1.7x = 1553426

Dividing both sides by 1.7

[tex]\frac{1.7x}{1.7}=\frac{1553426}{1.7}\\x= 913780[/tex]

Hence,

The value of home when bought was $913,780.
