Mateo compró un artefacto gastando los 3/7 de su dinero, quedándole 360 soles, ¿Cuál era el dinero que tenía Mateo al inicio?

Answers

Answer 1

Answer:

840 soles

Step-by-step explanation:

Sea la cantidad de dinero que Mateo tenía al principio = x

Mateo compró un artefacto gastando 3/7 de su dinero, dejándole 360 ​​soles,

Por eso,

3/7 × x = 360 soles

3x / 7 = 360 soles

Multiplicar cruzada

3x = 7 × 360 soles

x = 7 × 360 soles / 3

x = 840 soles

Por tanto, el dinero que tenía Mateo al principio es de 840 soles

Answers

It should be A. Hope this helps.

Answer:

x^3-4

Step-by-step explanation:

y = (x+4) ^ 1/3

Exchange x and y

x = (y+4)^1/3

Solve for y

Raise each side to the 3rd power

x^3 =  (y+4)^1/3 ^3

x^3 = y+4

Subtract 4 from each side

x^3 -4 = y+4-4

x^3 -4 = y

The inverse is

Joan works on commission for a furniture store. She gets a base pay of $80 a day plus 4 percent of the value of any merchandise she sells that exceeds a total of $400. Joan wrote the expression 400 + 0.04(t − 80), where t represents her sales total in dollars, to compute the total amount of money that she will make. For sales of $500 Joan calculated that she will make $416.80. Explain Joan's error by completing the correct expression and how much she will make.

Answers

Answer:

Total amount earned = $84

Step-by-step explanation:

The correct expression is

Total amount earned = 80 + 4% of (t - 400)

= 80 + 0.04(t - 400)

where,

t = her sales total in dollars

Total amount of money that she will make for sales of $500

Total amount earned = 80 + 0.04(t - 400)

= 80 + 0.04(500 - 400)

= 80 + 0.04(100)

= 80 + 4

= 84

Total amount earned = $84

Please help!!!! There are 324 students coming.

Answers

Answer:     $1,314.40

===============================================================

Explanation:

Assuming there are 324 seats available for the 324 students, this means that 324*5.60 = 1,814.40 dollars is earned in revenue from ticket sales.

Let x be the cost of equipment, lighting, and costumes combined.

The expression 1814.40 - x represents the profit made. It's the amount of money left after the bills are paid, so to speak. Or you could say profit = revenue - cost.

The committee wants $500 remaining, so they want 1814.40 - x to be equal to 500.

Let's solve for x

1814.40 - x = 500

-x = 500-1814.40

-x = -1314.40

x = 1314.40

So if $1,314.40 is spent on equipment, lighting, and costumes combined, then the committee will have $500 left over. If they spend less on those items, then the profit is more than $500. This means that $1,314.40 is the most they can spend.

Answers

Answer:  

Part (a) Vertex = (-3, -1)Part (b) Vertex = (4, 5)Part (c) function 2; max value = 5

=====================================================

Explanations:

Part (a)

In this case, the vertex is the highest point, so the vertex of function 1 is (-3, -1)

If the parabola was flipped so that it opened upward, instead of downward, then the vertex would be the lowest point.

----------------------------

Part (b)

We could graph this function to see where the highest or lowest point is, but there's another way we could find the vertex using algebra.

The given equation is in the form y = ax^2 + bx + c where in this case

a = -2b = 16c = -27

The a and b values are plugged into the formula below to get

h = -b/(2a)

h = -16/(2*(-2))

h = -16/(-4)

h = 4

This is the x coordinate the vertex since the vertex is (h,k)

To find k, we plug that value of h into the original function to find its corresponding y value.

y = -2x^2 + 16x - 27

y = -2(4)^2 + 16(4) - 27

y = -2(16) + 16(4) - 27

y = -32 + 64 - 27

y = 5

We found that h = 4 leads to k = 5. The vertex is (h,k) = (4, 5)

----------------------------

Part (c)

We'll compare the y values of each vertex

Function 1 has a vertex of (-3, 1)Function 2 has a vertex of (4, 5)

The vertex with the larger y value is the winner, so that would be function 2. This parabola reaches a higher peak compared to the other curve.

The max value here is y = 5. In other words, it's the maximum output the function can produce.

If you graphed functions 1 and 2 together on the same xy grid (see below), you'll see that the curve for function 2 reaches a higher peak.

What is Area?

Area is a collection of two - dimensional points enclosed by a single dimensional line. Mathematically, we can write -

V = ∫∫F(x, y) dx dy

Given is a circle whose radius is equivalent to 1 units.

It is asked to find the circumferance of the circle given in the formula.

We know that the circumferance of the circle is given by the formula -

C = 2πr

Putting the values, we get -

C = 2 x π x 1

C = 2π units

So, it can be concluded that the circumferance of the circle given is 2π units.

Therefore, the circumferance of the circle given is 2π units.

Nancy is making accessories for the soccer team. She uses 542.43 inches of fabric on headbands for 37 players and 4 coaches. She also uses 314.87 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?

Answers

Answer:

21.74 inches of fabrics

Step-by-step explanation:

Headbands = 542.43 inches of fabric

37 players + 4 coaches = 41 people

Each person uses = 542.43 inches of fabric / 41 people

= 13.23 inches of fabrics for headband per person

wristbands = 314.87 inches of fabric

Players = 37

Each person uses = 314.87 inches of fabric / 37 players

= 8.51 inches of fabrics for wristband per person

How much fabric was used on a headband and wristband for each player?

Fabrics used on a headband and wristband for each player = 13.23 inches of fabrics for headband per person + 8.51 inches of fabrics for wristband per person

= 13.23 inches+ 8.51 inches

= 21.74 inches

Fabrics used on a headband and wristband for each player = 21.74 inches of fabrics

Answers

Answer: B) Not enough info

While both arcs have the same degree measure (140 degrees), we don't have enough information about the radii. If the radius AO is the same length as radius OH, then the arcs are congruent. Otherwise, the arcs aren't congruent.

No, the arcs aren't congruent because the we don't know the size of both the circles, it is possible that one circle would be small and the other would have greater size than the first one, they only have same measure(140°) but not same size.

Step-by-step explanation:

Price of photograph = 60000 = 100%

Tax = x dollars = 13% of 60000

100% + 13% = 113% = 1.13

Multiply

1.13(60000) = 67800

To check, lets find 13% of 60000 and add to 60000

13% = 0.13

0.13(60000) = 7800

Answers

Answer:

The interval [25, 35] has the slowest average rate of decay.

Step-by-step explanation:

The number of grams in a sample of radium is represented by the function [tex]r(t) = 50\cdot e^{-0.013\cdot t}[/tex], which is a monotonous decreasing function. Hence, the greater the values of [tex]t[/tex], the slowest the average rate of decay, represented by a secant line. The interval [25, 35] has the slowest average rate of decay.
