Answer:
32 times
Step-by-step explanation:
If you can go around 54 times for $12, then you multiply the amount of money you pay by four to get the number of times you can go around the track.
Hope this helps! Please mark Brainliest!
Answer:
I would say 36 because 54 times 8 is 432 and if you divide that by 12 you get 36.

Es un juego de futbol de salon se vendieron 12000 boletos. El precio de los boletos es de $25.00 en la seccion numerada y $15.00 en la general. Si el ingreso total que se obtuvo fue de $220.000.00 ¿cuantos boletos se vendieron de la seccion numerada?
Answers
Answer:
La cantidad de boletos vendidos en la sección numerada = x = 4000 boletos
El número de entradas vendidas en la sección general = y = 8000 boletos
Step-by-step explanation:
Deje que el número de boletos vendidos en la sección numerada = x
Sea el número de boletos vendidos en la sección general = y
Es un partido de fútbol sala se vendieron 12.000 entradas.
x + y = 12000.… ..... Ecuación 1
x = 12000 - y
El precio de las entradas es de $ 25.00 en la sección numerada y $ 15.00 en la general. Si el ingreso total obtenido fue de $ 220,000.00,
$ 25 × x + $ 15 × y = $ 220 000
25x + 15y = 220.000 ..... Ecuación 2
Sustituya x por 12000 - y en la ecuación 2
25 (12 000 - años) + 15 años = 220 000
300000 - 25 años + 15 años = 220 000
300000 - 220000 = 25 años - 15 años
80000 = 10 años
y = 80000/10
y = 8000 boletos
x = 12000 - y
x = 12000 - 8000
x = 4000 boletos
La cantidad de boletos vendidos en la sección numerada = x = 4000 boletos
El número de entradas vendidas en la sección general = y = 8000 boletos
Responder:
8000
Explicación paso a paso:
Dado que las entradas:
Sección numerada = $ 25
Sección general = $ 15
Ingreso tital = 220.000
Número de entradas vendidas = 12000
Deje el boleto vendido de la sección numerada = n
Número vendido de la sección General = g
n + g = 12000
25n + 15g = 220.000
n = 12000 - g
25 (12000 g) + 15 g = 220000
300.000 - 25g + 15g = 220000
-10g = 220000 - 300000
-10g = - 80000
g = 8000
n = 12000 - g
n = 12000 - 8000
n = 4000
Entradas vendidas de la sección General = 8000
The location P(t) of an object moving in the xy-plane at time t seconds is given by the equations P(t)=(x(t),y(t)), where x(t)=a +3t and y(t)=b +8t, a,b are constants and distances are measured in units of meters. The equations x(t), y(t) describe linear parametrized motion; see section 10.1 of the textbook for review.
(h) The line along which the object is moving in the plane has the equation: y=___x+___.
(i) Let d(t) be the distance the object has traveled after t seconds. The formula for d(t) is:
(j) The instantaneous rate of change of d(t) at time t is:
Answers
Answer:
(h) y = -8/3·x + 16·a/3
(i) dt = √(x² + y²) = √( (a + 3·t)² + (b + 8·t)²)
(j) [tex]\dfrac{d(t)}{dt} = \dfrac{3\cdot a +8\cdot b+ 73 \cdot t}{\sqrt{a^2 + 6\cdot a \cdot t + b^2+16 \cdot b \cdot t + 73\cdot t} }[/tex]
Step-by-step explanation:
(h) The location of the object = P(t) = (x(t), y(t))
Where;
x(t) = a + 3·t
y(t) = b + 8·t
Therefore we have;
At x = 0, t = -a/3. at y = 0, b = -8·t = -8·a/3
y = -8·a/3 + 8·t = -8/3(a - 3·t) = -8/3(x - 2·a) = -8/3·x + 16·a/3
y = -8/3·x + 16·a/3
(i) dt = √(x² + y²) = √( (a + 3·t)² + (b + 8·t)²)
(j) The instantaneous rate of change of d(t), with a corresponding change in time, t, obtained by solving through an online platform, is given as follows;
[tex]\dfrac{d(t)}{dt} = \dfrac{d}{dt} \left (\sqrt{\left (a + 3\cdot t \right)^2 + \left (b + 8\cdot t \right)^2} \right ) = \dfrac{3\cdot a +8\cdot b+ 73 \cdot t}{\sqrt{a^2 + 6\cdot a \cdot t + b^2+16 \cdot b \cdot t + 73\cdot t} }[/tex].
Reasoning: Kiera and Javier are grouping equations based
on the number of operations needed to solve them. In
order to solve the equation -4(-9 + x) = 57, Kiera
says that you need three operations. Javier says you
need two operations. Their teacher says that they are
both correct. Which operations do you need to use to
solve the equation in three operations? Use a pencil
and paper. Explain how you can use two operations to
solve the equation. Which method do you prefer?
Why?
Answers
Answer:
Step-by-step explanation:
Given the -4(-9 + x) = 57, to solve this equation, follow the following steps:
Expend the parentheses at the left hand side using the distributive law.
-4(-9)+(-4x) = 57
Open the bracket by multiplying
+36-4x= 57
Subtract 36 from both sides
36-4x-36 = 57-36
-4x = 21
Divide both sides by -4
-4x/-4 = 21/-4
x = -21/4
From the calculation, we can see that we used 3 operations (multiplication, subtraction and division operations)
The most preferred is multiplication operation because the operation helps to simplify the parentheses using the distributive law in step 1.
The regular price of a scooter is $65.50. It is on sale for $52.40. What is the percent
decrease from the regular price to the sale price of the scooter?
Answers
Answer:
20%
Step-by-step explanation:
First we find the actual dollar amount of the discount.
$65.50 - $52.40 = $13.10
Now we need to find what percent of $65.50 is $13.10.
To find what percent a part is of the whole, divide the part by the whole and multiply by 100%.
percent = part/whole * 100%
percent = $13.10/$65.50 * 100% = 20%
Answer: 20%
Answer:
20%

HINT: total worth= investment amount (1.05)^t
A: t= $7,739.05 ($5,500)^ 0.05
B: $7,739.05= $5,500 (1.05) ^t

PLEASE EXPLAIN HOW YOU GOT THE ANSWER
Answers
Answer:
T = 5.79 (approximated)
Step-by-step explanation:
Using I = PRT/100
where P = The principal amount invested = $5500
R = Rate of Interest =5%
T = Time (in years)
I = Interest = $7,739.05 - $5500 = $2239.05
Substituting the above values in the formula
I = PRT/100 becomes
2239.05 = 7,739.05 * 5 * t / 100 -------- Multiply 100 to both sides
2239.05 * 100 = 100 * 7739.05 * 5 * t / 100
223905 = 7739.05 * 5 * t
223905 = 38695.25t
Divide both sides by 38695.25t
223905/38695.25 = t
5.786369 = t
T = 5.79 (approximated)

When a coordinate grid is superimposed on a map of lanesville the middle school is located at (15,13) and the librart is located at (27,9). If each unit represents 1 mile how many miles apart are the middle school in the liebrary round your answer to the nearest 10th
Answers
Answer:
4.5 miles
Step-by-step explanation:
Given
[tex]Middle\ School = (15,13)[/tex]
[tex]Library = (27,9)[/tex]
To solve this, we simply solve for the distance (D) between both points.
[tex]D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
Where:
[tex](x_1,y_1) = (15,13)[/tex]
[tex](x_2,y_2) = (27,9)[/tex]
[tex]D = \sqrt{(27 - 25)^2 + (9 - 13)^2}[/tex]
[tex]D = \sqrt{(2)^2 + (-4)^2}[/tex]
[tex]D = \sqrt{4 + 16}[/tex]
[tex]D = \sqrt{20}[/tex]
[tex]D=4.472135955[/tex]
[tex]D=4.5[/tex] --- approximated
Since each unit is 1 mile. The distance is 4.5 miles

Answer:
4) t -3
Step-by-step explanation:
-16t² = -16 * t * t

Which of the following is an arithmetic sequence?

2, 4, 8, 16, ...
-8, -6, -4, -2, ...
Answers
Answer:
-8, -6, -4, -2
Step-by-step explanation:
This is the only sequence that is using constant repetition of addition, either adding positive numbers or adding negative numbers (the same positive or negative number). This one that you answered is always adding 2 from the prior number, so -6 = -8+2, -4=-6+2, and so on.
The first one is an odd combo where you add and subtract different values different signs each time, it is not constant addition of the same number.
The second one is multiplication which is not arithmetic, so that means it is constantly being multiplied by 2 each time.
Answer:-8,-6,-4,-2
Step-by-step The last one because it is consistent by adding 2 the other ones ad then subtract or multiply and you can do that so the last on
