Swimming Pool On a certain hot summer's day, 492 people used the public swimming pool. The daily prices are $1.50 for children and $2.50 for adults. The receipts for admission totaled $1060.00. How many children and how many adults swam at the public pool that day?
There were ______ children at the public pool.
Answer:
# of children = 170, # of Adults = 492 - 170 = 322
Step-by-step explanation:
Define C and A as
C = # of children
A = # of adults
Then,
A + C = 492
1.5C + 2.5A = 1060, so that
1.5C + 2.5(492 - C) = 1060
1.5C + 1230 - 2.5C = 1060
-C = 1060 - 1230
C = 170
Patty is ordering vests for her scout troop to wear in the Veterans Day parade. She ordered 12 vests from the Festive Features clothing shop. Since this was a bulk order, Festive Features reduced the price of each vest by $6. The total came to $132. Which equation can you use to find the amount, v, Festive Features normally charges for a vest?
Algebraic equations are equations that have coefficients and unknown variables in them.
The equation that you can use to find the amount "v" Festive features normally charges for a vest is: 12(v - 6) = 132
The current cost per vest was v - $6
Where v = Initial cost of the vest
The total cost of 12 vests after price reduction was:
$132.
Hence, our equation is given as:
$132 = 12(v - $6)
12(v - 6) = 132
$132 = 12v - 72
Add 72 to both sides
$132 + 72 = 12V
204 = 12v
v = 204/12
v = $17
Thus: The amount v, Festive Features normally charges for a vest is $17
Therefore, the equation to find the amount Festive Features normally charges for a vest is 12(v - 6) = 132

Step-by-step explanation:
Use the Pythagorean Theorem to find the missing sides in the triangles.
[tex]c^{2}[/tex] = [tex]a^{2}[/tex] + [tex]b^{2}[/tex]
Q2. [tex]c^{2}[/tex] = 8^2 + 40^2
[tex]c^{2}[/tex] = 1664
c = [tex]\sqrt{1664}[/tex]

Miss Hawaii
find the area of a square whose side length is (7a^2b^3)
The area of a square whose side length is (7a^2b^3) is 49a^4b^6
The formula for calculating the area of a square is expressed as:
A = L^2
L is the side length of the square
Given the following parameter
L = 7a^2b^3
Get the area of the square
A = (7a^2b^3)^2
A = 7^2 * a^4 * b^6
A = 49a^4b^6
Hence the area of a square whose side length is (7a^2b^3) is 49a^4b^6

What is the slope of the line shown on the grid?
Answer:
Answer is last option, -3.
Step-by-step explanation:
We know it's going to be a negative slope because the line is going down to the right, so it can't be eighther option 1 or 3.
Next it appears the line is going 3 units down and 1 unit to the right. So it will be written as -3/1 because of rise/run.
Hope this helps/makes sense :)
crecimiento de arboles
un vivero de plantas verdes suele vender cierto arbusto despues de 6 años de crecimiento y cuidado. La velocidad de crecimiento durante esos 6 años es aproximadamente dh/dt = 1.5t + 5, donde t es el tiempo en años y h es la altura en centimetros. Las plantas de semillero miden 12 centimetros de altura cuando se plantan (t=0).
determinar la altura despues de t años
que altura tiene los arbustos cuando se venden
Queremos encontrar la altura de las plantas luego de t años, dado que conocemos la altura inicial y la velocidad de crecimiento.
La ecuación de la altura es:
[tex]h(t) = 0.75*t^2 + 5*t + 12[/tex]
Con ella veremos que los arbustos miden 69cm cuando son vendidos.
Veamos como resolver esto.
h(t) es la función que modela la altura de las plantas.
Sabemos que:
[tex]\frac{dh(t)}{dt} = 1.5*t + 5[/tex]
Sí integramos, obtendremos:
[tex]h(t) = (1/2)*1.5*t^2 + 5*t + c[/tex]
donde C es una constante de integración, la cual representa la altura inicial (para t = 0) de las plantas, notar que:
[tex]h(0) = c[/tex]
Y sabemos que las plantas miden 12 cm cuando son plantadas, entonces c = 12.
La ecuación de la altura es entonces:
[tex]h(t) = 0.75*t^2 + 5*t + 12[/tex]
Esta ecuación nos da la altura en centimetros a tiempo t.
Sabemos que los arbustos se venden luego de 6 años, entonces la altura que tendran cuando son vendidos es:
[tex]h(6) = 0.75*6^2 + 5*6 + 12 = 69[/tex]
Es decir, los arbustos miden 69cm cuando son vendidos.

Answer:
A, C
Step-by-step explanation:
First of all, recognize that any basic arithmetic operation between a rational number and an irrational number will have an irrational result. That means, you can eliminate any answer choices that involve an irrational number.
Fractions and mixed numbers involving integers are always rational, so you only need to look at the radicals. You know 9 is 3×3, so is a perfect square, and √9 = 3 is rational. You know 5 is not a perfect square, so √5 is irrational.
Considering the above, any expression involving √5 will have an irrational result. That means you can eliminate choices B and D.
choices A and C will result in a rational number
_____
Additional comment
A = 6.8 +0.75 = 7.55 (rational)
C = 6.8 × 0.75 = 5.100 (rational)
