Need help ASAP!!!! Been thinking for a long time.
Answer:
81%
Step-by-step explanation:
First, let's set up 3 equations:
w*0.6 = x
x*1.5=y
y*0.9=z
Now, we can substitute x in the second equation for w*0.6:
w*0.6*1.5 = y
Lastly, we can substitute y in the last equation for w*0.6*1.5:
w*0.6*1.5*0.9=z
w*0.81=z
Therefore, z is 81 percent of w.
JC has a VIP membership to a movie theater, so she pays $27 a year and six dollars for each movie she sees. Claire doesn't have a membership, so she pays $8.25 each movie she sees. How many movies would they have to see in a year in order to pay the same amount that year.
Answer:
12 movies
Step-by-step explanation:
Given
VIP
[tex]Base\ Amount = \$27[/tex]
[tex]Per\ movie = \$6[/tex]
Regular
[tex]Per\ movie = \$8.25[/tex]
Required
Determine the number of movies where they pay the same amount
Represent the number of movies with m.
For VIP, we have..
[tex]Expression = 27 + 6 * m[/tex]
[tex]Expression = 27 + 6m[/tex]
For regular, we have
[tex]Expression = 8.25 * m[/tex]
[tex]Expression = 8.25m[/tex]
Equate both expressions
[tex]8.25m = 27 + 6m[/tex]
Collect Like Terms
[tex]8.25m - 6m = 27[/tex]
[tex]2.25m = 27[/tex]
Solve for m
[tex]m = 27/2.25[/tex]
[tex]m = 12[/tex]

Let Q(t) represent the total number of boxes, and t is the time since noon in hours.
A warehouse contains 55 boxes, hence b = 55. At 3:30 pm (3.5 hours), the warehouse contains 90 boxes.

If you add 10 grams of sugar into 30 grams of 20 % sugar syrup, you will make ____ grams of ____% sugar syrup.
Answer:
40 grams of 40% sugar syrup
Step-by-step explanation:
20% of 30 grams = 6grams of sugar
6 grams + 10 grams = 16 grams of 40% instead of 30 now
Therefore, 40g----------100%
16g-----------40%
Answer:
40 grams of 40% sugar syrup
Step-by-step explanation:
40 grams of 40% sugar syrup
30+10== 40 g
20% sugar in 30 = 1/5 of the syrup is sugar. = 6 g of sugar
6+10 = 16g of sugar in 40 grams of syrup.
16/40=x/100

Porfavor para hoy dice el papa de Rafael va a construir una picina afuera de su casa en forma de cuadrado en el area de 121 pies cuadradas. Alrededor de la picina quiere construir una plataforma de cuatro pies de ancho, Explicale a Rafael paso apaso como calcular el perimetro de la plataforma, Despues me dice que explique paso a paso en mis propias palabras como calcular el perimetro de la plataforma
Answer:
Deducir ecuación de área del cuadrado/Despejar y calcular longitud de lado/Deducir ecuación de perímetro/Calcular perímetro del cuadrado.
Perímetro: 44 pies cuadrados.
Step-by-step explanation:
Podemos explicarle al papa de Rafael lo siguiente:
Estimado señor.
Una piscina de forma cuadrada tiene la forma de un cuadrilátero con cuatro lados iguales y cuatro ángulos rectos en sus vértices. El área del cuadrado es igual a la longitud de cualquiera de sus lados multiplicada por si misma. Es decir:
[tex]A = l\cdot l = l^{2}[/tex] (Eq. 1)
Entonces, la longitud de cualquiera de sus lados es la raíz cuadrada del área de su piscina. Es decir:
[tex]l =\sqrt{A}[/tex] (Eq. 1b)
Donde [tex]l[/tex] y [tex]A[/tex] son la longitud de lado y el área de la piscina, medidos en pies y pies cuadrados, respectivamente.
Si sabemos que su piscina tiene un área de 121 pies cuadrados ([tex]A = 121\,ft^{2}[/tex]), entonces la longitud del lado de piscina es:
[tex]l = \sqrt{121\,ft^{2}}[/tex]
[tex]l = 11\,ft[/tex]
Tenemos que la longitud del lado es 11 pies.
Ahora, el perímetro es la suma de las longitudes de los lados del cuadrado. Si el cuadrado tiene 4 lados de igual medida, entonces el perímetro del cuadrado es igual a cuatro veces esa longitud. Esto es:
[tex]p = 4\cdot l[/tex] (Eq. 2)
Donde [tex]p[/tex] es el perímetro, medido en pies.
Si conocemos que la longitud del lado es 11 pies ([tex]l = 11\,ft[/tex]). En consecuencia, encontramos que el perímetro de su piscina es:
[tex]p = 4\cdot (11\,ft)[/tex]
[tex]p = 44\,ft[/tex]
El perímetro de su piscina es de 44 pies.

Determine the equation of the Logarithmic Regression that models the data. Then use your equation to determine the amount of sunlight (%) that penetrates to a depth of
150m. Express you answer to the nearest hundredth of a percent
Answer:
Percentage of light that penetrates at 150 m will be 0.94%.
Step-by-step explanation:
By using logarithmic regression calculator,
Equation of the regression line will be,
y = 104.5173 - 20.6711(lnx)
Where x represents the depth of the ocean
And y will represent the penetration of light
Therefore, at the depth of 150 m, penetration of the light will be,
y = 104.5173 - 20.6711[ln(150)]
= 104.5173 - 103.5753
= 0.9420
≈ 0.94 %
Therefore, percentage of light that penetrates at 150 m will be 0.94%.

Step-by-step explanation:
Carla wanted to buy a new guitar. Carla deposited $200.00 into a new savings account that
earns interest compounded continuously. After 1 year, she withdrew the entire balance of
$231.00 and bought the guitar. What was the interest rate on the account?
Round your answer to the nearest tenth of a percent.
Answer:
%15.5
Step-by-step explanation:
200+(200x)=231
*x is the interest rate
so let's break down this question by going backwards. we can subract 200 from both sides since we cann easily get rid of +200. so you would get:
200x= 31
Now divide both sides by 200 to eliminate anything else, just to keep x alone.
x= 0.155
and a percent it would be %15.5
and to check:
200+(200*0.155)= 231
Solve for x.

Train A leaves New York for California at the same time Train B leaves California for New York. They are 2900 miles apart. They both travel at an average speed of 120 mph. A. What is the velocity of train A? B. What is the velocity of train B? C. How long will it take before they meet? Show your work.
Answer:
(A) 120 mph
(B) -120 mph
(C) 12 hours 5 minutes.
Step-by-step explanation:
Given that,
New York and California are 2900 miles apart,
Both the trains A as well as B travel at an average speed of 120 mph.
Assuming that the path between the starting point in New York and the ending point in California is straight, so the given distance of 2900 miles is actually the shortest distance which is the displacement between the source and destination.
So, the given speed on the straight path is actually the velocity.
Assuming that the velocity is positive in the direction from New York towards California.
(A) So, the velocity of train A (towards California) = 120 mph.
(B) The velocity of train B (towards New York) = -120 mph.
(C) Bothy are moving towards each other, so the relative velocity between them is 120+120=240 mph, and the initial distance between them is 2900 miles.
When they meet, the displacement between them becomes zero, displacement covered= 2900-0=2900 miles.
So, the time, t, taken to cover the displacement 2900 miles with a relative velocity of 240 mph is
[tex]t=\frac{2900}{240}[/tex] [as time= displacement / relative velocity]
[tex]\Rightarrow t=12\frac{1}{12}[/tex] hours
=12 hours 5 minutes.
Which represents the distance between A(2, 3) and B(-1,-1)?
Answer:
5 units
Step-by-step explanation:
(x1, y1) =A(2,3)
(x2,y2) =B(-1,-1)
Using distance formula,
AB^2 = (x2-x1) ^2 +(y2-y1) ^2
=(-1-2)^2 +(-1-3)^2
=9+16
=25
Therefore, AB=5 units

Answer: (3)
Step-by-step explanation:
Points X and Z are on a number line, and point Y partitions line XZ into two parts so that the ratio of the length of line segment XY to the length of line segment YZ is 1:4. The coordinate of X is 1.3, and the coordinate of Y is 3.8. What is the coordinate of Z?
Answer:
13.8Step-by-step explanation:
if Points X and Z are on a number line and point Y partition line XZ into two parts where XY: YZ = 1:4, this can be expressed as;
XY/YZ = 1/4
cross multiply;
YZ = 4XY
Also, if The coordinate of X is 1.3, and the coordinate of Y is 3.8, then the distance XY will be expressed as XY = 3.8 - 1.3
XY = 2.5
YZ = 4(2.5)
YZ = 10
Since Y is at 3.8 and YZ is 10, then coordinate Z will be YZ + Y
coordinate of Z = 10+3.8
coordinate of Z = 13.8
