*7. Admission to a museum is $8.20 per adult and $4.10 per child. The expression
8.2a + 4.1c represents the total cost in dollars for admission for a adults and a
children
A group of friends, consisting of 6 adults and 6 children attend the museum. One of
the adults has a coupon for one free adult admission and one child's admission at half
price. What is the total cost for the whole group to enter the museum?
Answer:
$63.55
Step-by-step explanation:
if one of the adults has a free coupon for adult admission, then we have 5 adults
8.20 x 5 = $41
We have 6 children and one with half pay
= (5 x 4.1) + (4.1/2 )
= 20.5 + 2.05
=$22.55
41 + 22.55 = $63.55

An ice chest contains 2 bottles of orange juice,
5 bottles of grape juice, and 1 bottle of apple
juice, all buried in ice. What's the probability
of pulling out a bottle of orange juice and then
a bottle of grape juice?
Answer:
5/28
Step-by-step explanation:
P(oj, then grape) = 2/8 x 5/7 = 10/56 = 5/28
The probability of pulling out a bottle of orange juice and then a bottle of grape juice is 5/28.
What is probability?Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favorable outcomes / Number of sample
An ice chest contains 2 bottles of orange juice, 5 bottles of grape juice, and 1 bottle of apple juice, all buried in ice.
The probability of pulling out a bottle of orange juice and then a bottle of grape juice is calculated as below:-
Probability = Number of favorable outcomes / Number of sample
P(orange , then grape) = 2/8 x 5/7 = 10/56 = 5/28
Therefore, the probability of pulling out a bottle of orange juice and then a bottle of grape juice is 5/28.

Jose desea que la puerta de su cuarto solo se pueda abrir hasta cierta posicion (ver figura). Si uno de los angulos de la abertura mide (x + 5)° y la otra (2x + 13)°. Cual seria la medida del angulo de la abertura menor?
Answer:
La medida del ángulo de la abertura menor es 29°.
Step-by-step explanation:
Podemos calcular la medida del angulo de la abertura menor hallando el valor de "x" en la siguiente ecuación:
[tex] (x + 5) + (2x + 13) = 90 [/tex] (1)
Dado que en la figura podemos observar que la suma de ambos ángulos de abertura resulta en un ángulo rectángulo.
Al resolver la ecuación (1) tenemos:
[tex] x + 2x = 90 - 13 - 5 [/tex]
[tex] 3x = 72 [/tex]
[tex] x = 24 [/tex]
Ahora, podemos encontrar los ángulos de abertura.
Angulo de abertura menor:
[tex] x + 5 = 24 + 5 = 29^{\circ} [/tex]
Angulo de abertura mayor:
[tex] 2x + 13 = 2*24 + 13 = 61^{\circ} [/tex]
Por lo tanto, la medida del ángulo de la abertura menor es 29°.

The length of an equilateral triangle is increased by 5 cm. The perimeter of the new triangle is 72 cm. What is the side length of the original triangle?
Answer:
19cm
Step-by-step explanation:
An equilateral triangle is a triangle where the length of the 3 sides are the same.
the perimeter is the sum of the 3 sides
for example, if the length of the side of the an equilateral triangle is 5, the perimeter is 5 x 3 = 15
let x = unknown length of side
length after increase = x + 5
(x + 5) x 3 = 72
divide both sides of the equation by 3
x + 5 = 24
subtract 5 from both sides of the equation
x = 24 - 5 = 19cm

A tepee is designed to have a diameter of 10 feet and the volume of 419 ft.³ at what height the support poles crossed with some of the tepee correctly?
Answer:
The required height is equal to 5.33 feet.
Step-by-step explanation:
Given that,
Diameter, d = 10 feet
Volume, V = 419 ft.³
We need to find the height the support poles crossed with some of the tepee correctly. Let the height is h.
The tepee is in the form of a cylinder. The volume of a cylinder is given by :
[tex]V=\pi r^2 h\\\\h=\dfrac{V}{\pi r^2}\\\\h=\dfrac{419}{3.14\times 5^2}\\\\h=5.33\ ft[/tex]
So, the required height is equal to 5.33 feet.

Answer:
The Area of Δ ABC = 219.13
Step-by-step explanation:
The hard part about this problem is finding the area without the height
The formula to do this is Area = [tex]\sqrt{S(S-A)(S-B)(S-C)}[/tex]
A, B, C represent the sides
S represents [tex]\frac{1}{2}[/tex] (A + B + C)
In this equation, we will make the base be A, and the other two sides will be B and C
Sides B and C are the same length because they meet at a 90° angle
Lets plug the numbers into the variables
A = 28
B= 21
C= 21
Remember: S represents [tex]\frac{1}{2}[/tex] (A + B + C)
S = [tex]\frac{1}{2}[/tex] (28 + 21 + 21)
S = [tex]\frac{1}{2}[/tex] (70)
S = 35
Lets plug the numbers into the Area Formula now!
Area = [tex]\sqrt{35(35 - 28)(35 - 21)(35 - 21)}[/tex]
According to the order of operations, we need to do the calculations in parentheses first
35 - 28 = 7
35 - 21 = 14
35 - 21 = 14
14 x 14 x 7 = 1372
1372 x 35 = 48020
[tex]\sqrt{48020}[/tex] = 219.13
The Area of Δ ABC = 219.13

X Plus 2/4 equals 20
math help pls i don’t understand how to solve this
===================================================
Explanation:
f(x) = x^3 - 2x + 3
f ' (x) = 3x^2 - 2 ..... apply the power rule
f ' (1) = 3(1)^2 - 2 ... plug in x coordinate of given point
f ' (1) = 1
If x = 1 is plugged into the derivative function, then we get the output 1. This means the slope of the tangent line at (1,2) is m = 1. It's just a coincidence that the x input value is the same as the slope m value.
Now apply point slope form to find the equation of the tangent line
y - y1 = m(x - x1)
y - 2 = 1(x - 1)
y - 2 = x - 1
y = x - 1 + 2
y = x + 1 is the equation of the tangent line.

A streaming video service administers a survey through its platform to evaluate the variety of options provided through the service. This is one of the questions on the survey.
Rate the variety of material available through our service on a scale of 1 to 4 stars, with 4 being the highest.

Which of these could affect the results of the survey?
A.
The survey is biased because it was administered through the service instead of in person.
B.
The survey is biased because it is being taken only by the service’s users.

Answer:
The answer for you here is D.

A. makes no sense, I don't think I need to explain myself there lol.
B. and C. both pretty much say the same thing, since you can only pick one that makes those answers sketchy. Not to mention, if anything it would be MORE biased for the survey to allow people who don't even use the service to vote.
D. This one simply makes the most sense, as that is indeed something that varies greatly from person to person. (Also I got this one right on the test :P )
The option that could affect the results of the survey is the answer options could be interpreted differently by different users.
What can affect the results of the survey?The survey is meant to be taken only by those who use the service. The fact that the survey administered through the service instead of in person does not make the survey biased.
The question is too ambiguous and it can be interpreted differently by the users.

Gas prices are projected to increase 124% by April. A gallon of gas currently costs $3.17. What is the
projected cost of a gallon of gas in April?
Answer: $7.1
Step-by-step explanation:
Since the gallon of gas currently costs $3.17 and the prices are projected to increase 124% by April. Then, the projected cost of a gallon of gas in April will be:
= $3.17 × (100% + 124%)
= $3.17 × 224%
= $3.17 × 2.24
= $7.1
Therefore, the projected cost will be $7.1

What is the volume of the square pyramid?
Answer:
V = 621.4 mm^3
Step-by-step explanation:
The volume of this pyramid is V = (1/3)(base area)(height). We must calculate the height from the info given. Draw in a vertical line to represent the height. Imagine a triangle with hypotenuse 12.8 mm (given) and shorter leg (13 mm)/2, or 6.5 mm.
The Pythagorean Theorem applies here: h^2 + (6.5 mm)^2 = (12.8 mm)^2. We get: h^2 + 42.25 = 163.84, or h^2 = 121.59, or h = √121.59, or
h = 11.03 mm.
Then, as before, the volume of this prism is V = (1/3)(base area)(height), or with specific numerical values V = (1/3)(13 mm)^2(11.03 m), or
V = 621.4 mm^3
