The equation that represent each situation, in terms of x, is
A = 19 + 0.50xB = 13 + 1.50xThe number of monthly movies watched, x, that would make the two plans have an equal monthly cost is 6 movies.
How to write and solve equation?Let
Monthly cost of plan A = AMonthly cost of plan B = BNumber of monthly movies watched = xPlan A:
A = 19 + 0.50x
Plan B:
B = 13 + 1.50x
Equate A and B
19 + 0.50x = 13 + 1.50x
collect like terms
19 - 13 = 1.50x - 0.50x
6 = x
Hence,
x = 6 movies
In conclusion, the number of monthly movies watched to have an equal amount is 6 movies.

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Number of rides = m + 5
Number of games = m
Now,
Each game costs $1.50 and each ride costs $5. Isaac spent $44.50 altogether at the carnival.
This means,
1.50m + 5(m + 5) = 44.50
1.50m + 5m + 25 = 44.50
6.50m = 44.50 - 25
m = 19.5/6.50
m = 3
Now,
The number of games = 3.
The number of rides.
= m + 5
= 3 + 5
= 8
Thus,
The number of games is 3.
The number of rides is 8.

A collector's model racecar is scaled so that 1 inch on the model equals 6 1/4 feet on the actual car. If the model is 2/3 inch high, how high is the actual car? explain
Answer:
50 inches, or 4 1/6 feet
Step-by-step explanation:
If one inch is equal to 6 1/4 feet, we can translate this number from feet to inches.
4 1/6 feet = 75 inches.
Now we can take 75 and find out 2/3 of it.
2/3 of 75 is 50.
The answer is 50 inches.
If you want to convert the answer from feet to inches, its simple.
12 × 4 = 48
50 - 48 = 2
2 inches is equal to 1/6 of a foot.
The answer in feet, is 4 1/6 foot.

in January the depth of a lake was 943 feet in August the depth of the lake was 754.4 what is the percentage decrease of the depth of the lake from January to August
The percentage decrease of the depth of the lake from January to August is 20%.
What is percentage decrease?The difference between the initial and final numbers is shown as a percentage reduction. It displays a percentage loss of value compared to the original regardless of the units. The decrease is equal to the initial amount less the final amount.
Given,
The depth of lake in January = 943 feet
The depth of lake in August = 754.4 feet
The difference is = (943-754.4) feet
= 186.6 feet
So, the percentage decrease of the depth of the lake from January to August will be = (186.6 ÷ 943) × 100
= 20%

Round each fraction to 0,1/2, or 1…… 7/12 5/6 2/11 4/9
Answer:
1/2, 1, 0, 1/2
Step-by-step explanation:
We can solve this by rounding each fraction to either 0, 1/2, or 1.
The first fraction, 7/12, is pretty close to 6/12, which is 1/2 of 12.
So we can round this to 1/2.
The second fraction, 5/6, is closer to 6/6 (1) than 3/6 (1/2).
So we can round this to 1.
The third fraction, 2/11 is closer to 0 than 5.5/11 (1/2).
We can round this to 0.
4/9 is closer to 4.5/9 (1/2) than 0.
We can round this to 1/2.
Therefore, when we round all of these fractions, we are left with 1/2, 1, 0, 1/2.
If log₂(4x + 6) = 4, then x = ____
You may enter the exact value or round to 4 decimal places.
Answer: -1/2
Step-by-step explanation: To solve this problem, we can use the properties of logarithms to isolate the variable x on one side of the equation. The properties of logarithms tell us that the logarithm of a product is the sum of the logarithms of the factors, and that the logarithm of a power is the exponent times the logarithm of the base.
If log₂(4x + 6) = 4, we can rewrite the left side of the equation as follows: log₂(4x + 6) = log₂(2^4 * (2x + 3))
Then, using the property of logarithms that the logarithm of a product is the sum of the logarithms of the factors, we can simplify the equation as follows: log₂(4x + 6) = 4 + log₂(2x + 3)
Now, we can use the property of logarithms that the logarithm of a power is the exponent times the logarithm of the base to simplify the equation even further: log₂(4x + 6) = 4 + 1 * log₂(2x + 3)
Since the logarithm of a power is the exponent times the logarithm of the base, this means that the logarithm of a number is the logarithm of that number divided by the logarithm of the base. Therefore, we can divide both sides of the equation by log₂ to isolate the variable x on one side of the equation:
log₂(4x + 6) / log₂ = 4 + 1 * log₂(2x + 3) / log₂
(4x + 6) / 1 = 4 + (2x + 3) / 1
4x + 6 = 4 + 2x + 3
4x + 6 = 2x + 7
2x = -1
x = -1/2
Therefore, if log₂(4x + 6) = 4, then x = -1/2.

There will be 0.48 grams will be left in the sample after 59 years.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
Since we have given that initial sample of 171 g of a radioactive substance decays according to the function
[tex]A(t) = 171e ^ {- 0.04(t) }[/tex]where t is given in years
Here, Initial amount of radioactive substance = 171 grams
We need to find the amount of substance that will be left in the sample after 59 years.
So, t = 59 years
So, it becomes,
[tex]A(t) = 171e ^ {- 0.04(59) }\\\\A(t) = 0.48[/tex]

After 15 minutes the pan will have a temperature of °F.
(Round to the nearest integer.)
After 15 minutes the pan will have a temperature of 36°F
How to determine the temperature of the pan after 15 minutes?
Newton's Law of Cooling, if a body with temperature T₁ is placed in surroundings with temperature To, different from that of T₁, the body will either cool or warm to temperature T(t) after t minutes, where T(t) = T₀ + (T₁-T₀)e^(kt)
Given: T₁ = 120°F, T₀ = 0°F. After 5 minutes, T(t) = 80°F
T(t) = T₀ + (T₁-T₀)e^(kt)
80 = 0 + (120-0)e^(5k)
80 = 120e^5k
e^5k = 80/120
e^5k = 2/3
5k = ln(2/3)
k = ln(2/3) / 5
k = -0.0811
The temperature of the pan after 15 minutes will be:
T(t) = T₀ + (T₁-T₀)e^(kt)
T(15) = 0 + (120-0)e^(-0.0811×15)
T(15) = 120e^(-0.0811×15)
