City A and City B are 312 miles apart. John leaves City B, driving towards City A at an average rate of 70 miles per hour. Pat leaves City A at the same time, driving towards City B in her antique auto, averaging 34 miles per hour. How long will it take them to meet?
Answers
Pat and John will meet in 3 hours.
What is speed?Speed is measured as distance moved over time. The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in metres (m) and time is in seconds (s), so the units will be in metres per second (m/s).
here, we have,
How to calculate the value?
It should be noted that speed = Distance / Time
The appropriate equation will be:
80t + 24t = 312
104t = 312
t = 312/104
t = 3. hours
Therefore, it will take them 3 hours to meet.

The car salesman tells you that for every $2,000 a car costs, your monthly payment goes up by $45. If you are looking at a car that costs $30,000 how much would your monthly payment be? Just place the whole number not the dollar sign.
I will give you 100 points if you answer RIGHT NOW PLEASE :)
Answers
Answer: $675
Step-by-step explanation:
To calculate the monthly payment, we need to determine the number of $2,000 increments that the car costs. $30,000 ÷ $2,000 = 15.
So, the car costs 15 $2,000 increments.
Next, we need to multiply the number of increments by the $45 increase in payment per increment to find the monthly payment. 15 increments × $45/increment = $675.
Therefore, the monthly payment for a $30,000 car would be $675.

directly as the square root of C and
inversely as the cube of P. Given that C is
to decrease by 2% and P is to increase by
1%, determine the percentage change in S,
leaving your answer to the nearest whole
number.
Answers
Based on the proportionate equation of the selling price (S), cost price (C), and profit (P), the change in S caused by decrease of C and increase of P is decrease by 4%
Based on the given information, we know that:
S ∝ √C --> S directly varies as the square root of C
S ∝ 1/P³ --> S inversely as the cube of P
We can combine both relationships to make a proportionate equation:
S = √C / P³
We know from the case that:
ΔC = - 2%
ΔP = 1%
Then:
C' = C + ΔC
C' = C + (-0.02)P
C' = 0.98C
P' = P + ΔP
P' = P + (0.01)P
P' = 1.01P
S' = √C' / P'³
S' = √(0.98C) / (1.01P)³
S' = 0.96 √C/P³
S' = 0.96S
ΔS = S' - S
ΔS = 0.96S - S
ΔS = - 4%

The sum of the angles of the triangle below are angle A = 34.91°, angle B = 86.41°, and angle C = 58.68°.
What is triangle sum theorem?According to the triangle sum theorem, a triangle's internal angles can be added up to 180 degrees. The triangle sum theorem, often referred to as the angle sum theorem of the triangle, states that the total of the measures of a triangle's internal angles in a Euclidean space adds up to 180 degrees, whether the triangle is acute, obtuse, or right.
Let a = 8, b = 14 and c = 12 for the given triangle.
Then,
cos (A) = (b² + c² − a²) / 2bc
cos (A) = (14² + 12² - 8²)/ (2)(14)(12)
cos (A) = (196 + 144 - 64)/ 336
cos (A) = 0.82
A = cos⁻¹ (0.82)
A = 34.91°
Similarly, for angle B.
Cos (B) = (c² + a² − b²)/2ca
Cos (B) = (12² + 8² - 14²)/ (2)(12)(8)
A = cos⁻¹ (0.0625)
B = 86.41°
The sum of all the angles of a triangle is 180:
A + B + C = 180°
34.91° + 86.41° + C = 180°
C = 58.68°
Hence, the sum of the angles of the triangle below are angle A = 34.91°, angle B = 86.41°, and angle C = 58.68°.

The firm plans to acquire additional inventory to meet an unexpected surge in the demand for its products and will pay for the inventory with short-term debt. How much inventory can the firm purchase without violating its debt agreement if their total current assets equal $3.5 million?
Answers
The inventory can the firm purchase without violating its debt agreement is $777,777
What is liquidity ratio?Liquidity ratios are a class of financial metrics used to determine a debtor's ability to pay off current debt obligations without raising external capital.
Given that, Ronaldinho Trading Co. is required by its bank to maintain a current ratio of at least 1.75, and its current ratio now is 2.1.
Let X represent the additional borrowing against the firm’s line of credit (which also equals the addition to current assets).
We can solve for that level of X that forces the firm’s current ratio to be at 1.75
$3,500,000 / Current liabilities = 2.1
Current liabilities = $1,666,667
1.75 = ($3,500,000 + X) / ($1,666,667 + X) (1.75 * $1,666,667) + 1.75X
= $3,500,000 + X 0.75X = $3,500,000 – $2,916,667 X
= $777,777

What percent of 18 is 23? Round your answer to the nearest tenths.
Answers
The percent of 18 that equals 23 rounded to the nearest tenth is 127.8%.
What percent of 18 is 23?
Percentage is simply number or ratio expressed as a fraction of 100.
Given the data in the question;
Let x% represent the percentage of 18 that is equal to 23.
Note that x% is the same as x/100
Hence;
x/100 × 18 = 23
Solve for x
18x/100 = 23
Cross multiply
18x = 23 × 100
18x = 2300
Divide both sides by 18
18x/18 = 2300/18
x = 2300/18
x = 127.8

Slope intercept form of a line is y = mx + c, where m is the slope and c is the y intercept.
Given two lines on a graph.
Let y = m₁x + c₁ and y = m₂x + c₂ are the equations of two lines.
One line passes through (0, 1) and (1, 2).
m₁ = (2 - 1) / (1 - 0) = 1
Substituting m₁ = 1 and a point (x, y) = (0, 1) in y = m₁x + c₁,
1 = c₁
Equation of one line is y = x + 1.
Other line passes through (0, 0) and (1, -3).

A hose fills a hot tub at a rate of 3.76 gallons per minute. How many hours will it take to fill a 286-gallon hot tub?
Answers
Answer:
93.75min
Step-by-step explanation:
Solution:
The rate of fill up is, Rate = 3.2 Gallons / minute = 3.2 g/min
The hut tub volume is 300 Gallons
You can set up this problem as follows:
Every 3.2 gallons require 1 minute, How many minutes 300 gallons require?
3.2 g 1min
300 g ? min = (300 gallons x 1min/ 3.2 gallons)=(300/32)min
= 93.75 min
or simply the number minutes is the time required (T) the rate is (R) and the volume is (V)
such that T=V/R= (300g/3.2 g/min)= 93.75 min

An oil exploration firm is to drill 10 wells, each in different locations. Each well has a probability of 0.1 of producing oil. It will cost the firm $60,000 to drill each well. A successful well will bring in $1 million, taking into account the cost of drilling.
1. What is the probability that the firm will lose money on the ten wells?
2. What is the probability that the firm will gain $1.5 or more from the ten wells?
Answers
The probability the firm will lose money from 10 wells is 0.99 and the probability the firm will gain 1.5 million from the ten wells is 1 minus the CDF of 4 successful wells.
What is the probability the firm will lose or gain money1.
The expected profit from each well is $1 million - $60,000 = $940,000. The expected profit from all ten wells is $940,000 * 10 = $9,400,000. The probability of losing money on all ten wells is 1 - (0.1)^10 = 0.99
2.
To calculate the probability of gaining $1.5 million or more, we can use the cumulative distribution function (CDF) of the binomial distribution, which models the number of successful wells out of ten. The CDF gives the probability of getting a certain number of successful wells or fewer. To get the probability of getting more than a certain number of successful wells, we subtract the CDF of that number from 1. To get the probability of getting 2 or more successful wells, we subtract the CDF of 1 from 1, and so on. To get the probability of getting 5 or more successful wells, we subtract the CDF of 4 from 1, and so on. To get the probability of getting $1.5 million or more, we need to find the probability of getting 5 or more successful wells, since 5 wells at $1 million each give $5 million. The CDF of 4 successful wells can be found using statistical software or by using tables or approximations. The final answer is 1 minus the CDF of 4 successful wells.

Answers
A
The graph of the function g(x) = 1/x + 13 is a transformation of the graph of f(x) = 1/x. The transformation that has been applied is a vertical shift of 13 units upward. This means that every point on the graph of f(x) has been moved upward by 13 units along the y-axis, resulting in the new graph of g(x). In other words, the graph of g(x) will be parallel to the graph of f(x) but shifted upward by 13 units.
