Two taxi services charge different rates. Taxi A charges $0.40 per mile
traveled plus an initial charge of $2.00. Taxi B charges $0.50 per mile
traveled. The situation is modeled by this system, where xis the number of
miles traveled and y is the charge for that distance, in cents:
y= 40x+ 200
y= 50x
How many miles must each taxi travel for the charges to be equal, and what
is the charge for that distance?
Answers
Answer:
it would take 20 miles and cost 10 dollars.
Step-by-step explanation: Like up the equations so that 50x=40x+200. When you solve for x (number of miles) you find that x=20. Use 20 in either equation (0.5x or 0.4x+2) to get 10 (total cost).
did i get this question right?? please help me omg :((
Answers
Answer:
the answer is C because it's the only one that doesn't have any repeating x-values or repeating y-values.
D is incorrect because it's saying that no matter what the x-value is, the y-value will come out to be 6. that isn't a function
a function is when every x-value produces it's own y-value when plugged into the equation

if a car travels 120 miles in 4 hours. what is its speed per hour
Answers
Answer:
v = 30 km/h
Step-by-step explanation:
Given that,
Distance covered by a car, d = 120 miles
Time, t = 4 hours
We need to find the speed of the car. The speed of an object is equal to the distance covered divided by the time taken. It can be given by :
[tex]v=\dfrac{d}{t}\\\\v=\dfrac{120\ \text{miles}}{4\ \text{hour}}\\\\v=30\ \text{mph}[/tex]
So, the speed of the car is 30 km/h.

Answer:
∠A = 115°
∠B = 65°
∠C = 115°
∠D = 65°
Step-by-step explanation:
The figure given is of parallelogram.
We need to find measure of each interior angle.
We are given:
∠A = (2x-15)°
∠B = x°
∠C = (2x-15)°
∠D = x°
We need to find measure of ∠A , ∠B, ∠C, ∠D
We know that sum of all angles of parallelogram = 360°
So, we can write: ∠A +∠B+ ∠C+ ∠D = 360°
Now putting their values and finding value of x first:
[tex]2x-15+x+2x-15+x=360\\Combining\:like\:terms:\\2x+x+2x+x-15-15=360\\6x-30=360\\6x=360+30\\6x=390\\x=\frac{390}{6}\\x=65[/tex]
So, we get x= 65
Now finding measure of each angle:
∠A = (2x-15)° = 2(65)-15 = 130-15 = 115°
∠B = x° = 65°
∠C = (2x-15)° = 2(65)-15 = 130-15 = 115°
∠D = x°= 65°
Answer is:
∠A = 115°
∠B = 65°
∠C = 115°
∠D = 65°

Step-by-step explanation: For 10 builders to build a house in 20 days, the ratio is 1:2. For builders to build a house in 10 days, the ratio is x:10. You then cross multiply 1:2 and x:10. Then x=20 so 20 builders.
What is 3.116372 rounded to the nearest hundred thousandths place?
Answers
Explanation: The hundred thousandths place is in the fifth place after the decimal. To avoid remembering this, you can simply note that the first place after the decimal is the tenths. You simply keep progressing as you would in whole numbers.
For example 10 becomes 100 when a zero is added. This zero is always added right beside the first zero and indicates the hundreds place.
Furthermore, the general rule for rounding is if the number after the preferred rounding place is 4 or less, the number remains the same. 5 or more means it goes up by one digit.

I believe it is Y=30+2x
Step-by-step explanation:
Since the $30 is given no matter what, we can use it as b.
Since slope always changes, we use it as our m.
X= amount of people
2= charge per person
If there were 5 people there, the equation would look like this: y= $2(5)+$30
