For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.
Which one is right and why?
Answers
THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!
The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.
The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

First thing we need to do is find the inside angle at point L. Simply take the outside angle of 134 and subtract it from 180. 180-134 = 46. We then do the same for point M. 180-84 = 96. Finally, we add these together then subtract the sum from 360. 46+96 = 142. 360 - 142 = 218. The value of x is 218. Hope this helps!

A cage has canaries and parakeets in the ratio 4:7. another cage has cockatiels and parakeets in the ratio 5:8. are the ratios of birds in the two cages equivalent?
Answers
Answer: No
Step-by-step explanation:
think of 4:7 as a fraction. that would be 4/7 right? so compare that to 5:8 as a fraction- 5/8. Are these fractions the same? the answer is no.
Answer: No.
Step-by-step explanation: In this situation, you should be able to multiply the lesser ratio by a certain number and it should be equivalent with the bigger one.
Example:
1:1
2:2
For this example, you would want to multiply 1:1 by Q. Q will be our variable here. So, 1 times q equals 2. Q would be equivalent to 2, now multiply both the 1's in 1:1.
The two ratios also don't hold the same types of birds, so it cannot be equivalent whatsoever.

solve each compound inequality
f-4<5 and f-4 ≥ 2
y-1 ≥7 or y+3<-1
-5<3p+7≤22
Answers
To solve each compound inequality, we can break it into two separate inequalities and solve each one separately.
For the first compound inequality, f-4<5 and f-4 ≥ 2, we can break it into two separate inequalities: f-4<5 and f-4>2. Solving these inequalities separately, we get:
f-4<5
f<9
f-4>2
f>6
Therefore, the solution to the compound inequality is 6<f<9.
For the second compound inequality, y-1 ≥7 or y+3<-1, we can break it into two separate inequalities: y-1>=7 and y+3<-1. Solving these inequalities separately, we get:
y-1>=7
y>=8
y+3<-1
y<-4
Therefore, the solution to the compound inequality is y<-4 or y>=8.
For the third compound inequality, -5<3p+7≤22, we can break it into two separate inequalities: -5<3p+7 and 3p+7≤22. Solving these inequalities separately, we get:
-5<3p+7
3p>-12
p>-4
3p+7≤22
3p≤15
p≤5
Therefore, the solution to the compound inequality is -4<p≤5.

What is the distance between 8 and −4
Answers
Answer:
12 units
Step-by-step explanation:
The distance is always positive!
So, if you look on a number line, and count the distance between 8 and -4, it would be 12. Something to remeber is, you can't subtract the values from each other, rather add them. Sooo, you can't do 8-4, but you can do 8+4, or 8-(-4) (since two negative signs equal a positive). This applies to every senario where there is a negitive factor, and the problem is asking for the distance.
Distance and absolute value are always positive

Bruce collects coins. He collected a total of 250 coins. If 76% of the coins he collected were foreign, how many other coins did he collect?
Answers
Step-by-step explanation:
Total number of coins he collected = 250 coinsPercentage of coins he collected which were foreign = 76 %So,
→ Number of coins he collected which were foreign = 76% of 250
→ Number of coins he collected which were foreign = \( \dfrac{76}{100} \) × 250
→ Number of coins he collected which were foreign = \( \dfrac{76}{10} \) × 25
→ Number of coins he collected which were foreign = \( \dfrac{1900}{10} \)
→ Number of coins he collected which were foreign = 190
Now,
→ Other coins he collected = Total coins - Number of coins he collected which were foreign
→ Other coins he collected = 250 - 190
→ Other coins he collected = 60
Therefore, he collected 60 other coins.

A department store offered a 15% discount off the regular price of a shirt. The amount of the discount is $3. What is the regular price of the shirt?
Answers
Answer: $3.53
Step-by-step explanation: 15 percent off can be thought of as 85% of the original value because 100-15 is 85. this means that if x is the value of the original shirt, .85x=3
divide by .85
x=3.5294
which is about $3.53
Answer:
You will pay $12 for a item with original price of $15 when discounted 20%. In this example, if you buy an item at $15 with 20% discount, you will pay 15 - 3 = 12 dollars.

Type fractions like this: numerator/denominator
type the numerator, a slash, and the denominator WITH NO SPACES between each part
Answers
Answer:
1 1/5.
Step-by-step explanation:
To divide a fraction by another fraction you have to change the equation like "Keep, Switch, Flip".
For the problem 24/25 ÷ 4/5,
You KEEP the first fraction as is, so 24/25
Then, you SWITCH the sign from division to multiplication.
Finally, you FLIP the second fraction upside down, (the reciprocal). So it's 5/4.
The equation is now 24/25 * 5/4, which we can just multiply the numerators and denominators. (or cross cancel first)
24 * 5 = 120
25 * 4 = 100
the fraction is 120/100. Simplified, it can be divided by 10 to make 12/10, and finally divided by 2 to make 6/5, or 1 1/5.
