A car is moving at a steady rate. The distance it travels is proportional to the amount of time, in hours, it has been driving. It has traveled a total of 168 miles in 3 hours. (a) What is the ratio of the distance to the number of hours? Express as a fraction and as a unit rate with appropriate units.
Answers
Step-by-step explanation:
let distance travelled be d miles and time be t hours.
d = kt where k is a constant, k ≠ 0
168 = 3k
k = 56
d/t = k
hence it's ratio is 56 : 1 and fraction is 168/3 = 56/1 and fraction with unit is 56miles/hour.

What are the excluded values of x for
Answers
Answer:
x = - 2, x = 9
Step-by-step explanation:
Given
f(x) = [tex]\frac{x^2-9x}{x^2-7x-18}[/tex]
The denominator of f(x) cannot be zero as this would make f(x) undefined.
Equating the denominator to zero and solving gives the values that x cannot be.
x² - 7x - 18 = 0
(x - 9)(x + 2) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 9 = 0 ⇒ x = 9
The excluded values are x = - 2, x = 9

i posted the same question but they didn’t tell me how they got it so could someone show me how they got the answer pleaseee
Answers
Answer:
y= -6
Step-by-step explanation:
-4y - 20 + 19 = -y + 17 *add y on the right to get rid of -y
+y +y then add it to -4y
-3y - 20 + 19 = 17 *add 20 to the left to get rid of -20
+20 +20 then add it to 17
-3y + 19 = 37 *subtract 19 from the left to get rid of 19
-19 -19 then subtrcat 19 from 37 as well
-3y = 18 *now we want to divide both sides by -3 to
-3 -3 get y by it's self
y = -6 *no we're left with y = -6 :D

Each correct answer is worth 134 points, and each incorrect answer is worth −14 points. If he gets 58 questions correct and 22 questions incorrect, does Nevan win? How many points does he score?
Answers
Answer:
i. Yes, Nevan won.
ii. Nevan scored 7464 points.
Step-by-step explanation:
Given: each correct answer = 134 points
each incorrect answer = -14 points
Since he got 58 questions correctly, then;
His number of points = 134 x 58
= 7772 points
Also, he got 22 incorrect questions, then;
His number of points = -14 x 22
= -308
Nevan's total points = 7772 + (-308)
= 7772 - 308
= 7464
Nevan scored 7464 points.
Nevan won, and also had a total of 7464 points.
Answer:
yes nevan won

The plans for a new street show lamp post that are 2.5 inches apart. If the plans use a scale of 0.5 inch = 9 yards, find the actual distance between the lamp posts.
Answers
Answer: 45 yards
Step-by-step explanation:
From the question, we are given the information that the plans for a new street show lamp post that are 2.5 inches apart and that the plans use a scale of 0.5 inch = 9 yards,
Since a scale of 0.5 inch = 9 yards is used, the actual distance between the lamp posts will be:
= (2.5inches / 0.5 inches) × 9 yards
= 5 × 9 yards
= 45 yards

2 2 /5 = 2.4 = 240 %
Step-by-step explanation:
The number 1 is the same as 1.00 and is the same as 100%.
The number 2, therefore, is the same as 2.00 and the same as 200%
2 /5 can be converted into a decimal by seeing that 2 /5 = 4 /10 . 4 /10 , spoken out loud, is "four tenths" and shows that the decimal is
0.4 . And 0.4 is the same as 40%. Which means that 2 2 /5 = 2.4= 240 %
