The expression 4x gives the perimeter of a square with a side length of x units.What is the perimeter of a square with a side length of 5/7 units?
Answers
Answer:
The perimeter is units.
Step-by-step explanation:
The expression gives the perimeter of a square with a side length of x units.
So the function would be,
where,
f(x) is the function which gives the perimeter of the square, x as the side length.
As have to find the perimeter of a square with side length as , so we have to put x as
in the function.
Hence, the perimeter will be,
units

Answer:
let k represents the kumquat weight(in pound) and p represents the Asian pears weight respectively.
As per the given conditions,
The grocery store sells kumquat for $ 4.50 a pound
⇒ for 1 pound $4.50
then, in k pound =
similarly,
The Asian pears for $3.75 a pound
⇒ for 1 pound $3.75
then, in p pound =
Standard form of the equation is in the form of Ax + By = C:
The weight of kumquat k and Asian pears p that customer could buy with $ 16,
then the standard form of equation is: 4.50k +3.75p = 16
1 pound pear = 3.75
4.50k + 3.75p = 16

Write an equation to represent the possible numbers of cats and dogs that could have been at the
shelter on Wednesday.
Pat said that there might have been 8 cats and 14 dogs at the shelter on Wednesday. Are Pat’s
numbers possible? Use your equation to justify your answer.
Later, Pat found a record showing that there were a total of 22 cats and dogs at the shelter on
Wednesday. How many cats were at the shelter on Wednesday?
Answers
89.50=2.35c+5.50d
If theres 22 dogs and cats in total you can plug in number less than 22 for c(# of cats) and d(# of dogs).
So we try pats numbers 8 cats and 14 dogs so
89.50=2.35(8)+5.50(14)
89.50=18.8+77
89.50=95.8
So pats numbers were wrong so we try different numbers
So i started pluging in numbers from under 22 so i got c is 10 and d is 12 lets try it with the equation
89.50=2.35(10)+5.50(12)
89.50=23.5+66
89.50=89.50 so it works the answer to how many number of dogs and cats is 12 dogs and 10 cats
Final answer:
The equation representing the costs to care for the animals is 2.35c + 5.5d = $89.50. Pat's proposal of 8 cats and 14 dogs does not match the costs. Upon using additional information of the total number of animals being 22, we can solve the system of equations to find that there were 16 cats and 6 dogs at the shelter on Wednesday.
Explanation:
Let's denote the number of cats as c and the number of dogs as d. We know from the cost of care per day per animal that 2.35c + 5.5d = $89.50. This is the equation representing the possible number of cats and dogs at the shelter in terms of costs. For Pat's numbers, we can substitute c=8 and d=14 into the equation and check if they are possible. That is, substitute and check if 2.35(8) + 5.5(14) equals to 89.5. In this case, it does not since the total here comes to more than $89.50. So, Pat's numbers were not possible.
Regarding the total number of animals, we know that c + d = 22. With this equation, we can solve the system of equations to find out the actual number of cats and dogs at the shelter on Wednesday. Solving these two equations, we will find that 16 cats and 6 dogs were present at the shelter on Wednesday.

Part B: What is the value of the slope of the graph of velocity versus time between 10 minutes and 20 minutes, and what does the slope represent? (3 points)
Answers
slope = y2- y1 / x2-x1
= .8-.2 / 20-10 mi / min
= .6 / 10 min
= .06
Then for the follow up question, the slope represents the distance traveled of the toy car (in miles).
