(1) The first velocity of the car with two washers at the 0.25 meter mark is 0.125 m/s.
(2) The second velocity of the car with two washers at the 0.5 meter mark is 0.25 m/s.
What is velocity?Velocity is the rate of change of displacement with time. The velocity of the cars depends on displacement and time of motion.
First velocity of the car at the 0.25 meter markThe first velocity is calculated as follows;
v1 = 0.25 m / t1
let t₁ = 2 s
v₁ = 0.25/2
v₁ = 0.125 m/s
Second velocity of the car at the 0.5 meter markv2 = 0.25 m / (t2 – t1)
let t₂ = 3 s
v₂ = 0.25(3 - 2)
v₂ = 0.25 m/s
The complete question is below:
Calculate the first and second velocities of the car with two washers attached to the pulley, using the formulas
v1 = 0.25 m / t1, and
v2 = 0.25 m / (t2 – t1)

Daniel can spend no more than $40 at the fair. If admission into the fair is $10 and the rides cost $1.50 each, which inequality represents the greatest number of rides Daniel can go on?
A. 10r + 1.50 ≥ 40 B. 1.50r + 10 ≤ 40 C. 1.50r + 10 <40 D 10r+1.50<40
Explain your reasoning and solve the inequality :
Answer:The answer is B.
Step-by-step explanation: He has to spend 10 dollars to get into the fair and each ride cost 1.50. We don’t know how many rides he’s going to get on so that is an unknown variable multiplied by 1.50 (r). He also has to spend less than or equal to $40. So Daniel’s total of 1.50r + 10 has to be less than or equal to $40.

b minus 21 = 177
Subtract 21 from the left side and add 21 to the right side of the equation.
The answer is b = 198.
Check the solution by substituting 198 for b.
Add 21 to the left side and subtract 21 from the right side of the equation.
The answer is b = 156.
Check the solution by substituting 198 for b.
Subtract 21 from both sides of the equation.
The answer is b = 156.
Check the solution by substituting 156 for b.
Add 21 to both sides of the equation.
The answer is b = 198.
Check the solution by substituting 198 for b.
Answer:
D. Add 21 to both sides of the equation.
The answer is b = 198.
Check the solution by substituting 198 for b.
Step-by-step explanation:
D. 21-21= 177+21=198

198-21=177
The steps are needed to solve b - 21 = 177 equation are:
Add 21 to both sides of the equation.
The answer is b = 198.
Check the solution by substituting 198 for b.
What is an equation?"It is a statement which consists of equal symbol between two mathematical expressions."
What is the solution of the equation?"It is the set of all values that that make an equation true."
For given question,
We need to solve the equation b - 21 = 177
⇒ b - 21 = 177 ................(original equation)
⇒ b - 21 + 21 = 177 + 21 .................(Add 21 to each side)
⇒ b = 198
Therefore, the steps are needed to solve b - 21 = 177 equation are:
Add 21 to both sides of the equation.
The answer is b = 198.

Lucy has 68 books.
This number of books is 70% more than the number of books she had last year.
How many books did Lucy have last year?
Answer:
Lucy had 40 books last year.
Step-by-step explanation:
assuming 100% is the percent;
100% + 70%
100 : x
170 : 68
cross multiply = 170x = 100 x 68
-------- ————-
170 170
cancel 170/170
therefore x = 100 x 68 divided by 170
result is 40
The number of books that Lucy has last year will be 40 books.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
Lucy has 68 books. This number of books is 70% more than the number of books she had last year.
Let 'n' be the number of books. Then the equation is given as,
1.7 n = 68
n = 68 / 1.70
n = 40
The number of books that Lucy has last year will be 40 books.

I believe the answer is C. 1,131 miles
Step-by-step explanation:
When we use a right triangle to solve, we already know the angles on the right triangle must be 45 45 90, since all triangles equal 180. Then using tan45 times 800 we get the side between Houston and Lincoln which is also 800. Pythag then solves 800²+800²=c²
c²=1280000 so √1280000 =1131
The answer is C.)
The side of Lincoln to Tallahassee is the largest. The distance between Houston and Tallahassee is smaller, meaning that it is accurately a larger number. It would be simple to understand that the base and height of the triangle could NOT add up to 1,600 because they would both have to be at least HALF the length of the distance between Tallahassee but they are not. Meaning the answer is 1,321
