A car has an initial velocity of 10 m/s and final velocity of 43 m/s. The time taken
to reach the final velocity was 3 seconds. What is the acceleration of the car?
Hint: Acceleration (in terms of velocity) = (final velocity - initial velocity)/(time) *
Answers
Answer:
160 m/s
Step-by-step explanation:
vi= 10m/s
a= 5om/s*2
t=3 second
vf=?
frist step: find s(distance)
s=vit+1/2 at*2=10m/s x3s +0.5 x50m/s*2 (3s)*2 =30m+225m=255m
second : find vf
s=(vf+vi)/2 xt
vf=2s/t- vi=2(255m)/3s -10 m/s=170 m/s-10m/s=160m/s
Therefore , the final velocity of the car is 160m/s

P= -2
All real numbers
P = 2
P= 5
Answers
Answer:
P = All real numbers
Step-by-step explanation:
Step 1: Write equation
4p + 5 + p = 2p + 5 + 3p
Step 2: Solve for p
Combine like terms: 5p + 5 = 5p + 5Subtract 5 on both sides: 5p = 5pDivide both sides by 5: p = pHere we see that any value p would render the equation true. Therefore, we have an infinite amount of solutions.

Walter is making curry for dinner. The recipe says that the curry should cook for 1 hour and 25 minutes. He has been cooking the curry for 59 minutes. According to the recipe, how much longer does Walter need to cook the curry? Write the answer in minutes. minutes
Answers
Answer:
26 minutes.
Step-by-step explanation:
1 hour = 60 minutes. 60 minutes + 25 miuntes= 85 minutes of total cook time. 85 - 59 = 26. We do this because he has already cooked for 59 minutes, and the total time is 85 minutes.
Explain whether the points (−3,8), (−2,3), (−1,−2), (0,−7), (1,−12), and (2,−17) represent the set of all the solutions for the equation y=−5x−7.
A.Yes, because all solutions in the set of solutions for y=−5x−7 need to have integer values for both x and y.
B.Yes, because all of the points that are listed are on the line y=−5x−7.
C.No, because the x-intercept is not provided in the list of points.
D.No, because the set of all solutions of y=−5x−7 is represented by the line of the equation
Answers
Answer:
D
Step-by-step explanation:
We simply put each of the points to test
For a point to be correct, if we substitute the x-coordinate value, we should get the value of the y-coordinate
So let’s proceed
(-3,8)
8 = -5(-3) - 7
8 = 15 -7
8 = 8
(-2,3)
3 = -5(-2) - 7
3 = 10 -7
3 = 3
(-1,-2)
-2 = -5(-1) - 7
-2 = 5-7
-2 = -2
(0,-7)
y = -5x -7
y = -5(0) - 7
y = 0-7 = -7
(1,-12)
y = -5(1) -7
-12 = -5 -7
-12 = -12
(2,-17)
-17 = -5(2) -7
-17 = -10-7
-17 = -17
We can see that all the listed points are on the given line
Although all these points lie on the line, we cannot say they represent the set of all solutions
The set of all solutions can simply be represented by the line of the equation

When a positive sign is considered then the value of x is -4 and when a negative sign is considered then the value of x is -14.
What is simplification?Simplification is to make something easier to do or understand and to make something less complicated.
The equatiuon is (x + 9)² = 25.
Take square root on both sides, then we have
(x + 9) = ±5
For positive signs, we have
x + 9 = 5
x = -4
For negative signs, we have
x + 9 = -5
x = -14

What is inequality?Inequality is simply a type of equation that does not have an equal sign in it. Inequality is defined as a statement about the relative size as well as is used to compare two statements.
The inequality is given as
9.53 < √a < 9.54
On squaring both sides, we have
9.54² > a > 9.53²

Answers
Answer:
a. -1.60377
b. 0.25451
c. 0.344
d. Option b) 78th
Step-by-step explanation:
The number of pieces in a regular bag of Skittles is approximately normally distributed with a mean of 38.4 and a standard deviation of 2.12.
a)What is the z-score value of a randomly selected bag of Skittles that has 35 Skittles? a) 1.62 b) -1.62 c) 3.40 d) -3.40 e)1.303.
The formula for calculating a z-score is is z = (x-μ)/σ,
where x is the raw score
μ is the population mean
σ is the population standard deviation.
z = 35 - 38.4/2.12
= -1.60377
Option b) -1.62 is correct
b) What is the probability that a randomly selected bag of Skittles has at least 37 Skittles? a) .152 b) .247 c) .253 d).747e).7534. .
z = (x-μ)/σ
Mean of 38.4 and a standard deviation of 2.12.
z = (37 - 38.4)/2.12
= -0.66038
P-value from Z-Table:
P(x<37) = 0.25451
The probability that a randomly selected bag of Skittles has at least 37 Skittles is 0.25451
Option c) .253 is.correct
c) What is the probability that a randomly selected bag of Skittles has between 39 and 42 Skittles? a) .112 b) .232 c) .344 d).457 e).6125.
z = (x-μ)/σ
Mean of 38.4 and a standard deviation of 2.12.
For 39 Skittles
z = (39 - 38.4)/2.12
= 0.28302
Probability value from Z-Table:
P(x = 39) = 0.61142
For 42 Skittles
z = (42 - 38.4)/2.12
= 1.69811
Probability value from Z-Table:
P(x = 42) = 0.95526
The probability that a randomly selected bag of Skittles has between 39 and 42 Skittles is:
P(x = 42) - P(x = 39
0.95526 - 0.61142
0.34384
= 0.344
Option c is.correct
d) What is the percentile rank of a randomly selected bag of Skittles that has 40 Skittles in it? a)82nd b) 78th c) 75th d)25th e)22nd
z = (x-μ)/σ
Mean of 38.4 and a standard deviation of 2.12.
z = (40 - 38.4)/2.12
= 0.75472
P-value from Z-Table:
P(x = 40) = 0.77479
Converting to percentage = 0.77479× 100
= 77. 479%
≈ 77.5
Percentile rank = 78th

Ahmad runs 7 miles in 80 minutes. At the same rate, how many miles would he run in 64 minutes?
Answers
5.6 Miles
Explanation:
7/80=0.0875 Miles per minute
0.0875*64= 5.6 Miles
So,
A) 80 min will be divided by 7 miles-
80/7 = 11.43 min/ mile
Ahmad runs 1 mile in approximately 11.43min.
B) How long will he run in 64 min?-
Since we know that it takes 11.43min to run 1 mile, we will divide 64 by that 1 mile time.
64/11.43 = 5.6 miles in 64 min.
Our answer is: Ahmad will run 5.6 miles in 64 min.
Another way to solve this, is by cross multiplying:
A)7/80 • x/64 = 448/80x. Now, solve for x by...
B) 448/80 = 5.6
