1/2 x 62 x 0.5² = 7.75
A woman is walking at a rate of 0.5m/s. Her mass is 62 kg. The woman's kinetic energy in joules:
K.E. = 7.75 kgm²/s²
What is Kinetic Energy?
The energy an object has as a result of motion is known as kinetic energy in physics. It is described as the effort required to move a mass-determined body from rest to the indicated velocity. The body holds onto the kinetic energy it acquired during its acceleration until its speed changes.
Given,
Mass = 62kg
Velocity = 0.5m/s
The formula for Kinetic Energy is :
K.E. = 1/2 m v².
K.E. = 1/2 (62)(0.5)²
K.E. = 1/2 (62)(0.25)
K.E. = 1/2 (15.5)
K.E. = 15.5/2
K.E. = 7.75 kgm²/s²
or
K.E. = 7.75 joules
Hence, he woman's kinetic energy in joules, K.E. = 7.75 kgm²/s²

4 - 2 = 2 hoursThe number of children at the library was 3 times the number adults. The total number of people at the library was 48. How many children were at the library
A 12
B 24
C 32
D 36
Answer:
D 36
Step-by-step explanation:
Write the information algebraically
c = 3a
c + a = 48
c = children, a = adults
In the second sentence (in bold), we can replace c with 3a
c + a = 48 → 3a + a = 48
Simplify
3a + a = 48 → 4a = 48 → a = 12 (divide both sides by 4)
We can then substitute or plug in a = 12 into the original equation:
c + a = 48 → c + 12 = 48 → c = 36 (subtract 12 from both sides)
There are 36 childrenCan Pi be written as a fraction?
Answer:
no
Step-by-step explanation:
1. Pi is an irrational number, and irrational numbers CANNOT be written as a fraction. Pi is a non-repeating, non-terminating decimal number.
2. While 22/7 and 3.14 is often used as a value for pi, these are just approximations, so they're not completely exact.
You deposit $200 in a savings
account that pays a simple
interest rate of 3.25% per year.
How much interest will you earn
after 5 years?
Answer:
$32.50
Step-by-step explanation:
The equation for simple interest is
Simple Interest=P×r×n
where:
P=Principal amount
r=Annual interest rate
n=Term of loan, in years
so
P=200
r=0.0325
n=5
so 200*0.0325*5=32.5

Answer:
k=2
Step-by-step explanation:
2x-8y+k/2=0
puting the values of x and y
2*2-8*1+k/2=0
4-8+k/2=0
-4+k/2=0
k/2=4
sing changes if side changed
k=4/2
k=2
We first substituted the X and Y in the equation, so 2 instead of X and 1 instead of Y.
Then I moved the K to make it the subject of the equation by algebra which gave me a -K, but I want k not negative k so I multiplied everything by -1 because, -1 × -1= +1 so K=2.

Figure ABCD is transformed to figure A prime B prime C prime D prime, as shown: A coordinate grid is shown from negative 5 to 0 to 5 on both x -and y-axes. A polygon ABCD has A at ordered pair 1, 3, B at ordered pair 3, 4, C at ordered pair 2, 1, D at ordered pair 1, 1. A polygon A prime B prime C prime D prime has A prime at ordered pair negative 3, 3, B prime at ordered pair negative 5, 4, C prime at ordered pair negative 4, 1, D prime at ordered pair negative 3, 1. Which of the following sequences of transformations is used to obtain figure A prime B prime C prime D prime from figure ABCD? (1 point) Reflection about the x-axis followed by a translation to the right by 2 units Reflection about the y-axis followed by a translation to the left by 2 units Counterclockwise rotation by 90 degrees about the origin followed by a translation to the right by 2 units Counterclockwise rotation by 90 degrees about the origin followed by a translation to the left by 2 units
Answer:
i need this answer too
Answer:
The appropriate choice is the 2nd one ...
... Reflection over the y-axis followed by a translation down by 5 units.
Step-by-step explanation:
The transformed figure has the opposite orientation (A'B'C'D' is counterclockwise, whereas ABCD is clockwise), so a reflection is involved. The sgment C'D' is still at the bottom, as is CD, so the reflection must be across a vertical line.
In the attached, the light-blue figure A''B''C''D'' shows the reflection of ABCD across the y-axis. It is easy to see that figure A'B'C'D' is a translation of that 5 units downward.
The appropriate choice is the 2nd one ...
... Reflection over the y-axis followed by a translation down by 5 units.

Answer:
7.4
Step-by-step explanation i took the test
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
x - x/2 - 6.8 = -3.1
x = 7.4
The temperature at the beginning of the day was 7.4°F.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
The temperature at the beginning of the day = x
The temperature during the day = x/2
The temperature after the sun goes down = 6.8°F
The temperature at the end of the day = -3.1°F
Now,
We can write an expression as,
x - x/2 - 6.8 = -3.1
x - x/2 = -3.1 + 6.8
x/2 = 3.7
x = 7.4°F
Thus,
The temperature at the beginning of the day was 7.4°F.
