Find the time.
I = prt
Principal: $500
Rate: 5%
Interest earned: $25
Time: ?
Answer:
1 year
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
t = 25 / ( 500 × 0.05 ) = 1
t = 1 years
The time required to
accumulate simple interest of $ 25.00
from a principal of $ 500.00
at an interest rate of 5% per year
is 1 year.

How does Reflection work in real-life situations?
Answer:
reflection is defined as the change in the direction of a wavefront at the interface between two different media, bouncing the wavefront back into the original medium. A common example of reflection is reflected light from a mirror or a still pool of water, but reflection affects other types of waves beside light.

8
7
% compounded quarterly. After 15 years, how much more money would Lily have in her account than Lincoln, to the nearest dollar?
Answer: 445
Step-by-step explanation:
Lincoln’s Final Amount:
Compounded Continuously: A=Pe^rt
P= 2800
r= 0.05375
t=15
A=2800e^0.05375(15)
A=2800e^0.80625
A=6270.5833
Lily’s final amount:
Compounded quarterly:
A=P(1+r/n)^nt
P=2800
r=0.05875
t=15
n=4
A=2800(1+ 0.05875/4)^4(15)
A=2800(1.0146875)^60
A=6715.7829
How much more money does Lily have?
6715.7829-6270.5835
=445.1994
The money would Lily have in her account than Lincoln, to the nearest dollar 445.
We have to determine the compound interest Lincoln’s final amount
Compounded Continuously
A=Pe^rt
P= 2800
r=0.05375
t=15
A=2800e^0.05375(15)
A=2800e^0.80625A=6270.5833
What is the formula for compound interest?
A=P(1+r/n)^nt
P=2800
r=0.05875
t=15
n=4
A=2800(1+ 0.05875/4)^4(15)
A=2800(1.0146875)^60
A=6715.7829
=6715.7829-6270.5835
=445.1994
Therefore money would Lily have in her account than Lincoln, to the nearest dollar 445.

If a set of parallel lines contains the two points, (-2, 3) and (8, -5). If the lines are rotated 180 degrees clockwise, what would the two coordinates be after the rotation? Show or explain your work.
The two coordinates after the rotation are (2,-3) and (-8,5)
How to determine the coordinates after rotation?The points are given as:
(-2,3) and (8,-5)
The rule of 180 degrees clockwise rotation is:
(x,y) = (-x,-y)
This means that:
(2,-3) => (-2,3)
(-8,5) => (8,-5)
Hence, the two coordinates after the rotation are (2,-3) and (-8,5)

Answer:
(2, -3) and (-8, 5)
Step-by-step explanation:
If a point is rotated 180° clockwise about the origin (0, 0) then:
(x, y) → (-x, -y)
Therefore,
(-2, 3) → (-(-2),-3) = (2, -3)
(8, -5) → (-8, -(-5)) = (-8, 5)
So the two coordinates after rotation would be (2, -3) and (-8, 5).

Answer:
A
Step-by-step explanation:
3/5 is the same as 6/10. All percentages are out of 100% so you have to change the denominater to 100. Do do that you just add a 0 to the numerator and demoninator. i.e. 60/100. which is translated to 60%.
Which equation can be rewritten as x + 4 = x2?
Assume x>0.
O √x+2=x
O √x+2 = X
O √x+4 = X
O √x2 + 16 = X
Which equation can be rewritten as x + 4 = x2?
Right ans is √x+4 = x
❣️
The equation x + 4 = x² will be written as √( x+2 ) = x. The correct option is B.
What is an expression?In mathematics, expression is defined as the relationship of numbers, variables, and functions using mathematical signs such as addition, subtraction, multiplication, and division.
The given expression is x + 4 = x². The given expression will be simplified as below,
x + 4 = x²
Remove the square and apply the square root on the left side of the equation.
x = √ ( x + 4 )
Therefore, the equation x + 4 = x² will be written as √( x+2 ) = x. The correct option is B.

A good trick for fractions is to take the top number and divide it by the bottom number. This gives you the number version of the fraction. For example in question 4. 5/4 is 1.25. And 10/8 is 1.25. therefore they have the same value. Also another good trick. If the top number is more than the bottom number we know it will be 1 something because their is more than the bottom number. So if we have for example question 3 we know that 4 thirds will be at least 1 something if we divide it. And if we look at 8 ninths we know it will be less than 1 something since I is less than nine. Therefore if divided they will have different numbers

The area of a circle can be found using the formula [tex]A=\pi r^2[/tex]
Step-by-step explanation:
A high school physics teacher was conducting an experiment with his class on the length of time it will take a marble to roll down a sloped chute. The class ran repeated trials in order to determine the relationship between the length, in centimeters, of the chute and the time, in seconds, for the marble to roll down the chute. A linear relationship was observed and the correlation coefficient was 0.964. After discussing their results, the teacher instructed the students to convert all of the length measurements to meters but leave the time in seconds. What effect will this have on the correlation of the two variables
Answer:
Step-by-step explanation:
Because changing from centimeters to meters does not affect the value of the correlation, the correlation will remain 0.964.
The effect does have on the correlation of the two variables should be that it remain the same i.e. 0.964.
Impact on the correlation of the two variables:Since there is the changing from centimeters to meters so this does not impact the correlation value due to which it remain the constant i.e. 0.964.
Also, the correlation coefficient should be unit -less and the value should always ranged between -1 to 1.
Therefore, it remains the constant.

Which is parallel to the following y=2x+1
a. Y=2x +5
B. Y- =4 (x+1)
C, Y=(-⅓)x +4
D. Y= 3x +7
Answer:
a. y = 2x + 5
Step-by-step explanation:
f two lines are parallel to each other, they have the same slope.
The first line is y = 2x + 1. Its slope is 2.
A line parallel to this one will also have a slope of 2.
a. y = 2x + 5
This line also has a slope of 2. It is a possible choice.b. y = 4(x + 1)
This line has a slope of 4. It will not be parallel.c. y = (-1/3)x + 4
This line has a slope of -1/3. It will not be parallel.d. y = 3x + 7
This line has a slope of 3. It will not be parallel.Therefore, your answer is a. y = 2x + 5.
