Answer: 1/12
Step-by-step explanation:
Number of sugar cookies = 6
Number of lemon cookies = 4
Number of chocolate cookies = 2
Total number of cookies = 6+4+2 = 12
The probability of firs choosing a sugar cookie will be: = 6/12 = 1/2
The probability of then choosing a chocolate cookie will be: = 2/12 = 1/6
Then we multiply both probabilities together and this will be:
= 1/2 × 1/6
= 1/12

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).
Difference of two whole numbers is 33 and its ratio is 2:5 then find those
numbers.
Answer:
Step-by-step explanation:
Let the two whole numbers be 5x and 2x then
by the question
5x - 2x = 33
3x = 33
x = 33/3
x = 11
Therefore the numbers are
5x = 5*11 = 552x = 2*11 = 22hope it helps:)

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.

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.

Step-by-step explanation:
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

can u help me find the area
Answer:
640 units squared
Step-by-step explanation:
The shape below is a trapezoid.
The formula for the area of a trapezoid is average of the bases times the height.
The bases are the parallel lines that make up 2 of the sides of the trapezoid.
The height is the line dotted line that creates right angles and is the distance between the two bases.
The bases are 24 and 40.
To find the average, we add them together and divide by 2
(24+40)/2=64/2=32
Now, we multiply 32 by the height, which is given as the length of 20.
32*20=640
the area of the trapezoid is 640 units squared

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.

% 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.
