Kayla works at flower store.the owner tells kayla he wants to take 10 percent off a 18.00$ bouquet. If the bouquet still doesn’t sell the owner will again reduce the sale price by 15 percent. Kayla tells the owner the original price by 25 percent because the sale price would be the same
Kayla is wrong because the calculation will give different amounts since one gave $13.77 while the other one was $13.50.
Taking 10% off and then 15% off will give a price that will be calculated thus:
= $18 - (10% × $18)
= $18 - $1.80
= $16.20
Taking 15% off will then be:
= $16.20 - (15% × $16.20)
= $16.20 - $2.43
= $13.77
Now taking 25% off directly firm $18.00 will give:
= $18.00 - (25% × $18.00)
= $18.00 - $4.50
= $13.50
Therefore, Kayla is wrong.

Donald Trump wants to build a 100 meter high tower as quickly as possible. He has unlimited resources and an unlimited budget and is willing to spend any amount to get the job done.
He has chosen to build the tower with blocks that are 100 meters long and 100 meters wide, but only 1 meter tall. The blocks interlock on top and bottom (like legos). They cannot be stacked sideways or on their ends.
Using special lifters, putting one stack on top of another stack takes one week regardless of how high the stacks are.
What is the shortest amount of time (weeks) that it will take to build the tower?
I looked up the answer, and everywhere it says that it is 10 weeks, but would it work with 1 stack of 100 blocks (1 week)?
Answer: 100 weeks
Step-by-step explanation: I think this is like a trick question or what not. I’m going to give you my best answer. It takes 1 week to stack a block and he wants it to be 100 meter tall. 1 block is one meter tall and since it takes 1 week per stack you would do 100 x 1 equals to 100 weeks. I know it says the shortest time but thats my best guess
It will take 100 weeks to build the tower.
Since Donald Trump wants to build a 100 meter high tower as quickly as possible with blocks that are 100 meters long and 100 meters wide, but only 1 meter tall, and using special lifters, putting one stack on top of another stack takes one week regardless of how high the stacks are, to determine what is the shortest amount of time (weeks) that it will take to build the tower, the following calculation must be performed:
Time per block x total blocks = Total time1 week x 100 = X100 weeks = XTherefore, it will take 100 weeks to build the tower.

scale the numerator and the denominator down by a factor of 3 (divide) to write a
fraction equivalent to 18/42
Answer:
6/14
Step-by-step explanation:
divide the numerator and denominator by 3. 18 / 3 is 6 and 42 / 3 is 14. So your answer is 6/14.
Answer:
6/14
Step-by-step explanation:
Scaling the numerator and denominator means to multiply or divide both numbers by some number. "Scaling down" means to divide both the numerator and denominator by some value (in this case, 3). So you would have to divide the numerator by 3 and the denominator by 3.
18 / 3 = 6
42 / 3 = 14
So you would get the equivalent fraction 6/14 when you scale down the numerator and denominator by 3.

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
-3.5 ÷ 7
This can be written as a fraction.
= -3.5/7
Remove the decimal point.
= -35/70
Divide both the numerator and denominator with 7.
= -5/10
Divide both the numerator and denominator with 5.
= -1/2

Find Y

Answer: 5[tex]\sqrt{3\\}[/tex]
Step-by-step explanation:
This triangle is a 30-60-90 triangle. This means that: x = 2a where a is the shorter leg of the triangle and x is the hypotenuse, and b = a[tex]\sqrt{3\\}[/tex] where b is the longer leg of the triangle.
Hypotenuse = 2 * the length of the shorter leg
Longer leg = [tex]\sqrt{3\\}[/tex] * the length of the shorter leg.
Since just visually speaking, y is the longer leg and 5 is the shorter leg, let's substitute y and 5 into the equation solving for the length of the longer side:
y = [tex]\sqrt{3\\}[/tex] * 5
y = 5[tex]\sqrt{3\\}[/tex]

A dilation is given by the transformation (x, y) →
(.75x, .75y). What type of dilation is this?
A) it is not a dilation
B) reduction
C) enlargement
Explanation:
We're multiplying each coordinate by 0.75, which is a value between 0 and 1. Whenever the scale factor is between 0 and 1, we always have a reduction. In this case, the linear dimensions are decreasing by 25% because 1-0.75 = 0.25 = 25%
So for instance, if the preimage had a side length of 12, then 0.75*12 = 9 is the corresponding image length. This is a reduction of 12-9 = 3. Then note how 3/12 = 0.25 = 25% is how much of a reduction we're dealing with.
DISTANCE FORMULA
find the distance between each pair of points round the answer to the nearest tenth
Step-by-step explanation:
The distance between 2 points is calculated with this formula:
[tex] \sqrt{(x2 - x1) {}^{2} + (y2 - y1) {}^{2} } [/tex]
• in the first exercise:
- the leftmost point has values (-5; 1), where -5 is the value of x1 and 1 is the value of y1
- the rightmost point has values (4; 0), where 4 is the value of x2 and 0 is the value of y2
then apply the formula:
[tex] \sqrt{(4 - ( - 5)) {}^{2} + (0 - 1) {}^{2} } [/tex]
[tex] \sqrt{(4 + 5) {}^{2} + (- 1) {}^{2} } [/tex]
[tex] \sqrt{81 + 1} [/tex]
[tex] \sqrt{82 } =9.05[/tex]
you can check if the result is correct by counting the distance of the points with the squares of the sheet (photo)
• in the second exercise:
- the highest point has values (-4; 2), where -4 is the value of x1 and 2 is the value of y1
- the lower point has values (-4; -4), where -4 is the value of x2 and -4 is the value of y2
then apply the formula:
[tex] \sqrt{( - 4 - ( - 4)) {}^{2} + ( - 4 - 2) {}^{2} } [/tex]
[tex] \sqrt{(0) {}^{2} + (36) } [/tex]
[tex] \sqrt{36} = 6[/tex]

Determine whether the lines AB and CD would be parallel, perpendicular, or neither?
A(-5,3) and B(-5, 7)
What is the slope of AB?
C(1, 9) and D(-10, 9)
What is the slope of CD?
What are the lines? (parallel, perpendicular or neither)
Answer:
Perpendicular
slope Ab = undefined
slope Cd = 0
Step-by-step explanation:
slope AB = undefined, a vertical line has no slope
slope CD = 0 (a horizontal line has no slope)
Answer:
AB: Undefined
CD: 0
Perpendicular
Step-by-step explanation:
Slope is the change in y over the change in x
(sometimes called "rise over run")
Formula looks like this:
[tex]\frac{y_{2} -y_{1}}{x_{2} - x_{1} }[/tex]
First let's find the slope of AB
[tex]\frac{7-3}{-5 --5 }[/tex]
[tex]\frac{7-3}{-5 +5 }[/tex]
[tex]\frac{4}{0}[/tex]
Undefined
Then the slope of CD:
[tex]\frac{y_{2} -y_{1}}{x_{2} - x_{1} }[/tex]
[tex]\frac{9 -9}{-10 - 1 }[/tex]
[tex]\frac{0}{-11 }[/tex]
0
If they are parallel they will have the same slope, perpendicular lines have negative reciprocals as the slope, and neither is neither
Comparing the slope of our lines lead us to know that the two lines are perpendicular because AB is vertically up + down and CD is horizontally right + left
I hope this is correct and helps, have a nice day :D
