A bike price is 159$ in january 2006 each year its price depreciates by 7 percent what will be its price at the end of 2007
AnsPlayrules eteanat b.
Step-by-step expfnkel
Answer:
$137.52
Step-by-step explanation:
To solve this we have the following equation
159*(.93)^n
where n is the number of years passed
Whenver we decrease the price by 7% we are essentially multiplying it by .93 which is why this equation works
To start on January 2006 and end at the end of 2007 means about 2 years has passed
This means we can plug in 2 for n
so we have
159*(.93)^2
Put this into your calculator and get 137.52
There are some beads in the box. 40% of them were blue and the rest were red. Adam used all the blue beads and 25% of the red beads to make a bracelet. what percentage of the beads was used to make the bracelet?
Answer:
65% of the beads were used to make the bracelet.
Step-by-step explanation:
40% of the beads were blue which means 60% of the beads were red. If all the blue beads were used that means 40% was used so you add the 25% of the red beads that were used which is why the answer is 65%.

Answer:
The equation of line in the form of Ax + By = C is: [tex]\mathbf{4x+y=-17}[/tex]
Step-by-step explanation:
We need to find the equation of line, having slope m = -4 and passes through point (-2,-9)
First we need to find slope and y-intercept of the line.
The slope is given i.e. m = -4
Now, we need to find the y-intercept
Using the point (-2,-9) and slope m = -4, y-intercept can be found using:
[tex]y=mx+b\\-9=-4(-2)+b\\-9=8+b\\b=-9-8\\b=-17[/tex]
Now, the equation of required line having slope m = -4 and y-intercept b = -17 is:
[tex]y=mx+b\\y=-4x-17[/tex]
Now writing in form of Ax + By = C
[tex]y=-4x-17\\4x+y=-17[/tex]
So, the equation of line in the form of Ax + By = C is: [tex]\mathbf{4x+y=-17}[/tex].
which numbers are irrational?
(ii) C is the point on the line y = 2x + 1 where x = 2.

??????????????????????????????????????
Answer:
C) N=3
Step-by-step explanation:
So an undefined problem can be represented as being divided by 0
So if the denominator is 0, it Would be undefined becuase after all every fraction is a division problem and you can‘t divide by 0
Test every possible option for n in the denominator becuase we don’t need to focus on the numerator due to only finding the denominator to be 0. The imperator doesn’t effect anything if the denominator is 0, it would only effect if the denominator is anything else which leads me to that the numerator COULD be 0 but not the denominator.
So in this case n=3 is a possibl solution becuase if solved using Orders of operations (Parethesis, exponents, etc.)
3(3-3)^2
3*0^2
0^2=0
0*3=0
So the denominator is 0 so c has to be the answer

140 divided in the ratio 4 : 3
Answer: 35:46
Step-by-step explanation:
When 140 is divided in the ratio 4:3, the two parts are 80 and 60, respectively.
To divide 140 in the ratio 4:3, we need to split the value 140 into two parts such that the ratio of the two parts is 4:3.
The ratio 4:3 consists of two parts (4 parts and 3 parts), making a total of 7 parts.
4+3=7
Divide 140 into 7 equal parts:
To find the value of one part, we divide 140 by 7:
140 ÷ 7
= 20
Calculate the two parts using the ratio:
Now, we can find the value of the two parts based on the ratio.
4 parts = 4 × 20 = 80
3 parts = 3 × 20 = 60
Hence, when 140 is divided in the ratio 4:3, the two parts are 80 and 60, respectively.

Billy is playing a game using a bag with 11 marbles inside. The bag contains 3 red, 3 orange, 1 yellow, 2 purple marbles, and 2 Pink. Each time he picks an orange marble, she will win a prize. If he picks a marble twice, WITHOUT replacement, what is the probability he will win a prize on both picks? 5/110 5/21 3/55 9/121
Answer: 3/55
Step-by-step explanation:
From the information given, the bag contains 3 red, 3 orange, 1 yellow, 2 purple marbles, and 2 Pink marbles. Each time he picks an orange marble, she will win a prize.
If he picks a marble the first time, the probability of picking an orange marble will be 3/11. After that we will have 10 marbles left as one has been picked and have 2 orange marbles left, then the probability of picking another orange marble will be 2/10.
Therefore, the probability he will win a prize on both picks will be:
= 3/11 × 2/10
= 6/110
= 3/55
At the beginning of the season, carl had to remove 50 dead orange trees from his farm while each of the remaining trees produced more than 210 oranges. Write mathematical sentences describe the number of oranges produced
Answer:
y > (x - 50) * 210
Step-by-step explanation:
Given :
Number of dead trees = 50
Number of oranges produced by each of the remaining trees > 210
Let total number of trees = x ; total number of oranges produced = y
Hence, number of oranges produced, y
y > number of remaining trees * number of oranges produced per tree
y > (x - 50) * 210

Lexi is making a scale drawing of a soccer field that is 120 yards long and 80 yards wide and the field is that see strong is 30 cm wide how long should the field be in drawing
Answer:
45 cm
Step-by-step explanation:
l = Length of football field is 120 yards
w = Width of football field is 80 yards
The ratio of the sides is [tex]\dfrac{l}{w}=\dfrac{120}{80}=\dfrac{3}{2}[/tex]
Now the width of the field is 30 cm = w'
[tex]\dfrac{l'}{w'}=\dfrac{l}{w}\\\Rightarrow l'=\dfrac{l}{w}\times w'\\\Rightarrow l'=\dfrac{3}{2}\times 30\\\Rightarrow l'=45\ \text{cm}[/tex]
The length of the field in the drawing is 45 cm.
What is m∠D?
m∠D = °
The measure of Angle D is the same as Angle B which is 63 degrees.
How does an angle form?An angle requires two straight line/ line segments/rays, such that they're connected on one of their endpoints. The point of their joint is called the vertex of that angle. Those two line segments forming it are called arms of that angle. One arm is fixed, and one arm rotates around that vertex to make angles of different measurements. The fixed arm is called the initial arm. The moving arm is called the terminal arm.
The angle is the degree of rotation that it will take for the moving side to go from the initial side to the position it is currently on.
We are given that m∠B = 63°
Since the lines BC and AD are parallel to each other, they form the quadrilateral ABCD and parallelogram.
Therefore, according to the parallelogram properties,
the measure of Angle D is the same as Angle B which is 63 degrees.

Answer:
[tex]y=+\frac{2\sqrt{2} }{3}\\[/tex]
Step-by-step explanation:
In the unit circle we have:[tex]x^{2} +y^{2} =1[/tex]In the picture we see that x=1/3.
Using de equation of unit circle:[tex](\frac{1}{3} )^{2} +y^{2} =1\\\\\frac{1+9y^{2} }{9}=\frac{9}{9} \\\\y^{2} =\frac{8}{9} \\\\\sqrt{y^{2}} =\sqrt{\frac{8}{9}}\\\\y=+\frac{2\sqrt{2} }{3}[/tex]
y is positive because y are in the first quadrant of the cartesian plane.

Can anybody explain how to turn percentages to fractions or fractions to percentages, and diving and dividing decimals and studying tips thank you.
Converting fractions, decimals, and percents
When we talk, we often use different words to express the same thing. For example, we could describe the same car as tiny or little or small. All of these words mean the car is not big. Fractions, decimals, and percents are like the words tiny, little, and small. They're all just different ways of expressing parts of a whole.
screenshot of 1/2
In this image, each measuring cup has the same amount of juice in it. But we've expressed this amount in three ways: as a fraction, as a percent, and as a decimal. Since they're expressing the same amount, we know that 1/2, 50%, and 0.5 are equal to each other. Any time we see 1/2, we'll know it can also mean 50% or 0.5.
Sometimes it's useful to convert one kind of number into another. For example, it's much easier to add 1/4 and 0.5 if you turn 0.5 into a fraction. Learning how to convert fractions, decimals, and percents will also help you as you learn more advanced math.
Fractions and decimals
Every fraction can also be written as a decimal, and vice versa. You may not do this very often, but converting decimals and fractions can help you in math. For example, it's easier to subtract 1/6 from 0.52 if you turn 1/6 into a decimal first.
Converting a fraction into a decimal
Let's convert a fraction into a decimal. We'll be using a math skill you've already learned: long division. To refresh your memory on this skill, you can review our Long Division lesson.
