Given a unit circle, what is the
value for y?
(1/3, y)
y = ?
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.

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

If two angles form a linear pair and the measure of one of the angles is 73º, what is the
measure of the other angle?
Answer:
107
Step-by-step explanation:
180 -73 is 107 hope that helps
Answer: 107°
Step-by-step explanation:
Linear pairs are supplementary so they have to add up to 180°.
x = meas. of other angle
x + 73 = 180
Subtract both sides by 73
x = 107
The measure of the other angle is 107°.
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.

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.

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.

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
n=3

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
