Answer:

The total  number of votes was [tex]7,007[/tex]

Step-by-step explanation:

Let

x -----> the number of yes votes

y -----> the number of no votes

we know that

[tex]\frac{x}{y} =\frac{6}{5}[/tex]

isolate variable y

[tex]y=\frac{5}{6}x[/tex] -----> equation A

[tex]x=3,822[/tex] -----> equation B

Substitute equation B in equation A and solve for y

[tex]y=\frac{5}{6}(3,822)=3,185[/tex]

therefore

To find out the total number of votes sum the number of yes votes plus the number of no votes

[tex]3,822+3,185=7,007[/tex]

(4x – 12) + (–x + 7)

Open the parenthesis

=4x-12-x+7

Solve the like terms:

=3x-5

The answer is 3x-5

Answer:

Step-by-step explanation:

The correct answer would be -18

To solve this, you would substitute x with the x value, which in this case is -2

That would make it so f(x)= 9(-2)

9*-2=-18

Therefore f(x)=-18

Note that f(x) is another way to write y, therefore...

y = 9x

To solve for this plug -2 in for x in this equation like so...

y = 9 * -2

When a positive number is being multiplied with a negative number the answer will be negative.

y = -18

C. is the answer (assuming that you meant to write -18 instead of 1 18)

Answer:

lol i need help with the same question

Step-by-step explanation:

Roger, with a batting average of 0.250, recorded 60 successful hits from a total of 240 attempts. Therefore, he failed to get a hit 180 times.

In this question, we are dealing with Roger's batting average and his performance. A batting average of 0.250 means that for every 4 at-bats, Roger gets a hit on average 1 time. So, if he has been at bat a total of 240 times, we can expect that he got hits 0.250 times out of these at-bats. So to calculate the number of successful hits, we multiple 240 by 0.250 which equals 60. Therefore, Roger has hit the ball 60 times. To find out how many times he failed to get hits, we subtract his hits from his total tries. So, 240 - 60 = 180. Therefore, Roger failed to get a hit 180 times.

Let me know if this was right :)                                                

Answer:

[tex]\sin(x)=\frac{\sqrt{95}}{12}=0.8122[/tex]

[tex]\cos(x)=\frac{7}{12} \approx .5833[/tex]  

[tex]\tan(x)=\frac{\sqrt{95}}{7} \approx 1.3924[/tex]  

[tex]x=\sin^{-1}(\frac{\sqrt{95}}{12}) \approx 54.3147[/tex] degrees.

I don't know what you want to round to but I can tell you are rounding...

Step-by-step explanation:

Soh Cah Toa is the acronym we will use to help us solve this.

This says sine is opposite over hypotenuse.

It also says cosine is adjacent over hypotenuse.

And finally tangent is opposite over adjacent.

Note:  Opposite and adjacent can change depending on how you are looking at the triangle, like which angle you are referring to.

Let's look at x:

The side that is opposite, not touching, the angle whose measurement is x, is the side that has measurement [tex]\sqrt{95} \approx 9.7[/tex].

I see you already found this measurement. This is really good.  I might use the exact value for now and round at the end.

The side that is the hypotenuse no matter the angle you are referencing is always going to be opposite the angle whose measurement is 90 degrees. It is also the longest side (since it is opposite the largest angle).  This side has measurement 12.

The hypotenuse will be one of the sides touching your angle you are referencing.  The other side that is touching your angle is the adjacent side.  This side has measurement 7.

Anyways let's plug into the definitions we had above:

[tex]\sin(x)=\frac{\sqrt{95}}{12}[/tex]  (O/H)

[tex]\cos(x)=\frac{7}{12}[/tex]   (A/H)

[tex]\tan(x)=\frac{\sqrt{95}}{7}[/tex]   (O/A)

Now we can solve anyone of these for x.

Take your pick.

[tex]\sin(x)=\frac{\sqrt{95}}{12}[/tex]

[tex]x=\sin^{-1}(\frac{\sqrt{95}}{12})[/tex]

[tex]x=54.3147[/tex] degrees.  

Answer:

option B

Step-by-step explanation:

Given:

per day late costs= 1.50

Purchase price= 9.99

A round trip cab ride to the video store will cost = 10

5 day late cost= 5(1.50)

                       = 7.50

Payment after 5 day late= 5 day late cost + Purchase price

                                       = 7.50 + 9.99

                                       = 17.49

If she gets a cab, then total payment= 10 + 7.50

                                                             = 17.50

Hence both costs almost the same, option B is true

Answer: A) 1.7 Years

Step-by-step explanation:

Answer:

A. 1.7 years

Step-by-step explanation:

Let [tex]P_1[/tex] be the original value of first car,

Since, the car depreciates at an annual rate of  10%,

Let after [tex]t_1[/tex] years the value of car is depreciated to 60%,

That is,

[tex]P_1(1-\frac{10}{100})^{t_1}=60\%\text{ of }P_1[/tex]

[tex]P_1(1-0.1)^{t_1}=0.6P_1[/tex]

[tex]0.9^{t_1}=0.6[/tex]

Taking ln on both sides,

[tex]t_1ln(0.9) = ln(0.6)[/tex]

[tex]\implies t_1=\frac{ln(0.6)}{ln(0.9)}[/tex]

Now, let [tex]P_2[/tex] is the original value of second car,

Since, the car depreciates at an annual rate of 15%

Suppose after [tex]t_2[/tex] years it is depreciated to 60%,

[tex]P_2(1-\frac{15}{100})^{t_2}=60\%\text{ of }P_2[/tex]

[tex]P_2(1-0.15)^{t_2}=0.6P_2[/tex]

[tex]0.85^{t_2}=0.6[/tex]

Taking ln on both sides,

[tex]t_2ln(0.85) = ln(0.6)[/tex]

[tex]\implies t_2=\frac{ln(0.6)}{ln(0.85)}[/tex]

[tex]\because t_1-t_2=\frac{ln(0.6)}{ln(0.90)}-\frac{ln(0.6)}{ln(0.85)}[/tex]

[tex]=1.70518303046[/tex]

[tex]\approx 1.7[/tex]

Hence, the approximate difference in the ages of the two cars is 1.7 years,

Option 'A' is correct.

20% of 50 is found by multiplying the base (50) by the decimal equivalent of the percent (0.2). The calculation yields an amount of 10, which indicates that 20% of 50 is 10.

Calculating percents involves using the basic equation that relates the percent, the base (also called 'whole' or 'total'), and the amount (or 'part'). The equation can be represented as percent = (amount/base)  imes 100. To find what is 20% of 50, we use this equation, where the percent is known (20%) and the base is known (50), but the amount is what we are looking for.

First, let's convert the percent to a decimal to make the calculation easier: 20% = 20/100 = 0.2. Then, we multiply the base (50) by the decimal form of the percent (0.2): 50 x 0.2 = 10. So, 20% of 50 is 10.

Therefore, the correct representation relating the Percent, Amount, and Base in this problem is option A) Percent=20%, Amount=50, Base=unknown, since we're calculating the amount based on the known percent and base.

Answer:

C.) percent= 20%, Amount=unknown, Base =50

Step-by-step explanation:

20% is the percent

50 is the amount

20% of 50 is the unknown. This is the amount.

20% of 50 = 0.2 × 50 = 10

Answer:

Mary = 24

Chau = 15

David = 48

Step-by-step explanation:

The formula is

Mary + Chau + David = 87

And we know that

Chau = Mary - 9

David = Mary * 2

So when we fill this in

Mary + Mary - 9 + Mary * 2 = 87

4Mary - 9 = 87

4Mary = 96

Mary = 24

Chau = Mary - 9 = 15

David = Mary * 2 = 48

Final answer:

The problem is solved using basic algebra, yielding Chau has $15, Mary has $24, and David has $48, all adding up to the total amount of $87.

Explanation:

The question involves a three-person word problem focusing on algebraic relationships and equation solving. Mary, Chau, and David have a total of $87 in their wallets. Mary has $9 more than Chau, and David has twice what Mary has. To find out how much each person has, we'll let 'c' represent the amount that Chau has.

Accordingly, Mary has c + $9, and David has 2(c + $9). Together, they have a total of c + (c + $9) + 2(c + $9) = $87. Simplifying this, we get 4c + $27 = $87. Subtracting $27 from both sides gives us 4c = $60. Dividing both sides by 4, we find that Chau has $15.

Now, since Mary has $9 more than Chau, Mary has $24 ($15 + $9). David, having twice what Mary has, possesses $48 (2 x $24). These amounts add up to the total of $87.

Answer:

See below.

Step-by-step explanation:

Compare our equation with one  standard form of a circle:

x^2 + y^2 = r^2    where r = the radius.

So x^2 + y^2 = 9 is the equation of a circle with it's center at the origin and it's radius is 3 units.

x^2 + y^2 = 0 is not a circle because r = 0  ( a radius of 0). A circle of radius 0 is really a point!!

The value of the radius of a circle  must be positive  so it cannot have a radius of -3.

Answer

[tex]x ^{2} + {y}^{2} = r^{2} [/tex]

since all the terms are squared so there can be a negative number

but in number line

...... -4,-3,-2,-1,0,1,2,3.......

as we know negative sign indicates only the direction so -3 means in which coordinates will it lie.

Answer:

A=$538.82

Step-by-step explanation:

We're going to use the compounded interest formula:

A=P(1+r/n)^n*t

Where,

A = the future value of the investment/loan, including interest

P = the principal investment amount (the initial deposit or loan amount)

r = the annual interest rate (decimal)

n = the number of times that interest is compounded per unit t

t = t is the amount of time at which you're checking how much it's worth (yrs)

Using this information, we can use:

A=500(1+0.025/4)^3*4

A=500(1+0.00625)^12

A=500(1.00625)^12

A=500(1.07763259886)

A=538.82

A=$538.82....

Answer: P(red): 1/2

P(red or black):3/4

Step-by-step explanation: Count the total number of marbles. There are 8. Since there are 4 red marbles out of the 8, put this into a fraction. It will be 4/8, but simplify to 1/2. The P(red) is 1/2.

Since there are 4 red marbles and 2 black marbles, add them. There are 6 out of the 8 marbles. The fraction is 6/8 simplify to 3/4. The P(red or black) is 3/4.

The probability of choosing a red marble from the box is 0.5 and the probability for choosing either a red or black marble is 0.75.

The subject of this question refers to calculating probabilities which is a concept in Mathematics, specifically in the scope of Statistics. To calculate the probability of an event, we need to know the total amount of outcomes and the amount of favorable outcomes. In the context of the question, these outcomes are represented by marbles.

First, we need to add the total number of marbles, which is 4 red + 2 black + 2 green = 8 marbles in total.

To find the probability of picking a red marble, we divide the number of red marbles by the total number of marbles. Hence, P(red) = 4/8 or 0.5.

To find the probability of picking a red or black marble, we add the number of red and black marbles and divide by the total number of marbles. Hence, P (red or black) = (4 red + 2 black) / 8 total = 6/8 or 0.75.

[tex]xy=\log_{5\sqrt{5}}\left(5\sqrt{5}\right)^2\cdot\log_{2\sqrt{2}}\left(2\sqrt{2}\right)^4[/tex]

Using the properties of logarithm, we get

[tex]xy=2\cdot 4[/tex]                    [tex][\because log_aa^x=x][/tex]

[tex]xy=8[/tex]

Therefore the product of x and y is 8.

Answer:

Increasing

Step-by-step explanation:

Let's see what happens if we choose a value for b greater than 1.

Let's try b=2.

[tex]f(x)=2^x[/tex].

I'm going to keep increasing x. If y increases, the the function is increasing. If y decreases, the function is decreasing.

Let's start with x=1.

[tex]y=2^1=2[/tex]

Now x=2.

[tex]y=2^2=4[/tex]

The y's got higher as you increased x so the function is increasing.

The function keep increasing for the varying value of x, hence the exponential function is increasing

Given the exponential function f(x) = [tex]b^x[/tex]

We are to check if the function is increasing or decreasing if b is greater than 1

Let b = 2 and x = 1

[tex]f(1) = 2^1\\f(1) = 2[/tex]

Let b = 2 when x = 2

[tex]f(2)=2^2\\f(2)=4[/tex]

Let b = 2 when x = 3

[tex]f(3)=2^3\\f(3)=8[/tex]

You can see that the function keep increasing for the varying value of x, hence the exponential function is increasing
