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]

Answer:

D. 15/17

Step-by-step explanation:

Sine is opposite/hypotenuse and the opposite side to 62 degrees is 15 while the hypotenuse is 17

The value of sin 62° will be equal to 15/17.

Trigonometry is the branch of mathematics which set up a relationship between the sides and angle of the right-angle triangles.

The formula for sin angle is given as:-

SinФ = Perpendicular /  Hypotenuse

From the figure, Perpendicular is 15 and the hypotenuse is 17 so the value will be:-

Sin62°  =  15  /  17

Therefore the value of sin 62° will be equal to 15/17.

Answer:

10.4

Step-by-step explanation:

The way to find percentage is by multiplying the number you want to find the percentage of by the percentage and divide it by 100

So, in the case of 16% of 65

we multiply 65 by 16 =1040

then we divide by 100

Hence 1040/100=10.40

which is same as 10.4

HOPE IT HELPS....

The solution of the expression 16 percent of 65 is 10.4.

A percentage is a ratio that may be written as a fraction of 100.

A fraction is a ratio between two quantities. The upper part is called numerator and the lower part is called denominator.

A collection of constants, variables connected using one or more arithmetic operator is called an expression.

This can be simplified as:

[tex]\dfrac{16}{100} \times65 = 10.4[/tex]  in decimal form.

Thus, 16 percent of 65 is 10.4

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]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]

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.

Step-by-step explanation:

Factorial is used to multiply any natural number with all the numbers smaller than it. It is denoted by n! (n is the natural number)

where n! = n*(n-1)*(n-2)*(n-3)*(n-4) so on....

For example if we take factorial of 5.

Then,

5!= 5*(5-1)*(5-2)*(5-3)*(5-4)

= 5*4*3*2*1

= 120

It is used for the questions which asks us to order a number of things or in how many ways you can arrange something....

Factorial is a key function in mathematics used to calculate permutations and arrangements. It represents the number of ways objects can be arranged within a set number. Factorial is essential in combinatorics and probability theory.

Factorial is a mathematical function denoted as n! and calculated as the product of all positive integers up to n.

The purpose of factorial is to represent the number of ways in which a set of objects can be arranged or permutations can be made within a set number of objects.

Factorial is extensively used in mathematics, especially in combinatorics and probability theory.

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

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
