A total of 395 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was three times the number of adult tickets sold. How many adult tickets were sold?

Answer:

A. and D.

Step-by-step explanation:

Hey there!

In order to to find the point at which these two equations intersect at, you need to first rewrite the equations if needed so that they are in the form:

[tex]y=mx+b[/tex]

or

[tex]y=ax^2+bx+c[/tex]

The first equations needs to be rewritten

[tex]3x+5=y+4x[/tex]

make [tex]y[/tex] by itself

[tex]3x+5-4x=y[/tex]

Simplify LHS

[tex]y=-x+5[/tex]

Now we have it in slope-intercept form

Looking at the equation, we can tell that the slope of the line is [tex]-1[/tex] and the y-intercept is 5

Now you can graph this equation easily (image down below)

The second equation is already in form so there is no need to rewrite anything

We can go straight to graphing (image down below)

Now plot both equations on the same graph (image down below)

Answer:

2√3

Step-by-step explanation:

root 27

= √27

= 3√3

12 upon root 3

= 12 / √3

= ( 12 / √3 ) x ( √3 / √3 )

= ( 12 x √3 ) / ( √3 x √3 )

= 12√3 / 3

= 4√3

6 upon √3

= 6 / √3

=  ( 6 / √3 ) x ( √3 / √3 )

= ( 6 x √3 ) / ( √3 x √3 )

= 6√3 / 3

= 2√3

root 3 = √3

root 3 + root 27 - 12 upon root 3 + 6 upon root 3

= √3 + 3√3 - 4√3 + 2√3

= 4√3 - 4√3 + 2√3

= 2√3

Simplifying

I think its the third one

Answer:

y = cos(2x)

Step-by-step explanation:

This is equation must be a cosine function because it starts at a nonzero number. We can conclude that the final answer is D because the amplitude is 1 not 2. Also, the period (2π/k) is equal to 2π/π = 2.

See the image below for the different parts of a cosine/sine function.

These are the three basic trigonometric ratios:

Here, 'opposite' or adjacent are referring to the legs in relation to one of the interior angles of the triangle, θ.

We can use these ratios to help us solve for side lengths or angles, depending on what information is given to us and what information we must solve for.

We're given:

Because this question involves the adjacent and the opposite, we can use the tangent ratio to find the answer.

[tex]\tan(\theta)=\dfrac{opposite}{adjacent}[/tex]

⇒ Plug in the given information:

[tex]\tan(70^\circ)=\dfrac{opposite}{5.7}[/tex]

⇒ Multiply both sides by 5.7 to isolate 'opposite:

[tex]5.7\tan(70^\circ)=opposite\\opposite = 15.66062\dots[/tex]

⇒ Round to the nearest tenth:

[tex]opposite=15.7[/tex]

The length of the other leg is 15.7 units.

Answer:

D  4+p=24

Step-by-step explanation:

So P stands for Paul & how much he spent.

Dan spent $24 at the store & he spent $4 more than Paul, so Paul only spent $20.  So P = $20

So which equation would work if you substituted $20 for P?

4 + P = 24

4 + 20 = 24

Answer:

1,055.04

Step-By-Step explanation:

Volume equals pi times radius squared times the hight.

You first calculate what the radius will be by dividing the diameter by two and then you procede to multiply the radius to a power of two which is the equvialent as multiplying it to the base number and then you multiply the then squared radius to pi and lastly multiply it by the hight and you have your answer.

[tex]\pi * (8x^{2}) * 21 \\\pi * (4x^{2}) * 21\\\pi * 16 * 21\\50.24 *21\\=1,055.04[/tex]

The measure of the length of the dotted line is 3.75 inches. Then the correct option is B.

The hexagon is a two-dimensional geometry with six sides. And the polygon's sides are all straight lines that are joined side by side.

The perimeter of the hexagon is 7.5 inches.

Then the length of the hexagon will be

[tex]\rm 7.5 = 6x\\\\x \ \ = 1.25[/tex]

The length of the hexagon is 1.25 inches.

Then the diagonal length of the hexagon will be

y = 2 × 1.25

y = 2.5

The diagonal length of the hexagon is 2.5 inches.

Then the length of the dotted line is 3.75 inches.

Probability of a blue chip

Probability of two blue chips is

Answer:

[tex]\sf \dfrac{9}{169}[/tex]

Step-by-step explanation:

The bag has:

⇒ Total number of chips = 6 + 13 + 7 = 26

Probability Formula

[tex]\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}[/tex]

Probability of choosing a blue chip from the first draw:

[tex]\implies \sf P(Blue)=\dfrac{6}{26}[/tex]

As the chips are replaced, the probability of choosing a blue chip from the second draw is the same as the first.

Therefore, the probability of taking out a blue chip in both draws is:

[tex]\begin{aligned}\implies \sf P(Blue)\:and\:P(Blue) & = \sf \dfrac{6}{26} \times \dfrac{6}{26}\\\\& = \sf \dfrac{6 \times 6}{\26 \times 26}\\\\& = \sf \dfrac{36}{676}\\\\& = \sf \dfrac{36 \div 4}{676 \div 4}\\\\& = \sf \dfrac{9}{169}\end{aligned}[/tex]

plug the 5 into the function

f(5)=(5)^2-5

f(5)= 25-5

f(5)=20

Step-by-step explanation:

Answer:

Step-by-step explanation:

so, we're going to plug in 5 as our x value, and the equation becomes:

f(5) = [tex](5)^{2}[/tex] - (5)

now we'll simplify

f(5) = 25 - 5

The total amount of money that Stephen would pay his uncle is equal to $10,600.

Mathematically, simple interest is calculated by using this formula:

I = PRT

Where:

Given the following data:

Interest rate = 2% = 0.02.

Principal = $10,000.

Time = 3 years.

Substituting the given parameters into the formula, we have;

I = 10000 × 0.02 × 3

I = $600.

Amount of balance;

A = I + P

A = 600 + 10,000

A = $10,600.

Step-by-step explanation:

I took the quiz on EDGE 2022

Using the binomial distribution, it is found that there is a 0.0368 = 3.68% probability that the teacher first draws Milani's name as the 7th student.

The formula is:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

In this problem, there are 20 students, hence in each question the probability that Milani's name is called is p = 1/20 = 0.05.

The probability that the teacher first draws Milani's name as the 7th student is P(X = 0) when n = 6(none during the first six) multiplied by 0.05(called during the seventh), hence:

P(X = 7) = (0.95)^6 x 0.05 = 0.0368.

0.0368 = 3.68% probability that the teacher first draws Milani's name as the 7th student.
