We know that the total number of chairs must be the product between the number of chairs per row and the total number of rows, which can be expressed as

[tex]c \times r = 55[/tex]

Where [tex]c[/tex] represents the number of chairs per row and [tex]r[/tex] representes the number of rows.

The second given statment defined a second equation

[tex]r=2c+1[/tex]

Now, we can substitute the second equation into the first one, and solve

[tex]c \times r = 55\\c (2c+1)=55\\2c^{2}+c-55=0[/tex]

Which can be factored by multiplying the expression by 2, and solve has a perfect trinomial

[tex]2(2c^{2}+c-55)=0\\2^{2}c^{2}+2c- 110=0\\(2c)^{2}+2c-110=0[/tex]

So, we need to find two number which product is 110 and is 1. If you think this through, those numbers are 11 and 10, because 11*10=110 and 11-10=1.

The factors are

[tex]\frac{(2c+11)(2c-10)}{2} =0[/tex], we have to divide by the number we multiplied before, then we simplify this number with the second factor

[tex](2c+11)(c-5)=0[/tex]

Where the positive solution is the only one that can be part of the answer because it doesn't make sense if we say -3 chairs. So,

[tex]c-5=0\\c=5[/tex]

This means there are 5 chairs per row.

Then, we use this value to find the other one.

[tex]c \times r=55\\5 \times r=55\\r=\frac{55}{5}\\ r=11[/tex]

Therefore, there are 11 rows and 5 chairs per row.

Answer:

[tex]p = -10x + 200[/tex]

[tex]m = -10x^2 +200x[/tex]

Step-by-step explanation:

We know that at a price of $ 150, 5 televisions are sold and at a price of $ 100, 10 televisions are sold.

We must write a linear equation for this situation.

The equation of the line will have the following form

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

Where m is the slope of the line and b is the intercept with the p axis

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{100-150}{10-5}=-10[/tex]

[tex]b=p_1-mx_1\\\\b=150-(-10)(5)\\\\b=200[/tex]

The equation is:

[tex]p = -10x + 200[/tex]

Now we know that the revenue m is the product of the price p for the quantity sold x.

[tex]m = p * x[/tex]

[tex]m=(-10x + 200)*x[/tex]

[tex]m = -10x^2 +200x[/tex]

Answer:

[tex]p=-10x+200[/tex]

[tex]m = -10x^2+200x[/tex]

Step-by-step explanation:

Given : An electronics store discovers that it can sell 5 televisions per day by pricing them at $150. When the televisions are on sale for $100 the store sells 10 of them every day.

To Find: Write a linear equation to compare the price of a television, p, to the number sold, x. Then write a quadratic equation to compare the revenue, m, from selling televisions to the number sold, x.

Solution:

Let p be the price and x be the no. of television sold

We are given that  it can sell 5 televisions per day by pricing them at $150. When the televisions are on sale for $100 the store sells 10 of them every day. i.e(5,150) and (10,100)

Now to find the linear equation to compare the price of a television, p, to the number sold, x.

We will use two point slope form

Formula : [tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex](x_1,y_1)=(5,150)[/tex]

[tex](x_2,y_2)=(10,100)[/tex]

Substitute the values in the formula

[tex]y-150=\frac{100-150}{10-5}(x-5)[/tex]

[tex]y-150=\frac{-50}{5}(x-5)[/tex]

[tex]y-150=-10(x-5)[/tex]

[tex]y-150=-10x+50[/tex]

[tex]y=-10x+50+150[/tex]

[tex]y=-10x+200[/tex]

x is the no. of television sold

y is the price

Since p denotes the price

So,  [tex]p=-10x+200[/tex]

Thus a linear equation to compare the price of a television, p, to the number sold, x is   [tex]p=-10x+200[/tex]

Now [tex]Revenue = Cost \times quantity[/tex]

Since price of x telivisons = [tex]p=-10x+200[/tex]

So,  [tex]Revenue = (-10x+200) \times x[/tex]

[tex]Revenue = -10x^2+200x[/tex]

m denotes revenue

So,[tex]m = -10x^2+200x[/tex]

Thus a quadratic equation to compare the revenue, m, from selling televisions to the number sold, x. is [tex]m = -10x^2+200x[/tex]

Hence a linear equation to compare the price of a television, p, to the number sold, x is   [tex]p=-10x+200[/tex] and a quadratic equation to compare the revenue, m, from selling televisions to the number sold, x. is [tex]m = -10x^2+200x[/tex]

Answer:

6 units

Step-by-step explanation:

Calculate the distance d using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 7, 1) and (x₂, y₂ ) = (- 7, - 5)

d = [tex]\sqrt{(-7+7)^2+(-5-1)^2}[/tex]

  = [tex]\sqrt{0+(-6)^2}[/tex] = [tex]\sqrt{36}[/tex] = 6 units

Final answer:

The distance between the points (-7, 1) and (-7, -5) on the coordinate plane is 6 units, calculated by the absolute difference in their y-coordinates.

Explanation:

The distance between the points (-7, 1) and (-7, -5) on the coordinate plane can be found by calculating the difference in their y-coordinates. Since the x-coordinates are the same, the points lie on a vertical line, and the distance is simply the absolute difference in the y-coordinates.

The calculation would be: distance = |y2 - y1| = |-5 - 1| = | -6 | = 6 units

Therefore, the distance between the two points is 6 units.

Step-by-step explanation:

1/2(130-80)

Answer:

(B)

Step-by-step explanation:

Given: It is given that arc AD=130° and arc AB=arc CD=80°.

To find: The measure of ∠APD.

Solution: It is given that arc AD=130°⇒m∠AOD=130° (The measure of the central angel is equal to the intercepted arc)

Also, arc AB=arc CD=80°⇒m∠AOB=m∠DOC=80° (The measure of the central angel is equal to the intercepted arc)

We know that the sum  of the central angles is equal to 360°, thus

m∠AOD+m∠AOB+m∠BOC+m∠COD=360°

⇒130°+80°+m∠BOC+80°=360°

⇒290°+m∠BOC=360°

⇒m∠BOC=360°-290°

⇒m∠BOC=70°

Now, since  (The measure of the central angel is equal to the intercepted arc), therefore arcBC=70°.

Also, we know that Angle Formed by Two Secants is half of the DIFFERENCE of Intercepted Arcs, therefore

[tex]m{\angle}APD=\frac{1}{2} (arcAD-arBC)[/tex]

Substituting the values, we get

[tex]m{\angle}APD=\frac{1}{2} (130-70)[/tex]

⇒[tex]m{\angle}APD=\frac{60}{2}[/tex]

⇒[tex]m{\angle}APD=30^{\circ}[/tex]

Thus, the measure of ∠APD is 30°.

Hence, option B is correct.

One centimenter is 0.01 meters. So, you can write the measures as

[tex] 152.40\text{m},\quad 205.10\text{m},\quad 310.39\text{m}[/tex]

Once this rewriting is done, getting the total length [tex]T[/tex] is quite trivial, since all measurements are in the same unit, and we can simply sum everything:

[tex]T = 152.40+205.10+310.39 = 667.89[/tex]

The problem is a basic mathematical exercise involving negative and positive numbers related to bank transactions. The original balance is overdrawn and represented as a negative number, and then deposits and withdrawals are added and subtracted respectively to find the new balance which still ends up overdrawn.

The problem given is about mathematical operations and bank transactions. The subject here is a subtraction and addition problem involving negative and positive numbers. The initial account balance represented as '––$324' shows an overdrawn account and is a negative number. Then, the account holder deposited checks, which is a positive value represented by '3(150)', and each deposit is $150 making it a total deposit of $450. Then, the account holder made withdrawals represented by '4(–20)', each withdrawal of $20 thereby making a total withdrawal of $80. Therefore, to find the new balance of the account, the calculation should be as follows: '–324 + 3(150) – 4(20) -> –324 + 450 – 80', which equals 46, indicating that the account is overdrawn by $46.

Answer:

[tex]A.\ y-6=-\dfrac{5}{6}(x+5)\\\\B.\ y-1=-\dfrac{5}{6}(x-1)[/tex]

Step-by-step explanation:

The point-slope form of an equation of a line:

[tex]y-y_1=m(x-x_1)[/tex]

m - slope

(x₁, y₁) - point

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have the points (-5, 6) and (1, 1). Substitute:

[tex]m=\dfrac{1-6}{1-(-5)}=\dfrac{-5}{6}\\\\\text{For point (-5, 6):}\\\\y-6=-\dfrac{5}{6}(x-(-5))\\\\y-6=-\dfrac{5}{6}(x+5)[/tex]

[tex]\text{For point (1, 1):}\\\\y-1=-\dfrac{5}{6}(x-1)[/tex]

If 1 inch equals 20miles then 8 inches equals 20 x 8 = 160 miles.

So you want to find out the distance for both the cities. Since there are 8 inches to both cities, then the answer would be 160 miles since every inch would equal to 20 miles, which is the actual distance.

Answer: a compound event is when only 2 things can happemn

you divide the first number by the second number

you would creat a spinner with several collers then each coler would be a event you spin and that coler is the event

7/37

please give me brainly

Step-by-step explanation:

An example of a compound event is tossing a coin and drawing a card; it involves multiple independent events. A spinner for probability should represent outcomes fairly. The probability that Max picks 2 cat's eye marbles consecutively is calculated by multiplying the probability of each selection.

Understanding Compound Events and Probability

An example of a compound event is tossing a coin and drawing a card from a poker deck simultaneously. It is classified as a compound event because it consists of two independent events that result in a combined outcome. The probability of a compound event is calculated using the product rule when the events are independent. This is done by multiplying the probabilities of each independent event occurring on its own.

To create a spinner that simulates the probability of an event, identify all the possible outcomes and ensure they are represented on the spinner fairly, with areas proportional to the probabilities of the outcomes. Spin the spinner a large number of times, documenting the outcomes to estimate the probability based on relative frequency.

Calculating the probability that Max picks 2 cat’s eye marbles in a row involves dependent events since the outcome of the first draw influences the outcome of the second. Initially, there is a 7/37 chance of picking a cat’s eye marble. Once one is picked, there are 6 cat’s eye marbles left and 36 marbles in total, so the probability of the second pick being a cat’s eye marble is 6/36. The combined probability is (7/37)*(6/36).

1. 12 bags for total cost of 119.88

2. Yes. You'll make $180.12 for your labor.

3. Other tools, transportation, weather delay etc.

4. $28.02

5. Yes

Step-by-step explanation:

Begin by finding the area of the field. The field is a rectangle and measures 360 by 160. The area is A = l*w = 360*160 = 57,600 square feet. One bag of fertilizer will cover 5000 square feet. Divide 57,600 by 5000 to find the number of bags needed. You'll need 11.52 bags or rounded 12 bags.

Since each bag costs $9.99, multiply 12 by $9.99 to get the total cost for the fertilizer. The cost is $119.88. If the athletic department pays you $300. You'll make 300 - 119.88 = 180.12 for your labor. This is a good profit.

If you have to purchase another tool for $40, then the cost increases to 159.88. This decreases your profit to 180.12 - 40 = 140.12. Divide your profit 140.12 by the 5 hours you work to find how much you earn per hour. You earn $28.02 per hour.

Yes, I would take the job, since $28.02 is well above minimum wage.

Answer:

Answer:

-sinx

Step-by-step explanation:

a trig identity that is crucial to solving this problem is: sin^2 + cos^2 = 1

with knowing that, you can manipulate that and turn it into 1 - sin^2x = cos^x

so 1-sin^2x/sinx - cscx becomes cos^2x/sinx - cscx

it is also important to know that cscx is the same thing as 1/sinx

knowing this information, cscx can be replaced with 1/sinx

(cos^2x)/(sinx - 1/sinx)

now sinx and 1/sinx do not have the same denominator, so we need to multiply top and bottom of sinx by sinx; it becomes....

cos^2x

---------------------

(sin^2x - 1)/sinx

notice how in the denominator it has sin^2x-1 which is equal to -cos^2x

so now it becomes:

cos^2x

--------------

-cos^2x/sinx

because we have a fraction over a fraction, we need to flip it

cos^2x          sinx

---------- * ----------------

1                  -  cos^2x

because the cos^2x can cancel out, it becomes 1

now the answer is -sinx
