Answer: Take-Home Pay is the money a person has after paying off all the things that are forced, like taxes.

Step-by-step explanation: There is none. It's English.

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.

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).

Answer:

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:

-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

Remove parentheses                          = sec²x - 1

Use the identity: tan²x  + 1 = sec²x     = tan²x + 1 - 1

                                                             = tan²x

tan²x = (secx - 1)(secx + 1)

Answer:  The required answer is tan x.

Step-by-step explanation:  We are given to complete the following trigonometric identity :

[tex](\_\_\_\_\_)^2=(\sec x-1)(\sec x+1).[/tex]

We will be using the following identity from trigonometry to complete the given identity :

[tex]1+\tan^2\theta=\sec^2\theta\\\\\Rightarrow \sec^2\theta-1=\tan^2\theta~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

Now, we have

[tex](\sec x-1)(\sec x+1)\\\\=\sec^2x-1\\\\=\tan^2x~~~~~~~~~~[\textup{from equation (i)}]\\\\=(\tan x)^2.[/tex]

Thus, the complete identity is

Here's what a net of a cuboid looks like if that was what you were asking.

Final answer:

The question involves identifying a net for a cuboid, which is a two-dimensional arrangement of rectangles that can be folded into a three-dimensional box shape.

Explanation:

The subject of the question is identifying a net of a cuboid. A net is a two-dimensional shape that can be folded to form a three-dimensional object. In the case of a cuboid, its net consists of 6 rectangles that correspond to the faces of the cuboid: top, bottom, front, back, and two sides. To create a net, you would draw these 6 rectangles in such an arrangement that when the edges are folded up, they would form the sides of a cuboid. The question requires understanding of basic geometry and how two-dimensional shapes can construct three-dimensional forms.

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:

the answer is 25

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.

The answer would be D and E

The following statements that are true: m1 + m2 + m 3 = 180 and 1 and 4 are vertical angles.

Statement A is false. Angles 2 and 3 are not adjacent to each other, so they do not form a linear pair.

Statement B is false. Supplementary angles add up to 180 degrees, but angles 1 and 4 do not add up to 180 degrees.

Statement C is true. The sum of the measures of the angles in a triangle is 180 degrees. Therefore, the sum of the measures of angles 1, 2, and 3 is 180 degrees.

Statement D is false. Angles 3 and 4 are not opposite each other, so they are not vertical angles.

Statement E is true. Vertical angles are opposite each other, and angles 1 and 4 are opposite each other. Therefore, angles 1 and 4 are vertical angles.

[tex]20.11\ cm[/tex]

Step-by-step explanation:

we know that

The surface area of the cone is equal to

[tex]SA=\pi r^{2}+\pi rl[/tex]

where

r is the radius

l is the slant height

In this problem we have

[tex]SA=822.78\ cm^{2}[/tex]

[tex]r=18/2=9\ cm[/tex] -----> the radius is half the diameter

substitute and solve for l

[tex]822.78=\pi (9)^{2}+\pi (9)l[/tex]

[tex]822.78=81\pi +9\pi l[/tex]

[tex]l=(822.78-81\pi)/9\pi[/tex]

[tex]l=(822.78-81(3.14))/9(3.14)=20.11\ cm[/tex]

The slant height of the cone is approximately 20.1154 cm.

[tex]\[ \text{Surface Area} = \pi r (l + r) \][/tex]

where r is the radius of the base of the cone, and l is the slant height of the cone.

Given that the diameter of the cone is 18 cm, we can find the radius r by dividing the diameter by 2:

[tex]\[ r = \frac{diameter}{2} = \frac{18 \text{ cm}}{2} = 9 \text{ cm} \][/tex]

Now we can substitute the values we know into the surface area formula:

[tex]\[ 822.78 \text{ cm}^2 = \pi \times 9 \text{ cm} \times (l + 9 \text{ cm}) \][/tex]

To find l, we need to solve for l in the equation:

[tex]\[ 822.78 \text{ cm}^2 = 9 \pi \text{ cm} \times (l + 9 \text{ cm}) \] \[ \frac{822.78 \text{ cm}^2}{9 \pi \text{ cm}} = l + 9 \text{ cm} \] \[ \frac{822.78}{9 \pi} = l + 9 \] \[ l = \frac{822.78}{9 \pi} - 9 \][/tex]

Now we calculate the value of l:

[tex]\[ l = \frac{822.78}{9 \times \pi} - 9 \] \[ l = \frac{822.78}{28.27433388} - 9 \] \[ l \approx 29.1154 - 9 \] \[ l \approx 20.1154 \text{ cm} \][/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.
