Answer:

Step-by-step explanation:

Solve for one variable and substitute the value in to another equation.

Answer:

answer: 105

Step-by-step explanation:

For triangle area you just have to do base × height ÷ 2 So we will do 8 × 5 = 40 then divide by 40 by 2 so 40 ÷ 2 = 20 now we have 1 triangles area we can find the rest because each of these triangles are equal so 20 × 4 = 80 now we just have to do the square so thats easily just base × height so 5 × 5 = 25 now we just add 80 and 25 so 80 + 25 = 105 so 105 is our surface area!

Answer:

(a) The expected value is: $0.40625

(b) The expected value is: $0.4286

Step-by-step explanation:

Solving (a): Raffle 1

Given

[tex]Tickets=800[/tex]

[tex]Value = \$2[/tex] per ticket

[tex]Grand\ Prize = \$450[/tex] ---- for 1

[tex]Consolation = \$100[/tex] --- for 2

Required

The expected value of each ticket

First, calculate the total amount of the 800 tickets

[tex]Amount = Tickets * Value[/tex]

[tex]A_1 = 800 * \$2[/tex]

[tex]A_1 = \$1600[/tex]

Next, calculate the total amount of the prizes

[tex]Amount = Tickets * Value[/tex]

[tex]A_2 = \$450 * 1 +\$100 * 2[/tex]

[tex]A_2 = \$450 +\$200[/tex]

[tex]A_2 = \$650[/tex]

The expected value E(x) of 1 ticket is calculated as:

[tex]E(x) = \frac{A_2}{A_1}[/tex]

[tex]E(x) = \frac{\$650}{\$1600}[/tex]

[tex]E(x) = \$0.40625[/tex]

Solving (b): Raffle 2

Given

[tex]Tickets=350[/tex]

[tex]Value = \$2[/tex] per ticket

[tex]Grand\ Prize = \$150[/tex] ---- for 1

[tex]Consolation = \$50[/tex] --- for 3

Required

The expected value of each ticket

First, calculate the total amount of the 800 tickets

[tex]Amount = Tickets * Value[/tex]

[tex]A_1 = 350 * \$2[/tex]

[tex]A_1 = \$700[/tex]

Next, calculate the total amount of the prizes

[tex]Amount = Tickets * Value[/tex]

[tex]A_2 = \$150 * 1 +\$50 * 3[/tex]

[tex]A_2 = \$150 +\$150[/tex]

[tex]A_2 = \$300[/tex]

The expected value E(x) of 1 ticket is calculated as:

[tex]E(x) = \frac{A_2}{A_1}[/tex]

[tex]E(x) = \frac{\$300}{\$700}[/tex]

[tex]E(x) = \$0.4286[/tex]

Answer:

Hmm, want piña colada and Jar Jar Binks cookies? just go to India.

Answer:

See below directions.

Step-by-step explanation:

The condition [tex]-2\pi<\theta<2\pi[/tex] means you can get to the point by rotating no more than one revolution in either the positive or negative direction.

See the attached image to see the point [tex]\left(3,\,-\frac{3\pi}{4}\right)[/tex].  Think about how you get to that point:  start at the origin, go right (along the positive x-axis) 3 units, then turn in the negative direction (to your right!) through an angle of [tex]\frac{3\pi}{4}[/tex].

Now, go again, starting at the origin, only this time, go 3 units right, then turn through an angle of [tex]-\frac{3\pi}{4}+2\pi=\frac{5\pi}{4}[/tex].  In other words, you turn one whole revolution in addition to the [tex]-\frac{3\pi}{4}[/tex] angle.  Your point can now be described by [tex]\left(3,\,\frac{5\pi}{4}\right)[/tex].

Another description can be found by rotating in the opposite direction, so an angle of [tex]\frac{3\pi}{4}[/tex] and backing up 3 units -- specify a "radius" of -3.  The point is then [tex]\left(-3,\,\frac{3\pi}{4}\right)[/tex].

You can also try subtracting one revolution [tex](2\pi)[/tex] from the angle, but be careful not to let the angle go outside the interval  [tex]-2\pi<\theta<2\pi[/tex].

The changes you can try are:  

add [tex]2\pi[/tex] to the angle, leave r alone

subtract [tex]2\pi[/tex] to the angle, leave r alone

add/subtract [tex]\pi[/tex] (half a revolution) to the angle, make r the opposite.

Answer:

Blank 1; AB

Blank 2; AC

Blank 3; BC

Step-by-step explanation:

Mathematically, the greater the angle that faces a side of a triangle, the bigger the side length of the triangle

so what this mean is that, bigger side lengths faces bigger angles

From the list of angles we have, the side that faces vertex C is the biggest

We have this as;

AB faces C and that is the biggest

the next is the side that faces angle B; we have the length as AC

the least faces angle A ; we have the length as BC

Answer:

180°

Step-by-step explanation:

According to Angle sum property of a triangle , sum of all the three angles of a triangle equals to 180°

Answer:

LSA = 2πrH

Step-by-step explanation:

The lateral surface area of a cylinder is given by the formula as:

LSA = 2πrH

where, r and H are radius and height of the cylinder respectively.

The volume of cylinder is πr^2H

and Total surface are of cylinder = LSA+ 2× base are

= 2πrH +2πr^2

You can substitute any values of r and H to find LSA of the cylinder

Answer:

Amount of commission earned = $225

Step-by-step explanation:

Commission rate = 25%

Sales amount = $900

Find the amount of commission earned by the salesperson

Amount of commission earned = Commission rate × Sales amount

= 25% × $900

= 25/100 × $900

= 0.25 × $900

= $225

Amount of commission earned = $225

Answer: x=25

Step-by-step explanation: equation comes out to

4x+80=180

4x=100

x=25

Answer:

x=25

Step-by-step explanation:

x+30+x+40+2x+10=180

Add the X up together and the other number which will be

4x+80=180

subtract 80 from both sides

4x=100

divide 4 from both sides

x=25

The market price and profit amount if the shopkeeper paid 2500 for the article​ will be 3250 and 11.05%.

Profit is made when the money generated from a commercial operation exceeds the expenses, charges, and taxes associated with operating the activity in question.

Given data;

Purchase price = 2500

Given condition;

The markup is 30% more than the purchasing price.

Mark Price is found as;

[tex]\rm MP = \frac{130}{100}\times 2500 \\\\ MP =130\times 25\\\\ MP=3250[/tex]

The marked price of an article will be 3250.

Since we are aware that discounts usually apply to mark prices, a 15 percent discount is now being offered;

[tex]\rm \frac{85}{100}\times 3250 = 2762.5 RS[/tex]

The profit in the article is found as;

Profit = 2762.5-2500

Profit = 226.25 RS

Now profit % is found as;

[tex]\% profit = \frac{276.25}{2500}\times 100 \\\\ \% profit = 11.05 \%[/tex];

Hence, the market price and profit amount, if the shopkeeper paid 2500 for the article,​ will be 3250 and 11.05%.

Answer:

2√2 = x

Step-by-step explanation:

x

---- = sin 45 degrees, or

4

 x        1

----- = -----

 4       √2

this results in x = 4 / √2  =  4√2/2  =  2√2 = x

The value of the variable 'x' will be 2√2 units. Then the correct option is C.

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

The two triangular legs and their opposing angles are congruent in an isosceles triangle.

The triangle is an isosceles right-angle triangle. Then by the Pythagoras theorem, we have

4² = x² + x²

2x² = 16

x² = 8

x = 2√2

The value of the variable 'x' will be 2√2 units. Then the correct option is C.

Answer: 45

Step-by-step explanation:

Hello there!

So this problem looks a lot more complex than it really is. First, we need to know that a straight line is 180 degrees. Since both of these angles must add up to 180, we just subtract 135 from 180. We then get 45.

Answer:

2 cups of clay

Step-by-step explanation:

Given data

we are given that  6 cups of water for every 12 cups of clay

  i.e

12 cups of clay require 6 cups of water

4 cups of clay will require x cups of water

cross multiply

12x= 4*6

12x= 24

divide both sides  by 12

x= 24/12

x= 2cups

Hence 4 cups of water will require 2 cups of clay
