Answer:

Distance from point A(0,5) to y = -3 x  - 5 is √10 units units.

Step-by-step explanation:

Here, the given line equation is  y = -3x -5

Also, the point A (0,5) is the given point.

Now, a distance of a point (m,n)  from a line Ax + By + c = 0 is given as:

[tex]d = \frac{\mid Am +bn+c \mid}{\sqrt{A^2 + B^2} }[/tex]

Here, the equation is  y = -3 x -5

⇒ 3 x + y + 5 = 0  , here A  = 3, B = 1

Now, the value of line equation at (0,5) is  3(0) + 5 + 5 = 10

So, from the given distance formula,  we get:

[tex]d = \frac{\mid Am +bn+c \mid}{\sqrt{A^2 + B^2} }  = d = \frac{10}{\sqrt{(3)^2 + (1)^2} } = \frac{10}{\sqrt{(10)}}   = \sqrt{(10)}[/tex]

⇒ d  = √10 units

Hence, distance from point A(0,5) to y = -3 x  - 5 is √10 units units.

To find the distance from point A(0,5) to the line y=-3x-5, we can use the distance formula.

To find the distance from point A(0,5) to the line y=-3x-5, we can use the distance formula.

The distance formula is given by:

d = √((x2 - x1)² + (y2 - y1)²)

In this case, point A is (0,5) and the line is y = -3x - 5.

So, we can substitute the values into the formula:

d = √((x - 0)² + (y - 5)²)

d = √(x² + (y - 5)²)

To find the distance, we need to substitute the x and y values of a point on the line into the formula and solve for d.

Let's take the point (1, -8) as an example:

d = √((1)² + (-8 - 5)²)

d = √(1 + 169)

d = √170

So, the distance from point A(0,5) to the line y=-3x-5 is √170.

Time left for Madison for other activities is [tex]\frac{5x}{12}[/tex] h .

Step-by-step explanation:

Given as :

The time reserved by Madison for activities = x hours

The time uses for basketball = [tex]\frac{1}{4}[/tex] of x = [tex]\frac{x}{4}[/tex] h

The time uses for playing saxophone = [tex]\frac{1}{3}[/tex] of x = [tex]\frac{x}{3}[/tex] h

So , The total time used by him = [tex]\frac{x}{4}[/tex] h +  [tex]\frac{x}{3}[/tex] h

I.e The total time used by him =  [tex]\frac{7x}{12}[/tex] h

Now, The time left for other activities = x h -   [tex]\frac{7x}{12}[/tex] h

I.e  The time left for other activities =  [tex]\frac{12x - 7x}{12}[/tex] h

or,  The time left for other activities =  [tex]\frac{5x}{12}[/tex] h

Answer:

x=27°

Step-by-step explanation:

we know that

The Triangle Exterior Angle Theorem, states that: An exterior angle of a triangle is equal to the sum of the opposite interior angles

step 1

Find the measure of angle PLM

we know that

m∠PLM+m∠LPM=m∠PMN ----> by Triangle Exterior Angle Theorem

we have

m∠LPM=x°

m∠PMN=2x+72°

substitute

m∠PLM+x=2x+72°

m∠PLM=2x-x+72°

m∠PLM=x+72°

step 2

Find the measure of angle x

we know that

3x+m∠PLM=180° ----> by supplementary angles (form a linear pair)

we have

m∠PLM=x+72°  (see step 1)

substitute

3x+x+72°=180°

4x=180°-72°

4x=108°

x=27°

Answer:

By the given diagram,

PLM is a triangle,

K and N are points on line MN,

m∠KLP = 3x, m∠P = x, m∠PMN = 2x + 72°

We need to give the reasons in the steps of finding the value of x.

For this we have to know the following properties :

Linear pairs: Adjacent angles which are supplementary.

Subtraction property of equality : We can subtract a number or expression in both sides of an equation.

i.e. a = b ⇒ a + c = b + c

Exterior angle theorem : exterior angle formed by extending the side of a triangle is equal to the sum of its non-adjacent angles.

Thus, the steps of finding value of x are as follow,

1. m∠KLP+m∠PLM = 180°       ( linear pairs )

2. 3x +m∠PLM = 180°              ( Substitution)

3. m∠PLM = 180° - 3x              ( Subtraction property of equality)

4. m∠PMN=m∠P+m∠PLM      ( Exterior angle theorem )

5. 2x + 72° = x + 180° - 3x        ( Substitution)

6. 2x + 72° = 180° - 2x              ( Solving )

   2x = 180° - 2x - 72°  

   2x + 2x = 108°

   4x = 108°

   x   = 27°

Answer:

In the Pascal Expansion of [tex](x+3)^4[/tex] the third term is [tex]54x^2[/tex].

Step-by-step explanation:

Here, the given expression is given as [tex](x+3)^4[/tex]

Now, by the PASCAL'S TRIANGLE EXPANSION:

[tex](a + b)^4 = 1(a)^4 + 4(a)^3b + 6(a)^2b^2 + 4(a)b^3 + 1b^4\\= 1 + 4b + 6a^2 + 4b^3 + b^4.[/tex]

Substituting a  = x and b = 3, we get:

[tex](x + 3)^4 = 1(x)^4 + 4(x)^3(3) + 6(x)^2(3)^2 + 4(x)(3)^3 + 1(3)^4\\= x^4 + 12x^3 + 54x^2  + 108x+ 81[/tex]

In the given expansion, the third term is [tex]54x^2[/tex].

Hence, in the Pascal Expansion of [tex](x+3)^4[/tex] the third term is [tex]54x^2[/tex].

Final answer:

The third term is 6 times x squared times 3 squared, which simplifies to 54x².

Explanation:

To use Pascal's Triangle to determine the third term of the expansion of (x + 3)⁴, we first need to look at the row of Pascal's Triangle that corresponds to the exponent 4. This is the fifth row if we start counting from 0 and it reads 1, 4, 6, 4, 1. We use these coefficients for each term of the expansion, which follows the pattern (a + b)ⁿ = C(n,0)*aⁿ + C(n,1)*a⁽ⁿ⁻¹⁾b + C(n,2)*a⁽ⁿ⁻²⁾b² + ... + C(n,n)*bⁿ, where C(n,k) is the binomial coefficient from Pascal's Triangle.

So, the third term in the expansion is given by the third coefficient (counting from 0) from the row, which is 6, multiplied by x raised to power 4 - 2 times 3 squared. Therefore, the third term is 6x²·3², which simplifies to 54x².

Answer:

57

Step-by-step explanation:

The bottom line of the triangle is 180 degrees. Therefore, 2y + 4y - 36 has to equal 180. So, once you solve this linear equation, you will find that y equals 36. A triangle's angles always equal a total of 180 degrees. So, x + 51 + 2y has to equal 180, as well. Since we know y, substitute in 36 for 2y. Now the equation is 51 + 72 + x = 180. Solve for x. X is 57.

Answer:

57°

Step-by-step explanation:

The angles that are at the bottom middle are on a straight line, so they must add up to 180°. In order to determine y, use the equation 180 = 2y + 4y -36. After solving for y, you should be left with 36 = y. Now, we can fill in the bottom right angle in the left triangle. This would be 36 times 2, or 72. In triangles, all angles always add up to 180°, so, we can use the equation 180 = x + 51 + 72. Once solved for x, this will leave you with 57 = x, our final answer.

The diameter of the circle is B) 24 inches.

Step-by-step explanation:

The value given (12 inches) is the radius of the circle. The diameter of a circle is equal to 2 * radius. 2 * 12 = 24.

The diameter of the circle is 24 inches.

Option B is the correct answer.

We have,

The diameter of a circle is a line segment that passes through the center of the circle and connects two points on its circumference.

It is the longest chord of the circle and divides the circle into two equal halves.

The diameter is commonly denoted by the symbol "d" and is related to the radius of the circle (denoted by "r") by the equation:

d = 2r

Now,

r = 12 inches

So,

d = 2r = 2 x 12 inches

d = 24 inches

d = 24 inches

Thus,

The diameter of the circle is 24 inches.

Number of adult tickets sold = 17

Number of student tickets sold =32

Number of senior citizen tickets sold = 51

Given that a certain school sells:

adult tickets = $ 8 ; student tickets = $ 5 and senior citizen tickets = $ 6

Let the number of adult tickets sold be "a"

Let the number of student tickets sold be "b"

Let the number of senior citizen tickets sold be "c"

For one game 100 tickets were sold for $ 600

Number of adult tickets sold + number of student tickets sold + number of senior citizen tickets sold = 100

a + b + c = 100 ------ eqn 1

Number of adult tickets sold  x price of one adult ticket +  number of student tickets sold x  price of one student tickets +  number of senior citizen tickets sold x price of one senior citizen tickets = 600

8a + 5b + 6c = 600  ----- eqn 2

There are 3 times as many adult tickets sold as senior citizen tickets

Hence we get,

3a = c  -------- eqn 3

Put eqn 3 in eqn 1 we get,

a + b + 3a = 100

4a + b = 100

b = 100 - 4a  ----- eqn 4

Substitute eqn 3 and eqn 4 in eqn 2, we get

8a + 5(100 - 4a) + 6(3a) = 600

8a + 500 - 20a + 18a = 600

6a = 600 - 500

a = 16.67 that is approximately 17

a = 17

Substitute a = 17 in eqn 3,

3(17) = c

c = 51

Substitute a = 17 in eqn 4,

b = 100 - 4(17) = 100 - 68 = 32

b = 32

you want it to be in minutes, so calculate the 45 seconds over 60 seconds, which is 0.75. Add that to the 4 minutes, and divide the total number of copies over the time used, and you have speed/minute.

To find how many copies the machine makes per minute, we convert the total time to minutes (4 minutes and 45 seconds equals 4.75 minutes) and then divide the number of copies (171) by this time, resulting in 36 copies per minute.

To calculate how many copies the machine makes per minute, we need to convert 4 minutes and 45 seconds into minutes. Since there are 60 seconds in a minute, 45 seconds is the same as 0.75 minutes (45/60). Adding this to 4 minutes gives us a total time of 4.75 minutes for the machine to make 171 copies. Now, to find the copies made per minute, we divide the number of copies by the number of minutes:

Copies per minute = Total copies / Total time in minutes

= 171 copies / 4.75 minutes

= 36 copies per minute.

The chemist should use 86.13 liters of the 15% solution,

47.29 liters of the 35% solution,

94.58 liters of the 65% solution to obtain a mixture of 228 liters containing 25% acid, using 2 times as much of the 65% solution as the 35% solution.

To solve this problem, we need to find how many liters of each solution should be used to obtain a mixture of 228 liters containing 25% acid, using 2 times as much of the 65% solution as the 35% solution. Here's how we can approach the problem:

Let's assume that we need to use x liters of the 15% solution, y liters of the 35% solution, and z liters of the 65% solution.

From the problem statement, we know that:

x + y + z = 228 (since we need a total of 228 liters of the mixture)

z = 2y (since we need to use 2 times as much of the 65% solution as the 35% solution)

0.15x + 0.35y + 0.65z = 0.25(228) (since we need the final mixture to contain 25% acid)

We can use these equations to solve for x, y, and z. Here's how:

Substitute z = 2y into the first equation to get x + y + 2y = 228, which simplifies to x + 3y = 228.

Rearrange this equation to get x = 228 - 3y.

Substitute z = 2y into the second equation to get 0.15x + 0.35y + 0.65(2y) = 0.25(228), which simplifies to 0.15x + 1.15y = 74.4.

Substitute x = 228 - 3y into this equation to get 0.15(228 - 3y) + 1.15y = 74.4, which simplifies to 34.2 - 0.3y = 74.4 - 1.15y.

Rearrange this equation to get 0.85y = 40.2, which simplifies to y = 47.29.

Substitute y = 47.29 into z = 2y to get z = 94.58.

Substitute y = 47.29 and z = 94.58 into x + 3y = 228 to get x = 86.13.

Therefore, the chemist should use 86.13 liters of the 15% solution, 47.29 liters of the 35% solution, and 94.58 liters of the 65% solution to obtain a mixture of 228 liters containing 25% acid, using 2 times as much of the 65% solution as the 35% solution.
