Answer:

x = 34

Step-by-step explanation:

The 3 given angles form a straight angle and sum to 180°, hence

x + 12 + 100 + x = 180

2x + 112 = 180 ( subtract 112 from both sides )

2x = 68 ( divide both sides by 2 )

x = 34

Answer:

x=34

Step-by-step explanation:

Alright.

x+12+100+x=180

         2x+112=180

                2x=68

                   x=34

Answer:

Step-by-step explanation:

No solution means that the 2 lines will never intersect in a coordinate plane.  The only kinds of lines that can exist within the same coordinate plane and never intersect are lines that are parallel.  The slopes have to be the same for lines to be parallel.  The y-intercept, or where they go through the y axis, won't be the same, but the value of the slope has to be.  The slope of the equation on the right is 33, so if these lines are parallel, then Q has to equal 33.  P can then be any real number NOT equal to 25.

[tex]\dfrac{a^2}{b}[/tex] is an integer, where [tex]a,b\in\mathbb{Z_+}[/tex], therefore [tex]b|a^2[/tex] and [tex]b\leq a^2[/tex]

[tex]a=pq[/tex] therefore [tex]a^2=p^2q^2[/tex]

[tex]b>a\wedge b\leq a^2[/tex], therefore [tex]pq<b\leq p^2q^2[/tex]

So,

[tex]b\in\{p^2q,pq^2,p^2q^2\} \\|\{p^2q,pq^2,p^2q^2\}|=3 \implies \text{B}[/tex]

Answer:

x = 3.1 ft

Step-by-step explanation:

Use Pythagoras' Theorem to find the base of the triangle. The base of the triangle is half of 'x'. Let's call the base 'y' for now.

To find 'y' we must use this formula,

[tex]y^{2} = c^{2} -b^{2}[/tex]

'c' is the hypotenuse, the longer side, and 'b' is the other short side.

Sub in the numbers for 'c' and 'b',

[tex]y^{2} = 2.1^{2} -1.4^{2}[/tex]

               = 2.45

Square root both sides to get 'y' by itself,

y = 1.5652.....

Remember that 'y' is half of x? Simply multiply 'y' by 2 to get an answer for 'x',

x = 1.5652.... x 2

  = 3.1 ft (1 d.p. nearest tenth)

The formula for the area of a rectangle is...

Area = length x width

A = L x W

What we know so far...

Area is 590 cm^2

length is 12 cm

width is unknown

Plug all of these into the equation for area of a rectangle:

590 = 12 * w

or

590 = 12w

Letter A is the correct answer

Hope this helped!

Answer:

The correct answer is B. The number of rides and the total cost are both dependent variables, as both depend on the amount of money that Nia has.

Step-by-step explanation:

Both the number of rides and the total cost are variables that depend on the amount of money that Nia has. This is so because the passage has a cost, and that cost can not exceed the amount of money that Nia has, because if she exceeds her $ 19.50 she won't be able to pay the ticket. Then, Nia has a possible amount of 26 rides as maximum (19.5 / 0.75 = 26), and the maximum total cost that can be paid is $ 19.50.

Final answer:

The correct answer is: C) The number of rides is the independent variable, and the total cost is the dependent variable.

Explanation:

In the scenario where Nia has $19.50 to ride the subway around New York, at a cost of $0.75 per ride, the correct identification of the dependent and independent variables is crucial for understanding the relationship between these quantities.

The independent variable is the number of rides Nia can take. This is because it is the variable over which we have control or can set at different levels; in other words, Nia decides how many trips she takes.

The dependent variable is the total cost of these rides. The cost depends on how many rides she takes, changing accordingly with that number.

Therefore, the correct answer is: C) The number of rides is the independent variable, and the total cost is the dependent variable.

Answer:

[tex]2x + 50,000 \ge 70,000[/tex].

[tex]x \ge 10,000[/tex].

Step-by-step explanation:

What's the total income of Ms. Wolf in a year?

The annual income of Ms. Wolf comes in two parts:

How many commission does Ms. Wolf receive for each share she sold? [tex]\$\;50 \times 4\% = \$\;50 \times 0.04 = \$\;2[/tex].

Let the number of shares that Ms. Wolf sold be [tex]x[/tex]. Ms. Wolf will receive a commission of [tex]\$\;2x[/tex].

Total annual income of Ms. Wolf: [tex]\$\; (50,000 + 2x)[/tex].

The phrase "at least" indicates that [tex]\$\; (50,000 + 2x)[/tex] shall be greater than or equal to $70,000. That is:

[tex]\$\; (50,000 + 2x)\ge \$\;70,000[/tex].

[tex]2x + 50,000 \ge 70,000[/tex].

[tex]x \ge 20,000[/tex].

Answer:

13/18

Step-by-step explanation:

We need to get a common denominator for 9,6,3

That would be 18

5/9 *2/2 = 10/18

5/6 * 3/3 = 15/18

2/3 *6/6 = 12/18

5/9+5/6 = 10/18 +15/18 = 25/18

Then

25/18 - 2/3 = 25/18 - 12/18 = 13/18

Answer:

Cost of yard silk fabric : $35

Cost of yard of woolen fabric: $60

Step-by-step explanation:

This problem must be represented as a linear system of equations

Let

x = the cost of 1 yard of woolen fabric

y = the cost of 1 yard of silk fabric

The problem tells us

4 yards of woolen fabric costs $30.00 more than 6 yards of silk fabric.

4.x = 6.y + 30

cost of the silk is $25.00 less than the cost of the wool

y = x - 25

The system of equations is

4x - 6y =  30

x - y  = 25

If we solve this system of equations using a calculator or computational tool, we get the following values

x = $60

y = $35

Two events A and B are independent when

[tex]Pr(A\cap B)=Pr(A)\cdot Pr(B)[/tex]

a) A="Chocolate"

B="Adults"

A and B="Chocolate and Adults"

[tex]Pr(A)=0.35\\ \\Pr(B)=0.60\\ \\Pr(A\cap B)=0.21[/tex]

Since [tex]0.35\cdot 0.60=0.21[/tex] events are independent

b) A="Children"

B="Chocolate"

A and B="Children and Chocolate"

[tex]Pr(A)=0.40\\ \\Pr(B)=0.35\\ \\Pr(A\cap B)=0.14[/tex]

Since [tex]0.40\cdot 0.35=0.14[/tex] events are independent

c) A="Vanilla"

B="Children"

A and B="Vanilla and Children"

[tex]Pr(A)=0.65\\ \\Pr(B)=0.40\\ \\Pr(A\cap B)=0.26[/tex]

Answer:

  D.  (x-5)^2 = 36

Step-by-step explanation:

If you add 11 to the given equation, you get ...

  x^2 -10x = 11

Then you can add the square of half the x-coefficient to complete the square.

  x^2 -10x +25 = 11 +25

  (x -5)^2 = 36 . . . . simplify to the appropriate form

The answers are:

[tex]MaximumDistance=1200.1ft\\MinimumDistance=1199.9ft[/tex]

Since we are given the margin of error and it's equal to ±0.1 feet, and we know the surveyed distance, we can calculate the maximum and minimum distance. We must remember that margin of errors usually involves and maximum and minimum margin of a measure, and it means that the real measure will not be greater or less than the values located at the margins.

We know that the surveyed distance is 1200 feet with a margin of error of ±0.1 feet, so, we can calculate the maximum and minimum distances that the reader could assume in the following way:

[tex]MaximumDistance=ActualDistance+0.1feet\\\\MaximumDistance=1200feet+0.1feet=1200.1feet[/tex]

[tex]MinimumDistance=ActualDistance-0.1feet\\\\MaximumDistance=1200feet-0.1feet=1199.9feet[/tex]

Rewriting .125 as .5^3

( .5^3) ^1/3 ( b^3) ^ 1/3

We know that a^c^d = a^(c*d)

.5 ^ (3*1/3)   b ^ (3*1/3)

Answer:

if u can divide it to two

Step-by-step explanation:

The green square is 15 ft wide by 15 ft tall.

The area of one green square is 15 x 15 = 225 square feet.

There are 4 sides plus the base : 225 x 5 = 1125 square feet for the green part.

One triangle has a base 15 feet wide and a height of 9 feet.

The area for one triangle is 1/2 x 15 x 9 = 67.5 square feet.

There are 4 triangles: 67.5 x 4 = 270 square feet.

Total: 1125 + 270 = 1,395 square feet.

Answer:

  6 yards by 11 yards

Step-by-step explanation:

Factors of 66 are ...

  66 = 1·66 = 2·33 = 3·22 = 6·11

The last pair of factors differ by 5, so represent the solution to the problem.

The width of the parking lot is 6 yards; the length is 11 yards.

Final answer:

The parking lot's dimensions are found by setting a quadratic equation w × (w + 5) = 66 based on its area. Solving for w, the width is 6 yards, hence the length is 11 yards, making the dimensions 6 yards by 11 yards.

Explanation:

To find the dimensions of the parking lot when the length is 5 yards more than the width and the area is 66 square yards, we can set up an equation based on the area of a rectangle (area = length × width). We can define the width as w and the length as w + 5 since the length is 5 yards more than the width.

The equation representing the area will then be:

w × (w + 5) = 66

Solving this quadratic equation (w^2 + 5w - 66 = 0) by factoring or using the quadratic formula, we find that w = 6 or w = -11. We discard the negative value since a width cannot be negative, so the width is 6 yards and the length is 11 yards (since it's 5 yards more than the width).

Therefore, the dimensions of the parking lot are 6 yards by 11 yards.

let's firstly convert the mixed fractions to improper fractions and then divide.

[tex]\bf \stackrel{mixed}{6\frac{1}{2}}\implies \cfrac{6\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{13}{2}}~\hfill \stackrel{mixed}{1\frac{5}{8}\implies \cfrac{1\cdot 8+5}{8}}\implies \stackrel{improper}{\cfrac{13}{8}} \\\\[-0.35em] ~\dotfill[/tex]

Answer:

x=225

Step-by-step explanation:

\sqrt{x} + (-13 + 13) = 2 + 13

\sqrt{x} = 15

√x-13=2

x=225

If you meant to write...

[tex]\sqrt{x - 13} = 2[/tex]

Then the following is the answer:

To solve this you must get rid of the square root. The opposite of square root is square. You must square both sides since what you do to one side you must do to the other...

([tex]\sqrt{x-13} )^{2}[/tex] = [tex]2^{2}[/tex]

x - 13 = 4

Finish completely isolating x. To do this first add 13 to both sides (what you do on one side you must do to the other). Since 13 is being subtracted, addition (the opposite of subtraction) will cancel it out (make it zero) from the left side and bring it over to the right side.

x + (-13 + 13) = 4 + 13

x + 0 = 17

x = 17

If you meant to write...

[tex]\sqrt{x}[/tex] - 13 = 2

Then the following is the answer:

To isolate [tex]\sqrt{x}[/tex]. To do this first add 13 to both sides (what you do on one side you must do to the other). Since 13 is being subtracted, addition (the opposite of subtraction) will cancel it out (make it zero) from the left side and bring it over to the right side.

[tex]\sqrt{x}[/tex] + (-13 + 13) = 2 + 13

[tex]\sqrt{x}[/tex] = 15

To completely isolate x you must get rid of the square root. The opposite of square root is square. You must square both sides since what you do to one side you must do to the other...

[tex](\sqrt{x})^{2} = 15^{2}[/tex]

x = 225

Area of a triangle = height x base ÷ 2

When ever you have an isosceles triangle, remember that you can split it in half to form two right angled triangles - which allow you to use Pythagoras' Theorem.

So we split 10cm in half to get 5cm.

We can then use 13cm and 5cm to work out the height:

Height = √(13²  - 5²)      (Note: you subtract because you are using the    

           = √144              (hypotenuse)

           =  12

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

Now to get the area, we just multiply the base (which is 10) by the height (which is 12) and divide by 2:

Area = 12 x 10 ÷ 2

        = 6 x 10               (note: 12 ÷ 2 = 6 )

        = 60 cm²

5 but its probaly not right bc im just looking for pointsStep-by-step explanation:

Answer:

Part 1) [tex]y=-x^{2}[/tex]  ---> Translated up by 1 units

Part 2) [tex]y=x^{2}+1[/tex]  ---> Reflected across the x-axis

Part 3) [tex]y=-(x+1)^{2}-1[/tex]  ---> Translated left by 1 unit

Part 4) [tex]y=-(x-1)^{2}-1[/tex] ----> Translated right by 1 unit

Part 5) [tex]y=-x^{2}-1[/tex]  ----> Reflected across the y-axis

Part 6) [tex]y=-x^{2}-2[/tex]  ----> Translated down by 1 unit

Step-by-step explanation:

we know that

The parent function is

[tex]y=-x^{2}-1[/tex] ----> this is a vertical parabola open downward with vertex at (0,-1)

Calculate each case

Part 1) Translated up by 1 unit

The rule of the translation is

(x,y) -----> (x,y+1)

so

(0,-1) ----> (0,-1+1)

(0,1) ----> (0,0) ----> the new vertex

The new function is equal to

[tex]y=-x^{2}[/tex]

Part 2) Reflected across the x-axis

The rule of the reflection is

(x,y) -----> (x,-y)

so

(0,-1) ----> (0,1) ----> the new vertex

The new function is equal to

[tex]y=x^{2}+1[/tex]

Part 3) Translated left by 1 unit

The rule of the translation is

(x,y) -----> (x-1,y)

so

(0,-1) ----> (0-1,-1)

(0,1) ----> (-1,-1) ----> the new vertex

The new function is equal to

[tex]y=-(x+1)^{2}-1[/tex]

Part 4) Translated right by 1 unit

The rule of the translation is

(x,y) -----> (x+1,y)

so

(0,-1) ----> (0+1,-1)

(0,1) ----> (1,-1) ----> the new vertex

The new function is equal to

[tex]y=-(x-1)^{2}-1[/tex]

Part 5) Reflected across the y-axis

The rule of the reflection is

(x,y) -----> (-x,y)

so

(0,-1) ----> (0,-1) ----> the new vertex

The new function is equal to

[tex]y=-x^{2}-1[/tex]

Part 6) Translated down by 1 unit

The rule of the translation is

(x,y) -----> (x,y-1)

so

(0,-1) ----> (0,-1-1)

(0,1) ----> (0,-2) ----> the new vertex

The new function is equal to

[tex]y=-x^{2}-2[/tex]
