Answer:

Step-by-step explanation:

There are two other important distances on a circle, the radius (r) and the diameter (d). The radius, the diameter, and the circumference are the three defining aspects of every circle. Given the radius or diameter and pi you can calculate the circumference. The diameter is the distance from one side of the circle to the other at its widest points. The diameter will always pass through the center of the circle. The radius is half of this distance. You can also think of the radius as the distance between the center of the circle and its edge.

This diagram shows the circumference, diameter, center, and radius on a circle.

Answer: A or B but really A

Step-by-step explanation:

c² = 144/169

√c² = √144/169

c = 12/13

  or

-12/13² = 144/169

Hope that helped! I recommend choosing A

The solutions to the equation c² = 144/169 are c = 12/13 and c = -12/13, as they satisfy the equation when substituted into it. Thus, options A and B are the correct answers.

The equation is given as follows:

c² = 144/169

To find the solutions of the equation c² = 144/169, we can take the square root of both sides of the equation.

√(c² = ±√(144/169)

Since the square root of a number can be positive or negative, we have two possibilities for the solutions:

c = ±√(144/169)

Simplifying the square root of 144/169 gives:

c = ±(12/13)

So, the solutions to the equation are:

A) c = 12/13

B) c = -12/13

Therefore, options A and B are the correct answers.

Answer:

11 pints of milk the Garcia family have left after lunch.

Step-by-step explanation:

The Garcia family started the day with 2 gallons of milk.

They drank 1 quart of milk for breakfast and 3 pints for lunch.

Since, 1 gallon = 8 pint

2 gallon = 16 pint

and 1 quart = 2 pint

Left amount = 16 pint - ( 2pint + 3pint)

= 16-5

= 11 pints

Hence, 11 pints of milk the Garcia family have left after lunch.

Answer:

It is the third one.

Step-by-step explanation:

Since the question is asking us that h(x) represents the height of the bridge the answer can be determined.

There are 16 more stamps from France than Germany.

Option A is the correct answer.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Scott's stamp collection:

Germany = 59

Spain = 53

France = 75

The difference between the number of stamps between Germany and France.

= 75 - 59

= 16

Thus,

There are 16 more stamps from France than Germany.

Answer:

Number of necklaces = 8

Number of bracelets = 20

Step-by-step explanation:

Given that:

Mellisa is making and selling the necklaces and bracelets.

Number of pieces of jewelry made on one day = 28

Number of bracelets was 4 more than the twice the number of necklaces.

To find:

Number of each type of jewelry made = ?

Solution:

Let number of bracelets = [tex]b[/tex]

Let number of necklaces = [tex]n[/tex]

As per question statement:

[tex]b+n=28[/tex] ...... (1)

[tex]b = 2n+4[/tex] ...... (2)

Putting the value of [tex]b[/tex] in equation (1):

[tex]2n+4+n=28\\\Rightarrow 3n = 28-4\\\Rightarrow 3n = 24\\\Rightarrow n =\bold{8}[/tex]

By equation (1):

[tex]b + 8 =28\\\Rightarrow b = \bold{20}[/tex]

So, the answer is:

Number of necklaces = 8

Number of bracelets = 20

Answer:

Step-by-step explanation:

use known angles and rules to find unknown values

vertical angles (pairs of angles on opposite sides of an intersection) are equivalent

supplementary angles (angles found next to each other on a line) add up to 180 degrees

opposite interior angles are equivalent

And I don't remember the name of this kind of angle, but angle 1 and 10 are equivalent because they are found on the same "location"

using these rules you can find all missing angles.

1= 75

2=180-75=105

Coordinates of point B':

B' = (-1, -4)

Explanation

To reflect a point or a figure across the x-axis we use the rule:

→

In other words, we multiply the y-coordinate of our points by -1, while leaving the original x-coordinate as it is.

Let's apply the rule to every point of our triangle :

A = (2, 1)

A' = (2, 1*-1) = (2, -1)

B = (-1, 4)

B' = (-1, 4*-1) = (-1, -4)

C = (3, 7)

C' = (3, 7*-1) = (3, -7)

Answer:

r - 18

Step-by-step explanation:

Less than means you put the 18 behind the r

Less than means subtraction

The expression for the phrase 18 less than the number r is r - 18.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

18 less than a number r.

Number = r

This means,

r - 18

Thus,

The expression is r - 18.

Answer:

x = 2

Step-by-step explanation:

Both equations are equal to y, so they're also equal to each other.  We then set them equal to each other:

x^2 - 2x + 1  =  x^2 + 2x - 7

We now do algebra to isolate x.  Subtract 1 from both sides.

x^2 - 2x  =  x^2 + 2x - 8

Subtract 2x from both sides.

x^2 - 4x  =  x^2 - 8

Subtract x^2 from both sides.

-4x = -8

Divide both sides by -4.

x = 2

Answer:

x = 4 , y = 2

Step-by-step explanation:

3x+9y = 30 --------- (1)

2(3x+9y)+x = 64 ---------(2)

substitute (1) into (2)

2(30)+x = 64

60+x = 64

x = 64-60

x = 4

substitute x=4 into (1)

3x+9y = 30

3(4)+9y = 30

12+9y = 30

9y = 30-12

9y = 18

y = 18/9

y = 2

thus, x = 4 and y = 2

Answer:

68 degrees

Step-by-step explanation

If <3 and <4 are vertical angles, then <3 = <4

This means that

9x + 5 = 5x + 33

9x - 5x  = 33 - 5

4x = 28

x = 28/4

x = 7

Since <4 = 5x+ 33

<4 = 5(7) + 33

<4 = 35 + 33

<4 = 68 degrees

Hence the measure of <4 is 68 degrees

Answer:

S = (-4, -34)

Step-by-step explanation:

T=(10, 18) is one end of the segment

the midpoint is located at (5, -8)

therefore, using the formula for midpoint, we can find the other end of the segment (point S)

Midpoint x-value = xa + (xb - xa)/2

in our case;

5 = 10 + (xb-10)/2

3 - 10 = (xb-10)/2

-7 = (xb-10)/2

-14 = xb-10

xb = -14 + 10 = - 4

Now for the y value of the midpoint:

Midpoint y-value = ya + (yb - ya)/2

in our case:

-8 = 18 + (yb - 18)/2

- 26 = (yb - 18)/2

- 52 = yb - 18

yb = -52 + 18 = -34

Then. point S is located at: S = (-4, -34)

Answer: (0, -34)

Step-by-step explanation:

[tex]M(5,-8)=(\frac{x_{1} + x_{2} }{2} ,\frac{y_{1} + y_{2} }{2})\\(5,-8)(\frac{10 + x_{2} }{2} ,\frac{18 + y_{2} }{2})[/tex]

[tex]5=(\frac{10 +x_{2} }{2})\\ 10=10+x_{2} \\-10-10\\0 = x_{2}\\x_{2} =0[/tex]    [tex]-8=(\frac{18 +y_{2} }{2})\\ -16=18+y_{2} \\-18-18\\-34 = y_{2}\\y_{2} =-34[/tex]

Coordinates of point S = (0, -34)

Answer:

Answer:

24% saline

Step-by-step explanation:

Find how much saline is in both solutions:

7(0.27)

= 1.89

3(0.17)

= 0.51

Add this together:

1.89 + 0.51

= 2.4

Since there are 10 quarts in total, the concentration of the mixture can be found by dividing 2.4 by 10:

2.4/10

= 0.24

So, the concentration of the mixture is 24% saline
