Answer:    20/ 60 = 1/3

Step-by-step explanation:

60 beads in total which makes that the denominator and how many red beads in the numerator (20) then just reduce the fraction

Answer: C

Step-by-step explanation:

The triangle in the picture is an equilateral triangle. We know this is true because all sides are equal, as denoted by the tick marks. In equilateral triangles, each angle is 60° because when you add all the angles, you get 180°.

4x+8=60        [subtract both sides by 8]

4x=52            [divide both sides by 4]

x=13

Now, we know that C is the correct answer.

Answer: 0.985

Step-by-step explanation: The answer shown is accurate.

Answer:

1-0.985

Step-by-step explanation:

0.985+0.015=1. How I figured it out is 1-x=0.015, it must be 0.985. Hope it helps!

Given :

Nathan smiled at 50 people one day and recorded that 36 people smiled back at him.

To Find :

How many people should Nathan expect to return a smile if he smiles at 650 people over a period of time.

Solution :

Ratio of people smiled by total number of people is :

[tex]R = \dfrac{36}{50}[/tex]

Now, it is given that we have to use the given conditions.

Therefore, ratio will be same :

[tex]\dfrac{s}{650}=\dfrac{36}{50}\\\\s = \dfrac{36}{50}\times 650\\\\s = 468[/tex]

Therefore, number of smiles Nathan expect to return is 468.

[tex]AB =10.8166538264[/tex]

[tex]AB \approx10.8[/tex]

Step-by-step explanation:

[tex]A( - 5,6),B(1, - 3)[/tex]

[tex]A( - 5,6),B(1, - 3) \\ A( { x }_{ 1 } , { y }_{ 1 } ),B( { x }_{ 2 } , { y }_{ 2 } )[/tex]

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

[tex]AB = \sqrt{ {(1 - - 5)}^{2} + {( - 3 - 6)}^{2} } [/tex]

[tex]AB = \sqrt{ {(1 + 5)}^{2} + { (- 3 - 6)}^{2} } [/tex]

[tex]AB = \sqrt{ {(6)}^{2}+ {( - 9)}^{2} } [/tex]

[tex]AB = \sqrt{36 + 81} [/tex]

[tex]AB = \sqrt{117} [/tex]

[tex]AB =10.8166538264[/tex]

[tex]AB \approx10.8[/tex]

Answer:

x = -5 + [tex]\sqrt{26}[/tex]

Step-by-step explanation:

f(x) = x² + 10x - 1

        x² + 10x = 1

        x² + 10x + 25 = 1 + 25

        (x + 5)² = 26

take the square root of each side to get:

        x + 5 = √26

        x = √26 - 5  or -5 + √26

Step-by-step explanation:

8x6+(8)/2

48+4

42

Answer:

52

Step-by-step explanation:

So in order to answer this question we are going to have to use the order of operations by starting with the parenthesis of subtracting 4 from 12:

8 × 6 + (12 - 4) ÷ 2​

12 - 4 = 8

Now the equation looks like this:

8 × 6 + 8 ÷ 2

Now we multiply 8 by 6 and dividing 8 by 2 because multiplication and division come first​:

8 * 6 = 48

8/2 = 4

So the equation looks like this:

48 + 4

We now add them together to get our answer:

48 + 4 = 52

So the answer to this equation is 8 × 6 + (12 - 4) ÷ 2​ = 52

Hope this helps you

Answer:

f(x) = [tex]\frac{1}{4}x^{2}[/tex]  > f(x) = -0.5x² > f(x) = x²

Step-by-step explanation:

In a quadratic function leading coefficient decides the width of a graph.

In simpler words, leading coefficient decides the vertical stretch of the graph.

Higher the value of leading coefficient, higher the vertical stretch.

When a graph is vertically stretched it becomes narrower.

(Note: Minus sign of the coefficient decides the opening of the graph, upwards or downwards)

Therefore, f(x) = x² having coefficient = 1 is the narrowest and f(x) = [tex]\frac{1}{4}x^{2}[/tex] will be the widest.

So the descending order will be,

f(x) = [tex]\frac{1}{4}x^{2}[/tex]  > f(x) = -0.5x² > f(x) = x²

Answer:

The age of the youngest child = x = 6 years

The age of middle child = y = 8 years

The age of the oldest child = z = 12 years

Step-by-step explanation:

Let us represent:

The age of the youngest child = x

The age of middle child = y

The age of the oldest child = z

The sum of the ages of the children is 26.

Hence: x + y + z = 26...... Equation 1

The oldest is 4 years older than the middle

z = 4 + y

The youngest child is 2 years younger than the middle child

x = y - 2

Hence, we substitute 4 + y for z and y - 2 for x in Equation 1

x + y + z = 26...... Equation 1

y - 2 + y + 4 + y = 26

y + y + y -2 +4 = 26

3y + 2 = 26

Subtract 2 from both sides

3y + 2 - 2 = 26 - 2

3y = 26 - 2

3y = 24

y = 24/3

y = 8

Solving for x

x = y - 2

x = 8 - 2

x = 6

Solving for z

z = 4 + y

z = 4 + 8

z = 12

Therefore:

The age of the youngest child = x = 6 years

The age of middle child = y = 8 years

The age of the oldest child = z = 12 years

Answer:

f(x)

Step-by-step explanation:

f(x)=x-1/x+5

y=x-1/x+5

xy+5y=x-1

xy-x=-1-5y

x(y-1)=1-5y

x=-1-5y/y-1

x=-5

Answer:

y = -3x -16

Step-by-step explanation:

For problems like this, I like to start with a variation of the point-slope form of the equation of a line:

y = m(x -h) +k . . . . . for a line with slope m through point (h, k)

For your given values, this is ...

y = -3(x +3) -7

y = -3x -9 -7 . . . . eliminate parentheses; next, combine terms

y = -3x -16

Answer:

6 nickels and 4 dimes

Step-by-step explanation:

6 times .05 is .30

4 times .10 is .40

just add them

.40 + .30 = .70

The equation should be:

.70 = .10y + .05x

I have 4 dimes and 6 nickels.

The question is ill-formatted. The following is the question.

You have a total of ten coins in your pocket, all of which are nickels and dimes. The total value of the coins is $0.70. To find nickels and dimes in your pocket, write and solve a system of linear equations. Let x represents the number of nickels and let y represent the number of dimes. Find the number of nickels and dimes.

One-hundredth of a dollar is equivalent to one cent.

A nickel is worth 5 cents. That means $0.05.

A dime is worth 10 cents. That means $0.10.

As per the question,

conversion of the statements into mathematical equations:

Subtracting the above equation from the below equation we get y=4.
And by substituting y=4 in x+y=10 we get x=6.

Hence, I have 4 dimes and 6 nickels.
