which of the following fractions is closest to 5/8. 2/3, 13/20 or 11/16​

Hey there! :)

Answer:

Third option. x = 2, and x = 4.

Step-by-step explanation:

Find the zeros of this quadratic equation by factoring:

f(x) = x² - 6x + 8

Becomes:

f(x) = (x - 4)(x - 2)

Set each factor equal to 0 to solve for the roots;

x - 4 = 0

x = 4

x - 2 = 0

x = 2

Therefore, the zeros of this equation are at x = 2, and x = 4.

Answer:

x=4  x=2

Step-by-step explanation:

f(x) = x^2 − 6x + 8

To find the zeros, set equal to zero

0  = x^2 − 6x + 8

Factor

What 2 numbers multiply to 8 and add to -6

-4*-2 = 8

-4+-2 = -6

0 = ( x-4) (x-2)

Using the zero product property

x-4 =0    x-2=0

x=4  x=2

Answer:

-3

Step-by-step explanation:

Substitute negative 3 as x and you get this -(--3). Then the two negatives make a positive and it's -(3) which becomes -3.

Answer:

He has ran 15 miles and passed the bank 12 miles from his location where he is at.

Step-by-step explanation:

WHY WAS HE ROBBING A BANK?????????

Answer:

Step-by-step explanation:

His distance from the bank can be modeled using an equation in the form y=mx+b. Since he has already ran 3 miles, the "b" is equal to 3, and can be added to how many miles he runs on from now on. If he can run 5 miles per hour, then that means every hour, he will run 5 miles. We can represent how many hours have passed as x. This would make our equation y=5x+3.

After 3 hours he has gone 5(3)+3 miles, or 18 miles

1. Zero to four roots.

2. No general symmetry.

3. 0ne,two or three extrema.

4. Roots are solved by radicals.

Answer:

The correct answer is - The setting may discourage honest responses.

Step-by-step explanation:

In this particular setting of research and interview regarding this research may not produce hones results as the question is too direct to ask students if they had ever used drugs.

Research should be anonymous and should avoid the questions that can lead to bias results like this case that may lead to dishonest results.

Thus, the correct answer is : The setting may discourage honest responses.

Complete the paragraph proof. Given: ∠ABR and ∠ACR are right angles AB ≅ BC BC ≅ AC Prove: bisects ∠BAC

It is given that ∠ABR and ∠ACR are right angles, AB ≅ BC and BC ≅ AC Since they contain right angles, △ABR and △ACR are right triangles. The right triangles share hypotenuse AR, and reflexive property justifies that AR ≅ AR. Since AB ≅ BC and BC ≅ AC, the transitive property justifies AB ≅ AC. Now, the hypotenuse and leg of right △ABR is congruent to the hypotenuse and the leg of right △ACR, so △ABR ≅ △ACR by the HL congruence postulate. Therefore, by CPCTC, and bisects ∠BAC by the definition of bisector.

Answer:

The answer is ∠BAR=∠CAR

Step-by-step explanation:

Answer:

B: x>4

Step-by-step explanation:

You want to make an inequality first:

36+4x>52

4x + 36 − 36 > 52−36

4x > 16

4x ÷ 4 > 16 ÷ 4

x > 4

Answer:

x=6

Step-by-step explanation:

4x-4=2x+8

Get all x's to one side. Subtract 2x from both sides.

2x-4=8

Isolate x. Add 4 to both sides.

2x=12

Divide both sides by 2 to get x.

12/2=6

x=6

Answer:

Adult ticket: $7

Child ticket: $2

Step-by-step explanation:

Set up a system of equations where a represents the cost of one adult ticket and c is the cost of one child ticket:

2a + 3c = 20

a + 4c = 15

Solve by elimination by multiplying the bottom equation by -2:

2a + 3c = 20

-2a -8c = -30

Add them together:

-5c = -10

c = 2

Now, we can plug in 2 as c to find the value of a:

2a + 3c = 20

2a + 3(2) = 20

2a + 6 = 20

2a = 14

a = 7

The solution is

The cost of one adult ticket = $ 7

The cost of one child ticket = $ 2

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the cost of one adult ticket be = x

Let the cost of one child ticket be = y

Now , for Family 1 :

2 adults and 3 children and costs a total of £20 to enter the park

Substituting the values in the equation , we get

2x + 3y = 20   be equation (1)

Now , for Family 2 :

1 adult and 4 children and costs a total of £15 to enter the park

Substituting the values in the equation , we get

x + 4y = 15   be equation (2)

On simplifying the equations , we get

Multiply equation (2) by 2 , we get

2x + 8y = 30   be equation (3)

Subtracting equation (1) from equation (3) , we get

5y = 30 - 20

5y = 10

Divide by 5 on both sides of the equation , we get

y = 2

So , the cost of one child ticket is $ 2

Now , substituting the value of y in equation (2) , we get

x + 4y = 15

x + 4 ( 2 ) = 15

x + 8 = 15

Subtracting 8 on both sides of the equation , we get

x = 15 - 8

x = 7

So , the cost of one adult ticket is $ 7

Hence , the value of x is $ 7 and value of y is $ 2

Answer:

Advance tickets=$25

Same-day tickets=$15

Step-by-step explanation:

Complete question below:

Suppose that there are two types of tickets to a show: advance and same-day. The combined cost of one advance ticket and one same-day ticket is $ 40. For one performance, 25 advance tickets and 30 same-day tickets were sold. The total amount paid for the tickets was $1075 . What was the price of each kind of ticket?

Let

advance tickets=x

Same-day tickets=y

Combined cost of advance and same-day tickets=$40

It means,

x+y=40 Equ (1)

25 advance tickets and 30 same-day tickets=$1075

It means,

25x+30y=1075 Equ(2)

From (1)

x+y=40

x=40-y

Substitute x=40-y into (2)

25x+30y=1075

25(40-y)+30y=1075

1000-25y+30y=1075

5y=1075-1000

5y=75

Divide both sides by 5

5y/5=75/5

y=15

Recall,

x+y=40

x+15=40

x=40-15

=25

x=25

Advance tickets=$25

Same-day tickets=$15

Check

25x+30y=1075

25(25)+30(15)=1075

625+450=1075

1075=1075

Answer:

Step-by-step explanation:

- 8x + 44 ≥ 60

Subtract 44 from both sides

- 8x + 44 - 44 ≥ 60 - 44

- 8x ≥ 16

Divide both sides by -8 and flip the inequality sign

-8x/-8 ≤ 16/-8

x ≤ -2

x = {   ......... -4,-3,-2}

2) -4x + 50  < 58

Subtract 50from both sides

-4x + 50 -50 < 58- 50

-4x < 8

Divide both sides by -4 and flip the inequality sign

-4x/-4 > 8/-4

x > -2

x= {-1, 0 , 1 , 2....... }

Answer:

Step-by-step explanation:

1. [tex] - 8x + 44 \geqslant 60[/tex]

Move constant to R.H.S and change its sign

[tex] - 8x \geqslant 66 - 44[/tex]

Subtract the numbers

[tex] - 8x \geqslant 16[/tex]

Divide both sides of the inequality by -8 and flip the inequality sign

[tex]x \leqslant - 2[/tex]

2. [tex] - 4x + 50 < 58[/tex]

Move constant to the R.H.S and change its sign

[tex] - 4x < 58 - 50[/tex]

Subtract the numbers

[tex] - 4x < 8[/tex]

Divide both sides of the inequality by - 4 and flip the inequality sign

Answer:

75

it has to be smaller then 87 and bigger then 53

Answer:

Step-by-step explanation:

Given the expression  (sec θ + tan θ) x (1 – sin θ), to simplify he expression the following steps must be followed. First we must know that from trigonometry identity, secθ = 1/cos θ and tanθ = sinθ/cosθ

Substituting this foremulas in the expression we will have:

(sec θ + tan θ) x (1 – sin θ)

= (1/cosθ + sinθ/cosθ)* (1-sinθ)

= (1+sinθ/cosθ) *1-sinθ

= {(1+sinθ)(1-sinθ)/cosθ}

= (1-sinθ+sinθ-sin²θ)/cosθ

= 1-sin²θ/cosθ

Also, from pythagoras therorem, sin²θ+cos²θ = 1

cos²θ = 1-sin²θ

substituting cos²θ = 1-sin²θ into the final expression above we have:

1-sin²θ/cosθ = cos²θ/cosθ

= cosθ

(sec θ + tan θ) x (1 – sin θ) = cosθ

Sonya left her house and accelerated as she drove toward the highway entrance. She increased her speed as she drove up the ramp to the highway and then drove a constant speed on the highway.

Step by step explanation:

The first scenario is the best match for the increasing slope, (leaving the house and accelerating) rapidly increasing slope (increasing speed on ramp) and level line (constant speed on the highway).

The best interpretation of the graph is,

Sonya left her house and accelerated as she drove toward the highway entrance. She increased her speed as she drove up the ramp to the highway and then drove a constant speed on the highway.

When a point or an object moving in a straight line , the acceleration is the rate at which velocity changes with time, in terms of both speed and direction.

Here, we have,
