Step-by-step explanation:

Answer:

0.57, which is a number between 0 and 1

Step-by-step explanation:

The fraction 4/7 is approximately equal to 0.57 as a decimal, so you would plot 4/7 where 0.57 should go

Answer:

Between 0 and 1

Step-by-step explanation:

Answer:

0.4285714286.

The hundredth place is 2 places to the right of the decimal. In this case, it is 2. So we look to the number to the right of 2 (which is 8). 8 ≥ 5, so the 2 gets rounded to a 3.

0.43

Answer:

The answer is 0.43

Step-by-step explanation:

When you divide 3 by 7, you get 0.42857142857142857142857142857143.

To round to the nearest hundredth, you go 2 numbers after the decimal place. The number on the right of the 2nd number (which is in the hundredths place) will either make the number round up or down. Since the number 8 is greater than 5, the number rounds up.

So, the answer will be 0.43

Answer:

Y(0, - 14 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ [tex]\frac{1}{2}[/tex] (x₁ + x₂ ), [tex]\frac{1}{2}[/tex] (y₁ + y₂ ) ]

Use the midpoint formula and equate corresponding parts to the coordinates of the given midpoint

let Y = (x, y ), then

[tex]\frac{1}{2}[/tex] (4 + x) = 2 ( multiply both sides by 2 )

4 + x = 4 ( subtract 4 from both sides )

x = 0

and

[tex]\frac{1}{2}[/tex] (4 + y ) = - 5 ( multiply both sides by 2 )

4 + y = - 10 ( subtract 4 from both sides )

y = - 14

Thus

coordinates of Y = (0, - 14 )

Answer:

x=-8

Step-by-step explanation:

-3(3x+8)+2=26-3x

We move all terms to the left:

-3(3x+8)+2-(26-3x)=0

We add all the numbers together, and all the variables

-3(3x+8)-(-3x+26)+2=0

We multiply parentheses

-9x-(-3x+26)-24+2=0

We get rid of parentheses

-9x+3x-26-24+2=0

We add all the numbers together, and all the variables

-6x-48=0

We move all terms containing x to the left, all other terms to the right

-6x=48

x=48/-6

x=-8

Answer:

It would be -28, -29, and -30.

Step-by-step explanation: It would be these answers since the numbers are negative the "less than" would be in the other direction.

For n = 4, all of the given expressions are equivalent except 16 and

(n - 2).

What is Substitution method?

To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.

The expressions are;

1. 16

2. n - 2

3. 1/16

4. 1/n²

Now, Put n = 4 in all given expression we get;

The first expression is,

16

The second expression is,

n - 2

= 4 - 2

= 2

The third expression is,

1/16

The fourth expression is,

1/n²

= 1/4²

= 1/16

Hence, Third and fourth expression are same.

So, For n = 4, all of the given expressions are equivalent except 16 and

Complete Question

A field in the shape of a trapezoid has an area of 13,687.5 square yards the length of one base is 150 yards and the length of the other base is 215 yards what is the height of the trapezoid

Answer:

The height of the trapezoid is 75 yards

Step-by-step explanation:

Area of a Trapezoid = 1/2(b1 + b2) × h

Where b1 = Length of the first base

b2 = Length of the second base

h = height of the trapezoid

From the question

Area of the trapezoid = 13,687.5 yd²

b1 = Length of the first base = 150 yards

b2 = Length of the second base = 215 yards

h = height of the trapezoid

Hence, we have

13,687.5 = 1/2(150 + 215)h

13,687.5 = 365h/2

13,687.5 × 2 = 365h

h = 13687.5 × 2/365

h = 75 yards

Therefore, the height of the trapezoid is 75 yards.

Answer: 5

Step-by-step explanation:

Since we know that equal number of dashes will always be equal to another we can easily solve the question. They said AB=8 and as you can see 8 is represented by two dashes here and if we take in what i said earlier,, that means DC= 8 too. They also said AD= 5. Since 5 is represented by one dash we can easily see that since BC also has one dash,, it is going to be equal to AD which concluded to the answer of 5.

Answer:

[tex]\dfrac{3}{85}[/tex]

Step-by-step explanation:

It is given that a small town’s raffle has 85 entries and 3 gift baskets that three different people could win.

Total number of entries = 85

Total number of gift baskets = 3

We need to find the probability of winning a gift basket.

[tex]\text{Required probability}=\dfrac{\text{Total number of gift baskets}}{\text{Total number of entries}}[/tex]

[tex]\text{required probability}=\dfrac{3}{85}[/tex]

Therefore, the required probability is [tex]\dfrac{3}{85}[/tex].

Answer:

JK = 39

Step-by-step explanation:

HJ and JK are segments of line segment HK, so they must add up to the length of KH.

HJ + JK = HK

By substituting in the values of each line segment, we can solve for t.

(4t - 15) + (5t - 6) = 15

9t - 21 = 15

9t = 36

t = 9

Now that we have t, we can plug it in in order to find the value of JK.

JK = 5t - 6

5(9) - 6

45 - 6

39

JK = 39

Answer:

29.

Step-by-step explanation:

The given expression is

[tex]5+2[(48-40)\div 4+(2\times 5)][/tex]

BODMAS = Bracket, Of, Division, Multiplication, Addition, and Subtraction.

Using BODMAS, we get

[tex]5+2[(8)\div 4+(10)][/tex]         (Brackets)

[tex]5+2[2+10][/tex]                  (Division)

[tex]5+2[12][/tex]               (Brackets)

[tex]5+24[/tex]                 (Multiplication)

[tex]29[/tex]           (Addition)

Therefore, the value of given expression is 29.

For this case, we must clear variable "x" from the given equation, expressed in terms of "a".

We have:

3/a x-4=20

By clearing "x" we have:

Adding 4 to both sides of the equation:

3/a x = 20 + 4

Multiplying by a/3 on both sides of the equation:

x=24a/3

x=8a

So, x=8a

Answer:

x=8a

This system 3x – 1 = 3x + 1 has no solution.

In order to determine the solution for the given system of equations, we would apply the substitution method. Based on the information provided above, we have the following system of equations:

y = 3x - 1      .......equation 1.

y = 3x + 1         .......equation 2.

By using the substitution method to substitute equation 2 into equation 1, we have the following:

3x - 1 = 3x + 1

3x - 3x = 1 + 1

0 = 2 (False).

Answer:

7x+1

Step-by-step explanation:

When you look at the expression(3x+2+4x-1), you will notice that some have variables while some are just regular numbers.

First, focus on the variables. 3x and +4x. In the expression, you will have to add it so 3x+4x will be 7x. Now, keep 7x on the side and switch to the numbers.

Next, focus on the numbers. 2 and -1. All you have to do is combine them which will be 2-1 which also equals 1.

Finally, return 7x with 1 which will be 7x+1. The reason you add a + sign instead of a - sign is because you got positive 1, not negative 1.

Your answer is 7x+1.

Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

Answer:

p = 1.5

Step-by-step explanation:

— 7 + 4p = -8p + 11

Add 8p to each side

— 7 + 4p+8p = -8p+8p + 11

-7 +12p = 11

Add 7 to each side

-7+7 +12p = 17

12p = 18

Divide each side by 12

12p/12 =18/12

p = 18/12

p = 3/2
