Answer:

x = 13; y = 13; z = 18

Step-by-step explanation:

In a rhombus, opposite angles are congruent and consecutive angles are supplementary.

6x + 8 = 86

6x = 78

x = 13

7y + 3 + 86 = 180

7y + 89 = 180

7y = 91

y = 13

5z + 4 + 86 = 180

5z + 90 = 180

5z = 90

z = 18

Answer:

x=13

y=13

z=18

Answer:

1 person = 0.75

1 person = 3/4

Step-by-step explanation:

This answer is at best a guess. It seems to me that you are constructing a circle graph, and I would like that confirmed.

The total number of people in the survey is

Total in survey = 96 + 60 + 24 + 96 + 204

Total in survey = 480

A circle contains 360 degrees.

480 people have 360 degrees of circle room

1  person has x degrees of circle room

480 / 1 = 360 / x

Cross multiply

480 x = 360 *1       Divide both sides by 480

x = 360 / 480

x = 0.75

One person takes 3/4 of a degree of the circle.

So the number of people wanting to go to the UK would be

96 * 0.75 = 72 degrees,

For each part of the table, just use what the frequency is for that entry where 96 is now.

Answer:   y = 2x - 5

Step-by-step explanation:

slope- intercept form is always written as y = mx + b, where m = slope, and b is the y-intercept.

To find b, substitute the point and the slope into the equations, you will get:

y = mx + b

9 = 2(7) + b

9 = 14 + b

-5 = b

Plug in m and b into the equation, we get:

y = mx + b

y = 2x + (-5)

y = 2x - 5

Answer:

We are given the table of a linear function

Since we have to find the equation of the function in the slope-intercept form,

we require the slope as well as the y-intercept

Finding the slope:

We know that slope of a line is Rise / Run

Since from the graph, we notice that the difference of 2 consecutive x-coordinates is 1

Hence, we have the x-coordinates at an interval of 1 and since the slope of a line is defined as the units ascended by the line after covering 1 unit in the x-coordinate

change in y = y[tex]_{n}[/tex] - y[tex]_{n-1}[/tex]       (where n is the number of row in the table)

change in y = 31 - 23

change in y = 8 = Rise

Run = 1 (Since the interval in the table is 1)

Slope = Rise / Run

Slope = 8 / 1

Slope  = 8

Finding the y-intercept:

We need the y-coordinate at x = 0

Going up from the third row, we notice that for every unit decreased in the x-coordinate , 8 units of the y-coordinate are decreased (since the slope =8)

In that case, the y-coordinate of every decreased x-coordinate will be 8 less than the last one

so we can say that the y-coordinate of x = 1 will be 8 less than 23 since x=1 is one less than x = 2

similarly, we can also say that the y-coordinate of x = 0 will be 8 less than (23-8) since x = 0 is one less than x = 1

Therefore, the y-coordinate at x =0

y = (23-8-8)

y-intercept  = 7

Making the Equation:

We need to write the equation in the form:

y = ax + b (where a is the slope of the line and b is the y-intercept)

Replacing the known values, we get

y = 8x + 7

Therefore, the equation of the formula shown in the table is y = 8x + 7

The number of hits of the baseball player when batting is the average of hit

The expected number of hits in a bat of 4 is 1

The given parameters are:

The battling average, p = 0.250

The number of bats, n = 4

The number of hits in the bat is the average of hit, and it is calculated as:

[tex]E(x) = np[/tex]

This gives

[tex]E(x) = 4 * 0.250[/tex]

Evaluate the product

[tex]E(x) = 1[/tex]

The solution when multiplied 6 times 3 and then dividing by 2 is 9.

Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.

a × b means that a is added to itself b times or b is added to itself a times.

Given that,

Multiply six times three then divide by two.

First we have to multiply 6 times 3.

6 × 3 = 18

Then we divide the answer by 2.

18 ÷ 2 = 9

Hence the solution is 9.

Start with the formula for finding the area of a circle.

A=πr2

First, substitute the given information in the equation. You have the area and you know that pi is 3.14.

153.86=(3.14)r2

Next, divide the area by pi. This will help to get one step closer to figuring out the radius.

3.14)153.86¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯

Remember, when you divide decimals, to move the decimal two places in the divisor and the dividend.

314)15386¯¯¯¯¯¯¯¯¯¯¯¯¯¯

314)15386¯¯¯¯¯¯¯¯¯¯¯¯¯¯  49− 1256  ––––––––  2826  − 2826–––––––0

So far, the answer is 49, but that is not the radius because r2 is on the right side of the equal sign.

49=r2

Then, you need to figure out which number times itself is equal to 49. You can figure this out by finding the factors of 49.

7×7=49

Now, you know that the radius is 7 inches because 7×7=49.

The radius is 7 inches.

Finally, to figure out the diameter, which is twice the radius, multiply the radius by 2.

7×2=14

The diameter is 14 inches.

The radius covered by the tower will be 20 miles.

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called the area of the circle.

Given that a cell phone tower services about 1,256sq. miles. The area of the circle will be calculated by the formula,

Area = πr²

1256 = π x r²

r² = ( 1256 / π )

r² = 400

r = √400

r = 20 miles

Hence, the radius of the circle will be 20 miles.

There's a repetitive pattern of adding +10 each time.

Answer:

Step-by-step explanation:

answer: the original number is 62.

Given :

Units digits is thrice the tens digit

The digits interchange when - 36 is added

To find :

The number

Solution :

✯

Let the digits be -

   Units place as 3y

   Tens place as 10(y)

⇒ 10(y) + 3y

⇒ 10y + 3y

⇒ 13y --------- (Orignal Number)

✯

Let the digits be -

   Units place as y

   Tens place as 10(3y)

⇒ 10(3y) + y

⇒ 30y + y

⇒ 31y --------- (Number with reversed digits)

✯

The number gets reversed when 36 is added to it.

⇒ 13y + 36 = 31y

⇒ 13y - 31y = - 36

⇒ 18y = 36

⇒ y = 36/18

⇒ y = 2

✯

⇒ 13y

⇒ 13(2)

⇒ 26

✯

The units place should be thrice of the tens place,

⇒ 2 × 3 = 6

Units place is 6

Reversed digits are 62,

⇒ 26 + 36 = 62

⇒ 62 = 62

The Orignal Number is 62.

Answer: both ways are acceptable

Step-by-step explanation: When writing equations of lines in this form,

we usually keep the "b" value or the constant term as a fraction.

However, if you prefer decimals, you can absolutely change

it to a decimal to visualize is better if you'd like, it's really your choice.

For example, if the equation of a line was y = -3/4x - 7/4, I could leave

it how it is or I could change the -7/4 to -1.75 giving me y = -3/4x - 1.75.

Answer:

Y= -5/2x +16

Step-by-step explanation:

To solve this, understand that (-8,4) is (x,y)

And Slope intercept form is y=mx +b

Since you have a possible x and y with - 8 and 4, sub that in making it 4=m(-8) + b

We also have the Slope (or M) which is -5/2, sub that in and get 4 = -5/2 (-8) + b

Do the multiplication and get 4= 40/2 +b

Simplify to 4= 20 + b

Then re-arrange to have the unknown (b) on one side and known on the other (when you move a number over the equal sign its sign, positive or negative, becomes the opposite)

B= 20-4

Subtract

B= 16

Now you know the b and can add it to your equation,

Y= -5/2x +16

Answer:

y = -5/2x - 16.

Step-by-step explanation:

First use the point-slope form of a line:

y - y1 = m(x - x1)

y - 4 = -5/2(x - (-8))

y - 4 = -5/2x - 40/2

y =  -5/2x - 20 + 4

y = -5/2x - 16.
