What is the value of x? (There should be an image) ​

Answer:

d≈9.55

Step-by-step explanation:

the answer is 9.55 inches

Answer:

diameter = 9.55 in

Step-by-step explanation:

Circumference = pi x diameter     so re-arrange

circumference / pi = diameter

       30 / pi = diameter

   9.55 in = diameter

Answer: ∠PQR = 130°

Step-by-step explanation:

      The word bisects means that angle PQS and SQR are equal to each other.

           3x + 5 = 2x + 25

           3x = 20

           x = 20

      Now, we will plug this value back in and solve for angle PQR. There are three ways we could do this.

      [1]

             (3x + 5) + (2x + 25)

             (3(20) + 5) + (2(20) + 25)

             (60 + 5) + (40 + 25)

             (65) + (65)

                 130 degrees

      [2]

             (3x + 5) * 2

             (3(20) + 5) * 2

             (65) * 2

                 130 degrees

      [3]

             (2x + 25) * 2

             (2(20) + 25) * 2

             (65) * 2

                 130 degrees

Answer:

the answer is 0.

Step-by-step explanation:

When you are adding two of the same numbers together, and one of them is positive while the other is negative, they cancel each other out.

Answer:

a = 2

Step-by-step explanation:

given x = - 1 is a zero then f(- 1) = 0 , that is

a(- 1)³ - (- 1)² - 1 + 4 = 0

- a - 1 - 1 + 4 = 0

- a + 2 = 0 ( subtract 2 from both sides )

- a = - 2 ( multiply both sides by - 1 )

a = 2

Answer:

Answer:

x = 6, y = 5

Step-by-step explanation:

5x - 4y = 19 -------> equation 1

x + 2 = 8 --------> equation 2

Step 1 : Subtract 2 on both sides in equation 2.

x + 2 - 2 = 8 - 2

x = 6

Step 2 : Substitute the value of x is equation 1.

5 ( 6 ) - 4y = 19

( 5 * 6 ) - 4y = 19

30 - 4y = 10

Step 3 : Subtract 30 on both sides.

30 - 30 - 4y = 10 - 30

- 4y = - 20

Step 4 : Multiply - 1 on both sides.

- 1 * - 4y = - 1 * - 20

4y = 20

Step 5 : Divide 4 on both sides.

4y / 4 = 20 / 4

y = 5

Hence,

x = 6

y = 5

Answer:

x = 5, y = 3/2.

Step-by-step explanation:

5x-4y=19

x+2y =8               Multiply this by 2:

2x + 4y = 16       Adding this to first equation 1:

7x = 35

x = 5

So

5 + 2y = 8

2y = 3

y = 3/2.

Answer:

-1

Step-by-step explanation:

The options w > x, w > y, and x + y = w are correct because the sum of the two interior angles is equal to the exterior angle.

When two lines or rays converge at the same point, the measurement between them is called a "Angle."

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

From the figure,

The interior angle of a triangle is w

w > x (true)

w > y (true)

x + y = w (sum of the two interior angles is equal to the exterior angle)

Thus, the options w > x, w > y, and x + y = w are correct because the sum of the two interior angles is equal to the exterior angle.

The speed of Sali is 18.75 km/hr.

Given,

Total distance travelled by Jane and Sali =63 km.

The total time is taken by Jane=3.5 hours.

Sali started to cycle 4 minutes after Jane started to cycle [tex]=\frac{4}{60}=\frac{1}{15}[/tex] hours.

The formula to find speed is [tex]Speed=\frac{Distance}{Time} \ km/hr[/tex].

The speed of Jane[tex]=\frac{63}{3.5}=18 \ km/hr[/tex].

Let the speed of Sali be [tex]x \ km/hr[/tex].

Sali caught up with Jane when they had both cycled 30 km.

Thus, [tex]\frac{30}{18}-\frac{30}{x}=\frac{1}{15}[/tex]

[tex]\implies \ \frac{30x-540}{18x} =\frac{1}{15}[/tex]

[tex]\implies \ 15(30x-540)=18x[/tex]

[tex]\implies \ 5(30x-540)=6x[/tex]

[tex]\implies \ 150x-2700=6x[/tex]

[tex]\implies \ 144x=2700\implies \ x=18.75[/tex]

1386m cubic

Step-by-step explanation:

hope it helps.in case of any other question, you can count on me.good day.

The area of the circular field in square meters will be equal to, 1386 m².

An object's area is how much space it takes up in two dimensions. It is the measurement of the number of unit squares that completely encompass a compact figure's surface. The squared unit, which is frequently expressed as inches, square feet, etc., is the accepted unit of area.

As per the given information in the question,

Total number of posts = 66

Distance between two posts = 2 meters

Then, the circumference of the area will be,

= 66 × 2 = 132 meters

Now, let's find the radius of the circle,

C = 2πr

132 = 2 × 3.14 × r

r = 132/(2 × 3.14)

r = 21.01 m

Use the formula for the area of the circle:

A = πr²

A = 3.14 × (21.01)²

A = 441.420 × 3.14

A = 1386 m²

The probability that a person wins the game is 32.1%

Based on the information given, the following can be depicted. It should be noted that there are 6 sides as well as 4 cards.

Therefore, the numbers on the dice i.e from 1 - 6 will be represented 4 times each. This gives a total of (4 × 6) = 24. There are also 4 cards. The total in sample space will now be:

= 24 + 4 = 28

The frequency table will be such that 28 or more has a relative frequency of 9. Therefore, the probability that a person wins the game will be:

= 9/28 = 32.1%

When you win 25% of the time, this illustrates that the number of products picked will be:

Answer: 80 miles

Step-by-step explanation:

- 400/5 = 80

- so 80 is 1/5 of 400

hope this helps :)

Answer:

80 miles

Step-by-step explanation:

The whole journey is 400 miles, so we say that he traveled x miles, where x equals 400.
if we multiple 1/5 by x miles, then we will get how much he travels
1/5*x = 1/5*(400), since x = 400, so you can replace x with 400
1/5*x=1/5*400=400/5=80 miles

Answer:

mean: 2.6, mode: 1, median: 1

Step-by-step explanation:

The mean is essentially the average of the data set which can be defined as: [tex]\frac{\text{sum of data set}}{\text{amount of data in data set}}[/tex]. So adding all the values together you get: [tex]26[/tex]. and counting all the numbers in the data set you find the data set has 10 numbers. This gives you the equation: [tex]\frac{26}{10} = 2.6[/tex] which is the mean

To find the mode, you find which number occurs most frequently, this is of course 1, which can really be determined by just looking at the data set for a second. all the other numbers only occur once, while 1 is in the data set 5 times. So 5 is the mode

To find the median you sort the data, from min to max, and then find the middle number. Sorting the data set gives you. -2, 1, 1, 1, 1, 1, 4, 5, 6, 8. Since this data set has an even amount of numbers, there is not going to be an exact middle. If you go the "middle" which is the 5th and 6th number, you add these two numbers and divide the sum by 2. This gives you: (1+1)/2 = 1 So the median is 1
