Answer:

1/2

Step-by-step explanation:

y/-5=1/10

multiply -5 on both sides

y/-5 x -5 - cancels

1/10 x -5/1

1/10 x -50/10 = 5/10 = 1/2

so then its y=1/2

16. Find the values of x and y. (2y + 5) (5x - 17) (3x – 11)º

Answers

Answer:

x = 26

y = 9

Step-by-step explanation:

(5x - 17)° + (3x - 11)° = 180° (angles in a straight line)

Solve for x

5x - 17 + 3x - 11 = 180

Collect like terms

5x + 3x - 17 - 11 = 180

8x - 28 = 180

Add 28 to both sides

8x = 180 + 28

8x = 208

Divide both sides by 8

x = 208/8

x = 26

Also:

(2y + 5)° + 90° + (3x - 11)° = 180° (angles on a straight line)

Plug in the value of x and solve for y

2y + 5 + 90 + 3(26) - 11 = 180

2y + 5 + 90 + 78 - 11 = 180

Collect like terms

2y + 162 = 180

Subtract 162 from both sides

2y = 180 - 162

2y = 18

y = 9 (dividing both sides by 2)

the sum of 3 numbers is 114. the second number is 4 times the third the third number is 6 more than the first

Answers

Answer:

let the three numbers be x,y,z

X= z-6

Y= 4z

Z= z

Step-by-step explanation:

X+Y+Z=114

hence

=z-6+4z+z=114

=collect like times. X= 20-6=14

= z+4z+z=114+6. Y= 20*4=80

=6z=120. . Z= 20

z=20

Answer:

  14 + 20 + 80 = 114

Step-by-step explanation:

Let's begin by representing our 1st number as x.

Then our 2nd number is said to be 6 more than the 1st number, which we can represent as x + 6.

Lastly, our 3rd number is said to be 4 times the 2nd number, which we can represent as 4(x + 6).

Now can write our equation to express the sum of these three numbers as 114 and then solve for x to find the values of these three numbers:

   x + (x + 6) + 4(x + 6) = 114

   x + x + 6 + 4x + 24 = 114

   6x + 30 = 114

   6x = 114 - 30

   6x = 84

     x = 84/6 = 14 (1st number)

     x + 6 = 14 + 6 = 20 (2nd number)

     4(x + 6) = 4(20) = 80 (3rd number)

We can check our answers by adding these numbers up to see if their sum is 114:

    14 + 20 + 80 = 114

    34 + 80 = 114

    114 = 114

Their sum is 114, so we are confident that our three numbers are correct.

Use the map shown below to find the distance between cities A and B to the nearest tenth.

Answers

Answer:

7.2 units

Step-by-step explanation:

Coordinates of city A = (0, 0)

Coordinates of city B = (6, 4)

Use the distance formula to find the distance between the two cities as follows:

[tex] AB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

Let,

[tex] A(0, 0) = (x_1, y_1) [/tex]

[tex] B(6, 4) = (x_2, y_2) [/tex]

Plug in the values into the formula

[tex] AB = \sqrt{(6 - 0)^2 + (4 - 0)^2} [/tex]

[tex] AB = \sqrt{(6)^2 + (4)^2} [/tex]

[tex] AB = \sqrt{36 + 16} = \sqrt{52} [/tex]

[tex] AB = 7.2 [/tex] (nearest tenth)

Area of the circle: 64π ft²

Radius of circle: 8 ft

The circumference formula: C = d · π

We can plug in the values we know.

d = 16ft; r = 8ft

The maximum speed that an X43A plane can reach is 7,500 miles per hour. At this speed, how many feet
can the X43A travel in 1 second? (1 mile = 5,280 feet)

Answers

Answer:

11000 feet/seconds

Step-by-step explanation:

This problem requires that we convert from miles per hour to feet per seconds

Given that the speed of the X43A plane is 7500 mph

and that 1 mile = 5,280 feet)

[tex]=\frac{7500miles}{h} *\frac{5280 feet}{mile} \frac{1hour}{3600 seconds} \\\\=\frac{7500*5280}{3600} \\\\=\frac{396*10^5}{3600} \\\\=11000 feet/seconds\\\\=11*10^3feet/seconds\\\\[/tex]

Therefore the speed of the X43A plane in feet per second is 11000
