Step-by-step explanation:

Answer: 200

Step-by-step explanation: You can use the Pythagorean theorem for this question. First, you must find a and b. You can do this by finding the distance between North and South, and East and West. For this specific equation, you'd use 200 North - 30 North to get 170 miles on the y-axis. Then, you'd do 50 East + 100 West to get 150 kilometers distance on the x-axis. Now that you have 170 and 150, you can begin the equation

170^2 + 150^2 = c^2

28900 + 22500 = c^2

51400 = c^2

√51400 = √c^2

~226 = c

They are approximately 226 kilometers apart, and 226 is closest to 200, which is B.

Answer:

Answer= 50%

Step-by-step explanation:

7k=7000g

7000÷350=20

20x75p=1500p

1500=£15

£15 is £5 more than £10. £5 is half of £10 meaning its an extra 50%

Answer:

x = 111º

Step-by-step explanation:

In a heptagon, (A polygon with 7 sides, and therefore 7 angles), the sum of the interior angles is always 900º (just like the sum of all interior angle in a quadrilateral is always 360º). So you can add up all of the interior angles, and subtract them from 900º.

900º - (158º + 120º + 126º + 125º + 121º + 139º) = 111º

Answer:

The slope is -2.

Step-by-step explanation:

1) The equation for a slope is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].

2) Plug in x and y values into the equation. I plugged in (3,0) and (8,-10) into the equation.

3) You end up with: [tex]\frac{-10 -0}{8-3}[/tex], which simplifies down to [tex]\frac{-10}{5}[/tex], which equals -2.

Answer:

the slope is -2.

Step-by-step explanation:

plot the points on a graph, then draw a line through them. count the rise/run, which equals the slope.

Answer:

Hey there,

The answer is below!!

Step-by-step explanation:

Knowing that those vectors start at the point (0,0) we can "think" them as lines.

As you may know, two lines are parallel if the slope is the same, then we can find the "slope" of the vectors and see if it is the same.

A) the vectors are: (√3, 1) and (-√3, -1)

You may remember that the way to find the slope of a line that passes through the points (x1, y1) and (x2, y2) is s = (y2 - y1)/(x2 - x1)

Because we know that our vectors also pass through the point (0,0)

then the slopes are:

(√3, 1) -----> s = (1/√3)

(-√3, -1)----> s = (-1/-√3) =  (1/√3)

The slope is the same, so the vectors are parallel.

Part B:

The vectors are: (2, 3) and (-3, -2)

the slopes are:

(2, 3) -----> s = 3/2

(-3, -2)----> s = -2/-3 = 2/3

the slopes are different, so the vectors are not parallel.

Answer:

3.712 x 10^8

Step-by-step explanation:

use the commutative property to reorder the terms

(5.8x 6.4) x (10^5 x 10^2)

multiply 5.8 x 6.4 = 37.12

add 5+2=8

37.12 x 10^7

write the number in scientific notation

3.712 x 10^8

that'sur answer

Answer: 5.8 x 10^5 =

              6.4 x 10^2 =

Step-by-step explanation:

There is 5   10's because number of exponents are 5

so you multiply 5.8 by 10 10 10 10 10

The other is 6.4

multiply that by 10 10

But you can't multiply by all of that with one constant

So you answer the first one 10 x 10 x 10 x 10 x 10 = 100000

the other is 100

So now you multiply 5.8 by 100000

And multiply 6.4 by 100

Answer:

Equation : y = 4.50D + 40

Number of pairs = 16

Step-by-step explanation:

It is given that:

Per day wage of Roger = $40

Commission on per pair of shoes = $4.50

Daily goal = $112

Number of pairs of shoes = D

Total earning = y

y = 4.50D + 40

112 = 4.50D + 40

4.50D = 112 - 40

4.50D = 72

Dividing both sides by 4.50

[tex]\frac{4.50D}{4.50}=\frac{72}{4.50}\\D = 16 \\[/tex]

Therefore,

Equation : y = 4.50D + 40

Number of pairs = 16
