Answer:

100 degrees

Step-by-step explanation:

angle x and y are 100 degrees

angle x and y are the same because of the angle marks the question gives

next if we think of this mathematically, we know that all the angle degrees must = 360 so,

360=60+2x+x

Stephen had 24 miniature cars. he gave 4 cars to his brother.then he divided 4 equally among his friends .write an expression to

Svetlanka [38]

Total number of cars with Stephen = 24

Stephen gave 4 cars to his brother,

24-4 = 20 cars are left with Stephen.

Then, Stephen divided 4 equally among his friends.

That means Stephen divided 4 cars among the friends.

So, $\frac{24-4}{5} = 4$

So, Stephen divided 4 miniature cars among 5 friends.

The expression $\frac{24-4}{5} = 4$ denotes the words given in the above context.

(1)Arrange the list of numbers in increasing order.

yuradex [85]

Hello,

I)
$\dfrac{2}{5}=\dfrac{2*9*7}{5*9*7}=\dfrac{126}{315}$

$\dfrac{4}{9}=\dfrac{4*5*7}{315}=\dfrac{140}{315}$

$\dfrac{3}{7}=\dfrac{3*5*9}{315}=\dfrac{135}{315}$

or
$\dfrac{126}{315}\leq\dfrac{135}{315}\leq\dfrac{140}{315}$
thus
$\dfrac{2}{5}\leq\dfrac{3}{7}\leq\dfrac{4}{9}$

II)

$\dfrac{\dfrac{1}{2}+\dfrac{5}{6}}{2}=\dfrac{8}{6*2}=\dfrac{2}{3}$

Using the Distance Formula, find the distance between points (-1, -7) and (-3,-5) to the nearest tenth.

MrMuchimi

Answer:

The answer is

Step-by-step explanation:

The distance between two points can be found by using the formula

$d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-1, -7) and (-3,-5)

The distance between them is

$d = \sqrt{ ({ - 1 + 3})^{2} + ({ - 7 + 5})^{2} } \\ = \sqrt{ { 2}^{2} + ( { - 2})^{2} } \\ = \sqrt{4 + 4} \: \: \: \: \: \: \: \: \: \: \: \\ = \sqrt{8} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ = 2 \sqrt{2} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ = 2.8284271247$

We have the final answer as

<h3>2.8 units to the nearest tenth</h3>

Hope this helps you
