Answer:

68 11/13

Step-by-step explanation:

Answer:

68 11/13

Step-by-step explanation:

So the question wants the problem 45+25-15÷13 to be solved. With this, use the order of PENDAS to solve the problem.

First, do -15 ÷ 13

This will get you -1 2/13

Next, add 45 and 25 together to get 70.

Lastly, do 70-1 2/13 to get 68 11/13.

Answer:

-101 c.

Step-by-step explanation:

-249 + 148

= -(249 - 148)

= -101 C.

The approximate freezing point of chlorine is -101°C.

We have,

The freezing point of neon is about -249c .

The freezing point of chorine is about 148c higher.

To find the approximate freezing point of chlorine, we add 148°C to the freezing point of neon:

= -249°C + 148°C

= -101°C

Therefore, the approximate freezing point of chlorine is -101°C.

Answer:

148 = x

Step-by-step explanation:

Using the Secant and Tangent Intersection theorem we can say;

38 = 1/2 (x - 72)

38 = 1/2x - 36

74 = 1/2x

(74)/(1/2) = x

148 = x

The percentage increase from the initial population of 397,000 to 412,880 is 4%

From the question, we have the following numbers:

397,000 and 412,880.

The numbers are increments from 397,000 to 412,880.

The percentage increase is calculated as:

%Percentage = (Old number - New number)/Old Number

Substitute the numbers in the above equation

%Percentage = (412880 - 397000)/397000

Evaluate the difference

%Percentage = 15880/397000

Evaluate the quotient

%Percentage = 0.04

Express 0.04 as percentage

%Percentage = 4%

Hence, the percentage increase from the initial population of 397,000 to 412,880 is 4%

Answer:

[tex]y=-2x-15[/tex]

Step-by-step explanation:

[tex]y=mx+b[/tex].

m is the slope of the line. To find it we can do [tex]\frac{dy}{dx}[/tex] which is the difference between the y-coordinates divided by the difference between the x-coordinates.

So: [tex]\frac{dy}{dx} =\frac{-9-(-3)}{-3-(-6)} =\frac{-6}{3} =-2[/tex]. Now we have the slope, let's input a set of coordinates into the equation so that we can find the constant [tex]b[/tex].

[tex]-9=-2(-3)+b[/tex]

[tex]b=-15[/tex] - Re-arranging to get b

Now re-write the equation as we have the constants.

[tex]y=-2x-15[/tex]

Answer:

B ⊂ A

Step-by-step explanation:

We know that:

A {x|x is a polygon}

So set A is the set of all polygons.

B {x|x is a triangle}

Set B is the set of all triangles.

First, a polygon is a plane geometrical figure made of a finite sequence of straight segments.

For example, a triangle is a polygon, a rectangle is a polygon, etc.

Then, all triangles are polygons, but not all polygons are triangles.

So we can conclude that the whole set B is included in the set A.

Then the correct notation would be:

B ⊂ A

Answer:

B ⊂ A
