HELPPPPPP!!!!! ASAPPPPPPP!!!!!!!!

Which of the following expressions is correctly written in scientific notation?

Answer:

The sum of the measures of the angles of a convex quadrilateral is 360° as a convex quadrilateral is made of two triangles. Yes, this property also holds true for a quadrilateral which is not convex. This is because any quadrilateral can be divided into two triangles.

Answer: i would say 280.

Step-by-step explanation: because if you add 180 plus another set of it it would make 280

Answer:

180

Step-by-step explanation:

Since they are vertical angles, they are congruent to each other

m<1 = m<2

Answer:

Square is a rhombus. (option b)

Answer:

11.1

Step-by-step explanation:

x=4

2x+3.1

You need to plug in the 4 into the x in the equation above

2(4)+3.1

8+3.1=11.1

Answer:

11.1

Step-by-step explanation:

here's your solution

=> the value of x = 4

=> the given expression is = (2x + 3.1)

=> putting the value of x in expression

=> 2*4 + 3.1

=> 8 + 3.1

=> 11.1

hope it helps

(2.7×10^-3) ÷ (9×10^7) | Given (thanks for proper formatting :')

(2.7 × 0.001) ÷ (9 × 10,000,000) | Start with exponents

0.0027 ÷ 90,000,000 | Multiply what's in the parenthesis

243,000 | Divide these numbers

Answer:

1st and 2nd option are the correct answers.

Answer:

142.5 in^2

Step-by-step explanation:

First, find the area of the rectangle

19*10= 190

Now find the area of the triangle

A=1/2bh

A=1/2(19)(10-5)

A=47.5

Since we need the shaded region, subtract the triangle area from the rectangle area

190-47.5=142.5

Answer:

f(x) = (x + 1)(x + 2)

Step-by-step explanation:

Zero x = -1 corresponds to factor x + 1, and zero x = -2 to x + 2.  Thus, the quadratic in question is

f(x) = (x + 1)(x + 2)

Answer:

$10,530

Step-by-step explanation:

I = Prt

P = 19500

r = 0.06

t = 9

I= 19500 x 0.06 x 9

I = 10530

Step-by-step explanation:

Given the equation : 2x-4=20

By adding 4 1 - tiles to each side, this will eleminate the constant term on the left hand side where the Coefficient we wish to solve for lies. Hence, the same exact treatment given to data on the right hand side is done to the data in the left. Hence, the method will work as it will give ;

2x - 4 = 20

2x - 4 + 4 = 20 + 4

2x = 24 ( constant eliminated)

x = 24/4

x = 6

Answer:

x = 6.125

Step-by-step explanation:

y  = -2 + 34

so

-2x + 34 = 6x - 15

+2x           +2x      

34 = 8x - 15

+15        +15

49 = 8x

x = 6.125

Answer:

Play 3

Step-by-step explanation:

Given:

[tex]\left\begin{array}{ccccc}{Play}&{1}&{2}&{3}&{4}&{Yards}&{+4}&{-6}&{-2}&{+3}\end{array}\right[/tex]

Required [Missing from the question]:

Determine the play with the least change in yard?

To do this, we ignore the sign in front of each yard before we analyze.

So, we have:

Play 1 has a change of 4

Play 2 has 6

Play 3 has 2

Play 4 has 3

From the above analysis, play has the least (which is 2)

Answer:

Equilateral triangle

Isosceless triangle

Scalene triangle.

Step-by-step explanation:

- If all the sides of the triangle are equal, the triangle is said to be an equilateral triangle.

- If 2 sides of the triangle are equal, the triangle is said to be an Isosceless triangle

- If no side of the triangle is equal, the triangle is said to be a scalene triangle.

Answer:

x = 47

Step-by-step explanation:

3x - 2 + 41 = 180 {Supplementary}

3x   + 39 =  180

        3x   = 180 - 39

       3x  = 141

          x = 141/3

x = 47

-7 = 1 + 2/3n

Subtract 1 from both sides:

-8 = 2/3n

Multiply both sides by 3:

-24 = 2n

Divide both sides by 2:

N= -12

Answer:

n=-12

Step-by-step explanation:

Okay this isn't to hard first in the equation you must subtract 1 from both sides

So this: -7=1+2/3n

Becomes This: -8=2/3n

Then I divided by 2 on both sides to get:-4=1/3n

Then I multiplied by three to get -12=n
