Answer:

-0.03

Step-by-step explanation:

you multiply everything in the parenthesis by -0.3

so that would give you -0.15,-0.18, and 0.3

then you add all of those together and that gives you -0.03

Hi there & welcome to brainly!

Answer:

Step-by-step explanation:

Let the co-ordinates of D be ( x , y )

Let D ( x , y ) be ( x1 , y1 ) and F ( 3 , 5 ) be ( x2 , y2 )

Midpoint of DF = E ( -2 , 2 )

Now, finding the co-ordinates of D :

[tex]\boxed{\sf{ midpoint = (\frac{x1 + x2}{2} , \frac{y1 + y2}{2} ) }}[/tex]

⇒ [tex]\sf{ ( - 2 , 2 ) = (\frac{x + 3}{2} , \frac{y + 5}{2} )}[/tex]

Equating corresponding elements, we get :

[tex]\sf{-2 = \frac{x + 3}{2} }[/tex]                                  

⇒ [tex]\sf{ -4 = x + 3 }[/tex]

⇒ [tex]\sf{ x + 3 = -4 }[/tex]

⇒ [tex]\sf{ x = -4 - 3}[/tex]

⇒ [tex]\sf{x = -7 }[/tex]

Again,

[tex]\sf{ 2 = \frac{y+5}{2} }[/tex]

⇒ [tex]\sf{y + 5 = 4 }[/tex]

⇒ y = 4 - 5

⇒ y = -1

Hence, The co-ordinates of D = ( -7 , -1 )

Hope I helped!

Answer:

22

Step-by-step explanation:

2+7=9

3*9=27

27-5=22

isosceles triangles means that the two bottom angles and sides are equal

therefore, you can set R and T equal to each other:

(15x-31)=(9x+11)

(get x to one side)

15x=9x+42

6x=42

x=7

now you can plug x back into the equations:

15(7)-31

105-31

74

R and T = 74

all triangles' internal angles = 180

therefore you can add the two angles then subtract them from 180

74+74=148

180-148=32

S should be 32 :)

Complete question :

Trevor plans on buying a car. Four banks offer the annual interest rates shown.

Which list shows these interest rates in order from greatest to least

3 1/10%, 3 2/5%, 3 1/4%, 3 1/3%

Answer:

3 2/5% ; 3 1/3% ; 3 1/4% ; 3 1/10%

Step-by-step explanation:

Arrange the given interest rates in order ; greatest to least :

To make comparison easier, we can convert the fractional values to decimal ;

3 1/10%, 3 2/5%, 3 1/4%, 3 1/3%

3 1/10% = 3 + (1/10 = 0.1) = 3 + 0.1 = 3.1%

3 2/5%, = 3 + (2/5 = 0.4) = 3 + 0.4 = 3.4%

3 1/4%, = 3 + (1/4 = 0.25) = 3 + 0.25 = 3.25%

3 1/3% = 3 + (1/3 = 0.333) = 3 + 0.333 = 3.33%

Hence, arranging in descending order (greatest to least) :

3 2/5% > 3 1/3% > 3 1/4% > 3 1/10%

3 2/5% ; 3 1/3% ; 3 1/4% ; 3 1/10%

The value of six eights minus one fourth is 1/2

An expression is a combination of numbers, variables, functions (such as addition, subtraction, multiplication or division etc.).

Example of expression includes; 5x -2 , 5/2 , x +y . When two ore more terms are joined with an operation,we can call it expression.

six eights = 6/8

one fourth = 1/4

Therefore

of six eights minus one fourth

= 6/8 - 1/4

= 6 - 2/8

= 4/8

divide through by 4

= 1/2

Therefore the value of 6/8-1/4 is 1/2

Answer:

The trip will take 4.8 hours

Step-by-step explanation:

Firstly, we need to calculate the distance from Boston to Washington

Mathematically:

Distance = speed * time

Distance = 80 mph * 6 hours = 480 miles

Now we want to calculate the time it will take a train that travels at a speed of 100 mph

Mathematically;

time = distance/speed

time = 480/100 = 4.8 hours

Step-by-step explanation:

Given that the dimension of the room is

354in by 714in

let us find the area of the room

A=354x714

A=252,756in^2

The rule say 1 person occupies 3 in^2

hence x person will occupy 252,756in^2

cross multiply we have

3x=252,756

x=252,756/3

x=84252 persons will occupy the room

Answer:

X= 128º

Step-by-step explanation:

A triangle is stated to have 180º. This means that since we know 2 sides of the triangle you can simply subtract them from one another.

Doing this you would get: 180 - 90 - 38 = 52º

Noticing that X is on a straight line, this would result in the fact that X is on a line of 180º.

Subtracting the angle we found in the triangle would result you with the answer of:

180 - 52 = 128º for the value of X

Options (C) and (E)

Step-by-step explanation:

Given polynomial is,

6x⁴+ 4x³- 7x² + 5x + 8

So all the polynomials which are (look alike) similar in terms of degree and number of terms to the given expression will be equivalent.

Option (A).

[tex]16x^{10}[/tex]

It's a monomial. So not the answer.

Option (B).

6x⁵ + 4x⁴ - 7x³ + 5x² + 8

This polynomial is a 5th degree polynomial, will not be equivalent to the given polynomial expression with 4 degree.

Option (C).

6x⁴ + 4x³ - 7x² + 5x + 8

All the terms and signs between the terms of this expression are similar to the given polynomial expression,  

Expression will be equivalent to the given polynomial expression.

Option (D)

8 + 5x + 7x² - 4x³ + 6x⁴

= 6x⁴- 4x³ + 7x² + 5x + 8

Both are similar in number of terms and degree but signs between the terms are different.

Therefore, both the expressions are will not be equivalent.

Option (E).

8 + 5x - 7x² + 4x³ + 6x⁴

= 6x⁴ + 4x³ - 7x² + 5x + 8

Since, both the polynomials are similar so they are equivalent.
