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 )

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

Step-by-step explanation:

It's right on edge 2020

Answer:

Step-by-step explanation:

We are expected to solve for the total number of cups, we can achieve this by adding all the individual ingredients together.

Given the number of cups poured

pretzels= 215 cups

raisins= 35 cups

peanuts= 1 cup

M&Ms= 45 cups

So the total is 215+35+1+45= 296 cups

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 :)

Expression = (y + 5,763) - (y - 8)

Simplified expression = 5,763 + 8

Step-by-step explanation:

• Note: The question is incomplete, however, the concluding part is ; write an expression, using integers to represent the difference between the elevations.

We can make y represent the sea level.

Since the highest point of the country is 5,763 feet above sea level, it Means that the expression can be written as;

y + 5,763

Also, we know that the lowest point is 8 feet below the sea level, hence expression can be written as;

y - 8

We can then find the difference(expression) between both elevation.

= (y + 5,763) - (y - 8)

When the expression is further simplified, we'll have;

5,763 + 8

The number of ways the task of Rearranging the rectangular grid can be done if no two neighboring tiles are the same color is;

P(no two neighboring tiles are same) = 60 ways

We are given;

Number of yellow tiles; n_y = 3

Number of white tiles; n_w = 2

Number of blue tiles; n_b = 1

Now, if no two neighboring tiles can be the same tile Color, it means that;

P(no two neighboring tiles are same) = number of ways when no restriction/((n_y)! × (n_w)! × (n_b)!)

>> P(no two neighboring tiles are same) = 6!/(3! × 2! × 1!)

>> P(no two neighboring tiles are same) = 720/12

P(no two neighboring tiles are same) = 60 ways

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

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

Answer:

-6

Step-by-step explanation:

-3/2 x 4/1 = 12/2

Simply to -6/1 or -6

The required temperature would be  -6°C at 4:00 pm, which is determined by the expression -3/2 × 4/1.

A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.

At midday, the temperature is 0 degrees Celsius. For four hours, the temperature decreases by -3/2 degrees Celsius per hour.

According to the given condition, we can write the expression as:

⇒ -3/2 × 4/1

⇒ -12/2

Apply the division operation to get the solution

⇒ -6

So, the time at which the temperature goes -6°C  is 4:00 PM.

Therefore, the required temperature would be  -6°C at 4:00 pm.
