I need to write an algebraic expression that includes 2 constatants, 2 variables, and 2 different operations. It also need it in word form as well as number form. NEED HELP ASAP BEEP HELP ASAP

Answers

Answer:

An example would be

(x+3)-(y+12)

The two constants are 3 and 12 (I'm assuming you meant "constant" as in the number that stands by itself and not "constatant" lol)

The two variables are x and y

The two operations are addition and subtraction

In words you could say "the quantity of x plus three minus the quantity of y plus twelve"

Ben rolled a number cube numbered one through six. It landed on an odd number 30 times. What is the probability that it lands on an odd number on the next roll?

Answers

Answer:

1 /2

Step-by-step explanation:

Sample space of number cube : (1, 2, 3, 4, 5, 6)

Odd numbers on cube : (1, 3, 5) = 3 odd numbers

Since each roll of number cube is independent, the number of times it has landed between fire does not matter :

Therefore, probability of landing on a odd number is :

P = required outcome / Total possible outcomes

P = 3 / 6

P = 1/2

During a basketball game, one of the players scores 8 points for her team. If the points she scored represent 20% of the team's total points, as shown below, how many points did the team score during the game?

Answers

Answer:

40points

Step-by-step explanation:

Given data

Let the total points the team scored be x

so that

20% of x= 8 points

let us solve for x

20/100*x= 8

0.2*x= 8

0.2x= 8

Divide both sides by 0.2

x= 8/0.2

x= 40 points

Hence the time scored 40points

What is the relationship between the corresponding angle bisectors BD and XZ?

Answers

Answer:

XZ = 2.5 BD

Step-by-step explanation:

Comparing the two triangles,

[tex]\frac{BD}{BC}[/tex] = [tex]\frac{XZ}{XY}[/tex]

[tex]\frac{6}{8}[/tex] = [tex]\frac{XZ}{20}[/tex]

⇒ XZ = [tex]\frac{20*6}{8}[/tex]

         = 15

XZ = 15

So that,

BD:XZ = 6:15

           = 1:2.5

Therefore, the relationship between BD and XZ is XZ = 2.5 BD.

If the perimeter of a rectangular picture frame must be less that 200 in, and the width is 36 in. what must the height H of the frame be?

Answers

Answer:

w = width

h = height

2(w+h) < 200

w + h < 100

since w = 36, then

36 + h < 100

h < 100 - 36

h < 64

Step-by-step explanation:

The perimeter of the rectangular picture frame can be calculated by the equation,

                                 2h + 2w = P

where h and w are height and width , respectively. Substituting the known values and the condition for the inequality,

                                2h + 2(36 in) < 200

The inequality gives h as,

                                          h < 64

Thus, the answer is letter A.

Answer:

the equation in numbers looks like this: 6xK-4=2xK+4 and if you are solving this equation it is equal to 0

Step-by-step explanation:

to get to 0 you first need to cancel out the equal terms on both sides so it should look like this: 6K=2K

then you move the variable to the left hand side and change its sign so it should look like this:6K-2K=0

then you collect the like terms so it should look like this: 4K=0

and then you divide both sides by 4 and it should get you K=0

Joshua drove his car a distance of 321.7 miles, and it required 13.6 gallons of gasoline (petrol). How many liters of fuel will it take to go 100 kilometers?

Answers

Answer:

1005.68 litres

Step-by-step explanation:

Steps to answering this question

Convert miles to kilometers and gallons to litresThen divide the converted miles by the converted gallons Multiply the value gotten from the above step by 100 km

1 gallon = 3.78541 litres

13.6 gallons x 3.78541 = 51.48 litres

1 mile = 1.60934 km

321.7 miles x 1.60934 = 517.72 km

Litre needed per kilometer =  517.72 km / 51.48 = 10.06

Litres needed for 100 km = 100km x 10.06 = 1005.68 litres

Answers

Answer:

The correct approach is Option A (-4).

Step-by-step explanation:

The given values are:

Vertex of the parabola,

(h, k) = (3, 5)

Passing through,

(x, y) = (-1, 6)

As we know,

The equation of parabola is:

⇒  [tex]x=a(y-k)^2+h[/tex]

On substituting the given values in the above equation, we get

⇒  [tex]-1=a(6-5)^2+3[/tex]

⇒  [tex]-1=a+3[/tex]

On substracting "3" from both sides, we get

⇒  [tex]-1-3=a+3-3[/tex]

⇒           [tex]a=-4[/tex] (coefficient of squared term)

Thus the above is the right choice.
