Answer:

file?

Step-by-step explanation:

Given:

Numbers on die = 1, 2, 3, 4

Colors on board = Red, Green, Blue, Orange (equal sized sections)

To find:

The number of different possible outcomes are there if she rolls a fair die in the board.

Solution:

According to the given information,

The total possibilities for numbers = 4

Total possibilities for colors = 4

Total possibilities = Possibilities for number × Possibilities for colors

                             = [tex]4\times 4[/tex]

                             = [tex]16[/tex]

So, total 16 possible outcomes are there if she rolls a fair die in the board.

Let Red=R, Green=G, Blue=B, Orange=O, then list of total possible outcomes is:

{1R,1G,1B,1O,2R,2G,2B,2O,3R,3G,3B,3O,4R,4G,4B,4O}

Therefore, the total possible outcomes are 16 and the lies of outcomes is {1R,1G,1B,1O,2R,2G,2B,2O,3R,3G,3B,3O,4R,4G,4B,4O}.

Answer: 8

Step-by-step explanation:

i saw one like the answser it said do 4 x 4 and got 16 then i answer it and got it wrong so i did 4 plus 4

Answer: Number 1 is c=89 ft

Number 2 is b=3 cm

Step-by-step explanation: a²+b²=c²

For number 1, 39 ft is a and 80 ft is b so

39²+80²=c² so 39² is 39x39=1521 and 80² is 80x80=6400 so 6400+1521=7921

7921=c² and the square root of 7921 is 89 so c=89 ft

For number 2, a=1.6 cm and c=3.4 cm so 3.4²-1.6²=b²

3.4² so 3.4x3.4 which is 11.56

1.6² so 1.6x1.6 which is 2.56

11.56-2.56=c² and 11.56-2.56=9

Square root of 9 is 3 so b=3

So number 2 answer is b=3 cm

Answer:

5

Step-by-step explanation:

Terrible wording on the question as the "father" is 15 the "son" is 10 and the sister is 0 or just born

J = john

S = son

X = sister

J = 2s

S = 5 + X

3(x+5) = J + 5

J = 2(5+x) = 2x + 10

3x+15 = 2x +10 + 5

x = 0

Step-by-step explanation:

Answer:

The sum of the first 7 terms in the geometric sequence is -6558

Step-by-step explanation:

s7 refers to the sum of the first 7 terms of the geometric sequence

To calculate the sum of terms, we use the sum of terms formula

We have this generally given as;

Sn = a(1-r^n)/(1-r)

a refers to the first term, given as a1 which is -4374

r is the common ratio which is 1/3

n is the number of terms, which is 7

substituting these values;

s7 = -4374(1-(1/3)^7)/(1-1/3)

s7 = -4374(1-(1/3)^7)/2/3

s7 = (3 * -4374)/2 * (1- (1/3)^7

s7 = -6561 * (1-1/2187)

s7 = -6561 * (2187-1)/2187

= -6561 * 2186/2187

= -6558

The work required to lift the massive car of 2400 kg is more than lifting the car with 120 kg

Work is defined as the energy that is applied to or removed from an object by applying force along a displacement. For a constant force acting in the same direction as the motion, the work is defined as the product of the force's magnitude and the distance traveled. The dimensions of work is

ML²T⁻² and the SI unit of work is Joule

Work = Force x Distance

The SI unit for work is the joule (J), or newton meter ( Nm ). One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m

Given data ,

Let the work required to move the 2400kg car be W₁

Let the work required to move the 1200kg car be W₂

Now , the force in moving the 2400 kg car = F₁

The value of F₁ = 2400 ( a )

And , the force in moving the 1200 kg car = F₂

The value of F₂ = 1200 ( a )

where a is the acceleration

Let the distance moved be height H

Now , the work W₁ = Force x Distance

Substituting the values in the equation , we get

W₁ = 2400 ( a ) H

And , W₂ = 1200 ( a ) H

Now , W₁ > W₂

Hence , the work required to move 2400 kg car is greater

Answer: a2 + b2 = c2 a2 + b2 = c2 is correct

Step-by-step explanation:

reason being:

if a2 and b2 are in the equation that would make c2 a2 rational and when the number is rational thats automatically easy to know the area and square root and thats the key! the questions states the spuare root and area which makes it all easy to know that the correct one is a2 + b2 = c2 a2 + b2 = c2.

Answer:

your answer will be 25 .....ok

Answer:

x = 25

Step-by-step explanation:

Given y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 3 when x = 15

3 = 15k ( divide both sides by 15 )

[tex]\frac{3}{15}[/tex] = k, that is k = [tex]\frac{1}{5}[/tex]

y = [tex]\frac{1}{5}[/tex] x ← equation of variation

When y = 5 , then

5 = [tex]\frac{1}{5}[/tex]x ( multiply both sides by 5 to clear the fraction )

25 = x

Answer:

X=4, y=-7

Step-by-step explanation:

To use elimination method, you want to cancel x or y when adding the equations together. So let’s multiply the first equation by -2

2(y)=2(-x-3)

2y=-2x-6

——————

add above equation 2y=-2x-6

to second equation    Y=2x-15

add together.           3y=-21

                                   Y=-7

—————————————-

solve for x by substituting y value (7) into either equation

y=-x-3

-7=-x-3

-4=-x
