Step-by-step explanation:

If Melinda has 4 different crayon and 2 different boxes and she is to put all 4 crayons into the two boxes so that each box has at least 1 crayon, this  can be achieved as follows. Note that at least one crayon must be in each box, this means no box must be left empty. Each box can take any number of crayon from 1 and above.

First box      Second box

1 crayon        3 crayons (first way)

2 crayons     2 crayons (2nd way)

3 crayons     1 crayon (3rd way)

This means that crayons can be divided into each box in 3 different ways provided that each box has at least 1 crayon.

The result is number [tex]r[/tex] where:

[tex]r=(120+120\cdot\frac{d}{100})+(120+120\cdot\frac{d}{100})\cdot\frac{25}{100}[/tex]

Answer:

0,.96 : 0.04 =24

Step-by-step explanation:

96 : 4 = 24 because 24 * 4 is 96

9.6 : 0.4 = 24 because 24 * 0.4 = 9.6

0.96 : 0.04 = 24 because 24 * 0.04 = 0.96

or

0.96 / 0.04 = 9.6 / 0.4 = 96 / 4 = 24

Answer:

Rate of power generation when the sky is cloudy= 5 watts per hour.

Rate of power generation when the sky is clear = 32 watts per hour.

Step-by-step explanation:

A large solar panel can generate power at a maximum rate of 400 kilowatts per day.

Let the number of hours when the sky is cloudy =C

Let the number of hours when the sky is clear = L

Given the inequality:

[tex]5C+32L \leq 400[/tex]

The rate at which the solar panel generates power when the sky is cloudy is 5 watts per hour.

The rate at which the solar panel generates power when the sky is clear is 32 watts per hour.

Answer:

Angle 1: 55

Angle 2: 110

Angle 3: 15

Step-by-step explanation:

Angle 1: x

Angle 2: 2x

Angle 3: x-40

The total degrees for all the angles in a triangle add up to 180, so we now have the equation x+2x+x-40=180. From here we solve to get 55 degrees for x, so angle 1 is 40 degrees, angle 2 is 110 (2 times 40) and the third angle is 15 (55-40).

Answer: 125

Step-by-step explanation:

4/25 = 20/Y

Cross multiply to get the equation

4Y = 500

Divide both sides by 4

Y=125

y=5 when x=20.

Given that, y is inversely proportional to x. When y = 25 , x = 4.

We need to find the y value when x=20.

Inversely proportional variables or quantities are those in which if one variable increases the other will decrease, and if one variable decreases the other increases.

Now, y∝1/x

⇒y=k/x

⇒25=k/4

⇒k=100

Thus, the y value when x=20.

y=100/20=5

Therefore, y=5 when x=20.

Answer:

B. 8

Step-by-step explanation:

This is because a 6-8-10 right triangle (a variation of a 3-4-5 right triangle) is a Pythagorean Triple.

To show that the answer 8 works:

a^2+b^2 = c^2

6^2+b^2 = 10^2

36+b^2 = 100

b^2 = 64

b = sqrt64 = 8

Answer:

x=8

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2

6^2 + x^2 = 10 ^2

36+ x^2 = 100

Subtract 36 from each side

x^2 = 64

Take the square root of each side

x = 8

Answer: 36 miles

Step-by-step explanation: Multiply 12 by 3 to find out how many miles a person will walk in an hour.

12 miles = 20 minutes

12 x 3 = 36

36 minutes in 1 hour

Answer:

36 miles

Step-by-step explanation:

convert the one hour into minutes, which will be 60 minutes.

if 12 miles = 20 minutes,......................... what about 60 minutes.

     ??        =  60 minutes.

cross multiply:

it will become; 12 ×60 ÷20

[tex]A2+By=C[/tex]

Step-by-step explanation:

Well standard form is [tex]Ax+By=C[/tex].

And we have x = 2 meaning that x is 2 so the standard is [tex]A2+By=C[/tex].

So basically if we know that x is 2 and x is in the standard for equation we can just plug it in.

So [tex]Ax+By=C[/tex]

x -> 2

So answer is [tex]A2+By=C[/tex]

2A+By=C is the standard form of X=2

Two or more expressions with an Equal sign is called as Equation.

The standard form of a linear equation is Ax+By=C.

A times of x plus B times of y equal to C

A, B, and C are constants,

x and y are variables.

Standard form lets us quickly find the x- and y- intercepts.

By given x value is 2.

Now plug in the value of x in standard form of equation.

2 times of A plus B times of y equal to C

2A+By=C

Hence 2A+By=C is the standard form of X=2

Answer:

x=62

Step-by-step explanation:

In an isosceles triangle opposite sides are equal and sum of the sides is 180 degree

So, if we name them 'angle a', 'angle b' and 'angle c'

angle a= 56

a+b+c= 180

using the isosceles triangle formula b=c,

56+b+c=180

name b,c as x

56+2x=180

2x= 180-56

2x= 124

x=62

The value of x in the triangle will be 62°

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

Two sides of triangle = 6

So, This is an isosceles triangle.

Third side of a triangle = 5.7

Now,

Since, The given triangle is an isosceles triangle.

So, It has measure of two angles = x°

And, The measure of third angle = 56°

Since, The sum of all angles of a triangle = 180°

Substitute all the value of angles, we get;

x° + x° + 56° = 180°

Solve for x as;

2x + 56 = 180

Subtract 56 both side,

2x + 56 - 56 = 180 - 56

2x = 124

Divide by 2, we get;

x = 62°

Thus, The value of x in the triangle will be 62°

Answer: Y = 2 ; 3 ; 4

Step-by-step explanation:

Given the rule : y=1/4x + 1

X = 4, 8, 12

When x = 4

y = 1/4(4) + 1

y = 1 + 1

y = 2

When x = 8

y = 1/4(8) + 1

y = 8/4 + 1

y = 2 + 1

y = 3

When x = 12

y = 1/4(12) + 1

y = 12/4 + 1

y = 3 + 1

y = 4

Therefore ;

X - - - 4 - - - 8 - - - 12

Y - - - 2 - - - 3 - - - 4
