Answer:

50 cents or .50

Step-by-step explanation:

The rate of money earned per day will be $75 per day.

The rate of change is the change of a quantity over 1 unit of another quantity.

Most of the time the rate of change is the change with respect to time.

For example the speed 3meter/second.

As per the given,

Elena made $1,350 in 18 days.

Earning per day = ($1350/18) = $75 per day.

Hence "The rate of money earned per day will be $75 per day".

Answer:

x = -12

Step-by-step explanation:

Let's solve your equation step-by-step.

8+x=−4

Step 1: Simplify both sides of the equation.

x+8=−4

Step 2: Subtract 8 from both sides.

x+8−8=−4−8

x=−12

Answer:

[tex]x = 12[/tex]

Step-by-step explanation:

isolate the variable by dividing each side by factors that do not contain the variable

x - intercept is (-4,0)

Answer:

x- intercept = - 4

Step-by-step explanation:

The x- intercept is the value of x on the x- axis where the line crosses.

The line crosses the x- axis at x = - 4, which is the x- intercept

Step-by-step explanation:

[tex]y = mx + b \\ m = slope /gradient \\b = y - intercept[/tex]

Substitute m = 1/3 in the equation.

[tex]y = \frac{1}{3} x + b[/tex]

[tex](x,y) = (0,2)[/tex]

[tex]2 = \frac{1}{3} (0) + b \\ 2 = 0 + b \\ 2 = b[/tex]

[tex]y = \frac{1}{3} x + 2[/tex]

[tex] \large \boxed{y = \frac{1}{3} x + 2}[/tex]

Answer:

We conclude that:

[tex]\left(6g^2\:\right)\times \left(-2g^3\right)=-12g^5[/tex]            

Step-by-step explanation:

Given

The product of 6g² and -2g³ can be determined by multiplying each other such as:

[tex](6g^2\:)\times \:(-2g^3)[/tex]

Apply the rule:  a(-b) = -ab

[tex]\left(6g^2\:\right)\times \left(-2g^3\right)=-6g^2\times \:\:2g^3[/tex]

Apply exponent rule:   [tex]a^b\times \:a^c=a^{b+c}[/tex]

                          [tex]=-6g^{2+3}\times \:2[/tex]

                          [tex]=-6g^5\times \:2[/tex]

                          [tex]=-12g^5[/tex]

Therefore, we conclude that:

[tex]\left(6g^2\:\right)\times \left(-2g^3\right)=-12g^5[/tex]

Given quadrilateral EFGH with vertices at E(-4,8), F(8,4), G(5,-5) and H(-7,-1), prove using coordinate geometry that EFGH is a rectangle.

Answer:

Quadrilateral EFGH is a rectangle.l because:

EF = GH and FG = EH

Step-by-step explanation:

The formula for coordinate geometry is given as :

√(x2 - x1)² + (y2 - y1)² when we have coordinates: (x1, y1) and (x2 , y2)

For the quadrilateral EFGH with given coordinates above to be a rectangle,

EF = GH

FG = EH

Hence:

For side EF

E(-4,8), F(8,4)

= √(8 - (-4))² + (4 - 8)²

= √12² + -4²

= √144 + 16

= √160 units

For side FG

F(8,4), G(5,-5)

=√(5 - 8)² + (-5 - 4)²

= √-3² + -9²

= √9 + 81

= √90 units

For Side GH

G(5,-5) , H(-7,-1)

= √(-7 - 5)² + (-1 - (-5))²

= √-12² + 4²

= √144 + 16

= √160 units

For side EH

E(-4,8), H(-7,-1)

= √(-7 -(-4))² +(-1 - 8)²

= √-3² + -9²

= √9 + 81

= √90 units

From the above calculation, we can see that truly,

EF = GH

FG = EH

Therefore, quadrilateral EFGH is a rectangle.

Answer:

circumference = 2pi r

7.4 pi =2 pi r

divide both side by pi

7.4/2=r

3.7 = radius

Step-by-step explanation:

Answer:

To find the radius of a sphere when you have the circumference, divide the circumference by 2pi.

Step-by-step explanation:

7.4pi divided by 2pi would be 36.51753628 <—— and round that number up

Answer:

m∠1 = 30°

Step-by-step explanation:

Properties of a rhombus,

1). Sum of adjacent angles is 180°.

2). Diagonals bisects the angles of a rhombus

By property - (1)

m∠M + m∠N = 180°

120° + m∠N = 180°

m∠N = 180 - 120

         = 60°

By property - (2)

Diagonal PM will bisect the angle M.

m∠1 = m∠2

m∠1 = [tex]\frac{1}{2}(\angle N)[/tex]

       = [tex]\frac{1}{2}(60)[/tex]

       = 30°

1/10 chance

2.

2/10 chance

3.

2/10 chance

4.

0/12 chance or maybe 0/10

Step-by-step explanation:

1.1/5 chance for the number and 1/2 chance for the heads/tails so

2.2/5 chance of getting it to land on an even number + 1/2 for heads

3..2/5 chance of getting it to land on an even number and  1/2 for tails

4.you cant land a 6

Answer:

For simple interest: $50, for compound interest: $56.25

Step-by-step explanation:

Year 1) 100+100(.25) = 125

Year 2) 125+125(.25) = 125+31.25 = $156.25

156.25 - 100 = $56.25

25 x 2

Answer:

B) There is a correlation between start time and amount of tea consumed. There may or may not be causation. Further studies would have to be done  to determine this.

Step-by-step explanation:

Correlation in terms of statistics refers to the relationship that exists between two components. The extent to which the two components or data are related to each other is highlighted with correlation. The change in one component brings the same amount of change in the other component. Correlation discloses the way the variables are related.  

In the given excerpt, the correlation between start time and amount of tea consumed has been highlighted. This data is required for further research about the cause.
