Answer: <em>It's an absolutely correct statement because when we divide two negative numbers even if those are decimals or not, it would given a positive number.</em>

-0.8 ÷ -0.2 = 4

-1.05 ÷ -0.5 =2.1

Step-by-step explanation: We are given statement " When you divide two negative decimals, the quotient will be greater than 0.".

<em>It's an absolutely correct statement because when we divide two negative numbers even if those are decimals or not, it would given a positive number.</em>

<em>When same sign numbers divided it always gives a positive number and a positive number is always greater than 0.</em>

Let us take some example in this support:

Example 1:

-0.8 ÷ -0.2

When we divide -0.8 by -0.2, the negative signs get cross and we can divide 0.8 by 0.2 to get 4.

We can see that 4 is a positive number and it is greater than 0.

Example 2:  

-1.05 ÷ -0.5.

Here again, when we divide -1.05 by -0.5 the negative sign get cross out and we can divided 1.05 by 0.5, which gives 2.1.

We can see that 2.1 is a positive number and it is greater than 0.

Can someone help me with this math problem please​

The number of square tiles needed is 24 tiles

The formula for calculating the area of a rectangle is expressed as:

A = LW where:

L is the length

W is the width

For the rectangle:

Area = 12 feet × 8 feet

Area = 96ft²

For the square:

Area of a square = L²

Area of a square = 2²

Area of a square = 4ft²

Determine the number of square tiles that will cover the patio.

Number of square tiles needed = Area of rectangle/Area of square

Number of square tiles needed = 96/4

Number of square tiles needed = 24

Hence the number of square tiles needed is 24 tiles.

Scientists modeled the intensity of the sun, I, as a function of the number of hours since 6:00 a.m., h, using the
MAVERICK [17]

The functions are illustrations of composite functions.

<em>The soil temperature at 2:00pm is 67</em>

The given parameters are:

\mathbf{I(h) =\frac{12h - h^2}{36}} ---- the function for sun intensity

\mathbf{T(I) =\sqrt{5000I}} -- the function for temperature

At 2:00pm, the value of h (number of hours) is:

\mathbf{h = 2:00pm - 6:00am}

\mathbf{h = 8}

Substitute 8 for h in \mathbf{I(h) =\frac{12h - h^2}{36}}, to calculate the sun intensity

\mathbf{I(8) =\frac{12 \times 8 - 8^2}{36}}

\mathbf{I(8) =\frac{32}{36}}

\mathbf{I(8) =\frac{8}{9}}

Substitute 8/9 for I in \mathbf{T(I) =\sqrt{5000I}}, to calculate the temperature of the soil

\mathbf{T(8/9) =\sqrt{5000 \times 8/9}}

\mathbf{T(8/9) =\sqrt{4444.44}}

\mathbf{T(8/9) =66.67}

Approximate

\mathbf{T(8/9) =67}

Hence, the soil temperature at 2:00pm is 67

Solve for g.<br><br> 8g + 3 = –6g + 13g + 13
pav-90 [236]

Answer: g = 10

Step-by-step explanation: 8g + 3 = –6g + 13g + 13

                                             8g + 3 = (–6g + 13g) + (13)

                                             8g + 3 = 7g + 13

                                             8g + 3 - 7g = 7g + 13 - 7g

                                             g + 3 = 13

                                             g + 3 - 3 = 13 - 3

                                             g = 10
