Positive integers is an integer is positive if it is greater than zero. A negative integer is an integer that is negative if it is less then zero

Example: -1,-2,-3 zero is defined as nervier negative nor positive integer. Because zero is a whole number.

Positive integer is any whole number that does not have a - in front of it (eg. 1,2,3,4)

negative integer is any whole number that does have a - in front of it (eg. -1,-2,-3,-4)

Calvin evaluated -2/3 *5 1/6 using the steps below.

matrenka [14]

For this case we have to evaluate the following expression,

$- \frac {2} {3} * 5 \frac {1} {6}$

We must follow the steps below:

We convert the mixed number into a fraction:

$- \frac {2} {3} * \frac {6 * 5 + 1} {6} =\\- \frac {2} {3} * \frac {31} {6} =$

We multiply the fractions, taking into account that:

$- * + = -\\- \frac {2 * 31} {3 * 6} =\\- \frac {62} {18} =$

We simplify:

$- \frac {31} {9}$

We convert to mixed number:

$-3 \frac {4} {9}$

Answer:

$-3 \frac {4} {9}$

The highest elevation of basket dome 40 years ago was measured at 7,600 feet. what is the rate of change in elevation for this a

svet-max [94.6K]

Answer:

Rate of change in elevation = 0.6 in/year

Step-by-step explanation:

Note:

Current elevation (Missing) = 7,602 feet

Given:

Old elevation = 7,602 feet

Number of year = 7,600

Find:

Rate of change in elevation

Computation:

Change in elevation = 7,602 - 7,600

Change in elevation = 2 ft

Change in elevation = 2 x 12 = 24 inches

Rate of change in elevation = 24 / 40

Rate of change in elevation = 0.6 in/year

Hii can someone help with this pls :)

BlackZzzverrR [31]

Answer:

$R(x,y) = (0.8,-1.2)$

Step-by-step explanation:

The coordinates of QS are:

$Q(x_1,y_1) = (-2,-6)$

$S(x_2,y_2) = (5,6)$

The ratio is represented as:

$R_{m:n} = 2:3$

Required

Find the coordinates of R

The coordinates of R is calculated by:

$R(x,y) = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})$

Substitute values for m, n, x's and y's

$R(x,y) = (\frac{2 * 5 + 3 * -2}{2+3},\frac{2*6 + 3*-6}{2+3})$

$R(x,y) = (\frac{4}{5},\frac{-6}{5})$

$R(x,y) = (0.8,-1.2)$

<em>None of the options is correct</em>
