Answer: 10.5 inches or .875 feet.

Step-by-step explanation:

First calculate the SPEED = Distance /Time.  So 1/2 of a foot = 6 inches  so distance of 6 inches divided by time of 4 sec = s 1.5 (inches) per sec.  So using Distance = speed x time we calculate 1.5in x 7 sec= a distance of 10.5 inches or 10.5 inches divided by 12in that is in a foot = .875 feet.

Answer:

subtract

Step-by-step explanation:

let's say 1.1-1.1 same sign? yea. subtract.

Answer:

Simplifying 19 + -4c = 17 Solving 19 + -4c = 17 Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Add '-19' to each side of the equation. 19 + -19 + -4c = 17 + -19 Combine like terms: 19 + -19 = 0 0 + -4c = 17 + -19 -4c = 17 + -19 Combine like terms: 17 + -19 = -2 -4c = -2 Divide each side by '-4'. c = 0.5 Simplifying c = 0.5

Answer:

The equivalent expression of 25 - 64 are "a), b) and c)"

The given expression is:

25 - 64

To find, the equivalent expressions are:

a) 25 + 40x - 40x - 64

=  25 - 64, is the equivalent expression.

b) 25 + 13x - 13x - 64

=  25 - 64, is the equivalent expression.

c) (5 + 8)(5 - 8)

Using the algebraic identity,

(a + b)(a - b) =

=

=  25 - 64, is the equivalent expression.

d) ( + 13)( - 13)

Using the algebraic identity,

(a + b)(a - b) =

=

=   - 169, is not a equivalent expression.

e)

Using the algebraic identity,

,  is not a equivalent expression.

∴ The equivalent expression of 25 - 64 are "a), b) and c)".

Answer: option A, B, C are equivalent to [tex]25x^4-64[/tex].

We check each option by simplifying:

A) [tex]25x^4 + 40x - 40x - 64 = 25x^4-64[/tex].

B) [tex]25x^4 + 13x - 13x - 64 = 25x^4-64[/tex]

C) [tex](5x^2 + 8)(5x^2 - 8)=(5x^2)^2-8^2=25x^4-64[/tex]

D) [tex](x^2 + 13)(x^2 - 13)=(x^2)^2-13^2=x^4-169[/tex]

E) [tex](5x^2 - 8)^2=(5x^2)^2-2(5x^2)(8)+8^2=25x^4-80x^2+64[/tex].

So option A, B, C are equivalent to [tex]25x^4-64[/tex].

Answer: Systematic sampling

Step-by-step explanation: Systematic sampling usually takes an ordered technique or process in dealing with samples. Systematic sampling could assume a randomized start point in selecting observations, However, every other successive points usually follow a fixed order or selection process. In the scenario above, the manager sampling choice involves an ordered and fixed selection process whereby every fifth sample after the initial point is considered. Hence, resulting in predictable points, such as 6th, 11th, 16th, 21st, 26th, 31st,...and so on.

The perimeter of the rectangular path is 64 ft

Rectangle is a type of quadrilateral that has its parallel sides equal to each other, opposite sides are equal to each other, and all the angle are equal to 90 degrees.

How to determine this

The perimeter of a Rectangle = 2 ( Length + Width)

Where the Width = 2 ft

Length = 28 ft longer than Width

i.e W + 28

Length = 2 + 28 = 30 ft

To calculate the perimeter if the path

Perimeter = 2( 30 + 2)

Perimeter = 2(32)

Perimeter = 64 ft

Therefore, the perimeter of the rectangular path is 64 ft

Given:

There exist a proportional relationship between x and y.

To find:

The equation which represents a proportional relationship between x and y.

Solution:

If there exist a proportional relationship between x and y, then

[tex]y\propto x[/tex]

[tex]y=kx[/tex]

where, k is constant of proportionality.

We know that, proportional relationship passes through the origin because (0,0) satisfy [tex]y=kx[/tex].

For x=0, check which equation has y=0.

In option A, [tex]y=-3(0)-2=-2[/tex].

In option B, [tex]y=9[/tex].

In option C, [tex]y=4(0)=0[/tex].

In option D, [tex]y=3(0)+1=1[/tex]

Only in option C, we have a equation of the form [tex]y=kx[/tex] with 4 as constant of proportionality and it passes through (0,0).

Therefore, the correct option is C.

Step-by-step explanation:

x = -6

sub -6 to the equation

8(-6) - 5y = -33

-48 - 5y = -33

-5y = -33 + 48

-5y = 15 (divide both sides by negative 5)

y = -3

Answer:

(-3)

Step-by-step explanation:

(-48) - 5y = -33

(-48) - (-33) = (-15)

(-15) / 5 = (-3)

(-48) - 5(-3) = -33

Answer:

The slope is -0.5 or -1/2

Step-by-step explanation:

the slope of a line is easily calculated by hand using small, whole number coordinates. The formula becomes increasingly useful as the coordinates take on larger values or decimal values.

It is worth mentioning that any horizontal line has a gradient of zero because a horizontal line has the same y-coordinates. This will result in a zero in the numerator of the slope formula. On the other hand, a vertical line will have an undefined slope since the x-coordinates will always be the same. This will result the division by zero error when using the formula.

Answer:

The farthest point is the Challenger Deep

Step-by-step explanation:

Given

[tex]Highest = +29029ft[/tex]

[tex]Least = -35,797ft[/tex]

Solving (a): The sea level

Both elevations had signs in front of them.

The sea level is the point at the neutral level, neither positive nor negative.

Hence:

[tex]Sea\ Level = 0\ ft[/tex]

Solving (b): Farthest Point.

The farthest point is the one with the highest magnitude.

Comparing

[tex]Highest = +29029ft[/tex]  to   [tex]Least = -35,797ft[/tex]

-35,797 ft has the highest magnitude.

Hence:

The farthest point is the Challenger Deep
