Answer:

B.) 7.5

Step-by-step explanation:

I'm guessing that 7.5 is the radius. If so, the diameter is 15 in. because 7.5 + 7.5 = 15. The radius is half of the diameter.

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:

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

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

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:

its 7=4x

Answer:

$97.07

Step-by-step explanation:

7.5% of 74.96 is 5.62

18% of 74.96 is 13.49

74.96+5.62+13.49=97.07

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.

Slope is 1/4

Step-by-step explanation:

Slope=Rise/Run=(y2-y1)/(x2-x1)=(9-6)/(5-(-7))=3/12=1/4

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:

4/5

Step-by-step explanation:

The slope of the line is 4/5.

To find out the slope of a line, you must remember rise over run. Using that, you count up from whenever the line meets an actual whole number, which in this case it is -2, and then count up 4, and then you start counting right to meet the point (3, 4). The number of spaces you go to the right is 5, making the slope 4/5.

Hope this isn't too confusing and that it helps :)

Jada would have brought 90 clementines for all those people.

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.

Here,
For 40 people number of clementines be x,
So, as for the proportional relationship.
16 / 36 = 40 / x
x = 40 [36/16]
x = 10[9]
x = 90

Thus, Jada would have brought 90 clementines for all those people.

Given parameters:

Charge per month  = $65

Percentage on rent= 6%

Amount paid by Jack per month = $164

Unknown:

Monthly rent on his property = ?

Solution:

  Monthly rent on his property can be found by;

  Amount paid by Jack per month = Charge per month + 6% of monthly rent

Let the monthly rent = x ;

  So;

              164  = 65 + [tex]\frac{6}{100} x[/tex] x

              164 - 65  = [tex]\frac{6x}{100}[/tex]

                   99  = [tex]\frac{6x}{100}[/tex]

                   6x = 9900

                    x = 1650

Monthly rent on his property is $1650

Answer:

the value of y is -3

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
