Answer question 1-15 by 6pm

Answer: (6) a      (7) b     (8) d     (9) d

Step-by-step explanation:

a) Natural Numbers:            1, 2, 3, ...

b) Whole Numbers:          0, 1, 2, 3, ...     (add zero to the Natural numbers)

c) Integers:   ..., -3, -2, -1, 0, 1, 2, 3, ...   (add negatives to the Whole numbers)

d) Rationals: Add terminating and repeating decimals to Integers.

************

e) Irrationals: Non-repeating decimals that are non-terminating.  This is its own category so cannot be a Rational number or above.

f) Real Numbers: ALL of the above (a - e) are Real numbers.

6) The variable (d) represents the number of dogs.  You cannot have a fraction of dog (rational), a negative number of dogs (integer), or zero dogs (whole) so the variable will be a NATURAL number.

7) The variable (b) represents the number of baths. You cannot have a fraction of a bath (rational), a negative number of baths (integer), but you can have zero baths so the variable will be a WHOLE number.

(8) The variable (n) represents the number of nails.  You can have a fraction of a nail so the variable will be a RATIONAL number.

(9) The variable (h) represents the number of pounds of hair.  You can have a fraction of a pound so the variable will be a RATIONAL number.

Answer:

Step-by-step explanation:

The options are not given, but we could solve and arrive at an answer

say the shorter side is x

and the longer side is x+5

we know that the area of a rectangle is given as

x*(x+5)=66

open the bracket

x^2+5x=66

x^2+5x-66=0

Find two factors of  -66  whose sum equals the coefficient of the middle term, which is   5 .

the factors are 11 and -6

splitting the middle term using the two factors  11  and  -6

x2 +11x - 6x - 66=0

x(x+11)-6(x+11)=0

(x-6)=0

x=6

(x+11)=0

x=-11

The shorter side is 6 ft and the longer side is 11 ft

Answer:

cos α = - [tex]\frac{12}{13}[/tex]

Step-by-step explanation:

Since α is in second quadrant then cosα < 0

Using the identity

sin²α + cos²α = 1 then

cosα = - [tex]\sqrt{1-sin^2\alpha }[/tex]

         = - [tex]\sqrt{1-(\frac{5}{13})^2 }[/tex]

         = - [tex]\sqrt{1-\frac{25}{169} }[/tex]

         = - [tex]\sqrt{\frac{144}{169} }[/tex]

         = - [tex]\frac{12}{13}[/tex]

Answer:

Step-by-step explanation:

Given proportions

Equations as per ratio and solution for each

c. ..................................

100 yards in 10 seconds

d. ..................................

120 heartbeats in 1 minute

Answer:

Step-by-step explanation:

c.  ratio and proportion:

25 yards   =    100 yards

  2.5 sec.             y sec.

cross multiply:

100 (2.5) = 25 (y)

simplify:

y = 250 / 25

y = 10 secs.

------------------------------------------

d.  ratio and proportion:

480 heartbeats =    z heartbeats  

     4 mins.                      1 min.

cross multiply:

4 (z) = 480 (1)

simplify:

z = 480 / 4

z = 120 heartbeats

Answer:

6 1/4

Step-by-step explanation:

Answer:

y = x + 4

Step-by-step explanation:

Let the equation of the linear function represented by the table is,

[tex]y-y_1=m(x-x_1)[/tex]

where m = slope of the line

And this line passes through the points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Slope of the given line = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

From the given table two points lying on the function are (-4, 0) and (1, 5).

Slope 'm' = [tex]\frac{5-0}{1+4}[/tex] = 1

Therefore, equation of the linear function passing through (1, 5) and slope 1 will be,

y - 5 = (x - 1)

y = x + 5 - 1

y = x + 4

Answer: the pre image is FGH

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

The triangle was translated 4 units down.

It can not be A, because it would have needed to be translated up 4 units.

It can't be C, because they are not both images, one is the starting image or the pre-image and the other is after the translation or the image.

D is incorrect because it con be determined.

Hope this helps :-)

Answer:

Arithmetic sequence

Step-by-step explanation:

It's Arithmetic sequence, because it's basically the list of integers that can be added, or subtracted by a same number every time. So, according to the following sequence shown, it shows that it's subtracting by [tex]6[/tex] every time.

Answer:

-0.55 + 0.53a

Step-by-step explanation:

              -0.55 – 0.47a + a

 To find an expression equivalent to this, we must simplify the equation to a reasonable extent;

         -0.55 – 0.47a + a

      = -0.55 + 0.53a

      = 0.53a - 0.55

The expression equivalent to the given one is -0.55 + 0.53a  or 0.53a - 0.55

Answer: 1.5x²

Step-by-step explanation:

Rule: To find the area of a triangle, multiply the base times one side, then divide the product by 2.

Step 1: Find the length of the left side using the pythagorean theorem.

a^2 + b^2 = c^2.

x^2 + 2x^2 = 3x^2

√3x² = 3x

Step 2: Multiply the base times the hypotenuse.

x * 3x = 3x²

Step 3: Divide by two

3x²/2 = 1.5x²

Answer:

That would be (-5,5)

Step-by-step explanation:

Unless I saw the photo wrong, you start at the coordinates (-3,-1). You move left 2 units to get to (-5,-1). Then you move 6 units up. That will get you to (-5,5).

Answer:

28

Step-by-step explanation:

(-1)(-7)(4)

Let’s rephrase this

(-1) * (-7) * 4

Multiple in order

(-1) * (-7) = 7

A negative times a negative equals a positive.

7 * 4= 28
