Step-by-step explanation:

If you are not a gerbil, then you are not a pet owner. False; if you are not a gerbil, you can be a human who owns pets.

If you are not a pet owner, then you have a gerbil. False; if you are not a pet owner then you have no pets.

If you do not have a gerbil, then you are not a pet owner. False; you could have a dog or a cat.

If you are not a pet owner, then you do not have a gerbil. True, since if you do not own any pets, you will not have any animals, so you will not have a gerbil.

Answer:

Option D is the correct option.

Step-by-step explanation:

Let the points be A and B

A ( 7 , 35 ) -----> ( x1 , y1 )

B ( 7 , 21 ) -------> ( x2 , y2 )

Now, finding the distance between these two points:

[tex] \sqrt{(x2 - x1) ^{2} + {(y2 - y1)}^{2} } [/tex]

Plug the values

[tex] = \sqrt{(7 - 7) ^{2} + {(21 - 35)}^{2} } [/tex]

[tex] = \sqrt{ {0}^{2} + {( - 14)}^{2} } [/tex]

0 raised to any positive power equals 0

[tex] = \sqrt{0 + {( - 14)}^{2} } [/tex]

When adding or subtracting 0, the quantity doesn't change

[tex] = \sqrt{ {( - 14)}^{2} } [/tex]

Reduce the index of the radical and exponent with 2

[tex] = 14 \: units[/tex]

Hope this helps...

Answer:

Bill and Ted are going to order t-shirts for there school clubs. The t-shirts will have the club logo printed on the front. Bill and Ted ask two local t-shirt companies to give them a price. * Patty's Printing charges $21.50 for each t-shirt. * Sandra's shirts has a one-time set up fee for $63 and then charges $18 for each t-sh

Step-by-step explanation:

Part 2: Table Chart:

Number of t-shirts: 2

Patty's cost: 43$

Sandra's cost: : 99$

Number of t-shirts: 4

Patty's cost: 86$

Sandra's cost: : 135$

Number of t-shirts: 6

Patty's cost: 129$

Sandra's cost: : 171$

Number of t-shirts: 8

Patty's cost: 172$

Sandra's cost: : 207$

Number of t-shirts: 10

Patty's cost: 215$

Sandra's cost: : 243$

Number of t-shirts: 12

Patty's cost: 258$

Sandra's cost: : 279$

Number of t-shirts: 14

Patty's cost: 301$

Sandra's cost: : 315$

Number of t-shirts: 16

Patty's cost: 344$

Sandra's cost: : 351$

Number of t-shirts: 18

Patty's cost: 387$

Sandra's cost: : 387$

Part 3: Patty's Printing

Linear equation = equation of a line= y=mx+b

y=21.5x

Part 4: Sandra's Shirts:

Linear equation = equation of a line= y=mx+b

y= 18x+63

Part 5: Note to Jackie

Dear Jackie, I recommend Sandra's shirts.

Write equations:

Sandra's Shirts = 18x+63

Patty's Printing = 21.5x

Sandra's Shirts: 495=18x+63 = 24 shirts

Patty's Printing: 495=21.5x = 23 shirts

Part 6: Refute Jackie

Sandra's Shirts is more expensive at the beginning, but as you buy more shirts (greater than 18), Patty's Printing becomes cheaper.

You should probably add to this, but I can't think of anything else.

Part 7: Equality

At 18 shirts (see table), the shirt cost is equal.

You should probably add to this, but I can't think of anything else.

18x+63=21.5x

Words of encouragement:

Good luck!

Answer:

d=11

Step-by-step explanation:

2d-5=17

2d = 17 +5

2d = 22

d = 22/2

d= 11

Answer:

d=11

Step-by-step explanation:

So, you have to get numbers without variables attachted to it together on one side of the equation. Hence, you have to transfer "-5" to after 17. Once it's transfered, you switch the negative sign to a positive.

2d=17+5

Add 17 and 5, 22.

2d=22

Divide 22 by 2 to get d by itself.

d=11

Answer:

29/28.

Step-by-step explanation:

Starting with:

[tex]\frac{1}{4} + \frac{2}{7} + \frac{1}{2} =[/tex]

Begin by finding a common denominator. A number that contains all of the denominators as a factor would be 28. Change each fraction to contain a denominator of 28:

[tex]\frac{7}{28} + \frac{8}{28} + \frac{14}{28} =[/tex]

Add the fractions:

[tex]\frac{7}{28} + \frac{8}{28} + \frac{14}{28} = \frac{29}{28}[/tex]

Therefore, the fractions sum up to 29/28.

Answer:

1/4 + 2/7 + 1/2

Find a number that 4,7, and 2 have in common

List the multiples o 4,7, and 2

4,8,12,15,20,24,28,32,36,40

7,14,21,28,35,42,49,56,63,70

2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40

4,7,and 2 all have 28 so 28 is the common denominator

1/4 = 1/4 x 7/7 = 7/28

you can multiply because 7/7 = 1 so you are just multiplying by 1

2/7 x 4/4 = 8/28

1/2 x 14/14= 14/28

7/28 + 8/28 + 14/28 = 29/28 or 1 1/28

Answer:

Total area = 31.5 unit²

Step-by-step explanation:

Assume 1 block = 1 unit²

Divide diagram into 3 part

1. 5 by 5 block square

2. 2 by 2 block triangle(1)

2. 3 by 3 block triangle(2)

Area of square = side × side

Area of square = 5 × 5

Area of square = 25 unit²

Area of triangle(1) = [1/2][base][height]

Area of triangle(1) = [1/2][2][2]

Area of triangle(1) = 2 unit²

Area of triangle(2) = [1/2][base][height]

Area of triangle(2) = [1/2][3][3]

Area of triangle(2) = 4.5 unit²

Total area = Area of square + Area of triangle(1) +Area of triangle(2)

Total area = 25 unit² + 2 unit² + 4.5 unit²

Total area = 31.5 unit²

Answer:

Distance of midpoints of the segments AB and CD is 24 cm.

Step-by-step explanation:

Given that

AD = 36 cm

Points C and B are in segment AB.

The ratio of distance AB:BC:CD = 2:3:4

To find:

Distance of midpoints of the segments AB and CD  ?

Solution:

The ratio of distance AB:BC:CD =2:3:4

Let AB = [tex]2x[/tex]

Let BC = [tex]3x[/tex]

Let CD = [tex]4x[/tex]

Now, it is clear that AD = AB + BC + CD

[tex]\Rightarrow 36=2x+3x+4x\\\Rightarrow 36=9x\\\Rightarrow x = 4\ cm[/tex]

Putting the value of x to find AB, BC and CD:

AB = [tex]2\times 4 = 8\ cm[/tex]

BC = [tex]3\times 4 = 12\ cm[/tex]

CD = [tex]4 \times 4 = 16\ cm[/tex]

Now, mid point of AB will be [tex]\frac{8}2 = 4\ cm[/tex] on the right side of point A.

And

mid point of CD will be [tex]\frac{16}2 = 8\ cm[/tex] on the left side of point D.

[tex]\therefore[/tex] If we subtract 4 and 8 from AD we will get distance between mid points of segments AB and CD.

So, Distance of midpoints of the segments AB and CD = 36 - 4 -8 = 24 cm.

Distance of midpoints of the segments AB and CD is 24 cm.

Answer:

0.2 < x < 11.8

Step-by-step explanation:

The triangle inequality theorem states that the sum of any two sides of a triangle must be greater than the third side, for it to form a triangle. So, we can set up 3 equations, x + 5.8 > 6, 5.8 + 6 > x, and x + 6 > 5.8. This solves out to x > 0.2, x < 11.8, and x > -0.2. We can disregard that last one, because a side can't be negative. Therefore, we know the possible range of values for x.

Answer:

14 units

Step-by-step explanation:

We apply the Theorem of reflection over parallel lines.

Theorem: The composition of two reflections over parallel lines that are h units apart is the same as a translation of 2h units.

Given that the two parallel lines are 7 units apart

h=7 units

2h= 2 X 7 =14 units

Therefore, the preimage and the final image will be 14 units apart.

A rectangle has 4 sides. Two of the sides have the same length, and the other two sides have the same length. Therefore, two sides are x+4 and the other two are equal to x.

Your equation will be (x+4)+(x+4)+x+x=48

When you solve for x, you get 10.

Since your length is x+4, you will do 4+10 which is 14 as your final answer

The range of [tex]y=\sqrt{x-5} -1[/tex]   is [tex][-1,\infty)[/tex].

Given,

[tex]y=\sqrt{x-5} -1[/tex].

We have to find the range of the expression.

Set the radicand in [tex]\sqrt{x-5}[/tex]  greater than or equal to 0  to find where the expression is defined.

[tex]\sqrt{x-5} \geq 0[/tex]

[tex]x-5\geq 0[/tex]  

Add 5 to both sides of the inequality, we get

[tex]x\geq 5[/tex]

The domain is all values of [tex]x[/tex] that make the expression defined.

Interval Notation:

[tex][5,\infty )[/tex]

Set-Builder Notation:

[tex][x|x\geq 5][/tex]

The range of an even indexed radical starts at its starting point  ( 5 , − 1 )  and extends to infinity.
