Answer:

$698.75

Step-by-step explanation:

Washer - 350$

Dryer - 300$

Total of these two items = 650$

1% of 650$ = 6.5$

$6.5 x 7.5% = 48.75

Tax - 48.75$

350 + 300 + 48.75 = 698.75

Answer:

  x = 8

Step-by-step explanation:

In this geometry, all of the triangles are similar right triangles. That means corresponding sides are proportional. The proportion you write will express that relation for the sides you are given.

  long side / short side = x/4 = 4/(x-6)

Multiplying this proportion by 4(x-6) gives ...

  x(x -6) = 16

We can add 9 to complete the square.

  x^2 -6x +9 = 16 +9

  (x -3)^2 = 25

  x -3 = 5 . . . . . . . take the square root (only the positive root is of interest)

  x = 8 . . . . . . . . . add 3

I think the right Answer 8/3

Answer:

8/3

Step-by-step explanation:

This hanger is in balance. there are 2 labeled weights of 4 grams and 12 grams the 3 circles have the same weight.

We have to determine,

What is the weight of each circle?​

According to the question,

Let the weight of each circle be x.

This hanger is in balance. there are 2 labeled weights of 4 grams and 12 grams the 3 circles have the same weight.

The hanger is in the balanced state then the sum of all weight of the left-hand side is equal to the sum of all weight of the right-hand side.

Left hand side weight = x+ x + x+ 4 = 3x+4

Right hand side weight = 12

Then,

The hanger is in a balanced state, the weight of each circle is given by,

The weight of the left-hand side = the weight of the right-hand side

The value of x is 8/3.

Hence, The weight of each circle is 8/3.

Mr. Kelly knows that one side of his house is 20 feet long and it takes him six strides to walk the same distance. How long

is the other side of his house if it takes him 8.5 strides to walk it?

28.33 ft

Let that be x

Ratio remains same

[tex]\\ \rm\rightarrowtail \dfrac{6}{20}=\dfrac{8.5}{x}[/tex]

[tex]\\ \rm\rightarrowtail 6x=20(8.5)[/tex]

[tex]\\ \rm\rightarrowtail 6x=170[/tex]

[tex]\\ \rm\rightarrowtail x=170/6[/tex]

[tex]\\ \rm\rightarrowtail x=28.3ft[/tex]

Step-by-step explanation:

1) A corresponds to F (your screen shot is cut off, that option is not shown)

2) E) B corresponds to D

3) F) C corresponds to E

4) H) angle A corresponds to angle F

5) B) angle B corresponds to angle D

6) A) angle C corresponds to angle E

7) C) side AB corresponds to side FD

8) D) side BC corresponds to side DE

9) G) side AC corresponds to side FE

10) A.

of course they are similar. being congruent means that if you turn them to have the same orientation and then move them on top of each other, they cover each other up perfectly. so, in essence, they are even equal.

of course, being equal makes them also similar ...

11. D.

12. A.

Answer:

D is correct

Step-by-step explanation:

First we find 20% of the price and subtract it

[tex]45*0.20=9\\45-9=36[/tex]

Next we find how much tax would be

[tex]36*0.0825=2.97[/tex]

then we add the two amounts together to get the final price

[tex]36+2.97=38.97[/tex]

Answer:

An irrational number is a real number that cannot be expressed as a ratio of integers, for example, √ 2 is an irrational number. Again, the decimal expansion of an irrational number is neither terminating nor recurring.

Step-by-step explanation:

An Irrational Number is a real number that cannot be written as a simple fraction: 1.5 is rational, but π is irrational.

√2, √3, √5, √11, √21, π(Pi) are all irrational.

The approximate surface area of this right triangular prism is 193.2cm

The surface area of a triangular prism is expressed as:

Surface area = (Perimeter of the base × Length of the prism) + (2 × Base Area)

Perimeter of the base = 6 + 6 + 6

Perimeter of the base = 18cm

Length of the prism = 9cm

Base area = 1/2 * 5.2 * 6
Base area  = 15.6cm

Determine the surface area

Surface area = (18 * 9) + 2(15.6)

Surface area = 162 + 31.2

Surface area = 193.2 cm

Hence the approximate surface area of this right triangular prism is 193.2cm

Answer:

I think you need to draw it with graph.

Step-by-step explanation:

Kareem plans to get eight hours of sleep but looses a half hour of sleep every time his dog barks. Therefore between his hours of sleep (h) and number of dog barks (b) will be:

h = 8 – (b/2)

So that if b = 0,

Kareem’s hours of sleep:

h = 8-(0/2)

= 8-0

= 8

if b = 5

h = 8 -(5/2)

h = (16-5)/2

h = 11/2

h = 5.5

And...Draw a graph about it

Answer:

  AD ≈ 80

Step-by-step explanation:

The Pythagorean theorem can be used to write and solve relations between the various edges and diagonals.

AE is the hypotenuse of ΔABE, so you have ...

  AE² = AB² +BE²

  BE² = AE² -AB² = 65 -52 = 13

__

AD is the hypotenuse of ΔACD. We presume the figure is a rectangular prism, so CD = BE. Then you have ...

  AD² = AC² +CD²

  AD² = 80² +13 = 6413 . . . . . CD² = BE² = 13

  AD = √6413 ≈ 80.081

  AD ≈ 80

Answer:

x = 10

Step-by-step explanation:

Since the pentagons are similar you can say...

4x cm/48 cm = x cm/(x+2) cm

Now do cross multiplication with this equation, so 4x is multiplied with (x+2) and 48 is multiplied with x... you end up with:

4x^2+8x = 48x, now subtraction 8x from 48 x....

4x^2 = 40x, and divide one x from each side

4x = 40, therefore x = 10

Answer:

3 vertices

Step-by-step explanation:

Vertices are the "points" of a 2D figure. In this case, we see the 2D figure as a triangle. There are 3 points on the triangle, so there are 3 vertices.

x = -8

x = 3

x = -15

The explanation:

5x + 20 = 3x + 4

5x = 20 - 20 = 3x + 4 - 20

subtract = subtract = 5x = 3x - 16

5x = 3x - 16

5x - 3x = 3x - 16 - 3x

7x - 4 = 3x + 8

7x - 4 + 4 = 3x + 8 + 4

7x = 3x + 12

7x = 3x + 12

7x - 3x = 3x + 12 - 3x

2x + 6 = x - 9

2x + 6-6 = x - 9-6

2x = x - 15

2x = x - 15

2x - x = x - 15 - x

x = - 15
