A washer and a dryer cost $669 combined. The washer costs $81 less than the dryer. What is the cost of the dryer?

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:

a. 13x and 8x +5x

B 8.1 + 8.3y and 8+24y

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: I’m not sure if I’m right, but I just divided 450 by 5 and got 90! I tried using the calculators for this sort of problems but none were any help. I think B is the one to go with!

Answer:

I can't see what the options are, but any fraction equal to 1/2 will be equal to 3:6.

Step-by-step explanation:

Treat a ratio like a fraction. In this case, 3 is the numerator and 6 is the denominator. If you reduce 3/6, you get 1/2. Fractions/ratios also equal to 1/2 or 3/6 are:

2:4

4:8

5:10

6:12

7:14

8:16

9:18

10:20

If any of these ratios are not one of the options, comment below with the choices and I will help you narrow it down.

Answer:

6:12,

Step-by-step explanation:

equivalent ratios are when all numbers in a ratio can be divided or multiplied to get a whole number. for example, 3:6. the 3 can be multiplied by 2 to get 6, and the 6 can be multiplied by 2 to get 12.

Answer: Y=0 for sure, I'd need a more exact graph to tell you other ones.

You might get away with  0<=y<4

Step-by-step explanation: Asymptote is anywhere the graphs will never cross,

The angle between the sides 6 feet and 10 feet is 93.82 degrees by using the cosine rule.

Trigonometry deals with the relationship between the sides and angles of a triangle.

A tree is growing on a hill.

In an attempt to make the tree grow straight up, a 12-foot-long wire is attached to a tree at a point 6 feet off the ground.

The wire is anchored to the ground 10 feet from the base of the tree.

We know that the cosine rule is given as

[tex]\rm Cos \theta = \dfrac{a^{2} +b^{2} - c^{2} }{2ab}[/tex]

We have

a = 6

b = 10

c = 12

Then angle will be

[tex]\rm Cos \theta = \dfrac{6^{2} +10^{2} - 12^{2} }{2*6*10}\\\\\rm Cos \theta = \dfrac{36+100-144}{120}\\\\\rm Cos \theta = \dfrac{-8}{120}\\\\\theta \ \ \ \ \ = cos^{-1} \dfrac{-8}{120} \\\\\theta \ \ \ \ \ = 93.82[/tex]

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

It can be deduced from the scale computed that the model will be 648 inches.

Since 1 foot = 12 inch

18 feet = 12 × 18 = 216 inches.

In this case, since 1 inch = 3 feet was used to create their model, the model in their scenario will be:

= 216 × 3

= 648 inches.

In conclusion, the model is 648 inches.

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

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

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.
