Answer:

x = 2.25

Step-by-step explanation:

8:6

So, 8/6 = 4/3 or 1.33333333 (decimal multiplier)

Therefore, 8 divided by 4/3 = 6.

Then, we could also do 3 divided by 4/3= 9/4 or 2.25.

2.25 x 4/3 = 3.

Answer:

x = 2.25

setting up proportionality:

[tex]\rightarrow \sf \dfrac{8}{3} = \dfrac{6}{x}[/tex]

[tex]\rightarrow \sf 8x = 18[/tex]

[tex]\rightarrow \sf x = \dfrac{18}{8}[/tex]

[tex]\rightarrow \sf x = 2.25[/tex]

Answer:

x/2 + y√3/2 = 4

Step-by-step explanation:

Step 1: Apply formula

Formula for this problem is :-

xcosα + ysinα = p

Step 2: Substitute values

xcos(60°) + ysin(60°) = 4

x(1/2) + y(√3/2) = 4

x/2 + y√3/2 = 4

Answer:

15x-36

Step-by-step explanation:

let's simply get the area of the larger square, and then get the area of the smaller square and subtract the area of the smaller square from that of the larger square, what's leftover is the shaded region.

[tex]\stackrel{\textit{area of the larger square}}{(4x-6)(4x-6)\implies \stackrel{F~O~I~L}{16x^2-48x+36}} ~\hfill \stackrel{\textit{area of the smaller square}}{(x)(x)\implies x^2} \\\\[-0.35em] ~\dotfill\\\\ (16x^2-48x+36)~~ - ~~(x^2)\implies 15x^2-48x+36 \\\\\\ 3(5x^2-16x+12) \implies 3(5x-6)(x-2)[/tex]

Answer:

49.55

Step-by-step explanation:

okay so, what we do is
Get 15% of 23
Get 15% of 32

15% of 23 is 3.45

15% of 32 is 4.80

Now we do

23 - 3.45

32 - 4.80

23 - 3.45 is 19.55

32 - 4.80 is 27.2

This is the part im not 100% on

27.20 + 19.55 is 46.75

6% of 46.75 is 2.80

46.75 + 2.80 is 49.55

Now i dont know if its that way or if you apply the 6% sale tax to each individual item

Question: A clothing store is having an anniversary sale. Every piece of clothing in the

store is 15% off. If Lara bought a belt that was originally priced $23 and a

sweater that was originally $32, what is the final price after 6% sales tax?

Answer: $44.89

Step-by-step explanation:

23+32=55

15% of 55 = $8.25

leaves $47.75

6% of 47.75 = $2.87

leaves $44.89

Answer:

x=9

y=[tex]9\sqrt{2}[/tex]

Step-by-step explanation:

This is a special type of triangle known as a 45-45-90 triangle.

The ratio for the sides of this triangle are x:x:x[tex]\sqrt{2}[/tex]

Meaning that the two sides other than the hypotenuse are equal, so in this triangle x=9 because it is not a hypotenuse.

The hypotenuse, however, is the value of one side multiplied by [tex]\sqrt{2}[/tex].

In this case it is 9, so 9*[tex]\sqrt{2}[/tex] = [tex]9\sqrt{2}[/tex]

The length of kite’s shorter diagonal is 39 inches.

A kite is a quadrilateral (has four sides and four angles) in which adjacent sides are congruent and the diagonal bisect at 90 degrees.

Each leg of the upper triangle measures 41 inches and each leg of the lower one measures 50 inches. Hence half the length of the base = 80/2 = 40. The base = diagonal = 80 inches

Using Pythagoras:

41² = d₁² + 40²

d₁ = 9 inches

Also:

50² = d₂² + 40²

d₂ = 30 inches

Length of diagonal = 9 + 30 = 39 inches

The length of kite’s shorter diagonal is 39 inches.

Answer:

100/7 --> 50/3.5 --> 25/1.75 . If we're assuming, without a calculator, we can just say 1.75 ~ 2. So 25/2 = 12.5 as an approx .

But actually, 100/7 -- with no assumptions etc, is just 14.28571429
