3/4 is 0.75

Answer:

[tex]W = 18[/tex] -- Width

[tex]H = 14[/tex] --- Height

Step-by-step explanation:

Given

[tex]V = 4284[/tex] -- Volume

[tex]L = 17[/tex] -- Length

[tex]H = ??[/tex] -- Height

[tex]W = 4 + H[/tex] -- Width

Required:

Find the height and the width

Volume is calculated as:

[tex]V = LWH[/tex]

This gives:

[tex]4284 = 17 * (4+H) * H[/tex]

[tex]4284 = 17 * (4H+H^2)[/tex]

Open bracket

[tex]4284 = 17 * 4H+17*H^2[/tex]

[tex]4284 = 68H+17H^2[/tex]

Divide through by 17

[tex]252 = 4H+H^2[/tex]

Write as a quadratic expression

[tex]H^2 + 4H - 252 = 0[/tex]

Expand

[tex]H^2 + 18H - 14H - 252 = 0[/tex]

Factorize:

[tex]H(H + 18) - 14(H + 18) = 0[/tex]

Factor out H + 18

[tex](H - 14)(H + 18) = 0[/tex]

[tex]H -14 = 0[/tex] or [tex]H + 18 = 0[/tex]

[tex]H = 14[/tex] or [tex]H = -18[/tex]

But Height can not be negative. So:

[tex]H = 14[/tex]

Recall that:

[tex]W = 4 + H[/tex]

[tex]W = 4 + 14[/tex]

[tex]W = 18[/tex]

Answer:

[tex]a= 2[/tex]

[tex]b = 3[/tex]

Step-by-step explanation:

Given

[tex]p(x,y) = (6,0)[/tex]

[tex]q(x,y) = (3,2)[/tex]

[tex]ax + by = 12[/tex]

Required

Find a and b

In [tex]p(x,y) = (6,0)[/tex], [tex]x = 6[/tex] and [tex]y = 0.[/tex]

This gives:

[tex]a*6 + b*0 = 12[/tex]

[tex]6a = 12[/tex]

Divide by 6

[tex]a= 2[/tex]

In [tex]q(x,y) = (3,2)[/tex]. [tex]x = 3[/tex] and [tex]y = 2.[/tex]

This gives:

[tex]a*3 + b*2 = 12[/tex]

[tex]3a + 2b = 12[/tex]

Substitute 2 for a

[tex]3*2 + 2b = 12[/tex]

[tex]6 + 2b = 12[/tex]

Collect Like Terms

[tex]2b = 12 - 6[/tex]

[tex]2b = 6[/tex]

Divide by 2

[tex]b = 3[/tex]

Answer:

so to factor out you find the greatest common factor of 14 and 7

if you have 2x-2 then you can factor out the 2 and get 2(x-1)

7=7*1

14=2*7

the greatest common factor is 7

14x-7=7(2x-1)

Answer:

4/5

Step-by-step explanation:

3/4=0.75

5/6=0.83

4/5=0.8

Answer:

Step-by-step explanation:

There actually is an infinite number of fractions between 3/4 and 5/6. But to find a simple ones make the denominators the same.

(3/4)(6/6) and (5/6)(4/4)

18/24 and 20/24 so 19/24 is halfway between them.

Answer:

C. 1324.7 cm³

Step-by-step explanation:

Volume of cylinder = πr²h

π = 3.14

radius (r) = ½ of 15 = 7.5 cm

Height (h) = 7.5 cm

Plug in the values

Volume = 3.14*7.5²*7.5 = 1324.7 cm³

========================================================

Explanation:

The ultimate goal is to find the value for lowercase c, or find the length of side c. So we'll use the portion sin(C)/c as part of the law of sines.

We don't know the value of lowercase 'a', so we'll ignore the sin(A)/a portion.

This leaves sin(B)/b

We see that one side is 2 cm long, so this means b = 2. The angle opposite this is 105 degrees, so B = 105.

The angle opposite side c is 15 degrees, so C = 15.

The lowercase letters represent side lengths, while the uppercase letters are angles.

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

We have enough to apply the law of sines to solve for side c.

sin(B)/b = sin(C)/c

sin(105)/2 = sin(15)/c

c*sin(105) = 2*sin(15) ............. cross multiply

c = 2*sin(15)/sin(105) .............. dividing both sides by sin(105)

c = 0.53589838486224

c = 0.5

Side c is roughly 0.5 cm long.

Make sure your calculator is in degree mode.

Answer:

  0.5 cm

Step-by-step explanation:

The Law of Sines tells you ...

  c/sin(C) = b/sin(B)

  c = b·sin(C)/sin(B)

  c = (2 cm)sin(15°)/sin(105°) ≈ (2 cm)(0.2588/0.9659) ≈ 0.5359 cm

  c ≈ 0.5 cm . . . . rounded to tenths

Answer:

  40 ft by 85 ft

Step-by-step explanation:

The total length of the three "vertical" partitions is ...

  3x = vertical partitions

The total length of the horizontal sides is ...

  2(x +(x +5)) = 4x +10

Then the perimeter is ...

  P = vertical partitions + horizontal sides

  290 = 3x +4x +10

  280 = 7x

  x = 40

  2x+5 = 85

The overall dimensions are 40 ft by 85 ft.

Answer:

15/8 minutes

Step-by-step explanation:

The inverse relationship implies the following equation.

[tex]t=\frac{k}{T}[/tex]

where k is a constant.

You are given a t and T that go together, so

[tex]2=\frac{k}{75}[/tex]

This implies that k=150.  Now you know that the relationship is

[tex]t=\frac{150}{T}[/tex]

Now substitute 80 for T to get the answer.

[tex]t=\frac{150}{80}=\frac{15}{8}[/tex][tex]t=\frac{150}{80}=\frac{15}{8}[/tex]
