i need help on number 31...

Answer:

224 lbs

Step-by-step explanation:

V = xyz = 10(14)(2) = 280 ft³

280(0.8) = 224

Answer:

angle k = 72

Step-by-step explanation:

Hey There!

When triangles are similar all of the angles that correspond with each other are congruent ( have the same value)

ex. angle g and angle m are corresponding so they both equal 70

So to find angle K we have to find the value of angle F (because they are corresponding)

So we are given two angles

remember that all angles in a triangle will add up to equal 180

so we subtract the given angles from 180 to find the missing angle

180-38-70=72

so angle F = 72

like stated earlier angle F and angle K are corresponding so if angle F equals 72 then Angle K = 72

Answer:

$918.02

Step-by-step explanation:

As each tire costs $213.99, you will be multiplying that by 4:

$213.99*4 = $855.96

Now you will have to add the tax to the price. You will do the following:

$855.96*.0725 = 62.0571

You will round that to $62.06

$855.96+$62.06

The total would be $918.02

The value of x assuming e that segments that appear to be tangent are tangent is 8

The triangle inside the circle is right angles since the side length "x" is tangential to the circle.

To determine the value of "x", we will use the Pythagorean theorem as shown:

17^2 = x^2 + 15^2

289 = x^2 - 225
x^2 = 289 - 225
x^2 = 64

x = 8

Hence the value of x assuming e that segments that appear to be tangent are tangent is 8

Answer:

(6y+0.4x)^2

Step-by-step explanation:

i just did my rsm hw so if ur here from that it's the right answer :)

(6y+0.4x)^2 Is the answer

Mouse mouse mouse

3x + y = 5

y = -3x + 5 --- (y = mx + c)

m = -3 (slope)

so, perpendicular slope = 1/3

Answer:

the elevation of the entrance is -21

Step-by-step explanation:

The computation of the elevation of the entrance is shown below;

-15 = -1 + 2 ÷ 3e

e = -21

Hence, the elevation of the entrance is -21

We simply applied the above equation so that we can determine the elevation of the entrance

Answer:

y = 5/3x + 20/3

Step-by-step explanation:

Points on the graph: ( -4, 0) and (1, -5)

Slope:

m=(y2-y1)/(x2-x1)

m=(-5-0)/(1-4)

m=(-5)/(-3)

m=5/3

Slope-intercept:

y - y1 = m(x - x1)

y - 0 = 5/3(x + 4)

y = 5/3x + 20/3

Answer:

[tex]\frac{\sqrt{21} }{5}[/tex]

Step-by-step explanation:

Given

cosθ = - [tex]\frac{2}{5}[/tex]

Using the identity

sin²θ + cos²θ = 1 , then

sinθ = ± [tex]\sqrt{1-cos^20}[/tex]

       = ± [tex]\sqrt{1-(-\frac{2}{5})^2 }[/tex]

      = ± [tex]\sqrt{1-\frac{4}{25} }[/tex]

      = ± [tex]\sqrt{\frac{21}{25} }[/tex]

     = ± [tex]\frac{\sqrt{21} }{5}[/tex]

Since θ is in second quadrant the sinθ > 0 , thus

sinθ = [tex]\frac{\sqrt{21} }{5}[/tex]

Slope is -2/3 :)

Answer:

In this triangle,

sin x = ?

cos x = ?

tan x = ?

sin x = Perpendicular / Hypothenuse

= 36 / 39 = 12 /13

cos x = Base / Hypothenuse

= 15 / 39 = 5/13

tan x = Perpendicular / Base

= 36 /15 = 12 / 5

Questions:

A clothing manufacturer uses the model a = √(f + 4) - √(36 - f) to estimate the amount of fabric to order from a mill. In the formula, a is the number of apparel items (in hundreds) and f is the number of units of fabric needed. If 400 apparel items will be manufactured , how many units of fabric should be ordered?

Answer:

32 units of fabrics

Step-by-step explanation:

Given

[tex]a = \sqrt{f + 4} - \sqrt{36 - f}[/tex]

Required

Find f when a  = 4

Substitute 4 for a

[tex]4 = \sqrt{f + 4} - \sqrt{36 - f}[/tex]

Rewrite as:

[tex]\sqrt{36 - f} + 4 = \sqrt{f + 4}[/tex]

Square both sides

[tex](\sqrt{36 - f} + 4)^2 = (\sqrt{f + 4})^2[/tex]

[tex](\sqrt{36 - f} + 4)^2 = f + 4[/tex]

[tex]36 - f + 8\sqrt{36 - f} + 16 = f + 4[/tex]

Collect Like Terms

[tex]8\sqrt{36 - f}= f +f+ 4 - 36 -16[/tex]

[tex]8\sqrt{36 - f}= 2f -48[/tex]

Divide through by 2

[tex]4\sqrt{36 - f}= f -24[/tex]

Square both sides

[tex]16(36-f) = (f - 24)^2[/tex]

[tex]16(36-f) = f^2 - 48f + 576[/tex]

[tex]576-16f = f^2 - 48f + 576[/tex]

[tex]-16f = f^2 - 48f[/tex]

Collect like terms

[tex]f^2 - 48f + 16f = 0[/tex]

[tex]f^2 -32f = 0[/tex]

Factorize

[tex]f(f - 32) = 0[/tex]

[tex]f = 0[/tex] or [tex]f = 32[/tex]

f can not be 0 because some units must be ordered.

So, f = 32

Answer:

Step-by-step explanation:

2L + 2w = 54

L = w + 7

Substitute:

2(w + 7) + 2w = 54

2w + 14 + 2w = 54

4w = 40

w = 10

L = 10 + 7 = 17
