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

The answer would be the letter c

Answer:

-32 = 3x - 4y

Step-by-step explanation:

Let's first eliminate the fraactional coefficient by multiplying both sides by 4:

4y - 8 = 3x + 24

Next, combine the constants:  4y = 3x + 32

Finally, write this result in the form Ax + By = C:

-32 = 3x - 4y

Answer:

How the Rule of 72 Works. For example, the Rule of 72 states that $1 invested at an annual fixed interest rate of 10% would take 7.2 years ((72/10) = 7.2) to grow to $2. In reality, a 10% investment will take 7.3 years to double ((1.107.3 = 2). The Rule of 72 is reasonably accurate for low rates of return.

Step-by-step explanation:

For example, if you invest $10,000 at 10 percent compound interest, then the “Rule of 72” states that in 7.2 years you will have $20,000. You divide 72 by 10 percent to get the time it takes for your money to double. The “Rule of 72” is a rule of thumb that gives approximate results

Answer:

Step-by-step explanation:

recall law of Sines :  Sin(A) / a = Sin(B) / b

where F can be A, in above equation,  and then a = 30

we want to find E so that can be B, and b = 18

Sin(78) / 30 = Sin(B) / 18

solve the parts you can

0.03260 = Sin(B) / 18

18 * 0.03260 = Sin(B)

0.5868885 = Sin(B)

use  arcSin() to find angle of B

arcSin(0.586885)  = arcSin( Sin(B))  [ b/c arcSin is the inverse of Sin those go away, they cancel each other out ]

35.9365 = B

36° = B  ( and B = E in the given triangle )

∠E = 36°

The answer is 72. 3•4•6=72 That is the volume of the figure.

Answer:

length = 17cm, width = 10cm

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

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

Answer:

The area of the triangle is six square metres.

Step-by-step explanation:

The area of the triangle is half the area of the rectangle that it fits in.  This one is particularly simple, as it's a right triangle and we're given its width and height, so it's area is:

w × h ÷ 2

= 3 × 4 ÷ 2

= 3 × 2

= 6

Step-by-step explanation:

True for the last two on the right and false for the first one

The measure of the angle ∠JKL is 230°, the area of the shaded and unshaded region is (230/18) × 5π and (325/9) × π. Then statements 1 and 3 are true and statement 2 is false.

It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

The figure is given.

Radius (r) = 10 units

Then the sum of the angle should be 360 degrees for a circle. Then

130° + ∠JKL = 360°

          ∠JKL = 230°

The area of the shaded region will be

[tex]\rm Shaded \ area = \dfrac{230}{360}\times \pi 10^2\\\\Shaded \ area = \dfrac{230}{360}\times \pi 100\\\\Shaded \ area = \dfrac{230}{18}\times 5\pi \\[/tex]

Then the area of the unshaded region will be

[tex]\rm Unshaded \ area = \dfrac{130}{360}\times \pi 10^2\\\\Unshaded \ area = \dfrac{130}{360}\times \pi 100\\\\Unshaded \ area = \dfrac{325}{9}\times \pi \\[/tex]

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
