A rectangle has an area of 150 square units. The width of the rectangle is 10 units and its
length is x units longer than its width.
Solve the equation 150 = 10(x + 10) to find the value of x.

Answers

150 = 10(x+10)
150 = (10x+100)
150 = 10x+100
move 100 to the other side, becomes negative
-100+150 =10x
50=10x

i need help to find m<k​

Answers

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

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.

What is a circle?

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

Given :-

In this triangle,

Base ( B ) = 15

Hypothenuse ( H ) = 39

Perpendicular ( P ) = 36

Find :-

sin x = ?

cos x = ?

tan x = ?

Solution :-

sin x = Perpendicular / Hypothenuse

= 36 / 39 = 12 /13

cos x = Base / Hypothenuse

= 15 / 39 = 5/13

tan x = Perpendicular / Base

= 36 /15 = 12 / 5

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]

The length of a rectangle is 7 centimeters greater than the width.
The perimeter is 54 centimeters. Find the length and width.

Answers

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

how many years to double investment if interest rate is .10%

Answers

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

Answers

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

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)

Jerry wants to buy 4 Michelin tires. Each tire costs $213.99. Calculate his total price if the tax rate is 7.25%.

Answers

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

Circle geometry

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:

x^2 = 289 - 225
