Answer:

The answer to your question is below

Step-by-step explanation:

1) The triangles are similar by the AA postulate so use proportions to find x.

x/207 = 170/90

solve for x

x = 207(170/90)

x = 207(1.89)

x = 391 ft

2) These triangles are similar so use proportions to solve it

x/138 = (x + 60)/207

207x = 138(x + 60)

207x = 138x + 8280

207x - 138x = 8280

69x = 8280

x = 8280/69

x = 120

The aspect ratio (the ratio of screen width to

stira [4]

Answer:

$Width = 36in$

$Size = 42.02$

Step-by-step explanation:

Given

$x \to width$

$y \to height$

$x : y = 16 : 9$

Required

The size of $screen$ of height $20,6in$

First, we calculate the width using the following equivalent ratios

$16: 9 = x : 20.6$

Express as fraction

$\frac{16}{ 9} = \frac{x }{ 20.6}$

Solve for x

$x = 20.6 * \frac{16}{ 9}$

$x = 36.62$

Hence:

$Width = 36in$ --- approximated

So, we have:

$x = 36.62$

$y =20.6$

The size (diagonal) is then calculated using:

$Size = \sqrt{x^2 + y^2$

$Size = \sqrt{36.62^2 + 20.6^2$

$Size = \sqrt{1765.3844$

$Size = 42.02$

$Size =42in$ --- approximated

Find the exact length of the curve. x = 1 + 6t2, y = 4 + 4t3, 0 ≤ t ≤ 3

vovangra [49]

$x=1+6t^2\implies\dfrac{\mathrm dx}{\mathrm dt}=12t$

$y=4+4t^3\implies\dfrac{\mathrm dy}{\mathrm dt}=12t^2$

The length of the curve $C$ is given by

$\displaystyle\int_C\mathrm ds=\int_0^3\sqrt{\left(\frac{\mathrm dx}{\mathrm dt}\right)^2+\left(\dfrac{\mathrm dy}{\mathrm dt}\right)^2}\,\mathrm dt$

$=\displaystyle\int_0^3\sqrt{144t^2+144t^4}\,\mathrm dt$

$=\displaystyle12\int_0^3t\sqrt{1+t^2}\,\mathrm dt$

$=\displaystyle6\int_0^3 2t\sqrt{1+t^2}\,\mathrm dt$

$=\displaystyle6\int_0^3\sqrt{1+t^2}\,\mathrm d(1+t^2)$

$=6\cdot\dfrac23(1+t^2)^{3/2}\bigg|_0^3$

$=4(10^{3/2}-1)$

$=40\sqrt{10}-4$

Mrs ndlovu finds the perfect fridge online with the following dimensions: 70inches ×1.7 yards ×2.4 feet will the fridge fit ? sh

Orlov [11]

The dimensions of the fridge are the length, width and the height of the fridge

The volume of the fridge is 123379.2 cubic inches

<h3>How to determine the volume of the fridge</h3>

The dimensions are given as:

70 inches ×1.7 yards ×2.4 feet

Convert the dimensions to inches

70 inches × 61.2 inches × 28.8 inches

So, the volume is:

Volume = 123379.2 cubic inches

Hence, the volume of the fridge is 123379.2 cubic inches
