Solve the following:<br> a) 4x-1 / 2= x+7<br> b)<br> 3x + 2 = 2x + 13 /3

11Alexandr11 [23.1K]

Answer:

a) 2.5

b)2.33

Step-by-step explanation:

a)

$4x-\frac{1}{2}= x+7$

Bring the numerals to the right hand side and the x terms to the left hand side

$4x-x=7+\frac{1}{2}$

Simplify

$3x=\frac{15}{2}$

Divide 3 on both sides, to get x

$x=\frac{5}{2} =2.5$

b)

$3x+2=2x+\frac{13}{3}$

Bring the numerals to the right hand side and the x terms to the left hand side

$3x-2x=\frac{13}{3}-2$

Simplify

$x=\frac{7}{3} =2.33$

A cone and a cylinder have equal radius, r, and equal altitudes, h. If the slant height of the cone is l, then the ratio of the

77julia77 [94]

Given:

radius of cone = r

height of cone = h

radius of cylinder = r

height of cylinder = h

slant height of cone = l

Solution

The lateral area (A) of a cone can be found using the formula:

$A\text{ = }\pi rl$

where r is the radius and l is the slant height

The lateral area (A) of a cylinder can be found using the formula:

$A\text{ = 2}\pi rh$

The ratio of the lateral area of the cone to the lateral area of the cylinder is:

$\pi rl\text{ : 2}\pi rh$

Canceling out, we have:

$\begin{gathered} =\frac{\pi rl}{2\pi rh} \\ =\text{ }\frac{l}{2h}\text{ or l:2h} \end{gathered}$

Hence the Answer is option B
