Find the smallest number such that the remainder is 3 when it is divided by 16,20 or 24.​
schepotkina [342]

Answer: 123

Step-by-step explanation:

Foe us to solve this, we have to find the lowest common multiple of 16, 20 and 24 first and then add 3 to the LCM. This goes thus:

Multiples of 16 = 16, 32, 48, 64, 80, 96, 112, 128, 144, 160

Multiples of 20 = 20, 40, 60, 80, 10, 120, 140, 160

Multiples of 24 = 24, 48, 72, 96, 120

Therefore, the Lowe's common multiple is 120.

We then add the remainder of 3 and this will give:

= 120 + 3

= 123

Line e passes through points (7, 8) and (4, 10) Line f is parallel to line e. What is the slope of line f?
Tatiana [17]
<h3>Answer:  -2/3</h3>

==================================================

Explanation:

Use the slope formula to find the slope of line E

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

m = (10-8)/(4-7)

m = 2/(-3)

m = -2/3

The slope of line E is -2/3

The slope of line F is also -2/3 since parallel lines have equal slopes but different y intercepts.

An ice cream cone is filled with a vanilla and chocolate ice cream at a ratio of 2:
nirvana33 [79]
\bf \textit{volume of a cone}\\\\&#10;V=\cfrac{\pi r^2 h}{3}\quad &#10;\begin{cases}&#10;r=radius\\&#10;h=height\\&#10;----------\\&#10;diameter=2\\&#10;r=\frac{diameter}{2}\\&#10;\quad = 1\\&#10;h=6&#10;\end{cases}\implies V=\cfrac{\pi\cdot  1^2\cdot 6}{3}&#10;\\\\\\&#10;V=2\pi \\\\&#10;-------------------------------

\bf \cfrac{\stackrel{vanilla}{volume}}{\stackrel{chocolate}{volume}}\qquad 2:1\qquad \cfrac{2}{1}\implies \cfrac{2\cdot \frac{V}{2+1}}{1\cdot \frac{V}{2+1}}\implies \cfrac{2\cdot \frac{2\pi }{2+1}}{1\cdot \frac{2\pi }{2+1}}&#10;\\\\\\&#10;\cfrac{2\cdot \frac{2\pi }{3}}{1\cdot \frac{2\pi }{3}}\implies \cfrac{\quad \frac{4\pi }{3}\quad }{\frac{2\pi }{3}}
