On the way home from her friend's house Sandy skateboards 30% of the way, walks 1/2 of the way, and then skips the rest of the w

netineya [11]

Answer:

0.2

Step-by-step explanation:

Convert the walking to percent

$\frac{1}{2} \times 100 = 50$

Add both skateboarding and walking

$30\% + 50\%\\\\= 30 + 50\\\\= 80$

Now, subtract that from a whole percent

$100 - 80 = 20\\\\20\%$

Convert it to a decimal

$20\% = \frac{20}{100} \\\\=20 \div 100\\\\= 0.2$

Therefore, in decimal, 0.2 is the number that shows the portion of the distance Sandy skips.

What could be the base shape of a cylinder?

Len [333]

Answer:

Circle

Step-by-step explanation:

I believe the correct answer is the base shape of a cylinder would be circle. a cylinder is a closed solid that has two parallel (usually circular) bases connected by a curved surface.This is the most common kind, and if someone just says 'cylinder' this is usually what they mean. The bases can however be almost any curved shape, but the most common alternative to a circle is an ellipse. The shape would then be called an 'elliptical cylinder'. The vertical cross-section of a cylinder is a rectangle, and the horizontal cross-section is a circle.

Hope that was helpful.Thank you!!!

Emily thinks that -11/6 - (-2/3) is -5/2. Identify the error ghat emily made. Then correct Emily’s error and find the correct va

$\bf \stackrel{\textit{she subtracted }\frac{2}{3}\textit{ instead of adding it}}{-\cfrac{11}{6}-\left(\cfrac{2}{3} \right)\impliedby \stackrel{LCD}{6}\implies \cfrac{-(1)11~~-~~(2)2}{6}}\implies \cfrac{-11~~-~~4}{6}
\\\\\\
\cfrac{-15}{6}\implies \stackrel{simplified}{-\cfrac{5}{2}}\impliedby \textit{that's correct, assuming is }\frac{2}{3}~~but~is~~-\frac{2}{3}\\\\
-------------------------------$

$\bf \stackrel{\textit{recall that minus times minus is plus}}{-\cfrac{11}{6}-\left(-\cfrac{2}{3} \right)\implies -\cfrac{11}{6}+\cfrac{2}{3}}\implies \cfrac{-(1)11+(2)2}{6}

\cfrac{-11+4}{6}\implies -\cfrac{7}{6}\quad \checkmark$
