all quadrilaterals are rectangles. False. A quadrilateral has four straight sides which don't have to be parallel to each other unlike a rectangle which has four straight sides with all four sides being parallel to one other side.

All chocolates like students? False? Not sure if I'm writing the converse correctly for this one but if I am this isn't true because chocolate doesn't have feelings...

All triangles with two or more congruent angles are a right triangle. False. This is only true when those two congruent angles add up to 90 which is when they're both 45. But they could also both be 30, 29, 28, etc... which won't result in a right triangle.

A tortoise is walking in the desert. It walks at a speed of 5 meters per minute for 62.5 meters. For how many minutes does it wa

Sergio [31]

The question is asking for how many minutes it walks. Since it walks 5 meter per minute and walks 62.5 meters, you have to divide 62.5 by 5 to get how many minutes the tortoise walks. 62.5 divide by 5 is 12.5. in minutes, 0.5 is 30 seconds, therefore the tortoise walked for 12 minutes and 30 seconds or 12 1/2 minutes.

Step-by-step explanation:

$\sf{50 \: \% \: of \: 80}$

To convert the percent into a fraction , divide it by 190 and remove the % symbol. Then , Simplify the fraction to its lowest term.

⇒ $\sf{ \frac{50}{100} \times 80}$

⇒ $\sf{ \frac{1}{2} \times 80}$

Divide 80 by 2

⇒ $\sf{40}$

Tammy bought a nightstand that was marked down 60% from an original price of $50. If she paid 10% sales tax, what was the total

AURORKA [14]

Answer: the total cost of the nightstand is $22

Step-by-step explanation:

The original price of the night stand is $50. If the original price of the night stand was marked down by 60%, it means that the amount of money by which it was reduced would be

60/100 × 50 = 0.6 × 50 = 30

The new selling price would be

50 - 30 = $20

If she paid 10% sales tax,the amount of tax paid would be

10/100 × 20 = 0.1 × 20 = 2

Therefore, the total cost of the nightstand would be

20 + 2 = $22
