For lines to be parallel they must have the same slope. If:

y=mx+b

For any line to be parallel to the above it must also have the same value for m in that line.

Without calculating, would 0.4+(2+0.6) be less than , greater than, or equal to 3? Explain.

It would be greater than three because it is addition and when you add it is to increase not decrease. good luck!

You and your friend play a game. You answer 80% of the questions correctly and your friend answers 0.60 of the questions correct

bezimeni [28]

Answer:

Step-by-step explanation:

Assuming both players can answer the same question, the minimum number of questions is the smallest number that when multiplied by either 0.60 or 0.80 yields a whole number.

Let x be the number of questions, solving by trial and error:

$if\ x=2\\x*0.8=1.6\\x*0.6=1.2\\\\if\ x=3\\x*0.8=2.4\\x*0.6=1.8\\\\if\ x=4\\x*0.8=3.2\\x*0.6=2.4\\\\if\ x=5\\x*0.8=4\\x*0.6=3\\\\$

Therefore, the minimum number of questions in the game is 5.

Answer:

$100.4

Step-by-step explanation:

Compound Interest Formula:

A = P $($ 1 + $\frac{r}{100}$ $)^{t}$

=> A = 100 x ( 1 + $\frac{0.4}{100}$ )^1 = 100.4 (If they asked ... interest rate ... per year, if not then depends - most likely to be days and therefore you will need to change 1 year = 365 days and you will also need to change 1 in the formula above to 365, then you will get the right ans)
