Please help! How much is 840 miles in 3 &amp; 1/2 hours?
Ilia_Sergeevich [38]

I'm assuming your teacher wants you to calculate the speed

1/2 = 0.5

3 & 1/2 = 3 + 1/2 = 3 + 0.5 = 3.5

If a plane flies 840 miles in 3.5 hours, then,

speed = distance/time

speed = (840 mi)/(3.5 hr)

speed = (840/3.5) mph

speed = 240 mph

<h3>Answer: 240 mph</h3>

Genna threw 45 grams of sugar into 55 grams of water. She made ___ grams of ___% sugar syrup.
OlgaM077 [116]

Answer:

She made She made 100 grams of 45% sugar syrup.

Step-by-step explanation:

Genna added 45 grams of sugar into 55 grams of water.

Total amount she mixes = 45 + 55 = 100 grams.

Percentage of sugar in total mixture (sugar syrup) = 45 grams sugar in 55 grams syrup.

\text{\% by mass}=\dfrac{\text{mass of solute}}{\text{(mass of solute + mass of solvent)}} \times 100

Here, Solute is sugar  and Solvent is water.

mass of solute = 45

mass of solute + mass of solvent = 100

Putting values, we get,

\text{\% by mass}=\dfrac{45}{100} \times 100

\text{\% by mass}=45\%

Thus, She made She made 100 grams of 45% sugar syrup.
