Answer:

80%

210%

65%

105%

Step-by-step explanation:

To solve for each of these equations, let's make them fractions first. The denominator will be 20 since that was the goal.

Elena did \frac{16}{20} pushps.

Jada did \frac{42}{20\\} pushups.

Lin did \frac{13}{20} pushups.

Andre did \frac{21}{20} pushups.

To convert this to percentages, let's multiply each by fraction by \frac{5}{5}. This will give us a denominator of 100. The denominator will represent the percentage.

Elena did \frac{16}{20} × \frac{5}{5} = \frac{80}{100} pushps. Elena did 80 percent of the pushups.

Jada did \frac{42}{20\\} × \frac{5}{5} = \frac{210}{100} pushups. Jada did 210 percent of the pushups.

Lin did \frac{13}{20} × \frac{5}{5} = \frac{65}{100} pushups. Lin did 65 percent of the pushups.

Andre did \frac{21}{20} × \frac{5}{5}  = \frac{105}{100} pushups. Andre did 105 percent of the pushups.

How many milliliters of 0.30% sugar solution must you add to 75mL of 4% sugar solution to get a 0.50% sugar solution?
hammer [34]
Based on the given data above, the equation below has been generated,
(X mL)(0.003) + 75 mL (0.04) = 0.005 (75 + X); X being the amount in mL of the sugar solution, by further simplification of the generated equation, it can be said that 1312.5 mL of 0.30% sugar solution should be added to 75 mL of 4% solution to come up with a 0.5% sugar solution.
