Answer:
Whether her conversion is correct or not, you can just base it on the true answer. For this problem, we apply the technique of dimensional analysis. You can like units if they both appear on the numerator and the denominator side. The solution is as follows:
Mass in ounces = 3 kg * (1,000 g/ 1 kg) * (1 ounce/28.35 g) = 105.82 ounces
Step-by-step explanation:
part A
20% of 160
0.2×160=32
the hiker can still add = 32-15=17pounds
(X)
part B
10% of 180
0.1×180=18
the hiker can still add =18-7.5=10.5pounds
(X)
For presenting home library statistical data you could use a pie chart. The parts can be things like various genres, or based on writers, or anything similar. You could make a lot of different ones about various statistical data about books and it would still be the best choice.
Answer:
Hi! The correct answer is y= -1/2
Step-by-step explanation:
<em><u>~Solve for y by simplifying both sides of the equation, then isolating the variable~</u></em>
1. 50%
2. 25%
3. 60%
Example: What is 10% of 150?
Convert the problem to an equation using the percentage formula: P% * X = Y
P is 10%, X is 150, so the equation is 10% * 150 = Y
Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10
Substitute 0.10 for 10% in the equation: 10% * 150 = Y becomes 0.10 * 150 = Y
Do the math: 0.10 * 150 = 15
Y = 15
So 10% of 150 is 15
Double check your answer with the original question: What is 10% of 150? Multiply 0.10 * 150 = 15
