The answers are: 4.5 g and 56.25 g respectively.
Since the first type of measurement in this question is weight or mass, I'll suppose that the percentage concentration is % mass/mass. For that type of concentration measurement, just multiply the percentage by the total mass to get the mass of the wanted material.
So 150 g * 3% = 150 g * 0.03 = 4.5g
For the 8% solution with the same amount of dry substance, use the ratio of percentages, multiplied by the mass of the first solution to get the wanted amount of new solution:
3/8 * 150 g = 56.35 g
Answer:
fourth option
Step-by-step explanation:
Using the Law of Cosines in Δ STU to find s
s² = t² + u² - 2us cosS
where t = 9, u = 10 and S = 100° , thus
s² = 9² + 10² - 2(9)(10)cos100°

Step-by-step explanation:
<u>Step 1: Define</u>
15 - (3 + 4) + 7 × 2 - 32
<u>Step 2: Evaluate</u>
- (Parenthesis) Add: 15 - 7 + 7 × 2 - 32
- Multiply: 15 - 7 + 14 - 32
- Subtract: 8 + 14 - 32
- Add: 22 - 32
- Subtract: -10
So you have those 2 rectangular prisms and the measurements are already given
Length x width x height = volume of a rectangular prism
11x10x22 = 2,420 cubic feet (the larger object)
7x4x10 = 280 cubic feet (the smaller object)
Add the 2 numbers together to get the volume of the whole figure which would be
2,700 cubic feet
Answer:
198
Step-by-step explanation:
If you take any 3-digit number and change the numbers around and subtract them you will always get 198.
