A. If you're adding numbers with exponents with the same base, keep the same base and add the values of the exponents together.
3^2 * 3^4 = 3^(2+4) = 3^6
Answer:
Explanation:
<u>1) Calculate the volume of the water in the tank.</u>
- Area of the base of the tank: B = 7 ft × 4 ft = 28 ft²
- Height of the tank: H = 9 in = 9 in × 1 ft / 12 in = 0.75 ft
- Volume of the tank: V = area of the base × height = B × H = 28 ft² × 0.75 ft = 21 ft³.
<u>2) Calculate the weight of 21 ft³ of water.</u>
Since this is not a chemistry question but a math question, I will not use the fomula of density but set a proportion with one unknown:
- 62.4 lb / 1 ft³ = x / 21 ft³
Solve for x:
- x = 21 ft³ × 64 lb / ft³ = 1,310.4 lb.
So, rounding to the next integer, the water in the tank weighs 1,310 pounds, when it is full.

Im really sprry i do not know tgis but good luck!!
Answer:
y ≥ 2
Step-by-step explanation:
Range is the y-axis, so we have to look at the graph to find what numbers the line hits.
The line starts at y = 2 and goes up forever (the arrow indicates this), so that means that this line hits all y-values above 2.
Therefore the range is any y-value 2 or higher, so the answer is y ≥ 2.
