Answer:
Volume = 52.5
Step-by-step explanation:
volume of a rectangular 3d shape can be calculated by length*width*height. In this case:
7*10*0.75 = 52.5
Answer:
29.4 °F
Step-by-step explanation:
There are ten thousands in 10,000. (Amazing, eh?) So, the temperature will drop by 10 × 1.9 °F = 19 °F.
A drop of 19 °F from 48.4 °F is ...
48.4 -19 = 29.4
The temperature at 10,000 ft will be 29.4 °F.
The two solutions to the given quadratic equation are 2i/3, -2i/3 and they are both complex solutions.
Hence, option C is the correct answer.
<h3>What are the solutions to the quadratic equation?</h3>
Given the equation; 9x² + 4 = 0
First, we subtract 4 from both sides.
9x² + 4 = 0
9x² = -4
x² = -4/9
Take the square roots of both sides
x = ±√(-4/9)
Rewrite -4/9 as (2i/3)²
x = ±√(2i/3)²
x = ±(2i/3)
Hence,
x = 2i/3, -2i/3
Therefore the two solutions to the given quadratic equation are 2i/3, -2i/3 and they are both complex solutions.
Hence, option C is the correct answer.

To solve this problem, we can set up an equation, letting the unknown value of last month's supply sales be represented by the variable x.
First, we must convert 78% to its decimal equivalent, by dividing 78/100. This is because percentages are parts of a whole 100 percent.
78/100 = 0.78
Now, we are ready to set up our equation, using our knowledge that the word "of" refers to multiplication in mathematics.
3,285 = 0.78x
To solve our equation, we must divide both sides of the equation by 0.78 to get the variable x alone on the right side of the equation.
x = 4211.53846154
This means that last month's supply sales were about $4,211.54 (we round the last digit up because 8 is greater than 5).
Hope this helps!
