Engineering notation of the number (8.2 × 103) × (5.0 × 104) is
4.39192 × 10⁵
OR
4.4 ₓ 10⁵.
<h3>What is engineering notation ?</h3>
Engineering notation is same as scientific notation.
According to the given question
Converting (8.2 × 103) × (5.0 × 104) to engineering notation can be done using a base and raising it to the power of 10.
Base can be greater than or equal to 1 and less than 10.
Suppose base is a
∴ 1≤a<10 and the number in engineering notation will be of the form a×10ⁿ
Given (8.2 × 103) × (5.0 × 104) which is
= 844.6 × 520
= 439192
=4.39192 × 10⁵
= 4.4 ₓ 10⁵.

Answer:
The net cash provided by investing activities is $90,000
Step-by-step explanation:
In this question, we are asked to calculate the net cash that is provided by investing activities.
To calculate the net cash provided by investing activities, we simply subtract the cash used to purchase equipment from cash from sale of land.
Mathematically, net cash provided by investing activities = cash from sale of land - cash used to purchase equipment.
From the question, we can identify that cash from sale of land is $150,000 while cash used to purchase equipment is $90,000
We substitute these and get; $150,000 -$60,000 = $90,000
Answer:
Cara multiplied only 4 and 7 together and did not multiply 4 and 13.
Step-by-step explanation:
Let us evaluate the given expression step by step,
We can evaluate this expression in two ways; either by subtracting -13 from 7 and then multiply by 4 or by multiplying 4 to 7 and -13.
Now let us see where Cara made an error. We can see Cara just multiplied only 4 and 7 together and did not multiply 4 to 13.
Therefore, Cara made error in her first step.
The best estimate for 1,374 is 1,400 and the best estimate for 6 is 10. This is because anything that is 5 and above you change it. Example: 16 the best estimate for 16 is 20 because 6 is above 5. And when a number is 4 and below you change the number below. Example: 12 the best estimate for 12 is 10 because 2 is below 4. And when the number is perfect like 10, you can keep the number the same. Example:10,20,30,40,50,60etc.
Hope this Helped! :)
