Which is equivalent to h⋅h⋅h⋅j⋅j⋅h⋅j?
h4⋅j3, 4h⋅3j, 7(h⋅j), or (h⋅j)7?
Answers
Answer: h^4*j^3
Step-by-step explanation:
h*h*h*h = h^4
j*j*j = j^3
thus answer is h^4 * j^3
Explanation:
There are 4 H’s being multiplied by themselves meaning it’s H to the 4th power then it’s the same process with J; J to the 3rd power. Finally you’d multiply H to the 4th and J to the 3rd. I hope this helps :)
There are currently 6,210 fish in a lake. If the number of fish in the lake increased by 15 percent during the last year and 20 percent during the year before that, how many more fish are in the lake currently than in the last two years ago?
Answers
I’m pretty sure the answer should be 1,710 if not i’m sorry
Answer:
1710 fish
Step-by-step explanation:
Let the number of fish in the lake last year be 'x'
The equation becomes-
x + 15x/100=6210 (This is because 15% of x is added in x to become
6210... hope you understand)
x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400
Therefore- The number of fish last year = 5400
Now, let the number of fish in the lake 2 years ago be 'y'
The equation becomes-
y + 20y/100 = 5400 (Same logic as last time)
y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500
Therefore- Fish in the lake two years ago = 4500 fish
Difference between current and two years ago = 6210-4500
= 1710 fish
Hope you understood the answer and I hope it helps you :)

Answers
Answer: Let x be the cost of one notebook and y be the cost of one pen. Then we can write the following system of equations to represent the situation:
5x + 2y = 9
3x + 2y = 6
This system represents the fact that Samantha paid $9 for 5 notebooks and 2 pens, and Jeffrey paid $6 for 3 notebooks and 2 pens.
Step-by-step explanation:
Answer: hope this helps ♡
5x + 2x = 9
3x + 2x = 6
Step-by-step explanation:
x = cost of 1 item
Samantha → 5x + 2x = $9
Jeffrey → 3x + 2x = $6
5x + 2x = 9
3x + 2x = 6

You are looking for the price of 4 pairs of shoes after 20 days of being on sale. You have $100 and you have to find out whether you can buy these shoes.
How to solve:
After 20 days 1 pair of shoes will cost:
$40/1 x 2/5 = 16$
40-16 = 24
So 1 pair of shoes will cost $24 after 20 days.
24x4 = $96
4 pairs of shoes after 20 days cost $96. We have 100$, So we will be able to purchase it.

Answer: Company B charges $0.08x + $30.00 more than Company A for x miles.
Step-by-step explanation:
The total cost for Company A for x miles is 0.09x + 30.50, and the total cost for Company B is 0.17x + 60.50. To find how much more Company B charges than Company A for x miles, we can subtract the cost of Company A from the cost of Company B:
(0.17x + 60.50) - (0.09x + 30.50)
Simplifying the expression, we get:
0.08x + 30.00
Therefore, Company B charges $0.08x + $30.00 more than Company A for x miles.

A stunt person opens his parachute at a height of 505 feet above the ground. He then descends at a constant rate.
Let y represent his height above the ground in feet. Let x represent the time, in seconds, he spent descending with his parachute open. Which equation is represented by the graph?
Question 2 options:
y = 505x + 17
y = 17x + 505
y = –17x + 505
y = 17x – 505
Answers
Answer:
It's -17x + 505
Step-by-step explanation:
The linear equation is like y=mx+b
Solve it by using linear equation knowledge: because the graph is going down, or the height is descending, so the the slope must be negative.
And the choise of slope is 505, 17, -17, 17, so the one with negative: -17 slope is correct.
Answer:
17x + 505
y=MX+b
Solve it by using a linear equation, the graph is going down the slope must be negative
