Answer:
the number of lemons required is 6
Step-by-step explanation:
The computation of the number of lemons she required to make the 4 times the receipe is shown below;
Given that
She used three fourth of lemons for make one half liters of lemonade
Now for four times she required the lemons
= (3 ÷ 4) × 2 × 4
= 6
Hence, the number of lemons required is 6
Answer:
1/5
Step-by-step explanation:
The slope of a line at any given point is Rise/run
If I start at Point (0,2) and go to point (5,3)
I have to Rise 1 point up.
I go across, or run, 5.
1/5
It would take about 57 hours for the number of spores to be less than 500 spores.

Exponential Function</h3>
An exponential function is in the form:
y = abˣ
Where y,x are variables, a is the initial value of y and b is the multiplication factor.
Let y is the number of pores after x hours.
a = 6200, b = 100% - 20% = 0.8, hence to be less than 500 spores:

(x/5) * ln(0.8) < ln(0.08)
x > 56.4 hours
It would take about 57 hours for the number of spores to be less than 500 spores.

This solution only needs proper understanding of the word problem and identification of variables.
Let x = number of hours rental of the canoe
It costs $5 per hour for a canoe. However, for every rental of one canoe, there is a deposit of $15 regardless.
The expression is then 5x + 15.
This expression will solve how much it costs in total to rent one canoe for x hours.
To find the answer, you have to set each one equal to each other.
(160 + 40x = 55x)
Now, you just solve for X.
55x - 40x = 15x
160 / 15 = 15 / 15x
This means 160/15 = x, or is equal to
