MrRa [10]3 years ago

Answer:

4 Blue chips

6 Yellow chips

10 Red chips

Imagine 20% as 2 of 10. We have 20 chips, and that's double of that. So if we have 2/10... we will have 4/20

Same with the yellow chips. Imagine 30% as 3 of 10, again double that... 6/20.

It doesn't directly say the percent of design a computer representation but we can infer that if we have 20% and 30%... that makes 50%, there is only 100 in a percent, so that means there is 50% left! We repeat the process where we envision 50% as 5 of 10, double that. Now we have 10 of 20, 50%!

If a snowball melts so that its surface area decreases at a rate of 7 cm2/min, find the rate at which the diameter decreases whe
vivado [14]
Surface area: S
radius: r
diameter: e
time: t

[dS/dt] = [dS/de]*[de/dt] => de/dt = [dS/dt] / [dS/de]

S = 4pi*r^2 = 4p*i(e/2)^2 = pi*e^2 => dS/de =2pi*e

dS/dt = 7cm^2 / min

de / dt = [2pi*e] / [7cm^2/min] =[7cm^2/min] /  [2pi*10cm]  = 0.11 cm/min

Factor (8xy)(3x-7y) on standard form
photoshop1234 [79]

Answer:

Step-by-sThe standard form is Ax + By = C

with A being both positive and non-fraction

so we are given 3x - 9 = 7y

we add the 9 to both sides

3x = 7y + 9  

and subtract the 7y from both sides

3x - 7y = 9
