Answer:
(–19, 55)
Step-by-step explanation:
y = –3x – 2 equation 1
5x + 2y = 15 equation 2
using equation 1 in equation 2 we have:
5x + 2(–3x – 2) = 15
5x –6x – 4 = 15
-x = 15+4
x=-19
using equation 1:
y = -3(-19)- 2
y= 57-2
y= 55
Answer:
See example below.
Step-by-step explanation:
To scale down by a factor of 1/10, multiply the side length or distance by 1/10.
Example:
If the distance was 5 then 5*1/10 = 5/10 = 1/2 is the scaled down version.
Answer:
291.05ft²
Step-by-step explanation:
Volume of the aquarium = L³
L is the length of one side of the aquarium
444 = L³
L = cuberoot[444]
L= 7.63ft
Since the glass aquarium is opened at the top
Total surface Area = 5L²
Total surface Area = 5(7.63)²
Total surface Area = 291.05ft²
Hence the minimum exterior surface area of the aquarium is 291.05ft²
